Our window was fitted at the designated time promised by CSJ by two excellent craftsmen who as well as being very efficient with the job , were really pleasant and good natured. When the work was completed they cleaned up and spent time explaining the different locking positions of the window. They also arranged a Plasterer to repair the unavoidable slight damage caused by removing the old woodwork around the previous window. The plasterer also arrived at the arranged time, did a really good and he too was very pleasant. From our experience of the Salesperson, Surveyor, through to the complete installation we would certainly recommend CSJ to anyone.
