Highly recommend Rennova
Super company to deal with from start to finish. Had a ton of questions, all answered so came up with a door model that suited my needs and pocket.
The guys who fitted the door were so efficient - didn't even stop for a cuppa - and did a fab job. Left the place spotless, put up a post box for me and took the old door, sides and overhead window frames and glass, a pleasant surprise i wasn't expecting.
Would highly recommend Rennova and LOVE my new door!
