If original windows are in relatively good condition it’s fair to expect an overhaul and draught proof to cost in the region of £200-£250 per window. In some cases external repairs are required such as sills or a new replacement sash that’s rotted away which can add to the cost.
Window sash replacements usually are not found in stock at home centers. These are special-order items from the manufacturer. In some cases, purchasing a new-construction window at your local home center, removing the sash, and using it as a replacement may be less expensive than ordering a sash replacement kit.
From the moment you purchase your window it will take anywhere between 4-6 weeks to build and manufacture your window for you. The actual installation itself could take anywhere between 3 hours to a full day.
One way to draught proof your sash windows is by using weatherstripping or timber/plastic beading. In keeping with the style of sash window properties the heritage timber beads are recommended. A better way is to call an experienced professional.
A window sash is the part of a window that moves and holds the glass panes together. The sash fits inside the window frame, which is attached to the house. The sash will vary slightly depending on the type of window. For example, on a double hung window there is an upper and lower sash that move up and down.
Tips To Help Maintain Your Sash Windows:
- Keep your windows clean. If you’re using paper towels to wipe the glass, you’re doing it wrong.
- Paint your windows regularly.
- Stop your windows from sticking.
- Maintain your windows insulation.
- Keep your windows safe.
- Oil windows for smooth operation.
- Regularly check your windows for rot.
- Reduce timber decay.
Loose glass is a common culprit of the rattling window. If the glass is loose, you will need to caulk it up. The Caulk will secure the glass and make it airtight so that no more rattling occurs. Apply the caulk to all cracks and edges of the window by using a putty knife to manoeuvre the caulk into tricky areas.
Start by removing the trim around the window. Remove the sash. Hold the cord to gently lower the weight, then cut and remove the visible sash cord. Access the weight, pulley, and the rest of the sash cord by removing the panel cover or window casing in the jamb. Remove any remaining pieces of sash cord.

A sash window or hung sash window is made of one or more movable panels, or “sashes”, that form a frame to hold panes of glass, which are often separated from other panes (or “lights”) by glazing bars).
Sash stops are fitted on the upper sash and this prevents the sashes from sliding over each other. Therefore, this prevents them from opening the window.
Use silicone spray or a beeswax polish to lubricate the sliding components. If the window starts to stick or squeak, NEVER use oil based products on your sash windows. Clean the outside pane of the top sash first. When complete, return the sash to a vertical position and then clean the inside pane.
