What Our Clients are Saying

We have engaged Peter Cliff of Commercial Ducting & Hood Services Limited to clean the ducting systems at Westfield Queensgate, Lower Hutt since 2007.

During this time he has serviced the ducting systems from the kitchen hoods, through extensive vertical and horizontal ducting to the fan units on either the outside walls or the roof, throughout the mall. These jobs are completed on a six monthly or annual basis.

Our sites incorporate cafes and individual food court outlets, in addition to the main ducting to the mall.

We have been very satisfied with the service and standard of workmanship from Peter and his staff.

If there has been any queries regarding jobs, these have been dealt with quickly and professionally, with a phone call to Peter, or his Area Manager.

Peter's company holds both Telarc and Site Safe Certifications, both of which require a standard of workmanship, and continuous improvement that Commercial Ducting strive to attain at all times.

We look forward to a continued association with Peter and Commercial Ducting in the future.

Yours sincerely

Keith Gordon
