What our customers are saying

  • Your fitters Toby and David fitted new patio doors and two exterior doors for us on Monday 2nd October and what pleasant and efficient people they were too. We were highly surprised yesterday to be contacted by Toby who said that he had realised that they had not fitted some plastic caps(?) to the exterior doors - which we were completely unaware of - and could he come along and fit them. We of course agreed and within half an hour he arrived and fitted them. Now I call this customer service of the very highest degree. Most impressed. Would you please thank Toby and David. I also demand(!) that you pass on this message to their manager and to the Managing Director of your business. Thanks

  • I wish to say thank you for the efficient and timely way in which your two Engineers repaired the runner on our patio door this morning. They arrived on time, used a ground sheet to take care of the carpet and did a good job Thank you

    Mr & Mrs B – Cheltenham
  • I would like to thank you for your help getting planning permission for my windows. It wasn’t the easiest thing in the world but you managed it. The crew who fitted my windows were helpful, polite, cheerful and cleaned up after themselves every day. I couldn’t have asked for a better team. The windows have transformed the house. I love the sashes but also the simpler ones on the back windows look lovely too.

  • Thank you very much for the most impressive response to our broken window catch. Engineer fixed same day we rang you. Very impressed with your excellent service.

    Mr L – Malvern
  • Just wanted to say thanks for the speedy response to the roof problem on my 23 yo conservatory which I called about yesterday afternoon. Your guy did a great job this morning and I now feel we have a secure set of roof panels. A great service after all these years. Thanks again.

    Mr H – South Gloucestershire
  • Thanks again for all of your (and Alan's) help - it really has transformed our house and the whole experience of dealing with High Tech (as a customer this time!) has been excellent.

    Mr T - Gloucestershire
  • Sincerest thanks for the cheque for £50 sent to me on 30 March relating to me recommending you to Mr & Mrs E.  Very happy to help; my wife and I remain delighted with our High Tech products and installation, and it has been a very easy task to recommend you to many other friends and neighbours.

    Mr H - Gloucestershire
  • I would just like to say how pleased I am with your exceptional product support and the professionalism of your staff. I had a small problem with a window that had been fitted fitted five years ago and this was fixed without any fuss within a few hours of my call to the Office. I don't normally provide feedback to companies but just felt I had to let you know how pleased I was with your service . Many Thanks, Peter

    Mr B – Gloucester
  • I have recently had a repair to the conservatory which I purchased from your company 12/13 years ago.  Duncan March (Service Engineer) came along and assessed the situation and after a few weeks came to Winterbourne and affected a repair.  Since then it has had a real test with the heavy rainstorms, and the conservatory was totally dry.  I am so pleased with the efficient way your staff dealt with the situation and delighted when I was told there would be no charge especially with the guarantee no longer in operation.  The Goodwill that goes along with such a gesture is tremendous

    Mrs K – Winterbourne
  • I had High-Tech windows and doors fitted throughout our property and at the time, after installation, I felt I had to write to you to say what a fantastic job your team of fitters had carried out.  Well, it’s happened again!!!!  I had an alignment problem with our patio doors and the locking mechanism was causing problems.  I hardly had time to put the phone down before your technician had arrived and very professionally fixed the fault…  What a fantastic service and company High-Tech is.

    Mr A – Cheltenham
  • Your installation of our windows was superb at every stage from sale to survey, through to installation.  Keep up the good work.

    Mr and Mrs B – Tewkesbury
  • At all times the fitters were polite, clean, tidy and informative and let me know at every stage of the work what they were doing and why.  It was a pleasure to have them in my home.

    Mrs W – Tuffley
  • I am completely delighted with the quality of the units and workmanship

    Mrs W – Tuffley
  • It was the second time we’ve used High Tech and we would certainly use you again.  We’ve found you very professional and reliable.

    Mr and Mrs R – Gotherington
