What Determines How Long a Renovation Takes

How long a renovation lasts depends on scope, curing and drying breaks, material deliveries, decision speed and building rules. Knowing these factors lets you plan a realistic timeline.

“When will it be finished?” is one of the questions clients ask most. An honest answer is impossible without seeing the property, because the timeline is set not by the number of workers but by the sequence of tasks and the unavoidable pauses between them. Knowing what stretches a renovation helps you set realistic expectations and prevent some delays altogether.

Scope and sequence of work

A renovation is made up mostly of sequential rather than parallel tasks. After demolition come electrical and plumbing runs, then plaster and screed; once they dry, tiling, ceilings, painting and flooring follow, and finally doors, sanitary ware and light fittings. One stage cannot start until the previous one is complete.

When the layout changes, new partitions go up or the bathroom moves, new links are added to the chain. Multi-level ceilings, decorative wall finishes and intricate tile patterns also add time.

The make-up of the team matters as well. When too many workers share one room they get in each other’s way, so adding people does not shorten the timeline proportionally. A more effective approach is to identify in advance which tasks can run in parallel in different rooms and to sequence specialists – electricians, tilers, painters – so that when one finishes, the next is ready to start.

Curing and drying periods

Some work simply cannot be rushed. Screed, plaster, skim coats and waterproofing layers need to dry, and the manufacturer’s waiting times must be respected. Parquet or laminate laid on a damp base, or paint applied to a wall that has not fully dried, will show defects later.

Drying speed depends on room temperature, ventilation and humidity, so the same job can take longer in a cold, damp season. These pauses should be built into the schedule from the start; otherwise it looks as if nobody is working, when in fact the material is just drying.

Supply of materials and made-to-order items

Standard stock items arrive quickly, but tiles in a special colour, imported sanitary ware, custom doors and windows, a staircase or stone worktops need production and delivery time. Because these are made to measure, the measurement itself often has to wait for a certain stage: a worktop, for example, is templated only after the kitchen units are installed.

A large share of delays starts right here: the site is ready, but the materials are not. Ordering long-lead items at the very beginning protects the schedule.

How quickly decisions are made

The client’s decisions are part of the timeline too. When the choice of tiles, paint, lighting points or sanitary ware is delayed, workers either wait or move to another task and come back later. A change of mind during the works means tearing out and redoing what is already done.

A renovation that starts with a finished design project and an approved list of materials is usually far more predictable.

Regular site visits or following progress through photo reports also speed up decisions, because workers do not wait days for an answer when a question comes up. Agreeing on a communication channel and a response time in advance prevents small pauses that add up to weeks.

Conditions in the building and on site

In a residential building, noisy work is allowed only during permitted hours. No goods lift, carrying materials upstairs, removing waste and finding space to park a van all reduce productive hours. If an office or café has to keep operating and the works are split into phases, the timeline grows accordingly.

In older buildings, hidden problems discovered once walls are opened also take extra time. It makes sense to allow some slack in the schedule for such cases.

Renovating while living in the flat is a separate case. Rooms are cleared one at a time, furniture is moved around, and dust and noise limit some work to certain hours. It can be done, but you should accept from the start that it will take longer than renovating an empty flat.

What you can do to protect the timeline

• Start with a design project and an approved materials list.
• Order long-lead items first.
• Show drying periods as separate entries in the schedule.
• Identify decision points and their deadlines in advance.
• Clarify building rules and working hours with the contractor.
• Approve changes only after you know how they affect the timeline.
