We specify coastal-grade UPVC on all Cosham fascia work.
Fascia and guttering are always assessed together in Cosham. A rotten fascia cannot support guttering — and fitting new guttering to a failing fascia wastes the investment. Both are assessed as part of every survey.
Correct soffit ventilation prevents condensation in the roof void — a concern in Cosham's Portsea Island coastal microclimate which creates elevated ambient humidity. We specify correctly sized vents on all soffit replacement work.
| Service | Cost | Notes |
|---|---|---|
| Full fascia and soffit replacement (semi) | 800-1400 | Both elevations UPVC |
| Single elevation | 400-750 | Includes guttering assessment |
| Rotten section repair | 150-350 | Per elevation |
| Soffit vent inserts | 150-300 | Correct sizing |
"Fascia replacement on our 1930s semi — the 1980s UPVC had finally given up. New run fitted with correctly calculated fall angles."
"1930s semi on Drayton Lane — re-roof, Portsmouth Roofing was honest that the tiles were past repair. Specified the correct modern equivalent."
"Nail sickness on our post-war Cosham property — both slopes assessed and re-fixed with stainless. Explained exactly what to watch for."
Guttering 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.
Portsdown Hill shelter reduces salt slightly, but 1930s concrete tiles here are shedding surface aggregate at 85–90 years old. Cosham's 1930s semis have generous simple roofs with good access, though mature avenue trees complicate scaffold and skip placement. It is why we specify marine-grade fixings and correct lead codes as standard on Cosham 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.
Cosham's 1930s semis have generous simple roofs with good access, though mature avenue trees complicate scaffold and skip placement. Pavement scaffold and skip permits go through Portsmouth City Council; allow a few working days on streets like High Street, Wootton Street, Spur Road where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Slipped or cracked tiles | £150–£350 | Per visit incl. access |
| Leak diagnosis & repair | £150–£500 | Depends on water travel |
| Chimney flashing | £200–£600 | Code 5–6 lead |
| Valley repair | £400–£900 | Strip and re-lay |

We fit guttering year-round, though we set falls on dry days so water tests are accurate. Portsdown Hill shelter reduces salt slightly, but 1930s concrete tiles here are shedding surface aggregate at 85–90 years old.
Signs include visible rot or softness when pressed, paint peeling, guttering pulling away, or brown staining behind the gutterline.

Cosham sits at the northern approach to Portsea Island — slightly inland from the harbour but within the island's salt-influenced microclimate. Frost incidence is similar to Portsmouth generally but the 1930s semi concentration creates a specific repair profile across the suburb.
Cosham and adjacent Drayton are dominated by 1930s semi-detached properties — original concrete plain tiles now 85 to 90 years old and showing advanced surface aggregate erosion. Many properties are at or past the repair vs replace decision point.
Cosham's 1930s semis typically had their fascia replaced in the 1980s and 90s in UPVC — now 30 to 40 years old and showing failed joints and misaligned falls that cause guttering to overflow onto the original brickwork. Every job we carry out in Cosham is specified for these specific conditions — not a generic Portsmouth-wide approach.
