Window Sash Repairs

Many homeowners don't care about window sashes as long as they are closed, open, and keep outside air out and the inside air in. As time passes, window sashes can wear out and cause drafts, air leaks, or even sashes that are stuck.

Sash Weights

If your windows aren't opening and closing smoothly or are sluggish the way they should, a defective counterbalancing system could be the reason. This could be because of a broken or damaged chain/sash cord as well as a misaligned or unattached sash weight, or a broken pulley.

The sash weights are tiny boxes, typically made of cast iron, that serve to support the sash as well as balance the window's counter-weight system. They are located at the bottom of every window frame. They are covered with wood panels which can be removed to reveal their position. These panels can be removed to allow access to the sash-weight pockets in order to clean and repair or replace them.

If you've had sash windows for some time, you may have an issue with the sash weights, which cause them to lean or catch. The weights can be too heavy (they should be slightly heavier than top sash), or installed improperly.

To remedy this issue, remove the stops (the trim that runs along the inside of the window at the point where it joins with the frame to keep it in place). Put them away. This requires you to be careful so as to not scratch the shape of your meeting rails. You can then employ a mallet or hammer to separate the stiles from the rails and inspect them for damage or for any repairs that must be made.

After inspecting the rails and stiles of the sash, put some dust sheets on the floor and start working. Begin by taking the wood pegs out of the mortise and tenon joints with a pin punch and a hammer or screwdriver. Once the pegs are gone you can begin disassembling the sash by removing the sash stop moldings, pulling off any sash cord knots still attached and, finally, taking the sash off itself.

Next you will want to weigh the sash and determine the amount of weight is needed to ensure its proper functioning. You can find vintage replacement sashweights on the internet or in some home improvement stores. Make sure you get the correct size to avoid over or under-weighting the sash.

Sash Cords

Often sash window problems stem from broken or worn sash cords. The weights exert constant pressure on the sash cords and this can cause them break over time. The sashes will not open or close as easily when the cords break. The issue could be caused by a number of things like excessive force, aging, the lack of maintenance and moisture buildup. It is essential to replace the old cords in window sash repair with new ones made of materials that are robust and resistant to moisture.

Begin by removing the internal stops, the thin pieces of wood that keep the sashes in place, using a knife or a the chisel. Take care to remove the stops of the sashes, keeping an eye on any that are cracked or broken. After removing the stops, you can access the weights on the sash by opening the jamb or removing the weight pocket.

It requires a bit of work to reach the sash cords but with the right tools and a little bit of patience, it's not difficult. First, you must remove the old cords by cutting them close to their knots and then pulling them out. Remove the sash and set it aside. Pull down the staff bead, the nail that holds the sash in position. Insert the nail about a foot length into the hole. This will keep the sash in place as you finish stringing counterweights.

After installing the upper sash then reattach the sash cords and make sure the sashes are properly balanced and move smoothly. Reinstall the lower sash and repeat the procedure. Make sure that the sashes have been properly set and are moving in a smooth manner.

Once you've completed installing counterweights, connect the sash cords by placing a sash cord through the pulleys and threading the other end of the cord through a knot hole inside the sash to secure it into the correct position. Repeat this procedure on both sides of the sash to ensure that the sashes work as intended again.

Air leaks and drafts

Over time, the components that seal sash windows to your frame begin to degrade, resulting in drafts and energy loss. A thorough inspection can identify problems and help you choose your window sash repair options. Your personal preferences for comfort and your ability level determine whether you are able to manage window repairs to your sash or require professional input. The scope of work required is also affected by the historical property status and structural strength.

When cold air sneaks in through a drafty window, your furnace must work overtime to keep your house warm. This inefficiency increases your heating bills, and can affect the efficiency of your HVAC system. In addition, drafts affect your indoor comfort and can degrade indoor air quality by forcing the infiltration of outdoor pollutant, allergens, and humidity.

A common sign of a drafty window is the feeling of cold air circulating through your home despite all doors and windows being closed. Other tell-tale signs include a fluctuation in the temperature of your home near the window and condensation on the frame or sill.

It is good to know that fixing drafty windows is a relatively simple job that can lower your energy bills and improve the indoor comfort. First, look at the outside of the window. Check for wood that isn't bare and areas where the old caulking is cracked, opening the gaps to cold air.

Examine the sash's interface to the frame including the parting bead and staff bead. Examine the condition of the weather stripping (felt strips or foam tape) at these locations to determine if it's intact and functional. If not, it's time to be replaced.

Then, think about the condition of glazing putty, which is a tough putty that holds panes glass in place. Check for cracks and crumbling that can expose the sash's surface to moisture. This could lead to mold issues and damage to the glass.

Apply a new layer of glazing putty on the outside of the window to correct the issue. Utilizing a flat-blade screwdriver push the glazing points into position to fix them. Wrap a piece or fabric and then foam around each point. This acts as an insulation against cold air.

Remove these with the blade of a small pry bar or a putty blade - they are normally nailed in place and stuck by paint, so you need be cautious not to damage them or the sash.

After removing the parting beads you'll have to remove the pockets. These are tiny pieces of wood that are screwed to the frame at the bottom. They permit access to the sashweights. Once they are removed, the sash can be moved between the two sides to ensure that it moves smoothly.
