"Joel and his crew did a fantastic job. I really appreciated Joel's professionalism and thoughtfulness when he evaluated the problem and formulated the most effective solution. The work was done in a timely and efficient manner. And the best part it is, that I no longer have water in my basement despite many periods of very heavy rain. I also had Guardian waterproof the basement in my former house with similar positive results. I recommend them to the highest extent!"

"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!"

"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."

Basement Waterproofing FAQs, answered by experts

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.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

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.
