We decided to participate in the government home upgrade rebate program and contacted Kovar for a quote additional insulation and air sealing in our attic. Kovar was very responsive and we had a visit scheduled within an hour of reaching out. The quote provided was reasonable and they were able to do the job within a few weeks.
Once completed, a secondary energy assessment from an independent company confirmed the job had been completed very well and the blower door test confirmed the air sealing completed had indeed greatly reduced air infiltration. The upstairs feels less drafty and the furnace runs less often and overall were more comfortable.
I would not hesitate to work Kovar again.
