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 Excellent Business Ethics J.R. came to my house and did complete workup on my quote for windows & doors. Excellent customer service and knew exactly how to answer all my questions. I signed the contract we agreed on and have to say it was a real please doing business with him. F.Y.I. Previous to this , I had several other companies @ quotes. None of them knew the business and product like J.R Door & Window,Inc. One of them was totally un-truthful in their contract, I told the rep. that came out and cancelled all further communication with them.
