Who We Are

Based at Townsend Enterprise Park, Townsend St, Belfast BT13 2ES, Diamond Property Maintenance NI is a trusted name in roof cleaning, pressure washing, soft washing, gutter maintenance, and more. Our time-served tradesmen are not only experts in their craft but are also PASMA and IPAF-trained, ensuring every job is completed safely and efficiently.

DPMNI is not just a business venture for us; it’s a reflection of our shared values and vision for the future. As partners in both life and work, we started this venture with little knowledge of property management.

  • Tristan brings 20 years of experience in site fitting and business management, having worked across the UK and Ireland.
  • Christina has 17 years as a Youth and Community Worker, supporting socially disadvantaged areas and advocating for positive change.

Through research and development, we made it our mission to become one of Northern Ireland’s leading property and facilities management companies.

We want our children to grow up in a world where they can appreciate the spaces around them and take pride in knowing their parents created that. Through DPMNI, we strive to set an example of hard work, integrity, and dedication, showing our kids the importance of pursuing their passions and supporting them in reaching their goals.

We also recognise that the choices we make today will shape the future for our children. By prioritising an eco-friendly business, we aim to leave a legacy they can be proud of.

We want our clients to see us as more than just service providers. We are young entrepreneurs from two different communities in Northern Ireland, striving to show a better way of life.
