Weather Stripping
Weather stripping is a thin, flexible strip of material used to cover the edges of doors and windows when they are closed. It keeps out the outside air and the contaminants it contains. It prevents drafts from passing through the gaps, making your house too cold or letting noise from outside in. You can buy ready-to-use weather stripping in rolls of 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. Do the same between the upper and lower sashes. Additionally, you can install the same strips on the side of the frame to prevent rattling.
Weather strips are required on both sides of double-hung windows. You may also need to put strips inside the frame towards the bottom. The strips stop the window from snapping shut, and they also stop dust and insects from blowing through the gap between the sash and jamb.
Before putting in the weatherstripping, clean the frame of the sash with mild soap and warm water. Dry it using a soft cloth. A utility knife can be used to remove any caulk and paint from the interior stops. Use a putty knife to protect the frame and take care to pry the stops away. Replace the weather stripping.
The new weather stripping should be flexible enough to allow for the sash's movement, but sturdy enough to remain in place when closed. Adhesive-backed foam tape is a common choice. It is easy to use and is available in various thicknesses. Door sweeps are available in a variety of sizes and types, and can be used on any type of window and doors.
Compare the metal tabs of the new sash to those on the old sash prior to you install it. If window repairman are a different shape they won't fit into the the frame of your window correctly, and you'll have to remove the sash and start from scratch. The good thing is that individual sash replacements aren't expensive, so total window replacement won't be a costly disaster.
Sash Cords
Start by removing the outer parting bead - the thin pieces of wood that divide the inner and outer frame. You may find they're nailed to the frame however a hammer and nail set will do the trick. Make sure you lay down a tarp because sash windows are messy and you'll be causing damage to paint and possibly rotting wood, particularly in older homes. Also wear a mask, because dust can contain lead.
Then, remove the upper cord and sash. If you're not putting new cords in, cut the old ones, and tie them so they can't be pulled through the holes in the sash. If you're replacing them, take off the nail that holds each cord to the sash. Then, remove the nails that secure each cord to the sash. If the pockets on either side of the frame are still in place, prise them out with the hammer and nail set, or with a crowbar. You may also need to scrape off some of the old sash material.
When the pockets are empty and you're able to remove the sash's outer layer and be aware of the channels on either side of the frame, where the cords of the sash run. If you're installing new sash cords, opt for cotton ones. Cotton ropes last longer than synthetic cords, which stretch and slide. You'll also have to ensure you have the right amount of weight for each sash. You can weigh them on a kitchen scale to make sure however, the weights should be approximately half the size of the sash.
Reset the tilt pin, if it's still in its position. To do this, you'll have to raise the lower sash a little. Be cautious not to let it drop. Lock the pin. Finally, put in the new sash balance (the tube that holds the weights) and you're done! Make sure to verify the tilt pin, and lock it back onto the upper sash.
Parting Beads
The parting beads (vertical strips of wood holding the lower sash) and staff bead are an integral component of a sash window. They help in the retention of sash window weights, stop water ingress, and form a seal between the inner and outer boxes. They can cause excessive draughts and rattle if they are damaged or in poor condition.
Use a sharp knife to cut through any paint junction between the parting beads and the box window frame. Carefully pull the parting beads out of their narrow grooves. They are designed to be a snug fit but may have been nailed in place, so check for screws or nails. Take off any sash cords that were nailed to the wall.
After removing the parting bead and the parting bead, you can remove the lower sash from both sides and remove the meeting bar (which overlaps with the bottom sash of a double-hung sash). The meeting rail can be lifted out of the frame, allowing you to see 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 are having difficulty closing or lifting the window, it may be worth looking at alternative sash balance systems. They are discussed in a separate article.
To make the windows of the sash weatherproof apply draught strip and paint (with a high-quality oil-based primer). You can also smooth the surface to smooth it and then apply a multi-purpose mastic. Apply a small amount 'fronting putty' to the area where the glazing rebates meet the internal sash upstand. In the front of the putty with a fillet to create an even edge. Finish just a few millimeters below the sightline. Replace the sash cords, tie the knots if necessary & hang the window again. Think about using white braided marine rope or cord since it lasts longer than the cheap cords that stretch over time. This will also reduce the opening distance of the sash window making it easier to close.
Glass
Most homeowners don't spend much time thinking about the mechanical functions of their windows However, they are happy when they open and close with ease and keep outside air out and the inside air in.

Draught-proof strips are also available to increase the efficiency of your energy use and decrease noise pollution.
A lot of times, sash windows which are difficult to move up and down aren't just stuck, but have been damaged over time. This could be because of the build-up of moisture and changing humidity, which causes wood to expand and contract at various rates. This can cause the sash to swell and become discolored. It may be a challenge to open and close.

If there is an abundance of moisture and the wood is rotting or sagging, it's going to require repairs before any other work can be completed. This is a pricey job that should be handled by professional window contractors.

After that, the worker can cut new glass to the size required and install it in the frame using a glazing Hammer. It is important to use the proper tools for cutting glass due to its toughness and that it is prone to shattering or cracking.
