Hired on Thumbtack

The job was installing new vents, replacing duct work and resealing areas where rust had taken hold. I used to feel a breeze under my house because of how many open areas there were in my duct work. No more breeze. Working with Day and Knight was straightforward and easy. They came out quick, we talked about the job and we agreed on a price. They came out and did the work exactly as planned.
