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.
In Dunbartonshire, we price external rendering against our guide for Scotland, £6,700–£15,500 including VAT, then adjust it once we have surveyed your home. We work across Bearsden, Clydebank, Vale of Leven and Bishopbriggs and the rest of the county or region. Planning and building control requirements follow the rules for Scotland, and we look into your property's position before a written quote is sent.

External rendering prices in Dunbartonshire
What should you budget for external rendering in Dunbartonshire? Use the figures below as a starting point. Prices in Scotland sit about 4% below the national guide, so the range here is £6,700–£15,500 including VAT. Your fixed price comes in writing once we've surveyed the property, at no charge.
| Type of job | What it usually involves | Guide in Dunbartonshire |
|---|---|---|
| Front elevation or small terrace | One elevation or a small terraced house, including scaffolding and preparation. | £2,900–£6,700 |
| Typical semi-detached | All rendered walls of a 3-bed semi in monocouche or silicone, with scaffolding. | £6,700–£15,500 |
| Detached or full strip and re-render | Larger houses, or homes needing old render removed and walls repaired first. | £14,500–£29,000 |
The main things that change the figure:
- 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?
- Scaffolding erected and removed, with neighbours' access agreed
- 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
Homes in Dunbartonshire
Clydebank was heavily rebuilt after wartime bombing and has tenements and post-war estates, while Dumbarton has sandstone tenements and Victorian housing. Bearsden and Milngavie are known for Victorian villas and interwar bungalows, and Kirkintilloch mixes older terraces with post-war semis and newer developments.
Bungalows commonly suit loft conversions with dormers, and villas often take kitchen extensions and landscaping. Tenement flats may need window replacement, and harled homes often need re-rendering.
The west of Scotland gets frequent heavy rain and wind, so driving-rain exposure is a key consideration for render and pointing.
Planning and building rules in Dunbartonshire
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Dunbartonshire comes under Scotland, covered below, and we raise any questions with the council before your quote is finalised.
In Scotland, changing the external finish of a house in a conservation area or on a listed building needs consent; elsewhere, like-for-like re-rendering is usually treated as repair.
Large-scale re-cladding or external insulation can need a building warrant; like-for-like render repairs normally do not.
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
We look at the job
First, someone visits your home in Dunbartonshire to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Your fixed price
After the survey we send a quote for external rendering that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Getting ready
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
The work itself
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
What you can expect from us
Questions about external rendering in Dunbartonshire
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.
How much does it cost to render a house?
Rendering a typical 3-bed semi costs £6,700–£15,500, including scaffolding and preparation. As a guide, allow around £60–£120 per square metre of wall plus fixed costs for scaffolding and set-up. Sand and cement is the lowest-cost system, while silicone thin-coat costs more but needs no painting. Removing old render or pebbledash first adds noticeably to the price. We confirm a fixed figure after the survey.
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 long will external rendering take?
On a typical home, allow 1–3 weeks on site, depending on weather. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Do you cover Bearsden, Clydebank and Vale of Leven?
Yes. As well as Dunbartonshire, we cover Bearsden, Clydebank and Vale of Leven and the rest of Dunbartonshire. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
