Preserving Legacies with Precision

Our Story:
The Journey of Hennessy Ward

Hennessy-Ward was born from the need to find a safe, cost effective and environmentally friendly way to restore the façades of heritage buildings whilst causing no harm.

Over 10 years ago Orla Hennessy and David Ward embarked on this journey by removing biomass and the associated staining from residential buildings.

From the outset they were committed to only using the best available products and methods. Above all, do no harm was and still is their guiding philosophy.

Before long, their commitment to quality, integrity and professionalism set them apart and brought them to the attention of professionals responsible for the care and maintenance of historic monuments and heritage buildings.

Tasked with the responsibility of cleaning these legacy buildings, the S.A.F.E.R. System was developed and Hennessy-Ward was created.

Today, with years of experience under our belt, our journey continues. We’ve expanded our services, adopted the latest in eco-friendly cleaning technology, and trained a team of experts who carry forward our legacy with the same passion that sparked this venture.

From our humble beginnings to our position as industry leaders, the Hennessy-Ward story is a testament to dedication, innovation, and an unwavering love for heritage.
