After 20 years running renovation jobs in Ottawa, I can tell you the spread between the lowest kitchen quote and the highest one almost never comes down to skill. It comes down to what's printed on page two of the contract, and what's deliberately left off.
Most homeowners read three quotes, pick the middle one, and assume they've split the difference fairly. They haven't. They've usually picked the contractor who's best at writing comfortable-looking quotes, not the one who's best at building.
Here are 10 things the trade knows about its own pricing that homeowners almost never get told. None of this is illegal. Most of it is standard practice. All of it costs you money if you don't see it coming.
1. Your "deposit" is funding someone else's job
If a contractor asks for 40% or 50% up front before any work has started, that money isn't sitting in escrow waiting for your cabinets to ship. It's paying down their last project's lumber bill, or their truck loan, or their crew's payroll on the job they're finishing this Friday.
This is how small operators stay liquid. It's also why those same operators sometimes ghost mid-project: their next deposit didn't land in time. A healthy contractor takes 10% to 15% on signing, then bills against milestones tied to actual installed work. We tie ours to inspections, not invoices.
2. The "labour and materials" line hides a 20% to 35% sub markup
When your quote shows a single price for electrical, that's not what the electrician charged. The contractor added 25% to 35% on top of the sub's number because they're the one carrying the schedule risk, the warranty, and the chasing-them-back-for-deficiencies headache.
That markup is legitimate. But it's never disclosed, and the homeowner usually has no idea the underlying number even exists. Ask to see the sub's quote. Most contractors will refuse. The ones who show you are usually the ones charging the smaller markup.
3. Vague scopes are intentional
"Renovate kitchen, supply and install cabinets, counters, backsplash, lighting" is not a scope. It's a promise to argue later. A real scope names the cabinet brand, door style, drawer count, counter slab, edge profile, faucet model, can-light count, switch locations, and which existing fixtures get reused.
If the scope is vague, every clarifying conversation becomes a billable change. By month two, you've added a stack of "we forgot to include" charges. That's not an accident. Real estimating takes 8 to 14 hours of paid pre-construction work. Free quotes can't afford to be specific.
4. The timeline is set by lead times, not skill
An average Ottawa kitchen renovation runs 6 to 10 weeks of on-site work. But the schedule is set 4 to 12 weeks before anyone swings a hammer, by your cabinet lead time, your counter template-and-install gap, and whether the appliances ship from a Canadian DC or a US one.
A "fast" contractor isn't faster on site. They're better at sequencing the order chain so they're not waiting for one back-ordered sink to delay the entire install. Ask any contractor how they handle a 14-day cabinet delay. The good ones have a written answer. The rest say "we'll figure it out."
The 12-week math nobody shows you
For an Ottawa kitchen we order: cabinets at week 0 (8-week lead), counters at week 6 (template after install), tile at week 0 (warehouse stock), appliances at week 4 (often 2-week confirmation). Miss any one of those windows and the install date slips by two weeks, not two days. The contractor who quotes you "8 weeks" without naming the cabinet shop is guessing.
5. Allowances are the silent budget killer
A tile allowance sounds generous until you realize it has to cover supply, delivery, waste factor, and sometimes labour, for a 90 sq ft floor and 30 sq ft of backsplash. Once you add mid-tier porcelain, plus a 15% waste factor, plus underlayment, a thin allowance gets used up fast.
Allowances aren't dishonest, but they're often chosen low so the headline number looks competitive. Always ask: "What does this allowance buy at the showroom you'd recommend?" If they can't answer, it's a placeholder, not a budget.
6. The $117 permit isn't the permit cost
Ottawa's minimum building-permit fee is $117. That number gets quoted to homeowners as "the permit cost" and it's almost always wrong. The actual permit fee scales with the work: a kitchen with a wall removal, a basement legalization, and a large addition each sit at different fee tiers, and the bigger the project, the higher the fee.
Then there are the soft costs: the BCIN designer, the structural engineer's letter, the survey if you don't have one. These belong in the budget conversation on day one, not on invoice three. Here's how Ottawa permits actually work.
7. "We don't need a permit for that"
Yes, you do. In Ontario, any structural change, any new plumbing fixture rough-in, any new electrical circuit, any basement bedroom, and any addition over 10 sq m needs a permit. Period.
Contractors say "we don't need one" because the permit slows them down 3 to 6 weeks and forces inspections they'd rather skip. The risk lands on you: when you sell, the lawyer asks for closed permits. Unpermitted work shows up on title searches and kills deals or carves a meaningful chunk off your sale price. That's not theory; that's three Ottawa real-estate lawyers we've talked to this year.
8. Change orders are the profit margin
On a tight competitive bid, a contractor's gross margin might be 12% to 18%. The way that becomes a healthy 25% to 30% is change orders. Every "while we're at it" item gets priced at retail plus markup, with no competitive pressure because the wall is already open.
Some of those change orders are real (you genuinely added scope). Some are manufactured (something that should have been in the original scope is now an "extra"). The rule we tell our clients: a fixed-price contract should only generate change orders if YOU change scope. If they're changing scope, that's a quote error, not a change.
9. The lowest quote almost always wins, then loses
Ottawa homeowners pick the lowest of three quotes about 70% of the time. Of those, our internal experience and what other Ottawa contractors share at supply houses suggests roughly half end up paying more than the second-lowest quote would have charged, after change orders, allowances, and overruns.
The lowest quote isn't necessarily the worst contractor. It's just the one who left the most off the page. If two of three quotes are within 10% and one is 25% lower, that 25% gap isn't efficiency. It's something missing from the scope.
The cheapest quote is rarely the cheapest job. It's just the latest one to start the math.
10. The crew on day one is not the crew on day forty
Many Ottawa renovation companies run lean on payroll and rely on day-rate subs. The framers who showed up Tuesday might be a different two-man crew than the ones who finish drywall in week six. That's not always bad, but quality varies, and accountability splinters.
Ask: "Are these your employees, or are they subbed out?" An in-house crew costs the contractor more (WSIB premiums, training, downtime, vacation). It also means one supervisor knows your job from demo to punch list. We carry our framers, finish carpenters, and cabinet shop in-house. Most of our competitors don't, and you can hear it in the answer.
What this means for your next quote
You don't need to become a contractor to read a quote well. You need three specific things in writing before you sign anything:
- A defined scope that names cabinet brands, fixture models, finish products, and quantity counts. Not "kitchen renovation."
- A payment schedule tied to inspections or installed milestones, not calendar dates. Calendar dates encourage padding the deposit; inspections encourage finishing the work.
- A written change-order policy stating that new scope must be signed before work happens, with a per-line breakdown of materials, labour, and schedule impact.
If a contractor pushes back on any of those three, that's the conversation telling you what you need to know. The good ones welcome it. They've been waiting for someone to ask.
If you want a quote written this way for your project, our Ottawa renovation team walks every client through scope, allowances, and change-order rules before signing. No deposits taken until you've seen the line items.
