Bi fold doors
The doors were measured and a very reasonable price was quoted for bi folds with internal blinds. We went ahead with the order and they were delivered and fitted yesterday as booked. The lads that came to fit them turned up on time, were very friendly did a great job. We will definitely be using the company again and have already had them measure up for a new window.
Great company and no issues at all
