Baltimore County Siding Replacement Upgrades 50-Year-Old Exterior

This Baltimore County Siding Replacement Upgrades 50-Year-Old Exterior project completely transformed the appearance and weather protection of this longtime family home with new CertainTeed MainStreet vinyl siding in Sterling Gray. After recently trusting the Roof Right team with a roof replacement, the homeowner reached back out when aging siding and missing panels on the front porch made it clear the exterior was ready for a full upgrade.

Project Overview: Baltimore County Siding Replacement

The home’s original siding had been in place for more than 50 years and was beginning to show its age in several areas around the property. The homeowner first noticed the problem after pieces of vinyl siding began coming loose and disappearing from the front porch area, leaving sections of the home exposed and negatively impacting curb appeal.

On older homes throughout Baltimore County, siding systems that have been exposed to decades of sun, wind, moisture, and seasonal temperature swings often begin failing around transition areas first. Once panels loosen or detach, surrounding sections can become more vulnerable to additional wind damage and moisture intrusion.

Because the homeowner had already worked with our team during a recent roof replacement project, she knew she wanted a long-term solution instead of continuing to patch isolated siding issues on an aging exterior system.

Removing the Old Siding & Preparing the Home

Before installing the new siding system, our crew completely removed the existing siding from the home and carefully inspected the wall system beneath. On older homes, this step is important because it allows hidden problem areas to be identified before new materials are installed over top.

Once the wall surfaces were prepared, our team installed brand-new Tyvek housewrap across the home to help improve moisture protection behind the siding system. Housewrap acts as an important secondary weather barrier, helping prevent wind-driven moisture from reaching vulnerable wall components while still allowing the home to breathe properly.

Special attention was also given to sealing around windows, trim areas, and exterior cutouts to help strengthen the home’s overall weather resistance.

Adding Insulation & Energy Efficiency Improvements

After the housewrap installation was complete, our crew installed GreenGuard fanfold insulation across the exterior walls before the siding installation began. Adding insulated fanfold beneath vinyl siding can help improve overall energy efficiency while also creating a smoother and more consistent finished appearance.

On older homes with aging exterior systems, adding this additional insulation layer can help reduce drafts and improve thermal performance throughout the year.

CertainTeed MainStreet Siding in Sterling Gray

To complete the transformation, the homeowner selected CertainTeed MainStreet vinyl siding in the Sterling Gray color. The updated siding dramatically changed the appearance of the home, replacing the worn and weathered exterior with a cleaner, more modern finish.

CertainTeed MainStreet siding is designed to provide low-maintenance durability while maintaining long-term curb appeal through changing weather conditions. The Sterling Gray color gave the home a fresh updated look while still fitting naturally within the surrounding Baltimore County neighborhood.

Compared to the aging siding that had protected the home for more than five decades, the final result was a major improvement in both appearance and exterior protection.

Signs You May Need a Baltimore County Siding Replacement

Older siding systems often show warning signs before larger exterior problems develop. Homeowners should watch for issues such as:

• Missing or loose siding panels
• Cracked or warped vinyl siding
• Faded or brittle exterior surfaces
• Increased drafts inside the home
• Higher energy bills
• Water staining near walls or windows
• Frequent siding repairs
• Siding systems more than 30–40 years old

Replacing aging siding before widespread failure occurs can help protect the home from moisture intrusion and improve long-term energy efficiency.
