If your sash has been double glazed window repairs near me-hung, remove the weights using their ropes that should be buried in the jamb lining. Once you've removed the sash, use a utility knife to cut off the weather stripping from the corners. Then, remove it manually or with a putty knife.

After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear from time and usage, and the result can be a window or door that isn't able to open or close easily.

The ideal situation is for window sashes to swing open and closed without effort, but this is a difficult task when the weights wear out or if the sash's meeting rail isn't properly glazed. This problem can be caused by a variety of reasons, such as insufficient maintenance or an incorrect weight rating for the specific sash.

If the hinges on a window begin to sag this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To fix this issue, first make sure the sash is firmly seated in the opening of the frame and then remove it from the window. If the sash has been fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, windows that are old particularly those in older houses, could be difficult to open and close. In most instances, a few easy repairs can transform these windows into smooth operation and save homeowners money on energy bills.

In order to make these repairs to sash, it's important to have all of the necessary tools in place before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will allow you to get the channel back on place correctly when you're finished.

Sash Weights

If your window sash repairs are to replace a damaged cord or just to keep the windows functional by replacing worn out sash weights will improve sash operation and reduce energy costs. 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. These weights function as counterbalances and allow you to open and shut the window repair without requiring mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.

It's not easy to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights the sash cord.

Older wood windows are joined with mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs holding the components together. The majority of these pegs have a large diameter on one side and a smaller size on the other, so it is crucial to take out 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 has been removed then you can take out the sash stop and access the weight pocket. 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 interior workings.

When the sash has been shut off and the access panel has been removed, you are able to remove the weight you used and replace it. Make sure you weigh the sash prior to you do this, since the weights that were previously used may be different sizes 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 attach the string to the frame, but only leave a few inches of string hanging from the head for future adjustment.

Sash Cords

It's important to take your time as they're often stuck or nailed to the floor. If the sash remains in place, break the mortise and tenon joints using the help of a hammer and pin or screwdriver, then remove the wood pegs that are on each piece. You should now be able to move the sash back and forth freely, though it may require oiling if it seems stiff.

With the sash open, measure enough sash cord/chain to reach from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then fix it using the step 6 above. You can employ a hammer and screws or nails, but nails are less likely to cause damage.
