Window Sash Repairs
The majority of homeowners don't think too much about window sashes -- so long as they are able to are closed, open, and keep the outside air out and the air inside in. As time passes windows sashes become worn out and lead to drafts, air leaks or even sashes that are stuck.

Sash Weights
If your windows are not closing and opening smoothly or are sluggish the way they should, a defective counterbalancing system could be at fault. This could be due to a missing or damaged chain/sash cord or an unattached or misaligned sash weight, or a broken pulley.
The sash weights are tiny boxes, typically made of cast iron, that help support the sash and also support the counter-weight system in the window. They are situated in the bottom rails of every window frame, covered by an access panel of wood that can be cut open to reveal their whereabouts. The panels can be removed to gain access to the sash weight pockets to clean, repair or replacement.
If you've had sash windows for some time, you may have a problem with the sash weights, which cause them to sag or catch. This can be due to the weights being too heavy (they are supposed to be a bit heavier than the top sash) or because they were installed in a way that isn't correct (some people disabled their weight systems by cutting them off and taking the weights out to save money or turning them in for scrap metal).
To fix this problem, first pull off the stops (the trim along the inside edges of the window where it joins the frame and holds it in place) and set them aside. It is important to do this with care so as to not damage the shape of the two rails. Then you can employ a mallet or hammer to break the rail and stiles and examine the rails for damage or any repairs that require to be made.
Once you've inspected the rails and stiles, lay down dust sheets and begin working on the sash itself. Start by removing wood pegs using a pin-punch and a hammer or screwdriver from the mortise-and tenon joints. Once the pegs are gone then you can begin disassembling the sash by taking out the sash stop moldings and removing any sash cord knots still in place, and finally, taking the sash off itself.
Next you will want to weigh the sash and determine the amount of weight is needed for the proper functioning. You can find vintage weights for sash replacement online or at some home improvement stores, but be sure to purchase the correct size so as not to under or over weigh the sash.
Sash Cords
Sash cords that are worn out or damaged can cause problems with the sash window. Sash cords are under constant pressure from the weights which can cause them to break over time, especially when they're not maintained properly. The sashes won't open or close as easily if the cords break. The issue could be caused by excessive force, ageing or lack of maintenance or the buildup of moisture. During window sash repairs it is crucial to replace the old cords with new ones made from a material that will last and resist moisture.
Begin by removing the inner stop strips, the thin wood strips that hold the sashes in place Utilizing a utility blade and a chisel. Take care to remove the stops of the sashes, while keeping an eye out for cracks or broken. Once the stops are removed, you will be able to access the sash's weights by using an access panel cut into frame's bottom, or by opening the jamb and removing the cover for the weight pocket.
It requires a bit of work to reach the sash cords but with the proper tools and a bit of patience, it's not difficult. Remove the old cords first by cutting them in their knots, then pulling them out. Then, take the sash from the frame and put it aside. When the sash is removed, pull down on the staff bead (the nail that stops the sash from falling) and insert the nail, which is about 1 foot into the hole for the staff bead. This will temporarily stop the sash from slipping away while you string the counterweights.
Reattach the sash string after installing the upper sash. Verify that the sashes are moving smoothly and are balanced. Reinstall the lower sash and repeat the process. Verify that the sashes have been properly placed and are moving in a smooth manner.
Reattach the sash cables after you have installed the counterweights. Thread the cord through the pulleys and then through the knot hole in the sash. Repeat the process for each side of the sash until all cords are replaced and the sashes function normal.
Drafts and Air Leaks

Examine the sash's interface with the frame. This includes the parting beads, and the staff bead. Check the condition of weather stripping in these areas (felt strips or tape) to determine if they're intact and working. If not, it's time to be replaced.
Consider the condition of glazing putty. It's a hard putty used to hold panes of tempered glass in place. Examine for cracks or crumbling that exposes the sash to moisture, which could cause mold issues and damage to the windows' glass.
Apply a fresh layer glazing putty on the inside of the window to correct the issue. To secure the glazing points make use of a flat-bladed screwdriver push them into position. Wrap a fabric or piece and foam around each point. This will act as insulation against cold air.

The first step is to lower the upper sash down to the bottom. This is generally easy and will give you a clear view of the "parting beads" (these are the grooved bits in the meeting rail on either side that keep the two sliding sashes separate). Take them off using the blade of a small pry bar or a putty blade - they are usually nailed into place and stuck with paint so you need be careful not to damage them or the sash.
After you have removed the parting beads, you'll need to take off the covers for your pockets. These are bits of wood inside the frame, low down, that allow access to sash weights. They are usually fixed with nails - they can also be stuck with paint, so you have be cautious. After the nails have been removed then you can move the sash up and down in order to make sure it moves in a smooth manner.
