Render Cleaning in Welwyn Garden City
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
We carry out render cleaning across Welwyn Garden City and the surrounding Hertfordshire area throughout the year.
The prevailing picture in Hertfordshire is Victorian and Edwardian housing, garden-city development and extensive modern commuter estates. That means render refresh and colour change on well-maintained commuter housing comes up more here than almost anywhere else.
With a drier inland climate, specification matters more in this part of the country than a national price list suggests. Welwyn and letchworth garden-city stock carries design constraints that affect colour and finish choices more than technical performance.
When render cleaning is the right call. Choose soft-wash cleaning to restore a discoloured render without the substrate damage that pressure washing causes on thin-coat systems.

FAQs
Render Cleaning in Welwyn Garden City
Will cleaning restore the original colour?
On through-coloured render, usually yes — the colour is intact under the growth. On painted render, cleaning may reveal that the paint itself has faded unevenly.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
