Window Maintenance

Condition: Window frames, sills and sashes should be monitored because the interior condition and hardware of windows change over time. Frame materials can include plastic, aluminum, steel, wood, plastic-clad wood, and metal-clad (steel or aluminum) wood. Window types include double-hung, single-hung, casement, horizontal sliding, projected out or awning, projected in, and fixed.
​In addition to these, there are jalousies, which are glass louvers on an aluminum or steel frame.
At older sashes, the glazing compound or putty around the glass panels should be monitored carefully, since this is a vulnerable part of the window and its repair is time-consuming. Check the panels in steel or aluminum sashes for signs of deterioration, such as hardened sealant. Check metal sashes for weep holes that have been blocked by paint, sealant or dirt. Weep holes are usually easy to clean. Storm windows and doors should be monitored for operation, weathertightness, overall condition, and fit.
Weather stripping: Window and door weather stripping is generally one of three types: metal; foam plastic; or plastic stripping. Each type should have a good fit. Check the metal for dents, bends and straightness. Check foam plastic for resiliency, and plastic stripping for brittleness and cracks. Make sure the weather stripping is securely held in place.
