Your Trusted Glazing Partner

35 Years on the Tools

Grant has been fitting windows, doors and conservatories across Killamarsh and South Yorkshire for over three decades. No sales team, no hard sell just honest work and a fair price, straight from the person doing the job.

Our Story

GTS Glass & Window Services is run by Grant, who’s spent 35 years working hands-on in the glazing trade long before the company existed on paper. That experience is the whole reason customers come back, and why they send their friends and family our way.

We’re based in Killamarsh and cover Sheffield, Rotherham, Chesterfield, Barnsley, Dronfield and Eckington. Every quote, every survey and every installation goes through Grant directly no call centre, no sales rep on commission, just a straight answer from someone who’s done the job thousands of times.

WHY CHOOSE US?

When you get a quote from GTS, you’re talking to Grant not a salesperson working on commission. That means no pressure, no upselling, just an honest recommendation based on what your home actually needs.

We’re FENSA registered and EN1279 certified, so the work meets the standards that matter. And because we’re a small, local operation, every job gets the same level of care Grant would put into fitting his own windows.

I,ve Known Grant many years, hes known in the area as the best in the business when it comes to anything to do with glass, i have started to use him on regular basis for our emergeny glass repairs as no one in the area can touch him on speed or quality.

What can I say , we were burgled and I needed to replace the window asap , called Grant , who was so helpful, sent two lads out to measure up , back the next day to fit the new window, not just glass the full window . All done in less than 24 hrs , I can’t praise GTS enough. Very professional and so helpful, thank you .
