Why fascias, soffits and guttering go together in Old Isleworth
On most TW7 homes the fascia board, soffit panel and gutter are one continuous system at the eaves. If the timber facias have rotted, water has almost certainly tracked behind the gutter brackets and into the soffit, and the gutter brackets themselves are usually loose. Replacing just the fascia leaves you with a new board screwed to compromised brackets and an old gutter that won't seal at the joints — which is why we quote the three together and refuse single-component patch jobs unless the rest is genuinely sound.
Period townhouses around Church Street and the All Saints riverside in Old Isleworth typically run Georgian and Victorian riverside core. That matters because the original eaves timber on anything pre-1980 is usually softwood with no preservative treatment — once it's started to fail at one corner it's normally gone right around the building. We measure every run, photograph the back of the fascia where rot tends to start, and quote on what's actually there rather than averaging it out.
What's included in a Old Isleworth fascia replacement
Survey and measure
On-site measure of every eaves run, every gable, every bay. We check soffit depth, rafter feet condition, and existing gutter sizing — TW, KT and SW houses vary far more than they look.
Strip old fascias, soffits and guttering
Scaffold up, gutters drained and removed, soffit panels pulled, fascia boards lifted. Rotten rafter feet are cut back and new treated timber sistered on before the new fascia goes anywhere near it.
New uPVC fascias and soffits
Full 18mm or 25mm uPVC fascia board (with 9mm vented or solid uPVC soffit) in your chosen colour, mechanically fixed every 600mm into sound timber — never just nailed to the old board.
All-new gutters and downpipes
112mm half-round or 114mm square uPVC gutters at the correct fall (1:600 minimum), new brackets every 800mm, full-length downpipes back into existing or new gullies. Pressure-tested before sign-off.

Frequently asked questions
How much does a full fascia replacement cost in Old Isleworth?
A typical 3-bed semi in TW7 is usually £1,800–£3,200 for full fascias, soffits and guttering — depending on eaves length, whether the original timbers are rotten and need rebuilding, and whether you choose white or a coloured/woodgrain uPVC. We quote on-site after measuring, not from photos.
Do you replace facias, soffits and guttering as one job in Old Isleworth?
Yes — and it's almost always cheaper to do all three together. The scaffolding goes up once, the eaves are exposed once, and you get a fully sealed eaves detail rather than mixing old and new components. We rarely recommend a fascia-only job unless the soffits and gutters are genuinely recent.
How long does fascias replacement take on a Old Isleworth house?
A semi-detached or terrace is normally a 2–3 day job, a detached takes 3–5 days. Scaffolding stays up for the duration. We arrive each morning and tidy down each evening — no skip on the road overnight unless agreed.
Do I need scaffolding for fascia replacement in TW7?
For anything above single-storey eaves, yes — towers and ladders aren't safe for the volume of cutting and lifting involved. Scaffolding is included in our quote and erected by a CISRS-trained team.
What's included when you renew the gutters?
New 112mm half-round or 114mm square-line uPVC gutters, all new brackets at correct fall, new round or square downpipes connected back into existing gullies, plus leaf guards on request. We pressure-test every run before leaving site.
Can I have black or coloured fascias instead of white?
Yes — anthracite grey, black, rosewood and golden oak are all in stock with our suppliers and add about 10–15% to a white quote. We bring sample boards to the survey so you can see them against your brickwork.
In summary
Full fascias, soffits and guttering replacement in Old Isleworth (TW7) by a family-run, fully-insured local team. Honest measure, no high-pressure quote, scaffolding included, finished in 2–5 days with a 10-year workmanship guarantee.
