As a family-owned, independent business, we ensure our clients receive personalised experiences and premium results.

We are your trusted, high-quality local tradesman.


When you work with Diligent, you’re guaranteed bespoke service from inception and design to completion. Our expert and highly qualified team has the niche knowledge to assist you throughout all aspects of your project. Unlike other joinery companies, we don’t use third-party contractors. Instead, we’re by your side every step of the journey.

The three key elements of any successful project are time, quality, and cost. Diligent is committed to delivering these elements through professional project management, regular updates, and quality assurance.

Building projects and refurbishments can be a stressful experience. Diligent is here to provide unforgettable, bespoke results and stress-free delivery.
