Weather Stripping

Wooden window sashes are a great way to add a classic look to your home. They are also sturdy and will last for many years if they are properly maintained. They may, however, be damaged or degraded over time due to exposure or normal wear. Fortunately, sash repair specialists can restore your windows to their original condition and keep them looking great for much longer than newer replacement windows.

The first step in sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if it's worn out or loose. To fix it, begin by determining the brand of your window repair 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 that you can purchase replacement weather stripping that matches.

Then, take it off and place it on a surface to allow access to all four sides. If the sash is double-hung, take out the weights with their ropes that should fall into the pocket within the jamb lining. After you've removed the sash and the weights, use a utility knife to remove the weather stripping that was formerly in place at the corners, and then remove it 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 substitute for a scrap piece of lumber.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth it out using your putty knife, and then let it dry for a minimum of a day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will help protect the putty and give your sash an updated appearance.

Sash Hardware

The hardware that supports the window sashes can wear out over time and use. This could result in a door or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is typically relatively easy and affordable. If a sash becomes difficult to operate try spraying grease into the jamb channel then slide it open to see if that resolves the issue. If the issue continues it's most likely to be due to the sash's balance. It is necessary to remove the window sash in order to access the hardware.

Ideally, window sashes must be able to open and close with minimal effort however, this can be a difficult task when the weights are worn or if the sash that joins rail isn't properly glazed. This problem can be caused by a variety of things, such as the lack of maintenance or an incorrect weight rating for the particular window sash.

If the hinge arms on windows begin to slide, this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash was fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Old windows, particularly those in older homes, may be difficult to open and close, due to sagging hinges and a general lack of energy efficiency. In most instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner money on energy costs.

In order to make these sash repairs it is important to have all of the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will allow you to put the channel in the proper location after you've completed. Then, remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains which hold it in place. Soften any putty that has been hardened with the help of a heat gun set at medium and fitted with a nozzle shield. Take off the old sash and place it in a bag that is labeled.

Sash Weights

If your window sash repairs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out sash weights will improve sash operation and reduce the energy cost. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and connected to the movable the sash with rope. They function as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. The sash-weights are typically neglected or window repair ignored by homeowners and then turned into scrap when they fail; therefore, you may need to find replacements.

A weight in a sash that has fallen out of the cavity is difficult to get back It is therefore important to find a replacement that is suitable for the. You will also require a new piece string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that keep the components together can be removed with a pin punch and hammer. The majority of these pegs are large on one side and smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century used glue instead of pegs and can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised area loose with a mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inner workings.

After the sash has been stopped and the access panel has been removed, you are able to remove the old weight and replace it. Make sure you weigh the sash before you begin, as the old weights could be a different size than the one you need. Once the new weight has been installed, thread the string through the sash pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches of space at the head of the string for future adjustments.

Sash Cords

In most old double-hung window the chain or cord is affixed to the weights. This helps keep the sashes within the jamb in a balanced manner. Over time, these chains can become damaged and render it impossible to raise the windows. A new sash cable can restore 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 locate and remove the access panels within the jambs. They are typically screwed or nailed into and require removal. It may be possible to remove them with an axe or hammer, but it is always better to lay out dust sheets prior to beginning any work.

Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using flat bar or chisel. It is important to take your time as they're often wedged or nailed in place. If the sash remains in place, break the mortise-and-tenon joints out with a screwdriver or hammer, then remove each wood peg. The sash should be able move freely, however it may need some lubrication in order to feel less stiff.

Measure the length of sash cord/chain needed to reach the sash slot on the bottom, and the pulley on the top of the jamb. Cut the chain or cord and secure it in the previous step. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.

If you don't have a kit that replaces the old counterbalance system, it is recommended to keep the original weights for balancing in place. It's not expensive to buy them from a salvage store and they will be easy to install once you've got the sash opened. Based on the size and shape of your upvc window repairs, you might need to install one or two sashweights in order to keep it open.
