As spring approaches and the weather warms up, it’s a great time to start preparing your property for the barbeques, backyard soccer and gatherings with friends and family. During the winter months, rain, cooler temperatures, shade and reduced airflow can leave exterior surfaces damp, stained and slippery. Roofs collect leaf litter from the autumn falls, gutters fill with debris, footpaths and stairs become slick and walls, windows and outdoor furniture often carry a film of grime that’s easy to ignore.
That’s why spring maintenance is more than a cosmetic clean-up. It protects the value of your property. When done properly, it helps protect surfaces, reduce slip risk, improve presentation, and slow the return of mould, algae, and other organic growth. The key is to inspect first, clean in the right order using the right method, and apply preventive treatments where needed. Chemron specialises in custom chemical formulation and provides cleaning chemicals to ensure your property is ready for the new season.
Inspect Before You Clean
Before you pull out a pressure washer or start applying surface treatments or cleaning products, simply walk around your property and inspect each area carefully. A quick inspection helps you identify problem areas, choose the right cleaning methods and avoid damaging surfaces that need a gentler approach.
What to look for:
- Algae: Look for green, black or brown staining on footpaths, walls, pavers, shaded garden beds, retaining walls, outdoor steps and around areas with poor or frequent drainage. Pay extra attention to areas that receive low sunlight.
- Mould: Check damp areas, corners, rendered walls, eaves, ceilings, timber, grout lines and surfaces that receive little sunlight. Most common on southern-facing aspects with low sun exposure.
- Rust and Oxidation: Inspect painted metal, powder-coated surfaces, gutters, fascias, roller doors and outdoor furniture for chalky residue or faded finishes.
- Blocked gutters: Look for leaf build-up, overflowing downpipes, sagging sections, water marks on walls and plant growth inside gutters. Clean gutters are very important as we move into the warmer months; removing debris from your roof and gutters dramatically reduces bushfire risks.
- Slippery paths: Pay attention to shaded concrete, tiles, brick, pavers, timber decking and any area where water sits after rain.
Don’t assume all staining is the same. Organic growth, mineral staining, rust, oxidation and dirt may look similar from a distance, but they often require different treatments. Using the wrong approach can waste time, money and even make contaminants harder to remove from porous surfaces. The wrong product or method can damage sensitive surfaces or leave them looking worse than before you started, so it’s best to talk to an expert if you’re unsure.
Clean in the Right Order
A good spring clean works from the top down. If you clean footpaths or windows first and then wash the roof, gutters or walls, the dirty water and debris will run over the areas you’ve already finished. A proper cleaning sequence saves time and delivers cleaner, more cost-effective results.
A professional sequence:
- Roof: Remove loose debris, check for any moss or lichen and make sure the roof surface is suitable for the chosen cleaning method.
- Gutters: Clear leaves, soil and any blockages so rinse water can drain freely.
- Walls: Wash exterior walls, eaves, fascias and high surfaces before moving lower.
- Windows: Clean glass, frames and tracks after the upper surfaces have been washed.
- Paths: Treat and clean driveways, entries, stairs, ramps, decks/patios and walkways once runoff from above has finished.
- Outdoor furniture: Clean tables, chairs, umbrellas and storage boxes after surrounding surfaces are clean.
- Final rinse: Rinse away residue, loosened debris and any overspray so the property is left tidy and ready to use.
Quick Tip: A lot of houses have Reverse Osmosis (RO) water filters for drinking water. Using this to clean windows will help achieve a streak-free finish.
Cleaning in this order makes the whole job easier and helps protect your surfaces along the way. For example, once gutters are clear, you can better control where water flows. Once walls are clean, you can see whether any of the remaining marks are stains, oxidation or damage. Once you’ve cleaned a footpath, you avoid dragging grime back across high-traffic areas like decks and patios.
Don’t Just Pressure Wash
Pressure washing can be an excellent way to remove visible dirt, grime, algae, mould and slippery build-up from hard exterior surfaces. It restores a clean, fresh appearance quickly and can make driveways, footpaths and paved areas safer to walk on. But pressure alone isn’t always enough.
The problem is that high-pressure water often removes only what you can see, without fully treating what remains in the surface. Spores and organic matter can sit in tiny pores, cracks, grout lines, render, concrete, timber or stone. If the surface stays damp or shaded, growth can return quickly.
There’s also a risk of using too much pressure. Aggressive washing can etch and permanently mark concrete, strip paint, lift render, damage timber fibres, force water behind cladding or disturb older coatings. Delicate surfaces often need lower pressure. Soft washing using the correct chemical treatment, with a controlled dwell time and a thorough rinse, is often the better approach on sensitive surfaces.
Protecting Surfaces After Cleaning
Once surfaces are freshly clean, that’s the ideal time to apply surface protection and prevention strategies. Preventive treatments can help slow the return of mould and algae, reduce water absorption, improve cleanability and extend the life of surfaces exposed to weather.
- Anti-mould and anti-algae treatments: Target remaining spores and help reduce regrowth on damp or shaded areas.
- Water-repellent treatments: Help porous materials shed water rather than retain moisture, reducing conditions that encourage mould, algae and other organic growth.
- Sealers: Protect concrete, pavers, stone and other suitable surfaces from staining and moisture ingress.
- Protective coatings: Help preserve painted, coated or metal surfaces where appropriate.
- Routine maintenance plan: Once clean, a simple, quick maintenance plan helps keep high-risk areas under control before they become larger, more time-consuming cleaning jobs.
The best treatment depends on the surface, exposure, drainage, surrounding vegetation and the type of contamination present. A shaded concrete path may need a different approach from a sandstone retaining wall, painted exterior cladding, outdoor tiled patio or treated timber garden bed. If you’re ever in doubt, seek advice on the method and treatment.
Don’t Forget Your Equipment
Spring maintenance isn’t just about the property. It’s also the time to check and service the equipment you rely on for cleaning, treating and maintaining surfaces. Equipment that’s been stored through winter may need inspection, servicing or cleaning before use.
- Pressure washers: Check hoses, seals, trigger guns, nozzles, filters and water flow before starting. Use the correct nozzle and pressure for each surface.
- Garden tools: Check oil and fuel in power equipment, blades, handles and pivot points for damage or rust.
- Sprayers: Inspect tanks, wands, seals and spray patterns. Flush old residues well and clearly label all chemicals. Where possible, use different sprayers for different product classes, e.g. avoid using the same sprayer for weedkillers and liquid fertilisers.
- Floor scrubbers: Check brushes, pads, squeegees, batteries, tanks and recovery systems before cleaning hard floors or covered outdoor areas.
- Storage: Store products upright, away from heat and direct sunlight, and keep equipment clean, dry and ready for the next job.
A little preparation prevents delays and expensive repairs, reduces waste and helps products and equipment perform as designed. It also improves safety, especially when working with concentrated cleaning products, slippery surfaces, powered equipment or elevated areas.

Walls and eaves | Dirt, grime, mould, algae, oxidation, staining | Wash gently and treat affected areas |
Windows | Dust, water marks, tracks, frames | Clean after roof, gutters and walls |
Paths and driveways | Dirt, grime, slippery growth, staining, pooling water | Clean, treat and improve drainage where possible |
Outdoor furniture | Mould, dust, bird droppings, fading, loose fittings | Clean, rinse and dry before regular use |

Final Thoughts
Spring maintenance is most effective when it’s planned, sequenced, and matched to your environment. Start with an inspection, work from the roof down, avoid relying on pressure alone, and finish with the right protection. This approach gives you a cleaner property now and reduces the risk of rapid regrowth during the warmer months.
