Maintenance and repairs

Sash and case windows can usually be repaired with relative ease, and regular maintenance will prolong their life by many years.

Modern timber can rarely match the quality and durability of the slow-grown softwoods originally used to make these windows. So it’s best to retain as much of the existing timber as possible wherever repair is required.

Repairing timber decay

New timber can be spliced in to replace areas of localised decay. But care must be taken to select compatible wood with similar qualities to the original. Severely rotten windowsills may need to be replaced completely using new matching timber, or sometimes just the front part may need to be renewed (half sill repair). See more on repairing or restoring sash and case window shutters.


External and internal window paintwork must be kept in good condition to protect against the effects of weather on the outside and condensation inside. Windows usually need external repainting every five years, depending on exposure and the paint manufacturer’s guidelines.

Painting of the sashes and case must follow a particular order to avoid sealing the window shut. Sash and Case Window Repairs Stirling.

Paint removal

Paint layers that hinder the window’s operation can be removed using a number of methods. Care must be taken to avoid damage to timber, glass, putty and surrounding masonry whichever option is used.

Replacing sand mastic

Traditional mastic made of a mix of burnt sand and linseed oil is a long-lasting, durable material and is still readily available. The seal can occasionally be repaired, but when split or partially missing it should be replaced, cutting out the defective mastic and replacing entirely.

Replacing sash cords

Cotton sash cords and braids will become worn over time and require renewal. This is best done before the cord breaks. See more on re-cording sash and case windows.

Replacing glazing

Only original glazing that is missing or beyond repair should be replaced, as many types of traditional glass are no longer produced in the UK. Replacement glass should match the original as closely as possible. Salvaged glass may be an option, and replica cylinder glass is also available.

Repairing broken ironmongery

You should aim to reuse surviving original ironmongery such as cord clamps, sash lifts and sash fasteners, which are usually of a very high quality. Broken ironmongery can often be repaired. Paint can be removed fairly easily where it has hidden or impeded the use of ironmongery. Reproduction fittings can be used if original ironmongery is missing or beyond repair. See more on replacing ironmongery on your sash and case windows.

Extra sash locks can be fitted to the meeting rails to improve security of the window when closed. Timber blocks and/or sash stops can also be fitted to restrict opening beyond a certain point.
