Good to know


What areas do you cover?

We cover South and South East London.

Can you replace broken sash cords?

We are able to change sash cords. Our sash cord repair service includes replacing all 4 sash cords – even if only one is broken.

Do you replace broken springs / spiral balances?

Some sash windows have spiral/spring balancers instead of sash cords and weights. These are made up of a plastic tube and a metal torsion spring.
Spiral balancers do fail and need to be replaced in order for the window to function correctly. These spiral balancers are made up according to the size and weight of a particular sash. For Sash Smart London Ltd to supply a suitable replacement we would need an initial visit to measure and order the correct size spiral balancers. This service normally takes a couple of days from point of order.

I have single glazed sash windows, can I replace these to double glazed sash windows?

Yes, It is often possible to change just the sashes (the parts that move up and down) from single glazed to double glazed without replacing the complete box frame. Alternatively the window can be fully replaced which would then be double glazed to comply with building regulations.

I understand there are different types of double glazing can you help explain the differences?

Not all double is glazing is the same and some provide more thermal insulation than others. We will happily talk you through the various options and benefits of differing glass.

CERTASS or FENSA registered?

I would like to completely replace my windows, how long does it take?

This will depend on the quantity and size of the window, but as a general guide one window can be replaced within a day. In most cases your required work would take 2-3 days we never leave you with a window out and always leave your property vacuumed before we leave.
