Customer Testimonials

Superb customer service from the Express Toughening team – when I made a mistake on my order online, they dealt with the issue quickly organising partial refund immediately. My order arrived quickly and their courier messaged me before delivery to check I was in. Quality product at the best price I found online.

A massive Thankyou to Helen from Express Toughening for being so patient, co-operative and helpful with my orders. She resolved a re-make without any fuss and in an extremely timely manner. If you want glass – go to Express Toughening and ask for Helen!

Extremely easy company to deal with, glass ordered weeks ago and asked for a specific delivery date due to glass testing and no one being onsite. Delivered on time and when asked for other types glass stated they couldn’t help but recommended an equally helpful company!!

wouldn’t hesitate to use again.

I’ve used Express Toughening twice now and have been very impressed with the glass they have supplied and also the helpfulness of the staff. The first job was a couple of years ago when they supplied me with a 6mm satin frosted toughened glass door for our shower room. From my measurements they supplied a fabulous door which had the hinge and lock holes cut out and also took into account the out of square measurement of the door frame. It fitted a treat and is stunning to look at.

More recently (late last year) they supplied me with painted toughened glass splash backs (7 items altogether in 6mm glass with the biggest being 2.1 metres long), all cut to my sizes and with numerous switch and socket cut-outs. My local glass supplier said they could not cut out the close together sockets and switches, but Express did and got it spot on!

As with the glass door, the splash backs were delivered to me by Expresses’ own transport and without any problems and quality issues.

After the scary bit of fitting them all the result is faultless and stunning. Thanks go to Alex who helped me with the ordering process and technical aspects of glass splash backs.

4mm toughened glass for greenhouse.

Although slightly dubious about ordering from a company I’ve never heard of and not local (300mile away) I’m so glad I took the plunge.

A great customer service from Helen and the team from start to finish, clearly there was nothing for me to worry about.

Their website is easy to use and made ordering online a doddle and for those shapes, they don’t have on their website a quick email and rough diagram sorted any issues there.

All glass arrived on time well packed and with no breakages.

It’s a company I wouldn’t hesitate to use again and I’d definitely recommend it to others who need quality glass cut to size.

Fantastic service, fantastic prices and fantastic products – I could not recommend Express Toughening highly enough – I got an immediate response to my request for a quotation, and Helen was so helpful in answering my questions. Order placement was easy and everything arrived exactly on time and as promised. I won’t look anywhere else for my next order – great prices (way cheaper than other quotes) and great service!

Thank you!
