Green Attic does really great work. An estimator came out ti my home within a day of my making contact. The estimate came within an hour or so of the estimator's visit. The work started a few days after that. Green Attic's crew of Walter, Virgilio and Ricardo spent three days at my house removing insulation in two separate attics, sealing the attics, and then reinsulating them. They also insulated two hard to reach soffits. The crew was clean, friendly and very respectful. I'd highly recommend Green Attic and use them anytime. Just a great experience for a difficult job and potentially messy job.
Green Attic's reply
Hi Craig, thank you for the ⭐⭐⭐⭐⭐ review! 😊🏠
We’re very glad to hear you had such a positive experience with Green Attic Insulation from the initial estimate through the completion of the work. Quick scheduling and clear estimates are important to us, so it’s great to know that part of the process worked smoothly for you.
A big thank you for recognizing Walter, Virgilio, and Ricardo. Removing old insulation, air sealing the attic, and installing new attic insulation, especially in multiple attics and tight soffit spaces, can be challenging work. We’re glad the team kept the job clean, professional, and respectful throughout the project. 🧹🛠️
We truly appreciate your recommendation and your trust in our team. If you ever need help again with attic insulation, ventilation, or energy efficiency improvements, we’ll be happy to assist. 🔥❄️👍

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 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.

This winter broke me. I contacted green attic to have my home insulated with blown insulation. It was a big job. But one where we immediately recognized benefit.My house was built in 1917 and renovated by a flipper 14 years ago. In the 14 years we have lived here my home has never been over 65 degrees in the winter or below 78 in the summer.After day 1, for the first time in a winter month my house reached the temperature I set on my thermostat. After day 2 the whole house was comfortable and able to reach any temp we set it to. My thermostats have to relearn.The job is incredibly messy - during day 1 I was very concerned about my family being able to sleep in the home. That fear was misplaced. Each day the entire crew cleaned up after themselves flawlessly. It was truly amazing to see the care they took getting us comfortable.The whole job took 5 days. The entire experience was thorough from the consultation with Frank. The project management with Marco was exceptional. The drywall finisher Selvin stayed on the final day until every detail was was perfect.I used to dread my peoples gas bill in the winter and comed bill in the summer. I cant wait to see it now.Thank you!

Hi Dan, thank you for sharing such a thoughtful review. We truly appreciate it. 😊🏠
Homes built in the early 1900s often struggle with insulation and air leakage, so it’s great to hear your blown-in insulation project made an immediate difference. Being able to finally reach the temperature set on your thermostat , and keep the whole house comfortable is exactly what proper attic and wall insulation should accomplish. 🔥❄️
We also appreciate you mentioning the team’s work throughout the project. Frank for the consultation, Marco for project coordination, and Selvin for finishing the drywall details all take pride in doing the job carefully and thoroughly. Large insulation projects can be messy by nature, so we’re glad the crew’s cleanup each day helped keep your home livable and comfortable for your family. 🧹
Thank you again for trusting Green Attic Insulation with your 1917 home. Improving comfort while helping reduce heating and cooling costs is exactly what we aim for. We’re grateful for the opportunity to help. 😊👍
