Your gutters are dripping, sagging, or pulling away from the fascia. The question most homeowners ask next is the wrong one: "How much will this cost?" The right question is: "Do I need a repair, or am I about to pay for the same problem twice?" Repair is quicker and cheaper in the short term. But if the underlying system is failing, patching it is money thrown at a problem that will return.
5 Signs You Can Repair Your Gutters
These situations are generally fixable without full replacement:
- Single leaking joint. Joints fail when the rubber seal dries out. A professional can reseal or replace the union in under an hour. Cost: £60-£90.
- Gutter pulling away from the fascia. If the fascia board is sound, this is a bracket failure. New fixings and re-alignment costs £80-£150.
- Minor crack or hole in one section. A small crack can be patched or a short replacement section fitted. Cost: £100-£200.
- Blocked or slow-draining gutter. If the pitch has shifted slightly, adjusting the bracket height restores the correct 1:600 fall.
- One sagging section. Sagging caused by bracket failure, not material deformation, can be corrected by re-hanging that section.
6 Signs You Need Gutter Replacement
Some problems cannot be patched away:
- Leaks in three or more locations. Multiple failure points mean the guttering is degrading generally, not at isolated weak spots.
- Widespread rust or corrosion. Surface rust on cast iron is treatable. But if rust has eaten through the material in multiple places, the structure is compromised.
- Persistent sagging along entire runs. Sagging along the full length means the gutter material itself has warped. No bracket can fix that.
- System is 20+ years old (uPVC). At that age, joint seals, material strength, and bracket fixings are all approaching end of life simultaneously.
- Visible cracks in the gutter body. Hairline cracks widen with freeze-thaw cycles. A crack visible in summer is a split by February.
- Damp patches on interior walls below the roofline. The gutter system has been failing long enough to cause secondary damage.
