About Rihoy & Son


I can recommend their service and quality.

Charles Billson, chairman of Long Port Group
Royal Terrace apartments.

We commissioned Rihoys to do internal and external works to our property. They were efficient and completed the works with minimal disruption to our lives. They also came in on time and budget. We can highly recommend the project management skills of Dan Taylor who was a pleasure to work with.

The project was delivered under strict time constraints, with a number of essential sub-contractors and design specialists and changing requirements as the project evolved.

“Dave Tostevin was instrumental in delivering this project and his considerable efforts in programming and organising the works is, in my view, a major factor in delivery.”

Ross Paisley

I would like to congratulate all on the hard work and excellent quality of workmanship achieved on this project.

The project was completed on time and on budget and that is a significant achievement for which you and your company should be very proud of.

Our History

Originally established by John William Rihoy in 1924, the company started working exclusively for the horticulture industry, building and maintaining glasshouses.

The business diversified after World War II when John, affectionately known as Jack, constructed his first carpenter’s shop behind the family home in the Ville Baudu, Vale.

From 1950 until 1990, John Rihoy jnr, Jack’s son, made the business his life's work and took it forward to become one of the most successful building contractors in Guernsey.

In 1958, Rihoy & Son relocated to its current home at Sandy Hook, L’Islet. The business has expanded its operations significantly to include the construction of new housing, domestic extensions, refurbishment, major projects for the finance, hotel and tourist trade, the industrial sector and the States of Guernsey.

The company’s chairman, Jeremy Rihoy, and managing director, Gavin Rihoy, are third generation Rihoys working for the privately owned family company.
