What is the typical markup from contractors on patio materials in Ottawa?

Understanding contractor markup on patio materials helps Ottawa homeowners evaluate quotes more realistically and recognize that markup is not the same as profit gouging — it covers legitimate business costs that keep a professional operation running. The typical range in Ottawa is 15 to 35 percent above the contractor's wholesale cost on materials, with most established patio contractors landing between 20 and 30 percent.

To put real numbers on this, consider interlocking pavers. A homeowner buying from an Ottawa landscape supply yard might pay $4.50 to $7.00 per square foot for a mid-range Permacon or Techo-Bloc paver. A contractor with a trade account at the same supplier typically pays $3.00 to $5.50 per square foot. The contractor then marks up that cost by 20 to 30 percent on your quote, so you see $3.60 to $7.15 per square foot. In many cases, the contractor's marked-up price is close to or even below the retail price you would pay walking in off the street, because supplier trade discounts can be substantial — ranging from 15 to 40 percent below retail depending on the contractor's purchase volume and relationship with the supplier.

The markup percentage tends to vary by material type. Commodity materials like granular base, concrete, and framing lumber typically carry lower markups of 15 to 20 percent because pricing is transparent and homeowners can easily comparison shop. Specialty items like natural stone, composite decking, and outdoor kitchen components tend to carry higher markups of 25 to 35 percent because they involve more supplier coordination, potential waste from cutting, and the contractor's expertise in material selection and quality assessment. Natural stone in particular can vary enormously in quality within the same price tier, and an experienced contractor's material selection skill has real value that the markup partially reflects.

What the markup actually covers is worth understanding. Beyond the material cost itself, contractors use markup revenue to pay for material delivery to your site, storage and handling, waste and breakage (typically 5 to 10 percent of materials on a patio project), warranty callbacks related to material defects, vehicle and equipment costs for pickup, insurance on materials in their possession, and the administrative time spent sourcing, ordering, and coordinating deliveries with your project schedule. A patio project in Ottawa also requires careful material timing — ordering too early means storing materials through unpredictable spring weather, ordering too late means potential delays during the compressed May through October building season.

Some Ottawa patio contractors use a different pricing model altogether, quoting labour and materials as a single per-square-foot or lump-sum price rather than itemizing materials separately. This is actually the more common approach for established contractors, and it makes markup less visible but no less present. A typical all-in installed price for a mid-range interlocking paver patio in Ottawa of $18 to $28 per square foot includes both the material cost and the contractor's margin built into the total.

A few practical considerations for Ottawa homeowners. Asking contractors to use materials you purchase yourself (owner-supplied materials) to avoid markup usually backfires — most contractors either refuse, charge higher labour rates to compensate, or will not warranty work done with materials they did not source. The warranty issue is significant because if a paver cracks or a stone veneer debonds, the contractor needs to know the material came from a source they stand behind. The more productive approach is getting two or three detailed quotes from local patio contractors and comparing total project costs rather than trying to dissect individual line items. Contractors who are confident in their pricing are usually willing to walk you through their quote in detail and explain what you are paying for.
