Home » How to Maintain Your Windows for Longevity

Windows are more than ways to let in sunshine and spy on your neighbors—they’re a vital part of your home’s structure and aesthetic. But when did you last think about your windows’ durability, longevity, and maintenance beyond wiping away fingerprint smudges?

Neglecting proper maintenance can lead to weatherproof breakage, stuck sashes, rusty tracks, heat-stealing drafts, and costly repairs and replacements. The good news is that regular upkeep can keep your windows looking and functioning great for decades.

The Do’s and Don’t of Window Cleaning

Cleaning windows seems simple, but there’s a right and wrong way.

Do use microfiber cloths or a squeegee for a streak-free shine.
Do mix a simple cleaning solution of vinegar and water for eco-friendly, effective cleaning.
Don’t use paper towels; they leave lint and can create micro scratches on your window panes.
Don’t clean windows on sunny days; the heat causes the cleanser to dry too quickly, leaving streaks.
Don’t (never) use a power washer. It can damage weatherproof seals and force water between the pane and frame.

How Regular Maintenance Prevents Costly Repairs

Preventative care goes a long way toward long-lasting windows. Regular inspections can detect minor issues like cracks, deteriorating seals, and rotting wood before they become significant, expensive problems.

Think of window maintenance like car maintenance. Ignoring an oil change won’t destroy your engine immediately, but the neglect increases over time. A quick monthly check of your windows can save you from dealing with water damage and leaks, foggy panes, or entire window replacements.

Checking for Drafts: Simple Tests for Window Seals

Drafty windows equal higher energy bills and a less comfortable home. Luckily, checking for drafts is simple.

On a breezy day, hold a lit candle or smokey match near the edges of your window—if the flame or smoke flickers or moves erratically, you have an air leak. Another trick is to close one dollar bill in the window. Your seal isn’t tight enough if you can pull it without resistance. Caulking gaps or adding weatherstripping will remedy minor leaks quickly.

Seasonal Care: Preparing Your Windows for Weather Changes

Just like you swap out your clothing for the seasons, your windows need prep, too. Before winter, check for drafts, apply weatherproofing film to single-pane glass, and clean tracks to prevent water condensation and icy buildup. In the springtime, inspect for damage from freezing temperatures and clear debris that may block drainage.
