You might hear it be called sectional felling, tree dismantling, or a sectional tree removal. All three describe the same dismantling services.
A climbing arborist works up through the crown, cutting the tree into sections one at a time and lowering each one to the ground on ropes.
It’s a complex tree removal technique that requires planning every cut before the chainsaw starts. It takes longer than a standard fell and costs more, but it’s often the only safe method of removing a tree that’s boxed in by fences or power lines close enough to make a fall risky.
How big the sections are – Guide by tree surgery Glasgow experts
How big each section is depends entirely on what’s around the tree.
Our tree surgeons work that out during the survey, before any cutting begins.
In an open garden, they might take down manageable sections of four or five metres without a second thought. Squeezed between two houses, those same sections shrink to arm’s length, controlled the whole way down using ropes and a pulley.
Our climbing team holds the City & Guilds NPTC Level 3 Award in Aerial Tree Rigging. It’s the qualification this kind of tree care requires.
When a tree needs to come down in sections
Confined spaces
Back gardens and tenement courtyards rarely leave room for a tree to fall its own height.
If a leylandii stands twelve metres tall in a garden eight metres wide, felling it whole isn’t an option whichever direction you aim it.
Sectional dismantling lets us take the tree apart from the top, one length at a time, without the clearance a full fell demands.
Near buildings and power lines
A tree growing right up against a garage or a boundary wall carries the same problem from a different angle, and overhead power lines raise the stakes further still.
Even a controlled fell can clip a roof or damage nearby structures if the trunk doesn’t behave exactly as planned.
Removing trees in confined spaces like this calls for a tree surgeon who can climb, rig, and lower each section clear of whatever it’s near.
Damaged, diseased, or storm-hit trees
Wind damage and disease change the calculation again.
After a winter storm, a storm-damaged tree can look stable from the ground while the top third is barely holding on.
A tree with dead wood in the crown or a split trunk doesn’t behave predictably once the first cut goes in, so removing the tree section by section keeps the crew safe even when the tree itself is unstable.
How our tree surgeons dismantle a tree safely
Climbing and rigging
One of our qualified arborists climbs the tree on ropes and a harness, working out anchor points before any cutting starts.
Rigging slings and pulleys get fixed at strong points higher in the crown, letting the ground crew control the descent of each section and lower it precisely where they want it.
Anchor points are checked and rechecked, because the whole system depends on them holding under load. On the heaviest sections, or where rigging alone can’t take the weight safely, we bring in a crane to lift the piece clear instead.
Our tree surgeon plans the whole sequence before the saw goes anywhere near the tree: which sections come down first, and where each one will land. The climber and the ground crew coordinate with hand signals throughout.
Cutting and lowering sections
From there, the climber cuts the smaller branches first, then works down towards the trunk, taking progressively larger sections as the diameter increases.
Each piece is lowered to the ground under rope tension, guided so it lands exactly where the ground team can handle it.
On a tricky job close to a house, sections might be no bigger than a fence post.
On a more open site, entire branches can come down at once, because there’s room to let the rope run.
Once complete, we can safely remove tree stumps to help you reclaim your outdoor space.
Sectional dismantling vs full tree felling
Felling a tree in one piece is faster and costs less, and it’s what we’d recommend whenever the space allows it.
Sectional dismantling is often more expensive, because it only gets used when the surrounding environment doesn’t leave a fell as an option, whether that’s a fence six feet from the trunk or a conservatory roof under the canopy.
Both are safe when matched to the site correctly. For your garden, the deciding factor is simply what’s in the way of a straight fall, a fence, a wall, or a power line overhead.
Sectional dismantling takes longer, because the removal of trees this way is slower work than a straightforward fell.
A fell that takes an hour can stretch to most of a day in sections, because every cut needs planning and every piece needs lowering under control instead of just cutting and stepping back.
Safety, equipment, and planning
Sectional dismantling depends on the right kit and a realistic risk assessment before the saw comes out.
This is especially important on a tree with rot or cavities hidden in the crown, or a history of storm damage nobody’s inspected yet. Our climbers wear full personal protective equipment rated for aerial work, and every job starts with a walk-round to flag potential hazards specific to your garden.
Our tree care professionals match their tree cutting methods and rigging gear to the tree in front of them.
A young sycamore and a mature oak call for different handling, based on size, species, and condition.
Get a tree surveyed before you decide how it comes down
Check whether a tree preservation order applies before any tree comes down, whichever method fits, and confirm whether you need permission from the council at all.
We check this as part of every survey, because removing a protected tree without the right permission carries real penalties.
If you’ve got a tree too close to call safely from the ground, whether that’s overhanging a shed in Cambuslang or leaning towards a bungalow in East Kilbride, get in touch now.
Storms don’t wait for a convenient time.
Our arborists are certified through the Arboricultural Association and hold the City & Guilds NPTC aerial rigging award. They’re the same team behind Scotland’s Best Landscaping Company 2024.
We’ll survey your garden and everything around the tree before recommending whether it needs a full tree removal or dismantling piece by piece.
