"The entire experience was great! From J.B. giving the full rundown and report on the process to Joe and Marty performing the work. Everyone was extraordinary and went above and beyond to make us feel valued. Too early to really tell the difference the new attic insulation will make but seeing the final product first hand, I'm impressed!"

"Advanced Attic Insulation did a great job with our attic insulation upgrade and soffit vent installation. The crew was professional, friendly, and explained the process clearly from start to finish. They arrived on time, kept the work area clean, and completed the project efficiently. They installed new insulation and improved the exterior with soffit vents, which should help with airflow, energy efficiency, and overall attic performance. The workmanship looked clean and well done, and they answered all of my questions throughout the job. Overall, I am very satisfied with the experience and would recommend Advanced Attic Insulation to anyone looking for attic insulation or ventilation improvements."

"Chris did some tedious insulation work for me in my 140 year old carriage house. He showed up as promised, got the job done and left the place cleaner than when he arrived. His pricing was reasonable. I would highly recommend CJM for any insulation needs!"

Insulation FAQs, answered by experts

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.
