I do not write reviews very often, but I recently had a very good experience with Green Factor and in particular I wanted to give credit to a number of their team members. I recently had Green Factor convert my attic from fiberglass insulation to foam. Clint, who is one of their sales representatives, very promptly replied to my request for a quote and offered me a detailed plan. Adam and his team, who did the work, left behind very little for me to clean up, which is a sign of how careful they were. I should also mention that Stephanie was very gracious and communicative when scheduling the work. As the home owner, I am very satisfied with Green Factor's work, as it has transformed my attic from a place that I was reluctant to set foot in, to an attractive space.

We got 3 fireplaces from Hinges when we built and their prices beat the other guys by a ton! They were easy to work with on install as well as call-backs for the punch list. Today I was having trouble dismantling fireplaces to clean them, and Cyndi at the front desk took the time to walk me through, and even had me send pictures to her personal cell so she could help me. She could have easily had me make an appointment for a service call a month from now, but she didn’t. I highly recommend these guys!
As a builder, Henges is our preferred insulation company. Larry and Doug make scheduling a breeze. Their installers show up on time and ensure there are our houses are insulated to meet energy efficiency standards time after time again. Their crews are professional and trustworthy. If you're needing any sort of insulation solution, I highly recommend you give them a call.
Couldn’t have had a better dealing with Henges, called and had a quote the same day. Was contacted the following business day for scheduling and they actually came the following day to insulate. Great commendation and fair priced. Workers were courteous and the final product looks awesome!

This is my second experience w Black GOLD. Blake, rep, thoroughly explained my insulation options, needs and price. The installation team was on time, professional, neat, got right to work determining best attic approach. Done in an hour. These folks are pros, easy to talk with and very responsive. Great value for my needs.
Thank you for reviewing my review. I am actually still waiting for someone to get back with us on adding some insulation above the garage. An associate came out shortly after the build and we noticed some spots where you could see the sheet rock between the trusses and they were going to get back with me on getting this corrected. I know everyone is extremely busy but if we could get this completed, that would be great. You should have my information on file. Thank you again.
I reached out to Black Gold to get some more insulation installed in my house. I was put on the schedule less than a week out and everyone I spoke to was helpful and knowledgeable. The install took less than 1 1/2 hours and the workers left no mess and took before and after photos for me. I would highly recommend going with Black Gold for any insulation needs. Blake was very helpful with the scheduling & Michael and Reynaldo were great installers.

They went above and beyond our expectations! Would definitely use this company again, both affordable and quality of work was good. We hired them for a "new construction insulation" up to code. They were very fast and did an excellent job
I was paired up with Williams through an energy audit provider for Evergy. On the morning of my insulation, Williams called me to confirm timing. I attempted to confirm the services being provided when they informed me the intermediary changed the services so they could do half (kneewall overlay) and Williams would do the blown in part. This didn't make sense to me as once you blow in the new insulation you don't want to disturb it. In the end Williams went above and beyond making sure I was taken care of and even recommending additional areas that could use more insulation that were not on the audit report. I would highly recommend Williams for your insulation needs.
Do not use this company. They have put us behind over three weeks because they never show up.
