About Us
Joinery Boys Ltd is a bespoke joinery company based in the heart of Sussex, specialising in high-quality timber work for both interior and exterior projects.
The business was founded by William Hobbs, whose 20 years' experience combines traditional joinery principles with modern materials to produce work of exceptional quality and precision.
In 2026, William was honoured with the City & Guilds Master Joiner Award, recognising the highest standards of skill and workmanship within the trade.
The City & Guilds Master Certificate in Carpentry and Joinery is one of the highest honours within the trade. Awarded to craftsmen with extensive experience, advanced qualifications and a commitment to mentoring, it recognises exceptional skill, knowledge and dedication. The scheme is supported by the Worshipful Company of Joiners and Ceilers, with the award formally presented by the Lady Mayor at Mansion House in the City of London — marking a significant achievement within the industry.
Proud to be a Fellow of the institute of Carpenters.
From kitchens, wardrobes and studies to staircases, windows and doors, every project is different, carefully considered, designed and produced with close attention to detail.
We work closely with homeowners, builders and architects, taking pride in delivering thoughtful designs, clear communication and joinery that enhances the character and quality of a home.
All our work is produced in our East Sussex workshop using carefully selected materials and traditional joinery techniques, ensuring the finished result is both durable and suited to the property to stand the test of time.
Joinery Boys are delighted to have been selected as an approved manufacturer for Accoya Wood.
What is Accoya Wood?
Accoya modified wood has become the benchmark in the timber industry for performance and sustainability. No other wood offers the same combination of durability, stability, and versatility. Sustainably sourced and with a low total lifetime carbon cost, Accoya actively contributes to a circular, bio-based economy and is one of the few truly sustainable building materials available.
In this video, we take a closer look at the groundbreaking science behind Accoya wood. Through a precise acetylation process using acetic anhydride – combined with carefully controlled heat and pressure – we increase the moisture-resistant acetyl groups and reduce the water-attracting hydroxyl groups. This unique, patented technology transforms fast-growing, sustainable wood into an ultra-high-performance building material.
Unrivalled Benefits
Accoya high-performance modified wood has been chosen for its exceptional quality in widely varying environmental conditions around the world. Thorough real-world testing has been conducted over many years on this long life wood which means we can confidently provide industry-leading warranties of up to 50 years.
