Built to Last with CertainTeed Siding

When siding starts to fail, replacing it is often the better long-term solution instead of continuing to patch problem areas. Lehigh Gap Exteriors has been helping homeowners across Eastern Pennsylvania with full siding replacement since 2005, focusing on both appearance and performance.

We install CertainTeed siding on every project because it’s built to handle the conditions homes face in this region. With multi-layer construction and UV protection, it’s designed to resist fading, impact, and seasonal weather changes. CertainTeed offers a wide range of styles, so you’re not limited to one look. Whether you want a more traditional exterior or something with added texture and contrast, there are options that fit your home.

Siding Styles & Options

CertainTeed offers a range of siding styles, allowing you to choose a look that fits your home and your goals.

Horizontal Siding: The most common choice, available in lap and beaded styles for a clean, traditional look.
Vertical Siding: Often used for accents or full sections to create a more modern or distinctive appearance.
Shake Siding: Designed to replicate the look of cedar shake with added texture and no wood maintenance.
Stone Veneer: Adds natural-looking texture for foundations, entryways, or full exterior sections without the weight of real stone.

What to Expect from a Siding Replacement

Siding replacement should feel clear from the beginning, so we walk you through each step before work begins.

Evaluate Your Current Siding

We inspect your existing siding and the structure behind it, looking for moisture damage, worn materials, or other issues that should be addressed before new siding is installed. We help you compare profiles, colors, and finishes so the final look fits your home.

Prepare & Install

Once work begins, our team follows a consistent process focused on proper surface preparation, fastening, sealing, trim work, and clean transitions.

Review the Finished Project

Before the job is complete, we review the installation to make sure everything looks right and is installed correctly. Timelines vary based on home size, prep work, and weather, so we provide clear expectations after evaluating your project.

Common Questions About Siding Replacement

Widespread cracking, warping, or rot across multiple sections usually means the material has reached its useful life. If your siding is aging and heating or cooling costs are rising, replacement is worth considering. Isolated damage on otherwise sound siding is different. Our post on siding repair vs. replacement covers this distinction for older homes.
