Had R20 in our attic and invited a couple companies out to give a quote to bring the R-value up to Current standards.
Scott at Tennant Insulation was the only contractor who showed real professionalism and knowledge of the quotes I recieved. Scott was not pushy at all unlike another contractor I dealt with.
It was recommended that I increase my Insulation to R60.
I also had my skylight tunnel spray-foamed to increase its R-value which should seal off any leakage. Being COVUD times the spray foam wasn't available for Scott so he brought in a contractor who had a supply of the product to get the job done in a timely manner.
Cost without the skylight Insulation was less than other quotes. Skylight added about 1500 to the total.
We used by Scott's recommendation a synthetic material which has a large percentage of it as recycled material. And it settles much less than cellulose products.
All on all, I'm very satisfied with the detail of work that was done.
