Why Woolsey Insulation Houston Is Spring’s Preferred Spray Foam Insulation Company
We’re not a faceless brand. Woolsey Attic Insulation has been part of the Kingswell family of independently owned and operated insulation companies since 2002, and the Spring crews work under Glenn Hartley’s leadership. What that means for you is simple: the person who answers the phone knows what a Gleannloch Farms attic smells like in August, and the technician who shows up understands why a 2004 brick-veneer house with R-19 batts is baking your upstairs hallway.
Every job we do in Spring is covered by a written price before any work begins and the 365-Day Done Right Promise. If the foam isn’t performing within a year, we come back and make it right at no charge. That’s not a slogan. It’s in writing, on every single job.
Our technicians are background-checked and uniformed. You’ll know exactly who’s walking into your home, and they’ll leave the job site cleaner than they found it. Dispatch and scheduling are coordinated from the brand’s Houston office, but the crews serving Spring are local to the area and know the housing stock well.
Closed Cell Spray Foam Insulation in Spring
Closed cell spray foam insulation is the workhorse for Spring homes with dark shingle roofs and pre-2005 construction, because it creates an airtight moisture barrier that open-cell foam simply can’t match in our humidity. It’s a two-part liquid that expands on contact and hardens into a rigid foam with an R-value of about 6.5 to 7 per inch. For most Spring applications, 2 to 3 inches is enough to hit code and stop radiant heat transfer through the roofline.
Where Closed Cell Foam Earns Its Cost in Spring
On a typical 2003 brick-veneer home west of I-45, we’re spraying closed cell on the underside of the roof deck to turn a vented attic into a conditioned space. That’s the difference between a 138°F attic and one that stays within a few degrees of the living space. For rim joists and band boards, closed cell is the only practical choice here because it blocks both air and moisture, which is exactly what you need when summer dew points in Spring hover in the mid-70s.
Closed cell spray foam in Spring typically runs $1.20 to $2.40 per board foot installed, depending on depth and access. A full attic roofline on a 2,000-square-foot home usually lands between $4,500 and $7,000. The material brand matters too: we work with Demilec and Icynene closed-cell products, selected for this climate because they hold their R-value through expansion and contraction cycles that come with Spring’s temperature swings.
Open Cell Spray Foam in Spring
Open cell spray foam is the lighter, softer cousin: it expands dramatically, fills every odd-shaped cavity, and costs less per inch than closed cell. Here’s the catch for Spring homeowners: open-cell foam is vapor-permeable, which means it lets moisture pass through. In a vented attic with Gulf Coast humidity, that can become a real problem. We’re careful about where we recommend it.
When Open Cell Works Around Spring
For interior walls, soundproofing between floors, or garage ceiling applications where the roof above is well-ventilated, open cell is a smart, budget-friendly option at roughly $0.55 to $1.20 per board foot. In those spots, it does the job without the premium price tag. But we won’t sell you open cell for an unvented attic roofline in Spring, because absorbed humidity from six months of 70%+ relative humidity will degrade its R-value and can promote mold on the roof sheathing.
We sprayed open cell in a Benders Landing home’s garage ceiling last summer, where the room above was a bonus media space. The foam cut the garage-to-bedroom temperature swing by 12 degrees and the homeowner paid $1,900 for the whole job. That’s the kind of specific, honest recommendation you’ll get when you call (903) 447-8369.
Trusted Brands We Service in Spring
Woolsey works with eight leading insulation brands, and for Spring’s climate, we lean on Demilec, Icynene, and CertainTeed most often. Why? Demilec’s closed-cell formulas hold up through the expansion and contraction cycles that come with our July-to-January temperature swings. Icynene’s open-cell products are consistent and predictable. CertainTeed gives us a solid mid-range option when a homeowner wants a name they recognize. The right material fits your home, not whatever happens to be on the truck. Call us and we’ll explain exactly what we’d recommend and why.
Common Spray Foam Insulation Problems We See in Spring Homes
- Open-cell foam in vented attics pulling Gulf humidity: We’ve pulled out open-cell foam in homes near Cypresswood Drive that was installed five years ago and now reads R-19 instead of R-30, with visible mold starting on the sheathing. It’s the most preventable failure we see.
- Closed-cell foam applied too thin under dark shingle roofs: A half-inch of closed cell won’t stop July radiant heat. We’ve measured ceiling temps in pre-2005 west-side homes that stayed above 90°F all afternoon because the original installer sprayed just enough to pass a visual inspection, not enough to actually insulate.
- Foam shrinkage creating gaps at top plates and soffit vents: When contract-grade foam shrinks, it leaves a seam where humid attic air condenses during winter cold snaps. We find these gaps during our inspections with a simple smoke pencil, usually along the top plates where the drywall meets the framing.
- Old R-19 batts left in place under new foam: Some contractors spray over old fiberglass batts to save money. It doesn’t work. The batts compress, trap moisture, and reduce the foam’s effective R-value. For Spring homes built before 2005, this is a common corner-cutting move we’re asked to fix. Our Spray Foam Insulation team always removes or properly addresses the old material first.

FAQs About Spray Foam Insulation in Spring
Homes built before 2005 in Spring typically got R-19 fiberglass batts in the attic, which is about half of what the Department of Energy recommends for our climate zone. Those attics routinely hit 140°F in July, and all that heat radiates straight down through the ceiling. Spray foam seals the attic and stops that heat at the roofline. Call (903) 447-8369 and we’ll inspect your attic and give you a written price.
Not in a vented attic, which is most of what you’ll find in Spring homes built between 1990 and 2010. Open-cell foam absorbs Gulf Coast humidity, loses R-value, and can trap moisture against the roof sheathing. In an unvented attic, open-cell can work if the roofline is fully sealed and conditioned. For most Spring homes, closed-cell is the safer call. We’ll tell you honestly which one fits your house.
Closed-cell spray foam applied to the underside of the roof deck stops heat before it enters the attic. Instead of the attic becoming a 140°F oven that bakes your ceiling, the foam keeps the roofline itself at roughly the same temperature as the living space. In a 2003 Gleannloch Farms home we sprayed last August, the upstairs hallway stayed within 3°F of the thermostat the next afternoon. That’s the difference foam makes.
Shrinkage. Vaulted ceilings are harder to access, so installers sometimes rush the application and the foam pulls back from the framing as it cures. That leaves a gap that lets humid attic air condense on the drywall during winter cold snaps. We check for those gaps on every vaulted ceiling job and fix them before they become a problem. If a previous contractor left them, we’ll find and seal them too.
Yes, in almost every case. Spraying over compressed, dusty R-19 batts is a shortcut that reduces the foam’s effectiveness and can trap moisture. We remove the old material, air-seal all top plates and penetrations, then apply the foam to a clean surface. That’s the difference between a job that works for 20 years and one that fails in three.
