"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

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
