Kaitiakitanga - We show respect for our taiao and minimise environmental impact.

As a Qualified Stone and Tile Technician, Stone Lab have the experience and knowledge, and we provide solutions and restorations for your Natural and Engineered stone surfaces. 

We have a passion for Natural Stone and enjoy working with each piece.  Natural stone is alive, and when treated with care, it will reveal its personality and beauty.  Our skill set allows us to restore the natural stone to its former glory.  We are dedicated to caring for your stone investment.

We provide anti-graffiti protection for stone porous substrates, without changing the natural look of the substrate and retains water vapor permeability (breathability). We have the full range of protection for Natural Stone and Terrazzo flooring, including penetrating and topical treatments to give longevity and provide easy maintenance.

We provide the full range of cleaning and sealing of exterior natural stone cladding.
With the use of our water based Hydro-repellant treatments, we can treat concrete tilt slabs two weeks after pour. The most common sedimentary cladding such as Sandstone, Tuff and Limestone require correct treatment to stop salt damage, mould growth and moisture damage. Basalt and Granite requires a very robust treatment formula to withstand heat and sun exposure.  They also require treatments that do not alter its natural look.

Frequently Asked Questions

Can you fix the chip to my benchtop?

Yes, we'll assess your benchtop to ascertain which method will be used to give you the optimal result. We pride ourselves on close colour matches and a great majority of the time, you can't see where the repair has occurred.

Can you fix my chipped vanity, even if I don't have the chipped piece?

Yes, no problem. And it will be our goal to repair the chip so it is unnoticeable.

I have scratches on my benchtop, can you remove these?

Yes, we use a variety of polishing machines to bring your benchtop back to a polished finish, or honed; the choice is yours.

I have stone tiles that look dull. Can you make them shine again?

Yes, definitely! We can have your floors and walls looking fresh and like new in no time!

My shower base has lost its shine and looks cloudy, can this be fixed?

Yes, our 'Natural Stone Restoration' process and 'Deep Cycle Cleaning' process will restore your Marble, Granite, Limestone, and Travertine bathroom tiles to their former lustre.

How often should I re-seal my stone?

We recommend for both Natural stone tiles and benchtops to re-seal every two years. We offer a professional sealer application, using the highest quality sealer that allows the stone to breathe.
