C A Duquemin Ltd are one of Guernsey’s longest established building companies and we have been trading since 1924.

We specialise in historic and high-class refurbishment building works, although we also carry out a large amount of new build projects. We currently have a staff of over 60 full time craftsmen and we carry out all traditional building trades in house. We also have our own fully equipped joinery workshop for the manufacture of bespoke joinery such as windows, doors and staircases, and a minor works team who carry out building works from £50 to £50000. We are happy to advise and quote for any building works, no matter how small.

We are able to advise clients on the best procurement routes suited to their particular building project and we also offer a free advisory service.

Our reputation for quality and experience is reflected by the amount of repeat business that we generate.
