Very worried about the work currently being done by JWD for Zenith now that I've seen these reviews. As someone else said we didn't know they were contracted to do the installation until they turned up. I was looking for an email contact for JWD to express my concern over the quality of the work thus far. Very messy, no consideration for our home. Damage to plasterwork, poor carpentry on inside window surrounds, damaged cladding on one of our bay windows. Have started work in five different rooms and when leaving today said they will be making a start in two more! That will be three bedrooms with no curtains and mess all over our beds. Luckily haven't paid yet so will be contacting Zenith direct.
