Old apartments have character but tired infrastructure. With the right expectations and a budget buffer, these projects run smoothly.
The most common surprises in old buildings
- •Corroded galvanised water pipes
- •Old wiring that no longer meets code
- •Uneven, sloping floors
- •Damp and insulation problems
Why a contingency is essential
In old flats hidden issues only appear after strip-out. Reserving 15–20% of the budget as contingency is critical to avoid stalling mid-project.
Frequently Asked Questions
- Must all plumbing be renewed in an old flat?
- If pipes are galvanised or 20+ years old, renewing is wisest; otherwise failures appear soon under your new finishes.
