"I needed to address a problem in one corner of my basement before an appraiser came in for a refinance that was in process. I was very appreciative of the companies that responded and fit me into their busy schedules on very short notice. Jason from A Action Waterproofing came by to give me an estimate for basement waterproofing. Two days earlier another company quoted $5,200 -- they would dig up a large bush and 2 smaller plants I had had for years to put in two protective layers (one plastic, one asphalt) for my exterior basement wall, then replace the dirt and mulch. At this point, I was just hoping for a lower quote. Jason let me know 3 hours before his scheduled arrival that he would be running about 1-1/2 hours late because he needed to take his daughter to an appointment, and asked if that would be OK. I certainly respect anyone who puts family first, so it was not a problem. As soon as Jason arrived we went to the basement. He said water was not leaking in and there was just discoloration on the floor with some on the lower wall. All that was needed was to clean the walls, apply hydraulic cement where the floor meets the wall, then paint with DryLok, and I could do that myself. I already had a can of DryLok that had never been opened. He said there was no damage to the interior and exterior walls. He did that during heavy rains there was one location where the downspout from my roof connected to the drain pipe that left my property where water could be released onto the ground, which should be addressed. I was so happy with his diagnosis that I wanted to pay for his call, but he refused. I'll take care of this before the appraiser arrives end of the week. Now just need to see what the appraiser says."

"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."

"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!"

"I just wanted to take the time to say thank Aquaguard for the many years of professional, responsible service and also for your recent service at my home. I have had both sides of my basement waterproofed, sump pumps replaced, and then also had them secure a foundation leak in the basement wall. All was done professionally, timely and courteously. Most importantly, Aquaguard has always promptly supported their guarantee and followed up with any problems that occurred over the years. I have referred this company to many friends and family members who also have been very pleased with the quality and professionalism of their company. There have been many friendly, courteous technicians who performed the work at my house but I wanted to give a shout out to Jason, who goes above and beyond amazing customer service. When he arrived many weeks ago to check on a foundation question that we had, he assured me that it was not a major problem but that he would return to fix the cosmetic work. I had forgotten about this issue because of the holidays but was pleasantly surprised when Aquaguard followed up with a phone call to schedule an appointment for Jason to come out to perform the work. Again, he called, arrived promptly and did a wonderful job completing the work. Thank you for your years of service and especially for the peace of mind with waterproofing at my home."

""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

"We had a wet basement, so we had foundation work done, and a sump pump installed. The work was done in March, but we have waited until well into the rainy season to submit this review, so we could be sure there were no further water problems. Dan, Tony, and the men who assisted Tony were excellent! Dan told us the work would take four days, but they completed it in three. They dug up a small mountain of soil in the backyard while working on the foundation, and their clean up job was very clean. They also took special care to protect belongings when installing the sump pump. Thank you."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Bethesda, MD

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.
