Hired on Thumbtack
Green attic came out and took a look at my mudroom letting me know adding insulation probably would not help too much. They said I would be better off adding a potential duct with vent. I appreciate the honestly and no high pressure sales tactics.

Hired on Thumbtack
While we determined that I may need to seek additional confirmation as to the possible issue, the person that came out was very professional and gave, what I believe, to be good advice to check on some other things before possibly incurring what could be a large expense.

Green Attic weathered my home. Jaime and Carmelo were very nice and courteous. They worked really hard to complete my job. They went above and beyond to take care of everything! I would recommend them if you need weatherization of your home. They also gave me a reasonable new roofing quote. Will be next on my list later.

I bought a 2flat a couple years ago, not aware how bad the initial build had left the attic/AC in. Green Attic's estimate and detail of steps to rehab was the most clear and detailed of what I reviewed. The installation crew were professional, thorough, met every detail spelled out on the estimate within budget and cleaned up so well you'd have no idea anyone had been in the hallway in the last week.I really appreciate the effort and turnaround. I highly recommend giving Green Attic a call and getting an estimate.

Had proper attic ventilation installed into our attic and blown in insulation added to our attic. Quoting process was simple and hassle-free. Quote was extremely competitive in the market. Personally, I liked that they used green-based materials. Every part of work was highlighted and explained well in quote (you can call if you have questions). Omar and his team arrived on time and were able to complete the work quickly (2 days scheduled, and was able to complete in single day). Everyone in the team was respectful and provided good communication and zero issues during the job. Would recommend them to everyone and will hire them again if more work is needed in the future.
