prompt, hard working team, thorough job including after job clean up. after the payment was made, reached out to Wu Construction for a favor - to take some pictures of the crawl space after the project. No problem, they sent a foreman to do just that. It has been a great pleasure working with them.

French drain installation along a retaining wall (75 yards). Thomas who handled the sales end of things was friendly and responsive. The crew showed up on time. They were hard working and receptive of customer feedback. They first removed the ivy that was obstructing the work area and then completed the trench on day 1 which uncovered some of the unwelcome water sources. A legacy footing drain was plumbed directly into the main french drain pipe. Perpherated pipe was dropped in on Day 2 followed by river rock, catch basins, and 3 ft dry well installation. Cleanup was done thoroughly. I would hire them again in a heartbeat.

Greg and his team were wonderful to work with from the start. It's going to improve our house and our life to stop having water in the basement everytime it rains. We can finish our basement and actually use the space now! Thanks for being so easy to work with and delivering a quality drain system.

I am extremely happy with with Wu Construction! From start to finish it has been a very pleasant experience. First, I send a frantic email after heavy rains to which I received a quick and reassuring reply - on the weekend! Next Greg came out to quote, provided a good price and was able to get the work scheduled for me on the spot for only a week later. Thanks Greg! Today the technicians arrived right on time, were very professional and did an amazing job. I kept peaking outside to see what was happening and I could tell they were executing the work with great care and attention. The quality of the work exceeded my expectations. Also it was discovered midday that more work was needed than originally thought when one of my downspouts was unearthed full of roots. I appreciate that they were able to accommodate the additional work and still complete everything in one day!

It went very well. Greg was a great guy. In the initial consultation we missed a wall that also needed a drain due to the crawl space, and his lovely crew came back and made it right. Greg was also always available to answer my many questions and made sure I was completely comfortable in the work. This is the first time I have had a dry basement as long as I have owned the house! I cant recommend highly enough.

Greg was prompt in coming to view what needed to be done and quickly assessed the best way to prevent storm water from entering our garage. He gave me a very fair bid and stuck to it. His work crew, Young and Jasper, were here right on time and worked hard all day until the job was completed. They didn't waste a minute, doing exactly what they said they would do. Their final product was excellent, much better than what I envisioned it would look like. Their work will resolve our problem (now I just have to keep things clean). Thank you for a job well done! I certainly will hire Wu Construction again if I need any services they provide.

Our experience with Wu Construction was awesome. We had water coming into our basement, gave them a call, and from consultation through installation, they were one of the most courteous and professional contractors we've dealt with. Their work is quality, prices competitive, and communication was excellent. Would recommend them to anyone with water issues.

Better than I could have asked for. They came up with a GREAT solution to my basement leaking issues (I had a river in my basement last winter) thus far this fall not a drop. His option was faster, cheaper and more effective than the other 3 companies i had bid the job. I could not be happier!

This was the absolute best experience with a contractor I have had in the seven years years of owning my my home here in Kenmore. Thomas was not only knowledgeable but conscious of what my choices were and was willing to offer fixes that were not the most expensive but the most effective. His crew was right on time worked diligently all day and cleaned up before they left. I only wish there business did more things I would hire them in a second. I would absolutely recommend this company. Thanks you !!

Excellent work, all around! The crew was hardworking, and the work performed has stood the test of time. Three years ago, Wu Construction expertly installed a full crawl space perimeter footing drain, brought in drainage gravel, and installed a 1/3 hp sump pump. Also installed a 6 mil black vapor barrier, checked and sealed alle entry points to prevent rodent entry, re-installed all loose inulation and replaced heat duct insulation. The crawl space has remained bone dry, and we've had no further issues with moisture or rodents.
Description of Work: Crawl space had poor drainage, often had small pools of standing water, and was prone to pests. Hired Wu Construction to improve drainage so that crawl space would remain dry and clean.

Wu Construction did an excellent job for us. Greg estimated what work needed to be done and we scheduled it as quickly as possible. The crew was on-time, very efficient and did a really nice job keeping things as clean as possible, which is no easy task when repairs are done to a wet & muddy foundation area. A full interior perimeter drainage and sump pump system was installed to eliminate standing water in the crawl space. The crew also removed all old floor insulation and installed new R-30 insulation. The crawl space was completely cleaned up and a new vapor barrier was installed. Everything was completed as agreed upon - all at a very fair & reasonable price. The crew even installed a permanent access ladder to the area so it would be easier to get into the crawl space area. I'd highly recommend Wu Construction for any drainage or foundation work needed to your home or business. Greg, the Estimator/Scheduler and Thomas Wang, the Construction Manager were a pleasure to work with. They kept us up-to-date on everything and were true to their word. I look forward to working with them again, as needed.

We had a fantastic overall experience with Wu construction. Victor was extremely responsive and communicative. Returned my initial call immediately and came out to evaluate our project the same day on a Saturday. He was very conscious of not doing more work than was necessary to achieve our goals and very focused on the quality of his work and the satisfaction of our experience. He gave a fair quote quickly and scheduled and completed the work in less time than he promised. He continued to be available and responsive throughout the process and his crew were on time, were respectful of our property and did great work efficiently. Victor came out to personally review the completed project with me, again on a Saturday, before receiving his payment. We couldn’t be happier with their performance in every aspect. I only wish he did more than just foundation work!

4.5 stars overall for removal of concrete slab/stairs and pouring of new 10' long, 4 foot deep foundation wall. Result was excellent. Crew was considerate and trustworthy. It was expensive for me, but cheaper than the other bids I got. Communication was not great over email. There were a number of times I wasn’t replied to at all or got a partial response. I let them know and they said they’ll work on that. I recommend communicating via text instead which worked much better.

Very fast response time, texting is very fast. crawl space needed drainage, insulation, clean up, new vapor barrier, and just entire remediation. They did everything as promised and passed inspection. Even though it took more work than anticipated, they stuck to their estimated price. Very impressed.

Foundation Repairs - We had dry rotted wooden posts due to concrete pads being buried below the dirt. Wu Construction replaced the posts/ piers and placed new concrete pads on top of the existing to raise them above the dirt. I had some questions and Victor Wu followed up with me. Victor is very professional, honest and fairly priced. I would recommend them to anyone who needed these services as well.

Wu Construction was hired to repair and improve the water proof problem of my house. The contractor, Mr. Wu has designed a whole package project that cost me 200% higher than others. His cost was ridiculously high but I followed his advice to the letter and have paid him a total of $146,000.00 and it came with a ten year warranty. Later I found out his expensive work was totally unnecessary. What was worse is that none of his work does the job. His entire work failed at the first drop of rain. Right now water is actively leaking everywhere in my house. After many repeated requested by me, Mr. Wu refused to come back to do anymore work. I am going to file a lawsuit against him for $200,000.00. Just look at his past Labor & Industries Record, there were two lawsuits against him and his company within a year. The first one was settled after Mr. Wu paid the other party big money in compensation. The second lawsuit is still open.

Wu Construction was hired to solve a water/drainage problem in the downstairs. What they did, didn't ever solve the problem, they made the problem worse. No one that did the work at the house spoke English so I couldn't even discuss anything with the workers. Instead of diverting the water away from the house they Funeled the water under the garage so the garage was sinking. They put down spouts back on the house backwards. They put in a sump pump that was not electrically up to code & was determined to be a fire hazard and it was tied into the wrong drain line. I filed a lawsuit against the company. Through the depositions I learned that the workers they hire have NO formal training. Victor Wu is the owner of this company.

It went fine. The team was very hardworking, and did an incredible amount of work in a single day. They cleaned it all up well after they were done, including replanting several plants that they had to remove for the work. Their pricing was very competitive vs. competing bids but I remain astonished that anyone could get that kind of money for a single day's work with five men. It is what it is, isn't it.
