This company provides good service for garage door installation. Thought of installing it ourself, but instead decided on using professional service. We did not go to R & R directly, instead, was referred by Lowe's after purchasing our garage doors. They came out within the same week and installed the doors and sliding frames. We just paid the basic installation fee, however the only thing was that the company required us to buy another piece in additional for them to install the garages, because of the change in doors or height?!?!? Overall, the installation guys were helpful and answered our questions. You can also go to them directly for services, just located in Rancho Cucamonga.
