Excellent service from GNT services (ABJ ) had our indian stone flags cleaned today. They have come up like new. Excellent job and well happy with the result . Excellent professional service from first communication to completed works . Can Highly recommend for any flags or patio cleaning jobs

A great job done by Tony at GNT Services. Very professional and knowledgeable regarding his services and provided this knowledge to help me make a decision. He came and demonstrated the products and his services before the contract to demonstrate what could be achieved. A great service all round from start to finish.

GNT performed an amazing render clean service for Bradford 2025 UK City of Culture in preparation for our first public mural of the BD:Walls project. Highly recommend Tony and the team for similar works in the future.

Scott and Tony from GNT services did a really excellent job cleaning the outside of our house making the rendering look brand new. Wouldn’t hesitate to recommend.

Unbelievable difference after the clean! Would recommend using GNT services (ABJ) for any render cleaning service. The render looks like it’s brand new again, 9 yrs after it was done! So glad to see the original colour back to its former glory. See the before and after shots!! Couldn’t be happier!
