FAQs
Steel Installation in Sevenoaks: FAQs
Do you provide steel installation across all of Sevenoaks?
Yes, we cover the TN13 postcode area in full, including Riverhead, Dunton Green, Weald, Bat & Ball, Kippington.
How is a steel beam sized for my opening?
A structural engineer calculates the required beam size and type based on the span of the opening and the load it needs to carry — including the floor or roof structure above and any additional loads such as water tanks. This is confirmed before ordering the steel.
Can a steel beam be installed without removing the whole wall?
Often yes — a beam can be installed to widen an existing opening or doorway rather than removing an entire wall, with the remaining sections of wall providing the bearing for the steel.
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.
