The promise
What the guarantee is
For 10 years from the date we finish the job, we guarantee the workmanship of the installation we carried out. If a fault appears that is caused by the way we fitted the unit, we come back and put it right at no cost to you. The guarantee is given by us, Forge Skylights Birmingham, directly, and it is set out in writing with your completion paperwork.
It applies to whichever option you choose. A fixed double-glazed rooflight and an electric triple-glazed lantern are fitted to the same standard and carry the same guarantee.
Covered
What the guarantee covers
- How the unit is fixed into the roof
- The weathering we install around it
- The opening and finish we form inside
- Fixing and fit: the unit, its kerb or upstand where we built it, and the way it is secured to the roof structure.
- Weathering: the flashings, seals and roof covering details we installed around the unit, so that water stays outside where it belongs.
- Structure we altered: trimming of joists or rafters we carried out to form the opening.
- Inside finish: the lining, boarding and plaster we formed around the opening, against cracking caused by our work.
Not covered
What sits outside it
- Faults in the unit itself, such as a failed sealed unit, a motor or a rain sensor. These fall under the manufacturer's own product warranty, on the terms the maker sets, and we help you make that claim.
- Damage from outside causes: impact, extreme weather events, fire, or work by other people on or near the unit.
- Parts of the roof we did not work on, and the general condition of the roof covering away from the unit.
- Normal wear and care: cleaning, decorating, and the routine upkeep the maker recommends.
- Moisture from inside the room, such as condensation from cooking or drying clothes, which depends on how the room is heated and ventilated.
