"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!"

"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!"

"They came in and put plastic on the floor and kept the door closed as as much as possible thus not letting heat out of the house. All the work after went smoothly i.e. quick and neat. Everytime I had a question, Andy stopped and answered every concern we had. He also guaranteed the water clogging wont happen and asked us to contact him on direct line if ever we have a problem. At the end, on request, he also explained to us where and how things work and where the water will go in future. Time was scheduled at 10 am. Andy and his crew came 1.5 hours earlier than the expected time without prior information which caused me to get up and rush to the door half awake. That was the only complain I had."

"David and crew did an excellent job repairing the staircase going into my basement. It was rotted and water was simply going down the stairs and into the basement. They shored up the walls and installed pavers and a drain system to redirect the water so it does not get into my basement. Excellent job."

"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

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
