The sash is an interior frame that can move upwards and downwards in windows that open. This article will show you how to carry out a few simple sash repair.
Weather Stripping
Wood window sashes add a classic aesthetic to your home and, when properly maintained, they will last for years. However, they can become damaged or degrade as time passes because of exposure to the elements and normal wear and wear and tear. Fortunately, sash repair specialists can bring your windows back to their original condition and maintain their appearance for a longer period of time than replacement windows.
Weather stripping is the first aspect to consider when you are repairing sash windows. It's on both the frame and the sash. If it's worn or loose, out, it can cause drafts, as well as other issues. To fix it, begin by determining the brand of your window and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its size and width so that you can find a replacement weather stripping that matches.
Then, remove window repairs near me and place it on a surface to allow access to all four sides. If the sash is double-hung, take out the ropes and weights that should have fallen into the pocket within the jamb lining. After you have removed the sash using the utility knife, you can remove the weather stripping that was left by hand or using a putty blade.
After the sash has been cleared it is time to replace the parting stops. These are long pieces that separate the sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard. However, you can also replace them with scrap wood.
After removing the parting stop and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound with your putty tool, and let it dry for at least one day. When it's completely dried then apply a top coat of acrylic latex paint. This will help protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes susceptible to wear and tear from the wear and tear of use, and the result can be a window or door that won't open or close easily. It's important to know that replacing or fixing this hardware is usually straightforward and cost-effective. If you are having trouble opening a sash spray some oil into the jamb channel. Then, you can slide the sash open to see if this resolves the problem. If the issue continues it's most likely the sash balance. You will need to take off the window sash to access the hardware.
Ideally, window sashes should swing open and closed with very little effort, however, this can be a difficult task if the weights become worn or if the sash's meeting rail isn't properly coated. This issue can be caused by a number of factors, including insufficient maintenance or an incorrect weight rating for the specific sash.
If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to drag and eventually strike the frame in the corner in the opposite direction of the hinge arm (Photo 1). To remedy the issue, make sure that the sash is centered in the frame opening, and then take it off. If the sash has been fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Windows that are old, especially in older homes, can be difficult to close and open due to hinges that are sagging and an overall inefficiency. In most instances, a few easy repairs can turn these windows into smooth operation and save homeowners cash on energy costs.
To complete these sash repairs it is essential to have all of the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will assist you in getting the channel back in position correctly after you've completed. Take the sash off and take out all the hardware, including the parting beads, cords, and chains that hold the sash in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash and put it in a labeled bag.
Sash Weights
Sash weights can be replaced to improve the operation of your window sash, and also reduce energy costs. Sash weights consist of heavy lead or iron cylindricals that are contained in a concealed cavity and are connected via ropes to the movable window sash. These weights act as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and then turned into scrap when they fail; therefore, you may need to search for replacements.
A sash weight that has fallen out of the cavity is difficult to get back and you'll need to find a new one that fits properly. You will also require a new piece of string, a length sash cord and some sash pulleys that will tie the new sash weights onto the sash cord.
Mortise and Tenon joints can be used to join old wood windows. The wood pegs that keep the components together can be removed by the use of a pin punch and hammer. The majority of these pegs are large on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be cut by using a knife or mallet.
Once the sash has been removed, you can take off the sash stops and gain access to the weight pockets. Usually it is done by drilling an opening in the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.
Once you have the sash stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with the new. Be sure to weigh the sash prior to you begin, as the old weights could be a different size than what you require. After the new weight is installed, tie a string to it and thread it through the sash pulley. Then, nail the string to your boxed frame. Leave a few inches protruding at the head of the string to allow future adjustments.
Sash Cords
In most old double-hung window, a cord or chain is connected to the weights. This supports and keeps the sashes of the jamb level. As time passes, these cords may break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash up and down and keep it in position when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are usually screwed or nailed into and need to be removed. It may be possible to take them out using the hammer or chisel however, it is best to lay out dust sheets prior to beginning any work.
After you have removed the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using a chisel or flat bar. It is important to be patient because they are usually placed in a wedge or nail. If the sash is still in place, break the mortise and tenon joints with a hammer and pin punch or screwdriver, then remove the wood pegs on the components. The sash should move around freely now, however it may need some lubrication to feel less stiff.
With the sash in an open position, measure enough sash cord/chain to reach from the pulley at the top of the jamb to the sash slot on the bottom. Cut the chain or cord and fix it as described in Step 6 above. You can use nail, hammer or screws. However nails are less likely to cause damage.
If you haven't purchased a kit that replaces the old counterbalance system, it is recommended to keep the original weights for balancing in place. It's not expensive to buy these from salvage shops for architectural purposes and they'll be simple to install once you've got the sash unlocked. Depending on the dimensions and shape of your window, you may need to use one or two sashweights in order to keep it open.
