I knew for a while that I needed insulation blown into my attic (there really wasnt much there); finally decided to research, and received a few quotes.
After chatting with Richard from Fanattics, , and then after meeting with other companies, I decided to go with Fanattics because they offered better service options than the other quotes, more bang for your buck:
get a solar powered roof vent/fan installed at no additional cost
free roof inspection/light fixes if necessary
other little things that made the cost worth it.
I was especially happy with the roof inspection, because, living in a semi, I had a feeling that my neighbours roof was nit in great shape, which was a concern for me.
Richard identified a few problems and fixed the roofing cap that was improperly installed by the roofing company my neighbour used, and then he highlighted some other areas (with pictures) on my neighbours roof that needed repairs.
All that to say, I would definitely recommend Fanattics, they are 100% worth it.
