The whole process was excellent. The sales person talked me through all the options and wasn't pushy. Signing up for the payment option was relatively simple. All workmen turned up when they said they would or even slightly early and the installation was efficient and tidy. I had French Doors installed back in December they are fantastic quality and even after all the bad weather they haven't needed any adjustments. CJS have been fantastic and always kept me up to date with what was happening answered any questions I had promptly and I know even know if I have any problems they are there to help. Highly recommend them they are well worth the investment.
