Most renovation quotes aren’t wrong on purpose.
They’re just incomplete.
And that’s where problems start.
We’ve seen it many times—projects that look good on paper early on, but end up going over budget, taking longer than expected, or creating frustration along the way.
The issue usually isn’t one big mistake. It’s a series of small things that weren’t fully accounted for upfront.
1. The Scope Isn’t Fully Defined
This is the biggest factor.
If the full scope of work hasn’t been clearly worked through during design, it’s almost impossible to produce an accurate number.
Things get missed. Assumptions get made. Decisions get pushed into construction.
That’s when costs start to move.
At PHH, we spend more time upfront working through details so the pricing reflects the actual project—not a partial version of it.
You don’t save money by missing scope—you just delay paying for it.
If you want to see how this ties into overall cost, our renovation cost guide breaks it down further.

2. The Number Looks Good—But Something’s Missing
If a quote comes in significantly lower than others, there’s usually a reason.
In most cases, our overall pricing is in line with other builders. The difference is that we work to identify the full scope and real costs earlier in the process.
When numbers vary significantly, it’s often because different assumptions are being made—not because the actual project costs less.
Those costs don’t disappear. They show up later.
We’d rather have that conversation before construction starts than after money has already been spent.
3. Allowances Instead of Real Pricing
Allowances are one of the most common ways quotes look clean early on.
They’re often used for:
- Cabinets
- Fixtures
- Flooring
The challenge is that they’re just placeholders.
If the allowance doesn’t match what the client ultimately selects, the cost increases later.
Our goal is to minimize allowances as much as possible by pricing real items during design. It creates a much clearer picture of where the project is actually landing.
4. Labour, Trades, and Material Quality Vary More Than People Think
Not all pricing is created equal.
There’s a wide range in:
- Subtrade quality and reliability
- Labour experience
- Material durability
Some finishes and materials can look good initially, but don’t hold up over time. We’ve seen homes just a few years old that already show significant wear due to lower-quality materials or workmanship.
The same applies to trades. Lower-cost crews can impact schedule, quality, and the overall experience.
You can often reduce cost in these areas—but it usually comes with trade-offs.

5. Low Bids Often Lead to Higher Final Costs
This is something we see regularly.
A project starts with a lower number, but as the job progresses:
- Scope gets added
- Allowances get exceeded
- Changes get introduced
By the end, the project costs more than higher initial quotes—and often with more stress along the way.
We’ve had people come back after the fact saying they chose the lower bid and ended up with both a higher final cost and a worse experience.
It’s not something you can fix after the fact, which is why getting it right upfront matters.
6. Lack of Transparency
One of the biggest differences between quotes is how much visibility you have into them.
Markup is fairly consistent across the industry. Most builders are working within a similar range—it’s not usually where major differences in price come from.
The biggest difference between quotes is how complete and accurate the scope is—and how clearly it’s presented.
If you don’t know what’s included—or how the number was built—it’s difficult to compare or trust it.
We take an open-book approach.
If clients want to see how numbers are built—materials, labour, trades—we’re happy to walk through it. There are no hidden pieces.
Our Approach
We work on a time and materials basis, which allows us to stay aligned with the client throughout the project.
Rather than relying on assumptions or allowances, we’re working with real costs as decisions are made—so there’s clarity the whole way through.
That means:
- Better visibility
- More accurate budgeting
- Flexibility to make informed decisions
The focus isn’t on finding savings to increase margin—it’s on building the best project possible within the client’s budget.

Final Thoughts
Most issues with renovation quotes don’t come down to one big mistake.
They come from incomplete information, unclear scope, or assumptions made too early.
The more clarity you have going into a project, the better the outcome tends to be.
