IMPORTANT UPDATE: ROI is no longer able to install or service windows and doors

R.O.I. Home Improvements, Inc.  is now specializing in Screen Room systems, and product only for new construction.  We are no longer able to offer installation of windows and doors.  If you purchased windows or doors from us in the past, you manufacturer warranty is still in full force.  For service, we have always acted as an intermediary for the manufacturers.  We contacted the manufacturer, filled out the warranty service request on your behalf, and basically monitored the service to make sure they stayed on task.  The manufacturer furnished the parts at no cost for all warranty failures, and dispatched their own employees to complete the labor portion.  However, now you will need to reach out directly to the manufacturer.  In my experience, and feedback from customers, the service personnel are very knowledgeable, professional, and dedicated.  I have no doubt they will continue to take good care of you moving forward.

For Milgard products (which is now MI Windows) Call 800-645-4273 or go to and at the bottom of the page there is quick help: request service.  You will fill out an online form there.

Amerimax windows (Cascade Windows)  800-442-8544 or go to and fill out a warranty request there.

Simonton: 1-800-745-6686 or go to

When we sold you the windows, we probably told you that the reason we went with these manufacturers were their exceptional product, reasonable pricing, beauty of the product, and that God Forbid, something happen to us, the lifetime warranty was with the manufacturer so you are covered if we are ever not able to.  Well, we were the last people to ever expect not being able to service you for many many years.  We thank you from the bottom of our hearts for trusting us with your homes, and I am so very sorry for the extra steps for you moving forward.  I will always try to help if I am able, and if you run into something you cannot resolve and need my help, I will do my very best to help in any way I can.

We have always had the most amazing, gracious, genuinely nice customers, and I thank God for you all and hope He continues to bless each and every one of you with happiness and good health.  In the end, that’s all that matters.
