Double glazing
Customer Service
We contacted Test Valley for a quote to replace our double glazing throughout the house. Their communication was comprehensive and very thorough and their quote was very competitive. We put the work out to tender to five different companies and Test Valley windows were by far the best in every aspect. The work was carried out a week ahead of schedule. The installers were with us for five days, they worked very well as a team and were extremely efficient. At the end of each day they tidied up after themselves left the house spotless. In the light of our experience we would have no hesitation in recommending them.

Conservatory work
Customer Service
Teat Valley Windows put up a brand new conservatory for me. The work was done very meticulously and they were very professional throughout. I wish we had done this sooner - the work is so good we have an extra room throughout the year now. I would recommend Malcolm and his team to anyone looking for windows, conservatories and a whole lot more I am sure. This is the second conservatory Test Valley Windows have built for me (two different houses!). I don't intend on having a third but they will be first on my list when the windows need doing. Well done team - excellent work.

Impressive After-Sales Support!
Customer Service
Test Valley Windows have been an incredible company to deal with. They supplied and fitted new front and utility room doors four years ago, complete with a 10 year guarantee. When the doors started to fade, we got in touch with the Test Valley Windows team, and were so impressed by their professional and helpful response. They offered to replace the door slabs, without quibble or hesitation. Arranging an appointment for the door engineers to come was quick and easy. The two-man team worked solidly for hours, getting the door hanging just right. They clearly took huge pride in their work and did an amazing job even removing and refitting a blind on one of the doors...they went above and beyond and we are delighted with the replacement products. All a customer, I feel valued and appreciated. The entire experience was positive...thanks and well done Test Valley Windows!

Great service
Customer Service
We bought our front and back doors from Test Valley Windows. We were impressed with the professional service received throughout the process, from the showroom, to the door fittings, to the customer service received afterwards when we needed some minor adjustments made. All services were very prompt and the staff friendly and courteous, and we are very pleased with the finished product. Special mention goes to Dave who never failed to deliver service with a smile despite having to wait outside our house for a long time as we were in the back garden and couldn't hear him! We're really pleased with the doors, they look beautiful on our house.

Prompt and professional
Customer Service
They worked well and the job went according to plan. One problem they quickly remedied and this did not affect us. We only had their quote for value and this was within the region we thought so we have awarded a 5 score.

Very professional & highly recommended
Customer Service
Using Test Valley was a great experience from start to finish! Nigel was very helpful when it came to explaining the options and price, Malcolm did a great job of making sure everything was planned and organised before the installation and the team on the day did a fantastic job and cleaned everything up each day to the extent you wouldn't have known they had been there.

New French windows and back door
Customer Service
We had several different quotes but test valley was not pushy like the others as they literally explained what we could have for our money. Overall they were very ease to deal with - on time and no mess left at all. Great after care - the office kept us informed very well
