Carmarthenshire work means dealing with rural farmhouses and market-town stock with steady conversion and extension demand, and our surveyors specify accordingly rather than quoting blind.
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.
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.
