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!

Came on time, worked hard and cleaned when they left. This is our second time using them. First for the basement and now the attic. I would recommend this company to anyone.

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!
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!
My wife and I worked with Ben and his team to get our roof rebatted. He did a fantastic job walking us through the process and was extremely communicative. I would highly recommend Ben and LL Insulation for new or existing insulation needs.
