Danville sits on the edge of Hendricks County farm country, where frame homes and brick ranches built in the 1950s and 60s cluster around the town square alongside working pole barns and newer barndominiums spreading across the flat Indiana till plain. Those homes were built to a different standard than today, and their attics, crawl spaces and wall cavities have been fighting the central Indiana climate ever since.
Homeowners in Danville (46122) call Indianapolis Spray Foam Insulation because we understand what happens when a 70-year-old attic bakes at 140 degrees in July and drops below zero in January, when a crawl space sweats in spring and frosts in winter, and when the empty wall cavities behind original siding let the weather straight through. We have been serving Danville and the Indianapolis area since 2012, and we know what works here.

Danville's housing stock splits between mid-century brick and frame ranches on shallow crawl spaces and slabs, and newer two-story homes over basements and crawl spaces with bonus rooms above three-car garages. The attics in both are the real problem. Original insulation has settled flat, moisture collects in the corners and rafters, and the rim joists where the walls meet the foundation are often completely uninsulated. In summer, air conditioning runs all day trying to cool a space that is 130 to 150 degrees at the roof deck. In winter, ice dams form because the attic stays warm enough to melt snow, and condensation appears on the sheathing when the humid inside air meets the cold surface. Crawl spaces under those ranches sweat in spring and early summer, and if the original insulation is damp or has settled, mold and odor follow.
Closed cell spray foam seals the attic and stops the air leakage. Open cell foam works in walls and sealed cavities where moisture is managed by the vapor drive of the season. Wall injection foam reaches the empty cavities inside your exterior walls without tearing them open. Our team has been sizing and spraying these assemblies in Danville for over a decade. We specify R-value and thickness on every estimate so you know what you are paying for, and we measure the work on site to make sure it is right.

How a Job Works in Danville
We start with a free on-site assessment. We walk your attic, crawl space or walls, take measurements, and ask about your comfort complaints and your utility bills. We look for damp insulation, condensation, air leaks around ductwork or penetrations, and any moisture or odor that has to be addressed before foam goes in. We leave with photos and dimensions, and we come back with a written estimate that names the R-value, thickness, and square footage or board footage of foam we are going to install.
On the day of the work, our fully insured crew arrives with equipment and material. We set up mechanical ventilation to run during the spray and cure. If old insulation has to come out first, we remove it and haul it away. We spray the foam in controlled passes, holding the specified thickness on each pass so the R-value is real. For attics, we tape off soffit vents or baffles so air can still reach the underside of the roof deck if the code at your address requires ventilation. We respect what the building official has set, and we follow it. Once the foam has cured, we do a final walkthrough with you, answer your questions, and leave the property clean.
Attic spray foam in Danville 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 hit. A 1,500 square foot attic with existing settled insulation that does not have to come out might run $2,000 to $3,500 for a top-up to R-40 or R-50. If the old insulation is damp or contaminated and has to be removed first, add $950 to $1,200 for removal. Wall injection foam for a frame house with empty cavities runs from $2 per square foot depending on the wall area and access. Crawl space foam starts at $2,500 and goes up with the square footage and the moisture condition of the substrate. Rim and band joist sealing starts at $650. The real cost drivers are the area to cover, the R-value and thickness you need, whether the space has to be cleared first, and how tight the access is. We give you a firm written estimate after we see the job. Call us at (463) 285-8584 for a free assessment, or tell us about your space and we will give you a ballpark figure over the phone.
