I believe the biggest mistake in commercial flooring procurement isn't picking the wrong color—it's assuming the lowest per-square-foot price is the cheapest option. After managing a $180,000 annual flooring budget for six years and tracking every single invoice, I've learned that the math on 'budget' LVT doesn't work out the way most project managers think.
Let me show you exactly where it falls apart, using a real comparison from Q2 2024 when we evaluated Karndean against a lower-priced alternative for a 3,200 sq ft office renovation.
The Initial Quote Trap
We got three quotes for the project. The lowest bid came in at $3.49/sq ft for a vinyl product I won't name—let's call it "Brand X." Karndean's quote was $4.85/sq ft for their Art Select Corris Slate LM22 in a glue-down installation.
Simple math said Brand X saved us $4,352 upfront. I almost signed. (Should mention: we were under pressure from finance to cut project costs by 12% that quarter.)
Here's what I almost missed: Karndean's quote included the adhesive, transition strips, and a detailed subfloor prep spec. Brand X's quote was just the planks. No adhesive. No transitions. No mention of subfloor requirements.
Where the Hidden Costs Added Up
I built a total cost of ownership (TCO) spreadsheet after getting burned on hidden fees twice before (note to self: do this at the quote stage, not after). Here's what it revealed for our 3,200 sq ft project:
- Adhesive: Brand X recommended a specific pressure-sensitive adhesive—$680 for the job. Karndean's adhesive was included.
- Transition strips: Seven doorways and two expansion zones: $340 for Brand X. Karndean's included their Korlok transitions.
- Subfloor prep: Brand X required a self-leveling compound on a floor that had minor dips (2mm variance over 6 feet—within tolerance for Karndean's Looselay). That was $950 in materials and labor we didn't budget for.
Total hidden costs: $1,970 on what looked like a $4,352 saving. I still kick myself for nearly signing without doing the TCO analysis. If I'd trusted the per-square-foot price, we'd have blown our budget before the first plank was installed.
The Redo That Cost $1,200
Even after catching the quote issues, I almost went with Brand X—until I talked to two other facility managers in my network. One of them had installed Brand X in a 1,800 sq ft office and had to redo 400 sq ft within 8 months. The seams had lifted near the window line (south-facing, lots of direct sun—a detail their sales rep hadn't flagged).
The redo cost him $1,200 in materials and lost productivity from the office closure. Looking back, I should have asked more questions about Brand X's heat stability specs. Karndean's Korlok click system has a built-in expansion allowance that handles temperature swings better in commercial settings. I want to say that detail saved us from a similar problem, but don't quote me on the exact temperature tolerance—I'd need to dig up the tech sheet.
(Funny how the "cheaper" option always seems to have more footnotes. Surprise, surprise.)
What I Actually Do Now (And You Should Too)
After that close call, our procurement policy now requires:
- Three quotes minimum, but every single one must list what's included vs. excluded. If adhesive, transitions, and subfloor prep aren't itemized, I send it back.
- Warranty language scanned for 'commercial' vs. 'residential'—some budget brands limit commercial coverage to 5 years vs. 15+ for Karndean's commercial lines. That difference alone justified the premium if we planned to stay in the space past year five.
- Installation history check. We ask for three commercial references from the installer, specifically asking about failures. Not just happy customers—failed installations teach you more.
An informed customer asks better questions and makes faster decisions. I'd rather spend 10 minutes explaining the TCO math to a stakeholder than deal with a $1,200 redo six months later.
Look, some projects genuinely don't need premium LVT. A short-term rental space with a 24-month lease? Maybe the cheap option fits. But for any flooring project you expect to last more than three years—especially in a commercial setting with foot traffic, sunlight, and cleaning schedules—calculate the total cost, not just the per-foot price. That's the difference between a cost controller and someone who just signs the check.
If I could redo that decision from Q2 2024, I'd still pick Karndean. But given what I knew then—nothing about Brand X's adhesive requirements or heat stability—my hesitation was reasonable. Now I have the data to back it up.
