NEW! The Borough Wharf Doorstep Vent Guard is the latest pest-proofing solution developed by Borough Wharf. The name says it all. Stop pests entering your property through doorstep vents. Doorstep vents are common with Victorian homes, and like most imperial properties, inconsistencies are also common. Not all doorstep vents are the same size. A key feature of the Borough Wharf Doorstep Vent Guard is the ability to easily cut the Doorstep Vent Guard to the desired size to get that snug fit. No need for construction adhesive or screws for installation, as the Doorstep Vent Guard comes with high performance bonding tape already attached to the back of the frame. The frame is made from Fire Retardant PVC and the 3mm stainless steel woven mesh helps guard against other unwanted pests such as wasps, slugs and cockroaches, with absolutely no interruption to air flow.
