A cleaner finish. A considered approach.
Discolouration can make an otherwise well-kept property look neglected. Green growth and dark marks often build up where exterior walls stay damp, especially on shaded elevations or around overflowing gutters.
Cleaning may improve the finish without the cost and disruption of repainting or replacing sound render. The first step is identifying what is causing the staining and checking the condition of the surface beneath it.
GNT Services provides domestic render cleaning and commercial render cleaning, with a local base in Oakworth that puts us close to properties throughout Keighley.

Three examples of GNT Services’ render cleaning work. Each pair shows the same property before and after treatment.
Results depend on the render’s condition and the type of staining.
The right method for your walls
Render is not a surface to approach with indiscriminate high pressure. Its age, finish and condition affect which cleaning method is appropriate. We check for loose material, cracks and vulnerable areas before deciding how to proceed.
Where suitable, soft washing uses a controlled treatment to tackle organic growth, with gentle cleaning or rinsing as required. The aim is to address the source of biological staining as well as improve the appearance of the wall.
Tell us if your property has K-rend, monocouche, silicone render or painted render. If you are unsure, send photographs. We can discuss suitability and whether a closer inspection or test area is needed.
Simple from the first message
Include a full view of each elevation, close-ups of the staining and any access restrictions. Use WhatsApp, email, the enquiry form or call to discuss the work.
We discuss the likely treatment, access and what can realistically be achieved. Some properties need a visit before we can confirm the scope and price.
Once the work is agreed, we arrange the clean and explain any preparation needed. Timing depends on access, weather and the treatment selected.
Oakworth based. Keighley covered.
Our base is in Oakworth, near Keighley. We welcome enquiries from homeowners, landlords, managing agents and businesses across the town and neighbouring villages.
From a single stained elevation to a larger rendered building, send us the location and photographs so we can discuss the work and practical access requirements.
Where leaking gutters, poor drainage or damaged render contribute to staining, cleaning alone will not resolve the underlying issue. We explain what the clean can achieve and flag problems that may need attention first.
Need other exterior surfaces cleaned at the same property? Mention them when you enquire. We also provide driveway and patio cleaning and gutter cleaning.
Before you book
The price depends on the area of render, the level of staining, the height of the building and access. A small, accessible wall is a different job from several elevations needing specialist access. Send photos and your postcode so we can assess what is involved and explain the next step.
If the render or coating is sound and the main problem is organic staining or surface dirt, cleaning may be enough to improve its appearance. Faded paint, cracks and failing finishes may still need repair or decoration. We assess the surface before recommending a clean.
Unsuitable pressure or technique can damage vulnerable render and force water into defects. We select the approach around the material and its condition. Soft washing and controlled rinsing may be appropriate, but suitability needs checking for each property.
These surfaces can often be cleaned, but the finish, age, staining and manufacturer’s guidance matter. Tell us what type of render you have, if known, and provide photographs. We will discuss a suitable approach and any need for a test area.
There is no single timescale. Shade, vegetation, damp conditions and the condition of gutters all affect how quickly growth returns. Treatment may help slow regrowth, but it does not make a wall permanently resistant to algae.
Yes. We welcome enquiries for homes and commercial rendered buildings in and around Keighley. For larger properties, include details of the building’s use, height and access restrictions so we can discuss the assessment and planning required.
Choose WhatsApp, phone, email or our online enquiry form. Include your postcode and details of the walls you want cleaned. Photographs help us understand the staining, access and surface condition before discussing the next step.
