Repair or replace?
A new timber sash window usually costs several times what it costs to repair the one you have, before you add making good inside and out. If the box frame is sound — and in most Victorian and Georgian houses it is — repair is the cheaper and the more sympathetic option. We will tell you honestly when a window is past saving.
Frequently asked questions
Are these prices fixed?
They are our standard prices and what most jobs cost. The only one that genuinely varies is rotten timber, because it depends how much has to be cut out. Every job gets a fixed written quote after a free survey, and that price is what you pay.
Do you charge for the survey or the quote?
No. The survey is free, there is no call-out charge and there is no obligation.
Is VAT included?
No — the prices above are plus VAT.
Do you really beat any quote?
Yes, on a like-for-like basis: the same work, on the same windows, quoted in writing by an insured company, dated within the last 30 days. Send it over and we will beat it.
Do prices change for London?
No. The prices above apply across Kent, London and the South East.
Is it cheaper to do several windows at once?
Usually, yes — most of the cost of a single window is getting set up. We will price a whole house or a whole elevation as one job.
Quoted after a free survey
These three are priced per job rather than from the list above, because size and specification change the figure too much to publish a single number. Both are quoted in writing after a free survey, and the price promise applies to them as well.
