How much does it cost to cut a hole in a concrete wall? Decoding the Concrete Conundrum

Posted on by Olivia Armstrong

If you’re contemplating a new window or simply need to run utilities through a stubborn concrete wall, you’re undoubtedly pondering the costs of concrete wall cutting. In Auckland, prices can range anywhere from $15 to $30 per linear metre, depending on factors like the thickness of the concrete wall and project complexity.

Concrete Coring Explained

When installing utilities or creating openings, you might come across concrete coring. This process involves extracting cylindrical sections from a concrete structure, typically through the use of a core drill. If you’re considering concrete coring services, be prepared to shell out around $100 per hole for diameters less than 50mm. Bigger or more intricate tasks might find you parting with upwards of $500.

Breaking Down Concrete Drilling

Concrete drilling, on the other hand, refers to the action of boring holes into concrete structures, usually using a diamond drill bit. The pricing metric here is typically per hole, with simple, small-scale projects costing around $20 each, while larger or more complicated tasks could reach up to $200 or more.

Suburb-specific Considerations in Auckland Impacting Cost

In the character-filled suburbs of Parnell and Ponsonby, brick structures are a common sight. Here, you might require the services of a brick cutter, with brick wall cutting costs falling between $15 and $25 per linear metre, again depending on the wall’s thickness. In contrast, the hilly terrain of Titirangi might require rock cutting, the cost of which can vary widely, so it’s always wise to obtain a custom quote from Auckland concrete cutters.

Navigating Auckland’s Health and Safety Requirements

Safety is paramount in any construction-related work, including concrete drilling and cutting. Be prepared to use safety glasses, dust masks, and hearing protection as these are requirements under Auckland’s Health and Safety regulations.
