Spray Foam Insulation in Santa Monica, CA

Ronny installed radiant boards across our attic before laying new insulation. I liked how he explained the airflow path from the vents to the ridge. After the work was done, the whole upstairs cooled off without needing a new AC unit. It's simple but effective if you get it done right.

I have a large older home with tricky attic framing. McGrefor Insulation’s team used a combination of batt insulation and spray foam to make sure it was airtight. They were fast and polite and made it feel like a new space. Our heating bill has dropped, and our home has become more comfortable. That alone made it worth doing.

We are generally happy with the work the guys did and respectful of our home. Thank You!!

I just love watching this team work. They move with efficiency, take their time with careful, detail-oriented work, and it is super obvious that they are pros. The final insulation job is perfect and now the whole house holds heat so much better. My AC finally gets a break.

The insulation crew was so neat. They cleaned up the attic before and after they did the blown-in insulation, finished the job quickly, and didn’t leave a single piece of material outside the attic. Super clean job, and the people were professional.

The project manager laid out the project scope, and the team executed the insulation installation perfectly. Truly professional and committed to a high R-value.

I had an outstanding experience with this insulation company from start to finish. From the very first call, Rafael set the bar high—he was not only prompt, courteous, and professional, but also patient in answering all my questions and making sure I felt confident about the process. He truly set a great tone for the entire experience. Giovanni and his team were exceptional—arriving early, setting up tarps to contain any mess, and working efficiently while treating my home with care. When they were done, they went above and beyond with cleanup, leaving everything spotless. I can’t recommend this company enough—professional, thorough, and genuinely dedicated to doing the job right. Thank you, Rafael, Giovanni, and David, for the amazing work. I’ll be recommending you to neighbors, friends, and family without hesitation.

Govanny is the BEST!!! He and his team at Koala went way above and beyond. Our attic was in really bad shape and Gio and the crew did an amazing job removing all the junk, cleaning up and installing new insulation. He even helped out installing new air ducts and sealing up all holes to protect against rodents and SO MUCH MORE. Koala prices were great and super reasonable, the team was professional and courteous, the work was amazing and fast and I just can’t say enough good things about these guys. If you do t hire these them, you’re an idiot. Thank you!!!!

I called several insulation companies before learning about Koala and there is no comparison. Koala called me back within an hour of being contacted, made and kept a free estimate appointment in a short amount of time. Their technician was prompt, polite, the quote was emailed within 24 hours and the service was completed within the promised time. They took precautions to leave the residence as clean as they found it and were very considerate.
