The sash is an internal frame that is able to move upwards and downwards in windows that open. This article will teach you how to do a variety of simple repairs to sash.
Weather Stripping
Wooden window sashes can add a classic look to your home. They are also durable and can last many years if they are properly maintained. However, they may become damaged or degrade as time passes due to exposure to the elements and wear and tear. Sash repair specialists can restore windows to their original state and keep them looking great longer than replacement windows.
The first step in sash window repairs (privatehd.org) is addressing weather stripping, which is found on both the sash as well as the frame. It could cause drafts if worn or loose. Begin by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Take the sash off and mark its width and height so you can purchase replacement weather stripping that matches.
Next, remove the sash and place it on a surface so you can access all four sides. If your sash has been double-hung, take out the weights with their ropes that should be buried in the jamb lining. Once you've removed the sash, use a utility knife to cut away the weather stripping that was formerly in place at the corners, and then take it off by hand or using a putty blade.
Once the sash is clear and clean, you can put in the parting stops. These are long pieces that divide the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. But, you can also use with a scrap piece of wood.
After removing the stoppers for parting and trimming them to the desired length and thickness, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using your putty tool and allow it to dry for at least one day. When the putty is fully cure and dried, you can apply a topcoat of acrylic. This will protect the putty, and give your sash an updated look.
Sash Hardware
The hardware that holds the window sashes may wear out over time and use. This could result in a door or a window that is difficult to open or close. It's good to know that replacing or repair of this hardware is typically straightforward and cost-effective. If you're having trouble opening the sash, spray some grease into the jamb channel. Then slide the sash out to see if this resolves the problem. If not, the issue is most likely due to the balance of the sash and you'll need to take out the sash in order to access the hardware.
The ideal situation is for window sashes to move open and shut without effort, however, this can be difficult when the weights wear out or if the sash meeting rail isn't properly glazed. This problem can be caused by a variety of factors, including lack of maintenance or by the wrong weight rating for a particular sash.
If the hinge arms on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To fix the problem ensure that the sash is centered in the frame opening, and then take it off. If the sash has been screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).
Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows particularly those in older homes, can be difficult to open or close. In most instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner cash on energy costs.
It is essential to have the tools you need before you start. Start by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will allow you to put the channel in the correct position after you've finished. Remove the sash and take off the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. Soften any hardened putty with a heat gun set to medium and fitted with an nozzle shield. Take off the old sash and store it in a labeled bag.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or to keep the windows functional by replacing worn out sash weights will improve sash operation and help reduce the energy cost. Sash weights are made of iron or lead cylinders that are encased in a hidden cavity and connected by ropes to the movable window sash. They provide counterbalance that allows the window to be shut and opened without using mechanical or electrical devices. If they fail, sashweights tend to be ignored or disabled by homeowners.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also need an additional piece of string, a length sash cord and some sash pulleys to tie the new sash weights onto the sash cord.
Mortise and Tenon joints are used to join old wood windows. The wood pegs that keep the parts together can be removed by the use of a pin punch and hammer. Most of them have an enormous diameter on one side and a smaller size on the other, so it is important to remove the smaller-diameter sides first. Later sashes used glue instead of pins. They can be separated by using a knife or a mallet.
After the sash is removed, you can take off the sash stops and access the weight pockets. This is typically done by drilling a small hole at the bottom of every jamb. This hole is then covered by an access panel of wood that can be ripped off to allow you to observe the inner workings of the frame.
After the sash has been stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with the new. Be sure to weigh the sash before you do this, as the old weights may be a different size than what is needed. Once the new weight is installed then tie a string to it and then thread it through the pulley for the sash. Then, nail the string to your boxed frame. Leave a few inches at the top of the string to allow future adjustments.
Sash Cords
The majority of double glazed window repairs-hung windows with a history include a chain or cord attached to the weights which supports and keeps the sashes in balance within the jamb. Over time, these cords can become damaged and make it impossible to raise windows. A new sash cable will give you the ability to move and lower the sash and ensure it stays in place when opened.
The first step in replacing sash cords is to locate and remove the access panels within the jambs. They are typically screwed or nailed into and require removal. You could employ a hammer and chisel to remove them however, it is always best to lay down dust sheets prior to starting any work.
After the access panel has been removed, you can start working on the sash. Utilize a flat bar or chisel, to pry the narrow parting beads from their grooves. It is essential to take your time as they're often wedged or nailed in place. If the sash remains in place, pull the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. You should be able to move the sash around without difficulty, though it will probably need some oiling if it seems stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then attach it as described in Step 6 above. You can do this with nail, hammer or screws. However nails are less likely than screws to cause damage.
If you don't have an item that replaces the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. It's not too expensive to purchase them from architectural salvage stores and they will be easy to install once you've got the sash open. Based on the size and shape of your window you may require one or two sashweights to keep the sash open.
