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.
