Groundworks specializes in helping homeowners with their residential and commercial foundation repair, basement waterproofing and wall repair, and concrete repair needs. Our top priority is providing high-quality home repair solutions and personalized service across the Seattle area. With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your foundation.

"From consultation to completion the team at Groundworks handled our foundation repair with care and professionalism. Matthew came to the house and stayed to answer every question and explain every detail. He took the time to complete a bid while onsite and walk us through the process. (BTW their permitting department and financing through GreenSky really helped!) When the work started the first team of Alex, Iuni and Luis, were exceptional (they pier leveled the footing). We got texts the moment they arrived at the property and they got right to work, completing their part right on time. They worked as quietly as possible and kept us informed of the progress. The second team for foam leveling our slab and led by Daniel, got it all done in part of a day. They were also courteous and even helped move furniture. When the work of both teams was finished Alex, the foreman, walked us through an inspection and answered all our questions. Finally, Matthew circled back at the end and made sure"

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