Conserv-a-Tech offered us a very professional and friendly approach right from our initial enquiry, providing us with some new ideas for our refurbishment plans to update our very dated conservatory. The whole team were all very polite and worked with confidence throughout the whole project. Keeping the work area tidy and they also cleared up at the end of each days work. Our refurbishment also included the need for an electrician and a plasterer who both provided a high class installations and finish. I would highly recommend this company to anyone

Great team to work with - from design to installation everyone was really friendly and courteous. Good workmanship, hard working, patient, reliable and attentive, taking any issues of mine on board as we went through project. I've had loads of work done on the house over the last ten years and this was by far the best team I have dealt with. Very reliable. How often can you say that? Obviously for a project of this size there were some issues as we went along but they were all dealt with without any significant hassle or inconvenience. Delighted with finished product. Thoroughly recommended.

After using Conservatech for our new windows and doors last year and being so impressed with them there was only one company we wanted to use for our garage conversion. Eric the owner had some excellent ideas on how we could convert the garage into two rooms and knock through into our living room. Again the quality of workmanship was excellent and the finished project looks amazing. Eric handled all building regulations and we had certification provided within a couple of weeks of the project finishing.
