I recently had The Exterior Zone come out and give me a quote (and perform work) for more attic insulation. Overall 5/5 recommendation for them!
During the process their operations manager Chris was professional, friendly, not pushy or trying to upsell, and he explained their whole process from start to finish. We went through the attic together and I explained what I wanted done and he pointed out a few issues currently happening in my attic. He explained the process he would like to take to correct those issues and answered all my questions. Before our project we had ventilation issues with our soffit baffles having fallen over and were in fact blocking most of the air flow rather then directing it. We had a few other minor issues all of which he pointed out and his crew ultimately fixed.
We went from R11 rolled insulation to adding blown in material to take the attic to an R60 value. Definitely can already tell there is an increase in home comfort and a reduction in how often my HVAC system is running. Ultimately though my biggest concern was that ventilation and humidity issue and I am confident that will not longer be a problem. Even if it is, the exterior zone guarantees their craftsmanship and work.
I got to say from the beginning of the process to the very end I was pleasantly surprised how happy I'd be with them. Everything was painless, didn't feel pressured on any of it, the work itself was done correctly, and I'm very happy.
As far as price goes I didn't even bother getting other quotes. I normally like to get at least 2 quotes sometimes 3. But having previous recent experience with attic insulation I knew roundabout what my price should be. The price I paid for this project was almost exactly what I was hoping for, even considering the extra work required in my attic beyond simply tossing in more insulation.
I will definitely be considering Exterior Zone for more future projects...
