How to request a construction estimate
This step-by-step guide shows owners and operators in the GTA and Ontario exactly what to gather, how to submit a clear request, and how to compare contractor estimates line by line. You will get a copyable one-page template to use when you request a construction estimate, a checklist for attachments, criteria to compare labour, materials, allowances, exclusions, contingencies, and the warning signs to watch for before you hire a contractor.
Step 1: Prepare your project before you request an estimate
Gathering a consistent set of facts and documents up front both speeds quoting and reduces the risk of cost surprises later. Contractors respond fastest to requests that include address, scope, and deadline, which are the three items Deeroi Constructions asks clients to provide when beginning intake.
Site and contact details
- Project address and unit number, including floor if relevant
- Site contact name, phone and email for scheduling site access
- Typical building hours, loading door locations and any security contacts
Scope and deliverables
Describe what you want delivered, not just what you want removed. For example, "convert retail space to coffee shop with 30 seats, back-of-house kitchen, new millwork counter and new HVAC diffusers" gives far more clarity than "fit out a shop." A clear scope helps contractors include the right trades and avoids scope gaps that become change orders.
Drawings and photos
- Site photos from multiple angles and a few close ups of problem areas
- Floor plans or sketches showing existing conditions and desired walls, counters or fixtures
- Manufacturer or finish PDFs for critical items, like countertops or millwork, if available
Timeline, access and constraints
List your desired start date, any hard completion deadlines and days or hours when work cannot occur. Include parking restrictions, elevator booking needs, noise limits or tenant coordination requirements. The more realistic the timeline details, the better a contractor can plan trade sequencing and give an accurate price.
Budget, funding and permit status
If you have a target budget range, state it. Also note whether permits are already submitted or if you need the contractor to include permit application work. In commercial or institutional work, permit responsibility should be clarified early because it affects both price and schedule.
Step 2: Use a one-page template when you request a construction estimate
Copy and paste this template into an email or a web form. It follows Deeroi Constructions’ simple intake phrasing: provide the address, scope and deadline. Attach photos, sketches and any product specs you have.
One-page request template to copy
Project address: Unit / floor: Building contact for access: Scope summary (brief): Desired deliverables and key finishes: Target start date and hard completion date: Budget target (optional): Permit status: submitted, not started, or owner will obtain Attachments: floor plans, photos, spec sheets Preferred contact for questions:
Use the attachments section to upload photos and a plan. If you need a turnkey restaurant build-out, mention critical items such as millwork, bar counters, lighting and seating so the contractor can include the proper allowances and subcontractors.
Attachments that speed an accurate estimate
- Current plans and proposed layout
- Three to ten photos showing existing conditions
- Finish boards or key product numbers for counters, tile or millwork
- Any engineering or mechanical reports already completed
Step 3: How to submit the request and what to expect next
Most contractors accept requests by email or through a web form with an attachments upload. After you submit, expect a short clarifying exchange, a site visit if needed and then a preliminary or firm estimate depending on how detailed your materials were.
What triggers a site visit
A site visit is common when the work affects structural elements, mechanical or electrical systems, or when access and building rules could materially change cost. If a contractor cannot confirm scope details from your photos or drawings they will schedule a visit before issuing a firm price.
Typical response times and follow up
With clear scope and attachments, preliminary ballpark pricing can arrive in a few business days. A firm, fully scoped estimate usually requires a site visit and takes one to two weeks depending on project complexity and permit questions. Provide availability for a site visit to avoid delays.
Sample questions contractors will ask
- Who is responsible for building permits?
- Are existing utilities active and where are shutoffs located?
- Do you have a preferred millwork supplier or do you want the contractor to source it?
Step 4: Compare estimates line-by-line using clear decision criteria
Not all estimates are directly comparable. A systematic line-by-line review reveals differences in scope, allowances and risk allocation. Well structured contractor quotes help you compare contractors and set clear expectations for scope and schedule, which improves decision making and protects your investment.
For a concise primer on how contractor quotes are structured, see the Canada Construction Network guide to contractor quotes and estimates.
Checklist for comparing competing estimates
- Scope completeness: Does the estimate list every item you asked for, or are key tasks missing?
- Labour versus materials: Are labour hours and material costs separated or bundled?
- Allowances: Are dollar allowances shown for items not yet selected, such as cabinetry or lighting?
- Inclusions and exclusions: What the contractor explicitly includes and what they exclude
- Contingency and change-order terms: Is there a fixed contingency or vague wording allowing unlimited extras?
- Payment schedule and holdbacks: Are deposit amounts reasonable and linked to milestones?
- Timeline and milestones: Are start date and completion milestones included and realistic?
- References and past projects: Are references or relevant portfolio examples provided?
Worked example: three lines to compare
- Demolition: Contractor A itemizes labour and disposal with a unit price per square foot. Contractor B lists a single lump sum without details. The itemized quote is easier to audit and adjust if scope changes. For related first-party details, review bathroom renovations quote.
- Millwork allowance: Verify whether an allowance includes design, manufacture, delivery and installation, or just supply. If only supply is included you will pay separately for installation.
- Contingency: A stated 5 percent contingency that is clearly defined is better than an undefined contingency line. Ask how the contingency will be used and how change orders will be approved.
When reviewing estimates remember that anything not listed specifically in the estimate could become an extra cost later. This principle is reinforced by the Canada Mortgage and Housing Corporation guidance that you should ensure everything you asked for is included and that choosing the lowest price alone is unwise. For authoritative guidance on reviewing contractor estimates in Canada, see the CMHC page on hiring a contractor.
Step 5: Warning signs and contractor questions to protect your budget
Watch for vague language and unusually low prices. The list below identifies common warning signs to address before you commit.
Warning signs to avoid
- Very low price with vague or missing line items
- No itemized breakdown of labour and materials
- Unlimited change-order clauses without a ceiling or approval process
- Large nonrefundable deposits that exceed reasonable mobilization costs
- No references or an inability to show relevant completed projects
- Unclear responsibility for permits, inspections or insurance
Minimum proof to request from bidders
- Two to three references for similar scope work
- Sample contract or terms showing change-order process
- Proof of insurance and basic safety program information
GTA and Ontario considerations when you request a construction estimate
Local rules affect price and schedule. Municipal permit lead times in the GTA vary by city and by permit type. For commercial and institutional work you will also need to account for Ontario Building Code requirements and possible agency plan reviews. Contractors who regularly work across the GTA and Ontario can advise on typical permit timelines and code-conscious execution.
When you request a construction estimate, state whether you expect the contractor to handle permit applications. Clarifying this early avoids later disputes about who pays permit fees or provides required drawings.

Frequently asked questions
What documents speed up a construction estimate?
Site photos, a floor plan or sketch, a scope summary and any product specifications for key finishes speed quoting. If permits are already submitted or drawings exist, include them to avoid follow up questions.
Why do contractor estimates for the same project differ so much?
Differences come from scope interpretation, trade pricing, allowances for unknowns and how contractors allocate risk. One contractor may include design and permit work while another assumes the owner provides it.
Is the lowest estimate usually the best option?
No. The lowest price can hide missing items, inadequate allowances or an approach that increases change orders later. CMHC advises confirming that everything you asked for is included before choosing a bid.
Do contractor estimates include permits and inspections in Ontario?
Not always. Permit responsibility is often an explicit line item or a clarified contract term. State your expectation when you request the estimate so bidders include or exclude permit fees consistently.
How long should I expect to wait for a firm estimate in the GTA?
With clear scope and attachments a preliminary ballpark may arrive in a few days. A firm, scoped estimate that follows a site visit typically takes one to two weeks depending on project complexity and permit questions.
