Hi there from Dustin, owner of Insulation Nation! Here in So Cal, we join our Colorado office in providing personalized high touch experiences for our customers. I work with our customers directly every step of the way from evaluation, education and review of options, through the project and to inspection of the results. We've never seen less than a 5 star review. Small businesses live and die by reviews and we are ready to earn 5 stars on your project! Thank you! C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation questions, answered by experts

Minimal but regular checks can ensure maximum thermal performance.

When installed correctly, radiant barriers can have a life span of anywhere from 80 to 100 years—which, in some cases, is more than certain roofs. While most homeowners who have them installed don’t start to notice any issues for one or several decades, you can ensure no problems pop up by semi-regularly removing dust from reflective sides.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

It may seem that doing an insulating project completely as a DIY task would be the most cost-effective way to accomplish it. However, professionally trained installers are experts at determining precisely what each garage needs in terms of effective insulation. Hiring an insulation pro and using batt insulation for the bulk of the materials will provide the best results for the least amount of money.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
