"They did it right & quickly. However, the price quoted to me was no where near the final price. They said they installed a secondary pump which added $1450 more! I don't see how a 2nd pump cost more than the primary one. Don't like getting bids over the phone without seeing what needs to be done."

From the first phone call to the annual maintenance offered, our customers have peace of mind knowing we’re there with one mission – to repair, protect and improve their home.

"JES Foundation Repair (A Groundworks Company) proposed a solution for my basement wall reinforcement, and waterproofing. I accepted, and a date was set. They did not show up and it took 8 phone calls and 24 hours to find out that they weren't confident in their proposal. They increased the scope and added 50% to the cost. Stupidly, I signed again as time was wasting and I didn't want to start over with new vendors. JES completed the work while I was out of town. When I got back, there had been heavy rain and there was more water in my basement then I had ever experienced. I contacted my rep via text (impossible to get through by phone as he always was in "Training" when I called). His response was " That doesn't look good, I'll make some calls". I had to make the calls. JES sent several new employees out and they proposed additional work at ADDITIONAL cost. Unable to get satisfaction from mgmt. Had another foundation company finish the job. Do not use!"

"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. "

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Middletown, DE

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.
