Window Sash Repairs Many homeowners don't care about window sashes as long as they are closed, open, and keep the outside air out and the air inside in. However, over time, they can start to wear out, causing drafts, air leaks, or even sashes sticking. The author uses a sash that is propped up on an easel to work glazing points into the gap. He also scrapes paint off and then applies a wood preservative on the frame. Sash Weights If windows aren't opening or closing with ease or are sagging, a faulty counter-balancing system could be the cause. This can be caused by a damaged or missing sash chain, a misaligned or unattached weight, or a damaged or cracked pulley. The sashweights are small, rounded boxes made of cast iron that support the counter-weight system and support the sash. The sash weights are situated on the bottom rails of every window frame. They are protected by an unfinished wooden panel which can be removed to reveal their position. The panels can also be removed to gain access to the sash weight pockets for cleaning, repairs or replacement. If you've had sash windows for some time, you may have an issue with the weights on the sash that cause them to lean or catch. This can be caused by the weights being too heavy (they are supposed to be a little heavier than the top sash) or by having them installed incorrectly (some people have disabled their weight systems by cutting them and removing the weights to save money or turning them into scrap metal). To fix this issue, first take off the stops (the trim along the inner edges of the window where it meets the frame and keeps it in place) and set them aside. This requires you to be gentle so as to not damage the appearance of your overlapping rails. Then, you can use a hammer for separating the stiles and rails and inspect them for damage. Once you've inspected the rails and stiles, 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 the pegs have been removed, you can begin to disassemble the sash by taking out the stop moldings for sash as well as removing the sash cord knots that are attached and, finally, removing the sash itself. Next, you will need to weigh the sash in order to determine the amount of weight it needs for proper functioning. You can find vintage weights for sash replacement online or at a few home improvement stores, but ensure that you purchase the right size so as not to over or under weight the sash. Sash Cords Sash cords that are worn or broken can cause sash window issues. The weights put pressure on the sash cords and this can cause them break over time. If the cords break, sashes won't be able to open and close easily. The problem can be caused by a variety of reasons like excessive force, aging, a lack of maintenance, and the accumulation of moisture. It's important that you replace the old cords during window sash repair by new ones made from a material that is durable and resistant to moisture. Start by removing the internal stop strips, thin wood strips which hold the sashes in place Utilizing a utility blade and a Chisel. Remove the stops from the sashes with care and be on the lookout for any broken or cracked ones. After removing the stops you can gain access to the sashweights by opening up the jamb or taking out the weight pocket. It takes a little extra effort to reach the sash cords, but with the right tools and a little bit of patience it is not difficult. Take the old cords out first by cutting them in their knots and then pulling them out. Then, remove the sash from the frame and put it aside. When the sash is removed then pull it back down on the staff bead (the nail that keeps the sash from falling) and insert a nail about 1 foot into the staff bead hole. This will stop the sash from slipping away while you string the counterweights. Reattach the sash string after reinstalling upper sash. Check that the sashes move smoothly and are balanced. Reinstall the lower sash, and repeat the process. Check that the sashes are properly seated and are moving in a smooth manner. Reattach the sash cable after you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole on the sash. Repeat this process for each side of the sash until all the cords are replaced and the sashes are functioning normally. Air and drafts Leaks Over time, the materials that secure sash windows to your frame of your home deteriorate which can cause drafts and loss of energy. A thorough inspection will identify the problem areas and help you determine the best options for repairs to your window sash. Your comfort preferences and experience level determine whether you are able to manage window repairs to your sash or require professional assistance. The scope of work required is also affected by the history of the property's condition and structural strength. When cold air sneaks in through a drafty window your furnace is forced to perform overtime to keep your home warm. This inefficiency increases your heating bills, and can compromise the efficiency of your HVAC system. Additionally, drafts can disrupt your indoor comfort and can degrade the quality of indoor air by pushing into the outdoor air pollutant, allergens, and humidity. A drafty window can be identified by the feeling of cold air rushing into an area, even though all windows and doors are shut. Other telltale signs are a change in temperature near the window, as well as condensation on the sill or frame. Fixing drafty windows is a simple task, which can reduce your energy costs and increase comfort inside. The first step is to look at the exterior of the window. Examine for bare wood and areas where the old caulking has cracked, exposing the gap to cold air. Examine the sash's connection to the frame including the parting beads and staff bead. Check the condition of the weather stripping (felt strips or foam tape) at these points to determine if they are intact and working. If not, it needs to be replaced. Take a look at the condition of the glazing putty. This is a hard putty that is used to hold panes of tempered glass in place. Look for cracks and crumbling that can expose the sash's exterior to moisture. This could lead to problems with mold and damage to the glass. To fix the issue, apply a bed of fresh glazing putty to the inside of your window. To secure the glazing points, make use of a flat-bladed screwdriver push them into place. Then, wrap a piece of foam and fabric around each point to form an insulation layer against cold air. Aesthetics Window sash repair can give older windows a new look at a lower cost than a complete window replacement. A complete replacement of windows can be a costly and time-consuming task, especially for older homes. Repairing window sashes can be a great way to restore the original beauty of a home and value. Keeping a close eye on the condition of windows sashes is essential to avoid major problems. If you're not sure if your windows are in need of repair it's best to have them assessed by an expert. The cost of repairing a sash is often much cheaper than the cost to replace the entire window, and can reduce your energy bills as well. First, lower the upper sash down to the bottom. This is generally simple and will allow you to observe the "parting beads" which are a grooved part on the rails at the junction which keep the two sliding sashes separate. They can be removed using a blade that is attached to small pry-bars or a putty knife. They are usually nailed into place and painted, so be careful not to harm them or the sliding sash. Once you've removed the parting beads, the next job is to remove the pocket covers. These are pieces of wood inside the frame, lower down, which allow access to the sash weights. They are usually nailed in place - they could also be glued with paint so you need be cautious. After the nails have been removed you can move the sash up and down to ensure it moves smoothly. If not, there could be an issue with the counterweights and the sash cords. Once you've checked all of these, you can repair them as needed.
