If you are wanting to repair your garage door and are not too sure how to go about it then you should speak to Richard at www.garagedoor-spares.com
After I had had a quote for a new door for £450.00, I was determined that I could replace the cables and the roller spindles myself, I spoke to Richard (the owner) he gave me the confidence and also supplied the fitting instructions to help me complete the repair in less than 1 hour.
I have recommended the www.garagedoor-spares.com to my brother and father who have also used the website to get a old door working lioke new!
