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.
Addresses across CM23 fall within our coverage for external rendering, so if your home is in Bishops Stortford we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £7,400–£17,000 including VAT before that visit.

Local housing and external rendering
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
With that background in mind, here is how we typically handle external rendering for homes in Bishops Stortford, from the first visit to the finished result.
Permissions for external rendering in Bishops Stortford
For anyone in Bishops Stortford, 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?
Survey and measure
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about external rendering.
Price and scope agreed
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Dates and permissions
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.
The work itself
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.
Why homeowners choose us
External rendering in Bishops Stortford: questions
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from external rendering, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
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.
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.
