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 type of house you own in Dartford, we start by looking at how external rendering would fit it rather than offering a standard package. We cover DA1 and neighbouring places such as Bexley, Swanley and Welling. One named person looks after you from survey to handover, and nothing is booked until you hold our figure in writing, fixed for the work described.

Building in Dartford
Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.
Victorian terraces suit loft rooms and rear extensions; weatherboarded and timber-framed buildings may need cladding repairs and lime work. Newer estate homes often take garage conversions, porches and landscaping.
Whatever era your Dartford home dates from, we plan external rendering around how it is actually built rather than a one-size-fits-all specification.
Do you need permission in Dartford?
Because Dartford falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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
We look at the job
A free survey comes first. It gives us what we need to price external rendering properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
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.
Plan and prepare
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
Finish and handover
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
Why homeowners choose us
External rendering in Dartford: questions
How much does it cost to render a house?
Rendering a typical 3-bed semi costs £7,800–£18,000, 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.
Do I need planning permission in Dartford?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Dartford 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.
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.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
