Sindor installed trickle vents into the heavy wooden front door of the house as well as into two upvc French doors to my garden. I found Sindor and his service to be professional, able and thoughtful (clearing up afterwards). I would happily recommend him for this type of work.Verified reviewerJob location: NW10- AAdam S
