"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."

"Roland jr and his crew from MD Waterproofing did a great job under difficult circumstances. A previous renovation by a previous owner dropped the basement floor. What we didnâ t realize is that they had never added underpins so the foundation was undermined. Once Rolandâ s crew broke into a wall to solve a leak, they saw this. They explained the issue clearly and explained the remedy. We were able to quickly get a new quote for the additional work from our company contact, Steve Maney, who was very professional throughout this. Total cost for our house was just over $20k for underpinning two walls and redoing the associated French drains. We will definitely go with MD Water proofing to finish the last two walls, once we have the money saved"

"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."

"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."

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

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
