Retaining Wall Construction in Allentown
As a homeowner in Allentown, PA, you're no stranger to the challenges of soil erosion and unstable landscapes. With its cold climate and heavy rainfall, the city's terrain can be unforgiving, especially after a long winter when snowmelt floods can leave your yard looking like a river delta. Building a retaining wall is not just a matter of aesthetics; it's a necessity for ensuring your property remains stable and secure.
In Allentown, the median year built of homes is 1951, which means many of our residents are dealing with aging infrastructure that may require additional support to prevent soil erosion. With heavy snowfall averaging 45" annually, it's essential to have a retaining wall constructed from materials like interlocking block or poured concrete that can withstand these forces. A well-built wall can help prevent foundation heave and roof damage assessment, ensuring your home remains safe and secure.
A cost range of $3,000-$10,000 may seem daunting, but the benefits far outweigh the expenses. Not only will a retaining wall add visual interest to your landscape, but it'll also provide peace of mind knowing your property is protected from erosion and flooding. With the median household income being $53,403 and homeownership rate at 42.3%, investing in a reliable retaining wall can be a wise decision for any Allentown homeowner.

DIY vs. Call a Pro
Retaining walls under 3 feet tall are manageable DIY projects using interlocking landscape blocks. Excavate a level trench, add compacted gravel base, stack blocks with construction adhesive, and backfill with drainage gravel behind the wall.
Call a professional when:
Hire a professional for walls over 3-4 feet tall (may require engineering and permits), walls supporting structures, walls on steep slopes, or natural stone walls requiring skilled masonry.
