Our Story

R12 Window Cleaning was established in 2012
My partner and I have a real desire to bring customers satisfaction back to the level it should be. We are not in this for any other reason then to be known as the go to guys. Our goal is keeping customers happy and willing to refer us to friends and family.

What We Do

Window Cleaning

At R12 Window Cleaning, we specialize in cleaning windows on everything from residential homes to large commercial buildings. We clean both inside and out, tracks and screens for excellent results. We also handle problem windows that require scraping to remove paint, stucco, hard water, and other tough build up. It is our commitment to use only the best quality cleaning products and cleaning techniques so that is why we have chosen to use squeegees and other specialized tools, including de ionized water ( a form of purified water ) as part of our cleaning tool-kit. With R12 you can be assured a streak free shine without any residue that can be left behind from the traditional window cleaning method of paper towels or spray chemicals. Call R12 Window Cleaning at 408.372.7712 for a free estimate (If your windows require extra attention please let us know during your free estimate.)

Gutter Cleaning

R12 Complete Gutter Cleaning Service starts with blowing off roof debris to help prevent further debris build up in your gutters. We then continue and remove all of the debris currently in your gutter system using specialized hand tools. Once the debris are removed from the gutter system, we finalize our cleaning by flushing the gutters with water to remove any remaining sediment and to verify that the gutters and down spouts are flowing at 100% efficiency. Any areas that are not flowing correctly will be inspected and we will remove any missed/hidden debris or build up. R12 guarantees customer satisfaction or we will come back and clean your gutters again.

Bird Abatement

R12 provides bird abatement.

Pressure Washing

R12 Pressure Washing Service offers deep cleaning of your designated surface(s) to remove all sorts of grime build-up or to strip down a surface. From a mild low pressure cleaning for exterior walls to a high pressure surface stripping to prep for a paint job, R12 has the right nozzles, attachments, and detergents to get the job done right using our interior and exterior pressure-washing equipment.

The R12 team was quick to respond to my inquiries and was out to clean my gutters and windows (inside & out) within 3 days.

They were flexible, efficient and clean. In addition, they were very tolerant of my kittens that followed them from window to window.

I was very pleased with the results and have already scheduled them to return after the new year.
Jennifer Miller
Just had my windows and gutters cleaned by Brad and Shane of R12 - LOOOOONGG overdue and it looks awesome. I could sing the Johnny Nash song "I Can See Clearly Now (the rain is gone)"!

Very nice and super fast and efficient - even wore booties in the house and were careful moving stuff.

Definitely will use them again!
