Middle Tennessee homeowners save 30–50% on heating and cooling costs after upgrading to spray foam insulation. Most projects pay for themselves within 3–5 years — and the comfort improvement is immediate.
From attics and crawl spaces to commercial metal buildings, we match the right spray foam system to your project for maximum performance and lasting savings.
With an R-value of approximately 3.7 per inch, open cell foam expands to fill every crack and gap in your building envelope. It creates a powerful air seal while dampening sound between rooms — ideal for interior walls, attics, and bonus rooms where cost-effective coverage matters most.

The premium choice at R-6.5 to R-7 per inch, closed cell foam doubles as a moisture and vapor barrier while adding structural rigidity to walls and framing. It resists flood damage and is the right call for crawl spaces, basements, and any area exposed to moisture.

Your attic is the single largest source of energy loss in most homes. Spray foam applied to the roofline creates a sealed thermal envelope that eliminates hot spots, prevents ice dams, and makes upstairs rooms just as comfortable as the rest of your house — year round.

Unsealed crawl spaces introduce moisture, mold, pests, and musty air into your living space. Spray foam insulation in the crawl space creates a conditioned barrier that controls humidity, deters pests, and dramatically improves the comfort of floors above.

Metal buildings, warehouses, offices, and retail spaces benefit enormously from spray foam's ability to eliminate condensation and maintain stable interior temperatures. We coordinate around your schedule to minimize business disruption and ensure code compliance.

We partner with builders across Middle Tennessee to coordinate spray foam installation around your construction timeline — delivering code-compliant, energy-efficient results from day one.
Learn More →Older homes often have little or no effective insulation — or fiberglass that has sagged and degraded over the years. We assess your existing home's thermal performance and install spray foam where it will have the greatest impact on your comfort and energy bills.
Learn More →Rim joists, garage ceilings, basement headers, and band boards are notorious weak points in a home's thermal envelope. These tight, irregular spaces are exactly where spray foam excels — expanding to fill every void and creating an airtight seal that batt insulation simply cannot achieve.
Learn More →Uninsulated garages and basements bleed conditioned air from adjacent rooms and invite outside temperatures into your home. Spray foam transforms these spaces into usable, comfortable areas while reducing the energy load on your HVAC system.

Don't let poor insulation drain your money, comfort, and property value. Upgrade to spray foam and protect your investment.
Get Your Free Assessment →Walls, attics, and crawl spaces riddled with gaps let conditioned air pour out of your home. It's the equivalent of leaving a window cracked open 365 days a year — and your HVAC system is working overtime to compensate.
Homeowners with inadequate insulation pay significantly more each month in heating and cooling costs. That money is going through your roof — literally. Over a decade, you could waste $10,000 or more on energy you never actually use.
Gaps in your insulation invite warm, humid air into cold cavities where condensation forms. That moisture breeds mold, deteriorates structural framing, and degrades indoor air quality — creating health risks for your family.
If your upstairs is sweltering in summer or your floors are ice-cold in winter, insulation is the root cause. No amount of thermostat adjustment will fix uneven temperatures caused by an inadequate building envelope.
The same cracks and voids that leak air also invite insects, rodents, and allergens into your home. Spray foam fills and seals these entry points permanently — eliminating the pathways pests rely on.
We built this company around a simple idea: treat every home like it's our own. Here's what that means in practice.
Spray foam outperforms fiberglass, cellulose, and blown-in insulation on every metric. Our customers routinely report 30–50% reductions in heating and cooling costs within the first billing cycle after installation.
We carry full liability coverage and workers' compensation so you're never at risk. Every job is performed by trained professionals who follow manufacturer specifications and local building codes.
We inspect your home, identify where you're losing energy, and provide a detailed proposal the same day. No pressure, no obligation — just honest information so you can make the right decision.
Our crew trains directly with equipment and material manufacturers. Proper technique determines performance — there's no shortcut. We invest in ongoing education so every job meets the highest standard.
We lay protective coverings, keep the work area contained, and clean up thoroughly before we leave. You'll know we were there by the comfort improvement — not by the mess.
Most residential projects — attics, crawl spaces, rim joists — are completed in a single day. We respect your schedule and work efficiently without cutting corners on quality.
Real results from real projects in your neighborhood.
"Our electric bill dropped from $310 to $185 the very first month after Telos insulated our attic with open cell foam. We have a 2,400 sq ft home built in the '90s and the difference was immediate. I honestly wish we'd done this years ago — the savings are real and consistent every single month."
"Our upstairs bedrooms were always 8–10 degrees warmer than the main floor. We'd basically given up and just ran window AC units. After Telos sprayed the attic and sealed the rim joists, the temperature is even throughout the entire house. Our kids actually want to sleep in their own rooms now."
"Jonathan and his crew showed up exactly on time, covered everything with plastic sheeting, and were done by 3pm. They walked me through the finished work, answered all my questions, and cleaned up like they were never there. This is how contractors should operate. Highly recommend."
