Essential Window Maintenance Tips for Longevity

One of the greatest benefits of modern UPVC windows is their low maintenance requirements compared to traditional timber windows. However, "low maintenance" doesn't mean "no maintenance." With regular care and attention, your windows can maintain their appearance, functionality, and energy efficiency for decades. In this comprehensive guide, we'll share expert maintenance tips from our technicians at Cotonsladzo to help you maximize the lifespan and performance of your windows.

Regular Cleaning: The Foundation of Window Maintenance

How Often Should You Clean Your Windows?

The frequency of window cleaning depends on your local environment:

• Urban Areas: Every 3-4 months due to higher pollution levels
• Coastal Areas: Every 2-3 months due to salt spray
• Rural Areas: Every 6 months may be sufficient

However, these are just guidelines. If you notice a buildup of dirt, grime, or water spots, it's time for a clean regardless of the schedule.

The Correct Cleaning Method for UPVC Frames

Proper cleaning technique prevents damage and preserves the appearance of your window frames:

1. Start by Removing Loose Dirt: Use a soft brush or vacuum with a brush attachment to remove loose dirt, dust, and debris from frames, sills, and tracks.
2. Prepare a Cleaning Solution: Mix mild, pH-neutral soap or specialized UPVC cleaner with warm water. Avoid harsh chemicals like bleach, acetone, or abrasive cleaners that can damage UPVC.
3. Clean the Frames: Use a soft cloth or sponge dampened (not soaking) with your cleaning solution to wipe down all frame surfaces.
4. Pay Special Attention to Crevices: Use a soft toothbrush to reach into corners and joints where dirt can accumulate.
5. Rinse Thoroughly: Wipe with a clean, damp cloth to remove any soap residue.
6. Dry the Frames: Use a lint-free cloth to dry the frames completely to prevent water spots.

Glass Cleaning for Streak-Free Results

For sparkling, streak-free glass:

1. Choose the Right Day: Clean windows on cloudy days when possible. Direct sunlight can cause cleaning solutions to dry too quickly, leaving streaks.
2. Use the Right Tools: A squeegee, microfiber cloth, or lint-free paper towels work best.
3. Prepare a Cleaning Solution: Either use a commercial window cleaner or make your own by mixing one part white vinegar with ten parts water.
4. Apply the Solution: Apply sparingly with a cloth or sponge.
5. Squeegee Technique: If using a squeegee, start at the top and pull down in a straight line, wiping the blade after each stroke. For the final passes, use horizontal strokes.
6. Buff to Perfection: Use a dry microfiber cloth to buff away any remaining streaks or water spots.

Hardware Maintenance: Ensuring Smooth Operation

Lubricating Moving Parts

Window hardware needs regular lubrication to operate smoothly and prevent wear:

• What to Lubricate: Hinges, locks, handles, and any moving mechanisms.
• Frequency: At least once a year, more frequently in coastal areas or if you notice stiffness.
• Recommended Lubricants: Silicone spray or light machine oil. Avoid using WD-40 as a long-term lubricant (it's great for cleaning but not for ongoing lubrication).
• Application Method: Apply lubricant sparingly, wiping away any excess to avoid attracting dirt.

Checking and Tightening Hardware

Over time, the repeated motion of opening and closing windows can loosen screws and fixings:

• Regular Inspection: Check all visible screws, handles, and hinges every 6-12 months.
• Tightening: Use the appropriate screwdriver to gently tighten any loose screws. Be careful not to overtighten, which can strip the holes.
• Replacement: If you notice any damaged or severely corroded hardware, arrange for professional replacement rather than waiting for complete failure.

Adjusting Hinges

Windows can sometimes drift out of perfect alignment due to settlement or heavy use:

• Signs of Misalignment: Difficulty closing, drafts, or uneven gaps around the window.
• Basic Adjustments: Many modern windows have adjustable hinges. Look for small hex screws that allow for height and lateral adjustments.
• Seek Professional Help: If you're unsure about making adjustments yourself, contact a window professional. Improper adjustments can affect security and weather sealing.

Seal and Weatherstripping Maintenance

Inspecting Seals

The rubber seals (gaskets) around your windows are crucial for energy efficiency and preventing water ingress:

• Visual Inspection: Check for cracks, splits, shrinkage, or areas where the seal has come away from the frame.
• Performance Testing: On a windy day, hold a lit candle or incense stick near the window edges (being careful of curtains and other flammables). Flickering smoke indicates air leakage.
• Frequency: Inspect seals at least once a year, ideally before winter.

Cleaning and Preserving Seals

Proper maintenance can extend the life of your window seals:

1. Cleaning: Gently clean rubber seals with mild soapy water and a soft cloth to remove dirt and prevent cracking.
2. Conditioning: Apply a silicone-based or rubber conditioner (available at most hardware stores) to keep the rubber supple and prevent it from drying out and cracking. Never use petroleum-based products like Vaseline, which can degrade rubber over time.
3. Re-seating: If a seal has come loose but is otherwise in good condition, gently push it back into place.

Drainage System Maintenance

Understanding Window Drainage

Modern windows have built-in drainage systems to channel away any water that penetrates the outer seals:

• Drainage Channels: Small channels in the window frame bottom direct water outward.
• Weep Holes: Small holes on the exterior of the frame allow water to exit.

Clearing Blockages

Blocked drainage systems can lead to water ingress and damage:

1. Locate the Drainage Holes: Look for small holes on the outside bottom of the window frame.
2. Clear Debris: Use a small brush or the tip of a bent paperclip to gently clear any visible blockages from weep holes.
3. Flush the System: Pour a small amount of water into the track with the window closed to ensure it drains properly through the weep holes.
4. Vacuum Tracks: Use a vacuum with a narrow attachment to remove debris from window tracks.

Condensation Management

Understanding Condensation

Condensation occurs when warm, moist air meets a cold surface:

• External Condensation: On the outside of energy-efficient windows, especially in the morning. This is actually a sign your windows are working properly by keeping heat inside.
• Internal Condensation: On the room-side surface, indicating high humidity levels in your home.
• Condensation Between Panes: If you see condensation or fogging between the glass panes, this indicates seal failure and requires professional attention.

Reducing Condensation

Managing indoor humidity helps prevent condensation problems:

• Ventilation: Use extractor fans in kitchens and bathrooms. Open windows briefly each day to allow moisture to escape.
• Consistency: Maintain a consistent temperature throughout your home.
• Dehumidifiers: Consider using a dehumidifier in problem areas.
• Trickle Vents: If your windows have trickle vents, use them to provide background ventilation.

Seasonal Maintenance Schedule

Spring

• Thorough cleaning of frames and glass after winter
• Check and clear drainage channels and weep holes

Special Considerations for Different Window Types

Casement Windows

Windows that swing open like a door require special attention to hinges:

• Keep hinge mechanisms clean and well-lubricated
• Check the casement stays (the arms that hold the window open) for any wear
• Ensure locking points engage properly for security and weather sealing

Sliding Windows

Sliding sash or patio-style windows need attention to their tracks:

• Keep tracks clean and free of debris
• Apply silicone spray to tracks for smooth operation
• Check rollers for wear and smooth operation

Tilt and Turn Windows

These versatile windows have complex hardware that benefits from regular maintenance:

• Ensure the multi-point locking system is clean and lubricated
• Check that both the tilt and turn functions operate smoothly
• Pay special attention to the corner mechanisms where the two functions meet

Conclusion

Regular maintenance is the key to ensuring your windows remain beautiful, functional, and energy-efficient for many years. By incorporating these simple maintenance tasks into your home care routine, you can protect your investment and avoid costly repairs or premature replacement.
