"We had pest and ant problems in a 1930’s home we recently purchased. It had been vacant for some time. Part of the solution was to redo the crawl space. Andy Construction gave us a very reasonable quote for removing what was there and installing the vapor barriers, replacing spotty floor insulation, sealing cracks and new access doors. The crew was courteous, on time, and left no mess. We haven’t seen a mouse since and the ants are getting under control. Our floors and home are so much warmer! We heartily recommend Andy’s Construction. "

"Let me start off by saying Im super impressed with the install crew Malik, Andy, and Brian. This crew is very professional, personable, and works REALLY hard! Please be sure to convey this to whoever is in their up-line as they each deserve kudos for being great employees and representatives of Groundworks. I was also VERY pleased with our estimator Zaire, he spent a lot of time planning and adjusting to our needs/wants for this project. Very communicative. I highly recommend Groundwork?s! "

"Overall a good experience. We hired ACS to take down and rebuild a brick pillar supporting our front porch. Gary's crew was excellent. Although they only spoke Spanish they were helpful and did a good job communicating as much as they could about what they were doing and/or had done. We're very happy with the end product. Gary stayed true to his quote and the contract price. The project was more involved than I expected, but they came through and completed it on budget. My only complaint is that Gary was hard to get a hold of at times."

"?? SCAM ALERT ? BEWARE OF THIS COMPANY ?? All these 5.0 reviews are fake Do not hire this company. They took my money and then disappeared. They have no integrity and will lie and scam to get paid upfront. Before you even consider contacting them, review the complaints filed against them in Washington courts ? there are multiple cases. My experience was horrible. They were paid 50% of the contract upfront, yet never started the work. Do your due diligence ? this company cannot be trusted."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Seattle, 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.
