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.
We arrange external rendering for homeowners in Gerrards Cross and the wider Buckinghamshire. The job is planned, priced and managed by us and carried out by tradespeople engaged under our contract, so there is one agreement and one contact. On a typical home the work takes 1–3 weeks on site, depending on weather, and guide pricing in the South East is £7,800–£18,000, VAT included.

Homes in Buckinghamshire
Buckinghamshire runs from Chiltern villages of brick and flint, through Metroland interwar semis around Amersham and Chesham, to Victorian terraces in High Wycombe and Aylesbury. Milton Keynes adds estates built from the 1970s onwards in brick, render and timber frame, and new housing continues to spread around its edges.
The Chiltern hills are more exposed than the vale below, and clay-with-flints soils make drainage design and footing depth worth checking early.
That variety is why a guide price for external rendering in Gerrards Cross is only a starting point; the survey shows what your particular property needs.
Planning and building rules in Gerrards Cross
For anyone in Gerrards Cross, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
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.
How does the job run?
Free site survey
First, someone visits your home in Gerrards Cross 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.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for external rendering.
Plan and prepare
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
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
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.
Can you render over pebbledash or old render?
Rendering over existing pebbledash or render is sometimes possible if it is firmly bonded, but if it sounds hollow, is cracked or is coming away, it must be removed first. Covering failing render simply hides the problem until the new coat fails too. We tap-test the walls and explain whether removal is needed. Removal adds time and cost but gives a sound base.
Which render system should I choose?
The right render depends on your walls and how much upkeep you want. Sand and cement is the lowest-cost option but needs repainting every few years. Monocouche is coloured through, so it needs no painting, and suits block and brick walls. Silicone thin-coat is flexible, water-repellent and stays cleaner, but costs more. Lime render suits older solid walls. We recommend a system after inspecting your walls.
How much will external rendering cost in Gerrards Cross?
As a guide, expect to pay £7,800–£18,000 including VAT for external rendering in Gerrards Cross. That range is adjusted for the South East, which runs about 12% 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.
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.
