Post sits in the heart of Garza County ranch country southeast of Lubbock, where older brick and frame homes share the landscape with metal outbuildings, equipment sheds, and newer barndominiums scattered across the flat South Plains. Most homes in town are built slab-on-grade with vented attics that pull in dust and summer heat, and the construction gaps around windows, doors, and rim joists let wind-driven air find its way inside after a dust storm rolls through.
When your cooling bills spike in July or dust keeps seeping in no matter how many times you caulk, that is when homeowners in Post call Lubbock Spray Foam Insulation. We have been serving Post and the surrounding Lubbock area since 2009, and we know exactly why attics overheat here and where the air leaks come from. Our fully insured crews handle everything from attic foam and air sealing to metal building insulation and insulation removal, all with written estimates that spell out the R-value and thickness you are paying for.
Spray Foam Insulation in Post (79356)
Post's housing stock reflects decades of steady growth on the South Plains. Older homes in town were built with minimal attic insulation that has settled thin over the years, while the flat terrain and slab-on-grade construction mean HVAC ductwork runs through vented attics that turn into ovens once summer temperatures climb toward or above 100 degrees. The real enemy here is not moisture pushing through walls but attic heat gain baking your ductwork, plus dust and wind-driven air finding every gap in a wall cavity or top plate. Winter cold snaps bring their own draft problems, and the dry climate means a sealed building envelope pays off fast.
Metal shops, equipment buildings, and barndominiums need their own approach. A metal roof or metal skin with no insulation turns unbearable in July, and a sealed roof deck with closed cell foam stops both the heat and the dust. We have been spraying attics, crawl spaces, walls, rim joists, and metal buildings in Post and the Lubbock area for over fifteen years. Our team knows the local building codes, the soil conditions that affect crawl space work, and the access challenges in older frame houses and modern metal structures alike.

How a Job Works in Post
We start with a free on-site assessment at your Post property. We look at the attic or wall cavity, check what insulation is already there, measure the area to be sprayed, and talk through whether open cell or closed cell foam makes sense for your use and budget. We provide a written estimate that includes the R-value, thickness in inches, and the total cost. No surprises.
On the day of the work, our fully insured crew arrives with the spray rig and sets up mechanical ventilation. If old insulation has to come out first, we handle the removal and haul it away. We spray the foam in controlled passes to hit the specified thickness and R-value, and we maintain proper drum temperature and manufacturer ratio throughout. Once the foam is cured, we trim excess material and clean up the work area so your property is left neat.
For attic work in an occupied home, we set a re-entry window of twenty-four to forty-eight hours after the last pass. That gives the foam time to cure fully and the smell to dissipate. We walk you through what to expect and answer any questions before we leave.
Attic spray foam in Post typically runs from $1.50 per square foot for open cell foam on top of existing insulation, up to $2.00 or more per square foot if old insulation has to be removed first. A 1,500 square foot attic with removal and closed cell foam might land in the $3,500 to $5,000 range, depending on access and thickness. Wall injection foam for closed cavities starts around $2.00 per square foot. Crawl space foam starts at $2,500 and goes up with the size of the space and whether moisture remediation is needed first. Rim joist and band joist sealing starts at $650 for a targeted area. Insulation removal runs from $950 depending on volume and haul-away. The biggest cost factors are the area to cover, the R-value and thickness you want, whether you choose open or closed cell, what old material has to come out, and how tight the access is. Every job is different, so we always measure on site and give you a firm price in writing. Call us at (806) 853-5452 for a free estimate on your Post home or building.
