"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"The work performed was incredible. AJ and his team are real pros. The cost for all of the work they performed was more than reasonable. AJ came out for an estimate and explained the work he was going to do and gave me options on what different things he could do to help me out. He kept my wife and I in the loop every step of the way during the project. In addition, the crew didn't rush the job. They made sure the job was done right. Before the work was performed our basement would flood very easily when it rained. After the work was performed it rained and the basement was bone dry. This was a huge relief. Not having to mop up water every fifteen minutes was wonderful. Our sump pump doesn't run half as much as it used to. Basically, my wife and I are thrilled with the work performed and highly recommend AJ and his team to anyone

Basement Waterproofing FAQs, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.
