Halliday Sealcoating & Striping | Masonry/Concrete & Roofing in Jonestown, PA 17038

In our Pennsylvania climate, winter freeze-thaw cycles and de-icing salts can rapidly degrade unprotected asphalt, leading to cracks and potholes. Our sealcoating service acts as a protective barrier, sealing out water, oil, and UV rays that cause asphalt to become brittle and crack. For areas like driveways and walkways, this preventative maintenance is key to avoiding costly repairs from ice dam runoff and salt corrosion, extending the surface life significantly.

Absolutely. We apply professional-grade sealants designed for masonry and concrete surfaces like patios, porches, terraces, and retaining walls. This process protects against moisture penetration, which is crucial in our humid seasons, preventing efflorescence (white salt deposits), mold growth, and freeze-thaw spalling. Sealing these surfaces preserves their appearance and structural integrity, whether they are new installations or existing features needing resealing.

While we specialize in horizontal surface protection, rusting roof flashing is a critical issue for Jonestown homes as it can lead to water intrusion and interior damage, especially after heavy snow or ice dams. We recommend a targeted sealing approach for the masonry or concrete areas where the flashing meets, such as chimney bases or wall intersections. By properly sealing these junctions, we can help prevent water from seeping behind compromised flashing, providing a crucial layer of defense while you address the roofing repair with a specialist.
