Graham cleaned our windows and I have never seen them looking so clean.  Not only was the glass sparkling, but the frames were fabulously cleaned!  He did such a good job that we asked him to do our gutters and driveway too.  The neighbours were so impressed that they also have him now cleaning their windows on a monthly basis and their driveway is also looking great thanks to Graham.  Highly recommended. 

We would recommend GSB External Cleaning Services. Had the gutters cleared and then cleaned out and then the windows and frames were cleaned. The work was carried out very efficiently and the white UPVC looked transformed afterwards.

GSB cleaning services transformed our 'green' coservatory from top to bottom, roof, gutters, frames and glass. we would Highly reccommend this company for all your exterior cleaning.
