"Gauge is a Representative who puts his Clients first. He reminds me, of a younger me.

We are not a big company that you have to go through all the phone calls. Owner Andy Zhang will be the one to answer the phone, provide you the bid, and supervise and inspect the work before finish. We are so confident in our work, quality, and over all experience that we don't need any money down. Our customers don't pay us anything until the work is done and customer is happy! For a house on the market, in most cases, we allow owner pay the full bill through escrow at closing. We pride ourselves in treating every customer with honestly.We looking forward to hear and serve you soon!

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.
