Sash window refers to the type of window that contains movable panels called sashes. These panels open and close by sliding up and down or swinging outward. You will commonly find these windows in older homes, especially those with Victorian or Georgian styles. Although these are exquisite and elegant, they are prone to deterioration. Wood, which is the common material used for this window type, absorbs moisture in the atmosphere. This means that it can rot, swell, shrink, or get distorted after some time. When this happens, you need to repair the window to make it go back to its top working condition.
First, you need to unscrew the moldings in the lower sash to pull it out. Remove the sash chains from both of the sides and tie them into a knot. Next, you take off the vertical strips that hold the upper sash. Pull out the upper sash. Remove also the chains from the upper sash.
Remove all the sash hardware. It is imperative that you place them in secured plastic bags so you don’t lose any important part. Don’t forget to label the bags accordingly so you don’t get confused when it’s time to return the window.
Now for the repair, set a heat gun with a nozzle shield to Double Glazing Sash Windows Thanet medium and then use it to soften the glaze compound on the window. Scrape away the glazing compound using a putty knife. Remove from the wood and slide the glass out. Label the glass with a temporary market to indicate which side goes where.
Clean loose sash joints. Remove rotten wood with the use of a rotary tool. Apply a coat of epoxy wood primer on the wood joints. Let the primer site for about 20 minutes. Mix together equal parts of epoxy wood filler with a plastic scraper. Spread the epoxy evenly until the joint is restored to its original shape. After the window has been repaired, you can reinstall the chains and the cords. Then put back the moldings to the right places.
Your job doesn’t end with repairing the windows. You also need to ensure that your windows are clean and dirt free at all times.
