"Insulation Co stood out far above the other two bids we received. 1. RESPONSIVE – They answered calls immediately or returned them within 30 minutes and always followed through on commitments. 2. EXPERTISE – Guided us through attic and crawl-space insulation options, clearly explaining tradeoffs and demonstrating deep knowledge of building codes. 3. REBATES – Proactively estimated the rebates we’d qualify for and connected us with their utility company contact for verification. 4. EFFICIENT – Used public records to pull floor plans, delivering a highly accurate, itemized bid without needing a site visit. 5. TOP-NOTCH CREW – Their six-person team arrived on time, did outstanding work, and even sent us photos of the completed job. Highly recommended!"

"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."

"I have a 1906 cottage in N Seattle, with an old porous foundation. Water came into the basement for the first time in 20 years. Another contractor bid the job at $12,000 after 3 site visits and almost a month. Andy came out to the house the same day I talked to him, and estimated the same job at half that price. He followed up with questions, asked about making another visit, came out again and saw that the drainpipe was disconnected at the top of the area being flooded. 75% of the roof's water was pooling against the house. He found a ladder and fixed it and isn't charging me a dime. So, no French drain, no Delta drain, no foundation treatment, no 50' of trenching, no $$$. Andy was timely, reliable, did what he said, and knows his stuff. He was a great communicator, and I feel so so lucky to have found him."

"This company is built internally the right way. Extremely professional and everything is in house. I repeat...IN HOUSE. If you have ever dealt with a remodeling company that employs outsourced labor, it can be a mis-quote nightmare. Other companies pointed me to handy men for this job not realizing I might need or want more than that in the future. Thank you"

"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."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Bellevue, WA

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
