Spray Foam Insulation in Denver, CO

They did a workshop, filled in 2x8 rafters and 2x6 walls. Great price, showed up on time, and did an amazing job. It was completely off gassed by end of the day.

M & G insulated & installed radiant barrier in my 1000 sq ft attic, they did an excellent job and at the best price. The combination of radiant barrier + pink insulation is perfect for Denver summers. My swamp cooler never needs to be turned up to high now. - M & G team know what they are doing, bid the job correctly, have the correct equipment, and were professional. You can trust these guys for a fair price & a quality job. Hard to find honest construction work in Denver & you will be very happy with M & G -

M&G Insulation LLC is the BEST in the industry period. If you're in the front range I would not hesitate to schedule your job with them, don't waste your time getting bids, go with M&G and be done with it.

Very professional and reasonable pricing. My house was built in the 1950s and still had the old insulation which made the winter extremely cold and summers scorching hot, these guys were able to make all the necessary changes to make my home more energy efficient and now I can enjoy my home year round! If I decide to update the insulation in my walls too I won’t hesitate to call these guys again.

Jesse and his team were extremely professional and responsive. This team truly cares about your needs and is here to help. They took the time to meet and greet me and truly understand my insulation needs. They got in my attic in the freezing cold and game me my best option. Pricing is extremely competitive and the level of service can’t be matched. I would highly recommend this team.

Holy Moly this organization is amazing. From the initial estimate to the continuing work they are doing for me I have been nothing but impressed. They were clean, efficient and the staff was terrific.

Korey and her team did a great job! They were prompt, professional, and very reasonably priced. I was referred to Korey from another happy customer and would definitely recommend Koala of Denver to anyone needing insulation work done.

If I could give more than 5 stars to the amazing crew & company I would. I’m so impressed by the professionalism, right from the time of the evaluation & very fair quote, given by Kayla, to scheduling & the final result. I can’t say enough about the crew who did the job! Oscar, Matthew & Jacob were absolutely incredible. They arrived on time, took on what I thought to be a very daunting task of upgrading the entire space, yet made it look like an absolute breeze. They worked together like a dream team, super efficient, professional & paid such attention to detail. I really appreciated their final touch of cleaning up all surrounding areas afterwards. It is rare to find a team and company who comes through like they did. As an interior designer, I will from now on be utilizing Koala Insulation of Denver North for all of my home remodels. I highly recommend, don’t even think twice!

I couldn't be happier with my decision to go with Koala for my home insulation project. Kayla came over to give me an initial quote on my project and she was INCREDIBLY thorough with her initial estimate. She took a ton of pictures, explained what she thought we should do and gave me a detailed breakdown of prices and options. This is after I had a handful of other companies come out to give quotes and they didn't spend anything over 5 minutes before naming a price. One guy didn't even go up into my attic! I decided to have all of my old insulation removed because it was dirty and insufficient. Also, by starting with an empty attic, I could have Koala do an air sealing project for me as well. Andy and Enrique came over to do the removal and they were amazing! They were thorough and made sure the job was done right. I had a couple of weeks between the re-install to do some electrical work, but I had some additional questions come up. Kayla was incredibly responsive to my emails and answered everything additional I could ask. She really made me feel comfortable with my decision to work with Koala. Andy and Enrique came back a couple weeks later and did the air-sealing and re-insulating in one day. They were real pros again and were super considerate and efficient with their work. Those guys are incredible! In the weeks since getting the air sealing and insulation done, our furnace has barely even turned on. Our house is holding heat better and I imagine our bills will be reduced because of it! If you are thinking about getting insulation done for your home, don't waste your time calling anyone other than Koala. Their work is top-notch, communication is excellent, and they even have financing options that aren't an absolute pain to deal with. Kayla, Enrique and Andy are all amazing and I can't recommend them enough!

Fantastic crew and service. Professional, fast and friendly. I would highly recommend.

The quality and professional workmanship of this company is great. I would highly recommend them if you are in need of a spray foam insulation in your home, attic or business.

Overall Great service , I definitely recommend , they have been great to us for years now , they are my go to .

Advanced insulated an hollow interior wall for me which made all the difference in eliminating echoes in my bedroom. I’ve also noticed the heat kicking on less. Jason made the process so easy - he was out for an estimate within 24 hours and had it installed within 48 hours. Most cost effective and impactful update I’ve made to my 1940’s condo!

We couldn't be happier with the incredible service and product we received from Advanced Insulation! Jason shot us straight from the first moment we had him on the phone. He heard our problems, gave a recommendation, and outlined the process. We agreed and they delivered as intended! They removed our old, moldy attic insulation, sealed the attic to bring it up to code, and sprayed in fresh insulation. The transformation has been remarkable—our home feels so much warmer this winter, and we're all coughing and sneezing far less! Their team was professional, efficient, and clearly very knowledgeable about the process. It's made a huge difference in our comfort and overall air quality. Highly recommend to anyone looking to upgrade their home insulation! Thank you for the excellent work Jason and crew!

I couldn’t be more impressed with Advance Insulation Solutions. From the initial consultation to the final installation, their team was professional, knowledgeable, and efficient. Jason took the time to explain my options, answered every question clearly, and delivered exactly what they promised, no surprises, no delays. The quality of their work speaks for itself. After the insulation was installed, the difference in comfort and energy efficiency in my home was immediate and dramatic. The job site was left spotless, and they clearly take pride in their craftsmanship. What really sets them apart, though, is their commitment to customer service. Jason and his team were responsive, respectful, and genuinely cared about doing the job right. It’s rare to find a company that combines this level of expertise with such great communication and professionalism. If you’re looking for insulation done right, Advance Insulation Solutions is the team to call‼️ Top-notch work, fair pricing, and a company you can trust. Highly recommended!

We recently had REenergizeCO perform a Home Energy Audit, and we were extremely pleased with the results! Marissa did a fantastic job with the audit--she was very knowledgable, worked quickly and efficiently, and was very friendly. (As an added bonus, our dog fell in love with Marissa and she might be his new best friend.) The report that we received was helpful in identifying improvements that we want to make to our house to make it more energy efficient, and we appreciated receiving an associated quote to perform the suggested work so we had an idea of how much the upgrades would cost. Overall, we would definitely recommend working with REenergizeCO, especially because of Marissa's great customer service!

Following an energy audit I came across this Xcel Energy registered company. Dexter and his team did a great job upgrading the insulation in our attic to current standards. They were the only company that offered to squeeze into two lower attic areas to also address the insulation there. The team was technically strong, very friendly and considerate, overall everything worked out very well. Two areas that required follow-up: - attic hatch - rather than just increasing the insulation, as proposed, we decided to completely redo the hatch - dam - single wall cardboard was used around the furnace, that does not hold up to physical impact during routine maintenance work in that area. Particle board as used around the hatch should have been specified Costwise Reenergize CO was the highest of 4 quotes, but they also were the ones that were most flexible.

I waited 2 years after getting my solar to write this because I wanted to make sure the company resolves problems that arise post-installation. They do. They have always been super responsive. Also, they just seem like nice people who are not out to steal your money. I noticed this the first time I met one of them. He came to the house to test whether for air leaks and other energy losses. In the end, he told us our house is in great shape and didn't need any work. How often does a contractor tell you that? They installed the solar over the course of two weeks. We had a panel go off line a few months later. They came out and fixed it within two weeks or so. We had a wifi disconnect, they came out to fix that too. No fuss. Great company.

I have been remiss in leaving this review but the hotter it gets, the more grateful I am for Robert and his team. I started with 1,000 SF of attic space and an R rating of about 10. Robert recommended R60 for Denver. His team came in over 2 days and removed my old insulation, sealed the attic, blew in new insulation. Everything was efficient, clean, and as unobtrusive as possible. Additionally, Robert completed a handful of other little things that needed done in the attic and installed more vents. All that is enough reason to hire them but my house is staying so much cooler. My evaporative cooler is keeping up better. We have yet to put in the window AC unit and every room in the house is more comfortable. Then, Robert filed for the rebate with Xcel. I didn’t have to do anything. Please hire this team. They are worth it.

Had our attic sealed and insulation re-blown. First, if you’re considering it, do it. Makes all the difference - your rooms are not just warmer, but temperature is much more even. Not something you can get by just blasting the furnace. Robert and his team were great. He himself was on site everyday and doing the work, and ensuring his team was being thorough. He’s also just extremely knowledgeable and thinks of things none of the other 3 companies I got quotes from did. And he was the only one to actually go in the attic to build a quote, which is a big deal for me. We found a couple issues he built a plan around fixing the others did not.

Simple Home Energy Solutions/Robert (owner) and his team were very professional, timely, communicated well and prompt with any questions or concerns. We recently had an insulation replacement in our attic and air sealing which went smoothly and performed to high quality standards. I would highly recommend Simple Home.

Excellent attic insulation removal and upgrade experience. Corrie did a thorough inspection, providing photos of all the key areas in the attic that needed to be addressed. Walked me through the various insulation options - and notably I did not feel pressured to go with the most expensive solution - she indicated for our type structure it wasn't the best path. On the day of the install, the team was on time and knew exactly how to proceed. Minimal interruptions, and again when complete, they provided many photos showing before / after. Team also performed the tests needed to qualify for the Xcel rebates and everything passed successfully. Excellent experience overall - highly recommend.

We had a great experience with Koala Insulation for our attic insulation project. Their team removed the old insulation, sealed up air gaps, and installed new insulation up to the recommended levels—including in a tight, hard-to-access attic space. From the start, they offered multiple options and quotes, were responsive to all our questions, and communicated clearly throughout. On the day of the job, they arrived on time, worked efficiently, kept everything clean, and made sure to explain every step of the process. Even the blower-door follow-up was scheduled quickly. Every person we dealt with was professional, patient, and knowledgeable. Now that summer is here, we're already noticing reduced heat in the house and enjoying the energy savings. Highly recommend Koala Insulation if you're looking for quality work and great service!

We called to get some more information and just overall help. Corrie was extremely kind, professional and quick with answers. She even did some calling around for us and helped point us in the right direction instead of us going down the rabbit hole ourselves. Amazing service thank you so much!

I had Level Up remove mold and install insulation in both my attic and my basement, and the entire experience was excellent from start to finish. The team arrived on time, explained the work clearly, and showed real attention to detail throughout the installation. They kept the space clean, worked efficiently, and made sure I understood everything they were doing along the way. The difference in temperature and comfort was noticeable right away. It feels great to work with a company that truly cares about quality and customer experience. I would gladly recommend Level Up to anyone looking for reliable and professional insulation work. Sagi was super friendly and easy to work with as well!

Level Up Insulation was contracted by my pest control service, Saela, to mitigate a mice & rat infestation in my home's crawl space. Two technicians, Afren and Alberto, removed all the contaminated wall insulation and the ground moisture/radon barrier in the crawl space. They sanitized the crawl space, then installed new wall insulation and radon barrier over the ground. They bagged all the contaminated materials and disposed of it all without leaving a trace behind (they protected the basement living area and 1st floor hallways with plastic sheeting). Afren and Alberto were friendly and professional, and super hard-working. That job would've taken me a week, and they banged it out in half a day. The finished job looks amazing... clean, bright and fully sealed. I highly recommend Level Up Insulation, as well as Saela Pest Control.

I hired Level Up Insulation to top up the insulation in my house. Scheduling the estimate was easy, all my questions were answered, and the price was excellent. After approving the estimate, the installation happened within 2 days. The technicians from Level Up were very professional. Installation took about 3 hours and at the end, they walked me through the results. I'm very happy with the work that Level Up installation did and would definitely recommend them.

USA insulation did not disappoint from the first friendly talk with Jessica to the bid from Kelly to the 2 professionals who installed the product. Everyone was easy to communicate with and professional while doing an awesome job. I recommend them for sure.

We had our basement and attic insulated. Dustin and his crew were fantastic from the initial visit and estimate until completion. His team was courteous and professional. Recently, we had issues with condensation in our bathroom. We were unsure what to do and when we contacted Dustin, he immediately responded and came to make sure it wasn't a problem his team had caused. It was not their problem, but he explained what is wrong in our bathroom, took pictures, told us what needed to be done and was even willing to help refer us to someone he trusted. We would positively refer him to anyone who needs insulation done. Lloyd and Darcy Thomas

The crew showed up on time and got right to work. They answered our questions, went over the process/expectations, and left our home clean! Highly Recommend!

Great company to work with. Very responsive to inquiries and quick to get us scheduled. We’ll use them again and we highly recommend them. Photo is just 1/2 of the ceiling before all was completed, we also had them to the walls in our pole barn.

We have used Mucilli Brothers twice now and had great experiences both times. George and his crews are very professional, thorough and clean. Our 2nd house has an access to the attic in our master closet and the crew took the time to wrap the opening with plastic in a way that nothing in the closet got dirty. The Insulation portion was done correct with the cleaning and replacing the aid dams for the soffits, sealing penetrations and damming around electrical boxes for ceiling fans, etc. I would recommend Mucilli Brothers to everyone.

Super impressed by Mucilli Brothers insulation. I was referred to them by a coworker who also had a great experience. They gave a quick estimate based just on pictures/floorplan of our house, scheduled us quickly, were responsive and proactive with communication, and did a great job on the actual work. Thank you George and team!!!

Best possible experience. Estimator came out right away and the crew arrived even early the next day. They were fast and efficient and did the expected work in no time at all, even cleaned up so that you would never know they had been there. Superior service.

These guys are fantastic. I had them come in to blow insulation into my 1980s home between my main floor wood floors and my basement ceiling. It no longer sounds like my kids are a herd of elephants and I have the unexpected benefit of not having to use as much heat in the basement. The technicians were all courteous and the company was great to work with.

Devin was super flexible and worked around our chaotic schedule. The spray foam in our crawlspace has made such a huge difference for our house—the downstairs is no longer drafty at all (and it used to be very drafty). I’m a bit OCD and noticed a few places where the foam was a tiny bit scant, and Koala came out right away, no questions asked, to spray more foam. They truly did an amazing job and I would highly recommend Koala Insulation.

Project Manager Tyler is great to work with. Crew was polite, professional, efficient and fast. There isxa noticeable difference in our upstairs now with the new insulation. We will use their services again in our rental unit.

We had Rocky Mountain Retro Foam do our living room on the main level of the house. Before we did our HVAC system could never keep up. When set at 71 the main level would get warmer throughout the day instead of colder. It would run so long our Ecobee would send us a message saying our system wasn’t working properly. Now with just one room on our main level done, our HVAC system can not only get the house down to the desired temperature, it actually shuts off once and awhile. I have attached pictures from our Ecobee home IQ. The picture are almost exactly a year apart, and I don’t think the foam had even fully cured yet. It’s pretty amazing to feel the difference and then have actual stats to back up what we were feeling. I can’t wait to get to he rest of the main level done and then start on the upstairs.

Crew was efficient and thorough and gave me good advice for an additional DIY step I could take to protect even further a problem overhang area. Immediate results made an old addition the same temperature as the rest of the house for the first time. Site was clean at the end despite a lot of drilling and surplus foam during the process.
