Maintaining your timber sash and case windows can significantly extend their lifespan, enhance their appearance, and ensure they function smoothly. At Hilston and Bennett, we’re dedicated to helping homeowners in Central Scotland keep their bespoke windows in top condition. Here are some practical maintenance tips you can undertake at home, plus guidance on when to call in the experts.
Maintenance You Can Undertake at Home
Cleaning
Regularly cleaning both the timber and glass surfaces of your sash windows will keep them looking great and functioning properly. Use a quality glass cleaner and a microfiber cloth to clean the glass, while timber frames can be gently wiped with warm, soapy water. Afterward, make sure the timber is completely dry to prevent moisture absorption, which can lead to decay.
Painting
To preserve the integrity and appearance of timber sash windows, painting is essential. Regularly painting the timber prevents deterioration; however, the accumulation of multiple paint layers can inhibit smooth opening and closing of sliding sashes. If paint layers build up, they can be removed with:
– Sandpaper or a thin-bladed scraper to carefully thin excess paint layers.
– Alkali paint strippers or gentle heat from an air gun if more thorough removal is required. When using heat, be cautious to avoid damaging the glass.
Further Sash & Case Window Maintenance Advice
While certain maintenance tasks are manageable at home, some signs indicate the need for expert assistance. Regularly check for the following issues, as they may need professional attention:
– Gaps that cause drafts or uneven meeting rails
– Opening joints in the sashes or frame
– Broken sash cords or damaged/missing timber
– Defective glazing putty leading to loose panes
– Sashes that close by gravity rather than staying open
– Decay in the cill, parting beads, or sash frame
– Shutters that won’t open or have split panels
– Timber decay in shutters, linings, or cills
– Damp plaster in recesses behind shutters
Addressing these issues promptly can prevent larger problems down the line and ensure your sash and case windows remain a beautiful and functional feature of your home.
