Friendly, Reliable & Building-Smart Exterior Cleaning in Cork
When you hire someone to clean your home, you want two things: a incredible transformation and complete peace of mind that your property is in safe hands.
Hi, I’m Keith Sheehan, founder of Biosoft Powerwash®. Before setting up Biosoft, I spent over 35 years in the Irish building industry as an Architectural Technologist and builder. I’ve designed, built, and cared for hundreds of homes across Cork.
That experience gives our team a huge advantage when cleaning your property. We don't just point a hose at a wall—we understand how your home was built, what materials we're working with, and exactly how much pressure or treatment to use.
From heavy-duty driveway power washing to gentle house softwashing, we deliver a 5-star finish every single time.
Protecting Your Property with Architectural Knowledge & Family-Run Care
As a local Cork business led by Keith Sheehan—an Architectural Technologist with over 35 years of construction experience—we treat your home with the care and expertise it deserves.
Rather than using high pressure on every surface, we match our cleaning method to your property's specific materials. That means your home gets a dramatic visual transformation while protecting wall renders, roof tiles, and garden paving for the long haul.
Render & House Walls: Gently removing red algae (Trentepohlia) and dark streaks using low-pressure softwashing that sanitizes without stripping paint or cracking plaster.
Roof Tiles & Slates: Clearing moss, lichen, and biological spores at the cellular level so your roof stays clean 3 to 5 times longer—without stepping on or breaking tiles.
Driveways, Patios & Paths: Calibrated power washing for concrete, block paving, tarmac, and natural stone to lift embedded grime, weeds, and oil stains.
Gutters & Downpipes: Clearing heavy silt and blockages using high-reach carbon-fiber vacuums to keep your rainwater systems flowing freely and prevent damp walls.
Windows, Frames & Soffits: Pure-water reach-and-wash systems that leave glass, sills, and fascias spot-free and streak-free.
Whether you need a targeted driveway restoration or our Gold Standard Full House Clean, Keith deals with you directly to deliver 5-star results every time.
