Customers say: Super punctual
67 years of experience

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."

Radon Detection and Reduction questions, answered by experts

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness
