What's Included in an Interior Painting Quote

A good interior painting quote names every surface being painted, the prep work for each, the paint product and number of coats, the schedule, the payment terms and what is left out. If a quote is a single number on a page, you can’t tell what you are buying, and you can’t compare it with anything. This guide walks through each line a complete quote should carry, what Ontario rules say about estimates, and the questions to ask before you sign.

TL;DR

• A complete quote lists surfaces room by room (walls, ceilings, trim, doors, closets), the prep, the paint brand and sheen, and the number of coats.
• Exclusions matter as much as inclusions. If it is not written down, assume it is not covered.
• In Ontario, a final price cannot be more than 10% over a written estimate included in your contract unless you agree to new work or a new price.
• Check insurance, WSIB clearance, deposit size and payment milestones before work starts.
• Compare quotes line by line, not by the bottom number.

Why the quote is the most important document in the job

A painting quote is more than a price. It is the written description of the work, and it is what both sides will point to if something is disputed halfway through. Ontario’s guidance for consumers says estimates should describe the work and list products and services with their prices, and it recommends getting at least three written estimates from different contractors.

The same page is clear on how a written estimate protects you. Where an estimate is part of a renovation contract, the final price cannot exceed it by more than 10% without your agreement. The business guide to the Act says the same thing from the contractor’s side: you cannot bill a consumer more than 10% above the estimated price unless the consumer agrees to the extra charges in writing.

That protection is only as strong as the estimate is specific. A vague quote gives a vague limit. A detailed one gives you something to hold the contractor to, and gives us something to hold ourselves to.

The measuring visit comes before the quote

Before any numbers appear, a painter should walk the house. A trustworthy estimate starts with someone measuring rooms, writing down wall and ceiling areas, and looking at the surfaces in good light. Guidance for hiring a painter in Ontario warns that pricing from the doorway is guessing, and that the guess usually carries a cushion for being wrong.

What a proper visit covers:

1. Measuring every room, walls and ceilings separately.
2. Checking walls under raking light for dents, nail pops, cracks and old patches.
3. Noting the existing finish, such as glossy trim, oil-based paint, stains or water marks.
4. Asking about colour changes, since going from dark to light takes more coats.
5. Asking about furniture, flooring, occupied rooms and access.

If you get a number by text from photos alone, treat it as a rough range, not a quote.

Line by line: what a complete quote should include

1. Scope by room and surface

The quote should list each room and each surface in it. “Paint main floor” is not a scope. Look for something like this for every room:

• Walls: yes or no
• Ceilings: yes or no
• Baseboards, casing and crown moulding
• Doors and door frames (both sides, and edges)
• Closets (inside as well as the door)
• Railings, spindles, built-ins, window sills

These items are where quotes differ most. Two painters can both say “interior painting” and one has priced only the walls. Ceilings, trim, doors and closets each add time, which is why they should appear as their own lines.

Ceiling height also changes the price. Cost guides note that ceilings above the standard 8 to 10 feet can add 20% to 40% because of scaffolding, extension poles and added safety labour. If you have a vaulted entry or a two-storey stairwell, the quote should say how it is being reached and priced.

2. Surface preparation

Prep is where a good paint job is made, and it is the line most often left vague. A quote should say what is included, for example:

• Filling nail holes, dents and small cracks
• Caulking gaps at trim and corners
• Sanding patched areas and glossy surfaces
• Spot priming or full priming
• Washing walls in kitchens and bathrooms
• Masking and protecting floors, fixtures and furniture

Be specific about the size of repairs. Light patching is often part of the base price, but larger drywall repair is a different job with different steps: cut-out, new board, taping, multiple coats of compound, sanding and priming. If you have water damage, holes from removed shelving or old textured ceilings, ask for those repairs as a separate line. We cover that in more detail in our guide to drywall repair and interior painting in Bowmanville.

3. Paint product, sheen and coats

A quote should name the paint brand and product line, the sheen for each surface type, and the number of coats. Typical practice is a primer where needed plus two finish coats, with extra coats for dramatic colour changes.

Why this matters: paint is not one product. A contractor can price a builder-grade flat paint or a premium washable line, and the labour is nearly the same. If the quote only says “paint,” you can’t tell which one you are getting. Ask for:

• Brand and line (for example, the specific product name)
• Sheen for walls, ceilings and trim
• Colour names or codes, or a note that colours are to be confirmed
• Whether the contractor or you supply the paint

If you are choosing colours, it also helps to know who is paying for samples and whether sample pots are included.

4. Labour, materials and HST

Ask for labour and materials to be shown clearly, whether as separate lines or as a clearly itemized total per area. The contract should also show the business name, contact details and HST. If subcontractors are working on your job, they should be listed.

Be cautious about square-foot rates. A rate per square foot of floor area can be useful for rough budgeting, but it hides differences in ceiling height, number of doors, amount of trim and condition of walls. Use it to sanity check, not to compare.

5. Schedule and payment terms

A quote should give a start date, an estimated completion date and how the work is sequenced. For a whole-house job, that means which rooms come first and when you need to move furniture or stay out of a room.

Payment terms should be tied to progress, not just dates. Contractor guidance suggests a deposit of 10% or less, and never more than the cost of materials, with larger multi-room jobs paid in milestones such as priming, first coat and final walk-through. The provincial consumer page also warns against large down payments as a common sign of trouble.

A good schedule section reads much like the one in any specification document: it says what happens, in what order, and what triggers each payment. Even a guide on contracts and specifications for custom wall murals makes the same point about confirming schedule and payment details before work begins, and that applies equally to a painting job.

6. Insurance, WSIB and warranty

The quote or contract should confirm that the contractor carries liability insurance and is covered by WSIB. Hiring guidance for Ontario says to verify the WSIB clearance certificate on the WSIB website before work begins, since without valid coverage you could be treated as the employer if someone is hurt. It also suggests confirming at least $2 million in liability coverage, which is what protects your hardwood if a can of paint is dropped.

Also look for a written workmanship warranty: how long it lasts, what it covers (peeling, blistering, poor adhesion) and what it does not (new water damage, impact marks).

7. Exclusions and assumptions

This is the section most quotes skip, and the one that prevents most arguments. The Ontario consumer guidance is blunt that everything agreed should be in the contract. In practice, if it isn’t written, assume it isn’t included.

Good exclusions say things like:

• Moving heavy furniture, or who moves it
• Painting inside closets, or not
• Removing wallpaper or popcorn ceilings
• Repairs beyond a stated size
• Painting over mould, which needs to be dealt with first
• Work on walls hidden behind items you have not cleared
• Extra coats for colour changes beyond what was quoted

Exclusions are not a sign of a contractor hiding things. They are a sign of one who has thought about the job.

What the Ontario rules mean for your quote

Three points are worth knowing before you sign.

Written agreement. Provincial guidance for renovation businesses states that any contract worth more than $50 must be in writing. A handshake on a painting job is not enough.

The 10% limit. If the estimate is part of the contract, the final price cannot go more than 10% over it unless you agree to new work or a new price. This is why you should insist that the written estimate is attached to the contract itself.

Changes in writing. If new work comes up, such as discovering a damaged wall behind a cabinet, the contractor should discuss it with you and ask you to approve and sign a change to the contract, including a new estimate.

The province also describes a cooling-off period for some contracts signed at your home. Read the details on the official consumer page to see how it applies to your situation. If you are unsure about your rights in a dispute, the Ontario government’s consumer resources or a lawyer are the right place to start, not a contractor’s website.

How to compare two or three quotes fairly

Put the quotes side by side and build a simple table. Here is a template you can copy.

Fill in what each quote actually says, not what you assume. Blank cells tell you where to ask questions. The cheapest quote often has the most blanks, and the difference usually comes back as a change order later.

For local context, our guides to comparing interior painting quotes in Bowmanville and the written scope to expect from interior painters go deeper on the same checks. For a budget range, our page on the cost to paint a 1,500 to 2,000 sq. ft. Bowmanville home puts it at $6,000 to $15,000, and our Durham Region painting cost guide explains how a contractor builds that number.

Red flags in a painting quote

• A price with no measurements. If nobody measured, nobody priced.
• “Paint and labour” as one line. You can’t verify anything.
• A large deposit. A request well above 10%, or above the cost of materials, deserves a question.
• No mention of prep. Either it’s not being done or it’s being left to chance.
• No insurance or WSIB details. Ask for the certificate, then check it yourself.
• Pressure to sign today. A fair quote will still be fair tomorrow.
• A price far below the others. Look for what has been left out: coats, trim, ceilings or prep.

Our view: a quote should read like a plan

We are a locally owned, fully insured renovation contractor serving Bowmanville, Clarington and communities across Durham Region, and we paint a lot of interiors. Our view is simple: a quote should read like a plan for the work. When you finish reading it, you should know which rooms, which surfaces, what prep, what paint, when, and for how much.

The reason we write it that way is practical. Most disputes on painting jobs come from a gap between what the homeowner pictured and what the paper said. Closets, ceilings, trim and drywall patches are the usual gaps. Writing them down at the start costs us a few extra minutes and saves both sides a conversation nobody enjoys later.

We also think the best quotes come from standing in the house. We would rather measure, look at the walls in daylight and flag a damaged corner before we give a number than send a figure we may have to revise. That is how transparent pricing works in practice: the price is connected to things you can see on the page.

If you are comparing us with other painters, hold us to the same checklist as everyone else. A contractor who is confident in the work will welcome it.

FAQ

What should a painting quote include?

It should include the rooms and surfaces being painted, the prep work, the paint brand and sheen, the number of coats, labour and materials, HST, start and finish dates, payment terms, insurance and WSIB details, warranty and a list of exclusions. Ontario guidance says estimates should describe the work and itemize products and services with prices.

Is a painting estimate legally binding in Ontario?

If an estimate is included in your home renovation contract, the final price cannot be more than 10% above it unless you agree to new work or a new price. That is why you should insist the written estimate is part of the contract. Any contract over $50 should be in writing.

How much deposit is reasonable for interior painting?

Contractor guidance for Ontario says 10% or less, and never more than the cost of materials, is a reasonable deposit on a standard job. For larger multi-room projects, ask for payments tied to milestones such as priming, first coat and final walk-through.

Does a painting quote include moving furniture and patching walls?

Not automatically. Some contractors include light patching and moving furniture to the centre of the room, and others charge for it. Check that your quote says what is covered and where the limit is, such as the size of repairs, and ask for larger drywall repairs as a separate line.

Why do two painting quotes for the same house differ so much?

Usually because the scope differs. One may include ceilings, trim, doors and closets, two coats of premium paint and thorough prep, while the other covers walls only. Compare the line items before you compare the totals.
