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.
Whatever prompted you to look into external rendering, whether wear and tear, a growing family or plans to move, we can survey your Farnham home and give you a price in writing. Homes in the South East typically come in at £7,800–£18,000, VAT included, for this kind of work. We also cover Aldershot, Fleet and Farnborough, and the same steps apply wherever you are in Surrey.

How much does external rendering cost in Farnham?
No two jobs cost exactly the same, but the ranges below give a fair picture of external rendering in Farnham. Pricing for the South East runs about 12% above the national guide, and the overall guide is £7,800–£18,000 with VAT included. We'll confirm your figure after surveying the property for free.
| Type of job | What it usually involves | Guide in Farnham |
|---|---|---|
| Front elevation or small terrace | One elevation or a small terraced house, including scaffolding and preparation. | £3,400–£7,800 |
| Typical semi-detached | All rendered walls of a 3-bed semi in monocouche or silicone, with scaffolding. | £7,800–£18,000 |
| Detached or full strip and re-render | Larger houses, or homes needing old render removed and walls repaired first. | £17,000–£33,500 |
Your price depends mostly on:
- Wall area to be rendered and the height of the house
- Removing old render or pebbledash and repairing the walls
- Scaffolding, access and protection of neighbouring property
- Detailing around windows, bays, sills and pipes
Scope of the work
- Survey of walls, existing render, cracks and damp-proof course
- Removal of loose or failed render and pebbledash where needed
- Beads at corners, edges and above the damp-proof course
- Mesh reinforcement and base coats to suit the chosen system
- Finish coat in your chosen colour and texture
- Making good around pipes, vents and fixings, and a site clean-up
What are homes like around Farnham?
Surrey has many Victorian and Edwardian villas, interwar semis in the commuter towns near London, and Arts and Crafts houses with tile-hanging and tall chimneys. Bargate stone appears around Godalming, and large detached homes are common in Guildford, Woking, Weybridge and the Surrey Hills villages.
Larger homes often take kitchen extensions, bifold doors, landscaping and driveway renewal. Interwar semis suit loft and side extensions, while tile-hung and period properties may need roof and hanging-tile repairs.
Whatever era your Farnham home dates from, we plan external rendering around how it is actually built rather than a one-size-fits-all specification.
Permissions for external rendering in Farnham
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Farnham comes under England, covered below, and we raise any questions with the council before your quote is finalised.
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.
From survey to handover
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.
Quote in writing
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.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
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.
What you can expect from us
Frequently asked questions
Can you combine external rendering with other work?
Yes. Because we manage several trades under one contract, we can plan external rendering alongside other work on your Farnham home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
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.
Do I need planning permission in Farnham?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Farnham is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
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.
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.
