A company like JSS is only as good as the trades men got working for them , & the trades men who worked on our conservatory who was Simon the joiner & Martin the bricklayer who did all the work with a couple of apprentices & the project turned out excellent also we had no trouble on the administration side of the company . I was in the building trade for over 40 yrs so I would give this company 5 star rating .

I have had some windows and a door replaced and everything was done efficiently and to a high standard. Jarrad was the fitter and he was great, making sure i was happy with everything throughout and even though there were some unforseen structural issues with my house they were able to get a bricklayer to come out and it was all handled very quickly and the window instalation went ahead as planned. Great service would recommend them.

There was a mix up with my order however the company offered a solution which I was happy with. I now have my new door and all is well. The fitter was a polite young man and did a professional job and left everything clean and tidy. I would certainly use JSS Installations again. Service: General door installation

We ordered a new bathroom window and tilt and turn patio doors, we were delighted when J.S.S contacted us well before the given installation date to ask if we would have the work done earlier. The window installer Jarrad arrived at the time arranged and given that he was working alone got the job completed at the time he estimated. The installation was completed without hitch and was very well done. Jarrad kept us informed of all aspects of the job and for our choice of trim and colours where needed. All the work was excellently done and the windows and doors of good quality. All in all a very good and at a very good price.
