Timber windows and doors are built to last. With the right care and regular maintenance, they can deliver decades of reliable performance while retaining their appearance.
At Sashless, our timber windows and doors are designed with longevity in mind, with an expected service life of up to 60 years. Achieving that depends on the quality of the product, the conditions it is exposed to and, importantly, how well it is maintained.
The good news is that looking after timber windows and doors needn’t be complicated. A few straightforward checks throughout the year can help protect the finish, keep the hardware working smoothly and identify small issues before they become bigger problems.
Every month
A quick visual check helps keep the essential components in good condition.
- Check weather seals and glazing tapes. Wipe away dirt and debris using a soft cloth to help maintain a clean contact surface.
- Keep drainage channels clear. Remove any leaves, dust or other debris from drainage holes and channels to allow water to drain away freely.
- Look for anything unusual. Check for visible damage, loose components or signs of water collecting where it shouldn’t.
Every three months
Give your windows and doors a gentle clean.
Clean external timber surfaces with a mild soap solution and a soft cloth, then rinse with clean water. Avoid abrasive cleaners, harsh chemicals and pressure washers, which can damage the decorative finish or force water into joints.
When cleaning upper floors, use suitable access equipment and avoid placing ladders directly against window frames or cills.
Every six months
Check the hardware and protect the finish.
- Clean and lubricate the ironmongery. Hinges, handles, locking mechanisms and other moving parts should be checked and maintained in accordance with the hardware manufacturer’s recommendations. Use the specified lubricant for each component. Properties in coastal or high-pollution environments may require more frequent attention.
- Inspect the paint or stain finish. Pay particular attention to exposed areas, including the upper surfaces of cills and glazing beads. Look for cracking, flaking, worn patches or exposed timber, and address any deterioration promptly using a compatible repair system.
- Check the overall condition. Look for damage to seals, joints and timber surfaces, and investigate any signs of persistent moisture or water ingress.
Keeping the protective finish in good condition is particularly important. Addressing localised wear early can help prevent moisture reaching the timber and reduce the likelihood of more extensive remedial work.
Two simple habits that make a difference
Close and lock doors correctly. Where multipoint locking is fitted, engage the locking mechanism as intended rather than relying on the latch alone. This helps the door close securely and operate as designed.
Keep a maintenance record. Record inspections, cleaning, lubrication and any repairs, retaining receipts where applicable. This provides a useful history of the care your windows and doors have received and can help demonstrate that maintenance requirements have been followed.
Looking after your warranty
Regular maintenance is important not only for the appearance and performance of your windows and doors, but also for protecting your warranty cover.
Sashless offers extended warranty cover, including 30 years against rot and 10 years for specified manufacturing defects, sealed glazing units and ironmongery, subject to the applicable warranty terms and conditions.
The required maintenance, permitted cleaning products and recoating intervals can vary depending on the product, finish and environmental exposure. It is therefore important to follow the manufacturer’s guidance and address any issues promptly.
For full details of your cover and the maintenance requirements that apply to your installation, please refer to your Sashless warranty documentation.
