Weather Stripping
Wood window sashes give an elegant look to your home. If properly maintained, can last for a long time. However, they can become damaged or degraded with time, due to exposure and normal wear. However, sash repair experts can bring your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.
The first step to sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if worn out or loose. Begin by identifying the window's brand and the manufacturer's date (etched on the glass's corners, or the aluminum spacers between panes). Then, remove the sash and mark its width and height, so you can find the appropriate weather stripping replacement to match.
Then, remove the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If your sash was double-hung, take out the weights using their ropes that should be buried in the jamb lining. After removing the sash with the utility knife, take off the weather stripping from the old sash by hand or with a putty blade.
After the sash has been cleaned, you can replace the parting stops. These are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.
After removing the parting stop and trimming 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 a day. After the putty has completely dried it is possible to apply a topcoat of acrylic. This will protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that supports the window sashes may wear out over time and with use. This could lead to the Window Repair or door that is difficult to open or close. The good news is that fixing and replacing this hardware is generally relatively easy and affordable. If you're having difficulty opening the sash, spray some grease into the jamb channel. Then, you can slide the sash up and Window Repair open to see if that fixes the issue. If the issue continues, it is most likely to be due to the sash's balance. It is necessary remove the window sash to access the hardware.
The ideal situation is for window sashes to swing open and closed without effort, however, this can be an issue if the weights become worn or if the sash that joins rail isn't properly coated. This issue could be caused by many factors such as the lack of maintenance or an unmatched weight rating.
If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to slide and eventually hit the frame in the corner directly opposite the hinge arm (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash was fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, old windows, especially those in older homes, can be difficult to open and close. In most instances, a few easy repairs can transform these windows into smooth operation again and save the homeowner money on energy bills.
To complete these sash repairs it is important to have all the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will assist you in getting the channel back into place correctly when you're finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any hardened putty with a heat gun set to medium and equipped with a nozzle shield. Remove the old sash and put it in a bag labeled.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or simply to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and reduce the energy cost. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and are connected via ropes to the movable window sash. They function as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. If they fail, sashweights are often ignored 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 fits correctly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights to the sash cord.
Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. The majority of these pegs are large on one side and smaller on the other. It is important to first remove the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line using a knife, then tapping the mortised area loose with a mallet.
After the sash is removed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inside workings.
When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Weigh the sash first to ensure that the weights you have might not be the correct size. Once the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches protruding at the head of the string to allow future adjustments.
Sash Cords
In the majority of old double glazing repairs-hung windows the chain or cord is affixed to the weights. This supports and keeps the sashes in the jamb in a balanced manner. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash up and down and keep it in place when it is opened.
The first step in replacing sash cords is to locate and take out the access panels located in the jambs. They are usually installed by screws or nails and must be removed or relocated. You may be able to employ a hammer and chisel to prise them off but it's best to lay down dust sheets before commencing any work.
After removing the access panel, you can begin working on the sash. Utilize a flat bar or chisel to pull the small parting beads from their grooves. They are typically wedged into or nailed but can be snipped out which is why it's worth your time. If the sash remains in place, pry out the mortise and the tenon joints by 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 require some lubrication in order to feel less stiff.
With the sash in an open position, measure enough sash cord/chain to reach from the pulley on the top of the jamb to the sash slot in the bottom. Cut the cord or chain and secure it as in the previous step. You can do this with a hammer, nails, or screws. However nails are less likely than screws to cause damage.
Unless you've bought an item that replaces the old counterbalance system, it's best to keep the original balancing weights in place. They are not expensive and easy to install if purchased them at architectural salvage stores. Depending on the dimensions and shape of your window, you may need to use one or two sashweights in order to keep the sash open.
