Render Cleaning in Bangor
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Our render cleaning work in Bangor starts with a free survey, because guessing at a render specification is how jobs go wrong.
Gwynedd is characterised by slate and stone cottages, quarry housing and exposed coastal properties, with extreme driving rain on slate and stone construction the recurring theme on the properties we survey.
Bangor sits in a part of the UK that gets among the highest rainfall in the UK with severe exposure — worth factoring into any render decision. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
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 Bangor
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.
