Window Sash Repairs Most homeowners don't think much about window sashes — as long as they are closed, open, and keep outside air out and the inside air in. As time passes window sashes may become worn out and lead to drafts, air leaks, or even sashes that are stuck. The author makes use of the sash which is supported on an easel to work the glazing points into the gap. He also scrapes off paint and then applies a wood preservative on the frame. Sash Weights If your windows are not opening and closing smoothly, or are stuck the way they should, a defective counterbalancing system could be the cause. This could be due to an ailing or damaged sash chain, a misaligned or unattached sashweight, or a broken or cracked pulley. The sashweights are tiny boxes made of cast iron that support the counter-weight system as well as support the sash. They are found in the bottom rails of every window frame, and are covered by a wooden access panel which can be opened to reveal their position. The panels can be removed to allow access to the sash-weight pockets in order to clean and repair or replace them. There could be an issue with the sashweights, if you've had your sash windows long enough. They might be sagging or catch. This can be caused by the weights being too heavy (they are supposed to be slightly heavier than the top sash) or by having them installed incorrectly (some people disabled their weight systems by cutting them and taking the weights out to save money or turn them into scrap metal). To remedy this issue to fix this issue, take off the stops (the trim that runs along the inside of the window at the point where it joins with the frame to keep it in place). Put them away. It is important to do this gently so as to not damage the appearance of the overlapping rails. Then, you can use a hammer for separating the stiles and rails and check them for damage. After you've checked the stiles and rails, lay down a few dust sheets and begin working on the sash itself. Begin by removing the wood pegs from the mortise and tenon joints with pins and a hammer or screwdriver. After removing the pegs you can begin disassembling the sash. Remove the sash stop moldings and any sash cords still in place. Next, you will need to weigh the sash to determine the amount of weight it needs for proper functioning. You can find vintage weights for replacement on the internet or at a few home improvement stores, but ensure that you purchase the right size so as not to under or over weigh the sash. Sash Cords Sash cords that have worn out or broken can cause problems with the sash window. The weights put constant pressure on the sash cords and this could cause them to break over time. The sashes won't open or close as easily if cords break. The issue could be caused due to excessive force, aging or lack of maintenance or the buildup of moisture. It is essential to replace the old cords during window sash repairs with new cords made of a material that is strong and resistant to moisture. Start by removing the interior stop strips, the thin wood strips which hold the sashes in the frame, using a utility blade and a chisel. Remove the stops from the sashes carefully, and be on the lookout for cracked or broken ones. Once the stops are removed, you will be able to access the sash weights through an access panel that is cut into the bottom of the frame or by opening the jamb, and then removing the cover that covers the weight pocket. Accessing the sash cords takes some effort however it's not too difficult with the right tools and patience. First, take off the old cords by cutting them near their knots, and then pulling them away. Then, take the sash from the frame and put it aside. After the sash has been removed and you have pulled it down, grab the staff bead (the nail that prevents the sash from falling) and insert one nail that is about 1 foot into the hole in the staff bead. This will keep the sash in place while you finish stringing counterweights. After installing the upper sash then reattach the sash cords and ensure that the sashes are properly balanced and move smoothly. Then, you can reinstall the lower sash, and repeat the process, checking that the sashes are properly sitting and moving smoothly. Reattach the sash cables once you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole on the sash. Repeat this process on the opposite side of the sash to ensure that the sashes work as intended again. Air and drafts Leaks Over time, the materials that connect sash windows to the home's frame deteriorate which can cause drafts and energy loss. A thorough inspection can reveal problem areas and guide the repair options for your window sash. Your comfort level and level will determine if you can manage yourself or require assistance from a professional for window repair. The historical status of your property and structural integrity concerns also impact the scope of work that is required. If cold air enters through a drafty window, your furnace has to be working overtime to keep your home warm. This inefficiency eats into your heating bills and compromises the efficiency of your home's HVAC system. Moreover, drafts disrupt your indoor comfort and can degrade the quality of your indoor air by bringing in outdoor pollutants, allergens and humidity. A common sign of a drafty windows is the sensation of cold air circulating through your home regardless of windows and doors being closed. Other signs to look for are a fluctuation in the temperature of your room near the window, and condensation around the frame or sill. Fixing sash secondary glazing can be an easy task that will reduce your energy bills and increase comfort inside. The first step is to examine the window's exterior. Look for areas of bare wood or cracked caulking that exposes the window to cold air. Examine the sash's connection to the frame including the parting beads and staff bead. Examine the condition of weather stripping on these points (felt strips or tape) to determine if they're intact and functional. If not, it's time to be replaced. Then, think about the condition of glazing putty. It is a hard putty that holds panes glass in place. Examine for cracks or crumbling that expose the sash to moisture, which can cause mold issues and damage to the glass of windows. To resolve the issue, apply a bed of fresh glazing putty onto the inside of your window. With a flat-blade screwdriver push the glazing points into position to hold them. Wrap a fabric or piece and then foam around each point. This will act as insulation against cold air.

After you have removed the parting beads, you'll have to remove the covers for your pockets. They are pieces of wood within the frame, low down which allow access to the sash weights and are normally nailed in place – they may also be snagged with paint, so you have be cautious.
