Sash Weights
If windows aren't opening and closing with ease or are sagging due to a problem with the counter-balancing system, it's possible that a may be to blame. This can occur because of a broken or damaged sash chain or cord as well as a misaligned or unattached sash weight, or a broken pulley.
The sash weights are tiny boxes constructed of cast iron that help support the sash and also help balance the counter-weight system of the window. They are situated in the bottom rails of every window frame, covered by a wooden access panel which can be opened to reveal their whereabouts. 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 likely have an issue with the sash weights, which cause them to lean or catch. The weights may be too heavy (they should be a little heavier than the top sash) or installed incorrectly.
To fix this problem take out the stops (the trim that runs along the inside of the window at the point that it joins with the frame to keep it in position). Set them aside. This will require you to be gentle in order to not scratch the appearance of your overlapping rails. You can then use a hammer or mallet to separate the stiles and rails and check them for damage or any repairs that must be made.
Once you've inspected the stiles and rails, lay down dust sheets and begin working on the sash itself. Start by taking the wood pegs out of the mortise and the tenon joints using pin punches and a screwdriver or hammer. After you have removed the pegs you can begin disassembling the sash. Remove the sash stop moldings and any sash cords still in place.
The next step is to weigh the sash in order to determine the amount of weight is needed to ensure its proper operation. You can find old replacement sash weights online or at a few home improvement stores, but ensure that you purchase the right size so as not to over or under weight the sash.
Sash Cords
Sash cords that are worn out or broken can lead to sash window issues. The weights put pressure on the sash cords, and this can cause them break over time. If cords break, sashes won't be able to open and close easily. The issue could be caused due to excessive force, aging, lack of maintenance, or the buildup of moisture. In the case of window sash repairs it is crucial to replace the old cords with new ones that are made from an material that lasts and resist moisture.
Begin by removing the internal stops and the thin strips of wood that keep the sashes in place using a knife or a Chisel. Pry the stops from the sashes with care and keep an eye out for cracked or broken ones. Once the stops are removed, you can access the sash weights through an access panel cut into the bottom of the frame or by opening the jamb and taking off the cover that covers the weight pocket.
It may take a bit more effort to reach the sash cords, but with the right tools and a bit of patience, it's not difficult. First, take off the old cords by cutting them near their knots and pulling them free. Then, take the sash from the frame and set it aside. Take off the staff bead, the nail that keeps the sash in its place. Put a nail of about a foot into the hole. This will hold the sash on its place while you string counterweights.
After installing the upper sash, reattach the sash cords and make sure the sashes are properly balanced and move smoothly. Then, install the lower sash and repeat the process, checking that the sashes are properly sitting and moving smoothly.
After you've finished installing the counterweights, reconnect the sash cords, by inserting an sash cord into the pulleys and threading the cord's other end through a knot hole in the sash to secure it into the correct position. Repeat click through the following website on each side of the sash, making sure that the sashes work as intended 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 loss of energy. A thorough inspection can identify the trouble spots and help you decide on the options for fixing your window sash. Your personal preferences for comfort and your ability level determine whether you are able to manage window repair or require expert input. The scope of work is also influenced by history of the property's condition and the structural strength.
If cold air is getting in through a drafty door or window, your furnace will be forced to work harder to warm your home. This can result in higher heating costs and could affect the efficiency of your 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 can be identified by the sensation of cold air coming into a room, even when all windows and doors are shut. Other tell-tale signs include an increase in the temperature of your home close to the window and condensation around the frame or sill.
It is good to know that fixing drafty windows is a relatively simple job that can lower your energy costs and enhance the indoor comfort. The first step is to examine the window's exterior. Examine for bare wood and areas where the old caulking is cracked, opening the gaps to cold air.
Examine the interface of the sash with the frame. This includes the parting beads, and the staff bead. Examine the condition of the weather stripping on these points (felt strips or tape) to determine if they're in good condition and functional. If not, this needs to be replaced.
Examine the condition of glazing putty. This is a hard putty used to hold panes of glass tempered in place. Look 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 to the inside 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 will act as insulation against cold air.

First, lower the upper sash to the bottom. This is generally simple and will allow you to observe the "parting beads" which are the grooved bits on the rails at the junction which keep the two sliding sashes apart. They can be removed by a blade from the small pry-bar or putty-knife. They are usually nailed into place and painted, so you need to be careful not to damage them or the sliding sash.
After removing the parting beads you'll have to remove the pocket covers. These are pieces of wood inside the frame, low down, that allow access to sash weights and are normally fixed with nails - they may also be snagged with paint so you need to be careful. Once they've been removed, the sash will be moved up and down to ensure that it is moving smoothly.
