"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."

"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."

"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 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."

"My husband and I are looking to re-do our basement and install new flooring. We were worried we had leaks/water problems in the basement and scheduled an estimate with Always Waterproofing & Concrete Services to see what the damage is and what we'd have to save up to pay for waterproofing. Jonathan was our evaluator. He was so helpful and focused on assessing the problem over making a sale. Turns out we may not even need waterproofing but instead better ventilation! He advised us that because he didn't see any concerning spots, we should first take up the sub-floor so we can really see what is going on underneath as far as flooding etc. Great customer service, wonderful attitude. You can tell the company cares for your home when they"re more focused on making the proper assessment as opposed to simply making a sale. We'll definitely be referring friends and will call back if we ever need any waterproofing/concrete work. Thanks, Jonathan!"

""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.""

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