Driveways, paths, decks, patios, car parks and large concrete areas collect grime, moss,
algae and organic matter faster than most people expect. Left untreated, dirty surfaces look
neglected, become slippery and unsafe, and get harder to restore the longer they are left.
Blast Away Guys provides professional concrete and deck washing for homes and
businesses across Northland and Auckland. We use soft washing and pressure washing
depending on the surface, removing built up dirt, mould, mildew, algae, rust stains and
organic matter without causing damage.
Moss, mould, algae and organic matter break down surface materials over time, shortening
the lifespan of driveways, decks and paths. Wet organic growth also creates slip hazards,
particularly on driveways, steps and deck boards. Most surfaces benefit from a professional
clean once a year to stay safe, presentable and well maintained.
Not every surface should be pressure washed. High pressure water can strip sealants,
damage timber decking and pit softer concrete if used incorrectly. Our team assesses each
surface before starting and uses the right equipment and pressure for the job.
We use commercial grade equipment designed to clean evenly and avoid swirl marks or
streaking. For hard to reach exterior concrete walls and building facades, our long telescopic
attachments reach up to 15 metres high, so there is no need for a cherry picker and the job
gets done faster at less cost to you.
For larger commercial concrete areas, we use ride-on and wide area cleaning equipment to
cover more ground efficiently without compromising on the result.
The quality of a concrete or deck wash, and how long the finish lasts, can vary significantly
between companies. One of the biggest differences is what happens before and after the
wash.
Before we begin, we apply a biodegradable cleaning solution to the surface. This loosens
mould, algae and built up grime so that when we wash, we are removing it properly rather
than just pushing it around.
Once the wash is done, we spray on a biodegradable mould and algae treatment as part of
the same visit. This is what prevents streaking from appearing a couple of weeks later, which
can actually make concrete look worse than it did before it was cleaned. A lot of companies
skip this step, but we consider it as important as the clean itself, if not more so.
The treatment also continues to work after we leave. Concrete often ends up looking whiter
and brighter three to four weeks on, as it keeps breaking down any remaining mould and
algae spores on the surface.
Because we treat every surface as part of the same visit, the concrete stays brighter, cleaner
and streak free for months rather than weeks.
After washing, we apply a biodegradable mould and algae treatment to kill the spores at the
source. This stops mould from returning quickly and keeps the surface cleaner for
significantly longer than a wash alone.
Our business was built on care, reliability and making customers happy. Every quote is
backed by our Love Clean Guarantee: if you are not thrilled with the result and we cannot fix
it, you do not pay a cent.
We also believe in clear communication from start to finish. You will always know what is
happening, who is arriving, what is included, and what comes next.
Before each job, we send a short image rich profile of the team member visiting so you can
put a friendly face to the name and know a little about who is working on your property.
We take the time to explain your options in plain language so you can choose the solution
that best fits your property, goals and budget.
We service Whangarei, the Bay of Islands, and wider Northland, with Auckland services also
available.
Whether it is a single residential driveway or a multi level commercial car park, we provide
fast quotes and respond within one to two hours during business hours.
If possible, we recommend clearing the area of vehicles, planters, or outdoor furniture to allow for a more thorough clean. If there are any access issues or large items you need help with, just let us know ahead of time.
Yes. Our cleaning process removes organic build-up like moss and algae that makes surfaces slippery. After we’re done, your concrete will be safer to walk or drive on — particularly useful in shaded zones or before winter.
The post-wash mould treatment significantly slows down regrowth, so most surfaces stay clean for 6–12 months. Shady or damp areas may need more frequent treatment. Our goal is not just to clean the surface but to help it stay that way for longer.
Absolutely. We adjust the pressure, cleaning method, and detergent type based on your surface. This ensures decorative, stamped, or coloured finishes are not damaged. We’ve cleaned everything from exposed aggregate to dyed driveways with excellent results.
Yes. Our high-powered concrete-safe process is effective at lifting black mould, green algae, moss, and even stubborn tyre marks. For oil stains or heavy discolouration, we use specialised degreasers where needed. You’ll see a brighter, more even surface with improved safety and presentation.
We professionally clean concrete driveways, footpaths, patios, and paved areas using commercial-grade surface cleaners and pressure washing equipment. This removes years of built-up grime, mould, and organic material. After cleaning, we apply a mould treatment that continues working for weeks, helping to keep your surfaces looking better for longer.
