No thank you

Tried to order some replacement double glazed units and found the experience quite odd.
The person dealing with my request didn't appear to be very knowledgeable. Contacted me
once and I haven't heard from them since, that's a week ago.
I have since been fixed up by a company who are completing my order in the next few days.

Glass Splashbacks

We purchased a new kitchen (summer 2017) and selected Treforest Glass to manufacture and install the glass splashbacks, in total being 3 pieces with 6 cutouts across more than 5 metres. From the initial telephone enquiry through the measuring, quotation, templating, manufacture, delivery and installation the service we received from all departments was excellent.

Particular mention of Cathy who talked us through all the available options, ordering and payment, plus Paul and Keiron who did the accurate measuring and fitting. They were both very easy to have in our kitchen for 2 hours, being polite and thoughtful to our needs and exceedingly tidy and clean, making this a superb, quality job.

We are very, very pleased with the glass splashbacks and have no hesitation in recommending Treforest Glass for this type of work.
