From Seaham kitchen extensions to full orangery builds, our roof lantern installation service covers supply-only delivery and complete installation throughout Durham — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
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, Durham, Darlington and Hartlepool and every corner of Durham. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Yes — our teams cover England, Wales and Scotland. Distance affects scheduling more than price; we'll give you the next available slot for your postcode when you enquire.

A standard domestic lantern on a ready kerb is a one-day job including sealing and trims. Cut-ins to existing roofs, oversize lanterns or plastered reveals extend that to two days.
A finished kerb to the dimensions we issue, the roof membrane dressed over it, and clear access for glass — which for larger panes can mean two fitters and lifting equipment we bring.
Yes — installation is available across Seaham and Durham, and if you'd rather buy supply-only, kerbside delivery to Seaham is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Seaham usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
