We had our garage door opener replaced. We bought it from Sears and then got JK Garage Doors to install it. They were good but told us that we could reuse some of the rail pieces since he said the old parts were made better. We agreed to us back the old pieces but think that the new pieces should have been used. Overall, it works but is still very noisy. We also had the spring replaced as well. I did not like how they left lots of fingermarks and grease/oil stains on the ceiling though.
