Solving foundation and basement problems since 1958.

Over 60 Years of Protecting Philadelphia, PA Homes from Sinking Foundations, Moldy Crawlspaces, and Leaky Basements

No matter the season, whether it’s rain or shine, your home is your place of shelter and safety from the elements outside. But what happens when water from the outside enters your home because of cracks in your foundation? From house settlement and hydrostatic pressure against the walls of your foundation, cracks can eventually form in the concrete, creating potential avenues for groundwater to seep through and invade your lower level. Leaks or flooding in your basement or crawlspace can lead to problems ranging from wood rot and property damage to mold growth and humidity problems. Fortunately, when you need a company near Philadelphia, PA that can keep that outside moisture at bay, you can always count on ’58 Foundations & Waterproofing of the Mid-Atlantic!

From being the site of the signing of the Declaration of Independence to being the home of the legendary Philly Cheesesteak, our city of Philadelphia has everything in abundance from history and culture to entertainment and education. But Philadelphia is also home to a lot of rain. With an annual average of 47 inches of rain, Philadelphia receives more than the national average of 38 inches of annual rain. When that water comes down and soaks into your home’s surrounding soil, that building hydrostatic pressure can lead to foundation cracks and eventually groundwater intrusion. It can be difficult to enjoy a visit to the Philadelphia Museum of Art or a great meal at the Double Knot restaurant when you have a bowing basement wall or a flooded crawlspace. But ’58 Foundations & Waterproofing of the Mid-Atlantic has the effective and long-lasting solutions you need to protect your home from excess moisture. With our solutions in foundation repair, crawlspace encapsulation, basement waterproofing, and mold removal, your home will remain a safe, dry, and healthy place for years to come. Enjoy life in Philadelphia while ’58 Foundations & Waterproofing of the Mid-Atlantic keeps the rain outside of your home where it belongs.

As our world continues to change due to the effects of climate change, we can expect our Philadelphia weather to evolve as well. It is predicted that our rainy seasons will be getting a lot wetter, and we might experience the leftovers of tropical storms more frequently. That is why it is vital to be prepared for all that water that will be coming down on our city in the coming years. With our radon-mitigation-ready solutions in waterproofing and our effective solutions in foundation repair, you can make sure that your home is shielded against moisture and groundwater intrusion. Whenever you need a contractor near Philadelphia, PA for basement waterproofing, crawlspace sealing, or stabilizing a sinking foundation, you can always count on ’58 Foundations & Waterproofing of the Mid-Atlantic to get the job done right.
