Installer replacing a full run of white uPVC guttering on a detached UK house

Guttering: repairs and full replacement

Leaking joints fixed and whole systems replaced by vetted local installers. Get up to three free quotes in 60 seconds.

Quick answer: guttering work runs from an £80 – £250 joint repair to full replacement at £600 – £1,200 for a typical semi-detached house in 2026, supplied and fitted in standard uPVC. New uPVC guttering costs £30 – £60 per metre.

Guttering repairs and replacement keep rainwater off your walls and out of your home. Every drop that lands on the roof has to travel through the gutters, and when they fail the water goes straight into the brickwork instead. Guttering is cheap compared with what it protects, which is exactly why it should be fixed the week it starts dripping, not the year the damp appears.

What our guttering service covers

  • Repairs: leaking joints, failed brackets, sagging runs re-set to the correct fall, and individual downpipes replaced.
  • Full replacement: the old system stripped and a new one fitted in uPVC, aluminium or cast iron, with the fall set properly along every run.
  • Downpipes and drainage: new downpipes routed to gullies so the water actually leaves the building line.
  • Cleaning: if the system is sound and just blocked, a professional gutter clean is all you need, and it is the cheapest job on the list.

When repairs stop making sense

One dripping union or one slipped bracket is a repair. But uPVC goes brittle and chalky with age, and once several joints weep or the runs have lost their fall so water pools instead of draining, you are paying for the same repairs every winter. Watch for the classic signs of a failed system: green algae streaks down the brickwork, plants growing in the gutter, peeling paint or rot on the fascias, and a damp patch creeping across an upstairs ceiling. That last one is one of the most misdiagnosed "roof leaks" in the UK; our guide to damp patches on ceilings explains how to tell the difference before you pay for roof work you do not need.

How a replacement runs

A full replacement is usually a one-day job on a semi, done from ladders or an access tower. The installer strips the old runs and brackets, checks the fascia boards the new brackets will fix into, then fits the new system with a consistent fall towards the downpipes and tests it with water before leaving. If the fascias are soft or rotten they need dealing with first, because new guttering hung on failing boards will not stay up; see our fascia and soffit service for how the two jobs combine.

What guttering costs

These are the 2026 rates from our guttering cost guide, which also compares uPVC, aluminium and cast iron in detail:

JobTypical cost (2026)
Gutter cleaning (whole house)£80 – £200
Repair leaking joint or bracket£80 – £250
Replace a downpipe (each)£80 – £150
New uPVC guttering per metre (supplied & fitted)£30 – £60
Whole semi-detached replacement£600 – £1,200
Whole detached replacement£900 – £1,800
Tip: gutters and fascias share the same access and the gutter brackets screw into the fascia board, so if your fascias are tired too, price the combined job. One visit costs meaningfully less than two, and the new system goes onto sound boards.

Why use a vetted installer

Guttering looks simple, and badly fitted guttering proves it is not: runs set without enough fall, brackets spaced too far apart and joints forced together all work loose within a couple of winters. Every installer we refer is vetted for insurance, trading history and the quality of recent work, and you can check their quotes against the fair rates above.

Guttering FAQs

Guttering questions, answered

Replacing all the guttering on a typical UK semi-detached house costs £600 to £1,200 in 2026 in standard uPVC, supplied and fitted, including removal of the old run. A detached house runs £900 to £1,800, and new uPVC guttering costs £30 to £60 per metre fitted. Full breakdown in the guttering cost guide.
Often, yes. A leaking joint or failed bracket is an £80 to £250 repair, and a single downpipe £80 to £150, provided a matching profile is still available. Replacement wins when the plastic has gone brittle, multiple joints leak, or the runs have lost their fall so water pools instead of draining.
uPVC is the standard choice: the cheapest at £30 to £60 per metre fitted, low-maintenance and good for 20 to 30 years. Aluminium and cast iron cost two to three times more but suit period properties and last for decades; cast iron needs periodic repainting to stay rust-free.
Yes. When guttering fails, rainwater sheets over the edge and soaks the wall below, and the damp patch that follows on an inside wall or ceiling is one of the most commonly misdiagnosed roof leaks. Rule the gutters out first; our damp patch guide shows how.
Often it makes sense. Gutter brackets screw into the fascia board, so the gutters come off during a fascia job anyway, and both jobs share the same access. If your fascias are tired too, pricing the combined job through our fascia and soffit service usually beats two separate visits.
