Professional Cleaning Services in Hertfordshire
Established over a century ago, Gilbros has evolved from its origins as The British Legion Window Cleaning Company into a trusted provider of comprehensive cleaning solutions. Our legacy began by offering employment to ex-servicemen post-World War I, and we have since grown to serve commercial and private clients across Hertfordshire, Cambridgeshire, and Bedfordshire. With a heritage rooted in innovation, we introduced the window cleaning squeegee and now combine traditional ladder methods with modern water-fed pole technology. Our team of CRB-checked professionals utilises state-of-the-art equipment, including 200-bar jet washers and reach-and-wash systems, to deliver exceptional results. We maintain rigorous safety standards, holding Safecontractor accreditation and comprehensive insurance coverage.

Our commitment to quality has earned us long-term partnerships with organisations like the South Essex Partnership NHS Trust. We specialise in window, carpet, office, and specialist cleaning services, including moss treatment and solar panel maintenance. Our 100-year track record demonstrates our ability to adapt while maintaining the highest standards of service. We prioritise punctuality, transparency, and client satisfaction, offering flexible scheduling from daily maintenance to one-off projects. With a direct supervisor contact system and emergency response capability, we ensure reliability for both residential and commercial clients.
