External rendering is applying a protective, weather-resistant coating to the outside walls of a house, using sand and cement, monocouche or thin-coat silicone render, to give a smooth or textured finish that protects the masonry and improves appearance.
For a homeowner in Truro, planning external rendering tends to begin with two questions: what will it cost, and how disruptive will it be? Our guide range is £7,100–£16,500 including VAT, and a typical job runs to 1–3 weeks on site, depending on weather. Both numbers firm up once we have seen the property, measured up and agreed exactly what is included.

How much does external rendering cost in Truro?
No two jobs cost exactly the same, but the ranges below give a fair picture of external rendering in Truro. Pricing for the South West runs about 2% above the national guide, and the overall guide is £7,100–£16,500 with VAT included. We'll confirm your figure after surveying the property for free.

Expect these to shape the final quote:
- Wall area to be rendered and the height of the house
- Render system: sand and cement, monocouche or silicone
- Removing old render or pebbledash and repairing the walls
- Scaffolding, access and protection of neighbouring property
What’s included?
- Survey of walls, existing render, cracks and damp-proof course
- Removal of loose or failed render and pebbledash where needed
- Windows, doors and surfaces masked and protected
- Beads at corners, edges and above the damp-proof course
- Mesh reinforcement and base coats to suit the chosen system
- Making good around pipes, vents and fixings, and a site clean-up
Local housing and external rendering
Older Cornish homes are often built of granite or slatey local stone, with slate roofs and sometimes slate-hung walls facing the weather. Cob cottages survive in places, Truro and Falmouth keep Georgian and Victorian streets, and many towns have rendered post-war houses, bungalows and newer estates on their edges.
Stone and cob properties often need breathable lime render, careful repointing and roof repairs. Post-war and newer homes commonly benefit from new windows, roofline renewal, external rendering and single-storey extensions.
Knowing the typical building types in Cornwall helps, but a survey of your own home in Truro is what decides the right approach to external rendering.
Planning and building rules in Truro
As Truro is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
In England, re-rendering or cladding a house is often allowed without planning permission, but stone, render, timber, plastic or tile cladding is not permitted development in conservation areas, and listed buildings need consent.
If you render or re-clad more than 25% of an external wall, Building Regulations usually require the wall’s insulation to be improved where that is practical, and building control should be notified.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
A visit to your home
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for external rendering so the price reflects your home.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Getting ready
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
Our trades complete external rendering while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

Common questions
Will rendering stop damp?
Render protects walls from driving rain, so it can help where rain penetration is the cause of damp. It will not cure rising damp, condensation or leaks from gutters, and on older solid walls the wrong render can trap moisture and make damp worse. We look for the cause of any damp at the survey and recommend fixing that first.
How much will external rendering cost in Truro?
As a guide, expect to pay £7,100–£16,500 including VAT for external rendering in Truro. That range is adjusted for the South West, which runs about 2% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
Which postcodes in Truro do you cover?
We cover TR1, along with the rest of Cornwall. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
What time of year should rendering be done?
Render needs mild, dry conditions to cure properly, so spring to early autumn is ideal. Most render systems should not be applied when frost is likely, in heavy rain or in strong direct sun, which can dry it too quickly and cause cracking. We plan the programme around the forecast and may pause work if the weather turns, which protects the finish.
How do I look after silicone or monocouche render?
Through-coloured render needs little upkeep. Check it once a year for cracks or damage, especially around windows and pipes, and keep gutters clear so water does not run down the walls. If green algae appears on shaded walls, a specialist render cleaner applied with a soft brush or low-pressure wash removes it. Avoid high-pressure jet washing, which can damage the surface.
