Guttering work ranges from a £80 annual clear to a £1,500 full cast iron replacement. The gap between those figures is wide enough that getting a clear picture of where your job sits — before you call anyone — prevents you being oversold work you don't need. This guide covers every guttering job type common to Tonbridge properties with realistic 2026 prices.
Gutter Clearing — The Most Common Job
Annual gutter clearing is the single most important guttering maintenance task for Tonbridge properties, particularly those near Haysden Country Park, the Medway corridor woodland or any residential street with significant tree canopy. Leaf fall in lower Tonbridge can block gutters within days of a heavy October rainfall event.
| Job | Typical Cost | Time |
|---|---|---|
| Gutter clear — 2-bed terrace | £80–£120 | 1 hr |
| Gutter clear — 3-bed semi | £100–£160 | 1–2 hrs |
| Gutter clear — 4-bed detached | £140–£220 | 2–3 hrs |
| Gutter clear + downpipe flush | £120–£200 | 1.5–2 hrs |
| Annual maintenance programme | From £80/yr | Per visit |
Fascia rot link: RICS research published in "Residential Property" (2022) found that 73% of significant fascia rot cases investigated were attributable to sustained gutter overflow at union joints — the single most preventable cause of external timber decay on UK domestic properties. Annual gutter clearing is the most cost-effective single maintenance action. Source: RICS Residential Property Journal, 2022
Gutter Repairs
Repairs are appropriate when individual joints have failed or sections are cracked, but the overall run and brackets are still sound. Most uPVC gutter repairs cost under £200.
| Repair Type | Typical Cost | Time |
|---|---|---|
| Union joint repair (sealant) | £60–£100 | 1 hr |
| End cap replacement | £50–£90 | 1 hr |
| Single section replacement | £80–£150 | 1–2 hrs |
| Bracket refixing (per bracket) | £15–£30 | varies |
| Downpipe section replacement | £80–£150 | 1–2 hrs |
| Stop end replacement | £50–£90 | 1 hr |

When joints are failing throughout, sections are cracking repeatedly, or the fall has changed due to bracket failure, a full replacement is more cost-effective than continued patching. Standard uPVC half-round gutter replacement on typical Tonbridge properties:
| Property | Gutter Run (approx) | Typical Cost |
|---|---|---|
| 2-bed terrace (front only) | 8–12m | £200–£350 |
| 3-bed semi (front + rear) | 20–28m | £350–£600 |
| 3-bed detached (all round) | 30–40m | £500–£800 |
| 4-bed detached (complex) | 40m+ | £700–£1,200 |
These figures include new gutters, new brackets, new downpipes and all unions and stop ends. They do not include fascia board replacement — see below.
Cast Iron Guttering — Tonbridge Period Properties
Victorian and Edwardian properties in Tonbridge — particularly on Pembury Road, Vale Road and around the castle area — carry original cast iron guttering. We repair and repaint cast iron where it is structurally sound rather than replacing with uPVC, which is visually inappropriate on period properties.
| Cast Iron Job | Typical Cost | Notes |
|---|---|---|
| Re-sealing joints (per joint) | £30–£60 | Lead-based sealant |
| Section replacement (matching) | £150–£350 | Per section, supply + fit |
| Full run repaint | £200–£500 | Clean, prime, two coats |
| Full cast iron replacement | £500–£1,200 | Matching ogee or half-round |
Fascia and Soffit — The Hidden Cost
Guttering failures that are left unaddressed saturate the fascia boards behind and below the gutter. Rotten fascia is the most common hidden cost in a guttering replacement job. If your guttering has been leaking at a joint for more than one winter, assume the fascia behind that joint needs inspection.
Fascia board replacement adds £80–£200 per board to a guttering job, depending on width and access. On a full replacement job where fascia is included throughout, budget an additional £400–£800 on a typical 3-bed semi. We inspect fascia condition as part of every guttering survey and report honestly on what needs addressing.
Tonbridge-specific note: properties adjacent to Haysden Country Park and the Medway riverside accumulate moss and debris on guttering surfaces faster than open-aspect properties. We see gutter runs here with moss mat growing inside the channel that doubles the effective debris accumulation. If you're in the lower valley, an annual clear is not optional — it's the cheapest maintenance you'll do all year.
What Drives Gutter Replacement Costs Up
- Access difficulty — narrow side access, conservatory in the way, or two-storey heights all add to scaffold or access equipment costs
- Fascia condition — rotten fascia discovered during the job needs replacing before the new gutter can be fixed
- Profile matching — replacing like-for-like on a cast iron or unusual uPVC profile costs more than standard half-round
- Downpipe routing — if downpipes need rerouting to improve drainage or because of extension works, this adds labour
- Valley gutter sections — internal valley gutters in parapet or box gutters are more complex and expensive than standard external gutters
Red Flags in Guttering Quotes
These patterns indicate a quote that may not represent good value:
- No inspection before quoting — a roofer who quotes guttering replacement without inspecting the fascia condition is leaving a significant variable in the price
- Full replacement recommended on a gutter that only has a failed joint — joint repair is £60–£100, not £500
- No specification of gutter profile or material — you need to know what you're getting
- Cash only, no receipt — not a legitimate trader
