When it comes to window repair, a lot of homeowners consider themselves up-to-date with their household’s health. While they may take extra care in protecting the home front, they may be overlooking important window problems. Windows can be damaged instantly, but they can also accrue damage over time. To avoid costly window replacement, protect your installation and maintain a safe household, check out the lesser-known window damages below.

Siding Degradation

While your window’s siding is durable—incredibly durable, in fact—it can still wear down over time. Mostly, siding is damaged by water. Even if your windows are shut, water can still get inside. It can damage a window’s siding. Over time, the siding can corrode, allowing more water in. In the vicious cycle, a window’s edges can be worn down.

To target sliding damage, pay attention to any wet spots near your windows following a storm. If water is dripping or sliding down your window’s frame, you may need to repair degraded sliding.

Loose Weatherstripping

Weatherstripping, too, is often overlooked. It can come loose over time, however, and needs to be looked at annually. Windows are rated with individual U-values. Unlike insulation’s R-value, a lower number depicts better insulation.

This insulation is maintained by weatherstripping—which can come loose near the window’s sash. If your window’s stripping is peeling, or if it’s missing chunks, it’ll need to be replaced. Fortunately, it’s easy to find out if your window’s stripping is coming loose. Check for intense drafts, bending sides and increased condensation. A window’s failure to insulate a home is evidence of damage—and you should take great care with weatherstripping and siding replacement to protect your home.


Sometimes, humidity and water can cultivate mold growth near a window. In fact, a lot of homeowners face the problem of moisture penetration in the incarnation of mold damages. If your window isn’t insulated enough—or if bad weather has introduced a lot of humidity, moisture accumulation near your window’s bottom can degrade your window area’s protection.

If you’ve spotted mold, you should check your window’s exterior seals. Either an improper window installation or simple aging can result in mold growth, and a lot of homeowners face interior water penetration caused by poorly functioning window seals. If you ever experience overflowing water, you should check for mold immediately. It doesn’t take long for mold to grow, and the shortest presence of water is enough to promote growth.

You should examine your windows, entry doors and patio doors every year. Of course, check out any glass for abrasions and scrapes—but don’t neglect the seals and siding. All too often, homeowners prioritize a window’s face, overlooking defects and damages. Again, even a small leakage can result in bank-breaking repair jobs—so don’t ignore any interior moisture.
