We needed to add insulation to bring it up to the level of R60. Wojtek who came to give us a free quote pointed out that our pot lights were not appropriate for the insulated ceilings as they can cause fire. That was really very thoughtful. After we replaced the pot lights, we scheduled the job. It was done very efficiently with no mess. They also did an insulation of the hatch. Everybody was very polite and it was very nice to have business with them. Highly recommended.
