Ours got so grimy last summer, my mother-in-law asked if we were starting a gravel pit. That was my cue. I couldn’t put off cleaning it any longer.

And I’m not alone. Between Hamilton’s unpredictable weather, road salt, and those mystery stains that somehow survive pressure washers, concrete driveways take a beating. Most of us don’t notice how bad it’s gotten until it’s really bad.

So, my colleagues at Top Reviews NZ and I set out to check some of the best driveway concrete cleaning companies in Hamilton. We wanted to find teams who actually know how to get results without destroying our weekend or our hose. 

Here’s who stood out and why they’re worth the call.

1. H2GO Mobile Wash

H2GO Mobile Wash gave us one of the best driveway cleanings we’ve seen around Wellington.

We hired them to get a better sense of their process, and the first thing we noticed was how low the effort was on our end. Their truck came fully stocked, so we didn’t have to prep or supply anything.

The driveway definitely needed help—there were old oil stains, grime, and moss tucked into the cracks. The technician explained everything as they worked, using a hot steam pressure wash with biodegradable detergent.

By the end, it wasn’t just cleaner—it actually felt safer to walk on, especially where moss had made it slippery before.

We also spoke to a local homeowner who hired H2GO before selling their place. They told us the clean driveway made a huge difference in the home’s first impression.

What really sets them apart is that hot water and steam combo—it handled deep stains better than a cold water pressure wash we’d seen elsewhere. They were also careful around the brick edges, dialling the pressure down to avoid damage.

The only hiccup? It can be hard to book them during busy months. Even though they’re technically available 24/7, you might need to be flexible to get the time you want.

Exceptional service with impressive results

“H2GO Mobile Wash recently washed our windows, driveway and our white siding. Our white siding was covered in black debris, and was way overdue for a clean. Daniel and his crew truly did amazing work on our house that we could not stop admiring how clean it looked! Our house looks brand new!

Their service was exceptional with continuous dialogue in making sure everything was done right! I would definitely recommend them to friends and family. Thank you again!”

Spotless, detailed cleaning

“Had the BEST experience with H2Go Mobile wash today! I had purchased a full house wash with window cleaning using reverse osmosis. My home came out completely spotless! My windows are shining and my brick looks brand new! I had so many old stains that I couldn’t get out after I moved in. The concrete is complete perfection! I added on a driveway clean and they made my interlock driveway, side path and backyard interlock look brand new! All of the weeds completely gone! They even cleaned all the debris away. When I arrived home it looked like nothing ever happened except a perfectly clean property. My neighbour had mentioned that there was some debris on their property, but before they could even mention it, H2Go had taken care of that as well! The MOST considerate, accommodating and attentive to detail company I have ever dealt with.  The crew was so polite and so informative. They made me feel so comfortable 🙂 I will definitely be a returning customer! HIGHLY RECOMMEND!!”

2. DryGutts

DryGutts was founded by two cousins—Mitchell and Josh—who took what started as a basic gutter-clearing job and expanded it into a full exterior cleaning service in Hamilton.

What makes them stand out locally is their understanding of the region’s damp climate. They actually tailor their methods depending on the season, which shows they’re not just following a set routine—they’re paying attention to what works best here.

We scheduled an undercover consultation to ask about their driveway cleaning approach. The technician explained how they adapt their methods based on the surface and showed us the rotary cleaner they usually use to avoid streaks on concrete.

What really caught our attention was their “Full House Package,” which one homeowner mentioned as a good value if you need more than just your driveway done. It includes exterior house wash, gutter cleaning, and roof moss treatment.

They would even give you freebies like window wash and insect control. Considering Hamilton’s damp conditions and bug-prone summers, the freebies actually felt like thoughtful add-ons rather than gimmicks.

The only catch? If you’re not going for a full package, it might take longer to get booked in.

Impressive full exterior clean

“Highly recommend their work. I asked for a complete exterior cleaning, including the driveway, roof, gutters, and pergola, which hadn’t been cleaned since we moved in. I’m really impressed with their work, especially on the pergola. I had no idea our pergola was so beautifully transparent! 😂 I also appreciated the additional window cleaning service, which was excellent. Thanks for your hard work, guys!”

Professional, efficient service

“Thank you Josh & Mitchell for an awesome job done on my home. I got the full package which included a free window clean and Insect control. I was so impressed. They arrived exactly on time, they were professional in their approach & worked efficiently & expertly. My home & driveway look like new again & they even dropped the price from what they quoted as the gutters weren’t too bad.. Can’t fault these all round genuine, nice guys & would highly recommend them. Thanks again Josh & Mitchell. I’ll be sure to get you back next time.”

3. Grime Off Now

Grime Off Now brings over 30 years of exterior cleaning experience to Hamilton—and it shows in their driveway work.

They stood out as a reliable choice, especially for homeowners looking for a no-fuss, long-term solution.

What caught our attention was how straightforward their quoting process is—they offer fixed pricing upfront, which helps take the guesswork out.

Their use of ultra-pure filtered water also stood out. One local homeowner mentioned that after their driveway cleaning, the surface dried without any streaks and looked noticeably brighter, especially around the edges.

What sets them apart is their “Grime Ultimate” plan—a scheduled maintenance option that includes exterior cleanings every few months. It’s a practical choice for anyone who wants to stay ahead of grime without the hassle of last-minute bookings.

We also heard good things about their crew’s work ethic. Homeowners mentioned their punctuality and professionalism—something that’s easy to overlook in quick-turnaround services.

That said, their rates might feel a bit steep compared to a one-off wash from a budget provider.

Consistently thorough, professional service

“We’ve had regular exterior house and internal window cleaning with Grime Off for over five years, and they consistently deliver top-quality results. Their thoroughness is second to none — they don’t cut corners and always leave everything looking spotless. The team is always professional, friendly, and great to deal with. Plus, their pricing is very fair, especially given the level of service they provide. It’s rare to find a company that ticks all the boxes, but Grime Off absolutely does. Highly recommended!”

Quick, efficient service

“This company was recommended to me by a friend and i am so happy with the work they done for us. They came out to see the house to do the quote and to get the job done was so quick. We are very happy with the results our house looks great.”

4. A.D.S. Wash and Seal

A.D.S Wash made it to our list because of their all-in-one approach to driveway care. They combine cleaning, sealing, and even minor asphalt patching into one streamlined service.

One thing that really set them apart was their focus on long-term results. They don’t just wash and go—they seal the surface using a high-end product you wouldn’t typically find in a hardware store.

This approach helps protect the concrete or asphalt from future damage, which is especially useful for high-traffic areas or properties exposed to the elements.

One homeowner we spoke to mentioned that the sealed driveway held up noticeably better against oil stains and water damage, even months later.

We also appreciate that there’s no upfront payment pressure. They don’t invoice until the job is done and the client is happy, which builds a lot of trust.

That said, communication during follow-up work could be tighter. A few customers mentioned delays in hearing back when scheduling reapplications or asking questions.

Great attention to detail and responsive customer service

“Contacted ADS Wash and Seal to do my a major job on interlocking brick for driveway, patio, walks and pool surround. On site visit to provide an estimate which was appropriate and competitive with other companies. Choose ADS based on their responsiveness to e mail. The team led by BJ did an excellent job resetting pavers, adjusting drain spots and replacing cracked stones as needed. Power washing, sanding and sealing followed. The whole job took about 2 weeks but was delayed by weather issues.

Extremely pleased with the final result and the attention given to the final product. Excellent customer service and very responsive to ensure customer satisfaction. I will book this company to do work in the future and would highly recommend them.”

• Greg Peachey, Google Review

Meticulous, friendly service

“I highly recommend A.D.S. Washing and Sealing to everyone for many reasons!Their prices are more than fair. Communication prior to the job date was clear and helpful. They showed up when promised. Lorenzo was thorough and meticulous when applying the concrete sealer and he was a pleasure to have around! Funny, friendly and knowledgeable. 🙂 I am going to contact A.D.S to come back and seal my driveway as well as my parents in the near future. Don’t hesitate to call them, they are awesome!”

5. Mr. Clean Exterior Washing

What we love about Mr. Clean Exterior Washing is their balance of quality and efficiency. They get through jobs quickly without skipping over the small details—something that’s not always guaranteed with high-volume providers.

We heard from their past customers that the technician didn’t just quote and go—they walked through the driveway, pointed out trouble spots, and explained how runoff would be handled.

They use eco-friendly, pet-safe cleaning solutions, which makes the process feel a lot less disruptive—no need to move potted plants or keep pets indoors.

Plus, they take extra steps to protect nearby gardens and fixtures by covering exposed plants. They also redirect runoff away from delicate areas and use low-pressure settings near edges. It showed a level of care that isn’t always guaranteed with exterior cleaning.

That said, they do take their time and work methodically. If you’re expecting a quick in-and-out service, it’s worth asking for a timeframe upfront.

High-quality pressure washing

“Mr. Clean Pressure Washing really nailed it! Their House Washing Hamilton crew made our house look brand new. Gutter Cleaning was a great too—my gutters are finally clear! Loved the Soft Wash option as is way gentler on my home.  Their Pressure Washing Services are high quality, and the Water Blasting on my driveway had great results.  Highly recommend Mr. Clean!”

Affordable professional exterior cleaning

“Highly professional, affordable, and such a good job of cleaning and removing the winter buildup from the exterior of our 2 story home that 2 of my neighbours were so impressed that they booked in and had their driveways done. Thank you so much 👍🏼”
