Entretien de vos fenêtres à guillotine simple : conseils de lubrification, de peinture et d'entretien

Keeping your single-hung windows well-maintained ensures they operate smoothly, look great, and last longer. Regular care, including cleaning, lubricating moving parts, and occasional painting, prevents common problems like sticking and drafts.

This guide provides practical steps for maintaining your single-hung windows, helping you keep them in top condition.

Why Maintain Your Windows?

Regular maintenance offers several benefits:

• Fonctionnement fluide : Prevents sticking and makes windows easier to open/close.
• Longévité: Protects materials (wood, vinyl) from wear and weather damage.
• Efficacité énergétique: Ensures seals remain effective, reducing drafts.
• Apparence: Keeps windows looking clean and fresh.
• Prevents Costly Repairs: Addressing minor issues early stops them from becoming bigger problems (See common window problems).

Outils et matériaux nécessaires

Gather these items for general maintenance:

Lubrification:

• Silicone Spray Lubricant (Recommended): Won’t attract dirt like oil-based sprays.
• Clean, dry cloths
• Vacuum cleaner with brush/crevice tool

Nettoyage: (See full guide de nettoyage des fenêtres for more detail)

• Mild soap or window cleaning solution (or vinegar/water mix)
• Seau
• Microfiber cloths or sponges
• Squeegee (for glass)

Painting (If Needed):

• Fine-grit sandpaper (220+)
• Painter’s tape / Masking liquid
• Appropriate Primer (wood or bonding primer for vinyl)
• Appropriate Exterior-Grade Paint (wood or vinyl-safe paint)
• Paintbrushes (angled sash brush helpful) / Small roller / Sprayer
• Drop cloths
• Cleaning supplies (soap, water, possibly acetone for vinyl prep)
• Safety Gear: Gloves, safety glasses, potentially a respirator

Step 1: Regular Cleaning (The Foundation)

Clean windows prevent buildup that causes sticking.

1. Vacuum Tracks: Open the window. Use a vacuum with a brush or crevice tool to remove all loose dirt, dust, cobwebs, and debris from the side jamb tracks (where the sash slides) and the sill.
2. Wipe Down Tracks & Frame: Mix mild soap and warm water. Use a damp cloth or sponge to wipe the tracks, sill, and window frame (both sash and main frame). For stubborn grime, a soft brush can help.
3. Rinse (If Necessary): Wipe with a clean, damp cloth to remove soap residue.
4. Dry Thoroughly: Use a clean, dry cloth to wipe everything dry, especially the tracks.
5. Nettoyer la vitre : Clean the window panes last using glass cleaner or a vinegar/water solution and a squeegee or microfiber cloth.

Frequency: Clean tracks seasonally (spring/fall) or more often in dusty areas. Clean glass as needed.

Step 2: Lubricating for Smooth Operation

Lubrication prevents sticking and makes windows effortless to open and close. Always clean tracks avant lubricating.

1. Choose the Right Lubricant: Utilisez un silicone-based spray. Crucially, DO NOT use oil-based lubricants like WD-40, as these attract dirt and can gum up the tracks over time. Pure paraffin wax (like canning wax or ski wax) is another option for rubbing on contact points.
2. Apply Sparingly:
   • Best Method: Spray the silicone lubricant onto a clean, dry cloth, NOT directly into the track.
   • Wipe the cloth along the inside surfaces of the jamb tracks where the sash slides.
   • Wipe any weatherstripping contact points lightly.
3. Distribute: Slide the bottom sash up and down several times to evenly distribute the lubricant.
4. Wipe Excess: Use a clean cloth to wipe away any visible excess lubricant.

Frequency: Lubricate once or twice a year, or whenever windows start to feel stiff.

Step 3: Painting Single-Hung Windows (When Necessary)

Painting protects wood windows and can refresh the look of vinyl (with precautions).

A. Painting Wood Windows:

1. Préparer la surface : Clean the window thoroughly. Scrape any loose paint. Sand smooth (use fine-grit paper). Wipe away dust.
2. Prime: Apply a quality exterior wood primer to bare wood spots or the entire surface for best results. Let dry completely.
3. Peinture: Apply 1-2 thin coats of quality exterior paint suitable for wood. Use an angled sash brush for control.
   • Technique: Paint sashes first, then the frame. Work from top to bottom.
   • Avoid Painting Shut: Leave the sash slightly open while painting and drying. Move the sash periodically during the drying process to prevent it from sticking to the frame or weatherstripping. Do not paint weatherstripping.

B. Painting Vinyl Windows:

1. Check Warranty: Important: Painting vinyl windows may void the manufacturer’s warranty. Check first!
2. Choose Correct Paint: Critical: Toi doit use paint specifically labeled “vinyl-safe”. These are often lighter colors, as dark paints can cause excessive heat absorption and warp the vinyl. You’ll also need a bonding primer suitable for vinyl/plastic. Consult a knowledgeable paint store employee.
3. Préparer la surface : Clean the vinyl soigneusement (mild soap/water, or specific vinyl cleaner). Lightly scuff the surface with very fine sandpaper (220-grit or higher) or a liquid deglosser/etcher to help primer adhere. Wipe clean.
4. Mask Carefully: Use painter’s tape to mask off glass, weatherstripping, and hardware precisely.
5. Apply Bonding Primer: Apply a thin, even coat of bonding primer (spray primer often gives the smoothest finish). Let cure completely per manufacturer instructions.
6. Apply Vinyl-Safe Paint: Apply 2-3 thin coats of the vinyl-safe paint (spray paint is often preferred for vinyl). Allow adequate drying time between coats. Avoid thick coats.
7. Retirer le ruban adhésif : Remove painter’s tape carefully once the paint is dry but not fully cured (usually within 24 hours) for the cleanest lines. Score edge with a utility knife if needed.

Step 4: Inspecting Seals and Hardware

Regular checks prevent bigger issues.

• Coupe-froid : Look for compressed, cracked, torn, or missing sections around the operable sash. Replace damaged weatherstripping to prevent drafts.
• Calfater: Check the caulk joints where the window frame meets the exterior siding and interior wall. Re-caulk any cracked or shrinking areas.
• Matériel: Ensure locks and keepers engage properly. Tighten any loose screws. Check balances for smooth operation. (If window won’t stay up, see balance repair guide).

When Maintenance Isn’t Enough

While regular care extends window life, sometimes replacement is the better option, especially if:

• Frames are significantly damaged, rotted, or warped.
• Repairs are becoming frequent or complex. (Compare replacing parts vs. the whole window unit).
• Windows are extremely inefficient despite maintenance.
• You desire a significant upgrade in style, features, or energy efficiency that only [ordering new custom single-hung windows] can provide.

Conclusion

Consistent maintenance – regular cleaning, appropriate lubrication, and timely painting/sealing – is key to keeping your single-hung windows functioning smoothly and looking their best for years. These simple steps can prevent sticking, drafts, and premature wear. If you encounter major damage or complex mechanical issues, don’t hesitate to consult a window repair professional.
