How much does it cost to paint a house in the Algarve?

Start with an area that can be explained

Exterior wall area can be estimated from dimensions, plans or a mapped building footprint, then adjusted for height and openings. Interior work is clearer room by room: walls, ceilings, doors and trim should not be mixed into one undefined figure.

A useful estimate states the source of the area and what has been deducted or added. If the dimensions are uncertain, the range should remain wider until they are checked.

• Known wall measurements or building footprint
• Number of storeys and approximate height
• Doors, windows and areas excluded
• Whether ceilings, trim, shutters or gates are separate

Preparation is the biggest variable

Sound, clean paint may need limited preparation. Peeling coating, open cracks, salts, algae, failed sealant or friable render require more stages and drying time. Those stages should appear in the scope instead of being hidden inside a generic price per square metre.

Colour change and coating system also matter. Product coverage is measured under stated conditions; rough or absorbent surfaces and extra coats change real consumption.

Access, protection and timing complete the price

Scaffolding, difficult parking, narrow side access, occupied rooms, pool protection and work between guest bookings affect labour and sequencing. A low rate can become a poor comparison if these conditions are excluded.

Use the online calculator for a planning range, then send location, photographs and known measurements. The final scope should identify assumptions, optional items and what requires a site visit.
