Insulation work in Indianapolis by Holliday Insulation

Insulation Contractor in Indianapolis, Indiana

Spray foam, batt, and blown-in insulation for Indy homes and commercial buildings — strongest on the east side, minutes up I-70 from our shop.

Big-city energy bills, fixable causes

Indianapolis has some of the most varied housing in the state — and from Irvington bungalows to Warren Township ranches, the energy-bill culprits repeat: thin attic insulation, uninsulated walls, and leaky rim joists. A blown-in attic upgrade to R-38 is usually the fastest payback in the city; spray foam air-sealing handles the drafts no batt ever will; and closed-cell crawl space encapsulation ends the cold-floor, musty-basement cycle.

On the commercial side we bring what most residential crews can’t: NFPA 285 tested assemblies, DC 315 intumescent coatings, refrigeration insulation, and masonry water repellents — fire-code work is in this company’s DNA; the founder spent years in the fire service.
