We’ve just had a Solidor composite door and surround fitted and it’s excellent . Well built, feels really solid and improved the insulation no end . I used a local (to me ) companionships so cant recommend one local to you . Happy to pass on their details .
Had s new garage fitted a couple of years back and the car meant were from Derbyshire . It was one of the concrete panel garages which can be built in half a day . Again, really impressed with them but not sure if they just did the garage doors .
