They were polite, clean and did not leave a mess. We had a trailer there as we were looking after the old doors and everything is piled so neatly on the trailer we do not have to rearrange anything. Little pieces were put together in a box. No screws or pieces of anything were left on the floor. Garage was left spotless they must have swept the floor when they were done. I would highly recomend Cliff's!

Very efficient, answered all questions, cleaned up nicely.
The only issue was the long delay to install after initial quote - just the market unavailability of the construction materials and not the fault of this company. Still have a 5 star rating.
