The financial impact of professional Air Sealing is immediate and lasting. Most of our clients in the Denver metro area see a significant reduction in their annual heating and cooling costs following our service. By effectively blocking heat transfer and sealing off drafts, Air Sealing acts as a permanent shield. Furthermore, we assist you in navigating Xcel Energy rebates and federal tax credits.
A certified technician evaluates your attic's current insulation depth, R-value, air sealing, and ventilation. Thermal imaging may be used to identify hidden cold spots and air leaks.
Before any insulation is added, all gaps, penetrations, and bypasses are sealed with foam or caulk. This critical step prevents conditioned air from escaping and is often skipped by less thorough contractors.
The chosen insulation material is installed to the recommended depth and R-value, with careful attention to ventilation baffles near eaves to maintain proper airflow and prevent moisture buildup.
A post-installation walkthrough confirms proper coverage, depth uniformity, and that all ventilation pathways remain clear. Documentation is provided for energy tax credit applications.

He shared a quote by email before coming out to see my attic. Good communication. Crew was professional and cleaned up well. Thanks!Posted on Ross KelmanTrustindex verifies that the original source of the review is Google. Insulation Nation was fantastic to work with! They showed up on time, were super polite, got the work done in about half the time allotted, and did a great job cleaning up afterwards. Also, despite making an error on his end when calculating the estimate, Josh stuck to the price he promised. Highly recommended!Posted on Wende LathamTrustindex verifies that the original source of the review is Google. I highly recommend Josh's company, Insulation Nation. Josh made the process easy! He is integral, timely, and very conscientious. HIs crew was also outstanding: polite, hard working and non-intrusive. His was the lowest bid but the quality was top-notch. Thank you!Posted on James CTrustindex verifies that the original source of the review is Google. We just completed our second project with Insulation Nation. 2 years ago, they insulated and air sealed our crawl space and last week they air sealed and insulated our attic. Josh was great to work with from the get go on both projects with him being very prompt and communicative. The workers did a fantastic job on both projects too and they were both very reasonably priced. I would highly recommend hiring Josh and his teams! We'll go back to them for any future projects.Posted on Robert MarquezTrustindex verifies that the original source of the review is Google. The team was very friendly, very polite.

Dustin came out and verified the amount of insulation I currently had: R13 and current regulation state. It should be R60. He was able to send a crew out a few days later, and they were so polite, friendly, completed the job quickly and left no mess behind. I am absolutely thrilled that the back 1/3 of my home is actually warm now! Those rooms were about 15° cooler than the rest of my home. Thank you to the entire team!
