"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."

"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."

"John the owner was very professional. He explained all aspects of the waterproofing work that was to be done. Any questions we had, he answered so that we understood what was to be done. He was respectful and pleasant during the entire process. When we left messages needing to speak to John, he was prompt in returning our calls or texts. John's crew was also professional and resp0ectful. They were thorough in performing the waterproofing job as John had explained it. The work was completed within the timeframe. The crew did a great job on the waterproofing as well as cleaning up the areas. We are very pleased with the completed. There has been an extremely heavy rain for an extended period of time since the work was completed. I can honestly say the water problem is no longer an issue--basement is totally dry. We believe we made the best choice in choosing John's company, Brother's Waterproofing, LLC, to do the work,"

"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."

"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."

"The team arrived on time to do extensive work on my basement floor and walls and outside underground drainage issues. They worked tirelessly all day to remove old concrete, lay a new pipe system, pour new concrete, install sump pump, and seals. They prepped the walls and sealed and painted with Loxon paint. Radon seals were included in the redone areas. The outside work included installation of a new underground drainage pipe with pop up exit drain. A rubber membrane was installed behind the house siding. We?ve had several days of heavy rain since the waterproofing work was completed and the basement floor and walls have remained dry. We recommend Basement Gurus to other homeowners experiencing waterproofing problems for dependable and satisfying solutions."

"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."

"Two waterproofing companies visited before John with Always was scheduled to visit, and both gave me a quote to dig trenches and set up irrigation. Neither of the first two noticed that my issue is primarily a leaky pipe! A much easier fix that waterproofing. Thanks to John for noticing, and for being honest. If he had not caught that I would have picked from the three. Now if I need waterproofing I will call Always first."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Gaithersburg, 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.
