"I helped my daughter with this crawlspace encapsulation work on her house. I solicited 3 quotes and it was an easy choice to go with Basement Waterproofing Nationwide. From the initial inspection and quote with Tim, the financing and finally the work with Will and his crew, everything went well. They completed the job to my expectations, answered all my questions and kept me informed all along the way. They actually finished the job in 3 days instead of 4. I highly recommend giving them a chance."

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

"AquaGuard waterproofed our leaky basement in 2003. French Drains, Sump Pump, Concrete work. Not a drop of leakage since. Eliminated the dampness from the basement. Sealed the basement while working to prevent dust getting to rest of house and cleaned up completely when done. Professional work!"

"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"Wendell truly lives up to his Companies name. He can be trusted to get the job done right. I needed help quickly as our house was on the market and the record rainfall was taking a toll on our basement. Wendell had his team come in within the next few days after the initial consultation and waterproofed the basement walls. They did need to come back and secure a few leaks, but he took care of it immediately. I'm very pleased with the work they've done and would refer them to my family and friends. He also offers a 3 year warranty, which gives me peace of mind for any future needs."

"Juan and his team did another great job for us. They performed this necessary repair in a timely fashion and were very professional. They had to coordinate their work with the basement waterproofing people and they have no problem doing that. We intend on using this company for several other repairs in the future, and I would strongly recommend them!"

Basement Waterproofing questions, answered by experts

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.
