911 Insulation did an excellent job with our attic insulation project. They were able to underbid three other companies while providing a very clear, well-written estimate that included helpful photos to explain the process. The finished project was professional, clean, and completed on time as promised. I would definitely use 911 Insulation again when the need arises. I highly recommend them to anyone needing attic insulation.

This company is everything you could ask for when needing a service. Friendly, prompt, and consistent communication. They did a complimentary inspection, and took a video showing me my attic. Honest and reliable, I will highly recommend :)

Fast, efficient and reasonably priced. We're able to finish the project within a week.

Had a great experience with 911 Insulation. Professional consultation with videos, explained various options and answered all questions (thanks Paulo). Consultation Wednesday, job scheduled the following Monday. Pleasant crew showed up on time, worked hard and finished attic insulation in one day. Very respectful of property, covering floor and walls during the process. Sent before/after photos after completion. Quality company, highly recommend.

The workers are not respectful of the property. They left their personal belongings scattered on the driveway, left pieces of plastic from the insulation bags, trampled dirt on the outdoor steps, and scratched the paint off the stairway step. We asked them to come back to fix the step and clean up the mess. They sent workers out today and the workers came to the house and asked to get into the attic. They clearly did not know what they were there for. Loose operation imo.

From the start the company was very easy to work with. Very clear communication. On the day of work, the team was very efficient and were good about keeping areas of the house clean while they were doing their work. One of the one and only times I have had a company actually finish the work prior to what time they said they would! From a cost standpoint - VERY reasonable.

These guys did such a good job re-insulating my attic. My old insulation (the pink stuff in the photos) was old and gross and so thin and energy inefficient. They cleaned up my attic and installed new insulation (the tan stuff in the photo). They even patched up holes and gaps in my HVAC. I wouldn’t hesitate to hire these guys if you have any insulation needs.

Can't say enough about 911 Attic Insulation. It's a true pleasure to work with a company that not only professional and take pride in their work, but they value customer satisfaction. 911 Attic Insulation doesn't hit you with heavy sales pressure. They are comprehensive and informative from consultation through to the completion of installation. They are upfront about all cost and invite you to get multiple quotes to insure they stay competitive. I did at no point feel that I was a bother with my follow up questions/concerns. They were very gracious to answer and follow up with me every step of the way. Thank you 911 Attic Insulation for your professionalism, quality of work and most of all your value in your customer's satisfaction.

Very responsive from the beginning. Workers arrived on time, cleaned up during and after job was done.. all around great service.

Samantha P.Apr 2023

Had recently bought an older home and you guys showed up and completely changed our attic! Thank you for replacing all 17 air ducts and sanitizing while removing all the old insulation. Everyone needs this done every 10-15 years!! Can’t recommend enough.

Wilfred K.Jul 2022

911 attic insulation was great. They removed the old blown insulation, rodent feces, debris, and sanitized the attic. New padded insulation was installed. The crew was highly efficient and informative. The attic and crawlspace was also sealed and rodent-proofed. I would highly recommend.
