Energes did a great job with the foam on my shop! They were professional and prompt to deal with. Orlando was up front and honest with pricing. The guys showed up on time. They took care not to overspray on anything that was not intended to be insulated and made the experience a good one that I highly recommend to anyone needing spray foam insulation. Also, it really is amazing the difference between spray foam and regular insulation. It has all but eliminated sound from outside and my heater barely runs on cold days.
Very nice company to work with. Prices are reasonable and they did complete the work prior to the date promised.

Rapid Raise foamed the interior of the garage rope and gable ends of the garage roof and the same for the interior of the main house. Heating and cooling bills both decreased. Less kilowatt hours and less heating natural gas usage were noticed. I would recommend using Rapid Raise for their prompt service and the professional customer service.
Rapid Raise and Sprays insulated my attic and the difference is incredible. I have an older home that had no insulation anywhere. I can't wait to have the exterior siding done next!! Thanks Carter.
They raised my back patio that had settled about a year after we moved in. The water doesn’t sit on the patio anymore and I can’t even tell they drilled holes in it! Definitely will be having them some back to do some foundation raising in a few sunken places in the basement and will be getting deep foam injection done before we pour our driveway pad so we don’t have to worry about that sinking on us.

I just received attic insulation from Arvada Insulation. I'll save you the time on shopping around, Arvada Insulation was the most competitive quote by far. I was new to the attic insulation process, so I received quotes from several other vendors in the area to get a baseline. More importantly, Phil was very easy to work with. Friendly, honest, and straight to the point. Phil gave me a quote, and maintained the price throughout. Even after making several repairs and modifications to improve the integrity of my attic beyond the insulation. Vic was also nice. He enthusiastically showed me how the fiber glass hopper worked. Phil was careful to keep the work area clean, and the fiber glass insulation was not as dusty or messy as I would have expected. I will be recommending Arvada Insulation to anyone in the area :)
I had a great experience with Phil & Arvada Insulation. One of the bedrooms in our 1959 house was always colder in the Winter and warmer in the Summer. Now that it was a nursery for our baby boy we needed to do something about it. After trying a new vent and cellular shades I decided it was time to try to get the walls insulated, which felt like it would be a daunting (and expensive!) task. I called Phil from Arvada Insulation because I knew he was local to my neighborhood. Phil talked me through his process and my options to blow in insulation into the walls then scheduled a same day estimate. He was right on time for the estimate (though I almost napped through it) and throughly reviewed the room inside and out then provided my options and a hand-written estimate at a shocking reasonable price. I was hesitant about how my exterior brick/mortar would look following the project and Phil went the extra mile by showing me some other properties where he had done similar work and creating a new mortar sample just for me. On the day of the project Phil again showed up on-time, was respectful of my property, and did an extremely professional and thorough job. The best part is that it actually WORKED! My baby’s nursery maintained heat 3-4 degrees better than it had before which is such a huge relief. I highly recommend Phil & Arvada Insulation and will most definitely be calling him for future insulation projects.
After getting a great quote from Arvada Insulation for my attic insulation job, I accepted and got scheduled quickly. It included the sun room which another company had missed. I was impressed with his knowledgeable approach, and how good the results were. Thanks Phil and Vic, I will be recommending you in the future!

These guys were fantastic. I knew the insulation in my attic was low (around 6–10 inches), so they came out, assessed the situation, and provided a quick, clear estimate. I considered doing it myself, but for just a bit more money (and a lot less time and hassle) it made so much more sense to have them handle it. I'm glad I did. The upstairs temperature has dropped by about 5°+ on 90° days, and now it's roughly the same as downstairs which is huge for my A/C unit and electric bill.
Koala Insulation did a fantastic job upgrading the insulation in our attic and other parts of the house. They identified key areas for improvement, and the project plan earned praise from our home energy advisor. When it was discovered on the day the work was to take place that an issue with construction of our house prevented the project from happening as originally planned (and bid), Koala worked to troubleshoot the issue and provided us with a compromise solution that was fairly priced and still allowed for maximum insulation benefit under the circumstances. The Koala team who did the work were friendly, professional, and great to have around. They finished the job quickly and cleaned up completely afterward. We’re looking forward to greater comfort and energy savings this winter!
Absolutely the best service! A year ago we needed to replace a room of insulation for mice mitigation. Koala helped out. They were very professional, on time, and efficient. We decided to finish a bathroom in the basement. So, I called to see if they could do the same thing a remove and replace the insulation. I talked to Justin, and glad I did. He was immensely helpful. He gave great advice and actually did something most businesses don't these days. He actually said the price to do this would be more expensive to go with them, and walked me through how to do it myself and save hundreds! What business wouldn't just accept the job and make me pay hundreds more without realizing it? Koala Insulation of NoCo we appreciate all of your advice and will continue to recommend your services!

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!

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.

I made a phone call, and the next day the crew showed up on time. He gave an estimate over the phone that was in my eyes fair and comparable. My wife was home for the work. When I got home I checked the work and I had questions, the crew did not do an efficient job. I called back and the following week a different crew showed up and corrected all my concerns. They were respectful of my home, on both occasions. As far as quality control, lacking a bit, but I am a firm believer in small companies.
Received quote for work. Agreed to work and set up a time for work to be done. The guy that did the estimate was very friendly. The guy I spoke with on the phone to setup work was short with me both times I spoke with him. Scheduled my work around it’s completion company never called or showed up to complete work I called twice after waiting around all morning finally decided to leave to go get my other work done. Still no return phone call.
