Guttering repair, replacement and cleaning across Portsmouth and Hampshire. Portsmouth's coastal humidity means moss grows faster in gutters here than in inland towns — blocked or failed gutters cause damp penetration quickly in this environment. We clean, repair and replace all guttering types from cast iron to modern UPVC.

📞 Call Now: 0239 307 1334Guttering in Portsmouth costs £80 to £2,000 for clearing, repair or full replacement. Coastal salt degrades UPVC joints faster than inland, so we check seals and falls on every visit. Cast iron matched on Victorian terraces. Free quote — call 0239 307 1334.
Portsmouth's island position — surrounded by the Solent, Portsmouth Harbour and Langstone Harbour — creates a microclimate with higher ambient humidity than mainland Hampshire towns. This directly affects guttering maintenance: moss and lichen establish and spread in gutters faster, joint seals degrade more quickly in the moisture-rich air, and the consequences of blockage are more immediate because Portsmouth receives significant annual rainfall with few extended dry periods.
The Victorian and Edwardian terraces of Southsea, Fratton and North End carry original cast iron guttering or its early replacement in 1960s UPVC — both now at or past end of life. The post-war estates carry UPVC of the same era as the roofs, 40 to 60 years old, with failed rubber seals and misaligned falls causing standing water rather than proper discharge. Misaligned falls — where bracket fixing has worked loose and the gutter no longer drains to the downpipe — are one of the most common causes of the overflow staining we see on Portsmouth properties.
We assess the full run including fall and downpipe condition. Written quote before any work starts.

Portsmouth's Victorian and Edwardian terraces in Fratton, North End, Southsea and Portsea carry original cast iron guttering that in many cases is over 100 years old and still functional. Cast iron guttering requires different maintenance than UPVC — annual cleaning, paint maintenance every 5 to 7 years to prevent internal rust, and joint inspection where the original lead-caulked joints may have dried and shrunk. A well-maintained cast iron system will outlast a UPVC replacement. A neglected one will rust through from the inside within 10 to 15 years. We maintain, repair and replace cast iron guttering across all Portsmouth postcodes and source the correct period profiles for Victorian properties where replacement is required.
UPVC gutter joint seals deteriorate faster in Portsmouth's salt air than in inland conditions. The rubber and mastic seals that keep UPVC gutter sections watertight are attacked by salt crystallisation — particularly at joints facing south-west into the prevailing sea air. Properties within 500 metres of the Solent or Portsmouth Harbour should have gutter joint integrity checked annually. A single failed UPVC joint running for a full season causes overflow that soaks the wall below — on Portsmouth's Victorian solid-wall terraces this reaches the interior wall face within two to three years if uncorrected.
"Gutters on our Fratton terrace were overflowing at every joint — hadn't been touched in years. Portsmouth Roofing cleared them, found two cracked sections and replaced the whole rear run. Job done in a morning."
"Cast iron replacement on our Victorian Southsea property. Sourced the correct ogee profile, fitted in a day. The gutters actually discharge properly for the first time in years."
"Overflowing gutters on our Cosham semi turned out to be a misaligned fall, not a blockage. Portsmouth Roofing re-fixed the brackets and sorted the fall in 90 minutes. Very fair — didn't charge for a full call-out."

Call 0239 307 1334Guttering trouble shows as water overflowing down the wall in rain, a visible sag in the gutter line, or damp appearing on the wall inside below roof level.
When it is not the answer: If the gutter is sound and only blocked, a clean and joint reseal solves it without replacement Read the full guide.
Solent salt air and exposed Channel weather corrode fixings and lift tiles faster than inland Hampshire. Portsea Island's dense Victorian terraces mean rear elevations are often reached only through tight alleys, and front scaffold needs permit-controlled pavement space. It is why we specify marine-grade fixings and correct lead codes as standard on Portsmouth roofs — the coastal environment punishes anything less.
We check falls, joints and fixings along the whole run and identify whether cleaning, repair or replacement is needed.
An itemised quote for the work, with coastal-grade uPVC or matched cast iron specified as appropriate.
We book the work and arrange tower or scaffold access where height requires it.
We renew or repair the guttering with correctly calculated falls, sealing joints against coastal salt degradation.
We test the run with water, clear debris and issue the workmanship guarantee.
| Job | Typical duration |
|---|---|
| Gutter clean and reseal | 2–3 hours |
| Section replacement | Half a day |
| Full house guttering | 1 day |
| Cast iron repair (Victorian) | Half to full day |
| Downpipe renewal | 2–3 hours |
Heavy rain makes gutter falls impossible to set accurately — we reschedule wet days rather than guess.
Guttering works from towers or ladders on most homes; two-storey and terrace runs may need a short scaffold. Scaffold is specified for: two-storey runs, terrace frontages over pavements, and where safe standing time is needed - always itemised in your written quote, never a hidden extra, and we arrange it.
Portsea Island's dense Victorian terraces mean rear elevations are often reached only through tight alleys, and front scaffold needs permit-controlled pavement space. Pavement scaffold and skip permits go through Portsmouth City Council; allow a few working days on streets like Albert Road, Fawcett Road, Marmion Road where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Gutter clean & reseal | £80–£150 | Twice-yearly coastal |
| Section replacement | £25–£45/m | Coastal-grade uPVC |
| Full house guttering | £400–£900 | Correct falls |
| Cast iron repair | £120–£350 | Victorian like-for-like |
| Downpipe renewal | £90–£220 | Per run |

No deposit on repairs under £500. Staged payments on re-roofs — nothing up front before materials are on site. All prices include VAT; written itemised quote before any work.
Covering PO1, PO2, PO3, PO4, PO5, PO6 and surrounding postcodes.
Guttering workmanship is guaranteed for 10 years; the uPVC or cast iron carries its own manufacturer warranty on top.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
A few hours to a day of external ladder or scaffold work, no internal disruption — we clear all old guttering and debris away. You do not need to stay home for external work - we just need power and access agreed in advance.
We fit guttering year-round, though we set falls on dry days so water tests are accurate. Solent salt air and exposed Channel weather corrode fixings and lift tiles faster than inland Hampshire.
Full UPVC guttering on a standard Portsmouth semi: £400 to £750. Cast iron replacement: £800 to £2,000 depending on property size and profile. Section replacement from £120. Free written quotes.
At least once a year in November after leaf fall. Properties near harbour-facing streets or with heavy tree cover benefit from twice-yearly clearing — Portsmouth's coastal humidity accelerates moss growth in gutters significantly.
Yes — we replace like-for-like in cast iron where required. For conservation area properties we advise on what is expected before quoting. Cast-iron-effect UPVC is available where cast iron is not required.
The harbour and Solent microclimate creates higher ambient humidity across Portsea Island, which accelerates moss and lichen growth in gutters compared to inland Hampshire towns. Moss-blocked gutters overflow quickly in Portsmouth's significant annual rainfall.
Yes — all of Portsmouth including Southsea, Fratton, Cosham, North End and Paulsgrove, plus Fareham, Gosport, Havant and surrounding areas.
