"We had a basement waterproofing issue. Shopped around a couple of companies. With the best rating on google, and with good reason, Best Buy Waterproofing was our choice. Rob was knowledgeable, diligent, patient and open towards our questions and concerns. Best experience I had with any company rep to date. He came out twice to our place (once the first time to look at the issue, second before he took the work to make sure we all are on the same page.) And then he was there before the work was started to make sure all of us were on the same page. The crew that came out (Darwin, Juan, Raul, Hammie, Chilo) were very careful about their work, respectful, and meticulous. They plastic sealed the work area to prevent dirt, and broom cleaned the area after they were done. Even after the work was done and the transaction was completed, Rob came out to check the work and to make sure it was up to his standard. He olso brought with him the mold treatment up on my request and took care of that as well. Thank you Rob! I highly recommended Best Buy."

"I thought my husband and I would contribute to Alex's reviews since we spent time with Jose and his team for the 3 days at Alex's house. We were amazed at how much attention was taken to ensure all our furniture and belongings were covered to mitigate dust. We are so completely satisfied with the dedication and expertise of Jose and his team. They left the basement in the best condition it was ever in. Very neat and clean, a great looking job. Kudos multiple times over for the finest production job we've seen in a very long time. They installed the interior drains and sump pump as well as a dehumidifier. No more dark, dank basement. It was an excellent experience. Thank you, Lon, Amber and Jose and team. Also a thank you to Jack Roadcap who recommended Lon to us. Warmest regards, Mary Ann Pinamonti"

"In 2007, I had the entire basement retrofitted for drainage as I was having some seepage problems in certain areas. Another waterproofing company based in Glen Burnie worked on it, however, when it came to the basement bathroom they didn't replace approximately 11 feet of pipe near the vanity and toilet. Guess what, after 6 years, that area of the bathroom started getting flooded with water every time it rained. It got to a point where I could not tolerate the nuisance that we had to put up with and tried calling the original company but they were out of business and I was left with no option but to hire another company to do the 11' of pipeline. Ameri-Dry staff came over and discussed with me the different options and we agreed upon a price. Mike and his staff worked very well in the more efficient manner on the day of the repairs. They completed the work well and on-time. It has been over two months and we have not had the recurring problem with flooding of our basement bathroom anymore. Thanks for the good service and work you did!"

"Steve Norfolk (owner) returned my call quickly, came out to inspect my basement within 24 hours and gave me an estimate that was significantly less then another "national" provider.  He got me on his schedule promptly and his crew came out on time, performed the work, cleaned up after themselves and I have not had a water problem since that time.

Basement Waterproofing FAQs, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

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.
