Should I ask for an itemized breakdown on my Ottawa driveway quote?

Absolutely yes — always request an itemized breakdown for any Ottawa driveway quote over $2,000. A detailed breakdown protects you from hidden costs, helps you compare quotes fairly, and reveals whether the contractor is cutting corners on critical components like base preparation.

A proper Ottawa driveway quote should itemize excavation and disposal (removal of existing material and topsoil), granular base materials (Granular B sub-base and Granular A base with specified depths), compaction (number of passes with proper equipment), asphalt thickness (binder course and surface course depths), materials specifications (HL3 surface course, HL8 binder if applicable), and labour breakdown by phase. For interlock projects, you need paver specifications (manufacturer, thickness, colour), bedding sand depth, polymeric sand type, edge restraint materials, and pattern complexity. Concrete quotes should specify concrete strength (minimum 30 MPa for Ottawa), reinforcement type (wire mesh or rebar), finishing method, and control joint spacing.

Ottawa's extreme climate makes base preparation absolutely critical — your quote should specify minimum 300mm compacted Granular B sub-base plus 150mm compacted Granular A base to handle our 1.2 to 1.5 metre frost depth. Contractors who lump "base preparation" into one line item without specifying depths and materials are often planning to cut corners. On Ottawa's clay soils (common in Barrhaven, Orleans, Gloucester), the quote should include geotextile fabric between subgrade and granular base to prevent soil migration.

Red flags in vague quotes include "driveway replacement - $8,000" with no material specifications, missing base depths, no mention of compaction equipment, undefined "standard materials," or prices significantly below market ($3-5 per square foot for quality asphalt work). Quality contractors proudly detail their specifications because proper base preparation and materials are their competitive advantage. Compare the base preparation sections carefully — a contractor quoting 200mm total base versus 450mm total base isn't offering the same product, even if both call it "driveway replacement."

When reviewing quotes, ask specific questions: What's the compacted depth of Granular B and Granular A? What compaction equipment will be used? What's the thickness of each asphalt lift? Is the concrete air-entrained for freeze-thaw resistance? Are permits included? What warranty covers base failure versus surface issues? A contractor who can't or won't answer these questions likely doesn't understand Ottawa's climate requirements or is planning to cut corners that will cause expensive failures within 3-5 winters.
