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!

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!

Did a fantastic job insulating my garage while adding an exhaust fan. They subcontracted out the drywalling which could have gone better though. Four and a half stars rounded up.

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.

Ascend insulated the cantilevered areas of our home, the floor over the garage and knee wall area above our garage, as well as the rim & joist in part of the basement. We were very satisfied with the workmanship and cleanup. They’re very easy to work with and very helpful.

Ascend construction was great to work with. The whole team was polite, prompt, communicative, and attentive. I felt like they really took the work seriously and wanted to do the best work they could. The crew took great care while working in our home for three very hot summer days and they did a great job. Would highly recommend them to anyone looking for insulation/air sealing work. They've also been very helpful in ensuring we will get rebates through Efficiency Works.

OMG....Ascend Construction came to my home and re-insulated my entire house. They did an amazing job. I had no idea how thorough and how much work was needed to complete this project. All communication and scheduling from Chris was excellent. Shad and the other technicians were so professional, very respectful and polite. They answered all my questions, worked extremely hard and cleaned up each day. They went above and beyond my expectations for this project.I highly recommend Ascend Construction for any home or business services you need.Sally Gunberg

Ascend Construction was recommended to me by another insulation contractor. They were easy to work with in regards to bidding the job and scheduling. This was for insulating a cabin attic in a semi-remote area. The crew arrived as scheduled with all the equipment and material needed. The job was finished in a few hours to include a full cleanup of the area. Everything was handled in a completely professional manner to include photographs of the completed work.

I hired Ascend Construction to complete energy efficiency improvements to my home. They showed up on time, worked diligently, and showed genuine care for my property. They placed protective coverings where applicable, and vacuumed after their work was complete. A before an after blower door test showed a 30% increase in air sealing...which is significant.I recommend this company to anyone looking to save money on their monthly utility bill, or improve the climate comfort of their home.

Ascend installed a radon mitigation system for me. Unfortunately, where they installed it resulted in my washer and dryer being out too far so I couldn’t open my laundry room door all of the way. With some negotiations, Greg sent out his crew to get it remedied without additional cost to me. It’s now in an obtrusive place and I can use my laundry room again! Dana (their office manager) has some of the best customer service I’ve experienced and I felt very understood and taken care of when I explained my issue. I am happy with the end result! Thank you for having a business with integrity!

Greg and his team has installed vapor barrier in several of our cabins. Some of which the crawl space are very tight spaces. They are professional and extremely polite. If you are in need of vapor barrier, these are the guys you should call.

I contracted with Ascend Construction after Fort Collins’ Efficiency Works program audited my house and suggested insulation & sealing for attic, knee walls, and floors (and misc items). I have confidence in Fort Collins programs, so felt comfortable using their contractor Ascend and was not disappointed. I had a great experience with the Ascend team in terms of communication and expectations. Wife and I work from home and we have kids, so we were pleased with the communication in regards to concerns we had around that. In addition to the team being really friendly and competent (taking before/after pictures, answering my questions, paying attention to detail), I want to compliment them on cleanup and putting things back (rolled up rug in garage was hung back up, I didn’t have to sweep up screws, no insulation mess in closet, etc). I just had the project completed, so a small rebate and updated air leakage measurement are forthcoming. Qualitatively, I feel there is an improvement when I take stairs to the 2nd floor (the temperature change from 1st floor to 2nd floor is not as noticeable) which will be a nice comfort improvement and financial savings.

Worked hard and did a great job. Really easy and positive experience.

Greg and his crew (Chris, Dana, and Jack) at Ascend completed items identified in my EPIC Homes home efficiency assessment (highly recommended, John Fassler is terrific) that included sealing my crawlspace, ducts, cantilevers and adding insulation in my roof trusses and between my garage attic and house. They achieved a 44% reduction in air leakage, from which I hope to benefit in reduced energy, utility savings and comfort. They were super friendly, attentive to all my questions and concerns, efficient, and did fantastic work.

We had more insulation added to our attic, had a whole house fan installed. We had a passive radon system converted to an active system by adding a fan. The work was professionally done by two extremely knowledgeable and professional people. What I really appreciated was the young women on this two person team and a company that gives opportunities in this energy saving company to women. I am here to say that the job was done perfectly, on time and the proof is a functioning energy saving system. We highly recommend this company without reservations.

Ascend Construction did an energy efficiency upgrade to our house as part of the City of Fort Collins EPIC program. They coordinated the work well with the findings from the program. We liked the responsiveness in scheduling and minor adjustments. They were right on time, explained every step and did each step accurately. The addition of a whole house fan looked nice and integrated well into our living room. The final airflow parameters (sealing) improved significantly which showed that they did an accurate job.

We live in Old Town Fort Collins in a home built in 1900. It has great airflow, but no air conditioning. And since we have radiant heat, we can't install central air. We were looking for an eco-friendly alternative and did some research on whole house fans. A lot of our friends have one but say they aren't satisfied - their fans are too loud, not efficient, or don't cool the house. We called Ascend Construction and Greg Marshall came to our house. I knew immediately that we had the right contractor. Greg was very familiar with old houses, talked us through the process of ventilating the attic, and recommended the AirScape whole house fan. We scheduled the work, and Chris did an amazing job getting the fan and attic vents installed in just one day. We absolutely love our AirScape fan! It is amazingly quiet and efficient. We can immediately feel the house start to cool down when we open the windows and turn on the fan in the evening, with a nice, gentle breeze. We leave the fan on all night, turn it off and close the windows in the morning, and the house stays cool all day. The entire experience far exceeds our expectations, and now we can't imagine living without our AirScape. I highly recommend Ascend Construction.

From start (getting a bid) to finish (job site left spotless after the work was complete) working with Ascend was fantastic. They were responsive, clear in their communication, friendly and thorough. I would most definitely work with them again.
