Its a local company here in Middlesbrough. We've had good recommendations from friends about them, and to be fair the quality of the install has been good, its just the little things like cleanliness and care that differentiates average from very good, and so far they've just been average.

Don't really want to name them as it would be unfair for me to slate them by name before the job is fully completed and I get a satisfactory resolution to the above.
