Window Sash Repairs
Most homeowners don't think how much do wooden sash windows cost about window sashes insofar as they are closed, open, and keep the outside air out and the inside air in. 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 closing and opening smoothly or are sluggish, a faulty counterbalancing system could be the cause. This could be due to a missing or damaged chain/sash cord or an unattached or misaligned sash weight, or a damaged pulley.
The sash weights are tiny 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 situated in the bottom rails of each window frame, and are covered by an access panel of wood which can be opened to reveal their location. The panels can be removed for access to the sash weight pockets for cleaning, repairs or replacement.
If you've had sash windows for some time, you may have a problem with weights on the sash that cause them to sag or catch. The weights can be too heavy (they should be a bit heavier than the top sash) or they've been installed incorrectly.
To correct this problem, first pull 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 will require you to be careful so as to not scratch the appearance of your overlapping rails. Then, you can employ a mallet or hammer to break the rail and stiles and check them for damage or for any repairs that must be made.
After you've examined the stiles and rails, lay down dust sheets and then begin working on the sash itself. Begin by taking the wood pegs out of the mortise and the tenon joints using pin punches and a hammer or screwdriver. Once the pegs are removed, you can begin disassembling the sash by taking out the sash stop moldings and removing the sash cord knots that are 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 to ensure its proper functioning. You can find vintage replacement sash weights online or at a few home improvement stores, but be sure to purchase the right size to ensure not to under or over weigh the double glazed sash window.
Sash Cords
Sash cords that are worn out or broken can lead to problems with sash windows. Sash cords are under constant pressure from the weights, which could cause them to break over time, especially when they're not maintained correctly. If the cords break, sashes won't be able to open and close easily. The issue could be caused by a number of reasons like excessive force, aging, lack of maintenance, and the accumulation of moisture. In the case of window sash repairs, it's important to replace the old cords with new ones that are made of a material that will last and resist moisture.
Begin by removing the inner stop strips, thin wood strips that hold the sashes in the frame, using a utility blade and a the chisel. Pry the stops out of the sashes with care and keep an eye out for cracked or broken ones. After the stops have been removed, you can access the sash weights via an access panel cut into the bottom of the frame or by opening the jamb and removing the cover for the weight pocket.
It may take a bit more effort to reach the sash cords but with the proper tools and a bit of patience it is not difficult. Get rid of the old cords first by cutting them at their knots and then pulling them out. Then, you can remove the sash from the frame and put it aside. When the sash is removed and you have pulled it down, grab the staff bead (the nail that prevents the sash from falling) and then insert one nail that is about one foot long into the staff bead hole. This will temporarily keep the sash from falling as you string the counterweights.
After reinstalling the upper sash then reattach the sash cords and make sure the sashes are balanced and move smoothly. Install the lower sash and repeat the procedure. Make sure that the sashes have been properly seated and are moving in a smooth manner.
After you've finished installing the counterweights, reattach 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 the correct position. Repeat the process for each side of the sash until all cords are replaced and the sashes are operating normally again.
Air leaks and drafts
As time passes, the materials that seal sash windows to your frame begin to degrade creating drafts and energy loss. A thorough inspection can identify the areas of concern and assist you in determining your window sash repairs options. Your personal preferences for comfort and your skill level influence whether you are able to handle window repair or require expert assistance. The scope of work is also influenced by the history of the property's condition and structural strength.
If cold air is coming in through a drafty door or window, the furnace will need to work harder to warm your home. This inefficiency can eat into your heating bills and compromises the efficiency of your home's HVAC system. Drafts can also affect indoor air quality and affect indoor comfort by the infiltration of allergens, pollutants and humidity from the outside.
A drafty window is evident by the feeling of cold air entering an area, even though all doors and windows are shut. Other indicators to look out for include a fluctuation in the temperature of your room close to the window and condensation around the frame or sill.
Fortunately, fixing drafty windows is a easy task that can cut your energy bills and improve indoor comfort. Start by inspecting the outside of the window. Look for areas of bare caulking that is cracked or wood that exposes the window to cold air.
Examine the interface of the sash 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 points to determine if they are intact and working. If not, it's time to be replaced.
Take a look at the condition of the glazing putty. It is a tough putty used to hold panes of tempered glass in place. Check for cracks and crumbling that can expose the sash's exterior to moisture. This can cause problems with mold and damage to the glass.
Apply a fresh layer glazing putty on the outside of the window to fix the problem. Utilizing a flat-blade screwdriver push the glazing points into position to fix them. Then wrap a piece foam and fabric around each point to create an insulation lawyer against cold air.
Aesthetics
Window repair for sash windows can give older windows a new look at a lower cost than a complete replacement. A complete window replacement could be costly and time-consuming undertaking, particularly for older homes. Repairing window sashes can be a great way to restore a home's original beauty and value.

The cost of a sash repair is usually less than the cost to replace the whole window, and it can help reduce your energy bills in the process.
The first step is to lower the upper sash to the bottom. This is usually easy and will help you get an excellent view of the "parting beads" (these are grooved pieces in the rail that connects either side that keep the two sliding sash windows sashes apart). Remove these with the blade of a small pry bar or a putty knife they are usually nailed into place and stuck by paint, so you need to be careful not to damage them or the sash.
After you've removed the parting beads, the next step is to take off the pocket covers. These are tiny pieces of wood which are fixed into the frame at the bottom. They provide access to the sashweights. After they have been removed, the sash can be moved up and down to check that it moves smoothly.
If it doesn't, it may be a problem with the counterweights or sash cords. After you've checked them all you can fix them if you need to.
