Our Story

30 years of experience in the cleaning industry allowed us to differentiate ourselves from other cleaning companies and earn the trust of our clients.


Starting to work in a family business in the cleaning industry can be an exciting and challenging experience. It was an opportunity to learn everything about the cleaning industry from 30 years of experience and start our own company in the sector of housekeeping.

BigMamma began by providing quality cleaning services to households, and soon our reputation for exceptional service earned us the trust of many clients. As our business grew, BigMamma expanded services to include cleaning offices, and before long, private healthcare as well.

The success of BigMamma’s high-quality cleaning services meant that our business was growing at an impressive rate. To better reflect our evolution and the full range of services we offer, BigMamma decided to rebrand and change the name to BigGroup

This new name more accurately reflects our status as a comprehensive facility management company, offering a wide range of services to meet the needs of our clients. With our dedication to providing excellent service and our commitment to continuous improvement –


BigGroup has become a trusted name in the cleaning and facility management industry. 

Our team is committed to providing excellent services to our clients and continuously improving to meet their needs. Good customer service and innovation are crucial for the success of any business, and our team is dedicated to those principles.
