Weather Stripping
Wood window sashes provide an elegant look to your home and, when properly maintained, can last for many years. However, they can be damaged or degraded over time due to exposure and normal wear. Fortunately, sash repair specialists can bring your windows back to their original condition and keep them looking great for a longer period of time than replacement windows.
Weather stripping is the most important aspect to consider when you are repairing windows with sash. It's located on both the frame and sash. It could cause drafts if worn or loose. To fix it, start by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width to find the appropriate weather stripping replacement to match.
Then, remove the sash and set it on a surface to allow access to all four sides. If the sash is 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, you can remove the weather stripping that was left by hand or with the putty blade.
Once the sash is clear, you can replace the parting stops. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can substitute for a scrap piece of lumber.
After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth it out using your putty knife, then let it dry for at least a few days. When the putty is fully dried, you can apply a topcoat of acrylic. This will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports the windows sashes can become worn out over time and with use. This could lead to the window or door that is difficult to open or close. It's good to know that replacing and fixing this hardware is usually simple and inexpensive. If you're having trouble opening a sash, spray some grease into the jamb channel. Then, you can slide the sash up and open to see if it resolves the issue. If not, the issue is likely with the sash balance, and you'll have to take off the sash in order to access the hardware.
Window sashes need to be able to open and close with minimal effort. However, this may be difficult if weights are worn out or the sash-to rail meeting rail is not properly glazed. This can be due to a variety of factors such as the lack of maintenance or an unmatched weight rating.
If the hinges on the window begin to move, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To address this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash is secured 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, and a general lack of energy efficiency, windows that are old especially in older homes, may be difficult to open and close. In many instances, a few minor repairs can turn these windows into smooth operation for the first time and save the homeowner money on energy costs.
In order to make these repairs to the sash it is important to have all the necessary tools lined up before you begin. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will allow you to place the channel in the right position after you've finished. Then, remove the sash and remove the hardware, including the parting beads (Photo 2) and the cords or chains which hold it in place. The nozzle shield of the heat gun and a medium setting can soften any hardened putty. Take off the old sash and put it in a bag that is labeled.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or simply to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and reduce energy costs. Sash weights consist of heavy iron or lead cylindricals that are contained in a hidden cavity and connected by ropes to the moveable window sash. These weights act as counterbalances, which allows you to open and shut the window without the need for mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners and then turned into scrap when they break; therefore you might need to locate replacements.
It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that is suitable for the. You will also require a new piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord.
Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs holding the parts together. The majority of these pegs are big on one side, and smaller on the other. It is important to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated with a knife and mallet.
After the sash is removed then you can take out the stopper on the sash and get access to the weight pocket. This is usually done through tiny holes in the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the interior workings.
Once window repairs near me is stopped and the access panel has been removed, you are able to remove the old weight and replace it. First, weigh the sash, as the weights you've got may not be of the right size. After the new weight is installed then tie a string to it and thread it through the pulley of the sash. Then nail the string to the frame, but leave a few inches of string protruding from the head for future adjustment.
Sash Cords
In most old double-hung window, a chain or cord is affixed to the weights. This helps keep the sashes in the jamb level. As time passes, these cords can get damaged and render it impossible to raise the windows. A new sash cable will restore the ability to move and lower the sash, and keep it in place when it is opened.
The first step to replace sash cords is to locate and take out the access panels located in the jambs. They are usually fixed or screwed in and will require to be removed or relocated. It is possible to remove them using an axe or hammer, but it is always better to lay out dust sheets prior to starting any work.
After the access panel has been removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. They are usually wedged in or nailed, but they can be snipped out which is why it's worth your time. If the sash is still in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, and then take out the wood pegs attached to the components. The sash should be able move freely now, but it might require some lubrication in order to feel less stiff.
Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom of the pulley located at the top of the jamb. Cut the cord/chain and then secure it as in the previous step. You can either employ a hammer, nail or screws, but nails are less likely to cause damage.
If you don't have a kit that replaces the counterbalance system that was in place before, it's best to keep the original balancing weights in place. They're not costly and easy to install if you buy them at architectural salvage stores. Based on the size and shape of your window, you might need to install one or two sashweights to keep the sash open.
