We ensure that no dust is left behind on your carpet or flooring meaning you have a less stressful move-in. We also ensure that any of your furniture items are out of the way for us to carry out our work safely and professionally.

How much does it cost to install a sash window?

The specific amount that it will cost to install your sash window will depend on many factors. The first determining factor will be whether or not you have double-glazing currently installed, as replacing an existing double-glazed sash window will be cheaper than installing a new sash window with double glazing.

How do you maintain a sash window?

It’s pretty much the same whichever type of windows you have, whether they be painted or unpainted windows, stained glass windows or an internal slider.

If there are parts missing then they need to be replaced or repaired. You may also need to repaint the window to get rid of any stains and revitalise the colours.

Should I repair or replTrade Timber Windows and Doors?
