Algimouss

What Algimouss does

Algimouss is a French manufacturer of professional chemical products dedicated to cleaning, treating and protecting building exterior surfaces, including roofs, façades, terraces, exterior floors and indoor walls. Founded in 1978 (operating since 1976) and headquartered in La Séguinière (Maine-et-Loire, France), the company invented the first anti-green-deposit treatment and has built a 100-product portfolio organised into three ranges — cleaning, treatment and protection — covering roofs, walls and outdoor floors, plus a parallel eco-responsible sub-brand called Algi-Vert that uses a biocide-free probiotic formulation. Underlying technology centres on water-based biocide chemistry combining algicides, fungicides and surfactants in synergistic molecule blends, supplemented by the proprietary Algi-Vert probiotic approach and a line of Algipulvé branded sprayers and telescopic lances.

The company sells exclusively through indirect channels: a network of 3,200 distributors across France and Europe and a separate network of approved applicators who are trained and authorised to apply the products professionally. Revenue mechanics are one-time product sales across packaging formats from 1L to 30L, with no recurring contract model and no public pricing; the B2B professional applicator segment is the primary customer, with a secondary B2C homeowner segment served through the same distributor footprint. The company holds EcoVadis Bronze (2025) and EXCELL ZONE VERTE / EXCELL+ certifications, manufactures 90% of its products in France with 90% French suppliers, and operates from a headquarters that also houses production.

On June 30, 2025, Algimouss was acquired by PRB, a Vendée-based company that is itself a subsidiary of the Holcim Group, ending nearly five decades of independent operation and embedding Algimouss inside a global building-materials conglomerate. The company employs 33 people and is preparing for the January 1, 2026 Certibiocide regulation that will govern the sale and application of its biocidal SKUs in France.
