Windows bring natural light into a home, enhance its appearance, and help preserve indoor comfort year-round. At the same time, homeowners may clean floors, countertops, and other frequently used surfaces, but they often overlook windows until dirt and grime become too hard to ignore.
According to Chad Steger of Clearco Window & Carpet Cleaning and Christian Martinez of State 48 Window Cleaning, keeping windows in good condition comes down to routine attention that prevents buildup, spots potential problems, and extends the life of existing windows.
Window maintenance goes beyond the glass
One of the biggest misconceptions about maintenance is that cleaning the glass is enough. While sparkling panes improve a home’s appearance, several other components need attention to keep everything in working order.
Steger recommends having windows professionally cleaned at least once every three months. This helps prevent dirt, dust, and debris from accumulating and becoming difficult to remove. Regular cleanings also let homeowners check the overall condition of their windows.
Homeowners should also pay attention to screens, frames, sills, and tracks. These areas collect dust, dirt, pollen, and other debris over time. Window tracks are easy to forget – if you can’t see the dirt, it’s not dirty, right? Wrong.
Martinez recommends vacuuming and wiping down tracks every few months to prevent accumulated grit from interfering with window operation. He also stresses keeping weep holes clear. These small drainage openings along the bottom of window frames allow water to escape. When those get clogged, water can back up into the sill or surrounding wall.
When inspecting, check the caulking and weatherstripping, gently rinse screens and inspect them for tears, and make sure sprinklers aren’t repeatedly spraying windows. Hard-water deposits can eventually etch glass, leaving permanent cloudy spots if you don’t address them.
“The biggest mistake homeowners make is focusing only on the glass,” Steger explains. “A proper window cleaning should include removing dirt and debris from all parts of the window.”
Homeowners should also be mindful of the products they use. Abrasive pads and harsh chemicals can damage certain glass surfaces and finishes. Pro tip – especially for Arizonans: clean during the cooler morning hours or in the shade to prevent cleaning solutions from drying too quickly and leaving streaks.
Know when your windows need attention
One of the most important warning signs homeowners should watch for, according to Steger, is moisture or fogging between panes of glass. This is different from condensation that appears on the interior or exterior surface of a window. When moisture becomes trapped between panes, it might mean a window seal needs fixing.
Thankfully, not every window problem means replacement. Drafts around the edges could mean worn weatherstripping or cracked caulking. Windows that stick or are hard to open may have dirty tracks, dry hardware, or debris. Loose locks, damaged screens, and minor surface wear on wood frames can also often be addressed easily – and inexpensively.
Martinez recommends looking for more serious warning signs, such as rotted wood, warped frames, water stains on surrounding drywall or trim, or drafts after replacing weatherstripping and caulking. These issues may indicate a larger problem with the window or its installation. Homeowners should also watch for water pooling on windowsills, which can point to clogged drainage openings or failing exterior caulk.
“Sometimes, though, a good, thorough cleaning is all that’s needed to get things working smoothly again,” Steger says.
Before assuming a window needs replacing, homeowners may want to have it evaluated. Depending on the frame’s condition, replacing only the glass unit may also be an option.
Prepare windows for cooler weather and holiday gatherings
As temperatures begin to cool, windows become an important part of enjoying Arizona’s fall and winter seasons. Homeowners open
doors and windows to let in fresh air, prepare for holiday gatherings, or decorate their homes. Before that happens, both Martinez and Steger recommend thoroughly cleaning windows, inside and out.
“This is especially important around the holidays when you’re entertaining guests and decorating your home,” they say. “Clean windows allow more natural light inside and really make your holiday decorations stand out.”
Fall is also an ideal time to check window tracks, screens, and seals. Martinez recommends checking drafts, replacing worn weatherstripping, and applying fresh caulk where needed. Homeowners can also make sure windows lock properly, since locking them pulls the sash tightly against the seal and helps reduce drafts.
For older or single-pane windows, temporary insulation kits and thermal curtains can provide another layer of protection during colder weather.
A little preparation before decorating can also save time. Cleaning glass, frames, and sills before hanging holiday lights or window decorations makes it easier to reach every surface.
Homeowners should use decorations designed for glass, avoid pinching electrical cords in closed windows, and keep spray snow or window paint away from screens and specialty glass coatings.
Plenty of options let you update without buying brand-new windows. Replacing worn screens, refreshing window treatments, updating locks and handles, or adding decorative or solar window film can make a noticeable difference (check with your HOA first).
Window maintenance is one of those responsibilities that’s easy to put off but worth keeping on a regular schedule.
