Exterior House Painting: A Practical UK Homeowner’s Guide
A fresh exterior paint job can make a home look properly cared for again. It can also help protect timber, masonry and metalwork from the British weather. The important word there is help: paint is not a cure for failed gutters, damp walls or rotten joinery. A good decorator will deal with the preparation first, then apply a suitable coating system.
Whether you are brightening tired render, repainting window frames or giving the whole front elevation a new look, this guide will help you plan the job, compare quotes and avoid the usual expensive shortcuts.
What does exterior painting usually include?
The scope varies hugely between a small porch and a full detached house, so ask every decorator to describe exactly what they have allowed for. Exterior work commonly includes:
- Washing down and removing loose dirt, algae and flaking paint
- Scraping, sanding and feathering failed edges
- Minor repairs to cracks, timber or masonry where agreed
- Spot priming bare timber, metal or repaired areas
- Masking and protecting paths, windows, plants and brickwork
- Applying the specified undercoat and top coats
- Safe access equipment, such as ladders, towers or scaffolding
- A final tidy-up and removal of waste
“Paint exterior” is not enough detail for a useful quotation. The preparation, access and number of coats often make more difference to the final price than the paint itself.
Choose the right time of year
Late spring through early autumn is usually the easier window for exterior decorating, but dry conditions matter more than the month on the calendar. Paint needs the surface to be dry and the temperature to sit within the manufacturer’s guidance. Cold nights, rain, heavy dew and very strong sun can all affect how it dries and bonds.
A sensible decorator will watch the forecast rather than promise to paint through unsuitable weather. It can feel frustrating if a job pauses for a day or two, but rushing paint onto a damp surface is a false economy.
Which surfaces need different treatment?
| Surface | What to check first | Typical approach |
|---|---|---|
| Render or painted masonry | Cracks, hollow areas, damp staining and algae | Clean, repair compatible cracks, stabilise where needed, then use a breathable exterior masonry paint. |
| Timber windows, doors and fascias | Rot, open joints, peeling paint and failed sealant | Repair or replace unsound timber, sand back loose coatings, prime bare areas and use a suitable exterior wood system. |
| Metal railings and gates | Rust, loose paint and water traps | Remove loose rust, treat and prime bare metal, then apply a compatible exterior metal paint. |
| Brickwork | Whether it should be painted at all, plus damp or spalling bricks | Seek advice before coating previously unpainted brick; repairs and moisture issues should be addressed first. |
Preparation is where the job is won
Fresh paint can make poor preparation look acceptable for a short while. Then the bubbles, peeling edges and cracks return. Before accepting a quote, ask how the contractor plans to prepare each surface.
For timber, that may mean cutting out decayed sections or using a proper repair system rather than painting over soft wood. For masonry, it may mean dealing with loose render and filling stable hairline cracks. If paint has repeatedly failed in one area, look for the reason: overflowing gutters, leaking pipes, failed flashing or trapped moisture may need another trade before decorating begins.
Be wary of quotes that include “two coats” but say nothing about washing, scraping, sanding, priming or repairs. The coat count only means something when the surface is ready to receive it.
How much does exterior house painting cost?
Costs depend on the size and condition of the property, the height of the work, the paint system, the amount of repair work and local labour rates. As a broad planning guide, repainting the front of a small, straightforward terraced or semi-detached home may run from around £1,000 to £3,000. A larger house, extensive timberwork, difficult access or scaffolding can push the project well beyond that.
These are cautious budget ranges, not fixed prices. A home with peeling render, rotten fascias or access over a conservatory needs a different allowance from a recently painted house with easy ground-level access. Obtain written quotes based on a visit wherever possible.
Paint choices: do not select on colour alone
Most homeowners start with the colour, which is understandable. But the product needs to suit the surface and exposure as well. A north-facing wall with algae growth has different demands from a sheltered sunny elevation. Timber needs flexibility and good edge coverage; masonry often benefits from a breathable coating; metal requires sound rust preparation and compatible primers.
Ask the decorator to name the products they propose using, including primers and undercoats. This makes it easier to compare quotes fairly and gives you a clear record for future maintenance. If you are choosing a bold shade, consider a tester patch and look at it in daylight, shade and evening light before committing.
Access, neighbours and practical planning
Exterior work is less disruptive than a full internal renovation, but it still needs organising. Move garden furniture and vehicles away from the working area. Tell the decorator about side access, pets, fragile plants, conservatories and any shared paths or boundaries.
Scaffolding may be the safest and most efficient option for upper-storey work, especially around eaves and awkward roofs. It costs more than a ladder, but it can improve access and the quality of preparation. Check whether the quote includes it, how long it will remain in place and whether permits are needed if equipment affects a public pavement.
Questions to ask before appointing a decorator
- What preparation and repairs are included, and what would be charged separately?
- Which paint system and colours are included?
- How will you protect windows, paths, plants and neighbouring property?
- Is access equipment included in the price?
- How will weather delays be handled?
- How long do you expect the work to take?
- Can you show examples of similar exterior work?
- What payment schedule do you propose?
Frequently asked questions
How often should a house exterior be painted?
There is no single timetable. Exposure, surface type, paint quality and previous preparation all matter. Inspect the exterior each year for peeling paint, open joints, bare timber, cracks and water staining rather than waiting for a fixed number of years.
Can exterior painting be done in light rain?
It is generally best avoided. Surfaces need to be suitably dry, and rain can mark fresh coatings or affect adhesion. Follow the paint manufacturer’s conditions and let the decorator make a weather-led decision.
Should I repair cracks before painting?
Yes, but the cause matters. Small stable cracks may be suitable for repair as part of preparation. Wider, recurring or damp-related cracks should be assessed before they are simply filled and painted.
Do I need a specialist for listed buildings?
Potentially. If your property is listed or in a conservation area, check what controls apply before changing exterior finishes or colours. A contractor experienced with traditional materials can be especially valuable.
Final checklist
- Agree the surfaces, preparation, repairs, paint products and colours in writing.
- Compare like-for-like quotes, including access equipment and VAT where applicable.
- Address leaks, gutter problems and serious damp before decorating.
- Keep a small labelled pot of the final colour for future touch-ups.
- Inspect the work in good daylight before making the final payment.
