Costs & quotes
Know what your project should cost before you sign anything.
Get realistic planning ranges, understand what moves the price, and know what to look for when contractor quotes start coming in.
What moves the price
Ten things decide the number on your estimate.
Two homes on the same street can get very different prices for the same project. These are the variables that explain most of the gap.
01
Project size
Square footage, linear feet or unit count is usually the single biggest multiplier.
02
Materials
Grade, brand, finish and warranty length can move the same scope by thousands.
03
Labor complexity
Height, pitch, tight access and detailed finish work all add hours.
04
Property condition
Rot, old wiring, failed waterproofing or settling changes the real scope.
05
Location
Local labor rates, material freight and demand shift the same job by metro.
06
Accessibility
Second storeys, narrow lots and limited parking add staging and time.
07
Removal and disposal
Tear-off, dumpsters and haul-away are real line items — or a real omission.
08
Permits and inspections
Fees, drawings and inspection time belong in the estimate, not as a surprise.
09
Upgrades
Fixtures, glass packages and efficiency options are where budgets quietly climb.
10
Hidden repairs
Anything found once the surface is opened is why a contingency exists.
Local cost intelligence
What projects actually cost near you.
Project costs vary because scope, materials, home conditions and location vary. Treat ranges as guidance, not a guaranteed price.

Quote comparison
Why two quotes for the same roof can look nothing alike.
A simplified example. Both contractors were asked for a roof replacement — only one of them priced the whole job.
Quote A
$18,500
Includes
- Full tear-off
- Premium materials
- New flashing
- Disposal
- Written warranty
- Permit
Quote B
$14,200
May exclude
- Disposal
- Flashing replacement
- Permit
- Decking repairs
The cheapest number is not always the cheapest project.
Before you accept
Ten things to check in the quote itself.
Work down this list with each estimate in front of you. Anything you cannot find is a question, not a problem — ask it before you sign.
Scope of work
Written in enough detail that two contractors would build the same thing.
Materials
Brand, model, grade and quantity — not just “quality materials”.
Labor
Who does the work, crew size and whether trades are subcontracted.
Warranty
Workmanship and manufacturer cover, both with a stated length.
Permits
Who pulls them, who pays, and what inspections are expected.
Disposal
Tear-off, dumpsters, haul-away and site clean-up.
Change orders
How extra work is priced and approved before it happens.
Payment schedule
Deposit, milestones and a final payment tied to completion.
Exclusions
What is explicitly not included — often the most useful section.
Timeline
Start window, working days and what happens if it slips.
Cost red flags
Pricing signals worth a second look.
None of these mean a contractor is dishonest. They mean the estimate needs explaining before money changes hands.
The price sits dramatically below every other quote
A large share of the total is requested upfront
Obvious work — disposal, flashing, permits — is missing from the scope
Materials are described in adjectives instead of model numbers
There is no written warranty, only a verbal promise
Nobody will explain how extra work gets priced
Not sure whether the project needs a repair or a full replacement?
Sometimes the biggest cost decision happens before you request a quote.
Cost & quote questions
Questions homeowners ask about pricing.
Why do contractor quotes vary so much?
Most of the gap is scope, not skill. One quote may include tear-off, disposal, flashing, permits and a decking allowance while another assumes none of it. Compare the line items before comparing the totals.
What affects the cost of a home improvement project?
Project size, material grade, labor complexity, the condition of your home, access, disposal, permits, chosen upgrades and any hidden repairs found once work starts. Location then shifts labor and material pricing on top of all of that.
How many contractor quotes should I compare?
Three is the common benchmark, because it shows you the shape of the market rather than a single opinion. What matters more than the count is that each quote covers the same written scope.
What should be included in a contractor estimate?
A detailed scope of work, materials with model numbers, labor, permits, disposal, warranty terms, a payment schedule, change-order rules, clear exclusions and a timeline.
Does the cheapest quote usually save money?
Not reliably. A lower number often reflects less work — no tear-off, no permit, no disposal, no allowance for repairs — so the difference tends to reappear as change orders later.
