Welcome to Peninsula Concrete Sealing, your trusted local experts for pressure cleaning services across the Mornington Peninsula. From Seaford to Red Hill and beyond, we specialise in transforming dirty, stained exteriors into pristine surfaces that enhance your property’s curb appeal and value.

Our high-pressure cleaning solutions tackle everything from driveways and patios and retaining walls, using eco-friendly methods tailored to the Peninsula’s coastal challenges like salt buildup, algae, and grime. Whether you’re preparing for sealing or simply refreshing your home, we offer bundled packages with our painting and sealing services for comprehensive results in Mornington, Langwarrin, Mount Martha, Rosebud, Rye and Carrum Downs.

Pressure cleaning is more than just blasting away dirt—it’s a technical process that requires the right equipment, techniques, and solutions to avoid damage to delicate surfaces. Many homeowners think it’s a simple DIY with a $100 Bunnings special, but improper pressure can etch concrete, stencil/oxide surfaces or strip paint, leading to further damage and costly rectification.

A key factor in successful pressure cleaning is understanding surface porosity and material sensitivity. Concrete, brick, and aggregate surfaces are porous, absorbing contaminants like oil, mold, and salt that embed deeply over time. This porosity makes thorough cleaning essential before sealing or painting, as residue can cause adhesion failure.

However, not all surfaces are suitable for high-pressure; painted wood, or soft stone like sandstone can be damaged by excessive force, leading to pitting or erosion. For instance, if your driveway is stencilled concrete with an oxide/stone finish, we adjust to low-pressure machine based methods to avoid surface stripping effecting the appearance.

A quick inspection determines the right pressure (typically 1,500-4,500 PSI for concrete, lower for oxide finishes), but a good rule of thumb is testing a small area. In close coastal suburbs like Dromana or Sorrento, where salt accelerates grime buildup, we use our tested chemical cleaning solution— we can use a mild, eco-friendly blend of biodegradable detergents and citric acid—to brighten and degrease without harsh solutions that could etch aggregate or kill grasses/plants.

Our chemical solutions penetrates pores, lifting embedded stains like such as organics, oil, or bird droppings, preparing the surface perfectly for our custom sealers. When cleaning over existing coatings or stains on exteriors, determining the type of residue is essential to avoid compatibility issues. Existing buildup could be oil-based stains, mold, or old sealers (acrylic, epoxy, or solvent-based), each requiring specific pre-treatment.

We start with a thorough inspection, using degreasers or solvent tests to identify the contaminant (e.g., oil dissolves in citrus-based cleaners, mold responds to antimicrobial solutions). DIY products like household bleach often do not do the job thoroughly enough, leaving residue that traps moisture and promotes regrowth in humid Peninsula conditions. For stubborn oil or graffiti, we apply targeted removers before pressure washing, ensuring a clean base. This prep prevents bubbling or re-staining, common pitfalls in salty air where contaminants accelerate degradation.

Once cleared, we rinse with low-pressure water to ensure all surfaces are free of chemicals. This prep step is critical, as inadequate cleaning will lead to uneven sealing or paint adhesion. Once prepped, we follow with our pressure cleaning, using adjustable nozzles for precision—wide machines for large driveways. For high-traffic areas like patios, we incorporate non-slip enhancers in follow-up treatments.

We are generally in and out within a 1-2 day process to minimize disruption. Surfaces can be walked on immediately after drying (1-2 hours, weather dependent), but avoid vehicle access for 24 hours to prevent tracking dirt.

The process is as follows:

Step 1: Assessment – We inspect the surface, discussing your goals and identifying sensitive areas or contaminants, ensuring the right pressure and chemical solutions.

Step 2: Preparation and Cleaning – We apply our tested chemical cleaning solutions to brighten and degrease, addressing issues like oil or mold with targeted treatments before pressure washing.

Step 3: Pressure Application – We use calibrated high-pressure equipment adjusting for surface type—gentle for oxide, robust for concrete—to remove grime without damage.

Step 4: Rinse, Cleanup, and Follow-Up – We rinse thoroughly, clean up debris daily, and return after drying to confirm results, your satisfaction, and bundle recommendations like sealing.

Beyond pressure cleaning, our expertise extends to various services. We seal exposed aggregate, paint garage floors with epoxy finishes, clean pool areas to remove algae, and treat pavers, bricks, patios, and retaining walls. For example, in Mount Martha, we pressure clean pool surrounds to combat chlorine buildup, while in Langwarrin, we refresh driveways with our chemical solution for pre-sealing prep.

We live by the saying “Do it right or don’t do it at all.” If we can’t guarantee an outstanding clean that withstands time, we won’t proceed. If there are reasons the outcome will not be a “10/10,” we will explain fully, leaving the final decision to you. We also ensure every project delivers value with a smile
