We’ve sealed and insulated more than 9,000 homes since 2016, and a significant share of them sit right here in Cedar Park - particularly in the master-planned communities built during the 2000s building boom. Our crews dispatch from the Austin office and know the local road network: South US Highway 183, 183A Toll Road, and State Highway 45 North all feed into neighborhoods where we’ve worked. That local routing knowledge means we don’t waste your morning waiting on a crew that’s still figuring out how Avery Ranch Boulevard connects to the rest of the city.

Why Topside Attic Insulation Leander Is Cedar Park’s Preferred Spray Foam Insulation Company

Cedar Park homeowners research before they call. We know this because we read the same reviews you do - the three-star ones especially. Our reputation here is built on documentation, not promises. Every applicable job leaves the homeowner with before-and-after blower-door numbers - a pressurization reading that shows, in one figure, how much conditioned air the home was losing before and after the work.

Response time to Cedar Park averages same-day or next-day, depending on whether we’re running a full attic package or a targeted rim-joist treatment. We serve ZIP codes 78641 and 78645 regularly.

What separates our work in Cedar Park from Austin jobs fifteen miles south is IECC Climate Zone 3. Williamson County sits one zone more demanding than Travis County. That zone difference isn’t bureaucratic trivia - it changes the target R-value, the air-sealing priority, and whether your original 2003 builder-grade insulation is now performing at half its labeled rating. We factor this into every Cedar Park scope.

Our Spray Foam Insulation team has worked extensively in Avery Ranch and The Fairways at Crystal Falls. We know which builders used non-IC recessed can lights, which attic configurations trap moisture at the eaves, and where the original blown fiberglass has settled to effective R-20 or lower after two decades of Texas heat cycling.

Closed-Cell Spray Foam

Closed-cell spray foam runs at R-6.5 to R-7 per inch and acts as its own vapor barrier - critical in Cedar Park’s Zone 3 climate where hard freezes arrive faster and colder than Austin proper. We use closed-cell for rim joists, garage ceiling treatments, and any application where we need structural rigidity or moisture blocking. In Cedar Park homes with pipe chases running through exterior walls, closed-cell at the rim joist is often the difference between a freeze burst and a quiet winter. Materials from Demilec and Johns Manville, selected per job - no proprietary lock-in.

Closed-Cell Spray Foam

Open-Cell Spray Foam

Open-cell runs lighter at R-3.5 to R-3.7 per inch and breathes, making it our choice for most attic floor applications in Cedar Park where we need to manage seasonal moisture movement. In an Avery Ranch home off Avery Ranch Boulevard, we opened the attic and found twenty-two original non-IC recessed can lights punched through the ceiling, with the builder-grade fiberglass blown in 2003 settled to an effective R-20 and actively bleeding conditioned air into the 150°F attic. We air-sealed every can with intumescent gaskets and foam collars, then sprayed closed-cell foam across the recessed-can plane and open-cell over the rest of the attic floor. The homeowner told us the second-story bonus room finally held temperature through an August afternoon.

Open-Cell Spray Foam

Spray Foam Roof Deck

Roof deck spray foam converts vented attics into conditioned space - a high-ROI move in Cedar Park where attic cavities hit 150°F-plus for months straight. By insulating at the roof line instead of the floor, we’re dropping the thermal load on your HVAC ducts and air handler if they’re located in the attic. Most 2000s-era Cedar Park homes have the air handler in the attic; this treatment stops the unit from fighting its own environment. We see this most often in Crystal Falls homes with complex rooflines and limited attic floor access.

Spray Foam Roof Deck

Rim Joist Spray Foam

The rim joist is where your foundation meets your first floor - the single leakiest junction in most homes. In Cedar Park’s older tract construction, these were rarely sealed at build. Closed-cell spray foam here blocks both air infiltration and the condensation that Winter Storm Uri proved can destroy floor framing. We treat this as standard, not optional, on any full-envelope scope.

Rim Joist Spray Foam

Garage Ceiling Spray Foam

Garage ceiling treatments in Cedar Park matter because so many homes here have bonus rooms or bedrooms above the garage. The thermal bridge through an uninsulated garage ceiling makes those rooms the hardest to condition in the house. Spray foam at the garage ceiling - typically closed-cell for its vapor-blocking properties - creates a proper thermal break.

Common Spray Foam Insulation Problems We See in Cedar Park Homes

Common Spray Foam Insulation Problems We See in Cedar Park Homes
  • Non-IC recessed can lights acting as open chimneys. In Avery Ranch and Crystal Falls homes built 2002-2012, the original recessed cans were code-legal but not IC/AT-rated. Each one punches a hole in your thermal envelope. Spray foam installed over them without air-sealing first traps heat at the fixture and violates clearance requirements - a fire hazard and an energy waste.
  • Settled blown fiberglass masking as insulation. Original attic fiberglass in these tract homes has compressed to effective R-20 or lower. Spray foam applied over the top without removing or raking it leaves uneven thickness and voids at the eaves, especially where the original installers blew around ductwork and electrical runs.
  • Pipe-chase condensation from Balcones Escarpment freezes. Cedar Park’s position on the escarpment edge means hard freezes hit harder and faster than Austin. Closed-cell sprayed over an unsealed pipe chase can trap condensation against sheathing, leading to rot. We air-seal the chase first, always.
  • Roof deck foam without proper vapor management. Some contractors spray open-cell directly to roof decking without verifying existing ventilation paths or moisture drive direction. In Cedar Park’s Zone 3 climate with summer humidity spikes, this can accumulate moisture at the sheathing. We specify density and thickness per roof assembly, not per square-foot price.

What Cedar Park Customers Say

Trusted by homeowners across Cedar Park and surrounding areas.

★★★★★

"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."

Clifford E. · Verified customer
★★★★★

"The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."

"Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
