The Complete Renovation Sequence for a Period London Property

Why the Sequence Matters More Than You Think

The most expensive mistake in a period property renovation is doing work in the wrong order. A full redecoration followed by skirting removal for a new underfloor heating circuit. A freshly plastered ceiling cracked by a structural engineer who needed access two weeks later. An expensive paint job on a wall that then had to be cut through for a new electrical ring main.

In a period London property — a Victorian terrace, an Edwardian conversion flat, a Georgian townhouse — the renovation sequence is complicated by the age and complexity of the building fabric: lime plaster that behaves differently from modern plasterboard, cast iron or lead pipework, timber floors over voids, and walls that have been worked on by many different hands over many decades. Getting the sequence right from the start saves money, avoids rework, and means that the decoration — which is the work people actually see every day — is applied onto a properly prepared substrate rather than a compromise.

Phase 1: Structural and Survey Work

Before anything else, address the building's structural condition. This means:

Structural engineer's assessment if there are cracks, movement, or proposed alterations
Party wall surveys if the work involves the party wall
Damp surveys if there is evidence of rising damp, penetrating damp, or condensation
Any underpinning, needle-and-prop work, or structural steel installation
Roof repairs, chimney repointing, lead flashing, or valley gutter replacement

Damp investigation deserves particular attention. A significant proportion of period properties in London have some form of damp, and many have been incorrectly diagnosed and treated. Modern chemical injection damp-proof courses applied to Victorian lime-mortared brickwork are frequently ineffective — Victorian brickwork is designed to be breathable, and introducing a chemical barrier into the mortar joints rarely solves the underlying problem. If in doubt, get an independent damp survey from a surveyor who is not also selling the remedy.

Structural and damp work must happen before any internal trades begin. Anything else is building on uncertain ground.

Phase 2: First Fix — Mechanical and Electrical

Once the building is structurally sound and damp issues are resolved, first fix trades begin:

Electrical rewire (or partial rewire) — new consumer unit, ring mains, radial circuits, lighting circuits
Plumbing first fix — new pipework for bathrooms, kitchen, heating flow and return
Central heating installation — if replacing an old system, boiler location, radiator positions, underfloor heating
MVHR or mechanical ventilation if being installed
Structural openings for new door positions, RSJs above openings, and any new window openings

All of this work involves cutting into walls, floors, and ceilings. It is invasive, messy, and unavoidably damaging to existing plasterwork. Nothing should be made good until all first-fix trades have completed, been inspected, and signed off. The number of times we have been called back to repaint a wall that was then cut into the following week is not small.

Phase 3: Plastering and Making Good

Once first fix is complete and inspected, the plasterer can make good all the chases, cut-outs, and damaged areas. In a period property this is more complex than in a modern house:

Lime plaster — found in pre-1920 properties and sometimes later — should be repaired with compatible lime-based materials. Gypsum plaster applied over lime can cause problems: differential movement cracking, bonding failures, and in some cases efflorescence. A good plasterer working on period properties will know this and will use a bonding coat compatible with the existing substrate.

Lath and plaster ceilings — common in Victorian and Edwardian properties — should not automatically be replaced. A bulging lath-and-plaster ceiling can often be reinstated with proper consolidation screws and careful filling, preserving the original fabric and avoiding the cost of a complete replacement. If replacement is necessary (severe damage, multiple layers of old fibrous plaster, structural issues), match the original profile before replastering.

Coving and cornice repairs — period plasterwork cornices should be repaired in-kind. Cast in-place plaster cornice repairs use the same section as the original, run using a zinc or aluminium profile made to match. Fibrous plaster sections can be matched from specialist suppliers. Polystyrene coving as a replacement for original cornice is always a mistake.

Allow sufficient drying time after plastering before proceeding. Fresh gypsum plaster requires a minimum of four weeks per 5mm of thickness before painting — and in a London winter with poor ventilation, longer. New lime plaster dries even more slowly and may require months before it is ready for decoration.

Phase 4: Joinery and Second Fix

With the plaster dry and in good condition, joinery and second fix can proceed:

New internal doors, frames, and linings
New skirting boards and architraves (where existing were removed for first fix)
New staircase components if the stair was altered
Window board renewal where sills were damaged
Second fix electrical — sockets, switches, lighting pendants, consumer unit connections
Second fix plumbing — sanitaryware installation, radiator installation, kitchen sink and appliances

This phase leaves the property looking nearly complete. Skirting boards will be in, doors will be hung, and the room will have its final shape. But this is also the point at which any minor plastering deficiencies become clearly visible, and they should be addressed now — stopping, light skimming, or full patch plaster — before decoration starts.

Phase 5: Preparation and Decoration

With all trades complete and the property cleaned out, the decorators can begin. The sequence within decoration itself matters:

Ceilings first — protect floors and completed walls from splatter
Walls — cut in at cornices and skirtings, full application
Woodwork last — doors, skirtings, architraves, window frames in gloss or eggshell

In a period property with ornate plasterwork, allow extra time for cornice and ceiling rose work: a complex run of original Victorian cornice properly rubbed down, primed, and painted in three coats with a fine paint brush takes considerably longer than rolling a modern ceiling.

Do not rush the preparation. On a Victorian property that has had many previous paint layers, the preparation — rubbing down, stopping dents and cracks, filling nail holes, sanding back ridges — can account for 40% of the total decoration time. It is never glamorous, and in a week-by-week review of progress it can look like nothing is happening. It is, however, what distinguishes a finish that lasts ten years from one that looks tired in eighteen months.

Phase 6: Floor Finishing and Specialist Trades

Floor finishing — sanding and sealing original floorboards, laying new flooring — happens after painting is complete. Any paint splatter on bare boards from the decorating phase should be removed before the floor sander arrives. Specialists such as tile layers, kitchen installers, and built-in joinery fitters also work in this phase, after the painted surfaces around them are complete.

Common Sequencing Mistakes to Avoid

Painting before all plasterwork dries. New plaster painted too early will have the paint lift and peel within months as moisture pushes out through the surface.

Decorating before all trades are done. If anyone still needs access above a ceiling or through a wall, the decoration will be damaged.

Painting over bare MDF skirting without primer. MDF end-grain sucks paint; it needs priming with a diluted coat or a specific MDF sealer before topcoats.

Gloss on joinery before it has settled. New softwood joinery in a period property may move slightly in the first heating season. A full-gloss finish on new joinery can crack at movement points. Eggshell is more forgiving.
