Rated 5 out of 5 stars

Absolutely top-notch from start to finish.

We changed all the windows in our house through TVWC. We first spoke to Rob, who was very knowledgeable, gave us a great price and no hard sell. Before signing we visited the showroom, made a few alterations to our plans and there was still no pressure to sign (unlike other companies we were considering).

The fitting went quickly, with a professional and friendly crew who did a fantastic job. The final result exceeded our expectations and has made a huge difference to the exterior of our house.

I cannot recommend TVWC highly enough. If you're looking for replacement windows then these are the guys to use!

Very happy customer

The whole process was easy. They kept me informed on progress and at what stage they were at. To be honest I was surprised how quick it was. Fitters did a great job too. Very happy. And it looks very nice!

Gorgeous windows and front door

George was amazingly patient whilst we developed our ideas and was always on hand to answer questions and give advice.
Our windows and front door are now installed and look amazing -they are sturdy and finished beautifully. They have completely transformed the house. I LOVE them!

Out of warranty issues

Out of warranty I've found that the orangery main pillars are rotten behind the paint. Goodness know how I'm going to repair these.

Hi Colin, as per our telephone conversation, although the Organgery is out of warranty, as a gesture of goodwill, our site manager, Jon, will visit on Monday, 16th June, to audit the pillars.

Great team, lovely product

We worked with 4 people from Thames Valley on our project for bespoke windows, from design through to installation. Everyone was responsive, knowledgeable and helpful at each stage. Couldn’t be happier with the finished product and the customer service.

Excellent job

Sean went the extra mile to make sure we got the result we wanted. After the first batch of windows was installed last year so well by the fitters we decided to have another set done and the result was equally good. Thanks to all at TVW for a very professional job.

Excellent Service and Workmanship

We have used Thames Valley Windows for all our needs over the last 28 years. We did look at a few companies this time but were not even happy with their responses on enquiry. TVW from Salesman, through communication with the office, to the excellent installation team were just as good as all the other times we had employed their services.
Special thanks to Rob, Suzy, Matty, Sid and Carl for the very smooth operation from initial enquiry to finished installation of our quality windows and doors.
I would definitely recommend TVW.

"OUTSTANDING QUALITY PRODUCTS AT A COMPETITIVE PRICE"

We contacted 5 window companies in order to get quotes to replace double glazed wooden sash windows & TVW were not only the most competitive price wise but also the service was impeccable. From meeting the sales consultant Rob Legge through to the surveyor & installation team the service & products were exceptional. We would not hesitate to recommend the company.

Great service!

Sean, our design consultant listened attentively to what we were looking for and was able to give us honest, clear advice and guidance, to enable us to make an informed decision that met our needs. We didn't feel rushed and he only left once he had our requirements clearly outlined and our questions answered.
The fitting went smoothly, on the expected date and we are delighted with the final product. Thank you!

New windows

Had new windows fitted today. The fitters turned up on time, were polite, friendly and helpful. The windows were fitted in a prompt, efficient manner and look great.
I enjoyed the whole process of working with Thames Valley Windows. All of the staff we met came across as very experienced and knowledgeable, which was very reassuring. They went out of their way to provide invaluable advice, not only regarding practical matters but also aesthetically.
It was basically a three stage process: 1. Initial visit by designer. 2. Visit by surveyor a couple of weeks later.
3. Fitting about a month later.

I highly recommend this company. Highly professional, reliable, honest and friendly.

Great windows, great service

On the basis that you get a much better view of a company's values and behaviour when things don't go perfectly, I have to give full marks to Thames Valley Windows. When there was a problem with the instal they understood the situation, immediately accepted that there was an issue, responded very quickly and made a complete commitment to resolving it.
My installation was quite complex and the issue wasn't particularly major (misalignment of leading) but I was very impressed by their response and that they made a big effort to fix the problem to my complete satisfaction.
This is how a 'proper' company behaves and I would strongly recommend them on that basis alone.
However, the windows are great and, even including the problems encountered, the whole experience was very positive.

Won't be using again

Unfortunately, we didn't have the best overall experience with TVW. When the doors arrived to be installed, they were made the wrong way round, the master door being on the wrong side. So we had to wait for the doors to be sent back to the manufacturer and swapped around.
When the doors finally arrived back and were installed, we had to call the manager out to inspect scratches and marks- quality we absolutely would not expect. He then told us that gaskets had not been installed in some areas, so we would have to get someone back out to fix those. When that was done, we noticed even more scratches!!
TVW got specialist sprayers out to fix all the scratches and marks and finally we have been left with doors we are happy with. But the whole process was very stressful and not what we would have expected at all.
They were very apologetic and professional about everything. We hope this is a one off and just an unfortunate run of events, but for the price we paid, it was not the standard of service we would expect and we won't be using this company again.

Dear Phillippa

Thank you for taking the time to review Thames Valley Windows and your feedback.

Again, we apologise for the disappointment caused and the time taken to get the right end result. Our commitment to achieving a level you are happy with shows our standards as a business and our dedication to your satisfaction.

We wish you the best for the future and hope you can now enjoy the doors as they should be.

Excellent all round service

Excellent service throughout the process from George in sales, admin, survey to the install guys. Having had a previous poor experience with another window company it made a refreshing change! Would definitely use again.
