House Interior Finishing Sequence: What to Prepare Before the Tradespeople Arrive?

Fitting out a home starts not with buying filler or flooring, but with decisions that determine the work that follows. An unapproved kitchen layout, unclear floor levels or uncoordinated lighting positions can mean having to revisit surfaces that have already been finished. Before the tradespeople arrive, it is important to distinguish between two things: what is needed for the site inspection and what is needed to actually start work.

This guide provides an indicative sequence. For a particular house, it must be adapted to the existing condition, the design, the selected materials and their technical requirements.

1. Before the inspection: provide information rather than trying to fix everything

You do not need to have purchased all the materials for the first inspection. It is much more useful to prepare information that helps clarify the scope of work and any decisions still to be made.

• Floor plan and available documents: dimensions, design details and building services plans, if prepared.
• Description of the current condition: what has been completed, what remains unfinished, and where moisture, cracks or other defects have been noticed.
• List of required work: separately indicate what is excluded or will be carried out by other specialists.
• Photos: general views of the rooms, problem areas and services that have not yet been covered.
• Planning constraints: the desired deadline, budget limits and decisions you are still unsure about.

Do not hide known defects beneath finishes just to make the site look ready. It is better to establish their cause and the extent of repairs before the finishing work.

2. Which decisions need to be made before work starts?

A visualisation helps convey the interior’s appearance, but it does not replace dimensioned plans. Tradespeople need to know not only how a room will look, but also exactly where equipment, connection points and finish junctions will be located.

• Furniture and kitchen. Coordinate the layout of fixed furniture, appliances and work areas with electrical and plumbing connection points.
• Sanitary fixtures. Confirm their positions, the installation requirements of the selected models and access to components requiring servicing.
• Lighting and electrics. Mark light fixtures, switches, sockets and control groups.
• Floors and doors. Coordinate flooring types, their layer heights, junctions and door installation details.
• Wall and ceiling finishes. Discuss the final finish and expectations for surface preparation.

Simply agreeing that “the walls must be smooth” is not enough. Knauf’s surface filling recommendations describe preparation levels Q1–Q4. The applicable level should be agreed based on the substrate system, intended finish and lighting conditions, rather than treating one level as universal for all rooms.

3. Interior finishing sequence: what should be checked between stages?

The start of a stage should depend not just on a calendar date, but also on the condition of the preceding work. The table below helps discuss dependencies between tasks. It is not a universal technical guide: some tasks may be carried out in parallel or in a different order.

Before covering building services, it is useful to save photos and measurements of their locations. Photos do not replace required tests or documents, but they help with orientation during later installation and maintenance work.

4. Drying and moisture: why is looking at the surface not enough?

A substrate that looks dry is not necessarily suitable for the next layer. The Knauf Super Finish recommendations state that the substrate must be dry, sound and free of contaminants that interfere with adhesion. Damage must be repaired before final filling.

A specific Quick-Step laminate installation guide requires substrate moisture to be measured and the results retained. Permissible values depend on the substrate and underfloor heating, so they cannot automatically be applied to other floor coverings.

In wet areas, waterproofing details must be checked before laying tiles. For example, the Ceresit CL 51 technical document specifies separate sealing of corners, joints and service penetrations using system components. These are requirements for a specific product, not instructions for all waterproofing systems.

There is no single drying time, moisture limit or working temperature suitable for all materials. Agree in advance who will take the required measurements, where the results will be stored and how readiness for the next stage will be confirmed.

5. Materials and site: what should be prepared for the tradespeople’s arrival?

Products with long lead times should be planned early, but orders should only be confirmed once their technical specifications have been agreed. Delivering all finishing materials on the first day may obstruct work or make proper storage difficult.

• Agree who will check material compatibility, calculate quantities and order missing items.
• Assign responsibility for delivery, unloading and accepting products.
• Plan storage areas according to manufacturers’ requirements and keep passageways clear.
• Agree on key handover, working hours, vehicle access and unloading arrangements.
• Discuss the provision of electricity, water, lighting and welfare facilities.
• Allocate responsibilities for protecting existing surfaces, cleaning and waste removal in writing.

6. Site start-up checklist

This checklist can be copied into a shared document. For each item, enter “ready”, “to be agreed” or “not applicable”, the person responsible and the deadline.

1. The plan, photos and available project documents have been handed over.
2. Completed work and known defects have been described.
3. The work list and clear exclusions have been confirmed.
4. Furniture, kitchen, plumbing and lighting details have been agreed.
5. It has been agreed who will check substrates and record measurements.
6. The conditions for starting each stage have been defined.
7. Responsibilities for supplying and accepting materials have been allocated.
8. Access, storage areas and surface protection have been prepared.
9. Waste management and site cleaning have been agreed.
10. A procedure for approving additional work has been established.

A simple table is sufficient for changes: change – reason – price change – deadline change – who approved it and when. This is a suggested organisational tool, not a procedure declared by a specific company.

7. When is it necessary to consult a designer?

An interior finishing plan does not replace structural or building services designs. If you intend to alter potentially load-bearing structures, create openings, increase loads, relocate wet areas or significantly modify building services, first consult a designer in the relevant field. They will help determine the required design details and documents.

Unexplained cracks, recurring moisture or leaking systems should not simply be covered up. The cause must first be identified; only then can substrate repairs and finishing be planned.

8. What should you provide for an individual cost assessment?

Provide the site location, plan, photos of its condition, a work list and available design details. When comparing quotes, check whether substrate repairs, preparation level, materials, delivery, protection and waste management are included on the same basis. Clarify unclear items before agreeing on the start of work.
