We offer 15+ years of experience in the Foundation and Basement Waterproofing industry. We've established a solid reputation serving residential homes in the greater Philadelphia and surrounding areas. We are committed to providing a personalized service for each individual project we take on. We look forward to building strong, long-term relationships with our clients..

"This company customer service skills and communication are horrid. I had no problem scheduling an appt for someone to sell me on their business but they day the work was to be done, I had to call them 5x for ETA checks on their techs. They were supposed to arrive between 9-9:30am and did not arrive until 1:15pm. Each time I called about the tech ETA, I was told by the receptionist that they would check and call me right back, they never did. The 5th time the receptionist said the supervisor of the techs said they were dispatched to my location early that morning, but he does not know where they are or why they did not show up. The receptionist called back later to say the techs should arrive by 12pm but they did not arrive until 1:15pm. When the techs arrived, I found that their supervisor told them to do a job prior to coming to my location. I was supposed to receive a lifetime warranty for the work done and after 4 calls I still have not received it. Poor customer service."

We are family owned and operated since 1952, provides home repair construction services in Delaware, Montgomery and Chester Counties as well as New Jersey and have been providing residential and commercial renovations and remodeling to the surrounding community ever since. We specialize in basement remodeling and conversions, windows, garage doors, fire and water damage, and many other reliable contracting services. Let our reputation of doing whatever it takes to get your job done on time, on budget, and to your satisfaction give you peace of mind. Our engineering background means we accomplish what others say is impossible. We always focused on our client goals and delivering high value outcomes.

"In all cases he put in what he wanted, and in all cases it was a lot cheaper and WITHOUT RECEIPTS . We were charged for the upgrades but did not get them (Refused to provide receipts,even when asked repeatedly (we have texts from him saying NO RECEIPTS, NO RECEIPTS! NO RECEIPTS!). They cut a huge hole in our garage ceiling for I have no reason why. Also one in the bathroom closet. Bought cheaper toilets than the ones we chose. Became very annoyed with my wife, said he would return them but didn't and installed them anyway. This we know because they still had the identifying sticker still on it. They put the wrong flooring in. We picked one that would match the existing hallway floor. It was an upgrade so we were charged more money and they put in the cheap floor anyway. The bathroom tub was supposed to be a nice tub to go with the expensive tiles we picked. They put in the cheapest tub they could buy and refused to take it out. They then put non slip silicone strips on the bottom that makes it look even cheaper. We came to find that the reason for the strips was to hide a chip that was there. They were repeatedly told we wanted SLIDING shower doors. They purchased the cheapest one they could find with a door that opens out. We asked for power flush jet toilets. They purchased watersense toilets, got mad when we told them it was not what we wanted. Finally said they would return them but put them in anyway. They left the water sense sticker on them is how we were sure. . There were cabinets put in without spacing and as a result the doors and drawers wouldn't open without scraping against the one beside it. We had to replace and buy new ones. The countertop was installed without having a plumber come in beforehand and set up the drain, so now installation of a garbage disposal is impossible without removing the countertops and cabinets. In both bathrooms, the wall niches have mostly gray and dirty white half inch thick threshold pieces to box them out (our bath is brown based) that were cut short at the ends, then filled with gray grout as filler. They couldn't look more horrible. They were also asked to put in white grout to match the brown and white of the bathroom tiles. They put in gray. Towards the end, we asked for proof of license to contract along with receipts. They refused. We told them not to continue work until they could give us receipts and proof of license. The very next day, I came down to find workers there scrambling to finish the job they had so far taken them two months to do. We received numerous and lengthy text messages from them cursing us out, accusing us of sexual impropriety and calling us foul names until we finally had to called the police. Succinctly, this company and the persons we dealt with, Perry Panaccio and his brother Al Panaccio, are a nightmare and not people you ever want have do anything for you! I am seriously considering suing, which I have never done...it is that bad!"

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