Spray Foam Insulation for Lower Energy Bills and a More Comfortable Home

Spray foam insulation solutions trusted by Upstate South Carolina homeowners for over 75 years. We're here to help!

Why Choose Spray Foam Insulation?

If your home feels drafty in the winter, stuffy in the summer, or your energy bills keep climbing, the problem often starts behind your walls and above your ceilings. Traditional insulation materials settle, shift, and lose effectiveness over time, leaving gaps that let conditioned air escape and outside air pour in. Spray foam insulation solves that problem by expanding on contact to seal every crack, gap, and cavity, creating an airtight thermal barrier that keeps your home comfortable year-round.

At Bonham Insulating, we have been helping homeowners across the Upstate South Carolina region experience lower energy bills and more comfortable homes since 1948. We evaluate your property and recommend the spray foam solution that makes the most sense for your home, not the most expensive option.

How Spray Foam Insulation Works

Spray foam insulation is a two-component material applied as a liquid that expands rapidly to fill wall cavities, attic spaces, crawl spaces, and rim joists. Once cured, it forms a rigid or semi-rigid barrier that resists heat transfer far more effectively than fiberglass batts or blown-in cellulose. The result is a tighter building envelope that reduces the workload on your HVAC system and helps maintain consistent indoor temperatures from room to room.

Homeowners who upgrade to spray foam insulation commonly report energy savings of 15% to 50% on their heating and cooling costs. That kind of reduction does not just pay for itself over time — it makes your home noticeably more comfortable from the first day.

Where We Install Spray Foam Insulation

Every home is different, and the best insulation strategy depends on where air leaks and heat loss are occurring. Our team inspects your property to identify problem areas before recommending a plan. Common spray foam insulation applications include:

• Attic insulation — Sealing the attic floor or roofline to prevent conditioned air from escaping through the top of your home, which is the single largest source of energy loss in most houses.
• Crawl space insulation — Creating an airtight seal under your home to block moisture intrusion, improve indoor air quality, and help maintain healthier indoor air throughout the living space above.
• Wall cavities — Filling exterior wall cavities with spray foam to eliminate drafts and reduce outside noise.
• Rim joists and band boards — Sealing the junction between your foundation and framing, a common source of air infiltration that most homeowners overlook.
• New construction — Installing spray foam during the framing stage gives builders and homeowners the most efficient thermal envelope possible from day one.

We are not just installers. We are advisers who take the time to evaluate your needs and recommend the work that makes the most sense—whether that's spray foam, blown-in insulation, or a combination of approaches. That consultative approach is why homeowners trust us and come back when they need additional work done.

Our Spray Foam Insulation Process

We keep things straightforward so you know exactly what to expect. Every spray foam insulation project with Bonham Insulating follows a proven process refined over decades of work in Upstate South Carolina homes.

1. Property Evaluation — We start with an on-site assessment of your home. Our team examines your attic, crawl space, walls, and other areas to identify where air leaks and inadequate insulation are driving up your energy bills. We explain what we find and recommend only the work that makes sense for your property.

2. Preparation and Protection — Before any foam is applied, we protect your property. Floors, fixtures, and surfaces near the work area are covered. Proper ventilation is arranged to ensure a safe and clean installation environment.

3. Professional Application — Our trained, background-checked installers apply the spray foam using calibrated equipment that ensures consistent thickness and coverage. Whether we are sealing an attic roofline or insulating a crawl space, every square inch receives the attention it needs to perform at full R-value.

4. Cleanup and Walkthrough — Once the foam has cured, we clean up the work area and walk you through the finished installation. You will see exactly what was done, where the foam was applied, and how it will improve your home's comfort and energy efficiency going forward.

From the first phone call to the final walkthrough, our goal is to make the process easy and the results lasting.
