"Job was promised to be less than two days. The crew arrived at the time agreed on and was thorough, covered walls not affected by the work and were finished by the end of the morning. I will recommend AA Action to anyone in need to basement waterproofing, crawl space improvements and related items."

"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."

"Marketing representative Christian Abrigo explained all aspects of the benefits of encapsulation to prevent and remove mold and the associated odors in my large crawl space. He explained the technical procedure for installation. He answered all my questions about the safety of the product and provided a safety data sheet and references. He was a great guy who went beyond the call of duty to make sure all my questions were answered. Chris was knowledgeable, pleasant and enthusiastic. The installation foreman was also very experienced and knowledgeable. He answered all my questions on arrival and used tarps to cover all the flooring. There was no mess in my house and the install was not invasive or infringing on daily activities. There was no residual odor or unpleasantness after completion. My house and the crawl space were neat and tidy after the installation. Most important, the smell of mold was finally gone from the room above the large crawl space. I highly recommend NV Waterproofing and will use them again for waterproofing in my home. Photos can be provided by Chris of my crawl space before and after as well as other projects so I have not provided pictures with this recommendation."

"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!"

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"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."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Washington, DC

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
