The Sequence of Works in a Renovation: What Comes First, and Why

The sequence of works in a renovation is not a habit that varies from trade to trade, nor a tradition. It is a physical necessity, and it follows from four simple principles. Once you understand them, you can work out where any new job belongs in the sequence yourself — and, more usefully, you can tell whether a programme you have been given is sound.

The price of breaking the sequence is always the same: redoing work that was already finished. Sometimes that price is small (repainting a wall); sometimes it is a significant part of the budget (lifting a new floor). And it almost always begins with "what harm would it do to change the order slightly?"

Earlier articles in this series dealt with individual rooms: bathroom renovation, kitchen renovation and renovating an older flat. Here the subject is the logic of the sequence across a whole home.

1. The four principles behind the sequence

Dirty before clean. Work that generates dust comes before work that collects it. Breaking out, screeding, sanding plaster and cutting tile fill the space with dust; polished surfaces, paint, flooring and joinery all suffer from it. Dusty work is therefore gathered into blocks and finished first.

Top before bottom. Anyone working at ceiling level drops material below. Plaster, paint and lighting start at the ceiling, come down the wall and reach the floor last. Finishing the floor first means having to protect it for the rest of the renovation; protection always fails at some point.

Hidden before visible. Everything that goes inside a wall or a floor — water, waste, power, data, ventilation — is finished and tested before it is closed up. A fault noticed after closing up takes the closing work with it.

Wet before dry. Work involving water (screed, plaster, tiling, waterproofing) needs to dry and releases moisture into the space. Timber products — flooring, doors, joinery — are affected by that moisture. So the wet work finishes, the space dries, and only then does timber come in.

These four principles do not conflict; they point the same way. When a job of uncertain position comes up, ask four questions: does it generate dust, at what level is it, is it buried, and is it wet.

2. The full sequence, step by step

1. Survey and design. Reading the existing condition, taking dimensions, layout and product decisions. This stage ends at the desk, not on site.

2. Protection and preparation. Protecting surfaces that are staying, the common parts and the lift; isolating water and power to the relevant areas.

3. Strip-out and waste removal. Everything that is coming out comes out in one block. Piecemeal demolition spreads dust across the whole renovation.

4. Structural and heavy works. Building or removing walls, adjusting door and window openings.

5. First-fix plumbing and electrics. Water, waste, ventilation, power and data. This stage ends with a pressure test.

6. Window replacement. Windows come before plaster and paint, because replacing them brings sills, plaster and decorating with them.

7. Waterproofing and screed in wet rooms. Bathroom and kitchen floors.

8. Plaster, drylining and ceiling works. Suspended ceiling framing and boarding; wall corrections.

9. Tiling and stone. Wet rooms and any other tiled areas.

10. First coats of paint (primer and mist coat). Before surfaces are closed off.

11. Flooring. Once the space has dried.

12. Internal doors, skirtings and joinery installation.

13. Sanitaryware, brassware, sockets, switches and light fittings.

14. Final coat of paint, touching up, silicone and detailed cleaning.

This sequence is a template; it does not run identically on every project. But deviations should be justified by the principles, not by "the trade is available" or "the material has arrived".

3. The three transitions that break most often

Laying the floor too early. This is the most common error, and it usually comes from wanting to "get the floor done and out of the way". Laid early, it has to be protected for the rest of the renovation: ladders stand on it, materials are carried across it, paint drips onto it, plaster dust works into the joints. Protective covering is a cost in itself and never gives complete protection. The right approach is to lay it after the dusty and wet work is done.

Finishing the paint before the installations. If the walls are painted and then doors, skirtings, joinery and sockets go in, every installation leaves a mark and the painting is done twice. The right approach is the final coat and touching up after the installations.

Closing up services without testing. Skipped to save time, this step forces you to lift new tiling and new flooring when a leak appears. The test is the cheapest insurance in a renovation.

4. What can and cannot run in parallel

A renovation is not an entirely sequential process; some works can run at the same time and shorten the programme noticeably.

Can run in parallel: the same stage of work in different rooms (plastering in one, rendering in another); joinery and window fabrication in the workshop while site work continues; material procurement and order tracking while site work continues.

Cannot run in parallel: dusty work and clean work in the same space; wet trades and timber installation; running cables and closing up walls. Attempt these at the same time and the quality of one of them will suffer.

The real issue here is coordination. A significant part of renovation delay comes not from the work itself but from trades not arriving in the right order. If the plaster has not dried when the decorator arrives, or the floor is not ready when the joiner arrives, each of them goes off to another job and weeks disappear. This is why programmes on projects run from one place are markedly shorter than those let out piece by piece. We covered the process as a whole in our article on the complete home renovation process.

5. Waiting periods that cannot be compressed

The invisible part of a programme is its waiting time. These cannot be accelerated by labour; they are the chemistry of the material.

The main ones are: drying of the waterproof membrane between coats and at the end; the screed gaining strength and its moisture content falling to a level suitable for the floor finish; drying of plaster and render; the interval between coats of paint; curing of grout and silicone; and the fabrication time for a stone or composite worktop after templating.

Shortening these gets the renovation finished early but moves the problems a few months down the line: blistered paint, opened grout, swollen flooring. If a programme looks very good to you, the first thing to check is whether these waiting periods have been allowed for.

6. When the sequence legitimately changes

There are situations in which departing from the principles is legitimate, and knowing them is more useful than applying the sequence blindly.

In renovations carried out while the home is occupied, the property is divided into zones and each zone follows the sequence internally. The aim here is to protect the area the family is using; the sequence is not broken, the scale is reduced.

Where a product has a long lead time, the stage waiting on it cannot be brought forward, but the works around it can be re-ordered. If a window is arriving late, for instance, the decoration of that room is left to the end.

If a structural problem is identified, the sequence stops entirely. Structural matters come before aesthetic decisions and work does not continue without a technical assessment.

Five common mistakes

1. Laying the floor too early. A floor that has to be protected for the rest of the renovation will end up damaged.

2. Closing up services without testing. A leak takes the finished work covering it with it.

3. Applying the final coat before the installations. Doors, skirtings and sockets leave marks; the painting is done twice.

4. Demolishing piecemeal. Breaking out that is not finished in one block spreads dust across the whole job.

5. Not writing waiting periods into the programme. Time that is not written down does not disappear; it just breaks the programme later.

Frequently Asked Questions

Does painting or flooring come first?
Primer and mist coats go on before the flooring; the final coat and touching up come after it. The floor is laid once the dusty and wet work is done; skirtings and installations follow, and the final coat completes the job along with the touching up. That way the floor does not have to be protected throughout the renovation and installation marks get covered.

What is the very first job in a renovation?
On site the first jobs are protection and strip-out, but the real first job is at the desk: survey and decisions. A renovation that starts before product and layout decisions have been made unravels as it goes. On site the sequence then follows these principles: dirty before clean, top before bottom, hidden before visible, wet before dry.

When should windows be replaced?
Before plastering and painting. Replacing windows brings sills, internal and external rendering and decorating with it; done after the painting, that work is repeated. Planning it after first-fix plumbing and electrics also allows the façade-side work to be carried out together.

Can works be carried out at the same time?
Partly. The same stage of work in different rooms can run in parallel, as can joinery and window fabrication in the workshop while site work continues. But dusty and clean work in the same space, wet trades and timber installation, and cabling and closing up walls cannot run in parallel; the quality of one of them will always suffer.

Why do renovation programmes slip?
There are three main causes: waiting periods not written into the programme, delays in material supply, and trades not arriving in the right order. The third is the most common; a tradesman who arrives to find the work not ready goes off to another job, and getting them back takes days. This is why running the coordination from one place shortens the programme noticeably.

Let us build your renovation programme together

At Kaya + Partners we manage not only the design but the sequence of works and site coordination: the works programme, tracking fabrication, ordering the trades and handover checks all run from one place. Among the interior design practices working in Ankara, what sets us apart is that design and delivery sit within the same team. For refurbishment in commercial premises, see our Ankara commercial refurbishment page.
