FAQs
Stopcock Replacement in Sevenoaks: FAQs
Do you provide stopcock replacement across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
Why won't my stopcock turn?
This is usually corrosion or scale build-up inside the valve after years of not being used — stopcocks that are never turned tend to seize. We recommend testing yours periodically, and if it won't move, replacing it before you actually need it in an emergency.
How do I know if my ballvalve needs replacing?
Common signs are a cistern or tank that keeps overflowing, runs continuously without settling, or a float that has become waterlogged and sits low. Sometimes an adjustment or new washer is enough, but on an older valve, replacement is usually more reliable.
Does Green Belt designation affect extending a house in Sevenoaks?
Green Belt policy applies primarily to new buildings and significant additions that would be disproportionate to the original dwelling, rather than ruling out modest extensions. We assess this against your specific property and its planning history.
