The carpet's tired. The complaints have started. The building owner has signed off the budget and you've got a multi-floor carpet replacement on your plate for the next quarter. Now you need a contractor.

On paper, this looks straightforward. Lift the old tiles, install the new ones, manage the schedule, hand it back.

In reality it's one of the more disruptive things you can do to a tenanted commercial building, and the contractor you pick will determine whether the project ends with a quiet handover or a backlog of tenant complaints and warranty disputes.

The frustrating part is that most flooring contractors look fine on a capability statement. The differences only show up under load, on a real job, when level six runs late, a worker calls in sick on a Wednesday, or a tenant lodges a complaint about adhesive smell at 9am on a Monday. By then it's too late to swap horses.

So before you sign, ask five questions. The answers will tell you everything.

"Show me how you plan and stage the job."

If the answer is a spreadsheet and a WhatsApp group, keep looking.A multi-floor carpet replacement needs real planning tools.

Floor-by-floor sequencing that respects tenant occupancy, crew allocation by skill, materials staging in a building that doesn't have a construction site to dump pallets in, daily progress tracking, and live reporting back to you so you're not chasing for updates. None of that lives well in a spreadsheet.

Ask to see the system, not hear about it. A contractor who can pull up their planning tool on the spot and show you how they're tracking another live project is operating on a different level to one who tells you they "use a project plan in Excel."

At Premrest we built our own. The whole business runs on a custom operations platform that handles project planning, crew scheduling, materials, daily reporting, photos, variations and sign-offs in one place. We did that because the off-the-shelf options weren't good enough for what we were trying to deliver, and because the only way to give clients real visibility is to control the tooling end-to-end.

"Who's actually on site, and how many of them?"

A multi-floor carpet replacement is, fundamentally, a workforce problem. The square metreage is fixed. The deadline is usually fixed. The only variable is crew depth.

Ask: how many installers will be on site each night? How many supervisors? What happens if one of them is sick on day four? Are they direct employees, long-term subcontractors, or labour-hire churn? Have they worked together before?

A small contractor running two installers and a ute can do a beautiful job on a single floor. They cannot do five floors in three weeks of after-hours work without either falling behind or quietly thinning the crew at the back end of the project, which is where quality slips and you stop noticing because everyone's worn out, including you.

You're not buying carpet tiles. You're buying delivery capacity. Make sure there's enough of it.

"How do you handle a live building?"

This is the question that matters most on a standalone carpet replacement, because unlike a fit-out, there's no construction program to hide behind. The building is fully tenanted, fully operating, and you're the one wearing every complaint.

Ask how they manage after-hours access and key handovers. Ask about dust suppression, adhesive odour control, and how they protect adjacent areas during demolition and install.

Ask how they coordinate lift bookings with building management, how they sequence work to avoid disrupting tenant business hours, and what their plan is for a tenant complaint mid-project.

If the answer is a shrug, your help desk is about to light up. If the answer is a clear, rehearsed account of how they've done this before on similar buildings, you've found someone who's actually done the work.

The contractors who do this well treat a live-building job more like facility management than construction. That's the right mindset, and it's worth testing for.

"What happens after the warranty period ends?"

This one separates the field cleanly.

Most flooring contractors are only flooring contractors. Their commercial model is built around getting through the defects liability period without a call-back and moving on to the next job. Once the warranty is over, they're off the hook and out the door. That's not a criticism, it's just the structure of the business. Their incentives are time-bounded.

We're different. We also run a national commercial floor care business, which means we have a separate commercial reason to want every floor we install to perform well long after handover.

We're motivated to do the prep properly, sequence the install correctly, and finish the floor in a way that holds up under years of cleaning and traffic, because we'd love the chance to be the team caring for it afterwards.

Same company, two specialties, aligned incentives. It's a structural difference, not a marketing one, and it shows up in the way we approach the build.

"What does your reporting look like?"

You shouldn't have to chase your contractor for a status update. If you do, that tells you everything about how the rest of the job will run.

Good reporting on a large install looks like this: daily progress against plan, photographs of completed work, materials consumption tracked against estimate, variations logged and approved in writing, defects identified and triaged, completion sign-offs collected as you go. All of it visible to you, all timestamped, all in one place.

If reporting is an afterthought, accountability will be too. And on a multi-floor capital project, accountability gone missing in week one becomes a documentation nightmare by week six when you're trying to close out variations and the contractor's WhatsApp history isn't quite the audit trail you'd hoped for.

The point isn't us. The point is the questions.

You can take these five questions to any contractor you're considering, us included. They're designed to surface the difference between contractors who've built real delivery capacity and contractors who haven't.

For an FM or building owner planning a multi-floor carpet replacement, asking them upfront will save you from the most common ways these projects come unstuck. The good contractors will welcome the questions. The ones who don't have good answers will tell on themselves quickly.

P.S. The honest version of this article is shorter: ask the contractor to show you their system, count the crew, and ask what happens after the warranty ends. If they answer well, the other two questions take care of themselves.
