What Our Customers are Saying

  • As a contractor, I’ve been using Johnston Millwork as a source for quality windows, doors and moldings for more than 7 years. Whether it’s a small, straightforward order or a large quantity of custom windows and doors, I’ve found their knowledge and resources to be invaluable. They also have the ability to produce customized windows and doors in-house, which can have its benefits. They’re up front about delivery dates, which is critical for keeping my projects on schedule. If there are issues, they resolve them promptly and professionally.

    Steve B. Contractor, Menlo Park
  • I’ve been doing business with these guys for over 15 years and they have always been thoroughly professional and very accommodating, rectifying mistakes quickly regardless of where the fault was made and they have a great selection of products…very handy! Wonderful people, great place.
    Henry A. Contractor, San Carlos
  • JMI was on time and saw that our existing front door frame needed modification and they came up with an excellent suggestion. They were so clever I had them look at another problem and they suggested an alternate and less expensive solution. So we are hiring them to do that, too! I have found them to be honest and trustworthy and cared more about my needs that their bottom line!
