Our 10-year draught-proofing guarantee
Draught-proofing is guaranteed for 10 years. Every other repair, restoration and glazing job is guaranteed for 1 year. Here is exactly what that covers — and what it does not.
Draught-proofing carries a 10-year guarantee. All our other workmanship — joinery, timber repairs, cords, glazing and finishing — is guaranteed for 1 year. Both run from the day the job is signed off, both are written into your quote, and both stay with the property.
What each guarantee covers
- Draught-proofing — 10 years on the seals, the re-balancing and the way the sash runs
- Joinery and timber repairs — 1 year on splices, new rails, sills, stiles and horns
- Sash cords, pulleys, weights and the balance of the window — 1 year
- Glazing we have installed, including slim double glazed units — 1 year
- Paint and finishing we have applied as part of the job — 1 year
- Secondary glazing and new sashes we have made and fitted — 1 year
What it does not cover
So that there is no argument later, these are the things a workmanship guarantee cannot sensibly include:
- Accidental damage, break-ins and storm damage
- Timber we advised should be replaced and were asked to leave
- Work altered or re-painted by someone else afterwards
- Normal seasonal movement in timber, which every window does
- Parts of the window outside the scope we quoted for
And the rest of it in plain terms
