Why Do House Painting Quotes Vary So Much?

You asked three painters to quote the same job. The quotes came back at $6,500, $9,200 and $14,000. Same house, same rooms, same surfaces. How is that possible?

It happens all the time — and the variation is almost never explained. Most homeowners are left guessing whether the expensive quote is overpriced or the cheap one is a risk. Understanding painting quote differences is one of the most useful things you can know before booking a painter.

Painting quotes vary because they include different things. A quote is not a price for paint on walls. It is a price for a defined scope of work.

The Short Answer

Painting quotes vary because they include different things. Two quotes for the same property can differ by thousands of dollars depending on what preparation is included, whether repairs are scoped, which coating system is specified, how many coats are proposed, and who will actually do the work.

A quote is not a price for paint on walls. It is a price for a defined scope of work, and when the scopes differ, comparing prices directly is comparing apples and oranges.

What Drives the Gap: The Five Main Variables

1. Preparation scope

Preparation is the largest variable in any interior or exterior paint job. It is also the most frequently cut when a painter is trying to produce a cheaper quote.

A proper interior preparation scope includes patching holes and cracks in plaster, sanding surfaces to a smooth finish, cleaning contaminated areas, treating mould staining before painting, sealing water stains, and priming bare or repaired sections before applying any topcoat. A minimal preparation scope fills obvious holes and applies paint over the rest.

Both result in a freshly painted surface on the day. The difference becomes visible within 12–24 months when cracks reappear through the paint, mould bleeds through, water stains ghost back through the new coat, or paint adhesion fails in areas that were not properly primed.

Preparation can account for 50–70% of the time on a well-executed paint job, depending on surface condition. A quote that skips or minimises preparation is not the same job at a lower price — it is usually a shorter-lived result.

2. Repairs included or excluded

Many quotes for houses in South East Melbourne’s established suburbs exclude repairs entirely. The quote covers painting only — any plaster repairs, crack filling, timber repairs or surface correction are treated as separate items to be quoted and charged after the painter has started work.

This is the most common source of “scope creep” complaints in the painting industry — the quote looked reasonable, but by the end of the job, the cost had increased significantly as repairs were added.

A quote that includes an on-site surface assessment and scopes repairs upfront will look more expensive than one that simply quotes to paint. The difference is that the higher quote reflects the actual cost of doing the job properly, while the lower quote is the initial number before the real cost becomes clear.

3. Coating system specified

A two-coat application of premium exterior paint costs more in materials than a single coat of mid-range product. Premium exterior coatings — such as Dulux Weathershield, Haymes Solashield and equivalent systems — generally cost more than budget products, but they are designed for longer exterior performance when the surface is prepared and applied correctly.

For many exterior repaints, the total material cost difference between budget and premium coating systems may be smaller than the labour difference. The bigger issue is performance: a cheaper coating system can look more competitive up front but require attention sooner, especially on exposed surfaces.

A professional quote should specify the coating system — manufacturer, product name and number of coats — so you can see exactly what is being applied.

4. Who is doing the work

Many painting companies operate as a booking and quoting operation — they quote the job, take the booking, and then pass the work to subcontractors. The subcontractors are typically paid a rate that leaves them little margin for thorough preparation or careful workmanship.

A painter who quotes low to win the job and then passes it to the cheapest available subcontractor has no personal stake in the quality of the result. There is no continuity between the person who inspected the property and the people who show up to paint it.

A family-owned or directly-employed team where the same people who quote also carry out the work has a direct reputational interest in every job they do. This structure typically costs more — and produces a meaningfully different result.

5. Insurance and compliance

A properly insured painter with public liability cover costs more than an operator who is not carrying the same compliance costs. Insurance, professional memberships, safe work practices and business overheads are real expenses that are reflected in professional quotes. If an uninsured or poorly covered operator damages your property, resolving the issue can become much harder.

How to Actually Compare Painting Quotes

When you receive multiple quotes, the comparison that matters is not price — it is scope.

• What preparation is included in this quote?
• Are plaster repairs, crack filling and priming included, or quoted separately?
• What coating system are you using — manufacturer, product name, and number of coats?
• Will your own employees be doing the work, or will it be subcontracted?
• What does the workmanship guarantee cover and for how long?

A quote that answers all of these clearly, in writing, is a fundamentally different product from one that says “painting of interior — $6,500” with no further detail.

The $6,500 quote may cover two coats of paint applied over whatever surface exists. The $9,200 quote may cover crack repairs, plaster patching, priming, two coats of premium product and a written workmanship guarantee. These are not the same job.

The Honest Summary

Cheap quotes are cheap because they exclude things — preparation, repairs, quality coating systems, insurance, or the accountability that comes with a directly employed team. The exclusions are not always visible in the quote document, which is why comparing painting quotes based solely on price is genuinely misleading.

The question to ask is not “which quote is cheapest?” It is “which quote is actually scoping the job I need done — and doing it in a way that will hold up?”

Frequently Asked Questions

Why are painting quotes so different for the same job?

Because they include different things. Preparation scope, repairs, coating system quality, number of coats and who does the work all vary significantly between quotes — even for the same property.

How do I know if a painting quote is good value?

Compare the scope, not the price. Ask what preparation is included, whether repairs are scoped up front, which coating products are specified, and who will do the work. A detailed written quote with clear inclusions is a better product than a low price with a vague scope.

Should I always choose the cheapest painting quote?

No. A cheap quote that excludes preparation or uses a lower-quality coating system will cost more in the medium term — either repainting sooner or paying to fix preparation failures. The lowest-priced quote is often the most expensive option over a 5–10 year horizon.
