Gutter Replacement UK: When to Repair vs Replace

Do Not Ignore Your Gutters

Gutters are the unsung heroes of your home. They channel thousands of litres of rainwater away from your walls and foundations every year. When they fail, the consequences can be expensive — damp walls, stained render, and even foundation damage.

When to Repair

If only one or two sections are leaking at the joints, a simple reseal or bracket replacement is usually sufficient. Cost: £50-£150 for a roofer to attend and fix.

When to Replace

If your gutters are sagging, cracked in multiple places, or made of old cast iron that has corroded, a full replacement is more cost-effective. A full set of uPVC gutters for a semi-detached house costs £400-£900 installed.

Material Options

• uPVC: The UK standard. Cheap, light, easy to install.
• Aluminium: Longer lasting, sleeker look. 2-3x the price of uPVC.
• Cast Iron: Traditional. Best for period properties. Expensive and heavy.
