"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"Contacted Mark within 3 days he was at my home and providing a detailed quote. Might seem small but he was the only one out of 4 contractors who actually measured the space to provide an accurate and detailed estimate. He while discussing what I wanted with me made many recommendations and even mentioned ways to get the job done but at a lower cost. He had the estimate to me within 2 days and it was super detailed and broken down with 3 different ways to complete it. He was on time daily as was his crew. Work areas were cleaned daily. He closed up a broken window for us, redid a dirt floor with drainage and concrete, repointed and waterproofed our basement foundation, ripped out and fully replaced basement access stairs. He even noticed a window that was broken we didn’t and closed it up for no charge. He added a drain to the exterior steps at no charge wasn’t in contract he just knew it was needed, the steps he replaced had asphalt around them and he even repaired the asphalt at no c"

"Mr. Aponte is a true craftsman and professional. We needed a bedroom ceiling replaced and window framing, trim work done. Mr. Aponte reached out quickly and was able to visit us for a quote in a short amount of time. His pricing was very fair and he had a very creative solution to our problem. Mr. Aponte was an excellent communicator both on site and by phone. He always showed up exactly when he said he would. It was very much appreciated! Our ceiling is absolutely perfect. Now, you can’t tell that any work was done at all, and I am pretty picky. His craftsmanship is incredible. He also pointed out some problems that a different installer had made which allowed us to have our window re-insulated and waterproofed. That will save us so much money in heating costs and potential insect, water damage—he has a real heart for his clients and wants to make sure their house is perfect as possible. We will be hiring Mr. Aponte again for additional projects very soon, thank you so much!"

Basement Waterproofing FAQs, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.
