"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."

"Luis and his crew did a great job in handling a tricky concrete walkway removal and reinstallation of that same concrete walkway sections. The removal was required for needed sewer line repairs under the walkway but we needed to retain the existing walkway to be consistent with the rest of the walkway and home entrance. They were able to do this quickly and with great care to maintain the look of the rest of the walkway and entrance. It was job very well done."

"We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them."

"We had a great experience working with Step Up Concrete & Construction and would recommend them to others as well as work with them in the future if we have additional concrete projects down the road. We requested quotes from several companies and Step Up was the fastest to respond and complete the estimate process. They were knowledgeable about our options for addressing the reason our old asphalt driveway was failing with low spots and a pothole. It was an easy choice to work with them after the estimate experience. They were excellent at keeping in touch to get the work scheduled and to make sure everyone was on the same page about what we were looking for with our new driveway with an extension on the side. The work was done within the timeline explained and the crew was very pleasant to interact with. We are very happy with the way our new driveway looks and with the smooth experience of getting it done through Step Up Concrete & Construction."

"I originally contacted Strong Foundations to check the integrity of the house foundation for root or water damage. Since I've been in this house 15 years I decided to go ahead and do a full home inspection instead. The inspection was thorough and professional, of a much higher quality than I've experienced in the past. Response to booking request was quick and flexible. Within 24 hours of the inspection I received an 87 page report with photos and maintenance recommendations. I passed on his contact info to friends that are house hunting and they say he has saved them from two potentially disastrous purchases and are very grateful I shared this great resource with them."

"Highly recommend Matt if you are looking to retrofit your house. His work is of the highest quality, he tailors his services to your needs, his fees are competitive, and he was excellent to work with. As a quick background, I work as an architect, so I'm familiar with building trades and permitting in Seattle, and Matt has got this thing figured out. If your house is on a CMU foundation, especially, Matt is your guy. There's a good way and a bad way of retrofitting CMU foundation walls, and Evergreen Seismic is one of the only shops in town with the capability to do it the right way. Matt takes the time to understand your needs, and can customize his approach to save you money and hassle whenever possible. Very happy with the quality of his work, I don't think you could do any better than to go with Evergreen Seismic for your retrofit."
