Weather Stripping
Weather stripping is a thin flexible strip of material used to protect the edges of windows and doors when they are closed. It blocks out outside air and the harmful substances it holds. It prevents drafts from entering the gaps and making your home too cold or letting outside noises through. You can buy ready-to-use weather stripping in rolls with different dimensions, or you can cut the material to size to fit the window sashes.
Install the strip between the meeting bar and sash for windows with a single hung. The same procedure is applied to the lower and upper sashes. Apply the same strips on the frame side to stop rattle.
Weather strips are required on both sides of double-hung windows. You may also have to put strips on the inside of the frame near the bottom. The strips stop the window from closing and also prevent dust and insects from blowing through the gap between the sash and jamb.
Before installing the weatherstripping clean the sash frame with mild soap and warm water. Dry it with a soft cloth. The utility knife is used to remove any caulk and paint from the interior stops. Make sure to remove the stops carefully with a putty knife to protect the frame. Replace the weather stripping.
The new weather stripping must be flexible enough to allow for the sash's movement, but firm enough to hold in place when closed. Adhesive-backed foam tape is a popular option. It's easy to use, and it is available in various sizes to meet the needs of different people. Door sweeps are available in many sizes and types, and can be used on all kinds of windows and doors.
Compare the metal tabs of the new sash with those on the old sash prior to you install it. If the tabs are of a different shape they won't fit in the slot on the window frame correctly, and you'll have to take the sash off and start from scratch. Individual replacements for sash don't cost a lot and a complete window replacement isn't going to be a huge expense.
Start by removing the outer separation bead - the thin strips of wood that make up the inner and outer frame. It is possible that they are fixed in place however a hammer and nail set will be enough to accomplish the task. Be sure to lay down a tarp since sash windows can be messy and can cause damage to paint and possibly rotting wood especially in older homes. Wear a mask since dust can contain lead.
Then, take out the upper sash and its cords. If you're not planning to put new cords in, simply cut the old ones and tie them so they can't pass through the holes in the sash. If you're putting in new cords, first take out the nail that binds each one to the sash and pull out the nails that hold each of the cords to the sash (the nails are known as glazier's points). Then, if the pockets on either side of the frame are in place, take them open using the hammer and nail set or the help of a crowbar. It is likely that you will need to remove some of the old sash material.
When the pockets are empty then you can take off the sash that covers the frame and you'll be able to see the channels on either side of the frame where the cords for the sash go through. If you're putting in new sash cords, opt for cotton ones. They will last longer than synthetic cords, which stretch and slide. You'll also need to ensure that you have the correct amount of weight for each sash. You can weigh them using a kitchen scale to make sure, but the weights should be approximately half the size of the sash.
If the tilt pin at the bottom of the lower sash is still in place, reset it. To accomplish this, you'll need to raise the lower sash just a bit. Be cautious not to let it fall. Then, lock the pin. Then, put in an additional sash weight (the tube that holds the weights) and you're done! (Don't forget to verify and lock the tilt pin that is on the upper sash.)
Parting Beads
Parting beads (vertical wood strips holding the lower sash in place) and staff beads are essential components of a Sash. They help to retain the weights of sash windows, stop water ingress and create a seal between the inner and outer boxes. These could cause excessive draughts or rattle if they are damaged or in a poor condition.
Use a sharp knife and slice along the paint joint between the parting beads as well as the box window frames. Examine for nails or screws before gently removing the parting beads out of their narrow grooves. They are designed to fit snugly, but they may have been secured with nails. Remove any sash cords that are nailed.
After the parting bead has been removed, it is possible to take the lower sash out and then remove the meeting rail (which is affixed to the bottom sash on a double hung sash) from both sides. The meeting rail can be lifted out of the frame, allowing you to view the windows.
You can clean the sash windows and re-attach any sash furniture/ironmongery, lubricate the pulley axles & test the operation of the window. If you have difficulty lifting or closing the window, it could be worthwhile to consider other sash balance systems. They are discussed in a different article.
To make the sash windows weatherproof again apply draught strip and paint (with a good quality oil-based primer). Alternatively sand down to smooth and then apply multi-purpose putty. Apply a small amount of "fronting putty' to the area where the glazing rebates meet with the internal sash sash upstand. Then, you can front it into the putty with a fillet to create a smooth edge. Finish a few millimeters below the sightline. Replace the sash cords, re-tie knots if needed, and re-hang the window. Consider using white 6mm braided marine rope or cord as this will last much longer than the cheap cords that stretch over time. It will also help you close the sash windows by decreasing the distance between the frame and the window.
Glass
Most homeowners don't take the time to spend much time thinking about the mechanical functions of their windows however they are thankful when they open and close quickly and keep outside air out and the inside air in. Sash windows can be costly to replace or repair in the event of problems. Fortunately, there are plenty of options to save money, without the expense of a new windows.

It is not uncommon for sash windows to become difficult to move as they've warped over years. This can happen due to moisture build-up and fluctuating humidity that causes wood to expand and contract at different rates. This can cause the sash over time to expand and turn discolored. It may also be difficult to close and open.
The first step is to make sure that the sash frame is in good condition. If the wood is rotten or sagging, and there is an abundance of moisture, this needs to be repaired before any other work can be done. This is a task for window specialists and can be quite costly.
The next step is to replace a pane of glass once the frame is examined. The sash can be left in place to do this, but it's more convenient to remove it and work on the table. Take out any glazing points, and then putty to hold the glass in place. It is essential to wear protective clothing during the procedure. The worker will then cut the new glass to fit, and then put it into the frame with the help of a special tool for glazing.
