Homes built decades ago in Troy, NC were never designed with today's energy standards, and that persistent, bone-chilling draft you feel every winter proves it. Retrofit insulation is the most direct way to upgrade those older structures without tearing down walls or starting over, and Spray Foam Pro delivers exactly that. You get lower energy bills, better indoor air quality, and a home that holds its temperature through every season. It is not just about comfort; it is about making the homes in our community healthier, more efficient, and better prepared for the future.
Adding insulation to an existing home is one of the smartest upgrades a homeowner can make. According to the Department of Energy, homes with spray foam insulation see up to a 40% reduction in energy costs compared to those using standard insulation materials. That is not a marginal improvement; it is a shift that pays for itself over time through lower monthly utility bills and reduced wear on your heating and cooling systems.
The benefits go well beyond energy savings. Spray foam acts as both an insulator and an air barrier in one application, sealing gaps and cracks that traditional materials simply cannot reach. A 2024 study sponsored by NAIMA found that 89% of U.S. single-family homes are under-insulated, so if your home feels drafty or your energy bills keep climbing, you are far from alone.
Not every home was built with proper insulation, and many properties in Troy, NC have wall cavities and attics that are completely empty. Retrofit foam insulation solves that problem by expanding into every crack and gap, creating a complete thermal barrier even in hard-to-reach areas.

Many homes already have some form of insulation, but that does not mean it is doing its job. Fiberglass batts settle over time, blown-in cellulose can absorb moisture and lose its R-value, and neither material provides an effective air seal. Improving existing insulation in buildings often means supplementing or replacing what is already there with a material that actually performs under real conditions.
The process starts with an assessment of what is currently in your walls, attic, and crawl spaces. From there, our technicians determine whether a top-up application or a full replacement makes the most sense for your situation. Either way, the goal is the same: eliminate air infiltration and bring your home's thermal performance up to modern standards.
Things to consider before retrofitting insulation:
Troy, NC has its share of older homes and buildings, many constructed well before modern energy codes existed. These structures often have no wall insulation at all, single-pane windows, and significant air leakage that makes them expensive to heat and cool. Retrofit insulation for old buildings is not a luxury here; it is a practical necessity for homeowners who want manageable utility bills and consistent indoor comfort.
The local climate brings hot, humid summers and chilly winters, which means your home needs to perform well in both extremes. Poor insulation lets conditioned air escape in every season, forcing your HVAC system to work harder than it should. Spray foam addresses this by expanding to fill voids that other materials leave behind, creating an airtight seal that holds up year-round in North Carolina's demanding weather.
Choosing the right material matters, especially in a retrofit situation where installation conditions are more challenging than new construction. The table below breaks down how spray foam compares to other common retrofit insulation materials across the factors that matter most to homeowners.
| Feature | Spray Foam | Fiberglass Batts | Blown-In Cellulose |
|---|---|---|---|
| Air Sealing | Yes, forms an airtight barrier | No | Minimal |
| R-Value per Inch | 3.7 to 6.5 | 2.9 to 3.8 | 3.1 to 3.8 |
| Moisture Resistance | High | Low | Low |
| Lifespan | 80+ years | 15 to 20 years | 20 to 30 years |
| Settling Over Time | None | Can sag | Can settle |

When evaluating the best retrofit insulation materials for your property, consider what matters most for your specific situation. If air sealing and long-term performance are priorities, spray foam outperforms the alternatives in nearly every category.
