John's Window Capping specializes in restoring and capping wood casement windows. I realized that cladding casement windows would be my specialty when I started cladding in 1978. I have been restoring wood casement windows for over 30 years and I still enjoy the process and challenges as much now as I did when I started.

When aluminum cladding is installed on wood casement windows it vastly extends their useful life expectancy. When properly maintained a casement window can easily combine the beauty of wood, low maintenance and very high energy efficiency. If you enjoy the qualities inherent in your wood casement windows but no longer wish to spend the time, money and effort required to maintain them call John at (403) 370-4802 to arrange for an estimate. The suitability of your windows for cladding will be determined and your job can be scheduled at that time if you find the cost acceptable. The vast majority of the estimates done by "John's Window Capping" result in jobs for us. This is due to our high quality workmanship and the competitive pricing we offer. We understand the market and will present you with a price that will allow you to enjoy the benefits of low maintenance wood casement windows.

Wood windows have very high insulating properties and have the added advantage of being attractive. Wood windows can be painted or stained on the interior surfaces and clad or painted on the exterior surfaces. This versatility and energy-efficiency are two reasons that homeowners are attracted to wood windows. A wood casement window that is in good operating condition can produce an excellent thermal barrier. Cladding to the exterior surfaces eliminates maintenance and make this a great choice for the discriminating homeowner.

  • I recently used John's Window Capping to refinish all the windows in my 35 year old house and am pleased to recommend John highly and without reservation. The work was done with pride and care. They were extremely clean and very respectful of my home. My windows look new and modern and the outcome is wonderful. I highly recommend this company. CM Kidd


  • Thanks again for re-vamping those windows for us, they look so much better and it was a relief to have that ongoing task off my list. We also really appreciate the work ethic and splendid attitude you both show, makes a big difference in a world where the personal aspect has slipped away. I have run my own business for over 25 years, I try to always treat my clients the way you treated us. Thanks again Laura


  • Thank you for the wonderful capping and window repair work you have done. It looks great and willl maintain the life of the windows for a long long time. We really appreciate your ability to patiently explain the process and the care you took during the installation. It was a pleasure working with you and the boys from start to completion.
