Practical points for boundary work in East Barnet
Digging in waterlogged winter ground
A post hole dug in saturated winter ground can collapse in on itself before concrete goes in, particularly in sandy or silty soils that don't hold a vertical face when wet.
Digging a slightly wider hole and using a temporary former — a section of pipe or shuttering — to hold the sides while concrete is placed can rescue a hole that would otherwise keep sloughing back in.
Where conditions are bad enough that holes won't stay open at all, it's often more efficient to wait for a drier spell than to keep re-digging the same collapsing hole through a single working day.
Handling excavated spoil on a fencing job
Digging even a modest run of post holes generates a surprising volume of spoil, and leaving it in a single heap on a lawn for the duration of a job kills the grass underneath if left more than a few days.
Spreading spoil thinly on a border, bagging it for removal, or arranging same-day disposal all avoid that dead patch, and the right choice depends on whether the client wants the spoil kept for landscaping elsewhere on the plot.
Heavy clay spoil is particularly slow to dry and awkward to barrow once it's rained on, so timing the dig to avoid leaving wet spoil sitting overnight where possible reduces both the mess and the extra effort of moving it later.
Places of worship
Boundary fencing around a church, mosque, synagogue or other place of worship often needs to work around a burial ground, memorial garden or community hall use that changes access patterns through the week rather than a simple daily schedule.
Many places of worship are listed buildings or sit within a conservation area, which brings the same consent considerations as a listed private house to any boundary wall or railing repair.
Because these sites often host services or events with unpredictable footfall, agreeing working hours and access routes with whoever manages the building in advance avoids clashing with a ceremony or gathering.
Protecting a patio surface during fencing work
Dragging posts, panels or a wheelbarrow across paving can chip edges or scratch a polished or textured finish, so boards or protective sheeting laid along the route reduce that risk on a patio the client wants kept intact.
Concrete spillage from mixing or haunching is another common cause of permanent staining on natural stone or porous paving, and it sets far harder to remove than it is to prevent with a simple dust sheet under the mixing point.
Where post holes have to be dug close to a patio edge, protecting the adjoining slabs from spoil and tool marks is worth doing before digging starts rather than cleaning up afterwards.
RAL colours and UV fade
RAL is a standardised colour matching system widely used for powder coating and factory paint finishes on metal fencing and gates, allowing a specific shade to be reordered consistently years apart.
Darker RAL shades, particularly reds and some greens, tend to fade faster under UV exposure than blacks and greys, since the pigments used to achieve those colours are often less UV-stable.
South-facing runs in direct sun for most of the day will fade noticeably faster than a shaded run of the same colour and coating, which is worth factoring in in when matching an extension to existing fencing.
Powder coating and galvanising
Galvanising bonds a zinc coating to steel, usually by hot-dip, giving corrosion protection that works even if the surface is scratched because the surrounding zinc sacrifices itself to protect the exposed steel.
Powder coating is a decorative and additional protective layer baked onto the metal, giving a wide choice of colour and a harder finish than paint, but on its own over bare steel it doesn't offer the same self-healing protection as galvanising.
The durable combination for steel gates and railings is galvanising first, powder coating over the top, rather than powder coating alone, which is worth checking on a quote where both are mentioned separately.
