About us

We were founded by Gary Sanderson in 2010. Gary had over 30 years’ experience in the door business and his expertise and dedication to providing exceptional service laid the foundation for GLS.

Although he sadly passed away in 2020, his unwavering commitment to clients and his passion for delivering top-quality service has allowed GLS to continue.

Today, GLS is led by Gary’s close family and colleagues, who worked alongside him for over 30 years. They continue to uphold the same client-focused values that originally shaped the business.

Our Vision

We specialise in the installation of a wide range of electrical and industrial doors, including roller shutters and barriers. We have vast amounts of experience working with several different companies, including household brands, local councils and international businesses.

Our main office is strategically based near the M25, making us easy reach from London and the Home counties.
