About Us

JJ Sweeney Limited is a specialist carpentry, joinery and fit-out contractor

Established in 1994, we have built a reputation for providing the highest standards of quality and service right across the construction industry, successfully delivering projects in the commercial, health, education, retail and refurbishment sectors.

We have formed strong relationships with a number of blue chip companies, including Balfour Beatty, Costain, Kier Group, and Skanska, and pride ourselves on securing repeat business by continually exceeding our clients' expectations.

With experience of working on prestigious projects such as The Queen's Gallery at Buckingham Palace, the restoration of Windsor Castle and the refurbishment of St Martin in the Fields in Trafalgar Square – to name but a few – our standard of workmanship is second to none.
