Renovating an older apartment: what to keep, repair or replace

Start with what no longer works

Before collecting finish samples, write down the problems you want the renovation to solve. Perhaps the kitchen cannot accommodate everyday cooking, the entrance lacks storage, or the bedrooms need better privacy. Separate these needs from changes you would simply enjoy.

Bring an existing plan if available, a room-by-room photo record, the apartment’s approximate age and any history of leaks or previous repairs. Photographs help prepare a visit; they cannot establish the condition of concealed work. Agree what the initial assessment covers and what may require further specialist inspection.

Give every element a keep, repair or replace decision

Walk through the apartment with a simple schedule covering floors, doors, windows, walls, ceilings, cabinetry and services. For each item, record its apparent condition, whether it suits the proposed use, and what must be checked before deciding. Add a fourth status: inspect before committing.

• Keep: useful elements whose condition and compatibility have been checked.
• Repair: elements with a defined repair scope and an acceptable expected finish.
• Replace: elements that cannot reasonably support the agreed requirements.

For retained finishes, agree a sample or reference for what “acceptable” means. An old door can have character without needing to look newly manufactured.

Resolve service questions before selecting surfaces

Ask appropriate specialists to assess the existing electrical, plumbing, drainage and ventilation arrangements against the new plan. Their age alone does not settle whether to retain them, and a freshly painted surface does not confirm their condition. Record inaccessible areas and any agreed investigation needed before the final scope is fixed.

Recurring damp marks or damaged finishes need the cause assessed before they are covered. Structural concerns and proposed changes to walls require a qualified professional’s review. Treat each finding as a decision with a responsible person, a next step and a budget implication.

Test the new layout against what stays

Retaining a floor or built-in unit is worthwhile only if it works with the future plan. Check furniture positions, door swings, appliance access, service locations and the joins between old and new work. A cabinet that fits today may obstruct the circulation the new design is meant to improve.

If a new floor is proposed over existing tiles, ask the installer to confirm the base and chosen product are compatible. Flatness, moisture, stability and finished levels need checking; adding a layer is not an automatic shortcut. Door clearances, thresholds and adjacent rooms belong in the same decision. The flooring comparison guide explains what to ask before choosing a system.

Plan access and daily life alongside the design

Decide early whether the apartment will be occupied during the work. A phased programme should identify usable sleeping, washing and cooking arrangements, protected storage, and periods when services may be interrupted. Ask the contractor which activities cannot reasonably happen alongside normal occupation.

Confirm building access arrangements, delivery routes, lift protection, working hours and waste removal with the relevant building management. These practical details can change the sequence of work. Include protection and reinstatement of retained elements in the scope, and record their condition before work begins. A plan that respects the building and its residents is more useful than a completion date detached from the actual site constraints.

Compare scopes before comparing totals

A useful renovation proposal identifies quantities, retained items, repair allowances, exclusions and decisions awaiting inspection. Ask how newly discovered conditions will be priced and approved before additional work begins. Keep optional upgrades separate so you can make deliberate choices without losing sight of essential work.

Compare proposals on the same basis, including protection, removal, making good, installations and handover information. The apartment finishing budget guide can help structure that discussion. Once the retain-and-replace decisions are clear, connect them to a realistic sequence of work. Your first deliverable should be a reasoned renovation scope, not a demolition list.

Common questions

Can I renovate without removing every existing finish?

Often, selective retention is possible. The decision depends on condition, the new layout and compatibility with adjoining work. Confirm each retained item in the scope rather than assuming everything can stay.

Can a renovation price be confirmed from photos alone?

Photos support an initial conversation, but they do not reveal concealed conditions or confirm measurements. A site assessment and clearly stated assumptions are needed before relying on a detailed proposal.

Should I choose the finishes before the assessment?

Collect references early, but delay irreversible purchases until the layout, existing conditions and installation requirements are understood. This reduces the chance of buying a finish that cannot be used as intended.
