Had a great experience working with Daniel and his team. Great guys and hard workers. Very satisfied with their service. Highly recommend.

Had some French drains and a sump pump put in to address some water drainage issues. Thought it was going to be a headache but they made it easy. Professionals in all aspects. I even had neighbors coming over to compliment what a great job they did! Took great care of my landscaping in the proces, arrived on time and completed the job when they said they would. Were proactive about safety, Just did great work all around. Could not be happier wit's their work. read more

Bay Drainage did an outstanding job at our home. They built a deep, properly designed French drain and rock solid sump system that addressed the water issues the right way, not as a temporary patch. The crew was professional, hardworking, and clearly knew what they were doing. What impressed me most was the care they took with the property -- they were meticulous about preserving existing paths, tile, and plants, and the cleanup was excellent. The finished work looks great and feels built to last. I'm extremely satisfied and would absolutely recommend Bay Drainage to anyone who wants the job done right the first time. read more

They started on time and finished the job early. They were very quiet and respectful of my property and cleaned up the workplace every day and even hosed off the street. They finished the project ahead of schedule and did more than what they had contracted to do. I highly recommend them for their professionalism, punctualit, and getting th Job done! read more

Bay Drainage did an excellent job with installing french drains and a sump pump system at my house. They were professional, worked hard, and you'd never know they were here now. The system is working as intended and now I'm not so stressed when it rains. I would highly recommend! read more

We had a problem with proper drainage under our deck. The deck was installed next to a wall that we share with our neighbor, and when it rained, water would leak into her home through the wall. There must have been a crack along the wall below the dirt surface for water to seep across. Dave came promptly to look at it and explained it all to me. He was very courteous and even funny. He gave me a reasonable estimate and even gave me a generous discount after removing the deck boards to further assess the problem. His crew is very hard working and courteous and finished the work promptly. They ended up removing the extra dirt, installing a new drain, waterproofing the shared wall, and installing a French drain along the shared wall. After the deck boards were replaced, we water tested the area thoroughly to make sure that the leaky wall was patched and sealed. If you have a drainage problem, I highly recommend Dave and his company, Bay Drainage. Dave is an expert with drainage issues and will do his best to address your needs and problems. read more

Stay far away from this company. We hired Bay Drainage to install a french drain inside our house. This involved cutting and breaking the concrete floor in our storage room. Dave told us we could leave our belongings in the room and did not have to worry about dust as they would spend the first couple hours covering every surface with plastic wrap. This matched our expectations from past remodeling and construction jobs with other contractors. The day the work started, the concrete saw was running 30 minutes after Dave and crew arrived, and soon after two of our smoke alarms were going off due to the excessive amount of dust. The air cleaner upstairs also started running full blast, and it was getting hard to breathe anywhere in the house. We asked them to stop the work, moved some of our belongings, and left the house for the rest of the day. In retrospect, we should have just told them to stop completely. When we came back later in the day, the air cleaner was still running full blast, and we were able to see the work site for the first time. Dave's crew had done an extremely shoddy job with the insulation -- there were big gaps between the plastic wrap and the floor/ceiling, and some areas were completely uncovered. Due to this, every surface in the storage room, and all of our belongings, were covered in a thick layer of fine concrete dust, which is known to have serious health effects including silicosis and lung cancer. The dust has completely penetrated our electronics, camping gear, chair cushions, and clothes. There was even a layer of dust inside closets in the next room. It was absolutely everywhere. When I talked to Dave about this the next day, instead of taking responsibility for his crew's mistake like a professional, his initial reaction was to fold his arms like a kindergartener and say "construction is messy, what do you want me to do about it?" He incorrectly claimed the concrete dust is nothing to worry about ("dust is dust, your lungs can handle a bit of dust"), but finally admitted they did a "sh*tty job" and agreed to pay for a cleaning crew after I showed him the pictures. We've had extensive work done on this house (fully remodeled a kitchen and 2 bathrooms, and had asbestos tiles removed) and never had a single speck of dust anywhere. Our previous contractors took the time to insulate their worksites the right way, and had airtight insulation. The mess we've had to deal with after this job was beyond anything I could have imagined. I do not understand how they managed to stay in business for all these years. We hired a professional post-construction cleaning company to clear the bulk of the dust, and we spent hours every day for over a week dusting and wiping everything over and over again to get the remaining dust out of everything. We also had to throw out bags of stuff that we couldn't possibly clean. For full transparency, we did manage to negotiate a discount that doesn't even begin to make up for the pain we went through. I cannot, under any circumstances, recommend working with this company. In hindsight, another rainy winter without a french drain might have done less damage to our house and our belongings than Dave's crew has. read more

We hired Bay Drainage to install a french drain around our house. When Dave first came out to take a look at our house, we were expecting the worst. We had already had a quote from a very well reviewed company that was so high, it was astonishing. Dave came out, looked at our problems, and proposed a much simpler solution. He understood what we needed, took into account where the water was coming from, where it needed to go, and figured out a clear, concise method to divert it around our house. Dave's crew are all extremely hard workers. They are precise, efficient, and they clean-up after themselves! Dave oversaw the project and was able to make changes along the way as needed. I can't say enough kind things about Bay Drainage, Dave, and his crew. I will recommend them to anyone that I know in the future that needs help with water issues. read more

Dave and the crew at Bay Drainage are amazing. My wife and I undertook a massive back yard remodel - pool, retaining walls, pavilion etc. What started out as a simple project to put in a French drain alongside the house turned into drainage throughout the entire remodel - French drainage behind retaining walls, sump pump for pool and surface drains for landscaping. Dave bailed us out countless times when other contractors failed to show or led us down the wrong path. He basically stepped in to GC project on his own dime! Dave is super honest and a real expert in this space. He's been around! His crew is great, showed up everyday and they work hard! He's worked w a number of our neighbors on various projects since ours and I can't thank him enough. Rest assured that Dave /Bay Drainage will handle your drainage needs! We are super grateful for all of his help! read more

We had a drainage problem around our home which resulted in flooding after every major winter storm. Dave assessed the problem, gave us a clear proposal for how it was going to be fixed, and his team proceeded to install a new drainage system with precision and excellence. From start to finish, this was one of the best home improvement projects I have ever experienced. Dave and his crew were accommodating and definitely know their business. The team did a great job for a fair price. They deserve a five star rating. read more

I Hired Bay Drainage originally for a full drainage retrofit on a recommendation from a friend, adding drainage + sump to the property plus french drains all around the foundation. I was happy enough with the work and the management of the project that I had Dave (owner) come back for several other large jobs since. Regarding the drainage work, first of all the prices for the provided quality of the work were great. I have worked with a lot of contractors and in my experience the company is a great deal in terms of work completed per dollar. Technically the quality of the drainage work was above average, they use a 2-drain system, one for the downspout/surface-drain and another for the french drains, ensuring that your downspouts do not drain into your foundation. They use the appropriate fill materials around the drainage, the french drains were around 4' deep and the sump was over 12' deep. Company-wise, Dave was on the property every day the work was performed often multiple times a day. Communication-wise Dave was excellent and flexible on the small changes/additional that came up. The employees are wearing uniforms (shirts) show up on time, in company trucks, are respectful and friendly, and are well trained. About a year after the drainage work was complete, I had not cleaned out the sump and the 2022 atmospheric river hit and it was not able to keep up. I called Dave and he was there in 15 minutes on hands and knees pulling out my sump pump and cleaning off the leaves. He sent an employee the next week to vacuum up additional debris from the bottom of the sump, didn't charge me. I have had Dave back to work on a number of other jobs since over $40k worth, pavers for the driveway/patio, entire sprinkler system, landscaping, planting, turf installation, and more. Overall, highly recommend, great company, good work, at fair prices. Also, one tip, Dave is Canadian, so you can pay in Canadian dollars and he won't notice, this can save you significant amount of money (/s). read more

Dave and his crew just finished up installing a French drain system around the foundation of our whole home. The crew was extremely professional and cleaned up at the end of each day. All in all, the project took about 3 weeks and during this time Dave was extremely communicative and made sure to answer any concerns we had. The aftermath of trenching in the rain created some mud stains on our stucco which didn't come off with regular cleaning. Dave went above and beyond in re-stucco'ing half our home. Overall, we're extremely happy with the level of professionalism and workmanship of Bay Drainage. Would highly recommend to anyone. read more

It works. Dave's team did the drainage job on the hill side of my home. The crawl space used to be wet in 2017 or 2018 (don't remember which year). A friend in Pleasanton told me that's normal, but I doubted. I ask Dave twice and he mentioned it's good to install drainage on the hill side to block the underground water from coming into crawl space. 2022 winter has lots of rain, and it works. My crawl space is totally DRY, I am so surprised it could be totally dry. My expectation was no standing water, but it's DRY. Dave answer my questions before/during and after the projects. Ceaser who did the job onsite knows what he was doing and he is really experienced. read more

I had Dave do a French drain and retaining walls around 2016. Portions of the wall started to lean a year after the install, he came and fixed it. Over the past 2 years more of the wall has started to lean. I've tried reaching out to him numerous times over two-year period, but he has not responded to calls or emails. I don't like leaving bad reviews but he's leaving me no choice. During the installation, I was working from home, so I kept an eye on the workmanship. On three occasions he had to dismantle and redo the retaining wall due to poor workmanship that I pointed out. It included not securing the blocks as directed by the manufacturer, not following manufacturer specifications for the foundation layer and installing the drainage perforated pipe upside down. As for the French drain, once it's installed and buried, you have no idea if it was installed correctly. A couple of years later I had to do some additional landscape work that required me to connect to the drainage that Dave installed. I found an incorrectly installed perforated pipe (holes are facing sideways instead of down. Basically non-functional) and found a pipe joint that had come apart due to poor gluing practice probably because it was wet (which explained the excessive wetness in that area) At this point, due to Dave's lack of responsiveness, I have no choice but to have someone else fix Dave's poor installation at my expense. Dave's a nice guy, but his failure to call back and address his workmanship issues caused me to write this review. Based on my experience at my house and his lack of responsiveness, I would be very cautious doing business with him. read more

Our retaining wall project was pretty straightforward, but the town made getting permits quite difficult. Dave was persistent and persuasive in getting the necessary supporting documents and, ultimately, the permit. He and his guys did a fantastic job on the project and the communication was excellent. We are super happy with our new wall and Dave was very enjoyable to work with. read more

We called a couple of drainage places to come out and give a quote, Dave was the only one that told us to hold off on doing anything, wait for a couple of storms to happen to see if we truly have a drainage issue. While the other places quoted me $40k to install French drain immediately. There was a big storm last week, Dave came out to look at the house again and turned out we had no drainage problem! Thanks to his expertise and integrity we didn't have to dig up the entire house and install something we didn't need in the first place. Absolutely recommend! Good business practice. read more

Just updating from my earlier review that about 18 months in, everything is still just as expected. Great job to the Bay Drainage team. read more

This is an update to my original review of Bay Drainage. Since installation of a back yard sump pump in 2019, I have enjoyed a dry basement, even through last year's atmospheric river. Thank you Bay Drainage! Now a 2nd atmospheric river is upon us. My sump put acted up Friday and I called the owner - Dave Wilson. Within an hour Dave sent one of his guys out and he fixed everything. I love that this company provides such good service and takes time to answer all my questions. I also am impressed that the same employees are here after four years. Bay Drainage is doing something right. read more

Bay Drainage and Dave were wonderful to work with on our big French drain installation project! We cannot say enough good things about Dave and his team!! We just bought our home last Fall and we soon learned that we would need a serious upgrade to the existing (poor) drainage system. While our foundation was in good shape, we were advised to consider a French drain to protect it. And given how important the foundation of your home is, we knew we needed to call in the pros versus having a landscaper install one. We collected a few bids and Bay Drainage's price was competitive. We also appreciated how responsive Dave was when we had several questions about his bid. He was always quick to respond whereas it took sometimes days to hear back from his competitors. Dave and Bay Drainage also came at the recommendation of a big, local foundation company (who had also suggested we consider a French drain to protect our foundation). Once we scheduled a start date, Dave and his team showed up on time everyday. They were able to install a French drain around the perimeter of our house and also connected all of our downspouts into the drainage system. We really appreciated how much Dave cared about the quality of his work. That's a nice touch that you don't have to worry about! Also, Dave was very communicative throughout the entire project. The Bay Drainage team worked really hard, were polite and friendly, and they also cleaned up at the end of each day. The end product looks and works great! We feel very confident about how well protected our home is now. Even our neighbors are all impressed with our drainage system! We definitely recommend Bay Drainage if you are considering a French drain for your home!! We really enjoyed working with Dave and his team, and we will hopefully get another chance to work with them on a retaining wall we now want to put in our backyard! We cannot recommend Bay Drainage enough. Dave and his team are good guys that you can trust!! read more

I can't say enough about the professionalism and the over, above and beyond quality work that this company has done. I checked them out and let me tell you their work was great.

My sixty-two year old house in the East Bay Hills desperately needed French drains; the beautiful hardwood floors in the lowest level of the house were buckling. I always prefer to work from recommendations, so I started by speaking with my neighbors. Fortunately, one neighbor, whose house is a decade older than mine, had French drains installed several years before. The process he described seemed daunting: the guys have to dig to below the foundations, and they have to inspect the foundations for cracks. Be sure to confirm ahead of time that the drains will be installed below the foundations...the list went on and on, and I was overwhelmed. When I asked for the contact information of his contractor, he said the guy had retired! So, I spoke with another neighbor, whose French drains had been more recently installed. Not only did she confirm everything the first neighbor had said, but she had a recommendation, as well: Dave, the owner of Bay Drainage. She said he had a terrific crew, he was there every day supervising and directing their work, and the project was completed in a timely manner. I called Dave. The first thing he asked me when he came to my home was, "How do you know you need French drains?" I found that an odd question, but told him about the hardwood floors that were buckling. After a bit of poking around in the basement, he acknowledged that indeed, I really did need French drains! He drafted a contract, but before he sent it to me, he said, "I give a 5% discount for senior citizens, so be sure to remind me before you sign the contract." (That was an easy thing to remember!) I am so happy that I found Dave! He gave me an approximate date when my project would start, and it started within a few days of his estimate. His crew arrived every day about 8:30 A.M., and worked steadily. When an unusual amount of noisy work was expected, I was warned ahead of time. His guys were polite, professional, and wore masks. The entire project was completed in less than a month. When I asked him how long I could expect the drains to last, he said they have a lifetime guarantee. As lifetimes vary in length, I asked him whose lifetime was being used as the measurement! He said he is training his son to take over his business, so I am passing the signed contract to my adult children! If your house needs French drains, I highly recommend Dave! read more

Dave and his team did a great job replacing all the outside drains around our house. The project took a week, and when finished the yard looked just as before. There were a few call backs for broken sprinklers which were fixed quickly. I would highly recommend Bay Drainage. read more

Finding an honest, reliable, and financially reasonable drainage specialist is hard to come by, but Dave and his team delivered 100%. I moved into a new house and discovered that water was seeping into the basement. I had Dave come out and he told me I needed French drains. I decided to address our immediate needs first and do the minimal amount of drain work needed based on cost. Then it rained A LOT and water came into the basement from other areas. Dave came back and told me that I needed French drains again and walked me through the parts of the house where the water was seeping in and where the drains would fix it. I'm an academic, so by nature, I have A LOT of questions. He patiently answered all of them and walked me through each step, which I really appreciated. In the end, our French drains were complete in 2-3 weeks. We haven't had any water in the basement and I can rest assured that if any problems do arise in the future, I can always call Dave. read more

Our home was flooded with water. Dave with Bay Drainage was amazing and highly professional. This was by far the best investment we have made thus far to our home. Reliable, timely, efficient, excellent craftsmanship, they far exceeded our expectations! We would highly recommend Bay Drainage and plan to use them for a long time. Words can't express out gratitude and support for a local company. read more

Dave was responsive and efficient. He installed a new sump pump. The work was done timely and at a reasonable price. I highly recommend him.

Bay drainage is the best! Dave is really honest and reliable. We are really thankful for having him and bay drainage install our drains. They know what they're doing and don't cut corners. Now that it's storming here, we are grateful for their great service and reliability. Dave spent a lot of time with us and reviewed the project repeatedly. He was always available. Totally recommend them. read more

This review is long overdue. I cannot say enough good things about Dave and his team. Dave was the glue that held our entire project together - even the portion that was done by another vendor (foundation work) and not his responsibility to oversee. He was here every day making sure everything was completed on time and, most importantly, done correctly. He went above and beyond to put things back together that weren't his responsibility and made sure that we were never double charged if there was work that the other vendor did that was originally in his bid. Our new French drain is working great and we couldn't be happier. read more

I'm giving these guys 1 star because of their lack of response/professionalism. I called them twice, left vms each time, and got no response. I understand that we live in the bay area which is significantly overpopulated and the good contractors are overwhelmed with business. However, as a professional courtesy, it would be nice just to receive a phone call back. Frustrating when you see a company that's highly rated but not reachable. read more

Worked directly with Dave on a Commercial property, Drainage & Asphalt, three-month drainage project spanning July to October. Planned timeline to encompass multiple parties and tenants. Strategized with Civil Engineering, City of Concord. Authored owner proposal deck and secured Building & Encroachment permitting. Negotiated budget, directed contractor's in 1) drainage for floodwater mitigation, 233 linear feet of surface drainage, installation of Zoeller high flow sump pumps, gravity overflow to street, collection of rooftop downspouts 2) parking lot asphalt, designing reserved numbering parking spaces, and curb property lines. Dave was straight forward, punctually communicating timeline when requested to, thus responsive to customer personal preferences. Dave also being that he's been in business for decades, has contacts in the industry which allowed us to also design and update/upgrade our asphalt/parking lot. All together, it was a pleasure and great experience working with Dave and Bay Drainage. - Wilson of Metrotuned Real Estate Property Management. read more

Dave came out today to give us a quote for what we thought would be a lot of work to fix a mold problem. Instead, he told us that we just needed to repair some stucco issues and possible look at our roof.

Dave and his team are excellent at what they do. We bought an older home that had drainage issues and Dave promptly came over to assess what was needed. We moved forward with a French Drain solution and his crew worked efficiently over the course of 10 days to install. The crew was respectful, cleaned up at the end of each day, and worked around my work schedule for the jackhammering (I work from home). About a month after the work was done, we had a big rainstorm, and I identified an surface area that required an additional surface drain. Dave did not hesitate to come back out to install it as part of the his lifetime guarantee. Highly recommend Bay Drainage! read more

We were selling our house and needed to deal with a small amount of water under the house where we had a sump pump. I called Bay Area Drainage on a Friday and Dave came by within the hour - wow!! He gave a rough quote and then confirmed a solid quote in writing (which was at the lower end of the original quote and very reasonable). Dave fit us into the schedule for the next week and actually ended up being able to start a day early. His crew was wonderful - pleasant and hardworking and they cleaned up every day. The foundation ended up being taller than expected which meant a deeper hole and more time than he anticipated but they honored the original quote. We now have a new drain in the area and the sump pump is gone and it is dry, dry, dry! Hooray! Thank you Bay Drainage for being prompt and professional. :) read more

Dave and his very VERY hardworking crew installed a french drain, hard-pipe drain (tied into our gutter downspouts) and sump pump to move water away from our foundation. The crew was very careful with nearby trees/roots and considerate to our neighbors - so appreciated! We found Dave to be very knowledgeable and professional; his price was reasonable and we are happy with the end results. In fact, we plan to use Dave again for landscaping and hardscaping! read more

Bay Drainage came recommended to me by a foundation repair company. When I first spoke to them, they said that they don't ordinarily come down to south San Jose, but they would do so. The day before my appointment, I receive a call that the person coming down was sick so they'd get back to me. Never heard back, despite my text to follow up. It's not a big deal if they didn't want to come down to quote me in the first place. But the professional thing, instead of taking the appointment and then canceling, would've been to just say that. Then I wouldn't have blocked out my morning on my calendar for them. read more

We had a major drainage issue last year, no drains, all the rain resulted in flooding and even damage to my home. I called bay drainage, Dave, they were extremely responsive and personable. He came out to my house with in 24 hours, gave me a great quote and honest advice, not trying to upsell or oversell, just what I needed to make my home and property safe. Now let me tell you about the work, holy fast crew, these guys come to work!!!! They run with wheelbarrows full of clay soil, impressive to say the least. I had a French drain system installed around my entire home, surface drains every 8 feet, and 2 sub pumps. They had to cut my pool deck to install the French drain in that area, repoured my pool deck to completely match. Depth, like I said these guys work, the depth of the trench was deeeeep! I had two areas of concrete that need to be poured going to my front doors, both were poured and correctly sloped to drain away. I have absolutely complete piece of mind because of Dave and Bay Drainage. Super nice guy, I have had questions about the service even after the job was competed, responds to texts in minutes. Let it rain!!!!!! read more
