"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.

James and his team did an excellent job at our place. His customer service was top-notch. We had our attic insulated, and it turns out to be a complex and complicated job, but James and his team didn’t hesitate in giving us support and working hard to have it perfectly done.

Solar Power Attic Fan

I spoke to three companies. Jacob at Koala gave me the most informed recommendations for keeping my house cooler. I’m already saving money!!! The installers who blew in insulation were professional, friendly, and clean. My house was left immaculate. I also installed an attic venting fan. The installation process was perfect. Again it was professional and immaculate. I highly recommend this company.

Denver

It was very hard to find a company in Denver that would do a smaller insulation job at a fair price. Koala insulation was wonderful to work with, fairly priced, on time, and responsive. I would recommend them to anyone and everyone!"

Denver

Free Estimate

They were honest about us actually not needing insulation which was both a huge relief and confirmation that this business is reputable and actually cares about their customers. Especially as I had two other bids who came afterwards and they tried to sell us over $1000 in insulation that was not needed. If and when we do need insulation, this company has earned our respect and would absolutely earn our business.

Aurora

Crawlspace Encapsulation

Crawlspace insulation and encapsulation work was completed. Crew was friendly, professional and did a great job. Will definitely be using them again on future projects.

Denver

Blow in insulation

I just had Koala come and spray-in insulation in an upstairs bedroom and could not be more pleased with the whole process. Everything from the quote to the actual install was communicated to me in a timely and concise manner. No hidden fees or upsells, just exactly what I asked for. On the day of the install, the two techs were extremely professional and cognizant of the fact that my wife and I were working from home. After they completed their job, they left the room just as clean as before they started. On top of all this, they beat out several other insulation installers by quite a bit. I would definitely use again and recommend Koala!

Denver

Attic Fiberglass Blow in Addition

Great team and crew Really effective and a great value. I'd definitely recommend.

Denver

Living Area Ceiling & Garage ceiling - Blown-In Insulation - Fiberglas

Jacob was great to work with. He communicated well and stuck to his word throughout the entire project. He explained the process and their product. I was quoted a good price and he still made adjustments after they had completed the work due to unexpected work that did not need to get done in a specific section after all (Not their fault). He and his guys were on time the day of the job and got done on a timely manner while not rushing. Once done, they were really good about cleaning off and clearing the path to my furnace which is in the attic where the insulation took place. Any additional mess in the main living space was also cleaned up which I appreciated. I would recommend Koala if you're looking for a reliable company for a fair price.

Aurora

Presented a competitive cost for the insulation work to be done. Very thorough and professional; knowledgeable installer went out of his way to be sure I was satisfied with each phase - blown-in insulation in exterior walls which required accessing the walls from inside as we have a brick exterior, and blown in insulation in the attic. Cleaned up all the drywall dust and insulation; covered all the furniture, etc with plastic sheeting.Very pleased with the final result; house is definitely warmer without furnace running frequently.

The team was a joy to work with. Sean always got right back to us when we had questions and walked us through everything every step of the way. The added insulation will help the house stay warmer in winter and cooler in summer, and it's already much quieter. We live next to a busy street, so that's very important to us.
