Window Sash Repairs

The majority of homeowners don't give much thought to window sashes, so long as they're capable of opening and closing and keep the air inside and the outside air out. However, over time, they can get worn out, leading to air leaks, drafts, or even sticking sashes.

The author makes use of the sash which is propped up on an easel to work the glazing points into the gap. He also scrapes paint off and applies an oil-based preservative to the frame.

Sash Weights

If windows aren't opening and closing smoothly or are sticking due to a problem with the counter-balancing system, it's possible that a could be the cause. This could be due to a damaged or missing sash chain, a misaligned or unattached the sashweight, or even a broken or damaged pulley.

The sash weights are small boxes, usually constructed of cast iron that help support the sash and also support the counter-weight system in the window. They are found in the bottom rails of every 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 weight pockets in the upvc sash windows to clean, repair or replacement.

You may have a problem with the sashweights if been using your sash windows for over a period of time. They may lean or catch. The weights may be too heavy (they should be a bit heavier than the top sash), or installed in a way that isn't correct.

To correct this issue, first take off the stops (the trim along the inside edges of the window where it joins the frame and holds it in the frame) and set them aside. This will require you to be gentle so as to not damage the shape of your meeting rails. You can then use a hammer or mallet to break up the rail and stiles and inspect them for damage or any repairs that must be made.

After you've checked the stiles and rails, lay down a few dust sheets and start working on the sash itself. Begin by removing the wood pegs from the mortise and tenon joints using a pin punch and a hammer or screwdriver. After removing the pegs, you can begin disassembling the sash. Take off the sash stop moldings as well as any sash cords still in place.

The next step is to weigh the sash and figure out how much weight is required for its proper functioning. You can find old weights for replacement on the internet or in some home improvement stores, but you should ensure that you purchase the correct size so as not to overload or underweight the sash secondary glazing.

Sash Cords

Often sash window problems stem from broken or worn sash cords. The weights exert constant pressure on the sash cords and this could cause them to break over time. If cords break, sashes will not be able to open and close easily. The problem could be caused by a number of reasons that can cause it, such as excessive force, aging, a lack of maintenance or accumulation of moisture. During window sash repairs it is essential to replace the old cords with new ones constructed from a material that will last and resist moisture.

Begin by removing the internal stops which are the thin pieces of wood that keep the sashes in place, using a knife or a Chisel. Pry the stops off the sashes with care, and keep an eye out for any broken or cracked ones. After removing the stops, you can get access to the sashweights by opening up the jamb or removing the weight pocket.

It requires a bit of effort to reach the sash cords, but with the right tools and a bit of patience it is not difficult. First, take off the old cords by cutting them close to their knots, and then pulling them away. Take the sash off and set it aside. When the sash is removed and you have pulled it down, grab the staff bead (the nail that stops the sash from falling) and then insert the nail, which is about 1 foot into the hole in the staff bead. This will keep the sash in place while you finish stringing counterweights.

After reinstalling the upper sash, reattach the sash cords and make sure the sashes are balanced and move smoothly. Then, reinstall the lower sash, and repeat the process, making sure that the sashes are seated and moving smoothly.

After you've finished installing counterweights, connect the sash cords, by inserting the sash cord through the pulleys and then threading the other end of the cord through a knot hole in the sash to secure it in the correct position. Repeat this process on both sides of the sash to ensure that the sashes work as intended again.

Air and drafts Leaks

Over time, the materials that seal your sash window to the frame of your home deteriorate. This causes drafts and energy loss. A thorough inspection can identify the problem areas and help you determine your window sash repairs options. Your comfort level and level will determine whether you are able to manage your own repairs or require professional assistance with window sash repair. The scope of work is also influenced by historic status of the property and its the structural integrity.

If cold air is coming in through a drafty door or window, your furnace will have to work harder to warm your home. This inefficiency is a drain on your heating bills and compromises the efficiency of your HVAC system. Drafts can also reduce the quality of air inside and affect indoor comfort by the infiltration of allergens, pollutants and humidity from outside.

A drafty window is evident by the feeling of cold air entering a room, even when all windows and doors are shut. Other tell-tale signs include an increase in the temperature of your room close to the window and condensation on the frame or sill.

Fortunately, repairing drafty windows is a simple task that can reduce your energy bills and improve the comfort of your home. First, look at the exterior of the window. Look for bare wood and areas where the old caulking has cracked, opening the gaps to cold air.

Examine the sash's connection to the frame, including the parting bead and staff bead. Examine the condition of weather stripping at these points (felt strips or tape) to determine if they are intact and effective. If not, this needs to be replaced.

Then, think about the condition of glazing putty. It is a hard putty that keeps panes of glass in place. Check for cracks and crumbling that can expose the sash's surface moisture. This can lead to problems with mold and damage to the glass.

Apply a new layer of glazing putty to the inside of the window to fix the issue. To fix the glazing points, employ a screwdriver with a flat blade to push them into position. Then, wrap a piece of foam and fabric around each point to form an insulation layer against cold air.

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

The first step is to lower the upper sash down to the bottom. This is generally simple and will allow you to observe the "parting beads", which are grooved bits on the rails that keep the two sliding sashes separated. You can remove them using the blade of a small pry bar or a putty blade - they are usually nailed into place and stuck with paint, so you have to be careful not to harm them or the sash.

After you've removed the parting beads, the next step is to remove the pocket covers. They are tiny pieces of wood that are screwed to the frame at the bottom. They permit access to the sashweights. After the nails have been removed then you can move the bespoke sash windows up and down to ensure it moves easily.

If it's not, there may be problems with the counterweights or sash cords. After you've checked them all, you can fix them if necessary.
