- Hairline crack filling and surface repairs before painting
- K-Rend and polymer render repainting
- Lime render on period and listed properties
- Biological growth treatment for algae and moss on north-facing elevations
Smooth and sand-faced render appears on interwar and post-war estates, roughcast on period rural properties, and K-Rend on newer homes. Lime render is found on the older Georgian and Victorian buildings throughout Winchester city and the surrounding market towns.

Rendered exteriors require the right preparation and the right product for the render type.
Smooth and Fine-Textured Render
Smooth render is the most common exterior finish on post-war housing across Hampshire. It presents well when freshly painted, but over time it fades, stains, and picks up algae. Most rendered properties benefit from repainting every seven to ten years.
The standard process: pressure wash, treat biological growth, fill hairline cracks, prime repaired areas, and apply two coats of breathable masonry paint. On properties where the render was last painted more than a decade ago, a stabilising primer may be needed first.
Colour change is one of the most popular reasons for a render repaint. A house that has been white for twenty years can go to warm stone, soft grey, or charcoal — one of the most effective kerb appeal changes available without building work.
K-Rend and Polymer Render Systems
K-Rend and similar thin-coat polymer render systems are common on properties built or renovated from the 1990s onwards. These systems are typically factory-coloured in the mix and can be painted if the colour has faded or a change is wanted. K-Rend is increasingly common on newer properties in Chandler’s Ford, Harestock, and the Badger Farm developments.
Painting K-Rend requires a compatible masonry paint — not all products adhere reliably to polymer render, and using the wrong product risks early delamination. We use products specified as compatible with through-coloured render systems.
If the K-Rend is structurally sound and simply faded or stained, painting is a cost-effective refresh. If it is cracked, delaminating, or showing substrate moisture, repainting is not the right answer and we will say so.
Lime Render on Period Properties
Older properties in Winchester city centre and in villages such as New Alresford, Twyford, and Kings Worthy carry lime render rather than modern sand-and-cement. Lime render is breathable and flexible by design — it moves gently with the building rather than holding rigid.
Using a non-breathable modern masonry paint on lime render traps moisture in the wall, causing render deterioration and potential internal damp.
We use breathable masonry paints or limewash where the building and its condition call for it. If the property is listed, we advise on whether works require consent before starting.
Biological Growth Treatment
North-facing and shaded render elevations develop green algae and black mould. Painting over contaminated render is one of the most common causes of early paint failure — the growth continues beneath the film and pushes it away from the surface.
North-facing rendered elevations in Kings Worthy and the sheltered village properties around New Alresford develop algae quickly due to prolonged shade.
We apply a mould treatment to affected areas before pressure washing. The treatment kills the growth and lifts it from the surface so it can be removed rather than just covered.
Hairline Cracks and Surface Repairs
Filling Cracks Before Painting
Render develops hairline cracks over time as the surface expands and contracts with temperature changes. These cracks are cosmetic in most cases but will open up further if painted over without filling, and moisture entering through them can cause larger problems.
Before painting, we inspect the full rendered area. We fill hairline cracks with a flexible exterior sealant — one that moves with the render rather than breaking open again. Primed and painted over, these repairs become invisible.
Where cracking is more significant — wider gaps or areas showing movement — we will say so in the quotation. More substantial render repairs are a specialist job and we advise honestly when that is the case.
Preparation Makes the Difference
The difference between a render paint job that holds for a decade and one that starts to fail in two years comes down to preparation. Pressure washing, mould treatment, crack filling, priming, and correct product selection are all required before a topcoat.
Winchester Decorators apply breathable masonry paint by roller and brush, working to a consistent finish across each elevation. On larger properties requiring upper-elevation access, scaffold towers are included in the quote rather than added afterwards.
Here’s How It Works
1. Surface Assessment
We inspect the render condition — cracks, biological growth, previous paint adhesion, moisture staining. K-Rend and lime render are identified and the correct product specified at this stage.
2. Pressure Washing
The full rendered area is washed to remove surface dirt, algae, and loose paint film. Mould treatment is applied where needed.
3. Crack Filling and Repairs
Hairline cracks are filled with flexible exterior filler and allowed to cure. Repaired areas are primed.
4. Masking
Windows, doors, sills, and any brickwork or other non-rendered surfaces are masked before painting begins.
5. Paint Application
A stabilising primer is applied if needed, followed by two coats of breathable masonry paint. Brush and roller are used depending on the texture and scale.
6. Final Check
Edges, reveals, and junctions are inspected. Touch-ups are completed before leaving.

Render Painting Costs in Winchester
Prices below are estimates only. Every property is different. Call 01962 587222 for a precise quote.
Typical Price Ranges
Typical range: £450 to £2,500 depending on property size, render type, and surface condition.
3-bed terraced, rendered front — Chandler’s Ford or Eastleigh: £450–£800. 3-bed semi, all rendered elevations: £900–£1,600. 4-bed detached, fully rendered: £1,400–£2,500. Scaffolding (if required): £300–£600 additional.
What Affects the Cost
Property size and coverage extent — two-storey properties usually require a scaffold tower for the upper elevations, included in the quote rather than added later. Surface condition — heavy algae coverage and significant cracking add preparation time. Render type — properties with lime render or K-Rend may need specialist products at a higher materials cost.
