Weather Stripping
Wood window sashes give a classic aesthetic to your home and, when properly maintained, can last for a long time. They can, however, become damaged or degraded with time, due to exposure and normal wear and tear. Sash repair specialists can restore windows back to their original condition and maintain their appearance much longer than replacement windows.
Weather stripping is the first issue to take care of when fixing windows that have sash. It's on both the frame and sash. It could cause drafts if worn out or loose. Start by identifying the window's brand and the date of manufacture for the glass (etched on the corner of the glass or the aluminum spacers between panes). Take the sash off, and mark its width and height so you can purchase new weather stripping that is compatible with the original.
Then, take the sash from the holder and place it on an even surface that allows you to reach all four sides. If the sash is double glazing repair-hung, you'll have to remove the weights and their accompanying ropes, which should have fallen into the pocket of the jamb liner. After removing the sash with the utility knife, you can remove the weather stripping from the old sash by hand or using a putty knife.
When the sash is clean it is time to replace the parting stops. These are long pieces that divide the sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use scrap wood.
After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for a minimum of a day. After it has fully dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes may wear out over time and with use. This can result in windows or doors repair that is difficult to open or close. The good thing is that fixing and replacing this hardware is usually quite simple and inexpensive. If a sash isn't easy to operate, try spraying some lubrication into the jamb channel and then open it to see if it solves the issue. If the issue continues it's most likely to be due to the sash's balance. You will need to remove the window sash in order to get access to this part of the hardware.
Window sashes should open and close with little effort. However, this could be difficult if weights are worn out or the sash-to-rail connecting rail isn't covered with. This issue can be caused by a number of things, such as the lack of maintenance or the wrong weight rating for the specific sash.
If the hinge arms on a window begin to sag this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash fits squarely in the opening of the frame and then take it out of the window. If the sash is screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Because of sagging hinges and a general lack in energy efficiency, old windows particularly those in older homes, can be difficult to open or close. In many cases just a few easy fixes can make these windows operate smoothly once more and save homeowners money on energy bills.
In order to make these repairs to the sash, it's important to have all the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will help you get the channel back into position correctly after you've completed. Remove the sash and take out all the hardware, including the parting beads cords, chains, and cords that hold the sash in place. Soften any hardened putty using an electric heat gun set to medium and equipped with a shield for the nozzle. Remove the old sash, and store it in a bag with a label.
Sash Weights
Whether your window sash upvc door repairs are to replace a broken cord or just to keep your windows functioning and functional, replacing worn-out weights for sash will improve its operation and cut down on energy consumption. Sash weights consist of heavy iron or lead cylindricals that are contained in a hidden cavity and attached by ropes to the movable window sash. These weights act as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll need to find one that is suitable for the. You will also require a new piece string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.
Older windows made of wood are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs holding the parts together. Most of these pegs have an enormous diameter on one side and a smaller one on the other, so it is important to remove the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be cut with a knife and a mallet.
After the sash has been removed then you can take out the sash stop and access the weight pocket. This is usually done via an opening at the bottom of each jamb. This hole is then covered by a wooden access panel which can be removed to allow you to view the inside of the frame.
After you have the sash stopped and the access panel removed, you will be able to remove the old sash weight and replace it with new. Weigh the sash first to ensure that the weights you have might not be of the right size. After the new weight is installed you can tie a string around it and then thread it through the pulley of the sash. Then nail the string to the boxed frame, but leave a few inches of string hanging from the head to allow for future adjustments.
Sash Cords
Most old repairing double glazed windows-hung windows include a chain or cord attached to the weights that keeps the sashes in balance in the jamb. Over time, these chains can get damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its place when opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually screwed or nailed into and require removal. It is possible to take them out using a hammer or chisel, but it is always best to lay out dust sheets before starting any work.
After removing the access panel, you are able to begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using a chisel or flat bar. They are usually wedged in or nailed, but they can be prised free and it's worth your time. If the sash is still in place, break the mortise and tenon joints using pin punch and hammer or screwdriver, then remove the wood pegs on each piece. The sash should be able to move freely, 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 on the bottom, and the pulley on the top of the jamb. Cut the cord or chain and secure it in Step 6 above. You can use nail, hammer or screws. However, nails are less likely than screws to cause damage.
It's best to leave the weights that came with the original counterbalance unless you've purchased a kit that will replace the counterbalance that was previously installed. It's not too expensive to purchase these from salvage shops for architectural purposes and they'll be simple to install once you have the sash unlocked. Based on the dimensions and shape of your window you may require one or two sashweights in order to keep the sash open.
