The Smart Homeowner’s Guide to Maintaining Your Windows in Raleigh, NC

Windows add beauty to your home—but they’re also structural, making regular maintenance a must.

If you’re committed to protecting your investment and extending the life of your windows—especially in a place like Raleigh, NC, where we see everything from high humidity to the occasional winter freeze—regular maintenance is essential.

Here are the most important steps every Raleigh-area homeowner should take to keep their windows operating efficiently and looking their best.

1. Clean Glass Surfaces Regularly and Thoroughly

While cleaning may seem like a cosmetic chore, the buildup of pollen, rain residue, and pollutants—especially common in the Raleigh area—can gradually degrade the surface of the glass. Using a gentle, streak-free cleaner along with a microfiber cloth helps maintain both clarity and longevity.

Avoid cleaning in direct sunlight, which can cause the cleaner to dry too quickly and leave streaks. For best results, clean both interior and exterior surfaces every few months

Pro Tip: Opting for tilt-wash windows simplifies exterior cleaning on upper levels by eliminating the need for ladders or specialized tools.

2. Inspect and Replace Caulking and Weatherstripping

The seal around your windows plays a critical role in keeping outside air and moisture from getting in. In a climate like Raleigh’s, where summer heat and heavy rains are common, damaged caulking or worn-out weatherstripping can lead to energy loss and water intrusion.

Inspect the seals around your windows each spring and fall, checking for cracks, peeling, or gaps. If you notice any issues, reapply a high-quality exterior caulk or replace the weatherstripping to restore a proper seal—this simple maintenance helps keep your home comfortable and reduces strain on your HVAC system.

3. Open Your Windows Regularly to Prevent Sticking

It might not cross your mind often, but opening and closing your windows regularly helps ensure everything continues to function properly. If windows are closed for long periods, the tracks can accumulate dust, pollen and moisture.

Gently clean the tracks with a vacuum or soft brush, and apply a silicone-based lubricant to the moving parts. Avoid oil-based lubricants, which tend to attract more dirt and grime

4. Look for Fogging or Moisture Between Panes

Seeing condensation between the panes of a double- or triple-pane window is more than a nuisance. It usually means the window’s insulating seal has failed. This reduces thermal performance and may lead to further issues such as mold growth or energy inefficiency.

Because Raleigh’s humidity levels can be high for much of the year, this is a fairly common issue. If you notice moisture between the panes of your window glass, it could be a sign of seal failure. A professional glazier can evaluate the problem  and determine whether the window can be repaired. In many cases, if the frame is still in good condition, a full window replacement isn’t necessary.

5. Inspect Frames Based on Their Material Type

Your window frame material—whether wood, vinyl, fiberglass, or aluminum—dictates the type of maintenance needed. For instance, wood frames should be painted or sealed every few years to avoid rot. Vinyl frames require less maintenance but may warp with prolonged heat exposure. Aluminum frames can oxidize over time if left untreated. 

As part of your seasonal home checklist, take a moment to inspect all window frames. Look for signs of rot, soft spots, cracks, or discoloration. Catching these issues early prevents more serious and expensive repairs later.

6. Address Concerns Promptly

Every home seems to have that one “problem window”—it leaks when it rains, won’t open easily, or it always seems colder near it in the winter. It’s tempting to put off dealing with it, but even minor issues can lead to significant damage.

In some cases, the issue isn’t wear and tear—it’s poor installation. If you suspect your windows weren’t installed properly, a professional can perform a water test to help identify the issue. Improper installation is more common than many homeowners realize, and catching it early can prevent costly moisture damage.

Final Thoughts: Your Windows Deserve to be Maintained

Windows are one of the few elements of your home that impact curb appeal, comfort, energy efficiency, and security all at once. Maintaining them is simple with consistent care and prompt attention to any signs of wear or damage.
