When to Repair vs Replace: A Complete Guide

The Repair or Replace Dilemma

Every homeowner faces this question: is it worth repairing, or should I just replace it? The answer depends on several factors including cost, age, safety, and efficiency.

The 50% Rule

A good general rule: if the repair cost exceeds 50% of the replacement cost, it's usually better to replace. But consider the item's age and expected remaining lifespan too.

Windows & Doors

Repair if: Single broken pane, minor draughts fixable with new seals, cosmetic damage only.

Replace if: Frames are rotting, double glazing has failed (condensation between panes), they're single-glazed, or over 20 years old.

Boiler & Heating

Repair if: Under 10 years old, minor fault, parts readily available.

Replace if: Over 15 years old, frequent breakdowns, efficiency rating below C, using R22 refrigerant.

Roofing

Repair if: A few missing or damaged tiles, localised leak, flashing needs resealing.

Replace if: Widespread damage, sagging roof deck, multiple leaks, tiles approaching end of life (30-50 years).

Flooring

Repair if: Scratches can be sanded and refinished, single damaged section, subfloor is sound.

Replace if: Water damage, extensive wear, subfloor issues, or it's cheaper than professional restoration.

Plumbing

Repair if: Isolated leak, single fixture issue, pipes in good general condition.

Replace if: Lead pipes, widespread corrosion, frequent leaks, or during a major renovation.
