I was in a pinch right and needed a estimate for drainage right after a big storm. Rich was able to come out next day and make it happen despite a tsunami of other inbound requests from others in similar situations. 5 stars for professionalism, service, and willingness to go the extra mile. read more

We had a drainage issue in the backyard, so we called Drainage Pros to come take a look. Unfortunately, our house was built nearly a hundred years ago, so the whole system of non-functional sumps and discharge lines needed to be rebuilt. Drainage Pros were able to walk us through what needed to be done, lay out solid estimates, and get the job done. Everything was fixed up before the next round of rainfall, and we're looking forward to not having these issues again. Would definitely recommend. read more

Rich and the crew at Drainage Pros were awesome. Like most of our Poets Corner neighborhood, we had flooding and drainage issues during the winter of 2017. After that tough rainy season, we did our homework, received multiple estimates and went with Rich after meeting him a few times. The project started late last year. The price was fair, the work was expert and the interactions friendly and filled with recommendations. They held our hand when we needed help and listened to us when we had concerns, however small. Our fathers were both construction management engineers for decades and they were both consistently impressed with the craftsmanship and dedication from Drainage Pros to do things the right way, even when it took more work. They ran into a few problems on the property but adjusted their plan and worked with us on solutions without breaking the bank. We made it through the winter of 2018 with zero drainage issues and we're looking forward to working with this team again on our next big project. We would wholeheartedly recommend Rich and Drainage Pros to any family looking to get a fair shake from a blue-collar, hard-working local crew that does things the right way. read more

I purchased my house in Richmond 3 1/2 years ago. There had been water under the house every winter since the house was built. By installing a series of drains, rehabbing a French drain and installing a sump pump, Drainage Pros have kept my crawl space bone dry. Their yearly inspections and off cycle clearing of a bark chip out of the sump pump keep thing running in peak condition. A great company. read more

Let me start with this...You do have to pay for the quote. You do have to maybe wait a few minutes past your appointment time. You may even wait to receive your estimate. But I can say it was all worth it. The lower level (basement) of my home flooded and had seen many contractors all confused about how to resolve my drainage issue. I had a REALLY bad situation and a unique circumstance being that I purchased the home from a flipper who covered everything up (another story). I searched online and found Drainage Pros. I decided to call them since their specialty was drains. I was given an appointment and the owner, Rich, showed up to assess the issue. He was really confident that his company could fix my problem by installing drains around the entire perimeter of my home and I was provided a quote shortly thereafter. This company is not the cheapest by any means... BUT they were the most knowledgeable. My project was a large project scheduled to take about 2 weeks. Lead Foreman Berto was assigned to my job and was very professional throughout the entire process. The company's workers always showed up on schedule and made things as comfortable as possible for me. Drainage Pros cleaned up the work area and left my home looking very clean and nice. I did end up having a very minor water intrusion issue a little after the drains were installed, but Rich made sure to get his crew out here and work to resolve the issue even if it meant opening back up a piece of the concrete to see below the ground. I absolutely love Rich's integrity and his willingness to make sure that his company's work is done well and that the customer is happy. I must say that this company has shown me that they stand by their word. Fast forward to a little over 2 years and the drainage system seems to be working as it should! I have not had any water appear on the floors of my lower level and I'm not as nervous about my property when it rains. I would recommend that you use Drainage Pros if you need honest folks who know what they are doing. read more

See all

Disappointed that there is a fee of $350 for estimates. How am I to compare if fees are charged?

I spoke to Rich over the phone about a drainage project I am planning on starting soon. He was able to provide me with an written and emailed estimate on the scope of work and price range. I was pleased with the quick response in sending the quote the same day. read more

Long overdue update. Exterior french drains were installed. The crew, led by Javier, finished the job on time. The site was maintained clean and orderly throughout the project. I am very satisfied with the experience I had, and would not hesitate to recommend Drainage Pros for an exterior french drain project. read more

I have been working with Rich and the team at Drainage Pros for almost a year now. We work almost everyday together. We deliver rock all over the East Bay for a variety of uses including Drainage. I can say that Rich is one of the authoritative voices in this industry. He knows drainage like the back of his hand. I've delivered rock to big site and small sites and he has the team that can handle any work. Every time I talk with him he speaks well about his customers and shows true respect. He just gets the job done and done well. Fully recommended! read more

I also want to add on that Rich and his crew came out to my house following their amazing job to address issues unaffiliated with the initial project. I had broken pipes that weren't their fault, but because rich and his team care about the environment and didn't want water wasted, helped me alleviate that problem. I would highly recommend them to anyone who is having drainage problems. Honest, attentive and thorough. I wish more companies acted this way. read more

Update: Rich promptly called back after this post, and I now have his direct line. We've got a plan and I'm feeling good about it. He's working through an employee training issue, but we should be good moving forward. Thanks Rich! ------------------------------------------------------- Hi! Please call me. We got an estimate a couple months ago and I called to discuss options 2 weeks ago. I left a message and heard nothing back. Just called the main line and the mailbox was full. Not sure how to contact you to discuss. read more

I have a cottage, built on a concrete slab just a few years ago, that had developed a leak during heavy rains. In the very heavy storm of March, 2018, the cottage had an inch of water over the entire floor. A specialist had tried to remedy the problem a year earlier but was not successful. I called Drainage Pros and they were confident they could fix it. They dug beneath the soil to the base of the slab, waterproofed the wall, and installed new drainage. The next several rainy seasons never had a storm that matched the one of March of 2018--until our 8 inches of rain over a two-day period in October of 2021. The cottage floor remained completely dry, so this was my final assurance that Drainage Pros had fixed indeed the problem. I recommend them highly. read more

I am a real estate agent and have used Rich for drainage inspections and repairs. Rich is reliable and a wealth of knowledge. Terri is a pro at setting up appointments that work for me and my clients. I highly recommend Draingage Pro's. Loads of experience and knowledge. read more

I interviewed 5 companies to install a French drain And sump pump. Rich The owner of Drainage Pros assessed my property. He was very knowledgeable and professional. He provided pictures and documents required for the homeowners association for approval. The crew was incredibly hard-working and left The property intact. I was extremely happy after this last big rain storm that my French drain was installed and I had no standing water. I highly recommend drainage pros. read more

ALL GOOD! Professional, effective, and customer oriented. Rich pays close attention, makes sure you're getting what you want, and is not out to get you with every little change that takes place. The work crews are just that - hard workers. Always there when you expect them....working hard and professionally...and not a lazy person among them. I'm confident I could have had drainage work done less expensively, but these guys are truly professional, and I have confidence in the end result - proven by what is see during this unusually rainy season: no standing water where there used to be, and good flows curbside. I'd go to Drainage Pros again in a heartbeat - no hesitation. read more

Rich and his team are the best. We were on a tight deadline to get some drainage work done to get our house ready for sale. It was the end of the year (winter time and I assume high season for them) and he was pretty booked up, but accommodated our schedule and had his guys work on weekends. The guys were neat, mindful of the plants they were working around and left the place as they found it. read more

Scheduled appt almost a month in advance 2-4 window. Was not sure about the $150.00 charge for an estimate but read the reviews and said ok. Got off work early to be here at 2 waited at 3:30 got a call from office asking about the her guy was there yet so said no he's not. She said she would call him and find out where he is. Rich called me 3:50 and said 30 min late so I wait another hr no call no show. So I call the office at 5 I guess it was time to go home no one answers. Wasted 3 hrs waiting for them got off work early. Terrible way to run a business complete waste of time. read more

I called Drainage Pros out to my home to give me a quote to install a channel drain in my patio along the back of my home to prevent water backup in front of my patio door. Keep in mine to they charge a fee just to come out to give a quote. Rich arrived 2 1/2 hours late. We walk to the back of the house Rich, wets down the patio then sat down and started his sale pitch. Telling me I wouldn't be happy just installing a channel drain that I had a type A personality, He was so focus on asking what my budget was, which I was not going to tell him . All he wanted to do is sell me on replacing the concrete with pavers at a cost of 16,500 to 18,500 when all I wanted to do is fix the problem at the lowest cost possible which was a channel drain with bottom outlets connected to a drain line below the channel. What a waste of time and money. read more

Rich @ Drainage Pro is beyond amazing. He truly goes OVER and BEYOND on all he does and is so detailed! I was able to learn so much from him and his guidance and expertise were priceless! I would highly recommend anyone and everyone to use Rich @ Drainage Pros. Their entire staff is superior! Sandy Shehata Realtor @ COMPASS read more

Rich and team at Drainage Pros are great! We had a time sensitive drainage issue in our side yard that required immediate attention. Rich adjusted the schedule to meet our requirements. The technician, Alberto, explained everything from start to finish and made sure the job was completed in an efficient, quick and beautiful manner. If you ever require a drainage expert to take care of drainage issues, Drainage Pros can get it done! read more

They wanted $150 just to come look. It would be applied to the cost of the project but for any big project i get multiple estimates, as do a lot of other people. So no guarantee I'd would select this company. So I could easily end up out $150. They were the only company asking for a fee. read more

If you have drainage problems, Drainage Pro is your company. Rich was always available for any questions I had during the process. My job was completed on time even with the rain we had. All of the workers we nice and professional. If I had any other problems with drainage, Drainage Pro is who I would call. They are who I recommend to all of my friends. read more

Rich took the time to come out for an initial quote back in spring 2018. I won't lie, drainage work is not cheap. Of the three quotes we got, Drainage Pros were the most expensive, but they were also the most comprehensive. We sat on the quote for a while thinking "well, it's not raining anymore, lets just see. Do we really need this?". Fast forward to July and we were doing some house work and found mold under our floors in our house. As we were getting the mold cleaned up I made a panic call to Rich as I knew instantly that we had to deal with the source of the mold and not just the remediation. (I'll mention here that we live on a hill, up hill from one house and downhill from another. I'll also mention we have some plants on the uphill side that never get watered and yet are thriving even in this drought. So clearly water is coming from somewhere and when it goes to those plants, it also goes right under our house.) Rich bend over backward for us to get a crew together quickly and start the work. These guys did an amazing job. High quality work, well thought through plans, and construction quality that I know will last for a long long time. I am very pleased that we went with Drainage Pro's and Rich and would recommend his services. When comparing quotes, at the end of the day you have to ask yourself, do I want it done cheaply or correctly? For us, it was easy, I said "i do not want water under my house ever again. period." read more

Rich is terrific and clearly knows what he is doing. His knowledge level is far greater than his competitors and he is passionate about his business and the industry (not "phoning it in" and making info up like some competitors). He is thorough and thoughtful, which is greatly appreciated these days. I highly recommend Rich and his company. read more

Rich, Alberto and their crew recently helped us out with an unusual need - a 70-year-old abandoned septic tank that had collapsed underground and formed a "sinkhole" in our back yard. We sent photos of the site and the limited access (no chance for heavy equipment). Rich stopped by to assess the situation, and quickly scheduled a crew to come out and manually dig out the old redwood box (about the size of a tall double bed six feet under ground!) and refilled and compacted the area with drain rock and soil. It was an incredible amount of hard work performed in two days by three men. They replaced our decorative rock on top, completed the job, and now the yard flows nicely and looks like nothing ever happened. Much respect for the work of Alberto and his crew. Contractors can be busy and hard to pin down, but it's nice to work with someone who shows up and does what they say they'll do. read more

Rich and team provided excellent, quick and kind service. I left a message for them on a Friday afternoon, not expecting to hear back until the following Monday. Rich called me back Saturday morning, concerned my pump was flooding the house or there was a bigger emergency. Bart came out and fixed our pump, cleaned out the well and provided me tips on how to keep it clean. The top of the well was an old wood fitted piece that we had kept covered with heavy pots so that children and or animals wouldn't fall in. I asked Bart if anything could be done to make a more sturdy structure. He immediately said SURE! I called Rich, he cut me a deal on the service fee since they were just out. A week later Bart came back and fitted a manhole cover for the well. He was quick, cleaned up, helped move our heavy pots, and showed me how to move the cover when we needed to get in. I have been worried since we bought the house that something terrible would happen with the previous cover. I can rest assured now that no children or animals will be able to access the well. read more

Before service by Drainage Pros, our duplex in Daly City experienced standing water under the house each winter. The project to install the drainage was a big one, but it has worked flawlessly each rainy season. Rich's team comes out every year to test the sump pump and service it if necessary. I can't say enough about the quality of the job, and satisfaction with the ongoing annual service. read more

Had drainage work done several years ago and have had no problems since. Very pleased . The workers were polite, professional, , and knew exactly what to do. . Rich did come by and check the work. Clean up was amazing. I did recommend Rich to friends and they are also very pleased. Now when it rains I can enjoy it without mopping and mopping. read more

These guys were just great. We had a French drain installed that required a 6-foot trench through all sorts of ground, including some that were cosmetic and required careful rebuilding after the trench was completed. They did it all with no fuss, no issues, and in remarkably little time. And all for a very fair price. Highly recommended. read more

In 2016, I had a serious drainage problem (18 inches of water in the sub area after a sump pump failure during EL NINO.) DrainagePros who installed a system around my townhome which included a sump pump to mitigate the ground water. Rich and his crew were wonderful to work with. But that's not all.....last weekend (Friday night) while out of state naturally, neighbors called to tell me that they heard an alarm going off in my garage. In a panic, I left a message for Terrie (4 or 5 times, I'm afraid) who called Rich who called me back and told me he and Alberto would get there to scope out the problem. Terrie has my undying thanks for answering the phone when she was on vacation. My son who was in San Francisco went to the house and turned the alarm off and unplugged the sump pump which Rich said was appropriate to do. Alberto did come to the property (observed on my RING doorbell!) to replace the sump pump. The professionalism and response of DrainagePros team is unsurpassed. I recommend them for any of the services they can provide. Rich thoroughly calmed me down during this second situation which was, I believe, covered by two add-ons in my contract which I would thoroughly recommend for peace of mind and for the protection of your property. Walnut Creek Resident since 1966. read more

Before talking to Terrie from Drainage Pros I was super overwhelmed and freaked out by all the alarming information different contractors have provided me as I try to navigate the muddy waters of drainage and foundation repair. Thankfully, she put things into perspective and squashed some misinformation. I appreciate her expertise, honesty, integrity, and transparency and look forward to potentially using them for my project. So far, the initial experience has been a comforting and refreshing breeze compared with some other companies I've been talking to. read more

Based on positive reviews on yelp we contacted Drainage Pros for our clogged drains. Although we had two other estimates, Rich explained in most detail what needed to be done to fix the problem. We felt comfortable with his expertise and he did not disappoint. His foreman, Alberto, and the crew worked tirelessly and kept the area clean every night. In addition to replacing our drains, Rich agreed to landscape our yard. Even though landscaping is not their core business, they did an excellent job. We highly recommend Drainage Pros and are ready for another wet winter. read more

Rich was very responsive to any calls/messages we made and was quick to give us information as we requested it. He and his crew were very professional and mindful of keeping the area they were working on tidy and safe. They completed a drainage project for us along with adding pavers to our patio - the end product looked great. We are no longer fearful of flooding in or around our property, plus have a beautiful patio for entertaining. We were recommended by a friend to use Rich for this project and have since recommended him to our neighbors, who are now looking to hire him as well. Would definitely use his services in the future for other drainage issues or even simply for installing pavers. read more

When the home inspector alerted me to the need for drainage I had no idea what the scope of a drainage project would entail. Thankfully Rich takes the time to educate clients in person and he provides a thorough estimate to refer back to project specifics. Other contractors I got estimates from did not even bother to take measurements or note project details on the bid. During the project Alberto (the foreman) and crew were great! The crew started work on time each day, kept the job site as tidy as possible and worked tirelessly to keep the project duration to plan. Communication throughout the 6-week project with Rich and Alberto was solid. This review is for a project completed in June 2016. I was so pleased with my experience that I'm hiring Drainage Pros for another project today which reminded me to post kudos about the last project. read more

Our experience with Rich and Drainage Pros was superior from start to finish. Our neighborhood in downtown Walnut Creek is notorious for poor drainage. I finally pulled the trigger after years of minor floods, leakage and failing sump pumps. From Rich's first visit, it was evident that he knew exactly what he was talking about. With zero evidence of any prior rain, he pointed out exactly where he thought the rain pooled and where it was likely entering under our house - and nailed it. The actual work phase of the project was executed in a timely and professional manner, on time and on budget. I'm glad I waited almost two months to write this review as we just completed a record rainstorm in the Bay Area and not a drop appeared where it had for so many years. I would highly recommend Rich and his crew - top notch work - top notch service! read more

Rich and Alberto really know how to solve drainage problems. They use quality materials, work hard, and charge a fair price. They are also very responsive. Use Drainage Pros with confidence. read more

I scheduled an appointment with Drainage Pros and Rick came out promptly. He was attentive to detailed and really knew his stuff. He offered multiple options for me and after the consultation, I felt confident in the work described. I waited and waited for an estimate - nothing. Contacted him and he replied that he'll get back to me shortly. Followed up 3 more times with no reply. So that's that - $150 for the estimate, got my hopes up, and delayed getting the work I needed as I waited months to get a quote that never came. I'm now back to square zero getting other contractors to come out. read more

Drainage Pros helped me with my house drainage problem a few months ago. I'm very pleased with their work, people are friendly and professional. I interviewed a few companies and drainage pros are the only one that offers five years no standing water guarantee. Will definitely work with them again in the further for other projects. read more

Subsurface and French drains is never what anyone plans. Our house was well built, but drains had succumbed to relentless invasion by redwood tree roots. December's 10 inches of rain exposed the inadequacy of our drainage system. Rich Mariani's Drainage Pro team was responsive from the first call. The assessment and bid were comprehensive, followed by a detailed contract that spelled out every stage of work. Rich's well-trained team worked diligently for 4 weeks. I could see every day that Javier and his 5 men were organized, careful, and hard-working. Rich made a detailed inspection every week, and the team responded to every item that he identified. Rich was never too busy to answer questions and concerns as the project went on. A critical stage is putting everything back together. Rich upgraded our sprinkling system where new valves were needed, restored our landscape lighting, regraded the ground around the house, improved the stucco siding at the foundation, and carefully replanted every shrub and tree. He brought in skilled concrete finishers to recreate our pebble-textured driveway beautifully. They sifted through pebbles to make sure they matched what we had. It truly looked like the pavement had never been disturbed. Finally, he put a rat-proof concrete layer over our crawl space. Our lower level always had the earthy smell of a basement. After his work, that smell is gone. Although we had not expected it from drain replacement, Rich left our home a better place than he found it. Robert F, read more

The rain has finally come and I'm just shocked with amount of water coming out of sub drain. This really confirms Rich assessment was correct! read more
