    I reached out to Insulation Nation through Yelp! Josh immediately responded! I was interested in Radiant Barrier as we were still working on can lights in the attic! I had a couple of questions regarding type of product, R value etc & he answered them all so I could do my own research. Josh came out quickly and looked into our attic and with a quick turn around we got our estimate! We were super pleased with it and moved forward! Josh told us there is no Rvalue in Radiant Barrier but after the job was finished we can feel a noticeable difference in the temperature in the house! Choosing Josh and his team from Insulation Nation was a very smart choice for us! When our electrical is fixed we will definitely call him to finish insulating our attic!

    Easy to work with. Good pricing. They were flexible with allowing us to get an electrician in the attic before placing new insulation.

    Also, despite making an error on his end when calculating the estimate, Josh stuck to the price he promised.

These two will…read morecommunicate like professionals be it in verbal communication, text communication, email, and in their professional appearance and composition! That is not the norm when interacting with the trades. My HVAC system had a pipe break and it was leaking water over electrical cords. This was an electrical hazard in the making. The leaky pipe was spilling water all over the play yard of my dog training facility. My team could not use the space, as the water was growing an ecosystem and the dogs wanted to lap it up like a kale fruit drink. Hello giardia! Sean noticed that our HVAC system was not sealed, so we were essentially heating and cooling the outside. They sealed what needed sealing and replaced our air filters. My understanding is that the team primarily does insulation in Denver, so they can help with that, too. Drug-free crew...no meth mouth. Hire these people.

    I couldn't be happier with my choice to hire Mark and make this energy investment in our home. I…read morewish we would have contacted Mark before spending thousands on HVAC upgrades, thinking that would make our home more comfortable. As it turned out, we had lacking insulation in our attic and no insulation at all in our exterior walls. Mark presented us with several options and guided us toward the option that would have the most immediate impact and fit our budget. He filed all of the paperwork for the Xcel rebate. While Xcel took quite a while to process the rebate, it ended up being substantially more than I was expecting and certainly help offset the costs improving the insulation throughout our home. Before the improvements, the second level of our 2-story home was significantly hotter in the Summer or colder in the Winter, than the main floor. Now, we have consistent temps throughout the house and are seeing lower Xcel bills too. Mark and his assistant were courteous and professional throughout the 2-day job and very Covid conscious as well, which was appreciated. Highly recommended!!!

Now, adding to the scores of five-star reviews on Airtight Energy Inspections! Stuart came to do the audit this morning and I was so impressed at his knowledge of how to improve the efficiency of our 1926 Wash Park Bungalow. He even talked me out of spending $15k+ on new storm windows, giving me much affordable options that will yield better results. In addition to all of his recommendations, he is getting me a $40 annual credit with xcel at no cost to me. Among other things, he discovered that our bathroom is venting into insulation in our attic (a risk factor for mold) and that our sunlight needs to be sealed. Will be recommending Stuart to my neighbors!

The lady I spoke with, who's name I've forgotten, was extremely helpful. After spending a bit of time asking questions to understand our project and needs, she went told me that she wasn't aware of the any rebates but that she'd look into it and follow up with me. Later than evening she called me and confirmed there were currently no rebates, and concluded that it didn't make any sense for us to have them audit our home. The way she put it was roughly "we don't like to put ourselves in situations where we can't add value". I really appreciate the honestly and extra effort she made.
