How Much Does It Cost to Paint a House Exterior?

Exterior house painting is a significant investment, but getting the budget wrong — either overspending on unnecessary preparation or underestimating scaffolding and labour — can turn a straightforward project into a stressful one. This guide breaks down every cost involved so you can plan accurately, whether you are painting the house yourself or hiring professionals.

Our cost calculator uses your house dimensions and surface type to estimate both material costs and professional labour, giving you a clear picture of DIY versus contractor pricing.

Cost Breakdown by House Type

The total cost of painting a house exterior depends on its size, the number of walls to paint, surface condition, and whether you need scaffolding. Here are realistic 2026 figures for a full exterior repaint with 2 coats of quality masonry paint.

DIY costs include paint, primer, pressure washer hire, fillers, brushes, rollers, and masking materials. Professional costs include all materials, labour, scaffolding, and preparation.

DIY vs Professional: Detailed Cost Comparison

This table compares the full itemised cost of painting a typical semi-detached house (110 m² wall area, smooth render, 2 coats) as a DIY project versus hiring a professional team.

The DIY route saves EUR 800-2,200 in labour but requires 4-7 days of work, comfort with heights (ladder or scaffold work), and the physical stamina for long days of overhead painting. If scaffolding is already needed for another job (roof repairs, guttering), combining projects saves the setup cost.

Cost Per Square Metre Breakdown

Understanding cost per square metre helps you compare quotes from different painters and benchmark your own budget.

When comparing professional quotes, ask whether scaffolding is included or charged separately. Some painters hire scaffolding through a preferred supplier, while others add a markup.

What Affects the Price

Several factors can push the cost up or down from the averages above.

Surface condition is the biggest variable. A house with sound existing paint that just needs a wash and two fresh coats is the cheapest scenario. A house with flaking paint, cracks, and algae growth needs extensive preparation — scraping, filling, treating, and priming — which can add 30-50% to labour time.

Building height directly impacts scaffolding cost. A single-storey bungalow may only need ladders (EUR 0-50 hire), while a three-storey townhouse requires full scaffold towers (EUR 800-1,500). For two-storey houses, basic scaffold is usually EUR 400-800 for a week.

Surface type matters because rough and porous surfaces take longer to paint and use more material. Painting pebbledash render costs 15-25% more than smooth render due to the extra paint needed to fill the textured surface and the slower roller speed.

Access difficulty increases cost when walls border narrow alleyways, conservatories, fragile garden beds, or sloped ground that complicates scaffold placement.

Number of colours adds to the labour. A single-colour job is simplest. If you want different colours for walls, window surrounds, fascias, and soffits, each colour change requires masking and cleanup time.

How to Save Money on Exterior Painting

You can significantly reduce costs without compromising quality:

• Do the preparation yourself — Even if you hire painters for the application, doing the pressure washing, scraping, and filling yourself can save EUR 300-600 in labour. Painters will often reduce their quote if the surface is ready to paint.
• Paint in the off-season — Painters are busiest May through September. Booking for early spring or late autumn can secure a 10-20% discount, provided the weather cooperates.
• Buy paint in bulk — Trade paint from builders' merchants costs 20-30% less than retail paint from DIY stores. A 10L tin is always cheaper per litre than 2.5L tins.
• Combine with other work — If you already need scaffolding for gutter replacement, roof repairs, or window work, add exterior painting to the same scaffold hire period.
• Use quality paint — This sounds counterintuitive, but premium masonry paint (EUR 7-10/L) with a 15-year guarantee costs more upfront but lasts 2-3 years longer than budget paint (EUR 3-5/L), saving a full repaint cycle.

When to Hire a Professional

Hire a professional exterior painter when the job involves work at height above one storey, extensive surface repairs, lead paint removal (pre-1970s houses), or when you simply want a guaranteed finish in a short timeframe. A professional team of 2-3 painters can complete a semi-detached house in 2-3 days, whereas a solo DIYer may take a full week.

Use our free quote tool below to get competitive estimates from local exterior painters. We recommend getting at least 3 quotes and asking each painter to itemise scaffolding, preparation, materials, and labour separately so you can compare like for like.

Budgeting Checklist

Before starting your exterior painting project, confirm you have budgeted for every item:

• Scaffolding or ladder hire
• Pressure washer hire (or professional wash)
• Exterior filler, caulk, and mastic for cracks
• Masonry primer or stabilising solution
• Masonry paint (2 coats minimum)
• Rollers (long-nap for masonry), brushes, extension poles
• Masking tape, plastic sheeting, dust sheets
• Skip hire or waste disposal for old flaking paint
• Contingency (add 10-15% for unexpected repairs)
