"Why you should upgrade your home’s insulation"

According to the Department of Energy, "Space heating and cooling account for almost half of a home's energy use, making this one of the largest energy expenses in any home.”

As your home ages, your insulation begins to deteriorate - as do the seals around your windows, doors, and lights. Did you know that 50-70% of the energy used in your home consists of heating and cooling? By reinsulating your home, you can save money each month on your utility bill.

A properly insulated home is more comfortable, and the air will stay cleaner. Insulation and air sealing ensures that conditioned air stays inside your home. With poor insulation, your HVAC system works very hard to continuously condition air which seeps in. This air which seeps in is often very dirty and totally avoidable.

The best way to reduce your home's carbon footprint is by reducing energy waste through increased efficiency. According the the EPA, the #1 way to reduce your energy usage in your home is to improve the building enery efficiency through better insulation. Retrofitting can allow new and existing homes to upgrade their insulation.

Have you been in your home and wake up to birds chirping or your neighbor's dog barking outside? Maybe the weather seems louder than it should be. Insulation combats outside noises and also helps with reducing the amount of noise carried from one room to the other.

See what our satisfied Boulder area customers have to say about our service!

John and team were responsive, professional, and friendly. I called John and team and they were one of the only companies I could get a hold of, despite leaving messages with several competitors. John usually handles projects much bigger than the my small insulation project, but he provided a fair quote compared to competitors, and because of his responsiveness I offered the job to he and his team. They scheduled a time and day and showed up on time. Through my own communication error, they were unable to get access to the property and had no way to reach me other than email. They ended up having to leave and when I called them up to explain and apologize, John was understanding, though I would have expected to never hear from them again because of my miscommunication. They agreed to revisit the site in the SAME week. They ended up not being able to complete the project because of structural obstructions. They tried to blow insulation for two hours and they did not charge me since they were unable to successfully fill the space. They were incredibly kind, professional, and honest. I would hire them again in a heartbeat. Many thanks John and team for the five star service!!!"

Koala Insulation of Boulder were incredibly professional from the estimate all the way through the completion of the project. The quality of work was excellent and the crew did a great job of cleaning up afterwards. I would highly recommend."

Stephen
Broomfield County

I highly recommend this company, They are professional and honest. John did an inspection of the insulation in my attic, which I suspected was lacking. There were rooms in the house that were overly hot in the summer and cold in the winter. After the addition of the insulation and a solar attic fan I have noticed a significant difference in the house and couldn't be happier."

John and his team were prompt and professional. They arrived to my home to look at my attic and provide a quote and returned a week later to complete the job as scheduled. I highly recommend contacting them for your insulation needs!""

Koala installed attic insulation for me. Chris worked with me on the details of the specific job i wanted to do for my house. The crew was very professional, clean, and fast. Koala is a new company and they are working hard to earn their business. While they are not certified for the county and xcell rebates. Their prices and scope of work provides similar or better prices compared to companies that need to jump through all the hoops to qualify for a couple hundred dollars of county rebates

Alex E

Chris and his team were very professional. Great communication before hand to all my questions. Chris was on-time for the estimate and the actual work. His team were professional, clean, polite and considerate. They blew insulation in the ceiling, added 2 solar attic fans and also crawled under our newly enclosed deck with 20" of clearance and insulated with batting between all the joists. When finished they cleaned up and left no trace of being there. Thanks Koala"

Although we had a small hiccup with the insulation machine, the installers were very courteous, provided excellent customer service and fixed the issue quickly; they made sure I was happy with the work before leaving. I would use them again and would recommend to others as well.

Koala installed all the foam insulation in our new construction residence.Before awarding the project we asked them to come over and do a walk through with the person who was going to actually do the work, Bernie. For us this stage of insulation was primarily air sealing the upper and lower rims, the stud bays, and the lid, including a 900 sf garage.. We needed to be sure that Bernie was confident about getting the foam to the parts of the construction that were difficult to reach, mainly in the basement and large crawl space. A couple of spots were missed and we called them back: they took care of the problem areas the next day. The house has a whole new feel. We'll follow up in a month or so self installing fiberglass batts. If the foam insulation is not done properly there is no way to really recover from those errors. Prior to the spray work starting he Koala crew covered all the windows and other house surfaces so foam did not spill on them, and they cleaned up well after the job was completed. Be careful about choosing your insulation contractor. We were extremely pleased working with the Koala Team. We recommend them highly.
