About us
Experience in demanding facilities
SIG is a facility cleaning company specialising in high-requirement environments: public institutions, coal mines, universities, transport hubs, swimming pools, production facilities, warehouses and shopping centres.
Over 5 years we have built a portfolio of 40+ regular clients and 50+ documented references across Poland — from Gliwice to Katowice, Kraków, Lublin, Wrocław, Opole and Poznań.
We do not shy away from difficult sites: mine bathhouses, swimming pools, cleanrooms, silos — every contract gets individual treatment.
4 reasons clients come back
We show up when we say we will. Every job is documented with a reference letter.
A dedicated team assigned to each site. No need to re-explain specifics every time.
We work in sensitive environments — courts, mines, warehouses. Full H&S compliance.
No subcontracting. Own certified machinery and chemicals for every surface type.
