"The system was installed so that the pipes were pitched away from the sump, the pipe from the sump outside leaked back into the basement, and the exterior drain wasnt dug to grade so water backed up towards the house. When contacted about the issue, dryzone sent out a tech who confirmed every issue. The company then refused to fix anything without a second opinion. A month after I filed a chargeback, the GM called to "apologize", and made it sound like he wouldnt contest the chargeback, but offered no remedy to the situation. He then contested the chargeback and lied on the chargeback rebuttal. Eventually they settled for a partial refund. Terrible company, dont recommend."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Westport, MA

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.
