Window sashes must be regularly checked for mold, mildew, and damage. By catching these problems early, you can save money on repairs in the future.

Weather Stripping

Wooden window Repair sashes can add an elegant look to your home. They are also durable and will last for many years provided they are properly maintained. However, they can be damaged or deteriorate in time due to exposure to elements and wear and tear. Sash repair experts can restore windows to their original condition and maintain their appearance much longer than replacement windows.

The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It could cause drafts if worn out or loose. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its width and height so you can get new weather stripping that is compatible with the original.

Then, take it off and place it on a surface so that you can reach all four sides. If the sash is double-hung, you'll also need to take off the weights and their accompanying ropes, which should have fallen into the intended pocket in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut off the weather stripping from the corners, then remove it by hand or window repair with a putty knife.

When the sash is clean it is time to replace the parting stops. These are long pieces that split the sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also replace them with scrap wood.

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 using your putty tool and let it dry for at least one day. After it has fully dried then apply a top coat of acrylic latex paint. This will help protect the putty, and give your sash a modern look.

Sash Hardware

The hardware that supports window sashes may wear out with time and use. This could result in a door repair or a window that is difficult to open or close. It's important to know that replacing and repair of this hardware is typically straightforward and cost-effective. If you're having difficulty opening the sash, spray some grease into the jamb channel. Then slide the sash out to see if that fixes the problem. If not, the problem is likely with the balance of the sash and you'll need to take out the sash to access the hardware.

Ideally, window sashes should swing open and closed with minimal effort but this is an issue if the weights become worn or if the sash that joins rail isn't properly glazed. This issue could be caused by a number of reasons, such as lack of maintenance or by a mismatched weight rating for the specific window sash.

If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to drag and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash was fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Due to sagging hinges, and a general deficiency in energy efficiency, windows that are old especially in older houses, could be difficult to open or close. In many instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner money on energy bills.

In order to make these sash repairs it is important to have all the tools needed before you begin. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will help you get the channel back on position correctly after you've completed. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. Heat gun with nozzle shield and medium setting will soften any putty that has been hardened. Remove the old sash and keep it in a bag labeled.

Sash Weights

If your window sash repairs are to replace a broken cord or just to ensure that the windows are functional and functional, replacing worn-out weights for sash will improve its operation and cut down on energy consumption. Sash weights are heavy, lead or iron cylinders that are enclosed inside a hidden compartment and attached to the movable sash by a rope. They function as counterbalances, which allows you to open and close the window without requiring mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners, and are turned into scrap when they fail; therefore you may have to locate replacements.

It is difficult to recover the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also need a new piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights onto the sash cord.

Mortise and Tenon joints can be used to join old wood windows. The wood pegs holding the components together can be removed using pin punches and hammers. The majority of these pegs have large diameters on one side and a smaller diameter on the other side, so it is essential to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be separated by using a knife and a mallet.

After the sash is removed, you can take off the sash stops and gain access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inner workings.

Once you have the sash stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Be sure to weigh the sash prior to you do this, as the old weights may be different sizes than the one you need. After the new weight has been installed, thread a string through the sash pulling mechanism. Then attach the string to the boxed frame, but only leave a few inches of string sticking out from the head for future adjustments.

Sash Cords

Most old double-hung windows come with a chain or cord attached to the weights which supports and keeps the sashes balanced in the jamb. Over time, these chains can become damaged and make it difficult to raise windows. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its place when it is opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are typically fixed or screwed in and must be removed or relocated. It is possible to remove them with the hammer or chisel however, it is best to lay out dust sheets before starting any work.

After removing the access panel, you are able to begin to work on the sash. Utilize a flat bar or chisel, to pry the narrow parting beads out of their grooves. It is essential to be patient because they are usually placed in a wedge or nail. If the sash is still in place, pry the mortise-and-tenon joints out with a screwdriver or hammer, then remove each wood peg. The sash should be able move freely now, but it may need some lubrication in order to feel less stiff.

Take a measurement of the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord or chain, and then fix it using the previous step. You can use either nail, hammer or screws. However, nails are less likely than screws to cause damage.

It is recommended to keep the original weights in place unless you have purchased a kit that will replace the counterbalance that was previously installed. It's cheap to purchase these from salvage shops for architectural purposes and they'll be simple to install once you've got the sash open.
