What Happens During a Tree Surgery Job: From Quote to Clean-Up

A domestic tree surgery job runs through six stages: site visit, written quote, protection check and any statutory notification, the work itself, waste processing, and clean-up. On an unprotected tree with vehicle access, the gap between first contact and completion is usually one to three weeks. On a protected tree, it is at least seven.

Most of that difference is administrative, not operational. The stages below explain where the time goes and what happens on the day.

The site visit: what the arborist is assessing

A site visit lasts twenty to forty minutes for a domestic garden. Four assessments run in parallel.

The tree itself. Species, height, crown spread, stem diameter, structural condition, decay indicators at the base and in the main unions, deadwood, and the presence of pests or fungal fruiting bodies.

The target. What sits beneath and beside the tree, the house, a conservatory, a greenhouse, a neighbour's roof, overhead cables, a shared boundary. Targets determine whether limbs can be dropped or must be lowered on ropes, and lowering everything roughly doubles the time on a large removal.

Access. Distance from the nearest hard standing to the tree, gate widths, whether a chipper can reach the arisings or whether every branch must be carried out by hand. Access is normally the largest single variable between two quotes for visually identical trees.

Legal and ecological constraints. Protection status, and whether the tree shows signs of an active bird nest or features that could support roosting bats.

Access is where Winchester properties diverge sharply from the county average. Terraced streets in Fulflood, Hyde and St Giles Hill frequently have no rear vehicle access at all, which means every section of timber leaves through the house or over a flint boundary wall by hand. Properties in the historic core often need a parking bay suspension arranged with the local authority before a chipper and tipper can be positioned, and those suspensions typically require several working days' notice. Both add labour hours rather than complexity, and both should appear as a stated assumption in the written quote rather than as a surprise on the day.

Checking protection status before the quote is issued

Protection status is confirmed before pricing, because it changes the timeline more than the price.

Winchester City Council publishes TPO and conservation area boundaries through its public mapping service, with separate layers for individual TPO trees, group TPOs and conservation areas. The council treats the mapping as indicative and asks that status be confirmed with the tree team directly on 01962 848 301 before work is planned.

Two different regimes follow from that check. A Tree Preservation Order requires a formal application for consent, which the council determines. A tree in a conservation area without a TPO requires six weeks' written notice instead, during which the council may respond by making a TPO. Neither carries a fee.

The practical effect is a fixed seven-to-nine week gap between quote and start date on most protected trees in Winchester. A contractor who submits the notification or consent application on your behalf removes the administrative work, but no contractor can shorten the statutory clock. Any offer to do so should end the conversation.

The morning of the job: what the crew sets up first

Work does not start with a saw. It starts with a site-specific risk assessment and method statement covering the drop zone, the rigging plan, overhead services, exclusion zones and the emergency route.

The rescue plan is what dictates crew size. A climber working aloft must have a ground worker trained and equipped to perform an aerial rescue, because a climber who is injured or unconscious in the canopy cannot self-recover. That is why a two-person crew is the minimum on any climbing job, and why a single operative arriving alone to climb a tree is a health and safety failure before any cutting begins.

Setting up takes twenty to forty minutes and includes cordoning the work area, positioning the chipper and tipper, protecting lawns and paving where machinery will track, and a final visual check of the canopy for nesting birds. Active nests are protected under the Wildlife and Countryside Act 1981 and stop non-urgent work outright.

Rigging and sectional dismantling: how a large tree comes down

A tree in an open field is felled in one piece. A tree in a Winchester garden almost never is.

Sectional dismantling means the climber works from the top down, removing the tree in pieces small enough to be controlled. Each section is either dropped into a clear zone or lowered on a rigging line through a friction device at the base, which allows the ground crew to control the descent speed and set each piece down rather than letting it fall.

Rigging is used wherever a dropped section would strike something. The technique is slower, every piece is tied, cut, lowered, untied and cleared, and the time cost is the main reason a removal beside a conservatory prices higher than the same tree in an open lawn. The mechanics of safely removing a large tree in a confined garden are worth understanding before comparing quotes, because a contractor pricing to drop sections in a space that requires lowering them is pricing a different and more dangerous job.

Pruning work follows the same logic in reverse. The climber moves through the canopy making cuts to defined points, and the cut material is either dropped clear or lowered. Timing matters for the tree's recovery, and the best months to prune each common garden species vary enough that a job booked in the wrong season can cost the tree more growth than the pruning itself.

Chipping, cordwood and what leaves the site

Brash goes through the chipper as work proceeds, which is why the noise on a domestic job is intermittent rather than constant. Larger-diameter timber is cross-cut into rings and either loaded out or stacked.

The arisings are the homeowner's property. Retaining the cordwood for firewood reduces the volume leaving the site and can reduce the disposal element of the price, and woodchip can be retained for mulching borders. Chip from a diseased tree should leave the site rather than be spread.

Whatever leaves must go with a registered waste carrier. A householder has a legal duty of care to pass waste only to an authorised carrier and can face a fixed penalty of up to £600 where that waste is later fly-tipped. Ask for the registration number and keep the invoice.

Stump grinding and what it leaves behind

Stump grinding is a separate operation, often on a separate day, because the grinder is a different machine that needs its own access route.

The cutting wheel removes the stump and major surface roots to a set depth, typically 150–300mm below ground level, with deeper grinding available where replanting or building work is planned. What remains is a hole filled with a large volume of chip and soil mixed together.

That mixture matters for anything planted afterwards. Decomposing woodchip locks up nitrogen as it breaks down, so replanting in the same position usually means excavating the arisings and importing topsoil. Homeowners planning to plant into the same spot should confirm the intended grinding depth and what happens to the resulting chip at quote stage rather than after the machine has left.

Grinding does not remove the entire root system. Lateral roots remain and decay in place over several years.

Clean-up, aftercare and the weeks afterwards

Clean-up means the work area returned to its previous state: sawdust blown or raked off hard surfaces, borders cleared, the drop zone swept, and the gate closed behind the crew. A tidy site is an expectation, not an extra.

Three things follow in the weeks after.

Regrowth. A reduced or thinned crown produces new shoots in the following growing season. Dense, vertical epicormic growth after pruning indicates the reduction was too heavy for the species and the tree is responding to stress.

Light and lawn changes. Removing or reducing a large tree changes light levels underneath it. Grass that was previously shaded typically takes a season to establish.

Documentation. Keep the invoice, the waste carrier number and any council correspondence together. Where a tree was protected, that record is the evidence the work was lawfully notified, and it is the paperwork a conveyancing solicitor asks for at the point of sale.

Costs for each of these stages vary by access, species and disposal route rather than by height alone. The full breakdown of what drives a tree surgery quote across Hampshire sets out which of the six stages above tends to carry the largest share of the total on a typical domestic job.
