What should I look for in a patio contractor's quote in Ottawa?

A thorough patio contractor's quote in Ottawa should give you a clear picture of exactly what you're paying for, how the work will be executed, and what protections you have if something goes wrong. Vague or incomplete quotes are the single biggest source of disputes in outdoor construction, so knowing what to look for saves you real headaches down the line.

Start with the base preparation specification. This is the most critical section for any Ottawa patio project because our Champlain Sea clay soil is notoriously unstable. The quote should state the excavation depth, the type and depth of granular base material, and the compaction method. For a standard paver patio on Ottawa clay, you want to see 10-12 inches of compacted Granular A base and a 1-inch layer of bedding sand or screenings. If a quote simply says "prepare base" without specifying depth and materials, that's a red flag. Contractors who cut corners on base preparation can save $2,000-$3,000 on a typical project, but you'll pay for it when the patio heaves after the first winter.

Material specifications should be detailed and specific. The quote should name the exact paver brand, product line, colour, and size. "Interlocking pavers" is not a specification. "Permacon Mondrian 80mm in Champlain Grey" is a specification. This matters because material costs vary significantly between product lines, and you need to be able to verify that what shows up on the delivery truck matches what you agreed to pay for.

Look for a clear scope of work section that describes every phase: demolition or removal of existing surfaces, excavation, base installation, edge restraint type and placement, paver installation pattern, polymeric sand application, and final compaction. Each of these steps has associated costs, and bundling them into a single line item makes it impossible to compare quotes meaningfully.

Drainage planning should be addressed explicitly. Ottawa's clay soil drains poorly, so your patio needs proper slope away from the house foundation, typically a minimum of 2% grade. If the site has specific drainage challenges, the quote should describe how they'll be handled, whether that's a French drain, catch basin, or grading adjustments to surrounding landscape.

Permits and compliance matter in Ottawa. Patios within certain setback distances from property lines or above certain heights may require permits. The quote should state whether permit fees are included and who handles the application. Any electrical work for lighting needs ESA certification, and gas lines for fire features require licensed gas fitter involvement with proper permits.

Finally, check for warranty terms, payment schedule, and timeline. A reasonable payment structure is 10-15% deposit, a progress payment at base completion, and final payment upon completion and your walkthrough approval. The warranty should cover both materials and workmanship for a minimum of two years, with specifics on what constitutes a warranty claim. Getting three detailed quotes from Ottawa patio contractors and comparing them section by section gives you genuine insight into who understands the work and who's guessing at a price.
