Tips for caring for plastic windows in summer

Summer brings open windows, dust, heat and strong sunlight. To keep PVC windows looking good and working properly, adopt a few simple maintenance habits. These steps help preserve seals, hardware, and glass clarity while reducing the chance of problems later.

Why summer maintenance matters

• High temperatures and UV exposure can age seals and affect fittings.
• Pollen, sap and dust settle on frames and sills more actively.
• Frequent ventilation increases wear on seals and drainage channels.

Regular summer care prolongs service life and prevents small issues from becoming costly repairs.

Weekly quick care

• Wipe frames and sills with a soft cloth and mild detergent solution.
• Avoid abrasive cleaners and solvents (acetone, paint thinner).
• Remove insect residues and pollen with a soft sponge or brush.

Deep cleaning every 1–3 months

1. Wash profiles with warm water and a mild detergent.
2. Clean glass with non-abrasive glass cleaner and soft cloths.
3. Check and clean drainage holes: blow out or flush with a gentle jet of water.

Caring for seals

• Wipe seals gently — do not stretch or rub them aggressively.
• Apply silicone lubricant or a rubber conditioner 1–2 times a year (after hot spells is recommended).
• Replace seals that have cracked or lost elasticity.

Lubrication and hardware check

• Inspect handles, hinges and locks for smooth operation.
• Use silicone-based or graphite lubricants for moving parts (avoid household oils).
• If closing pressure seems uneven, get a professional adjustment—basic checks can be done visually.

Protection from heat and UV

• Prolonged sun exposure can discolor seals and heat profiles.
• Use external or internal sun protection: roller blinds, venetian blinds, awnings.
• Close blinds during the hottest hours to reduce thermal stress on the frame.

Ventilation and condensation control

• Use short cross-ventilation (5–10 minutes) to refresh air without overheating interiors.
• Avoid leaving windows in micro-vent mode in high-dust conditions.

What to do if you find leaks or damage

• Water seeping from seals or condensation inside a sealed double-glazed unit may indicate a failed unit — call a professional.
• If mold appears on window reveals, clean and then identify the moisture source.

Common mistakes to avoid

• Using chlorine-based or abrasive cleaners damaging profiles and hardware.
• Neglecting drainage, leading to water accumulation in frames.
• Over-application of oil-based lubricants that attract dirt.

FAQ

How often should I clean my windows in summer?

Weekly wiping and a more thorough cleaning every 1–3 months is recommended depending on pollution levels.

Can I wash windows in direct sunlight?

It’s better not to: cleaners dry too fast and leave streaks. Clean during cooler parts of the day.

How do I remove sap or sticky residues from frames?

Use warm soapy water and a soft cloth. For stubborn residues, specialized plastic-safe cleaners work well.

My handle is stiff — what should I do?

Try a silicone spray on the moving parts. If stiffness remains, have a technician check alignment and wear.

How to protect windows from overheating?

Install blinds or external shading and ventilate briefly during cooler hours to reduce thermal load.

Summer maintenance checklist (short)

• Weekly: wipe frames and glass.
• Monthly: check drainage and seals.
• Annually: lubricate hardware and inspect seal condition.
