J R Door & Window,Inc.


About us

J.R. Door & Window is a family owned and operated business. Jeff Roberts started the business in 1989, after working in the home improvement industry for 13 years selling doors and windows to homeowners and contractors.J.R. Door & Window has become the largest and most respected Milgard certified dealership in the Inland Empire and also serves all of the surrounding communities. At the end of the day, the most important part of the sell is the quality of the installation.Our installers are installation master certified by the American Architectural Manufacture Association as well as Lead Safe certified, which is a requirement with certain homes built before 1978. Our trained professionals have a financial incentive to do a good job and make the customer happy because a good portion of their pay depends on the result of a customer satisfaction survey. This is how we can control the quality of the installation, and for that reason we can provide a written lifetime installation warranty.

Rated 5 out of 5 by from Professional team The folks at JR Door and Window are always a pleasure to deal with. We have used JR Door on three separate occasions. Each time they have responded timely, communicated completely and, showed up on time to do the job. The workmanship is top notch. Kudos to Daniel the door man and Steve in sales. These guys make it easy to say yes to JR Door for my next job.

Rated 5 out of 5 by from I was so satisfied I will use JR Door and Windows for my next project too JR Door and Windows planned, procured and executed my non-standard home project to my fullest satisfaction. They stayed within budget and met schedule constraints. Their "on-site" team was polite, knowledgeable and kept our home clean. The final product met all my expectations. I am now planning more work with them.

Rated 5 out of 5 by from Professional installation of beautiful windows. My new energy saving windows keep it darker inside the house and much cooler; sealing the windows so that heat can not enter through the window area (19 windows) during the summer or exit during the winter. The installation people were extremely professional and able to put the windows in so that the windows have no escape of air or heat between cracks which no longer exist. When the temperature is over 90 degrees outside the air conditioner doesn't have to work 8-10 hours per day, but stays below 80 degrees until 5 or 8 pm in the evening. The air conditioner has less than 30 minutes to work per day now that I will save 20-30 % on electricity.
