We had a great experience with Koala Insulation! They came out to add insulation to our attic and also installed a fan in the roof. Our top floor has always been noticeably hotter than the rest of the house, and after their inspection, they explained that our insulation was below the recommended standard.
They were very knowledgeable and took the time to walk us through what was going on and how improving the insulation, along with adding the attic fan, would help regulate the temperature and keep our A/C and heat from escaping.
The team was professional, efficient, and left everything clean when they were done. We’re already noticing a difference and feel much more confident heading into the hotter and colder seasons. Highly recommend them if you’re dealing with uneven temperatures in your home!

We hired Koala Insulation of DC to spray foam our attic as part of a home renovation, and I honestly couldnt be happier with the decision. From start to finish, the experience was smooth, professional, and stress-free, which is exactly what you want when you already have a renovation going on.The team showed up on time, walked me through the entire process, and explained why spray foam was the right choice for our attic space. As a homeowner, I really appreciated that they didnt talk over my head or rush through explanations. They were patient, knowledgeable, and clearly knew their craft.The work itself was done efficiently and cleanly. They took care to protect the rest of the house and left the attic looking exactly how it should: sealed, insulated, and done right. Since the install, weve already noticed better temperature control throughout the house, and the HVAC isnt working nearly as hard. The attic feels like a completely different space now.What really stood out was their attention to detail and pride in their work. It felt like they treated my home the way theyd treat their own. If youre renovating and considering spray foam insulation, Koala Insulation of DC is absolutely worth it. Five stars without hesitation.
