    Working to seal the shared wall.

    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.

    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.

    Soil compaction behind retaining walls

    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!

    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).

    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.

They also carved out a lovely hillside with custom stairs, a spacious terrace, and game trails perfect for enjoying the view. LEI works with YesPlease.Garden (YPG) who managed the design process and Fresh Coat Restoration who completed the new fence. The partnerships were well integrated and it felt like working with a single team. See my Google Maps review for more on YPG. We are very happy with our project and would recommend LEI because they were professional, courteous, reliable, and provided clear and upfront pricing. Documenting decisions in writing proved helpful for keeping everyone on the same page. Any problems we had were resolved fairly, such as correcting the direction of our stairs. Aaron is a man of his word but prefers to conduct most of his business through texting. We first contacted LEI and they promptly scheduled a time to visit our property with YPG to see what was possible within the budget we set out. We completed the design with YPG and LEI scheduled a time for the project demolition. A later approximate time for planting was set, but that was dependent on the availability of the various plants we had selected. Everything scoped in the design was completed within the budget and any add-ons we later requested were priced separately and fairly.

After deciding to remove our pool, we hired Aaron as the installer for our new landscape project, and we are so glad we did. For months, work was moving forward almost every day, from demolition prep and grading to hardscape, planting, irrigation, lighting, fencing, pergola installation, pebble work, and the finishing touches. The quality of the work was excellent throughout. The paver patio, carport, and front entry all turned out beautifully, and the plants, irrigation, and lighting were installed with great care. We were especially impressed by the rock and pebble work, particularly the dry creek and front mow strip. The mix of stone sizes gave everything a natural, detailed, and polished look that really elevated the final result. Aaron also has a strong eye for detail. He regularly caught things that needed adjustment, even when we had not noticed them ourselves, and he stayed focused on getting everything right. While there were some issues that delayed finishing the project, Aaron took responsibility and worked with us to make them right, which we truly appreciated. In the end, what matters most is that we are thrilled with the outcome. Our yard feels beautiful, welcoming, and complete, and we look forward to years of enjoying it.
