Specialist Exterior Care

Professional Render Cleaning in Renfrewshire & Glasgow

Render can lose its fresh appearance as algae, lichen and other organic growth leave green, red or dark marks across the walls. Our render cleaning service treats this build-up using a low-pressure approach, selected around the finish and its condition rather than relying on a powerful jet of water.

We assess K-Rend, silicone, acrylic and cementitious render, along with roughcast and painted masonry, before choosing appropriate cleaning products and biocides. The aim is to tackle the growth behind the staining while caring for the existing finish. Some treatments continue working after application, so we explain what changes to expect as the surface responds.

Whether it is one stained wall or the exterior of a home or commercial building, we consider access, nearby planting and the surrounding surfaces before work begins. Cleaning does not repair cracks or failed render; we will explain the proposed cleaning method and provide a free, no-obligation quote for the areas you would like treated.

We have used Nutech Cleaning on a couple of different properties and every time they have done an amazing job with the driveway, roof and gutters. They are really friendly and knowledgable and super efficient. We can't recommend them enough.

Great service from a professional team. They took great care in cleaning gutters, washing them and fascia then jet cleaning driveway and re-sanding it. A very fair price for work that was carried out promptly. If you live in West Dunbartonshire area don't be put off as firm based out with area in Bishopton . Thank you for the service.

FAQs

Render Cleaning Questions

How do you clean render?

We select low-pressure products and biocides around the finish, condition and organic staining.

K-Rend, silicone, acrylic, cementitious and monocouche render, along with roughcast, pebbledash and painted masonry.

Low-pressure treatment avoids forcing water into the render and lets the cleaning product tackle the organic staining.

Yes. Biocide treatments continue working after application, helping address organic growth rather than simply rinsing the surface.

Yes. Roughcast and pebbledash are among the surfaces assessed for low-pressure treatment.

No. It uses low-pressure application of specialist products rather than forceful water on delicate surfaces.

No. Cleaning treats organic staining, not cracks or failed finishes.

The growth and treatment affect the response. Biocides can continue working after application.

We assess the surroundings when selecting treatments. Tell us about planting and sensitive areas before work.

Location, render type if known, photos of staining and access information are helpful.
