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.
Holyhead sits within our coverage for external rendering, as do neighbouring Caernarfon, Bangor, Gwynedd and Llandudno. Before giving a price we want to see the property: the condition of what's there now, the access, and anything that might need extra work. The guide range for Wales is £6,400–£14,500 including VAT, and your written quote will spell out exactly what that covers.

How much does external rendering cost in Holyhead?
No two jobs cost exactly the same, but the ranges below give a fair picture of external rendering in Holyhead. Pricing for Wales runs about 8% below the national guide, and the overall guide is £6,400–£14,500 with VAT included. We'll confirm your figure after surveying the property for free.
| Type of job | What it usually involves | Guide in Holyhead |
|---|---|---|

| Typical semi-detached | All rendered walls of a 3-bed semi in monocouche or silicone, with scaffolding. | £6,400–£14,500 |
| Detached or full strip and re-render | Larger houses, or homes needing old render removed and walls repaired first. | £14,000–£27,500 |
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
- Detailing around windows, bays, sills and pipes
What’s included?
- Survey of walls, existing render, cracks and damp-proof course
- Scaffolding erected and removed, with neighbours' access agreed
- 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
Homes in Gwynedd
Slate defines much of Gwynedd, from quarrying villages such as Bethesda and Blaenau Ffestiniog with their stone terraces to slate roofs across the county. Bangor and Caernarfon have Victorian and Georgian streets, Anglesey has stone cottages and bungalows, and resorts such as Pwllheli and Barmouth have Victorian terraces and newer bungalows.
Stone and slate homes need breathable lime render and pointing, and slate roofs often need careful repair rather than replacement. Terraces suit loft conversions, and bungalows commonly take extensions and window upgrades.
Building traditions across Gwynedd also raise conservation and planning questions, so we check those for external rendering in Holyhead at the survey stage.
Do you need permission in Holyhead?
The notes below cover Wales, which is where Holyhead sits. Rules change and every property is different, so we speak to the council before pricing your job.
In Wales, rendering or cladding may need planning permission in conservation areas, and listed buildings need consent.
Building Regulations in Wales can require insulation upgrades when a large part of an external wall is renovated.
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
Free site survey
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Price and scope agreed
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
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.
Build and hand over
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Frequently asked questions
Do you cover Caernarfon, Bangor, Gwynedd and Llandudno?
Yes. As well as Holyhead, we cover Caernarfon, Bangor, Gwynedd and Llandudno and the rest of Gwynedd. 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.
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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
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 much does it cost to render a house?
Rendering a typical 3-bed semi costs £6,400–£14,500, 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.
