“We used Attic Star to do our insulation and rodent proofing/exclusion work. Zabi, our project manager was absolutely amazing. Very professional, courteous, and very helpful. He checked everything multiple times, took pictures and confirmed the work was done 100%. He showed me in the attic exactly what was done. They were very competitively priced too compared to others. Would recommend working with them.”

Blown-in insulation is one of the most effective ways to improve energy efficiency and reduce indoor temperature fluctuations. Perfect for attics, walls, and tight spaces, this insulation is applied using specialized equipment that fills gaps and voids for complete coverage.
At Attic Star, we use top-quality cellulose or fiberglass materials that are fire-resistant, mold-resistant, and eco-friendly. Our expert team ensures quick and clean installation with minimal disruption, delivering an insulation solution that keeps your home cozy in the winter and cool in the summer—all while lowering your energy usage.

“We had a disgusting situation. Not only did our newly purchased house have rats in our attic and walls, our attic insulation was covered in rat droppings. Our attic is also a very tight space with really low clearance. Zabi was our project manager and he provided excellent service and made sure the job was done well. We are now rat free and the old ratty, blown-in insulation has been replaced with nice R38 rolls. I would definitely recommend Attic Star.”

“Several years since becoming a customer and over a handful of visits, I continue to be impressed with the quality of the service and professionalism. They respond quickly to emails. They show up when they promise. Techs are courteous and thorough. They honor their warranty. Really a pleasure to work with.”

“These guys are great! They go above and beyond to get the job done. They did a great job of the removing the rodent droppings and insulation, replacing the insulation, and restricting rodent access in the future. By far the nicest thing was that they helped me get down all the stuff in the attic that my mother left when she passed. And then they hauled all the boxes and junk away too at no extra charge. Thanks guys!!!”

“My wife and I are seniors and the Attic Star crew has been so respectful and accommodating. From the initial contact, Attic Star has been prompt with messages and replies, and punctual, showing up early each morning, and putting in a full day’s hard work. Jay is the general manager of this project, and he is a pro, friendly, and somebody we feel very comfortable with what for us is a big project. Prices are extremely fair with no hidden charges or trying to upsell anything. A special thanks to the crew of Attic Star for a very hard job of working in the attic and crawl space.”

“We moved into our first house and quickly discovered that something was partying in the walls/in the attic every few nights. Attic Star came out, diagnosed our rat problem, reported how ineffective our insulation was, and quoted a price much lower than that of a similar competitor. One standout part of their service is that, for all 3 visits, they called ahead of time and showed up promptly as discussed, making it easy to accommodate the visits in the midst of work meetings and other activities. We are very happy with Attic Star’s service and will definitely be calling them again for future projects like replacing old ducts and installing fans to cool the attic.”
