"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 reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"We found Basement Waterproofing Nationwide to be highly ethical and very knowledgeable. A little over a year ago we had BWN perform some basement waterproofing. We were delighted with the work and the options presented to us as well as the speed with which it was done. This summer during the very heavy rains, we had some water seep into the basement so we called for an evaluation. As it turned out, the rebuild contractors (which we had opted to contract with a lower price provider vs. using subs hired by BWN) never communicated to us that the newly installed sump pump required an electrician and that it was not hooked up. This house is inhabited by tenants and we are not in the same state, so it's hard to tell where the communication breakdown occurred. Basement Waterproofing Nationwide's service rep however was extremely professional and helpful in delivering this bad news. He also checked and was able to confirm that the waterproofing was still good. He made a few suggestions like letting us know that he noticed where the drywall had been replaced that the outlet plates were never reinstalled. I also had some questions about the contract and he was very helpful and had the office fax me the pertinent info that same day. Lesson learned for me was that it would probably have been better to let BWN hire the contractors for the rebuild esp when you are out of town and unable to oversee. When there are heavy rains in the area like Baltimore had in July, it might take a few days for them to process the volume of calls especially if the nature of your request is minor. But they do respond. They are extremely professional and they stand behind their work."

"Jeff came to give us cost estimate for fixing our basement leaking issue. He was one of most knowledgeable professional I ever meet during my initial move in to new house. He explained why it is leaking and what we can do about it in very detailed logical explanation with clear diagrams to assist my understanding. Jeff said to fix these issues if it still leaks than come back for further assessment. It was great help, and I can really work on source of this problem now. I will never use any other waterproofing company other than All Aspects Waterproofing, LLC."

"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 questions, answered by experts

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

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.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
