Keystone Water is one of Ireland's most trusted water filtration specialists — a focused, family-rooted business built on quality products and careful installations.
From a plumbing business to a water specialist.
Sean Blessington founded Blessington Heating and Plumbing in 2003. In 2008 he started fitting water filters — and demand took off.
As households kept asking for help with iron staining, hard water and well-water problems, Sean spun the filtration side out as a specialist company in its own right. Keystone Water partnered with some of the world's leading filtration suppliers — partnerships that still open doors today.
One thing has never changed: quality products and quality installations are the backbone of the business, and always will be.
