The sash is an interior frame that moves vertically up and down in windows that are open. This article will show you how to do simple sash repairs.
Weather Stripping
Wooden window sashes can add a classic look to your home. They are also sturdy and will last for many years when they are maintained properly. They can, however, become damaged or degraded with time, due to exposure and normal wear and tear. Sash repair experts can restore windows to their original condition and keep them looking great longer than replacement windows.
The first step for sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. If it's worn or loose, out, it can cause drafts, as well as other issues. To fix it, begin by determining your window repair (you can find out more)'s brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off, and mark its size and width so that you can get replacement weather stripping that matches.
Then, you can remove the sash from its holder and place it on an even surface that allows you to reach all four sides. If your sash is double-hung, you'll also need to remove the weights as well as their ropes which should have slipped into the pocket that was intended to be in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut off the old weather stripping at the corners. Then, take it off by hand or using a putty blade.
Once the sash has been cleared, you can install the parting stops. These are long pieces that divide the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also substitute for a scrap piece of lumber.
After removing the parting stop and cutting it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth the compound with your putty knife and let it dry for a minimum of a day. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports window sashes susceptible to wear and tear due to age and use and the result could be a door or window that isn't able to open or close easily. The good thing is that fixing and replacing this hardware is usually relatively easy and affordable. If a sash isn't easy to operate you can try spraying some lubrication into the jamb channel then open it to see if it solves the issue. If not, the problem is likely with the sash balance and you'll need to take out the sash to gain access to the hardware.
Ideally, window sashes must move open and shut with minimal effort but this is a difficult task when the weights wear out or if the sash's meeting rail isn't properly coated. This problem can be caused by a number of things, such as insufficient maintenance or an incorrect weight rating for the particular sash.
If the hinge arms on the upvc window repair begin to move, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash fits squarely in the frame's opening and then remove it from the window. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Due to sagging hinges, and a general deficiency in energy efficiency, old windows particularly those in older houses, could be difficult to open and close. In many cases, a few simple repairs can transform these windows into smooth operation and save homeowners money on energy costs.
To make these sash repairs it is essential to have all of the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to place the channel in the right position after you've finished. Remove the sash and then remove all hardware including the parting beads cords, chains, and cords that help to hold the sash. Soften any hardened putty with a heat gun set to medium and fitted with an shield for the nozzle. Take off the old sash and store it in a bag with a label.
Sash Weights
If your window sash repairs are to replace a broken cord or to keep your windows functioning by replacing worn out sash weights will improve sash operation and help reduce the energy cost. Sash weights are heavy lead or iron cylinders, which are enclosed inside a hidden compartment and connected to the movable sash by a rope. These weights function as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. When they fail, sashweights are usually neglected or not used by homeowners.
A weight from a sash that fell out of the cavity is difficult to recover It is therefore important to find a replacement that fits properly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights to the sash cord.
Older windows made of wood are joined with mortise and tenon joints. Pin punch and hammer can be used to cut off the wood pegs that hold the components together. Most of these pegs have a large diameter on one side and a smaller diameter on the other, which is why it is important to remove the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be separated by using a knife and mallets.
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 done through an opening at the bottom of each jamb. This hole is covered by an access panel of wood that can be cut off so that you can observe the inner workings of the frame.
After the sash has been stopped and the access panel has been removed, you can take off the weight that was previously installed and replace it. Make sure you weigh the sash prior to you do this, as the old weights could be a different size than what is needed. After the new weight is in place, tie a string to it and thread it through the sash pulley. Then, you can attach the string to your boxed frame. Leave a few inches of space at the end of the string for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord attached to the weights that keeps the sashes level 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 attached by nails or screws and need to be removed. You might be able to use a hammer or chisel to prise them off however, it is always best to lay down dust sheets prior to commencing any work.
Once the access panel is removed, you can begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. It's important to take your time because they are usually wedged or nailed in place. If the sash remains in place, break the mortise-and-tenon joints out with a hammer or screwdriver, then remove each wood peg. The sash should move around freely now, however it might require some lubrication to make it feel less 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 chain or cord and attach it as described in Step 6 above. You can use nail, hammer or screws. However, nails are less likely than screws to cause damage.
If you haven't purchased an upgrade kit to replace the old counterbalance system, it is recommended to keep the original weights for balancing in place. It's cheap to purchase them from architectural salvage stores and they'll be simple to install once you have the sash opened. Based on the dimensions and shape of your window you might need to install one or two sashweights to keep it open.
