The crew was friendly and efficient during their 2 days on our property. They cleaned up after each day's work and when they needed to be inside our home accessing the ceiling doors to our attic, they left no evidence of occupancy. Highly recommend this company for your insulation needs."

We can be reached at 720-517-0011. We have been in the Insulation Industry for almost 3 decades now. We have done most types of construction projects from multi-million dollar commercial projects, small to large remodels projects and large track home developments. About 7 years ago, we started working with a few select custom green energy builders. This afforded us the opportunity to work directly with homeowners to develop insulation and energy plans that fit their needs. We quickly realized how much we enjoyed working directly with homeowners vs. a big builder that may not have the buyer's long term interests at heart.

"I had 1700 sf of attic space insulated and air sealed in a two attic, tri-level house. Ryan was absolutely awesome. He was very knowledgeable and answered everyone of my questions...I had a lot. They showed up early to every appointment. Once the job was completed, they did an awesome job cleaning up and vacuuming with their HEPA vacuum. I would highly, highly recommend these guys. They also filled out the Xcel rebates for me and subtracted from my bill. AND, they did a blower door test to validate the air leakiness of my house. They were able to reduce my leakiness by 52%!!! The next day, I could feel the difference already!"

"Dustin and Josh were great to deal with up front and stated they would do what I requested. After finishing the crawl space cleanout, it was noticed that the skirt doors were open and the cats were again in the space. I then hired someone to close up the openings. I crawled into the space which had a new vapor barrier and noticed that much insulation repair was not done as paid $500 extra for. Under the vapor barrier was very rough and bumpy and very hard to crawl on. they did not clean the rocks and cat messes up and the insulation was not repaired as promised and paid for.s I would not use them."

Insulation services FAQs

When choosing a professional insulation installer, consider asking these questions to determine the best fit.

  • Will you address air leaks in my house?

  • Can you provide an R-value (heat resistance) fact sheet?

  • What kind of insulation will work best for my home?

  • How do you handle signs of a water leak?

  • Are you licensed and insured?

  • Can you provide customer references?

The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:

  • High heating and cooling bills

  • Uncomfortable room temperatures 

  • Ice dams on the edge of your roof 

  • Roof leaks

  • Cold floors and walls

  • Freezing pipes

  • Temperature fluctuations

  • Visibly low insulation

  • Noise problems

  • Pest problems

On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:

  • Blown-in: $1–$4 per square foot

  • Spray foam: $2–$5 per square foot

  • Batt: $2–$4 per square foot

  • Structural insulated panels: $4–$7 per square foot

  • Loose-fill: $2–$5 per square foot

  • Reflective: $0.50–$1.50 per square foot
