We previously got a quote from a company that was really hard to get through to.

The employees that arrived were professional, helpful, courtous, and highly competent. I recommend!

Guardian helped us with a huge insulation project this past week and they were fantastic. We live…read morein an older ranch that had very minimal to no insulation and we were struggling with heating and cooling our home for many years. After shopping around they were able to give us exactly what we needed and we already notice a difference with the mini heat wave that we are having currently here in Denver.Scheduling was relatively easy and we were able to get on the calendar within a month. Pricing was competitive and they offered to price matching should we find another company that we liked. Other companies, however did not offer as many services for the amount that we paid. Guardian is also filing our upgrade with Xcel energy so that we get all the offered rebates that we don't have to do that ourselves, which is definitely a nice touch. The installers arrived in a timely manner, and were done within one day with a job that was estimated to take two. They also kept things tidey and cleaned up once finished. We also had a ton of questions and Brian, who helped us, was always able to reply and patiently explain things. He was incredibly flexible with planning to our unique situation, and was very knowledgeable. From the beginning, he gave us a bunch of literature, as well as testimonials, and a résumé for the company which definitely put us at ease at the level of experience that was held by Guardian. I would absolutely recommend Guardian for any insulation needs that you may have for your home; And I wish I could say that we would use them again, but I think that our problem is thankfully solved all thanks to them.

I requested a quote from several companies, the first one didn't even take any measurements or look…read moreinto the attic and gave me a quote. Then next one that came looked in the attic and took measurements before giving a quote. When Brian with Guardian Insulation arrived, he took the time to understand why we wanted insulation. He explained the work they would perform, even sealing all places, like electric line holes in the walls to prevent air leaking in or out of the house. He showed how this would apply for a rebate Excel Energy, and we received a $600.00 rebate too. They also provided an energy audit checking for air leaks in the house, before and after the work. The price was competitive with the other companies and the work was performed in a professional manner, cleaning up before they left. I would highly recommend this business.

When I reached out in May for an attic insulation project estimate, Francisco was so responsive and…read moreset up a time to stop by and take care of the estimate within a day. Unlike some of the businesses we'd contacted, he did more than pop his head into our attic space and give us a cost. He carefully examined our attic space so that he could not only gauge how much insulation we needed but also how to best air seal the attic to increase the insulation efficiency. His final quote for the project was reasonable, and we arranged for a date and time for the project to occur. Not only was the crew on time, they completed the project as promised and were respectful of our living space, doing their best to minimize attic dust and grime from escaping into the main floor where we live. Thank you, Francisco, and your crew for completing the project on time, as promised. Your professionalism and commitment to seeing a project through successfully speaks volumes about your business. I wish you all the best and have already recommended you to other people I know who are in the market for home insulation.

Since then, I have referred hundreds of customers to this place over the years with my Window Company JDI Windows. All customers say they are knowledgeable, have more sevices for energy audit issues, and prices are very competitive. When it comes to blowing cellulose in walls or attics or thermal barriers for crawl spaces or insulating around canned lights, Bestway is who I recommend to everyone trying to seal up their home.

A few of our neighbors heartily recommended this place but for the life of me I don't know why. It…read morewas worse than pulling teeth for them to get back to me (they never did, I finally got 'lucky' and someone answered the phone), but then they never showed up, TWICE, no phone call and no apology. Instead, I got an earful how 'Steve' got no work done because he didn't adhere to his schedule and went to the wrong address. ??? Why do I care? I don't. Five hours after the fact and 'Steve' didn't check in with the office, and the office didn't reach out to say 'Oops, we did it again.' Not getting a third chance to not show up. **For a quote.** Imagine if we'd scheduled to do the work with them? As if. rec'd this defensive, unprofessional response from the owner, Debra W., who continues to demonstrate customer service doesn't exist at Bestway, although she did make my husband laugh aloud at her, so there's that positive, I suppose. "We aren't perfect and never said we were. We have been working 14-18 hours a day. I personally I have had 3 days off since the fires. The crews have had one day off a week. We are tired, we are exhausted, but we are trying to do the best we can. As a resident of Lafayette, and Louisville we are not gouging our neighbors like other companies. And we get alot [sic] of complements [sic] every day. So we must be doing something right. We don't make you sign a contract and we get the highest results out there so you are free to go with who ever you like." We did go with another firm, NetZero, who had excellent customer service, showed up every time they said they would, doesn't have one "sign a contract," has received numerous compliments and recommendations from our neighbors here in the Marshall Fire impacted neighborhoods (Superior and Louisville), did all the paperwork for us with the rebates, and charged a fair price, no gouging. Tip to Debra W.: next time you get a negative albeit honest review, instead of lashing out at the reviewer, take a moment to really read it and see what you can take away from it. If you still feel moved to reply, instead of being ugly and defensive, maybe say how sorry you are about the two no-shows and the poor customer service, that you are exhausted, etc., although that's no excuse, and you're sorry this customer slipped through the cracks. You can add that as a Lafayette resident you take treating residents of Louisville and Lafayette (and hopefully Superior, Broomfield, Erie) fairly. You didn't choose that path this time, perhaps you will the next.

Absolutely horrible customer service and a very disappointing experience…read more During an energy audit, my hardwood floor was damaged. I also discovered that the technician moved my security camera from the window to a table without asking. This was captured on my security footage. When I raised these concerns with management, I felt they were dismissed. The manager told me he believed the technician's account over mine despite the video I provided. I also informed him that I intended to leave an online review. During our conversation, he responded by saying, "I'll sue you for defamation." And, " I can't wait to see everyone on Reddit laugh at you" That response made me question whether customers feel comfortable leaving honest negative reviews after receiving that kind of warning. Based on my experience, I cannot recommend this company. I encourage anyone hiring these contractors to have security cameras and to document the condition of their home before and after service. In my opinion, moving a customer's security camera without permission is a serious security concern. Xcel's website has a list of companies you should use I'll provide a list below. With only 140 reviews on google and 21 on yelp the business has been in business for 17 years he says. Yea a lot of people love your business

We purchased a new home in '21 and knew we wanted to do at least three things right off the bat: 1)…read moreinsulate the attic, 2) install solar, and 3) an EV charger. I was pleased to find that REenergizeCO did them all and were more than just an installer but on mission to increase energy efficiency. From start to finish communication was fantastic. They first did the insulation and we noticed a difference almost immediately. They also took care of submitting the Xcel rebate paperwork for it. The solar panels and EVSE came a bit later. Again, they took care of all the paperwork with Xcel. The system has been working without flaw since and saving us tons of money in this inflated energy cost environment. We had them out recently to detach and reset the panels for a roof replacement. They took the opportunity to slightly tweak the layout for better efficiency. Still the same commitment to quality!

He was more thorough than the other companies I interviewed, cost was appropriate, but more importantly he knows his business and is local. An architect friend gave me his contact. What stunned me about most of the contractors is they do not have a imaging camera. I happened to have one, imaged my home prior to having a different contractor work on my home, and afterward found that not only had he not filled all my walls, did a lousy job cleaning up, but hadn't even mentioned that he didn't do interior walls for my garden level basement although it needed to be done. My bad for not reading the contract closely. I assumed that if he was going to insulate my home he'd do it all (or at least tell me what he wouldn't do). Thermal Craft came in and finished off my home and I'm really pleased.
