I couldn't be more thrilled with the service from this insulation company! We brought them in to clean our attic, and they did an outstanding job. Our attic looks absolutely spotless and is all set for the new insulation installation. The team was super professional, efficient, and took great care with our belongings.

Excellent work by this insulation company! We needed a significant upgrade in our home, and they made it possible. They started with a thorough attic cleaning and old insulation removal, then installed a new attic insulation replacement and a radiant barrier. The change in our home's temperature and energy bills has been drastic. Furthermore, their team was very professional in performing the rodent proofing, giving us complete peace of mind. Highly recommended for their efficiency and results!

I'd been having some problems with rodents and called them on the recommendation of a friend, and the work Tom and Daniel did was exceptional. They're definitely a great team! Thank you

The radiant barrier that Attic Star put in has truly changed the game for my home’s temperature. It’s so much cooler during those hot summer days. The crew was really knowledgeable and did an amazing job. I couldn’t be more satisfied with the outcome

Upstairs air quality was restored after mold removal in the crawl space. No changes in humidity were detected by Daniel. The stench of mildew vanished.

Attic Star truly delivered an outstanding experience from beginning to end. Their team was not only professional but also incredibly efficient, making the whole insulation removal process feel effortless. They kept me in the loop at every stage, so I always knew what to expect. My attic feels so much better now, and I can already see a positive change in my energy bills. I wholeheartedly recommend Attic Star for their exceptional service and expertise in attic solutions

Jose did a great job with his inspection and remediation in our crawl space. He was very thorough, showed me the problem, and fixed it. I have had a good experience with Attic Star

Loved my experience with Attic Star. Someone came out to do a free inspection and after comparing prices I was able to schedule work promptly. Ricky was communicative, on time, and professional. He sent me photos of the before and after and left the place clean. He was also flexible and creative when I said that I’d need to leave access to the upstairs bedroom available while also keeping things safe while removing insulation. Great work!

I never imagined having my attic so clean, in the most cozy way, and with insulation that's just wow... The team was excellent throughout the entire job. They were organized and made sure to clean up everything in their path

Crawl space humidity stabilized after remediation and ventilation adjustments. Daniel verified readings during follow-up. Indoor air feels healthier.

Attic Star really knocked it out of the park with our attic insulation. We've seen a noticeable boost in our home's energy efficiency and overall comfort. Their crew was quick, knowledgeable, and the whole process went off without a hitch from beginning to end. Five stars all the way

We knew we needed expert aid when we found out that mold was growing behind the walls. Tom took care of the mold removal carefully, explained the safety steps thoroughly, and made sure the area felt clean and habitable again.

Attic Start offers incredible service. The team arrived on time and everything was extremely fast. They did a fantastic job. Before contacting them, my attic was a dusty and dirty space. Now it looks like new, and I feel more comfortable in my home. I highly recommend them!

HVAC airflow was weak even after replacing filters. Old duct lines showed contamination and partial collapse in some areas. Air ducts replacement solved the issue, and Tomer reviewed system pressure readings before leaving. Performance is noticeably stronger.

Beyond impressed with their work! The technicians were courteous and hard-working, treating our home like their own. Our energy usage has dropped significantly since the new insulation was installed. Five stars

Needed an emergency cleanup and insulation replacement. They responded quickly and delivered outstanding quality work. They genuinely cared about fixing our issue. It’s comforting to know the job was done right

After years of temperature imbalance, insulation replacement made an immediate difference. Tom kept the process simple and transparent. The house now holds heat and cool air much better.
