Wimberley's Hill Country cottages and river cabins sit under cypress shade on pier-and-beam foundations and concrete slabs, with attics that run hot and crawl spaces that run damp. When your cooling bills climb or a bedroom over the garage won't cool down, the culprit is almost always an attic that was never sealed, or insulation that has compressed and failed.

Austin Spray Foam Insulation has been serving Wimberley and the surrounding Hill Country since 2012. We know the building stock here, the summer heat that drives your AC to work eighteen hours a day, and the moisture that collects under metal roofs and in open crawl spaces. We spray foam, we seal air leaks, and we remove and replace insulation that has gone bad. Our crews are fully insured, and we show up on time with a written estimate that names the R-value and thickness we will install.

Spray Foam Insulation in Wimberley (78676)

Wimberley homes built before 1980 sit on pier-and-beam with open crawl spaces underneath. Homes built after 1990 sit on slab. Either way, the attic above them is vented, uninsulated, and running 140 to 160 degrees Fahrenheit through the long string of 100-degree summer days that dominate the Texas Hill Country. Ductwork and water lines run through that attic. In winter, a hard freeze can burst those lines. In summer, the heat radiates down through the ceiling and into the living space below, and your air conditioning runs all day and costs you money every month.

Crawl spaces in Wimberley collect moisture from the clay soil and from summer humidity. A damp crawl space means a damp rim joist, a damp band joist, and eventually wood rot and mold. Closed cell spray foam seals the space, stops the moisture, and protects the structure. Open cell foam works in attics where the priority is sound dampening and where the space stays dry. We choose the foam type based on what the space needs, not on what we want to sell.

Older Wimberley cottages often have empty wall cavities. A retrofit wall injection fills those cavities with foam, seals the air leaks, and raises the R-value without tearing out the walls. Metal buildings and barndominiums sweat without closed cell foam. We have been doing this work in Wimberley and the Austin area for over a decade, and we know the code that applies at your address.

How a Job Works in Wimberley

We start with a free on-site assessment. We look at the attic, the crawl space, the walls, and any insulation that is already there. We ask about your comfort problem: a room that will not cool, a bill that is too high, condensation on the underside of a metal roof, or insulation that smells or has been fouled by rodents. We measure the area, we talk about R-value and thickness, we explain the code that applies in Wimberley, and we give you a written estimate with all the details spelled out.

On the day of the work, our team sets up mechanical ventilation. We remove any old insulation that has failed or that is in the way. We spray the foam in controlled passes, holding the thickness and the ratio that the manufacturer specifies. We stay on site until the foam is cured enough for safe re-entry, which is typically twenty-four to forty-eight hours. If the space is occupied, you will need to leave for that window. We do not rush the cure, and we do not promise immediate re-entry.

We clean up after ourselves. We haul out the old insulation and the packaging. We leave your property the way we found it, minus the air leaks and the bad insulation. We walk you through what we did and answer your questions. We give you a phone number you can actually call if anything comes up.

Attic spray foam in Wimberley typically runs from 1.50 per square foot for open cell to 1.20 per board foot for closed cell, depending on the R-value you need and the thickness we have to spray. A 1,500-square-foot attic with six inches of open cell foam might run 2,200 to 2,800 dollars. A crawl space starts at 2,500 dollars and scales with the square footage and the thickness. Wall injection foam for a retrofit cottage runs from 2 dollars per square foot. Rim joist and band joist sealing starts at 650 dollars. Removal of old, failed, or rodent-fouled insulation starts at 950 dollars, and the cost depends on how much is there and how hard it is to get out. The real price depends on what we find on site: the area to cover, the R-value and thickness you need, whether old insulation has to come out first, and how tight the access is. We do not estimate by phone. Call us at (737) 404-4885 for a free on-site estimate with a written quote you can rely on.

I have a 1970s cottage on a pier-and-beam foundation in Wimberley. The crawl space is damp, and I can see mold on the rim joist. Can spray foam fix that?

Spray foam seals the rim joist and stops the moisture from getting in, but we do not spray over wet wood or active mold. We will look at the crawl space, assess the moisture source, and tell you straight: if there is standing water or active seepage, that has to be addressed first or we walk away. If the wood is dry and the mold is surface-level, we can clean it, let it dry, and then seal it with closed cell foam. Call us at (737) 404-4885 to schedule a free assessment.

My attic in Wimberley gets so hot in summer that the bedroom above the garage is unbearable. Will spray foam cool it down?

Spray foam will raise the R-value of your ceiling and reduce the heat load coming down from the attic into that room. Whether it solves the comfort problem depends on the room itself: if the room is small and the AC duct is undersized, foam alone may not be enough. But if the attic is uninsulated or poorly insulated, foam will make a real difference. Open cell foam is usually the right choice for an attic, and it typically runs 0.55 per board foot. We will give you a realistic estimate of what you can expect to gain, and we will be honest if the room needs something else, like a duct extension or a supplemental AC unit.

I am thinking about spray foam for my Wimberley home, but I want to know what it will cost before I call.

We cannot give you a firm price without seeing the space, but here is a realistic range. Attic foam starts at 1.50 per square foot for open cell. A 1,200-square-foot attic with four inches of foam might run 1,800 to 2,200 dollars. Wall injection in a retrofit cottage runs from 2 dollars per square foot. A crawl space starts at 2,500 dollars. Removal of old insulation starts at 950 dollars. The final price depends on R-value, thickness, what has to come out first, and how tight the access is. Call us at (737) 404-4885 for a free on-site estimate.

What does the building code in Wimberley say about attic insulation and spray foam?

Wimberley follows the energy and building code that applies at your address, and the local building official enforces it. The code sets the R-value you need based on the climate zone, the ignition barrier that has to separate the foam from the attic space, and the thermal barrier that has to separate the foam from the interior of the home. The thermal barrier rule is the one most installers get wrong, and it is the one that matters most. You can find out what applies at your property by contacting the City of Wimberley through its official city website at https://www.cityofwimberley.com, or by calling the building department. We know the code, we follow it, and we will help you understand what it requires at your address.

Can we stay in the house while you spray foam the attic in Wimberley?

You can stay in the house, but you will need to leave the attic space and the rooms below it for twenty-four to forty-eight hours during the cure window. We set up mechanical ventilation to move the fumes out, and we keep the work area sealed off. The smell during cure is normal and it goes away as the foam hardens. If you have pets or children with respiratory sensitivity, plan to stay elsewhere for the cure period. We will give you a clear re-entry window when we schedule the work.

Are you insured to do spray foam work at my Wimberley home?

Yes, we are fully insured with general liability and workers' compensation coverage. If something goes wrong on the job, you are protected. We also carry the insurance that Wimberley and the surrounding cities require. Before any contractor starts work at your home, ask them for proof of insurance and verify it with their carrier. We are happy to provide that documentation.

I have a metal building in Wimberley that sweats in the summer. Is that a moisture problem or an insulation problem?

Metal buildings sweat because the interior air is warm and humid, and the metal roof is hot. When warm air hits the cold metal, condensation forms on the underside. Closed cell spray foam on the underside of the roof and walls stops the condensation by creating an air-tight seal and raising the temperature of the interior surface. It also raises the R-value so the building stays cooler. If the building is already dripping water, we spray foam. If there is standing water inside or the roof is leaking, that has to be fixed first. Call us at (737) 404-4885 to assess the building and give you a plan.
