Window Sash Repairs

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

The sash is an inside frame that is able to move vertically up and down in windows that are open. This article will teach you how to make several simple repairs to sash.

Weather Stripping

Wood window sashes add a classic aesthetic to your home and, when properly maintained, they can last for a long time. They may, however, be damaged or degraded over time due to exposure or normal wear and tear. Thankfully, sash repair door experts can restore your windows to their original condition and keep them looking great for much longer than newer replacement windows.

Weather stripping is the first thing to address when repairing sash windows. It's on both the frame and the sash. It could cause drafts if worn out or loose. Begin by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corner or the aluminum spacers between panes). Remove the sash and mark its size and width so that you can find a replacement weather stripping that matches.

Then, remove the sash and place it on a work surface to allow access to all four sides. If your sash has a double-hung, you'll have to remove the weights and the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. After you've removed the sash and the weights, use a utility knife to cut off the weather stripping from the corners. Then, take it off by hand or using a putty knife.

After the sash is cleared, you can install the stoppers that separate the two sashes. These are long pieces that divide the sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you can also replace them with scrap wood.

After removing the parting stops and trimming them to your desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for at least a day. After the putty has completely cured, you can apply a topcoat of acrylic latex. This will help protect the putty and give your sash an updated 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 window or door repairman that can't be opened or closed easily. It's good to know that replacing or fixing this hardware is usually easy and affordable. If a sash isn't easy to operate try spraying lubrication into the jamb channel, and then open it to see if this resolves the issue. If not, the issue is most likely due to the sash balance, and you'll need to take out the sash in order to access this hardware.

Sashes for windows should be able to open and close without much effort. However, this can be a challenge if the weights have been worn out or the sash-to-rail meeting rail is not properly glazed. This issue could be caused by a variety of reasons, such as lack of maintenance or by a mismatched weight rating for the specific window sash.

If the hinge arms on a window begin to sag this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To address this problem, first ensure that the sash fits squarely in the opening of the frame and then remove it from the window repair near me. If the sash has been screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Because of sagging hinges and a general lack of energy efficiency, older windows, especially those in older homes, may be difficult to open or close. In many instances, a few easy repairs can turn these windows into smooth operation for the first time and save the homeowner cash on energy costs.

To complete these sash repairs it is essential to have all the tools needed before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to put the channel in the proper location after you've completed. Then, remove the sash and remove the hardware including the parting beads (Photo 2) and the cords or chains that secure it. Soften any hardened putty using a heat gun set to medium and fitted with a shield to block the nozzle. Remove the old sash, and keep it in a bag with a label.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to keep your windows functioning, replacing worn out weights on sash can improve sash operation and cut down on energy consumption. Sash weights are composed of heavy iron or lead cylinders that are encased inside a concealed cavity, and attached by ropes to the movable window sash. These weights provide counterbalance, allowing the window to be closed and opened without using mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they fail. Consequently you might need to search for replacements.

A sash weight that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits properly. You will also require an additional piece of string, a length of sash cord, and a few sash pulleys to tie the new sash weights to the sash cord.

Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the parts together. The majority of them are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated with a knife and a mallet.

Once the sash is freed then you can take out 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 then covered by an access panel made of wood that can be cut off to let you see the inner workings of the frame.

After the sash has been stopped and the access panel is removed, you are able to remove the weight that was previously installed and replace it. Make sure you weigh the sash prior to you do this, as the old weights may be different in size from what is needed. Once the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, you can nail the string to the boxed frame, leaving a few inches of string protruding from the head for future adjustment.

Sash Cords

The majority of double-hung windows with a history have a cord or chain attached to the weights which supports and keeps the sashes balanced within the jamb. Over time these cords can break, making it difficult to raise the window. A new sash cable will give you the ability to move and lower the sash, and keep it in position when it is opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. They are usually installed by screws or nails and must be removed or relocated. It may be possible to remove them using a hammer or chisel, however, it is best to lay out dust sheets before starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Use a flat bar or chisel to pry the tiny parting beads out of their grooves. It's important to take your time because they are usually placed in a wedge or nail. If the sash remains in place, pull the mortise and tenon joints free using a hammer or screwdriver and then remove each wood peg. You should now be able to move the sash around without difficulty, though it will probably need some oil if it feels stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord or chain, and then secure it in the previous step. You can employ a hammer, screws or nails, however nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system, it's recommended to keep the original weights for balancing in place. They are not expensive and are easy to install if purchased them from architectural salvage stores. Depending on the size and shape of your window you might need to install one or two sashweights to keep it open.
