Like much of Durham, Seaham features colliery terraces and stone market towns with growing extension and conversion demand. It's the kind of work our surveyors and fitting teams handle week in, week out across the North East region.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Coverage takes in Seaham, Bishop Auckland, Consett and Chester-le-Street and every corner of Durham. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
When the frame itself has failed: non-thermally-broken early aluminium running with condensation, or softwood gone soft. We'll tell you straight on survey and price both routes.
Yes — misting means the sealed unit has failed, not the lantern. We measure the pane, manufacture a matching unit (including self-clean or solar coatings) and fit it in situ, usually within a couple of weeks.
Could be five things: ridge capping, hip junction, perimeter seal, kerb flashing or the flat roof itself, with condensation a sixth impostor. We trace the actual path before quoting, so you pay to fix the real fault.
Yes — repairs cover all major aluminium, uPVC and timber systems regardless of who installed them. Photos of the lantern and the fault speed up the first visit.
Yes — Seaham is inside our standard Durham coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Seaham on dedicated glass transport.
Stocked standard sizes typically deliver to Seaham within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
