How do I specify the size of the replacement door I require?

The dimensions quoted as the opening size of an up-and-over garage door are always expressed as WIDTH x HEIGHT and refer to the opening within a suitable timber frame or within the factory fitted steel frame, and NOT to the actual size of the door. We can quickly establish this on your behalf if you ask for a free on-site survey and quotation – from this, we can recommend the best options for your situation.
