Additional Maintenance Tips For Your Replacement Pella Fixed Sash
By following these additional maintenance tips, you can ensure that your replacement Pella fixed sash remains in top condition and provides long-lasting performance.
Regular Cleaning
Regular cleaning of your replacement fixed sash can help to prevent dirt and debris from building up and affecting its operation.
Use a soft cloth or sponge and mild soap to clean the sash and frame gently.
Avoid using harsh chemicals or abrasive materials that could damage the surface of the sash.
Lubrication
Lubricating your fixed sash’s moving parts can help ensure smooth and easy operation.
Use a silicone-based lubricant or a dry Teflon spray to lubricate the tracks and hinges of the sash.
Avoid using oil-based lubricants, which can attract dirt and debris.
Sealing
Ensuring a tight seal between your fixed sash and the frame can help to prevent drafts and improve energy efficiency.
Check the weatherstripping and seals around the sash and replace any damaged or worn parts as needed.
Use an exterior sealant to seal any gaps or cracks around the frame.
Avoid Slamming
Avoid slamming your replacement fixed sash, as this can cause damage to the frame, hardware, and glass.
To avoid this, always operate the sash smoothly and gently, and ensure that the sash is fully closed before locking it.
Trim Nearby Trees
Trees and branches near your windows can cause damage to the sash and frame, as well as the glass.
Keep nearby trees trimmed and pruned to prevent branches from scraping against the sash or breaking the glass.
Check the Hardware
The hardware on your replacement fixed sash, such as the locks, hinges, and handles, can become loose over time.
Check the hardware periodically and tighten any loose screws or bolts. If the hardware is damaged or broken, contact a professional for replacement.
