Why Grantham Properties Need Professional Render Cleaning

Grantham’s position in the Witham Valley gives it a slightly damper microclimate than surrounding areas, which combined with its Victorian and Edwardian building stock means biological growth is a persistent problem on roofs, walls, and driveways. Older limestone and ironstone properties in the town centre develop characteristic orange-brown staining from the local stone, while properties closer to the A1 accumulate traffic film and pollution residue at a faster rate than rural Lincolnshire towns.

Is Your Render Letting Your Property Down?

✗

Green Algae Streaks

Green algae streams down from roof edges — creating unsightly streaks on light-coloured render.

✗

Black Algae Patches

Black algae colonises render surfaces in patches that get progressively larger each year.

✗

Lichen Penetration

Lichen attaches to render with root-like structures that penetrate the surface if left untreated.

✗

Pressure Wash Damage Risk

High-pressure washing damages render — the wrong approach strips the surface layer permanently.

Frequently Asked Questions

Q: Do you treat for agricultural dust and debris in the Grantham area?

A: Yes — we use specialist detergent pre-treatments that break down agricultural dust and fertiliser deposits, which require different chemistry than standard traffic film. We've cleaned many properties around Grantham's rural edges with this approach.

Q: Can you damage render with pressure washing?

A: Standard high-pressure washing can strip the surface layer from render. That's why we use soft-wash — the correct approach for all render types.

Q: How long will the render stay clean?

A: With biocide treatment, most renders stay clean for 2–4 years. North-facing or shaded elevations may need treatment more frequently.

Q: Do you clean K-Rend and monocouche render?

A: Yes — we have specific cleaning products and techniques for K-Rend and all modern monocouche render systems.
