Sash windows are a timeless and elegant feature that have a classiccharm which enhance both the interior and exterior of your home. However, like other areas of your home, sash windows require regular maintenance to make sure they last and also look great. In this guide, we will walk you through the essential steps and best practices for maintaining your sash windows so they remain in top condition for years to come.

Regularly Clean and Inspect Your Windows:

Keeping your sash windows clean is crucial for their overall maintenance. Dirt, dust, and grime can build up on the glass panes, frames, and sashes, affecting their appearance and functionality. We recommend you follow these steps for regular cleaning:
a. Start by vacuuming the frames and sashes to remove loose dirt and debris.
b. Use a mild detergent mixed with warm water to wipe down the frames and glass panes.

c. For stubborn stains or dirt, consider using a non-abrasive cleaner such as HG Black Mould Remover spray.
d. Gently dry the windows with a soft cloth to prevent watermarks. Screwfix provides a range of high-quality cleaning products for windows.

Repair and Replace Damaged Window Components:

Over time, various components of sash windows may require repair or replacement. It’s important to address these issues promptly to prevent further damage. Here are some common repairs you may encounter:
a. Fixing loose sashes: If your sashes are not closing properly or are wobbly, it may be due to loose cords or pulleys. Tighten or replace them as needed.
b. Repairing damaged putty: Cracked or damaged putty can lead to air leaks and moisture penetration. Remove the old putty and replace it with a fresh layer.
c. Replacing broken glass panes: Broken or cracked glass panes should be replaced immediately to maintain the window’s integrity.

Weatherproof Your Windows:

Ensuring your sash windows are properly weatherproofed is vital to protect them from the elements and maintain energy efficiency. Follow these steps to weatherproof your sash windows:
a. Inspect the window frames for any gaps or cracks. Seal them using a suitable sealant such as Unibond Outdoor Window & Door Sealant.
b. Consider adding weatherstripping around the sashes to prevent drafts and improve insulation.
c. Apply a high-quality exterior paint or stain to protect the wood from moisture and UV damage. For exterior surfaces we recommend Zinsser AllCoat Exterior Gloss

Lubrication and Window Hardware Maintenance:

Smooth operation of sash windows relies on well-maintained hardware and proper lubrication. Follow these tips to keep your window hardware in optimal condition:
a. Regularly clean and lubricate the pulleys, hinges, and other moving parts using a silicone-based lubricant such as WD-40.
b. Check the condition of cords or chains, and replace them if they are worn or damaged.
c. Ensure that locks and latches are functioning correctly and tighten any loose screws.

Painting and Finishing Your Windows:

Applying a fresh coat of paint or stain not only enhances the appearance of your sash windows but also protects them from moisture and decay. Follow these guidelines for painting and finishing:
a. Remove any loose or flaking paint using a scraper.
b. Sand the surfaces to create a smooth and even base.
c. Apply a high-quality primer to improve adhesion.
d. Finish with multiple coats of paint or stain, ensuring complete coverage and protection. For internal surfaces we recommend Little Green’s Intelligent Eggshell which gives a low sheen finish with exceptional durability. Formulated to resist moisture, staining and general wear and tear and is also environmentally friendly.

Maintaining sash windows is essential for preserving their beauty, functionality, and longevity. By following the steps outlined in this guide, you can ensure that your sash windows remain in optimal condition for years to come. Remember to regularly clean and inspect your windows, address repairs promptly, weatherproof them, maintain the hardware, and apply proper painting and finishing techniques.

Regular maintenance not only protects your investment but also enhances the overall charm and value of your home. So, take the time to care for your sash windows, and they will continue to be a delightful feature in your living space for generations to come.
