Attic Bros did a great job in my attic today. They were professional and friendly. I had a bid for $800 cheaper from another company but decided to go with Attic Bros because of the good vibe from Michael when he came out to give me an estimate. When they were finished, their boss stopped by to make sure everything was done thoroughly and correctly. A-1

I recently used Attic Bros for an inspection and had a great experience. Their website was easy to navigate, and I was able to set up an appointment quickly, with the inspection scheduled for the very next day. Najim, the inspector, was professional, honest, and thorough. He called ahead to confirm his arrival time and showed up on schedule, fully prepared for the inspection. Najim checked both my attic and crawl space, addressing all of my concerns. I highly recommend Attic Bros and appreciate the excellent service from Najim and the entire team. Thank you, Najim and Attic Bros!

This was our first time using the company after being recommended by a co worker. The guys did an awesome job keeping our home clean while hauling away the old insulation. The workers were friendly and professional. We like how they kept us updated by taking photos of the progress. Joey and Pedro came back the next day to finish and did a great job.

I had the attic re-insulated crawl space cleaned and attic fans installed. Very professional, thorough and punctual from the initial visit estimate to job completion. The estimate was performed by Michael and another rep he was training. They were very thorough and detailed with the work that needed to be completed, and provided the quote at the end of the visit and made sure all my questions were answered. On the day the job started, Jordan was the project manager with a crew of two guys . They taped the access area with plastic at the start of the job and cleaned up when they were done and Jordan kept updated through out the process. Later that evening, I noticed my kitchen and dining lights weren’t turning on , Jordan came back the next day to fix the issue.

Just used Attic Bros to replace our attic insulation. Michael was very thorough during the initial appt, and Vic & his crew did great work. Every step of the way, from scheduling the bid appt to completing the work and sending us before & after photos along with the invoice, was easy with them. We look forward to seeing if our heating & cooling energy decreases. I highly recommend AB.
