Window Sash Repairs

The majority of homeowners don't pay attention to window sashes, as long as they are capable of being opened and closed and keep the air inside and the air outside out. Over time, window sashes can become worn out and lead to drafts, air leaks or even sashes that are stuck.

Sash Weights

If your windows aren't opening and closing smoothly, or are stuck in a stuck position, a malfunctioning counterbalancing system could be the reason. It could be caused by a damaged or missing sash chain or a sashweight that is not aligned properly or not attached to a weight, or a damaged or damaged pulley.

The sash weights are small boxes, usually made of cast iron that serve to support the sash as well as help balance the counter-weight system of the window. They are found in the bottom rails of each window frame and are covered with a wooden access panel which can be opened to reveal their whereabouts. These panels can be removed for access to the pockets of sash weights to clean, repair or replacement.

If you've been using sash windows for a long time, you may have a problem with weights on the sash that cause them to sag or catch. This can be caused by the weights being too heavy (they are supposed to be a bit heavier than the top sash) or due to them being installed in a way that isn't correct (some people disabled their weight systems by cutting them and removing the weights to save money, or turning them in for scrap metal).

To resolve this issue take out the stops (the trim that runs along the inside edge of the window where it joins with the frame to hold it in place). Set them aside. This requires you to be gentle in order to not scratch the shape of your meeting rails. You can then use a hammer for separating the stiles and rails and then inspect them for damage.

Once you've inspected the rails and stiles, lay down dust sheets and begin working on the sash itself. Begin by removing the wood pegs using a pin-punch and a screwdriver or hammer from the mortise-and-tenon joints. After the pegs have been removed then you can begin to disassemble the sash by removing the sash stop moldings, pulling off any sash cord knots still connected, and then taking the sash off itself.

The next step is to weigh the sash and determine the amount of weight is required for the proper functioning. You can find old weights for replacement on the internet or at a few home improvement stores, but be sure to buy the right size so as not to over or under weight the sash.

Sash Cords

Most sash window issues stem from damaged or worn sash cords. The weights exert constant pressure on the sash cords, which can cause them to break over time. If the cords break, the sashes will no longer open and close easily. The issue could be caused by a number of reasons, including excessive force, aging, a lack of maintenance and moisture buildup. During window sash repairs it is essential to replace the old cords with new ones that are constructed from an material that lasts and resist moisture.

Begin by removing the inner stops which are the thin strips of wood that keep the sashes together using a utility knife and a the chisel. Pry the stops off the sashes carefully, and be on the lookout for any broken or cracked ones. Once the stops are removed, you will be able to access the sash weights via an access panel cut into frame's bottom, or by opening the jamb, and then removing the weight pocket cover.

Accessing the sash cords takes some extra effort however it's not too difficult with the right tools and patience. Take the old cords out first by cutting them at their knots, then pulling them out. Take the sash off and set it aside. Once the sash is off then pull it back down on the staff bead (the nail that stops the sash from falling) and insert the nail, which is about one foot long into the hole for the staff bead. This will hold the sash in place while you string counterweights.

Reattach the sash strings after reinstalling upper sash. Verify that the sashes are moving smoothly and are balanced. Then, install the lower sash and repeat the process, ensuring that the sashes are properly in place and are moving smoothly.

After you've installed counterweights, connect the sash cords, by inserting an sash cord into the pulleys and then threading the other end of the cord through a knot hole inside the sash to secure it in place. Repeat this process for the opposite side of the sash to ensure that the sashes function normally again.

Air and drafts Leaks

As time passes, the materials that connect sash windows to the frame begin to degrade which can cause drafts and energy loss. A thorough inspection will reveal the trouble spots and help you determine the best options for repairs to your window sash. Your comfort preferences and skill level influence whether you can self-manage window repairs to your sash or require professional assistance. The historical status of your property and structural integrity issues also affect the scope of work required.

If cold air is coming in through a drafty door or window, the furnace will have to work overtime to warm your home. This inefficiency can eat into your heating bills and compromises the efficiency of your HVAC system. Additionally, drafts can disrupt your indoor comfort and can degrade the quality of your indoor air by bringing the infiltration of outdoor pollutants, allergens and humidity.

A drafty window can be identified by the sensation of cold air rushing into an area, even though all windows and doors are closed. Other indicators to look out for are changes in temperature near the window, and condensation around the sill or frame.

Repairing drafty windows is a an easy task that will lower your energy bills and increase comfort inside. Start by inspecting the outside of the window. Look for bare wood and areas where the caulking has cracked, exposing the gap to cold air.

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

Finally, consider the state of glazing putty, a hard putty that holds panes glass in place. Look for cracks or crumbling that exposes the sash to moisture which can cause mold issues and damage to the glass of windows.

To resolve the problem, apply a layer of fresh glazing putty on the inside of your window. To fix the glazing points, use a flat-bladed screwdriver to push them into the right position. Wrap a piece or fabric and then foam around each point. This will act as insulation against cold air.

Aesthetics

The cost of a sash repair is usually less than the cost to replace the whole window, and it can help save you money on energy bills as well.

The first step is to lower the upper sash down to the bottom. This is generally easy and will help you get an unobstructed view of the "parting beads" (these are grooved bits in the rail that connects either side that keep the 2 sliding sashes apart). Remove these with the blade of a small bar or a putty knife - they are typically nailed in place and stuck by paint, so you need to be careful not to scratch them or the sash.


After removing the beads that separate, you'll need to take off the covers for your pockets. These are tiny pieces of wood which are fixed to the frame at the bottom. They permit access to the sashweights. Once the nails are removed you can move the sash upwards and downwards in order to make sure it moves smoothly.

If it's not, there might be an issue with the counterweights or the sash cords. After you've inspected them all, you can fix them if necessary.
