Why Woolsey Insulation Austin Is Lakeway’s Preferred Spray Foam Insulation Company
Lakeway homeowners call us because we pick up the phone and we show up. Not a call center. A live person answers 24 hours a day, 7 days a week. When a garage ceiling starts sweating onto a car in Rough Hollow or an attic hot spot shows up above a bedroom in the Hills, the homeowner wants someone on the way, not a voicemail. That is exactly how we run.
We carry real material options on our trucks: Demilec closed-cell, Icynene open-cell, and others. The recommendation depends on the house, not whatever happens to be loaded that morning. Glenn Hartley runs our crew with a simple rule: quote the job honestly, show up in the window we promised, leave the site cleaner than we found it, and put the guarantee in writing. That is The Kingswell Way, and it is why Lakeway homeowners keep our number.
Garage Spray Foam Insulation in Lakeway
Garage Spray Foam Insulation in Lakeway is one of the most common calls we take, and it usually starts the same way: a homeowner notices condensation on the garage ceiling, rust forming on door tracks, or a bonus room above the garage that cooks in the afternoon. Lakeway’s proximity to Lake Travis means humid air hangs around garages, especially in the mornings. When that moisture meets an uninsulated ceiling, it condenses. Closed-cell foam seals the ceiling and stops the air movement that carries the humidity.
Most garage ceiling spray foam jobs in Lakeway run $1,800 to $4,200. That includes prep, masking, spraying, and cleanup. We give you the exact written number before any work starts. The 365-Day Done Right Promise covers the work in writing after it is finished.
Bonus Room Floors Above Garages
When a bonus room sits over a garage, the floor cavity is usually the uninsulated boundary, not the garage ceiling itself. We foam the underside of the floor deck from inside the garage. This cuts heat gain from below and stops the garage’s humid air from creeping up into the living space. In Lakeway homes with western exposure, this one fix often solves the “hot bedroom above the garage” complaint.
Classic Car and Workshop Garages
Lakeway has no shortage of enthusiasts with serious cars and workshop setups. Unconditioned garages swing hard with outdoor temperature, and humidity from Lake Travis accelerates rust. Closed-cell foam on the ceiling and the garage door header reduces that swing significantly. We have done same-day calls in Rough Hollow where the fix was done before the weekend heat arrived.
Closed Cell Spray Foam Insulation in Lakeway
Closed Cell Spray Foam Insulation in Lakeway is the denser, water-resistant option we recommend for garages, rim joists, roof decks, and anywhere moisture is a real concern. It cures into a rigid foam roughly twice the R-value per inch of open-cell. That matters in Lakeway because homes near Lake Travis deal with humidity that open-cell alone sometimes cannot hold back. Closed-cell also adds structural strength to wall assemblies, which is useful in older lake cottages with irregular framing.
Closed-cell foam in Lakeway runs $4.10 to $6.90 per board foot installed. Rim joist jobs typically run $1,500 to $3,200. Roof deck applications start around $5,000 and go up from there depending on roof geometry. Every quote is delivered in writing before the crew unloads a single tool.
Rim Joist Sealing
The rim joist is the wooden band that sits on top of your foundation wall around the whole house. In Lakeway homes from the 1980s and 1990s, these are often unsealed or poorly insulated. Air and humidity pour in through the gaps. We spray closed-cell directly onto the rim joist from inside the crawl space or basement, sealing it air-tight in one pass.
Roof Deck Applications
Some Lakeway homeowners choose to move the thermal boundary to the roofline by foaming the underside of the roof deck. That creates a sealed, conditioned attic. It works well in Lakeway’s Hill Country homes with ductwork running through attics, because those ducts stop baking in the summer heat. It also cuts dust and pollen intrusion during cedar season.
Trusted Brands We Service in Lakeway
We install and service spray foam from names Lakeway homeowners know: Demilec, Icynene, and Owens Corning. GreenFiber blown-in options are available for homes where a hybrid approach makes more sense. Carrying multiple brands means the recommendation fits the house. Some Lakeway homes benefit from closed-cell on a garage ceiling and open-cell in an attic. Others need the moisture control of a specific Demilec product near the lake. We show up with the right material, not just what is easiest to spray. Most repair calls in Lakeway are diagnosed and quoted within an hour of arrival.
Common Spray Foam Insulation Problems We See in Lakeway Homes
- Western-facing attic hot spots from thin open-cell foam. Older Lakeway attics sprayed years ago often have open-cell applied too thin. By July, the afternoon sun cooks the roof, and that heat bleeds into bedrooms below. Homeowners notice the AC running nonstop in the evening. We inspect the existing foam depth and target only the bays that failed.
- DIY foam shrinking around garage door headers. We see handyman-applied foam around Lakeway garage door headers that has pulled away from the metal. That gap lets humid lake air in year-round, and the door tracks start rusting within a season or two. The fix usually means cutting out the old foam and re-spraying with closed-cell.
- Closed-cell sprayed over moisture-damaged fiberglass. Some Lakeway homes had closed-cell applied directly over old batt insulation without removing the wet or damaged fiberglass first. That traps moisture inside the wall cavity, especially in homes near Lake Travis. Our crews will not do that. We inspect first and remove damaged material before spraying.
- Unsealed attic hatches in older lake cottages. Many Lakeway homes built as lake cottages decades ago have attic hatches that were never air-sealed. The hatch becomes a chimney for conditioned air in summer. We can repair just the foam and weatherstripping around the hatch without redoing the whole attic.

FAQs About Spray Foam Insulation in Lakeway
Usually the same day, and at most next morning. The Hills of Lakeway is a regular route for us, and we keep repair windows open during the week for exactly this. Call (361) 418-9997 with what you are seeing, and we will give you a straight answer on when a tech can be there.
Closed-cell is the right call for most Lakeway garage conversions, particularly if the garage faces Lake Travis or stays humid. The denser foam stops moisture movement and adds strength to the framing. Open-cell works for interior walls. We will tell you which fits your specific conversion and give you the written price before starting.
Yes. We do targeted repairs around attic hatches, scuttle doors, and can lights in Lakeway homes all the time. The fix usually takes an hour or two. You do not need to re-spray the entire attic to solve a hatch leak.
Open-cell sprayed too thin in attics that face full western exposure. The foam never reached the depth it should have, and the western sun overpowers it by mid-afternoon. We see it most in homes built during the 1990s boom around Lakeway. The fix is usually adding closed-cell to the worst bays rather than redoing the whole attic.
Yes, and it is the smart order to do it in. Fix the foam first, then size the new AC for a properly insulated attic. If you replace the AC first and fix the foam later, the new unit may be oversized for the load it actually faces. We work with HVAC contractors in Lakeway regularly, so we can time the work without conflict. Call (361) 418-9997 and we will walk you through the sequence.
