Fast, Reliable Spray Foam Insulation Across Addison
Spray foam insulation in Addison typically costs $1.80 – $3.40 per board foot for open-cell and $2.60 – $4.90 per board foot for closed-cell, with most whole-attic jobs landing between $2,900 and $7,800 depending on square footage and access. We run crews into Addison five days a week, and a live person answers the phone at (361) 607-0906 when you call. If your condo or 1970s-era home off Belt Line Road is fighting 140°F attic heat every July, spray foam is the retrofit that actually changes the equation. We know Addison’s housing stock because we work in it constantly: tight attics over flat roofs, recessed can lights everywhere, duct runs buried under decades of settled fiberglass. This is our Spray Foam Insulation specialty, and it works.
Why Aspen Attic Insulation Dallas Is Addison’s Preferred Spray Foam Insulation Company
Addison homeowners keep calling us back because we do one thing most insulation companies won’t: we tell you exactly who is coming to your door before they arrive. You get the technician’s name and photo ahead of the visit. If anyone else shows up, the visit is free and we make it right. That’s the Threshold Standard, and it applies to every job we run in Addison. Our techs arrive in clean marked uniforms and show a photo ID badge at the door. No guessing, no strangers walking through your bedroom to reach an attic hatch.
We also put the price in writing before any work starts. Not an estimate scribbled on a clipboard, not a range with fine print. A written number. If you sign off on it, that’s the price. Our 365-Day Done Right Promise covers every job for a full year, labor and materials. If a repair fails, the second visit is free. Garrett Sloane runs our operation, and he keeps it simple: prove who’s coming, prove what it costs, then do the work right.
Spray Foam Insulation Contractors in Addison
Spray Foam Insulation Contractors in Addison deal with a very specific kind of building stock: roughly 60% of Addison’s housing units are multi-family, and most of those buildings went up between the 1960s and 1980s. That means flat or low-slope roofs, limited attic access, and cavities that were under-insulated from day one. A qualified contractor has to understand how to get foam into tight spaces without over-spraying, and how to air-seal before applying anything. Our crew regularly works in complexes along Belt Line Road where the original attic access is a 22-inch scuttle in a closet ceiling. You don’t learn that from a manual.
Open-Cell and Closed-Cell Applications
Open-cell spray foam in Addison runs $1.80 – $3.40 per board foot and makes sense for interior attic assemblies where you want air sealing plus sound dampening. Closed-cell runs $2.60 – $4.90 per board foot and adds structural rigidity plus a vapor barrier, which matters in Addison’s humid summers. We’ve applied Demilec closed-cell to roof decks under rooftop HVAC units in Addison complexes where access meant working on our knees for six hours straight.
Rim Joist and Garage Ceiling Work
Rim joist spray foam in Addison townhomes typically costs $900 – $2,200 depending on linear footage and access. Garage ceiling spray foam, common in Addison homes with bonus rooms above the garage, runs $1,400 – $3,500. We do both regularly, and we air-seal around every recessed can light and duct penetration before spraying.
Spray Foam Attic Insulation in Addison
Spray Foam Attic Insulation in Addison is the retrofit answer for attics that hit 140°F in July and never seem to cool off at night. The older apartments and condos along Belt Line Road were built with fiberglass batts rated at R-19, but decades of compression under HVAC units and foot traffic have squashed them to R-11 or worse. When we spray foam an Addison attic, we’re not adding a layer on top of failing insulation. We’re replacing the system.
Unvented Attic Retrofits
Addison’s flat and low-slope roofs leave very little space for traditional batt replacement. Spray foam applied to the underside of the roof deck creates an unvented, conditioned attic that stops heat from ever entering the living space. We’ve seen the difference in utility bills within a single billing cycle after completing a retrofit on a Belt Line Road condo complex.
Air Sealing Around Can Lights and Duct Runs
Addison’s 1970s and 1980s buildings are full of recessed can lights and duct runs that were never sealed properly. Foam gets into those gaps and closes them. That’s a big reason Addison homeowners choose spray foam over blowing in more loose-fill and hoping for the best.
Trusted Brands We Service in Addison
We stock materials from Demilec, Icynene, and Owens Corning, and we match the product to the specific Addison building we’re standing in, not the product we happen to have on the truck. Demilec closed-cell foam shows up often in our Addison work because it performs well on hot roof decks and limited-access retrofits. For open-cell applications in interior assemblies, Icynene has been reliable across dozens of Addison condos. We keep enough on hand to avoid telling a homeowner we’ll come back next week. When the foam is needed, it’s needed that day.
Common Spray Foam Insulation Problems We See in Addison Homes
- Spray foam applied over old, compressed batts. We see this in Addison apartment retrofits where a previous contractor sprayed directly over failing fiberglass. In Addison’s humid climate, trapped moisture accelerates roof deck rot. The right move is removing the old material first, then air-sealing, then spraying.
- Low-slope roofs with skipped can lights and duct runs. Addison’s flat-roof buildings have tight attics, and some installers skip coverage around recessed lights and duct penetrations because it’s awkward work. Those thermal bypasses spike cooling costs all summer. We don’t skip them.
- Open-cell foam left unsealed around bathroom exhaust vents. During Addison’s spring and fall temperature swings, humid outside air gets pulled into the assembly. The result is condensation and mold in adjacent drywall. We seal every exhaust penetration before spraying.
- Compressed R-19 batts under rooftop HVAC units. Addison’s older complexes often have HVAC equipment sitting directly on attic insulation. Decades of weight crush the batts to R-11 or less. Our crew recently worked in an Addison condo complex off Belt Line Road where the original R-19 batts under a rooftop unit had compressed to under R-11. With attic temperatures already pushing 140°F in July, we air-sealed the penetrations and applied Demilec closed-cell spray foam to the limited-access flat roof deck, cutting the unit’s cooling load noticeably before the next billing cycle.

FAQs About Spray Foam Insulation in Addison
Spray foam, especially closed-cell applied to the roof deck, turns an unvented attic into a conditioned space that stops outdoor heat from ever reaching your ceiling. In Addison’s 140°F summer attics, closed-cell foam typically cuts attic temperatures by 40°F or more within hours of application. Call (361) 607-0906 and we’ll give you a written price for your specific attic.
Yes. We air-seal around every recessed can light and duct penetration before spraying, which closes the thermal bypasses that spike cooling costs in Addison’s older buildings. Skipping them is one of the most common failures we correct. We’ll include that air sealing in your written estimate.
Because Addison’s older apartments and condos have flat or low-slope roofs with limited attic access, and the original fiberglass batts have compressed to R-11 or less under HVAC equipment. Spray foam reaches the roof deck and seals air leaks in one pass, which batts physically cannot do in those tight spaces. Call (361) 607-0906 for a free attic inspection.
When applied correctly with proper air sealing around bathroom vents and penetrations, closed-cell spray foam acts as a vapor barrier and keeps humid outside air out of the assembly. The moisture problems we see in Addison are almost always from open-cell foam left unsealed around exhaust vents. We seal those before spraying, every time.
We primarily use Demilec closed-cell foam for Addison’s high-rise and townhome projects because it performs well on hot roof decks and in limited-access retrofits. For open-cell interior applications, we’ve had consistent results with Icynene. The brand gets matched to your building, not the other way around. Call (361) 607-0906 and we’ll walk you through what makes sense for your property.
