Wooden Sliding Sash Windows Care and Maintenance Checklist

  1. Check the weatherstrip* to make sure it is in good conditions.
  2. Look for damages on the window’s interior and exterior painted finish. Sporadic maintenance might be required.
  3. Check for caulking over the frames of the window.
  4. Make sure that the window and all hardware (sash locks, trickle vents) operate smoothly.
  5. See if visible hardware screws are securely tightened.
  6. Remove any dust, sand or dirt from the window hinges, sills and frames.
Weatherstrip is a flexible and important part of the window design which reduces the space between sashes and frames to block air and water infiltration.

Cleaning Wood Window Surfaces

You can clean superficial dirt by washing your Cardinal sash window with water and a soft-bristled, long-handled brush. Difficult accumulations can be cleaned with a mild mix of water and household detergent. Cleaning products containing solutions of alcohol and water are also efficient.

Warm Colours Windows

The surface of a wooden sliding sash window is vertically painted, which requires special attention to avoid streaking the finish. For that reason, we recommend that you wash your Cardinal sash window from the top to the bottom and rinse the surface with abundant clear water to remove excess cleaning solutions. Long detergent contact can damage the paint finish of your wooden window.

You might need to use stronger cleaning products to remove grease or oily materials. Check the labels for solvents or abrasive-type compounds and avoid any cleaners that contain ammonia, chemicals or any harsh substances. Such strong detergents can cause damage to your wood window finished surfaces.

Small Repairs to Your Wood Window

If your wooden window shows small damaged areas to the painted finish, such as caulking and scratches, you can perform small repairs. Trim off any old, free caulking and seal any cracks with a high-quality caulk filler. Retouch the window with a matching colour, high-quality latex primer and Teknos paint.

Protect the weatherstrip from any solvent-containing materials when using paints, stains and varnishes for repairs. These products can cause the weatherstrip to lose its flexible properties.

Always take safety measurements when carrying out maintenance, such as protective eyewear and clothing, as well as careful operation of ladders. Also, remember to follow the manufacturer’s instructions, dispose precautions and safety recommendations when working with primers, paints, stains and cleaning solutions.

I ordered 15 sliding sash windows for my home refurbishment project and had my builder install the windows for me. I think I spent hours playing around with the different design options on the window builder! I absolutely love my new windows!
