Exterior Cleaning

Irish weather leaves its mark on the outside of a house: green algae on render, black streaks under the sills, grime on fascias and soffits. We wash it off with the right method for each surface, using a gentle soft wash on render and painted finishes rather than blasting them with high pressure.

What's included

The full job, not half of it.

  • Soft washing of render, pebbledash and painted walls
  • Fascias, soffits and gutter fronts cleaned
  • Windowsills, door surrounds and porches
  • Treatment that kills algae at the root so it stays away longer
  • Surrounding plants and windows protected and rinsed

Time to book if you've got

  • Green or black patches on the render, usually on the shaded side
  • Streaks running down from the windowsills
  • Fascias and soffits looking grey instead of white
  • The house looking tired next to freshly painted neighbours

How we do it

Step by step.

  1. 01

    Assess

    We check what the walls are made of and how they're finished, because that decides the method.

  2. 02

    Protect

    Plants, windows and anything delicate gets covered or rinsed down first.

  3. 03

    Soft wash

    A low-pressure clean with a treatment that breaks down algae and grime without damaging the surface.

  4. 04

    Rinse

    Everything rinsed off and the area left tidy.

Best time to book

Spring to early autumn, ideally in a dry spell. Done before you paint, it gives the new paint a clean surface to grip.

Exterior Cleaning: your questions

Will power washing damage my render?

High pressure can, which is why we don't use it on render or painted walls. A soft wash does the cleaning with treatment, not force.

How long does it stay clean?

It depends on how much shade and rain the wall gets, but because the treatment kills the algae rather than just rinsing it off, it comes back much more slowly.

Should I clean the walls before painting?

Yes. Paint over algae and dirt doesn't bond properly and starts to fail early. A wash first is the cheapest way to make a paint job last.
