"We ordered work to waterproof our basement, after a season flooding. I had already shopped for estimates; this one seemed like the best value and quality. Ronald Coleman provided the estimate and I appreciated his straightforwardness and candor in walking me through the work. Rhonda Plaine on the phone was helpful and friendly in helping me to schedule the order and navigate the payment options. It turned out that I also needed to have my external, basement staircase rebuilt, as well, and Ronald and Rhonda helped to add that to the quote and reschedule the work as needed. No flooding since the work was done. I would recommend this company."

"Joel and his crew did a fantastic job. I really appreciated Joel's professionalism and thoughtfulness when he evaluated the problem and formulated the most effective solution. The work was done in a timely and efficient manner. And the best part it is, that I no longer have water in my basement despite many periods of very heavy rain. I also had Guardian waterproof the basement in my former house with similar positive results. I recommend them to the highest extent!"

"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,"

"I've been really pleased with the basement waterproofing job done by Basement Systems USA. Tina, the Production Manager, does a great job of proactively communicating, and the crew does a good job of communicating as well their time of arrival. I usually like to be present when work is going on, but wasn't able to in this case. However, I was happy to see each time I went down, progress, and that it was being done well. Would gladly recommend them to others."

"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."

"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!"

"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

Basement Waterproofing questions, answered by experts

Baltimore homes showing signs like efflorescence on basement walls, persistent dampness after rain, or peeling paint are strong candidates for waterproofing. Properties in low-lying areas or with visible foundation cracks are especially at risk. Homes built before 1950 or with outdated drainage systems often need moisture control upgrades. A professional assessment during Baltimore’s rainy season provides the clearest picture of your basement’s needs.

Helpful?

When hiring basement waterproofing pros in Baltimore, prioritize contractors with proven experience handling the city’s historic row homes and clay-heavy soil. Look for detailed written warranties, clear contracts, and references from local projects. Reliable pros will explain their basement moisture control methods and drainage solutions, not pressure you for upfront payment. Choose someone who understands Baltimore’s frequent flooding and unique foundation challenges.

Helpful?

Basement waterproofing in Baltimore often increases your home’s value and market appeal, especially in neighborhoods with older homes prone to moisture. Buyers appreciate dry, finished basements free from mold and water damage. Waterproofing demonstrates proactive property maintenance and helps prevent costly foundation repairs, making your home stand out in Baltimore’s competitive real estate market and attracting buyers seeking move-in-ready properties.

Helpful?

Baltimore’s humid summers, heavy rainfall, and freeze-thaw cycles make basement waterproofing essential for long-term protection. High groundwater and poorly draining clay soil increase the risk of leaks and foundation cracks. Scheduling projects in late spring or summer allows for optimal drying and exterior work. Understanding Baltimore’s weather patterns helps ensure your waterproofing system is resilient against seasonal moisture and flooding.

Helpful?

Combining basement waterproofing with upgrades like foundation repairs, sump pump installation, or basement finishing in Baltimore can streamline your project and reduce disruptions. Coordinating improvements such as adding drainage systems, vapor barriers, or dehumidifiers ensures comprehensive moisture control. This approach is especially effective in older Baltimore homes, where addressing multiple issues together can help maintain a dry, comfortable, and usable basement space.
