I was very impressed with the service given by Alex and his team at Vale Conservatories. The quote for a replacement conservatory with a warm roof was very competitive and upon acceptance we were given an estimated delivery date which, in these troubled times, seemed reasonable. The work was completed within two weeks and since completion we have been amazed at the difference the warm roof has made. A big thank you to Alex and his team.

Raymond Fountain

Very happy with my new conservatory roof. I had three quotes for the work and was impressed with Alex Fellows' visit, knowledge and sound quotation. I was kept aware of progress at all stages and the work was done on time and budget. I am very pleased with the results.

Hector Pinnington

Vale has just completed the fitting of an Ultraframe replacement (tiled) roof on our conservatory. Every aspect, from initial design to completion of the project, was managed so well in a friendly but highly professional manner. At the start, Alex listened to my concerns about the existing structure and ensured that these were resolved when the replacement was fitted. He also gave very good advice regarding the choice of tiles and the glass roof panels. The whole team were a pleasure to have here, working hard throughout and leaving everything wonderfully clean and tidy. We are delighted with the result and wholeheartedly recommend the company.

Jackie Miller

Alex and his team replaced my old wooden conservatory and transformed the space into a wonderful conservatory room. I was given a very competitive quote for the full build and interior works. The team were very professional. Good quality materials were used and the construction was of a high standard. There were some delays due to the current situation, but it was worth the wait as I'm delighted with the end product. I would definitely recommend Vale to anyone considering any conservatory works.

Christine Baxter

I can highly recommend Vale Conservatories, their service and work was excellent from start to finish. Our large conservatory had a leaking roof and was boiling in the summer and freezing in the winter. We now have a lovely tiled roof, which has been plastered inside and have spotlights for the first time. It now feels like a proper room and will get far more use. It has exceeded our expectations and was far less stressful than imagined. Alex and his team are brilliant and I can't recommend then enough.

Carl White

Fantastic service from Alex and his team from start to finish installing our replacement conservatory windows and roof. Alex pays very close attention to the job throughout and all of his team were exceptionally professional, tidy, friendly and completed their work to a very high standard. Absolutely delighted with the end result and happy to recommend to any potential future customers.

Rob Kent

Vale turned our old, cold conservatory into a wonderful, warm extension that integrates beautifully with the rest of the house now. Alex Fellows was great to deal with - prompt in answering queries or resolving issues, honest and fair in all his dealings. He has an excellent team of workmen who all did highly professional work with a friendly attitude. It is inspirational to see the boss roll up his sleeves and help his team get the work done! Cannot fault this company at all, and would highly recommend them.
