About us

CIS have been operating for over 47 years locally and have always been based in and around Bristol.

CIS has been established as a family run business for over 47 years now and boasts a very personal and professional service that we feel others cannot match.

Started by Steve Alger over 47 years ago the company has grown steadily over time to be recognised as one of the most reliable and professional external cleaning contractors around.

Combining two business of CIS Window Cleaning and CIS Gutter Cleaning the company offers a unique combination of both companies with services often overlapping and ensuring clients receive a service that is thorough and effective.

Tom Alger is now the Managing Director and working alongside him Neil Scott as Business Development Director ensures the company runs smoothly and efficiently offering clients a service that is seamless and friendly in its delivery of services.

Considering all aspects of the business Tom has taken and passed his IOSH Managing Safely to oversee and ensure all Health & Safety elements are adhered to – a part of our service we take extremely seriously.

We have a very experienced team of technicians and our lead Senior Lead Technician is Paul Holloway who is responsible for the management of works on site.

Above all CIS is a company that looks to provide that little bit extra and go that extra mile for their clients – friendly and professional to the highest level ensuring you as a client, receive the service you need and expect.

“The results exceeded our expectations and Neil and his crew were a pleasure to work with. Will definitely use them again — though they did such a good job we probably won’t need it done again for quite a while!”
