About us

Craftsmanship, built on relationships.

Based in Guernsey, we combine skilled trades with a personal, hands-on approach — delivering results that last.

Our story

A Guernsey business, built the right way.

D.Alderton Carpentry & Construction started with a simple idea: run a building company the way a client would want one run. Skilled trades, tidy sites, honest pricing, and a person who answers the phone.

Fifteen years later, we deliver bespoke carpentry, joinery and full-scale construction across Guernsey — from private kitchen renovations to café fit-outs, luxury home extensions and the refurbishment of the Lihou Island House.

We stay deliberately small so we can stay hands-on. Every project has a lead you know by name.

Our approach

Understand first. Build with care.

We take the time to understand your goals before we begin — the constraints, the ambitions and the details that matter.

Every project, big or small, receives the same level of craftsmanship and respect.
