Serving Rapid City, SD and surrounding areas. (605) 646-9056
Rapid City Insulation Company was founded in 2025 by a crew that had spent years working on homes across the Black Hills region and kept seeing the same problem: homeowners paying high heating bills because their crawl spaces, attics, and rim joists had never been properly insulated. Rapid City homes - especially the ranch houses and bungalows built through the 1950s, 60s, and 70s in neighborhoods like Canyon Lake and West Boulevard - were built long before anyone cared much about energy efficiency.
We set out to fix that, one home at a time. We are a local company, which means when you call us, you are talking to someone who lives here, who knows what a Rapid City winter feels like, and who understands why a Chinook wind can make your house feel drafty in January when it was fine the day before. We are not a national franchise with a call center three states away.
Our focus is tight: insulation and air sealing done right. We offer 16 insulation and moisture-control services and serve 12 communities across South Dakota, Wyoming, and Nebraska. Every job gets a written estimate, a clear process, and a follow-up to make sure you are satisfied.
We give you a clear, written estimate with no pressure to decide on the spot. What we quote is what you pay.
Rapid City homeowners have told us the hardest part of hiring a contractor is getting them to actually appear. We schedule and we keep it.
If something is not right after we finish, call us. We stand behind every installation with a satisfaction guarantee.
We clean up after ourselves, protect your floors and belongings, and leave your home exactly as we found it - minus the drafts.
