"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

Guardian Basement Waterproofing understands your basement waterproofing needs. We know how to detect the source of water intrusion and stop leaks before they happen. We help our customers reclaim their basements from water, mold and mildew by doing what we do best: finding and repairing the source of their water-related problems. Guardian uses only skilled and experienced technicians to do the job right the first time! As a basement waterproofing company with more than 40 years of waterproofing experience, Guardian stands behind its work with a Lifetime Guarantee. Additional phone number - (410) 484-9812.

"Avoid Guardian Basement – False Promises and Poor Customer Service Two years ago, I hired Guardian Basement to fix a water issue on the front wall of my basement. Joel came out, sold me on their system, and guaranteed I would have a dry basement. We also replaced two sump pumps and had the sump well dug deeper. The main selling point was their lifetime guarantee. Fast forward two years, and I have the exact same problem. Every time there is significant rain, water rushes through the same wall. I reached out to Guardian Basement, and Joel scheduled a time to check it out. His tone was completely different this time—defensive and dismissive. Within five minutes, he claimed, “Your system is clogged.” He made this assessment without any real inspection—just by looking at the cement floor and wall. Now, here’s the catch: If you look closely at their so-called lifetime warranty, clogs are not covered. So despite spending thousands of dollars, I’m back to square one. To make matters worse, Joel was incredibly condescending and unpleasant to deal with. After this experience, I looked into their licensing with the state of Maryland and found multiple complaints against them. I am now in the process of submitting my own complaint as well. I would never recommend Guardian Basement to anyone. Save your money and go with a company that truly knows what they are doing and stands behind their work. If I could give them a negative number of stars I would."

For over 66 years, '58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawl space encapsulation, foundation repair, and mold removal. We lead with a promise of Trusted Five-Star Service, which means the customer experience is at the center of everything we do. Since 1958, we have been steadfast in keeping this promise and upholding the values upon which '58 Foundations & Waterproofing was built: trust, teamwork, integrity, respect, and communication. From the initial call to job completion, our customers are met with knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry. What’s more, you can enjoy the peace of mind that comes with our lifetime warranty and our industry-unique money-back guarantee!

"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone. Their complete disregard for accountability is infuriating. At first, things appeared to go smoothly, but the illusion of competence quickly disintegrated when it came time for the building inspection. The city inspector requires a letter from the project engineer verifying that the work is safe, sound, and compliant with code. 58 Foundations flat-out refuses to provide this basic validation of their work. Why won’t they stand behind their project? Are they hiding shoddy, substandard work? As a homeowner, I’m now saddled with the mess of an open permit and no resolution in sight. This is unacceptable. If a company won’t back their work with a simple letter, what does that say about their integrity—or lack thereof? Didn't expect this kind of run around from a well established professional firm, save yourself the headache."

Basement Waterproofing questions, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.
