Understanding exactly what happens from the first visit to the last post in the ground helps you plan around the work - here is how Haverhill Fencers approaches a metal fencing installation near Newmarket.
A properly priced metal fencing job starts with someone walking the boundary, not with a quote over the phone. Ground conditions, access, what is being removed, and whether the line of the fence follows a straight run or involves changes of direction all affect the price and the time the job takes. A site visit is the only way to find out.
During the visit, a few things get checked that customers do not always think about in advance. The ground type matters: solid clay, chalk, sandy soil and made-up ground (old rubble or fill) all behave differently when posts are being driven or bored in. If the ground is very hard, mechanical post-boring may be needed; if it is soft or sandy, the concrete bases need to be larger to hold the post firmly. Both affect the cost.
The line of the fence also gets walked carefully. Boundaries are not always where people think they are, and a fence installed 100 mm into a neighbour's land can cause significant problems later. If there is any uncertainty about the boundary line, this is worth resolving before posts go in, not after.
Once the site has been assessed, the job gets measured properly - linear metres of fencing, number of gate openings, post positions, and any changes in level along the run. A fence on a slope either has to follow the slope (raked) or step down in level sections. Both approaches are used depending on the fencing system; some metal fencing systems are supplied for raked installation, others are designed to step. This has to be confirmed before materials are ordered.
Post spacing is specified at this stage. For most steel and aluminium railing systems, posts sit between 2.0 and 3.0 metres apart. Wider spans can be used but the rails flex more and the visual effect is less crisp. Closer spacing adds cost but improves rigidity, which matters for longer runs and for fencing near driveways or gates.
Gate positions are confirmed at the measuring stage. It is important that gate posts are set slightly wider than the gate leaf to allow for the width of the hinges and a small operational clearance. Ordering the gate before the posts are set, or at least confirming the exact opening width before ordering, avoids the common problem of a gate that will not hang squarely in its frame.
If there is existing fencing to take out, this is normally the first task on the installation day. Timber panels and posts come out by hand and with a bar; concrete spurs and old metal posts set in concrete take longer and may require mechanical assistance. The time this takes is often underestimated, particularly if old timber posts have been in the ground for many years and the base concrete is substantial.
Old concrete bases are either broken up and removed, or cut down below finished ground level and left in place - which approach is used depends on whether the new post sits in the same position and how deep the old base goes. A new post set directly on top of a broken old concrete base without full excavation is a shortcut that will cause problems later. The base needs to be sound and level for the new post to sit true.
Post setting is the part of a metal fencing installation where cutting corners has the most visible and lasting consequences. A post that is slightly out of plumb or not set to the correct depth will make the whole run look wrong and may fail structurally sooner than it should.
Posts are typically set using one of two methods: driven into the ground using a post rammer (faster but only suitable for certain ground conditions and post types), or bored into the ground and concreted in. For steel and aluminium railings, concreting in is the standard approach. The hole is bored or dug to the required depth - typically at least 600 mm, often deeper for taller fencing or on exposed sites - the post is positioned, checked for plumb in both directions using a spirit level, braced upright, and then concrete is poured and allowed to cure.
Concrete needs time to cure before the rest of the fencing is assembled. In most conditions, posts should be left for at least 24 to 48 hours before rails and panels are fixed. Rushing this stage and loading the posts before the concrete has set properly can shift the post position before it is locked in.
Once the posts are set and the concrete has cured, the rails and infill sections are fixed. For pre-fabricated aluminium and steel railing systems, this involves bolting panels into the posts at pre-drilled fixing points. The fixings are usually stainless steel or plated to resist corrosion; using the wrong fixings here causes premature rust staining on what should be a clean finish.
Where fencing runs on a slope, the panels are stepped or raked to follow the ground. Stepped panels leave a gap between the bottom rail and the ground at the lower end of each section; this is normal and expected, but if the gap needs to be closed (for pet containment, for example) it has to be planned for at the specification stage, not addressed after the fencing is up.
Cut ends of steel sections are treated with cold galvanising spray or zinc-rich primer on site before the fence is assembled. This step is easy to skip when a job is being rushed, and skipping it is one of the main reasons cut edges begin rusting within a year of installation.
Gates are hung once the gate posts are fully set and cured. The hinges are fixed to the post first, then the gate leaf is offered up and adjusted until it swings freely and closes squarely against the latch post. Getting the hinge positions right takes time; a gate hung slightly out of true will bind, drag, or fail to latch without being lifted.
If the gate is being prepared for automation, the operator bracket positions need to be confirmed before the gate is hung, as the operator arm connects to a specific point on the gate leaf and post. Retrofitting automation to a gate that was not set up for it is possible but messier and more expensive than allowing for it from the start.
Once all panels and gates are in place, the fixings are checked and tightened, the line of the fence is walked again to confirm it is running true, and any site waste - old fencing, concrete spoil, packaging - is cleared. The ground at the base of each post is made good, and any areas disturbed during excavation are tidied back.
The customer should walk the fence line with the installer before signing off on the job. Check that gate leaves swing fully without binding, that all fixings are present and tightened, and that the base of the fence is sitting at the right height relative to the ground throughout the run. These are the things easiest to resolve on the day and hardest to come back to correct after the installation team has left.
A well-installed metal fence runs in a true, straight line between gate openings or changes of direction. Posts are plumb, panels are level or correctly raked, and there is no visible twist or deflection in the rails. Gate leaves close squarely and latch without being lifted or forced. Fixings are the correct type for the material and show no rust staining. Cut ends have been treated. The base of the posts is sound and the ground is made good around them.
Any of these things missing from a finished installation is a sign that care was not taken somewhere in the process described above.
