J.N.
We were in this situation last fall and all the garage door companies we called wouldn't give me a quote, besides to say it would be at least $1K. I was so upset, until I found out Lowe's and Home Depot sell garage door systems and have people who install them. It wasw about about $300 for the replacement of our 2-door garage system (not the actual door) and we bought a top of the line quiet system with pass code entry on the outside (great when you leave the house without your control). Whatever you do, shop around!
