Fresh, well-applied paintwork creates an impression of care and quality, enhancing kerb appeal and contributing positively to property values. Tired, peeling, or faded paintwork does the opposite, making even well-maintained properties appear neglected.
The second purpose is perhaps more important though less immediately visible. Exterior paint forms a protective barrier between your building fabric and the relentless assault of weather. It blocks moisture penetration that would otherwise soak into masonry and render, causing damp problems, promoting mould growth, and leading to frost damage in winter. It reflects ultraviolet radiation that degrades unprotected surfaces over time. It provides a sacrificial layer that weathers instead of the underlying substrate.
When exterior paintwork fails - cracking, peeling, chalking, or simply wearing thin - that protective function diminishes rapidly. Water finds its way through minute gaps that would be invisible to casual observation. Once moisture enters your walls, problems multiply. Damp patches appear internally. Mould grows in hidden cavities. Plaster loses adhesion and blows. Timber window frames rot from the inside. The cost of addressing these consequent problems far exceeds what timely repainting would have cost.
JB Contractors delivers professional exterior painting services across Plymouth, Truro, Falmouth, and throughout Cornwall. We have painted hundreds of properties over fifteen years, from small terraced cottages to substantial detached houses, from contemporary renders to historic lime-washed walls. Each project has taught us something valuable about achieving lasting results in our challenging climate.
Our approach combines thorough preparation with premium materials and skilled application. We understand that proper preparation takes time but makes the difference between paintwork that lasts years and paintwork that fails within months. We use paints specifically formulated for exterior use in British weather, selecting products that balance durability, breathability, and visual appeal for each specific application.
If you have ever seen paint peeling from a wall just a year or two after application, inadequate preparation was almost certainly the cause. Paint can only adhere to clean, stable surfaces. Applying even the finest paint over dirt, loose material, biological growth, or incompatible previous coatings guarantees premature failure. That is why we invest significant time in preparation, often spending more time preparing surfaces than actually painting them.
Our preparation process begins with thorough cleaning. For most exterior surfaces, this means professional pressure washing to remove accumulated dirt, pollution, algae, moss, and other contamination. We use appropriate pressure settings and techniques for different substrates, avoiding damage while achieving thorough cleaning. Surfaces then dry completely before any further work proceeds.
With clean surfaces, we address any defects. Cracks in render require proper filling with appropriate materials that flex with the substrate rather than creating rigid bridges that will crack again. Areas of blown or loose material must be removed and made good. Previous paintwork that has failed needs scraping back to sound material, with edges feathered to avoid visible steps in the finished work. Bare substrates require appropriate primers to ensure proper adhesion of finish coats.
We also address related issues that affect paintwork longevity. Defective guttering that allows water to cascade down walls, pointing failures that admit moisture, and render damage that compromises the substrate all need attention before painting. There is little point in applying beautiful paintwork over problems that will cause it to fail prematurely.
Rendered walls, pebbledash, exposed brick, and stone all require appropriate treatment. We use microporous masonry paints that allow moisture vapour to escape from within walls while blocking liquid water penetration from outside. This breathability is essential, particularly for older solid-walled properties without cavity construction. We serve all areas including Camborne, Redruth, Hayle, and throughout west Cornwall.
Exterior woodwork faces particular challenges. Timber expands and contracts with moisture changes, requiring flexible coating systems that move with the substrate. We properly prepare all timber surfaces, treating any rot, applying appropriate primers, and using exterior wood paints or stains designed for long-term performance. Fascias, soffits, barge boards, window frames, doors, and decorative features all receive appropriate treatment.
Railings, gates, guttering, downpipes, and other metal elements require specific preparation and coating systems. We remove rust mechanically and chemically, apply rust-inhibiting primers, and finish with paints formulated for metal substrates. Proper treatment prevents corrosion returning and extends the useful life of metalwork significantly.
Many clients choose comprehensive exterior decoration covering all elements in a coordinated scheme. This approach ensures colour harmony, proves more cost-effective than addressing elements separately over time, and transforms property appearance completely. Popular throughout Newquay, Padstow, and coastal areas where salt exposure demands regular maintenance.
Cornwall's climate is notoriously demanding on exterior finishes. High humidity, frequent rain, salt-laden coastal air, strong ultraviolet exposure during summer months, and freeze-thaw cycles during winter all test paintwork continuously. Not all paints cope equally with these conditions.
We specify and use premium exterior paints from manufacturers who understand our climate and formulate products accordingly. These paints offer exceptional adhesion that maintains bond through repeated wetting and drying cycles. They provide flexibility to accommodate substrate movement without cracking. They resist ultraviolet degradation that causes cheaper paints to chalk and fade. They maintain their protective properties and appearance for years rather than months.
The price premium compared to budget alternatives is modest when set against the total cost of an exterior painting project. The performance difference is substantial. Cheap paint that fails within two years costs far more than quality paint lasting five or more years, even before considering the inconvenience and visual impact of premature failure.
We advise on appropriate products for your specific situation. Properties in exposed coastal locations like St Ives, Penzance, and Bude face different challenges than sheltered inland properties in Bodmin or Launceston. South-facing elevations receiving intense sun need different consideration than shaded north walls. We match products to conditions for optimal results.
Consider combining exterior painting with our other services. Render repairs ensure a sound substrate. Weather shielding treatments provide additional protection. New fascias and guttering New Roof Installation complete the transformation. Roofing work addresses the most critical element of your property's weather envelope.

Exterior painting is one of the easier trades to budget for, because the cost tracks the wall area fairly closely. Published UK averages put it at around £30 per square metre all in. Here is roughly what that means for a whole house.
| Work | Typical UK cost | Notes |
|---|---|---|
| Painting a house exterior, per m² | £20 – £40 | around £30 on average |
| Terraced house, around 40m² | £800 – £1,600 | typically about £1,200 |
| Semi-detached, around 90m² | £1,800 – £3,600 | typically about £2,700 |
| Detached, around 120m² | £2,400 – £4,800 | typically about £3,600 |
| Painter and decorator day rate | £220 – £400 | around £27.50 – £50 an hour |
| Masonry paint, materials | around £300 | for an average semi |
| Stabilising primer or sealing coat | around £260 | needed on chalky or previously unpainted render |
| Scaffolding or access | from around £330 | depends on height and frontage |
Where these figures come from. Figures are published UK industry averages from Checkatrade’s cost guides, reviewed August 2026. They are national ranges for guidance only — not a quotation from JB Contractors, and not specific to the South West. Every property differs. The only accurate number is the one on a written quote after we have seen the job.
Bare or previously unpainted render needing a stabilising coat, extensive crack repair before painting, three storeys, heavy detailing around windows, and colour changes that need an extra coat.
Sound existing paintwork, a like-for-like colour, single-storey or accessible elevations, and combining the job with other exterior work while the access is already up.
Standard masonry paint struggles on exposed coastal elevations. On a seafront or hilltop property, a breathable or elastomeric system costs more up front and lasts considerably longer — usually the cheaper decision across ten years.
“After two disappointing experiences with other contractors, finding JB Contractors restored our faith in the trade. Excellent communication from start to finish, work completed exactly as quoted, and a beautiful exterior painting job on our Victorian terrace. Genuinely outstanding service.”
