HIGH RISE MAINTENANCE GUIDE

Why Building Facade Cleaning Matters on a High Rise

Building facade cleaning is one of the simplest ways to protect a high rise. Over winter, Perth facades collect dirt, mould, pollution and, closer to the coast and the river, salt. Left on through a hot summer, that grime bakes onto paint, render and glass, stains the building and wears the coating faster.

A wash before summer resets the building and gives you a clear look at the facade while the crew is on the ropes. These are the signs your building is due:

TIMING, METHODS AND FREQUENCY

How Often to Wash a High Rise and How It Is Done

A building wash is not just about looks. Dirt and mould hold moisture against the surface, salt attacks paint and metal, and a dirty facade hides the cracks and failed sealants you want to catch early.

Why wash before summer?

  • Winter grime comes off easier. Mould and dirt are softer after the wet months than after a summer of sun has baked them on.
  • The coating lasts longer. Clean paint and render handle heat and UV better than surfaces carrying a layer of grime and salt.
  • It sets up the rest of the year. A clean building is the right starting point if you are planning window cleaning, repairs or a repaint.

How often should a high rise building be washed?

It depends on how exposed the building is. Paint makers publish their own maintenance advice, and it is worth following because most paint warranties depend on the coating being maintained as instructed. Dulux, for example, recommends washing painted surfaces every year in sheltered and inland areas, and every 6 months in coastal and industrial areas. Check the maintenance conditions for the paint system on your building, and plan washes around them.

Pressure washing or soft washing?

Not every surface can take a high pressure blast. Hard surfaces such as concrete and masonry can usually take higher pressure, while painted render, cladding, sealants and glass need a gentler soft wash, with lower pressure and the right cleaning solution doing the work. A good crew matches the method to each part of the building rather than using one setting for the lot.

How a high rise facade is washed by rope access

  1. Roof anchors are tested. Every rope access job starts with anchors that are in date and safe to use.
  2. The drops are planned. The building is split into drops, and residents are told when to keep windows and balcony doors closed.
  3. Work runs top down. The crew washes from the roof down so dirty water never runs over a clean section.
  4. Entries and footpaths are protected. Areas below each drop are managed while the work is under way.

Combine the wash with windows and a facade check

While the crew is on the ropes, it makes sense to do more than one job. Up2 Rope Access can wash the building, carry out high rise window cleaning and report anything that needs attention, such as cracked concrete, rust staining or failed sealants, which are early signs of concrete cancer. Our high rise building washing by rope access covers apartment, strata and commercial buildings across Perth, including coastal suburbs like Fremantle.

Building Facade Cleaning Questions From Building Managers

It depends on exposure. Paint makers set their own maintenance advice; Dulux, for example, recommends washing every year inland and every 6 months in coastal and industrial areas. Buildings near the coast or the river usually need washing more often.

Most paint warranties depend on the coating being maintained as the manufacturer instructs, and regular washing is usually part of that. Check the warranty terms for the paint system on your building.

High pressure can damage soft or painted surfaces and sealants. Those areas need a soft wash with lower pressure and the right cleaning solution, while hard surfaces like concrete can usually take more pressure.

Yes. We can wash the building and carry out high rise window cleaning in the same visit, so the crew only sets up once.

Mainly keep windows and balcony doors closed on the side being washed. We plan the drops with your building or strata manager so residents know when each side is being done.
