Spray foam insulation cuts heating and cooling costs by up to 50% — and the energy savings typically pay for the project within 3 to 5 years. Joseph Testing Foam has sealed over 1,100 homes and businesses across the Murray area, one properly insulated space at a time.
From single-room retrofits to full commercial buildings, we install the right product the right way — every time.
With an R-value of approximately 3.7 per inch, open cell spray foam expands aggressively to fill wall cavities, irregular spaces, and attic rafters. It creates an excellent air seal that dramatically reduces infiltration and provides notable sound dampening. While it is breathable and not a vapor barrier, it's a highly cost-effective choice for interior walls and attic applications where moisture exposure is limited.

Its rigid, dense structure also adds structural integrity to walls and rooflines — making it ideal for crawl spaces, basement walls, rim joists, exterior applications, and any area with moisture exposure. This is the premium option when performance matters most.

We encapsulate and insulate crawl spaces with closed cell foam to create a clean, conditioned environment beneath your home. The result: warmer floors, better indoor air quality, and a foundation that's no longer a liability.

We create a fully air-sealed thermal envelope at the roofline or attic floor that eliminates hot spots, prevents ice dams in cold snaps, and takes significant strain off your HVAC system. Upstairs rooms that have always been uncomfortable? This fixes them.

That's like leaving a window cracked open every single day of the year. Gaps in your building envelope force your HVAC system to run longer, harder, and more expensively than it should.
Homeowners with inadequate insulation routinely pay hundreds of dollars more per year in energy costs. That money goes into your utility company's pocket instead of staying in yours.
Insulation gaps invite condensation — and condensation invites mold. Left unchecked, moisture damage can compromise structural wood, lower air quality, and generate remediation costs that dwarf the cost of insulation.
When one room is 10°F hotter than another, it's a symptom — not a quirk. Your HVAC is compensating for an insulation failure, and it will keep struggling until the root cause is fixed.
Every gap that lets air in also lets insects, rodents, and airborne allergens in. Spray foam seals those entry points permanently, unlike fiberglass batts that leave pathways wide open.
Poor insulation costs you money every month, reduces your comfort year-round, and quietly lowers your home's value. The good news: it's completely fixable — and faster than you'd expect.

"I was skeptical that insulation could make that big a difference, but our electric bill dropped from $280 a month down to $155 after Joseph Testing Foam did our attic and crawl space. That's real money back in our pocket every single month. I wish we had done this years ago — the payback timeline is better than anything we've put money into recently."
"Our master bedroom and the bonus room above the garage were impossible to live in during summer — easily 10 degrees hotter than the rest of the house. After the attic insulation was done, both rooms felt like the rest of the house within a week. The difference was immediate and dramatic. My kids actually want to spend time up there now, which says everything."
"The crew that came out was professional from start to finish — they arrived exactly when they said, explained everything they were doing, and had the entire job wrapped up in one day. They protected the floors, cleaned up completely, and walked me through the finished work before they left. I've had plenty of contractors who could take notes from these guys."
