How to Choose a Car-Park Repair Contractor in NZ

Hiring someone to fix a residential driveway and hiring someone to work on a live commercial car park are not the same job. On a commercial lot the public is driving and walking through the site while the work happens, you are the PCBU responsible for their safety under the Health and Safety at Work Act 2015, and your insurer will care how the job was run if anything goes wrong. A cheap contractor who throws hot mix into a hole and leaves is not a saving. They are a transferred risk that lands back on you.

So vet for the commercial context, not the asphalt. Here is the checklist a buyer should run before anyone touches the lot.

The non-negotiables: insurance and H&S

Start with the documents, because the cheapest quote in the pile is worthless if the contractor is uninsured.

• Public liability insurance. Ask for the certificate and check the cover sum and that it is current. If their work causes a vehicle or injury claim, this is what stands between the incident and your balance sheet.

• Health and safety documentation. As a PCBU you have a duty to engage competent people. A commercial contractor should be able to produce a job safety analysis or site-specific safety plan, not a blank look. If they cannot show how they keep your customers safe while they work, that is your answer.

• Evidence they have done live commercial sites. Carparks under trading conditions are a different discipline from an empty driveway.

If a contractor hesitates on any of these, stop there. These are table stakes for a commercial lot.

Can they work live, without closing your site?

A car park that has to shut for two days is lost revenue and annoyed customers. The real test of a commercial contractor is whether they can keep the lot open while they work.

Ask directly:

• Will they run cones and a spotter to manage vehicles and pedestrians around the work?

• Can they work after-hours or around your trading, section by section, so the lot never fully closes?

• How do they protect the path of travel and the accessible parks while a bay is out of service?

We run cones and a spotter on every public-access car park and schedule after-hours or staged work where the site cannot close. That is the default, not an upsell.

Method: saw-cut-and-seal, or throw-and-go?

This is where the quality gap hides, and you can usually spot it in the quote wording before you ever see the work.

A proper repair saw-cuts back to sound asphalt, removes the failed material, and seals the joints. Sealing the joint is the difference between a repair that lasts and a patch that returns. Water gets in at edges; sealed joints keep it out. A throw-and-go job skips the cut and the seal, drops cold mix into the hole, and the patch pops out with the first wet, cold month, leaving you the same hazard and another invoice.

Read the quote for the method words. "Saw-cut", "cut back to sound asphalt", "seal the joints" tell you they do it properly. "Patch", "fill", "make good", with no mention of cutting or sealing, tell you to ask more questions. Knowing the cowboy red flags before you pay is what separates a one-off fix from a recurring problem. The same care applies whether it is a single pothole repair or a full car park repair across the lot.

What a defensible deliverable looks like

For a commercial lot the repair is only half the value. The other half is the record. Ask what you get when the job is done.

A defensible deliverable is a dated before-and-after photo report: the defect, the saw-cut, the sealed finish, with the date on it. That report is two things at once. It is a maintenance log for your asset, and it is a liability record. If a vehicle-damage or trip claim ever arrives for a date after the repair, the report shows the surface was sound. A contractor who cannot produce dated photos is leaving you with no evidence you acted. We deliver that report on every job, alongside a 12-month workmanship warranty on the repair.

Fixed price, or "we'll see on the day"?

A vague quote is a budget risk. "We'll price it on the day" or "depends what we find" puts the cost outside your control and outside your board paper.

The better model is a fixed price from a photo. You send photos of the defects with something for scale, and you get a fixed quote in 24 hours. The number is the number. It is predictable spend you can take to a budget holder without a caveat, and the work is booked within 48 hours of acceptance. If a contractor cannot commit to a price off clear photos for a straightforward defect, ask why.

References from comparable lots

Finally, ask for references from sites like yours: a retail car park, a body corp, a medical centre, a lot that has to stay open. A driveway reference does not tell you whether they can run a spotter through a Saturday trading rush. Ask the referee two things: did the lot stay usable during the work, and did the repair hold through the following winter. Those two answers tell you more than any brochure.

Run the checklist, then test it

Put your shortlist through this list: insured, H&S-ready, live-site capable, saw-cut-and-seal method, dated photo report, fixed price, comparable references. A contractor who clears all seven is a low-risk choice for a commercial lot.

To see how it works in practice, photograph your defects and get a fixed quote. You will have a fixed price in 24 hours and a booking within 48, with the insurance, traffic management and photo record built in.
