Weather Stripping
Wood window sashes add an elegant look to your home and, when properly maintained, they can last for years. However, they may become damaged or degraded as time passes because of exposure to the elements and wear and wear and tear. Sash repair experts can restore windows to their original state and keep them looking great longer than replacement windows.
The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if it's worn or loose. 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). Then, take the sash off and mark its height and width, so you can find new weather stripping that matches.
Then, remove the sash from the holder and place it on an even surface that allows you to see all four sides. If the sash is double-hung, you'll need to remove the weights and their ropes which should have slipped into the pocket that was intended to be in the jamb liner. Once you've removed the sash, use a utility knife to remove the old weather stripping at the corners. Then, remove it by hand or using a putty knife.
After the sash is cleaned, you can replace parting stops. These are long pieces of wood that divide the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could substitute a scrap piece of wood.
After removing the stoppers for parting and trimming them to your desired length and thickness, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty knife, and allow it to dry for at least a day. After it has fully dried then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that supports the window sashes can wear out with time and use. This can result in windows or doors that is difficult to open or close. The good news is that fixing and replacing this hardware is typically very simple and cost-effective. If a sash isn't easy to operate, try spraying some grease into the jamb channel then slide it open to see if it solves the issue. If the issue continues it's most likely that the sash balance is off. It is necessary to take off the window sash to access the hardware.
window repair sashes should be able to open and close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash meeting rail is not properly coated. This issue can be caused by a number of things, such as the lack of maintenance or an incorrect weight rating for a particular sash.
If the hinges on a window begin to sag this can cause the sash drag and eventually hit against the frame at the opposite corner (Photo 1). To resolve this problem, first ensure that the sash fits squarely in the opening of the frame and then take it out of the window. If the sash has been screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Due to hinges that are sagging, window repairs and a general deficiency in energy efficiency, old windows, especially those in older homes, may be difficult to open or close. In many instances, a few minor upvc door repairs near me can transform these windows into smooth operators and save homeowners cash on energy costs.
It is important to have the tools you require before you begin. Mark the hinge channel location on the frame (Photo 1) using pencil. This will help you get the channel back in place correctly when you're finished. Take the sash off and then remove all hardware, including the beads for parting cords, chains, and cords that keep the sash in place. Heat gun with nozzle shield and a medium setting can soften any hardened glue. Remove the old sash and put it in a labeled bag.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and help reduce the energy cost. Sash weights consist of iron or lead cylinders that are enclosed in a concealed cavity and attached by a rope to the movable window sash. These weights provide counterbalance, allowing the window to be closed and opened without using mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners and turned into scrap when they break; therefore, you may need to find replacements.
It is difficult to recover an sash-weight which has fallen from the cavity, so you'll need to find one that fits properly. You will also require a new piece of string, a length of sashcord and some sashpulleys to tie the new weights to the cord.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the components together. The majority of them are large on one side, and smaller on the other. It is important to first remove the smaller diameter sides. Sashes that were made later in the century utilized glue instead of pegs. They can be separated by cutting through the glue line using an instrument, and then tapping the mortised section loose with mallets.
Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. Usually it is done by drilling an opening at the bottom of each jamb. The hole is then covered with an access panel made of wood that can be ripped off to let you view the inside of the frame.
After the sash has been stopped and the access panel has been removed, you can take off the weight you used and replace it. Make sure you weigh the sash before you begin, as the old weights may be different sizes than the one you need. After the new weight has been installed, you can thread the string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches at the head of the string to allow future adjustments.
Sash Cords
The majority of double-hung windows with a history include a chain or cord attached to the weights which keeps the sashes balanced in the jamb. Over time, these cords can get damaged and make it impossible to raise the windows. A new sash cord will restore the ability to move the sash upwards and downwards and keep it in place when opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are usually installed by screws or nails and will require to be removed or moved. You could employ a hammer and chisel to prise them off however, it is always best to lay down dust sheets prior to starting any work.
After removing the access panel, you can begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with a chisel or flat bar. They are typically wedged into or nailed, but they can be removed and it's worth your time. If the sash is still in place, pry the mortise-and-tenon joints out using a hammer or screwdriver and then remove each wood peg. The sash should move around freely now, however it may need some lubrication in order to feel less stiff.
Determine the length of sash chain/sash cord required to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the cord/chain, and then fix it using Step 6 above. You can either employ a hammer, nail or screws, but nails are less likely to cause damage.
If you don't have an item that replaces the counterbalance system that was in place before, it's recommended to keep the original weights for balancing in place. They're not expensive and simple to install if you purchase them from architectural salvage stores. Depending on the size and shape of your window you may require one or two sashweights to keep it open.
