Window Sash Repairs

The majority of homeowners don't think too much about window sashes insofar as they open, close, and keep outside air out and the air inside in. But with time, they can begin to wear out, causing drafts, air leaks, or even sticking sashes.

The artist uses the sash which is placed on an easel for working glazing points into the gap. He also scrapes paint off and then applies a wood preservative to the frame.

If your windows are not closing and opening smoothly or are sluggish, a faulty counterbalancing system could be the cause. This can occur due to a damaged or damaged sash chain or cord, an unattached or misaligned sash weight, or a broken pulley.

The sashweights are tiny boxes made of cast-iron, which balance the counter-weight system as well as support the sash. The sash weights are located on the bottom rails of every window frame. They are covered with an unfinished wooden panel that can be removed to reveal their position. The panels can be removed for access to the sash-weight pockets to clean, 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 sag or catch. The weights can be too heavy (they should be a little heavier than the top sash), or installed incorrectly.

To fix this issue, first pry off the stops (the trim along the inside edges of the window where it joins the frame and keeps it in place) and then set them aside. This requires you to be gentle so as to not harm the appearance of your overlapping rails. Then, you can use a hammer or mallet to break up the stiles and rails and check them for damage or any repairs that require to be made.

After inspecting the rails and stiles of the sash dust sheets on the floor and begin working. Start by removing the wood pegs from the mortise and tenon joints with pins and a screwdriver or hammer. Once the pegs are removed, you can begin to disassemble the sash by removing the sash stop moldings and removing any box sash window cord knots in place, and finally, taking the sash off itself.

Next, you will need to weigh the sash to determine how much weight it will require for functioning. You can find vintage weights for replacement on the internet or in some home improvement stores, but you should be sure to purchase the correct size so as not to overload or underweight the sash.

Sash Cords

The majority of sash window problems result from broken or worn double glazed sash window cords. The weights put pressure on the sash's cords which can cause them to break over time. The sashes won't be able to open or close as easily if the cords break. The issue could be caused due to excessive force, aging, lack of maintenance, or moisture buildup. It is essential to replace the old cords in window sash repairs with new ones made of a material that is strong and resistant to moisture.

Begin by removing the inner stop strips, thin wood strips that hold the sashes into their place with a utility knife and a the chisel. Remove the stops out of the sashes with care and be on the lookout for cracked or broken ones. After the stops have been removed, you will be able to access the sash's weights by using an access panel cut into the frame's bottom, or by opening the jamb, and then removing the cover for the weight pocket.

It takes a little extra work to reach the sash cords, but with the proper tools and a bit of patience it is not difficult. First, take off the old cords by cutting them close to their knots and pulling them free. Then, you can remove the sash from the frame and set it aside. After the sash has been removed, pull down on the staff bead (the nail that stops the sash from falling) and insert the nail, which is about a foot long into the staff bead hole. This will hold the sash on its place while you finish stringing counterweights.

After installing the upper sash again, reattach the sash cords and ensure that the sashes are properly balanced and move smoothly. Then, reinstall the lower sash and repeat the process, checking that the sashes are properly in place and are moving smoothly.

Once you've completed installing the counterweights, reattach the sash cords by putting the sash cord through the pulleys and threading the other end of the cord through a knot hole in the sash to secure it into the correct position. Repeat this procedure for each side of the sash until cords have been replaced and the sashes are operating normally.

Drafts and Air Leaks

Over time, the materials that connect sash windows to the frame begin to degrade creating drafts and energy loss. A thorough inspection can reveal problems and help you choose your window sash repair options. Your comfort preferences and skill level influence whether you are able to handle window sash repairs or require professional input. The scope of work required is also affected by the historical property status and the structural integrity.

If cold air is getting through a drafty or drafty door or window, the furnace will need to work harder to warm your home. This inefficiency is a drain on your heating bills and compromises the efficiency of your home's HVAC system. Drafts can also impact the quality of indoor air and cause discomfort in the home by adding allergens, pollutant, and humidity from the outside.

A drafty window is evident by the sensation of cold air coming into a room, even when all doors and windows are closed. Other signs to be aware of are changes in temperature near the Casement Window Sash, and condensation around the frame or sill.

It is good to know that fixing drafty windows is a simple job that can lower your energy bills and improve the comfort of your home. The first step is to examine the exterior of the window. Look for bare wood and areas where the caulking has cracked, opening the air gap.

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

Take a look at the condition of the glazing putty. It's a hard putty used to hold panes of glass that has been tempered in place. Check for cracks and a crumbling surface that could expose the sash's exterior to moisture. This can cause mold issues and damage to the glass.

Apply a fresh layer of glazing putty on the outside of the window to fix the problem. Utilizing a flat-blade screwdriver push the glazing points in place to hold them. Wrap a piece of fabric and foam around each point. This will act as insulation against cold air.

Aesthetics

Window repair can give old windows a fresh new look for less money than an entire window replacement. A complete window replacement can be an expensive and time-consuming project, especially for older homes. Repairing window sashes can be a great way to restore the beauty of your home and value.

Be vigilant about the condition of windows sashes is essential to avoid major problems. If you're not sure if your windows are in need of repair, it's recommended to have them assessed by an expert. A sash repair could be much cheaper than replacing the entire window and can also help you save money on energy bills.

First, lower the upper sash to the bottom. This is usually easy and allows you to see the "parting beads" that are grooved bits on the meeting rails which keep the two sliding sashes separate. They can be removed using a blade that is attached to a small pry-bar or a putty knife. They are typically put in place with nails and then painted, so be careful not damage them or the sliding sash.

Once you've removed the parting beads, the next job is to remove the pockets. These are bits of wood within the frame, low down, which allow access to the sash weights and are normally fixed with nails - they could also be glued with paint so you need be extra cautious. Once the nails are removed, you can move the sash up and down to ensure it moves smoothly.

If it doesn't, it might be an issue with the counterweights, or the sash cords. Once you've checked all of these, you can fix them as required.
