If you’re dealing with a hot upstairs, a garage that bakes in August, or an attic that never seems to stop leaking conditioned air, this page tells you exactly what’s going on and what it costs to fix it.
Carrollton’s housing stock is dominated by 1970s through 1990s suburban tract homes, many still running on their original fiberglass batt insulation. Texas heat and humidity have done a number on that material. We know because our crews are in Carrollton attics every week, pulling out settled batts and replacing them with foam that actually seals. Glenn Hartley leads our team, and he’s built Woolsey Insulation Dallas around one habit: a written price before any work starts, every single time.

Why Woolsey Insulation Dallas Is Carrollton’s Preferred Spray Foam Insulation Company
Carrollton homeowners call us for a few reasons that have nothing to do with flashy ads. We show up when we say we will. We leave the attic cleaner than we found it. And we put the guarantee in writing before we start, not after something goes wrong.
Our spray foam crews know Carrollton’s specific housing stock. The homes off Hebron Parkway, around Josey Lane, and through the neighborhoods near Creekview High School all share similar construction eras and failure patterns. When our technicians walk into a 1982 two-story near Hebron High School, they already know what they’re likely to find: settled batts, unsealed top plates, and an attic that hits 140°F or more by early afternoon. That local familiarity means faster diagnosis and pricing that reflects the actual scope of work, not a guess.
Every Woolsey crew member is background-checked and uniformed. You’ll know exactly who’s walking into your home. And every job from a small rim joist sealing to a full attic foam installation is covered by the 365-Day Done Right Promise: if it isn’t right within 365 days, we come back and fix it at no charge. Glenn Hartley stands behind that guarantee on every project in Carrollton.
Crawl Space Spray Foam Insulation in Carrollton
Crawl Space Spray Foam Insulation in Carrollton is a targeted application where we seal and insulate the space between your home’s floor and the ground below, and it usually costs $2,800 to $6,500 for a standard crawl space. Many Carrollton homes built in the 1970s and 1980s have vented crawl spaces that pull humid air into the floor system during summer, making floors feel cold in winter and damp in spring. Closed-cell foam applied to crawl space walls stops that air movement and keeps the space dry.
When Carrollton Homes Need It
If your floors feel cold in January or your utility bills spike every July, the crawl space is often the culprit. In Carrollton’s humid climate, open crawl vents let moisture-laden air condense on ducts and joists. That moisture feeds mold and rots wood over time. Closed-cell foam creates an air and moisture barrier in one pass.
What the Job Involves
We remove any standing water or debris, seal the vents, and spray closed-cell foam directly onto the crawl space walls and rim joists. The foam expands to fill every gap and crack. Most Carrollton crawl spaces take one full day. You’ll get a written price before we start, covering material, labor, and cleanup.
Garage Spray Foam Insulation in Carrollton
Garage Spray Foam Insulation in Carrollton means applying foam to the garage ceiling and shared walls, and it typically costs $1,900 to $4,600 depending on garage size and whether it’s attached or detached. If your garage faces west in a neighborhood like Indian Creek or Woodgate, it’s absorbing direct afternoon sun against an uninsulated door and unsealed ceiling. That heat bleeds into any room above or beside the garage.
Attached Garages and Hot Bonus Rooms
Many Carrollton homes have bonus rooms or bedrooms above the garage. Those rooms usually run 8 to 12 degrees hotter than the rest of the house because the garage ceiling below them is wide open. Open-cell foam on the garage ceiling stops that heat at its source. We’ve seen this single fix resolve complaints that have lasted for years.
Workshop and Storage Use
If you use your garage as a workshop, gym, or storage space, foam on the walls and ceiling makes it usable year-round. Closed-cell foam also helps control humidity, which protects tools and stored items from rust. We quote every garage job with a written, itemized price before any material arrives.
Trusted Brands We Service in Carrollton
We work with eight leading insulation brands, and for Carrollton spray foam work we regularly install Icynene, Demilec, and CertainTeed products. That matters because different Carrollton homes call for different foam chemistry. A vented attic in a 1985 tract home needs different treatment than an unvented roofline in Castle Hills. We recommend the material that fits your home’s construction and your budget, not whatever’s loaded on the truck. Our relationship with these manufacturers means we can source the right product quickly for Carrollton jobs, and our technicians know each brand’s mixing and application requirements cold.
Common Spray Foam Insulation Problems We See in Carrollton Homes
- Settled fiberglass batts in 1970s – 1990s attics. Original batts compress over time and leave gaps at top plates, letting 140°F attic air pour into living spaces. The AC runs constantly, but the upstairs never cools down.
- Missing or misaligned radiant barrier in Castle Hills. Many Castle Hills homes have radiant barrier roof decking with sections missing or installed over gaps. This creates hot spots that aged open-cell foam can’t compensate for, sometimes leading to condensation and mold at the roofline.
- Uninsulated exterior walls in older homes. Some Carrollton homes built before 1990 have empty wall cavities. Humid outdoor air condenses inside those cavities, rotting studs and causing peeling paint. Spray foam would have prevented this, and retrofitting it now stops further damage.
- DIY foam kits that didn’t cure properly. We occasionally find attics where a homeowner attempted a store-bought foam kit. Inconsistent bead thickness and poor mixing leave voids. The fix is more expensive than doing it right the first time.

FAQs About Spray Foam Insulation in Carrollton
Yes, spray foam works with radiant barrier roof decking, and it’s often the best solution for Castle Hills homes where the radiant barrier is improperly installed or missing in sections. The foam creates a continuous air seal and insulation layer that doesn’t depend on the radiant barrier’s condition. Where sections of barrier are missing, closed-cell foam on the roofline fills those gaps and evens out attic temperatures. Call (469) 916-4622 and we’ll inspect your specific attic before recommending anything.
Yes, spray foam fixes hot upstairs rooms in most Carrollton two-story homes, especially those built between 1970 and 1995. The heat comes from under-insulated attics and unsealed top plates. When we remove settled fiberglass and foam the roofline or attic floor, the upstairs temperature difference typically drops within the first week. A homeowner near Hebron High School in a 1980s tract home saw their upstairs stop swinging 10 degrees hotter than downstairs after we foamed the roofline.
Yes, spray foam is safe for retrofitting uninsulated exterior walls in Carrollton homes from the 1970s and later. Closed-cell foam creates an air and moisture barrier that prevents humid outdoor air from condensing inside wall cavities. That condensation is what rots studs and causes peeling paint. Wall retrofitting is more invasive than attic work because it requires access to each stud bay, but for homes with ongoing moisture issues it stops the damage permanently. Call (469) 916-4622 for a wall inspection and written quote.
Spray foam reduces or eliminates ice dams by keeping the attic temperature consistent with the outdoor temperature, so snow and ice melt evenly instead of refreezing at the eaves. Carrollton doesn’t get ice dams often, but the January 2024 freeze caused them in many homes with uneven attic heat loss. Sealing the attic floor and insulating the roofline prevents the warm air that feeds those dams. The Kingswell Guarantee covers this work for 365 days in writing, with a free return visit if the problem comes back.
Yes, spray foam in a Carrollton garage makes a workshop usable year-round, especially if the garage door faces west or south. Foam on the ceiling stops attic heat from cooking the space in summer, and foam on shared walls stops heat loss in winter. For workshop use we often recommend closed-cell on the ceiling and open-cell on walls to balance cost and performance. Expect to pay $1,900 to $4,600 depending on size. Call (469) 916-4622 for an exact written number.
