Facade renovation: one scaffold for every trade

A facade renovation is rarely one job. Old render comes off or the wall is cleaned, then the building is insulated or re-rendered, and the painter finishes. Each of these trades loads, uses and dirties the scaffold differently. If you know the differences before the first frame goes up, you can lay out one scaffold that carries every phase and avoid costly alterations halfway through the project.

Fix the sequence of trades first

The first planning step is the order of work. Most renovations run from coarse to fine and from top to bottom: roof and gutters first, then strip-out on the facade, then windows, insulation or render, and finally paint and finishing details. After every phase the wall looks different, and the scaffold has to suit each of those states.

Three questions follow from that sequence:

• Which trade puts the heaviest load on the deck? That trade sets the load class.
• How far will the wall grow outwards? That decides the wall distance and the number of brackets.
• Which trade produces dust, spray or falling debris? That decides on nets, sheeting and protective fans.

In short: design for the most demanding trade, usually the plasterer or the bricklayer, and for the widest final state of the wall.

What each trade asks of the scaffold

Strip-out and cleaning

The first days are usually the dirtiest. Hacked-off render piles up on the boards faster than expected, and a few buckets of old plaster weigh more than most people think. Do not let rubble build up on the decks; send it down a rubbish chute straight into the skip. Chutes hang on the scaffold, and the hopper at the top needs its own edge protection. Pressure washing or blasting produces water, slurry and dust. Sheeting shields neighbours, cars and the pavement, and the run-off must not soak the ground under the base plates.

Render

Plasterers bring bags, buckets, mortar tubs and often a render pump with hose. Several hundred kilograms per bay is normal, so plan for load class 3 (2.00 kN/m²). The lift heights matter just as much, because each lift is a potential visible joint in the finish. Details are in our guide to scaffolding for render work.

External wall insulation

An insulation system adds adhesive, board, reinforcing mesh and finish coat. With 160 mm boards the total build-up is roughly 180–190 mm (about 7 in). A scaffold that started 300 mm from the old wall ends up with little more than 110 mm of working room, which is too tight for clean work. The usual answer is to stand the scaffold further out and close the gap to the old wall with inside brackets. Ties become longer because they pass through the insulation into load-bearing masonry, and every penetration has to be sealed later. See scaffolding for external wall insulation.

New brick skin

A new outer leaf of facing brick is the hardest test for the scaffold. Take a bay of 2.57 m × 0.73 m: about 1.88 m² of deck. At class 3 that allows roughly 3.76 kN, or around 380 kg for the whole bay. Two bricklayers with tools account for about 200 kg, which leaves some 180 kg for bricks and mortar. At about 3 kg per brick that is roughly 60 bricks with no mortar at all, depending on the format a little over one square metre of wall. Bricks therefore go up in small batches spread across several bays, never a full pallet on one bay. If more material must be stored at height, plan a higher load class and check that system, bay length and decks actually reach it.

The new skin also moves the face of the building 200–300 mm forward, so the scaffold is positioned for the finished face and bridged with brackets at the start. Ties pass through the zone where the brickwork rises; the bricklayer leaves pockets that are closed after dismantling. Agree this beforehand. Bricklayers also work best between hip and shoulder height, so with 2 m lifts an intermediate platform on brackets saves hours of stooping.

Painting, windows and sills

The painter hardly loads the deck, so class 2 is enough, but needs protection against overspray and has to touch up the spots behind the ties after striking (see facade painting). Windows should be replaced before insulation and render, so the joints between frame and facade can be formed properly. New sills project beyond the finished facade: check clearances and fit flashings only once the render or insulation around that opening is done.

The top lift: eaves and roof overhang

At the top the scaffold meets the roof overhang, anything from 300 mm to more than a metre. A scaffold standing close to the wall at full height runs into the rafters or cornice, so the top lift often stops below the overhang and the last strip of render or paint is reached from there. If the roofer also needs to work, the scaffold must pass outside the overhang; the wall gap in the upper lifts then increases and inside brackets close it. Settle this with the roofer before the first lift goes up, because changing it later affects the whole scaffold.

These are planning values from practice. Binding are the manufacturer's instructions for assembly and use of your system and the requirements of the contractors, including which load class the system reaches at which bay length (see load classes and width classes).

Nets, sheeting and the tie pattern

A debris net stops tools and lumps of render while letting most of the wind through. Sheeting keeps dust, spray and rain in far better, but catches the full wind. The denser the cladding, the tighter the tie pattern has to be. Never add sheeting to a scaffold that was not designed for it: a rain screen fitted as an afterthought in autumn changes the structural behaviour of the whole scaffold. Decide on cladding at the design stage: nets for the whole renovation, sheeting only where it is really needed, for example on the street side or facing the neighbour.

Long standing times and alterations

The more trades, the longer the scaffold stays. Several months are common on a full renovation, and in that time brackets are moved, ties relocated and decks changed. Only a competent person may make these alterations, and that person inspects the scaffold again afterwards. Someone working on the scaffold must not remove a tie because it is in the way. Under the UK Work at Height Regulations 2005, a scaffold is checked before first being put into use, again at intervals of no more than seven days, and whenever weather or an incident may have weakened it. US contractors work to OSHA, which wants the scaffold looked over by a competent person ahead of every shift. In other countries, the national rules apply.

A short handover between trades works well: the plasterer says where ties should move, the painter says whether sheeting is needed. Long standing times are also an argument for owning the scaffold: if one trade slips by two weeks, the scaffold simply stays without extra cost (see buying or hiring).

Checklist before erection

• List of all trades with sequence and approximate duration
• Load class chosen for the heaviest trade
• Wall distance calculated for the final state, including insulation, render or brick skin
• Enough inside brackets planned
• Cladding decided and included in the tie pattern
• Agreed who moves ties and who fills the holes
• Rubbish chute or another route for demolition waste
• Access positioned to suit all trades
• One person who coordinates and inspects every change

For most detached and semi-detached houses, a frame scaffold 0.73 m wide in load class 3, supplemented with inside brackets, is a solid basis. Work out quantities with the scaffolding calculator and browse used facade scaffolding. As an indication (October 2026), complete used frame packages cost roughly €30–40 per m² plus VAT, with lower rates per m² for large areas.
