My name is Keith Sheehan, and I am the proud founder of BioSoft Powerwash. For over 30 years, I’ve worked in the Irish building industry — designing, constructing, and caring for homes. My career as an Architectural Technologist taught me not only the technical side of buildings, but also the importance of treating every property with the same care I would give my own.
From an early age, I was fascinated by how houses came together — how materials interacted, how roofs protected families, and how details as small as a joint or finish could determine whether a building lasted decades or centuries.
Over three decades, I have been involved in countless building projects across Ireland. This experience gave me a unique perspective: I don’t just see walls, roofs, or driveways. I see the story of a home, its structure, and its need for protection.
This perspective is what now drives my approach to exterior cleaning. For me, it’s not about blasting dirt away — it’s about preserving the integrity and history of every property, from modern homes to Georgian treasures.
During my years in construction, I saw a common problem: many exterior cleaning companies didn’t understand how buildings actually worked. Too often, high-pressure cleaning methods were used on delicate surfaces, leading to:
As a builder, I often had to repair this kind of avoidable damage. I knew there had to be a better way.
That’s why I founded BioSoft Powerwash — to bring a building-conscious approach to cleaning. Using softwash technology, I can clean properties safely, effectively, and with long-lasting results, all while protecting the materials that make up your home.
Unlike traditional power washing, softwashing combines low-pressure application with eco-friendly detergents that kill algae, moss, and bacteria at the root.
✅ Protects your building — no risk of cracked render, damaged roof tiles, or eroded mortar.
✅ Gentle on heritage homes — perfect for older or delicate properties, including Georgian buildings.
✅ Longer-lasting results — algae and moss are killed at the source, slowing regrowth.
✅ Reduces water damage risks — avoids forcing water into cracks, joints, or behind cladding.
