Some driveways in Invercargill seem locked in a never-ending war with the weather—one rainy week, and they’re streaked with moss, tire marks, and stains no one remembers making.

Standard cleaning tools don’t do much. A broom just pushes the mess around, and even pressure washers fall short without the right technique or equipment.

For anyone tired of pretending the mess “isn’t that bad,” this list is a lifeline. These Invercargill driveway concrete cleaning pros know how to handle the grime—and they’ve got the gear to back it up.

1. I-Clean

What we like about I-Clean is how much they’ve refined their driveway concrete cleaning over the past six years. They’re not just about having the right tools—they’ve clearly put in the time to develop a process that balances effectiveness with care.

As a family-run business, they’ve also built a steady reputation for being both detail-focused and easy to work with.

We looked into how they typically handle driveway cleaning, and from what we gathered, their approach is more methodical than most.

They start with a chemical soak to help loosen grime, tyre marks, and algae buildup—something that’s especially helpful for older concrete.

Then, instead of using a basic water blast, they follow up with a 20” rotating surface cleaner to make sure the cleaning comes out even across the slab.

A few homeowners also told us how easy it was to bundle in other services like gutter and house washing, which made scheduling simpler and more efficient.

The only downside? Because they’re a small and in-demand team, it can be tough to book a slot on short notice. It’s worth planning ahead if you want to lock something in.

2. Dragonfly Organics LTD

What impressed us about Dragonfly Organics LTD was how many locals speak highly about them. Invercargill residents often mention their friendliness, professionalism, and how efficient they are when handling exterior cleaning jobs—including driveways.

We reached out to learn more about how they approach heavily stained concrete and found their process to be more considered than most. Instead of offering a quick fix, they asked specific questions.

They wanted to know what caused the stains, whether any treatments had been used before, and how the water runoff behaved in the area.

Their cleaning method also seemed to reflect that attention to detail. From what we heard, they work in sections and tailor their pressure settings to the condition of the surface, helping prevent damage or uneven results.

One homeowner even pointed out that the job felt efficient without being rushed, and they liked being able to coordinate driveway and house washing in one go.

If there’s one downside, it’s that the quoting process can take a couple of days. It’s not a major delay, but something to keep in mind if you’re working on a tighter timeline.

Excellent communication and incredible results

“So impressed with the quality of service from these guys. Excellent communication and the end result was incredible. I used them to do a deep clean at a rental property and couldn’t be happier. It looked like a completely different house. Thanks team!”

3. Nexus Property Services Ltd

Nexus Property Services Ltd is pretty popular among property owners. Many regularly rely on them for exterior upkeep.

Their name kept coming up—not just for how well they handle driveway cleaning, but also for general maintenance.

One of our colleagues had previously hired them for his neglected driveway, and we were able to observe how they approached the job. From surface prep to the final rinse, their process appeared deliberate and methodical.

They worked in sections, applied just the right amount of pressure, and left the concrete with a clean, even finish—no streaks or signs of surface wear. It stood out as a noticeable improvement over the stained concrete we’d seen before.

We also learned that they offer bundle exterior cleaning, painting, and maintenance services—something that can be especially helpful for rental property owners.

The only drawback? Because they offer such a broad range of services, it can take a bit of back-and-forth to finalize what’s included and when. If you’re not clear from the start, scheduling might take longer than expected.

Excellent job

“Adam was great, professional and did an awesome job!”

4. The House Wash Company

One of our team members recently drove past a property mid-clean and was curious enough to stop and ask who was handling the job—it turned out to be The House Wash Company.

That led us to dig a little deeper and ask the property owner a few questions about their experience.

What stood out to us was their post-service check. Someone came back to walk through the finished work with them and make sure nothing was missed. That follow-up gave the whole thing a more accountable, complete feel.

We also liked that they didn’t just go in full blast—they worked in layers. They started with a soft chemical pre-treatment to loosen up grime, then used moderate pressure for the first pass to lift surface dirt.

After that, they followed up with a second pass focused on the tougher spots, which did more than a single high-pressure rinse ever could.

If we had to nitpick, the updates between confirming the booking and the actual cleaning were a bit sparse.

Reliable, responsive and personable team

“Had originally arranged a quote from another house washing company but when I complained to a relative about the lax responses to appointments and providing a quote, was told about The House Wash Company.

Quotes were similar but I chose the latter because of their immediate responses to every contact I made.

I knew they would be reliable and they were.

As well as being punctual the guys who did the work were not only a credit for the brilliant job they did, but for their great personalities.

As for the work itself: I was amazed that the 26 years of grime on the facia was removed with a soft wash and looked as though it had been painted. The fences, black with embedded mould and green with algae are now like new!

I was very impressed with all aspects of this company and will definitely recommended them to friends and family.”

5. Wash Rite Southland

Wash Rite Southland made it to our list because of its reputation for handling rural driveways, especially with Invercargill’s unpredictable weather and older property layouts.

After talking to a few past clients, what stood out to us was how consistent their work is. They don’t just do a quick wash, and the result actually holds up over time.

We learned that they offer a post-cleaning treatment designed to prevent regrowth, said to last up to 18 months, which adds value if it holds up.

We also appreciate that their team pays attention to small things. Instead of letting runoff pool near garden beds or storm drains, they use containment gear to manage it properly—something that not every company takes the time to do.

They even back their work with a money-back guarantee. Though no one we spoke to had actually needed to use the guarantee, it still speaks well to the confidence they have in their service.

That said, their rates are a bit expensive compared to others we’d looked into. You do get a well-rounded service with thoughtful extras, but budget-conscious homeowners might pause at the quote.

Honest, prompt, and reasonably priced

“Excellent from start to finish, thank you! Glyn was easy to contact, came round promptly for a look and was very honest about what I did and did not need done. Arrived when he said he would and did a lovely job of washing my house, paths and fence for a reasonable price. I wouldn’t hesitate to use Wash Rite again or to recommend them to anyone looking to get their house washed.”
