'58 Foundations
'58 Foundations
For more than 60 years, ’58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawlspace encapsulation, radon mitigation, mold removal and foundation repair solutions for homes and commercial properties. 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 in upholding the values on which '58 Foundations was built: trust, teamwork, integrity, respect and communication. This comes across in all that we do: from the initial call to job completion, our customers are met with a knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry.
"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone—let alone friends or family. Their complete disregard for accountability is nothing short of infuriating. At first, things appeared to go smoothly. The workers were professional, and the workmanship seemed decent. 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 frustration and inevitable regret. Choose a company that honors their commitments and respects their customers. Once upon a time, 58 Foundations may have been reputable, but their crumbling standards are now painfully obvious. Don’t let their negligence become your problem."

AdvantaClean of Frederick
AdvantaClean of Frederick
Specializing in emergency water damage mitigation, mold remediation, moisture control, Radon mitigation systems and air duct cleaning for residential, commercial and industrial customers.
"AdvantaClean installed a radon mitigation system at my house. Within two years, the piping they put in on the outside of the house to vent the gas collapsed. Upon further inspection, the ~30ft., ~50lb. pipe had been affixed upright by two plastic ties screwed to the siding, and the weight of the pipe had caused the screws to tear through the thin plastic on both ties. Similar systems I've looked at in the neighborhood use lighter, metal, gutter-like pipes, and metal ties (stronger ties for lighter pipes!). When contacted, Dave (the owner) tried to get me to pay $300 to fix it, claiming that he otherwise "couldn't help me" because I couldn't reasonably expect their work to last for almost two years. He also said any kind of warranty was void because "wind damage" wasn't covered. The winds in Frederick topped out at 8mph the day it fell, but I guess he's right. It honestly WOULD be unreasonable to expect this quality of work to hold up to normal weather events (normal storms and winds in a fairly mild weather part of the country) and wear for two whole years! I'm frankly surprised it didn't fall earlier. Oh, and it took me calling AdvantaClean three times to get ahold of him (thought I was promised a call back each time!), but that's way less egregious than the whole "doing sub-par work and trying to get me to pay for it when it failed" thing."
