After the sash has been removed, disconnect the sash chains or cords and put it away in a secure location. Next, you'll need take the parting bead off the rail that connects the upper sash.

Make sure to protect the area surrounding it by covering it with plastic sheets.
After the sash has been cleaned by steam, it needs to be thoroughly dried and the glass's opening reglazed using new glazing compound. It is essential to use a high-quality glazing putty specifically designed for this type of work. If the weather permits, you can let it dry in a sunny and warm area.

The sash will be removed and the window's bottom sill will be cut off to gain access to the weight cavity.
After the sash is stripped, sanded and primed, it is ready to be installed. The sash is then glazed, and a new draughtproofing method is applied. This decreases the flow of air through the window, which increases thermal efficiency and eliminates rattles.
Water damage is a typical problem for sash windows. This is caused by the trapped moisture behind the glass. It can cause the wood expand, which can cause it to become brittle. A sash window that has been damaged by water can also show signs of rot. This is a serious issue and should not be ignored.
To prevent this from happening, we apply a chemical that is restorative to cleanse the glass and get rid of any mineral deposits. The chemical must be left on the glass for at minimum 30 seconds to penetrate the surface and remove any stains.
Then, it is cleaned using an agitating, soft cloth to get rid of any residue or dirt. After the primer has dried it is time to prime the areas to be painted and apply two coats of gloss. The varnish acts as a barrier to protect the wood to prevent moisture from causing damage to the wood beneath and making it easier to clean.

When repairing the team will meticulously remove the sash from the frame to access each component without further damage. The team will also cover the windows with protective covers and take out any knockouts not required to repair. Older windows typically contain lead paint that requires specialised techniques to handle. These techniques minimise the risk of dust dispersal, and also ensure the safety of the team.
