Spray Foam Insulation in Fort Collins, CO

Quick, professional installation with excellent communication throughout the process. The team was on time, efficient, and easy to work with. Highly recommend L&L Insulation!

It was great working with a company that treats the little guy the same as a big builder. Kevin Miller made me feel just as important as a national builder even though I am a local contractor. Would definitely recommend L&L for all your insulation needs and do so whenever I am asked about insulation needs.

Kevin is awesome and clearly loves his company and the industry he is in. We needed our crawl space and garage to be insulated. He went far above and beyond what we could have ever hoped for. It turned out amazing! The work was clean, professional and affordable. Not sure what else you could ask for!

This company did a crawl space encapsulation and radon mitigation system for me. They were wonderful. Great guys, on time, left the place cleaner than it was. Highly recommend!

Connected with Ascend through the Fort Collins energy rebate program. Talked with Lizzy on the phone and Chris came out for the estimate. Super easy to work with and great communication all around. We decided to have our attic sealed (spray foamed) and new blown-in insulation installed. When it came time to do the work, Pete and crew were all very polite, professional and kept our home clean during the process. Again, communication was outstanding. Never was I wondering where we were at in the process or what was happening next. Work was completed on time with no outstanding issues. Highly recommend and will use them again for future projects.

Everyone at Ascend was incredibly warm, helpful, and professional. They did an excellent job with my installation, and were communicative at every step. Further, they helped explain how to apply for a rebate from my energy company and walked me through the tax implications in a clear way that made everything go smoothly. I cannot recommend them enough!

I had a great experience. Very professional and courteous. Got a hold of me in timely manner. Highly recommend.

They are a reputable company that does what they say they will do. I appreciated the line of communication they kept. Highly recommended.

Communication was great, answered all my questions and they were on time. I recommend this Company. 👍

Timberline Insulation was great to work with. John answered all of our questions, provided us with a fair quote, and got us scheduled within a very reasonable timeframe. We are extremely happy with the results and can tell a significant difference from the work performed. The installation crew was very professional and efficient. We highly recommend this company.

EXTREMELY PROFESSIONAL!!! John and his crew were/are very knowledgeable and simply did great work. They were very good at explaining the details of insulating a new house, as well as even educating me on other code issues. If you want a good job done, go with Timberline. None finer!!

We obtained in-home quotes from several insulation companies to upgrade our home insulation, air seal, and install a whole house fan. After narrowing it down to 2 possible contractors, we chose Timberline Insulation. We were VERY happy with our choice. Reed's in-home inspection was very informative and we found him to be very friendly, knowledgeable, and easy to work with throughout the process. Their quote was more competitive than the others. He and his 3 man crew were very efficient, tidy, and organized. They completed the extensive job in 1.5 days and were very conscious to leave the area very clean at the end of each day. I give them my HIGHEST recommendation.
