The largest portion of a painting budget rarely comes from the tin of paint. It comes from the time, expertise, and surface preparation the professional invests before even opening the can. Many property owners are surprised to learn that labour represents, on average, 60 to 70% of the total cost of interior painting, but this weight has technical and economic reasons worth understanding before comparing proposals.
Why labour carries such weight in the final budget
The cost of paint, even when choosing a mid-range quality brand, remains only a small part of the bill. The reason is straightforward: painting is not simply spreading colour on a wall. It involves sanding, filling cracks, protecting floors and skirting boards, applying primer, ensuring uniform finishes, cleaning and returning the space to living condition. All of this requires time and technical skill.
In Portugal, for interior walls, labour costs range between 5 and 15 euros per square metre, excluding materials. When paint and consumables are added, that figure can double. But it is precisely the human labour component that determines whether the paint will peel the first winter or last five years without blemishes.
A two-bedroom apartment with roughly 80 to 100 m² of wall space may have labour costs between 400 and 1,000 euros, depending on surface condition and region. On top of this, paint, primer, filler materials and furniture protection must be added.
What causes labour costs to vary between professionals
Not all labour quotes are the same, even when covering identical areas. The difference lies in what the professional includes in their work. Some charge only for paint application, assuming the client has already sanded, protected and prepared everything. Others include full preparation: crack repair, primer application, two coats of finish and final cleaning.
Professional experience and business structure also matter. An independent painter in Portugal typically charges between 3 and 6 euros per square metre for walls and between 4.50 and 8 euros for ceilings, while a small established company with invoicing and guarantees ranges from 5 to 9 euros per square metre for walls and 7 to 12 euros for ceilings. This difference reflects not only formal guarantee, but also the ability to manage teams, meet deadlines and provide post-work support.
Location is another important variable. In Lisbon and Porto, prices tend to be 15 to 25 percent higher than national averages, reflecting cost of living and demand for qualified professionals in those areas. A quote in Coimbra or Leiria may be considerably lower than identical work in Lisbon, without implying lower quality.
How to interpret a quote that separates labour from materials
When a professional presents a quote divided into labour and materials, they are giving the property owner the freedom to choose paint and assume the risk of quantity and quality. This can be advantageous if the client knows the product well or already has paint on hand. But it carries risks.
If the calculated paint quantity falls short of what is needed, work may stall. If the quality is unsuitable for the surface - for example, paint without humidity resistance in a bathroom - the result will disappoint. And if the primer is not compatible with the finish, stains or peeling may appear.
Conversely, a quote that includes everything - labour and materials - transfers technical responsibility to the professional. They select appropriate paint, calculate the correct quantity, ensure primer and finish work together. This approach is safer, especially for those with no previous painting experience.
On our platform, all work details are recorded online, including whether the quote covers only labour or also materials. The property owner, professional and platform can all see what was agreed, avoiding misunderstandings during execution.
Preparation is invisible work, but it weighs on the budget
Most of the time a painter spends on site is not painting. It is preparing. Sanding old walls, filling nail holes, filling cracks, applying levelling filler, protecting window frames, covering floors, removing furniture or relocating what cannot leave the room. All of this consumes hours and requires technical skill.
In an older apartment in Lisbon or Porto, where walls have decades of accumulated paint, structural dampness and fine cracks, preparation may occupy half the total project time. In a newer apartment in Aveiro or Braga, with fresh, well-rendered walls, preparation is minimal and focus goes straight to finishing.
This is why two quotes for the same area can present very different values. The professional who visited the location - or received detailed photos and videos - can estimate the actual work required. Anyone presenting a generic price per square metre without assessing surface condition is guessing, and that rarely ends well.
Our platform always requests photographs and videos of surfaces before finalising any quote, precisely so the professional can anticipate necessary preparation and avoid mid-project adjustments.
Comparing quotes requires checking what is included
A common mistake is choosing the lowest quote without understanding what it covers. If one proposal shows 6 euros per square metre and another shows 10 euros, the difference may be that the first covers only two paint coats on already-prepared walls, while the second includes sanding, primer, crack repair, space protection and final cleaning.
To compare fairly, you need to know:
- Whether the quote includes labour only or also materials.
- How many paint coats are planned.
- Whether surface preparation is included or considered extra work.
- Whether furniture, floor and window frame protection is part of the service.
- Whether final cleaning is covered.
On our platform, the payment model is always the same: 50% at the start (to reserve the date and purchase materials) and 50% at the end, after verification of completed work. This model protects both parties and ensures the property owner pays in full only after confirming everything matches what was agreed.
What to do before accepting a labour quote
Before accepting any proposal, it is worth having a clear idea of what the work involves. If the professional has not yet seen the space - either through photos and videos or in person - the quote is provisional. Two apartments with identical area can have completely different needs if one has new walls and the other has dampness, cracks and three layers of old paint.
Asking what is included in the price is not distrust, it is planning. Knowing whether the professional will apply primer, how many coats are planned, whether they will protect the floor and whether final cleaning is included helps avoid surprises at the end.
Our platform always verifies that the professional is registered as a self-employed worker or has an incorporated company before presenting them as an option. This ensures whoever executes the work operates within the law, can issue invoices and assume formal responsibilities to the client and platform.
Comparing quotes thoughtfully, understanding labour's weight and knowing what each proposal truly covers are essential steps to transform a painting project into an informed decision, not a gamble.
