Sash Window Repair
Sash windows add a touch of elegance to any home. They can become drafty and problematic as they get older. Sash window repairs can be a great option for making them more functional and preserving the original elegance.
The first step in sash window repair is to take off the "pocket covers". These are small pieces of wood that are located low on the frame and let the weights in.
Sashes that have been damaged
If your windows' sash are damaged or leaky, you'll need to do more than just patch the surface. Doing a thorough repair can save you money in the long run, particularly if you have a older home with poor insulation. Here are some common problems with sash windows and the best way to fix them:
Problems with Sticking
It is difficult to close or open the window when the sash doesn't fit properly into the frame. This could cause a rattling sound and allow drafts into your home.
To fix this, use an utility knife to cut and then cut away the paint line on the interior side of your sash. Be careful not damage the wood. Then, you'll want to apply a sash grease that will allow it to move more smoothly.
Broken Sash Cords
In certain instances, the old double-hung sashes are made of metal or cotton cords to support the weights used to raise and lower the sashes. Over time, these cords could break and make it difficult to lift the sash and keep it up. Follow these steps to fix the problem:
Remove the frame sash and pull it to the right until it is completely open. Pull the cord from the bottom of the sash. Cut it and take out any nails that are protruding from the end. Utilizing needle-nosed pliers remove the nail and then insert it into the side channel. The knot of the cord should be tucked into the hole, and secure it using a nail set.
Re-install the sash and install the beads for staff. Make sure new sash windows leave enough slack in the cords for optimal operation. Install the counterweights and balances. To reduce draughts, a small amount of decorators caulk may be placed between the bead of the staff and the box.
When the frame and sash are fully repaired, bed them in glazing putty. Glazing putty is made using chalk and linseed. Mix in enough chalk to make it workable and not stick to your hands. Let the putty dry completely before installing the sash again and painting the frame.
Broken sash cords
Old double-hung (two sashes) windows use cotton cords or metal chains attached to the counterweights to support and keep the sashes level within the window jamb. As time passes, the cords could break, which stops the sashes from opening and closing, making it difficult to lower or raise the window. The sash cords can be replaced in less than a few hours.
Remove the staff bead which separates the upper from lower sashes. You can remove the bead by using needle-nose pliers. A nail is inserted through the knot and into the sash's casing to hold it in place. Remove any rusty nails from the stop beads and clean off caulk, paint, and old cord traces around the groove in the sash.
To open the window, pull on one of the cords that runs through the sash to lift it up. When you've pulled the cord to the maximum extent it can go make a mark on the cord using pencil, and then cut it to length using a utility knife. When you finish making sure that the new cord matches with the groove in the sash and is tied to the frame of the sash by a knot.
If the sash is still too high to move it, you can use sharp side cutters to cut off and remove the old cords. After the sash is freed, you will have to remove the access panels in the sash channels in order to expose the counterweights and pulley system. If the window has been painted, you'll have to cut the seams using either a hammer or chisel, in order to remove the panel without damaging it.
Once you've removed your access panel, you'll see the two sash weights made of cast iron in each pocket. Take the one on the back and the other on the front, then tie each sash cord to a weight with a self-tightening knot. After you've tied the new cords, reconnect the sashweights and reset the system to function properly.
Drafts
Sash windows are a fantastic way to add some old-fashioned charm to homes. However, they can be difficult to maintain. They can be difficult to open or close and rattle in the wind, and let drafts in. These problems are usually caused by the swelling of wood or paint buildup, or sash cords that have rotted. There are several easy and cost-effective methods to correct these issues and keep your sash window working correctly.
Disassembling an old sash is the initial step in repairing it. Remove the sash, as well as the frame, and ensure whether all parts are in good condition. Next, sand down the wood to enhance its appearance and prevent drafts. A small amount of silicone spray or wax can make the sash slide more easily. If the sash remains stuck using a utility knife, you can use it to cut any paint layers. A new set of tilt pins can enhance the window's performance.
Weights are pushed across pulleys in order to balance the weight of windows with sash. These weights, which are typically constructed of cast iron, can be accessed through an access panel or pocket within the lining of the box. A dividing strip is put inside the window frame to prevent the weights from colliding.
Accessing these weights can be tricky, as the upper sash is sealed and is nailed into place. If you're diligent and cautious, you can pull the sash out with a pair of bar clamps that are spread apart. It could take a little few tapping and jiggling to get it free, but once you have removed it, make sure to inspect the sash cord and replace it with new rope (not cotton) If you need to.
While you're at the same time, you could also replace the balance of the sash to make the window easier to open and close. It's a lot easier than you think to replace the double-hung balance on a window. You can do it yourself if have the right tools and a replacement kit.
Rotten sill
Over time, old timbers deteriorate and even the best-maintained sash windows will start to show signs of decay. If the rot is only limited to the sill, it might be possible to restore the window. If the rot has spread through the frame and into the interior and has damaged structural parts, it may be time to replace the window.
It is essential to replace a rotten window sill before it causes more damage to the window. The first step is to remove the sill plates and studs. You may have to install temporary support in the event that the studs bear weight. After taking the old sill off and washing off any paint remaining from the sill plate. After cleaning the sill, replace it with the new one and then nail it into the studs.
A sill that is rotten can be unsightly and lead to future costly repairs. For example, it can cause the sash to move and can be difficult to notice and can lead to cracks or broken glass pane. A rotten sill can allow water to enter the wall and cause mold.
Replacing a rotten sill is not as hard as it might sound. It is essential to keep the window well-maintained to prevent rot, so you should clean regularly the windows' tracks and sashes to keep them clear of dirt and other debris. Apply a protective seal on the frames of your windows to keep them dry. You can also utilize a humidifier to regulate the moisture in your home. This will prevent wooden sashes sticking or swelling.
Sticky sashes are a frequent issue for windows with sash. To get them out of the way it is possible to apply small amounts of silicone spray or wax onto the window tracks to enable them to slide easily. If the sashes are stuck due to the buildup of paint, you can use an utility knife to slice through the paint layers and remove the sashes.
Another option to resolve a sticking sash is to replace the parting bead. If the sash is still stuck it is possible to try to draught proof it. This involves putting strips of rubber in the gaps between the sash and frame, which reduces airflow and improves the acoustic performance of the window.
