In short
- Rendering improves kerb appeal, which influences first impressions and marketing photographs.
- External wall insulation can improve a home's EPC rating, increasingly relevant to buyers and landlords.
- Poorly executed render, visible cracks or damp can deter buyers and raise surveyor concerns.
- Keep paperwork: guarantees, building control certificates and any planning consent.
Kerb appeal
A crisp through-coloured render can transform a 1930s semi or 1970s house. Estate agents often cite kerb appeal as significant in attracting viewings.
Energy performance
Where rendering is combined with external wall insulation, the EPC can improve significantly on solid-walled homes.
When render does not help
- Rendering a house in a street where brick is the character.
- Poor workmanship.
- Render that causes damp in period homes.
Protect the value
Keep guarantees, building control certificates and planning decisions. Buyers' solicitors ask for them.
What buyers notice
Buyers form a view from photographs and the first sight of the house. Cracked pebbledash, stained painted render or mismatched patches suggest maintenance is due. A clean, consistent render suggests the opposite. That influences how many people view and how they perceive the rest of the house.
What surveyors notice
A buyer's surveyor will look at the condition of the render and at the details that cause problems: render bridging the damp-proof course, cracks, hollow areas, missing sill drips and signs of damp inside. New render hiding a problem, such as structural cracking covered over, is likely to be spotted and can derail a sale. Render done properly should raise no concern.
Energy performance and lettings
For solid-walled homes, external wall insulation with a render finish can move the EPC rating significantly. The Warm Homes Plan sets an EPC C target for privately rented homes by 1 October 2030, so for landlords the energy improvement can matter as much as appearance. See external wall insulation.
When to hold back
- In streets of consistent, attractive brick, rendering one house can look out of place and planners may object.
- On period homes, the wrong render can harm the building and put off informed buyers.
- If you are selling very soon, a thorough clean and repair can deliver much of the visual benefit at far lower cost. See render cleaning.
Questions people ask
How much value does render add?
There is no reliable figure. Kerb appeal and EPC improvements help; poor work hurts.
Do mortgage lenders mind rendered houses?
Render on a standard brick or block house is normal. Non-standard construction is a separate issue.
Will a surveyor flag new render?
Only if there are problems such as bridging the damp-proof course, cracks or signs of damp. Keep guarantees and certificates to show buyers.
