"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

"Dry Tech Waterproofing Solutions Not a stand up company. So much promise. The people were friendly, they got it done fast. At the time of write up, i told them the basement gets feet of water per day. I need a GOD level solution. Two sump wells were put in with a battery backup. The pumps ultimately failed due to a breaker tripping because they put two 10 amp pumps on a single circuit. The basement flooded since no one is actively living there to hear the backup pump kick on. This in turn fried the battery backup and the electrical components that were installed knee high. I try to leverage their warranty, and they wanted 300 dollars to replace a marine grade battery that got destroyed because the basement flooded and the backup wasn't waterproof. It isn't even water resistant. Its a plastic box that doesn't seal. Absolute garbage materials. The story changed from its the cost of the battery, to its the cost of the labor to fix what their warranty should have covered: A sub par in"

"AJ was quick to respond, gave me plenty of time to look at the project and had a vast knowledge to speak directly to my concerns. His solution for my basement walls was simple and reasonable. He did not try and sell me on unnecessary items that other companies tried to make be buy. His work crew were excellent. They were hard working, quiet, and very clean. They took care of covering everything up, hauling away all the rubble and even some of the collected junk in our basement. The job was completed in 3 days.

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Downingtown, PA

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.
