“Your quote is higher than the other company — can you lower it?” It’s one of the most common conversations in the cabinet and joinery business. When a homeowner receives two quotes that differ significantly, the natural instinct is to choose the cheaper one, or to use it as leverage to negotiate the higher one down. But in most cases, the price difference between cabinet quotes reflects genuine differences in material specifications and structural decisions — differences that are essentially invisible at the point of installation, and only become apparent months or years later.

The Hidden Variable: Single-Panel vs Double-Panel Side Boards

The side board (or side panel) of a cabinet carcass is one of its most structurally critical components. It carries the weight of the contents, provides the surface to which other panels are joined, and determines how well the cabinet maintains its shape over time.

In lower-cost cabinet construction, side boards typically use a single panel of board material. This is cheaper to produce and looks identical to higher-specification work at the point of installation. The structural consequences only emerge gradually:

Progressive bowing under load: A single panel has limited stiffness in its own plane. Under the sustained weight of stored items — particularly heavy ones like pots, books, or appliances — the panel can develop a barely perceptible bow over time. Once the panel bows, the geometry of the entire carcass is affected.
Connection point loosening: As panels deform slightly, the joints between them — held by screws or dowels — lose their precise alignment. Hinges and drawer runners that depend on precise panel geometry begin to function less smoothly.
Reduced load tolerance: Heavy items stored in a single-panel cabinet are more likely to cause visible sagging or settling of the shelves above.

Double-panel side boards — where two panels are bonded together to form the structural side — address these problems directly. The bonded double panel is substantially stiffer, more dimensionally stable, and holds its shape more reliably under sustained load. Based on experience across hundreds of installations, the improvement in long-term durability and rigidity with double-panel construction is measurable and significant.

A Functional Bonus: Concealed Wiring and Flush-Mounted Sockets

Double-panel construction provides a structural benefit, but it also enables a design feature that single-panel work cannot: the cavity between the two bonded panels can be used to route electrical wiring and accommodate flush-mounted power sockets.

In contemporary kitchen, study, and living room cabinet design, built-in power access is increasingly expected. Appliances need power points; charging devices need accessible sockets; under-counter lighting needs wiring. The cavity in a double-panel side board provides a clean, invisible route for all of this — the finished result has no exposed conduit, no surface-mounted trunking, and no aesthetic compromise. The socket appears to emerge neatly from the cabinet surface.

Single-panel construction simply doesn’t provide this option. Achieving the same result with a single panel requires surface-mounted conduit or external cable management — both of which introduce visible elements that undermine the clean finish.

The Difference Is Invisible at Handover — But Cumulative Over Time

This is precisely what makes comparing cabinet quotes difficult for homeowners: the structural differences between high and low specification work are almost entirely invisible at the point of installation. Both cabinets may have the same door style, the same colour, the same surface finish. The inspector cannot tell from the outside whether the side board is single or double panel.

The difference reveals itself gradually. After a year or two, the lower-specification cabinet may show slight door misalignment — the reveal between panels becomes slightly uneven, or a door begins to sit slightly crooked. Drawer operation becomes less smooth. The cabinet body, when viewed carefully, shows a barely perceptible departure from perfectly straight lines. These are gradual changes that many homeowners attribute to the cabinet simply “getting old” — but the root cause is insufficient structural rigidity from the beginning.

A well-specified cabinet with double-panel side boards, quality board material, and proper hardware maintains its geometry reliably for a decade or more. The maintenance costs over that period are negligible.

What to Ask When Comparing Cabinet Quotes

Rather than using the cheaper quote to pressure the more expensive contractor down, the more useful approach is to get clarity on what each quote actually includes. Specific questions worth asking:

Are the side boards single-panel or double-panel construction?
What brand and grade of board material is used for the carcass? What density specification?
Are door panels specified at a different (thicker) specification from the carcass panels?
What brand of hardware is specified — hinges, drawer runners, handles — and is this included in the quoted price?
Can I see a completed example of your work, either at a reference site or through detailed, unedited photographs?

If both quotations include genuinely equivalent specifications across all of these dimensions and one is still significantly cheaper, that’s a reasonable point of negotiation. If the specifications differ — as they usually do — the price difference is not arbitrary, it reflects what you’re actually getting.

Higher Price Is Not the Same as More Expensive

“Higher price, but better value” sounds like marketing language, but it reflects a straightforward financial reality in the renovation industry: quality materials and construction methods have a genuine cost. A quote that is significantly below market rate is, by definition, achieving that price by reducing something — board grade, panel construction, hardware quality, or labour time. There is no other way to arrive at a significantly lower number.

A well-built cabinet set may last 15 years with minimal maintenance. A lower-specification equivalent may require attention or partial replacement within 5 years — and the aggregate cost of those interventions, combined with the inconvenience, can exceed the original price difference several times over.

Viewed over a realistic ownership period, slightly higher initial investment in quality construction is almost always the more economical choice.

Conclusion: Compare Specifications, Not Just Numbers

Wide variation in cabinet quotes is not a sign of an industry that overcharges — it’s a reflection of genuine differences in what’s being offered. Before making a decision based on the bottom-line number, invest a little time in understanding what each quote includes. Ask about panel construction, board specification, hardware brands, and workmanship standards.

When you understand what you’re comparing, you’re in a much better position to choose the right contractor — not the cheapest one, and not necessarily the most expensive, but the one whose specification genuinely matches what you’re willing to pay for and what your home deserves.
