"They fixed two leaking cracks in the basement exteriorly in May 2019. Also, they regraded the patio so that the rain water runs away from the house. I am happy with their works. I am glad my basement is dry now. Thank you."

"Basement Waterproofing Nationwide did excellent work in a timely and proffessional manner for a reasonable and appropriate fee. They said they would complete the work in 1-2 days and were done in one day. They were very careful and left things neater than they were before they came. We have used them before with great success and would use them again. So far, the problem we had, water in our basement, has not recurred, and our basement is bone dry. Tnank you Basement Waterproofing Nationwide."

"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."

"Alex from Lux, gave me very helpful advice and he concluded that his company’s services were not warented. Trustworthy, honest advice, and he answered all my questions thoroughly with visual and verbal explaination. Lux is a company I would recommend and use in the future. In my personal opinion, Alex saved me $10-30k in waterproofing. He said that I did not have a moisture issue in my basement and he gave me 3 things I could do to make my basement environment safe and sound for the future. A different contractor came in and gave me a free estimate to put a sump pump in for $7k and then I’d need to finish my basement for an estimate of $20k. Alex from Lux, said I had a dry foundation and that my mold on my vinyl was likely a cause from a leak years ago from my washer or my dishwasher a level above. I truly felt that Alex was truthful, helpful and Honest. Go with Lux if you seek an honest opinion and company."

"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

"I hired Alex three years ago to stop the water from coming into our Florida room. After going threw four other contractors he was the only one that took care of the problem. Now we hired him again 7/19/18 to take care of the water coming into our basement. He sent out Tyrik, Corey, Nathan, Casey J;mony, Cody and Joe. They were very professional and and kept informing my husband of the progress they were making. At the end Tyrik explained everything they did and told us if we are not happy with any of the work they will fix it right now."

Basement Waterproofing questions, answered by experts

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.
