Fascia boards, soffits and bargeboards form the roofline of your property — they support guttering, seal the roof void, and provide essential ventilation. When they rot, warp or crack, water gets into Serving Isleworth and all surrounding areas in Hounslow.
Fascia boards, soffits and bargeboards form the roofline of your property — they support guttering, seal the roof void, and provide essential ventilation. When they rot, warp or crack, water gets into the roof space and your guttering loses its support. We strip failed roofline back to sound timber and install new fascia, soffit and bargeboard in uPVC or treated timber.
Peeling paint, soft or spongy boards, visible gaps between fascia and wall, wasp or bird nests in the soffit, sagging gutters — these all indicate roofline failure. In Isleworth, the most common cause is decades of blocked gutters driving water into fascia boards.
uPVC is maintenance-free, rot-proof and available in a range of colours. Timber gives a traditional appearance and is required in some conservation areas. For most Isleworth properties, uPVC is the practical choice — it eliminates the repainting cycle and lasts 20-30 years.
Adequate roof void ventilation prevents condensation that rots timbers from the inside. We install ventilated soffits as standard on every roofline replacement in Isleworth — continuous soffit vent strip provides the 10mm equivalent ventilation gap required by Building Regulations.
Old Isleworth near the Thames has Georgian and Victorian riverside properties. 1930s semis along Twickenham Road. Post-war estates near Osterley. The conservation area around Church Street contains listed buildings with strict material requirements. For fascia & soffits work in Isleworth, this housing profile means we commonly encounter Thames riverside damp penetration on Old Isleworth period properties — ground-floor flooding drives moisture upward into roof timbers. Lead flashing failure on Church Street conservation properties. C
The streets of Isleworth — including Church Street Isleworth, Twickenham Road, London Road Isleworth — have roofing characteristics that reflect their construction era and the specific exposure conditions of Hounslow. Hounslow's proximity to the Thames creates localised humidity issues, particularly in Chiswick, Brentford and Isleworth where riverside properties face accelerated moss growth and lead oxidation. The

A full roofline replacement on a typical Isleworth semi costs £1,500–£2,500 in uPVC. Larger detached properties run £2,500–£3,500. Timber replacement for period properties is 30-50% more.
Quality uPVC fascia boards last 20-30 years with no maintenance. Cheaper products may discolour or warp within 10-15 years. We use only established manufacturer products with a minimum 10-year colour guarantee.
Technically yes, but we strongly recommend replacing guttering at the same time. The scaffold is already up, and old gutter fixings often damage new fascia boards during reinstallation.
Not in most cases. However, if your Isleworth property is in a conservation area, you may need to match existing materials and profiles. We advise on planning requirements as part of our quotation.
The primary cause is blocked or leaking gutters — water overflows onto the fascia board and soaks in over time. Once rot starts, it spreads along the grain and eventually compromises the gutter mounting points.
If the boards are sound with only surface weathering, painting can extend their life by 5-10 years. If there is any rot, softness, or warping, replacement is the only effective solution.
Yes — ventilated soffit strips are included as standard on every roofline replacement. This provides essential roof void ventilation that prevents condensation and timber rot.
Hounslow's roofing story is shaped by two forces: the Thames and Heathrow. Riverside properties in Chiswick, Brentford and Isleworth have roofing challenges driven by humidity, flood risk and the specific material requirements of their conservation areas. Properties further west in Hounslow, Heston and Feltham face the unique environmental stress of the Heathrow flight path — sustained low-frequency vibration from aircraft on approach that gradually loosens mortar joints and ridge fixings.
The Thames corridor through Hounslow creates a microclimate that makes seasonal roof maintenance essential. Winter humidity promotes moss and algae growth that is noticeably worse on north-facing pitches near the river than on equivalent roofs just a mile inland. Autumn gutter clearance is critical — the mature plane trees along Chiswick High Road, Strand-on-the-Green and Brentford High Street produce enormous volumes of leaf debris that can block an entire gutter run in a single week.
Chiswick and Brentford have seen significant property price growth, with many Victorian and Edwardian houses now valued above £1 million. In conservation areas covering much of Chiswick and Old Isleworth, roofing materials must match originals — a requirement that adds 30-60% to costs but protects both the streetscape and your property's premium value.
Every job follows our standard quality process: free inspection and assessment, written quote with full scope of work, professional installation by our own team using specified materials, post-completion inspection with photographic record, and a written guarantee. This process applies to every job regardless of size — a £200 repair gets the same professional approach as a £15,000 re-roof.
We specify materials based on the specific conditions of your property — its age, construction type, exposure and the performance requirements of the job. We never use the cheapest available option as default — we use the right option for your situation and explain why. All materials are sourced from established manufacturers with proven track records.
All work carries our written workmanship guarantee. The guarantee period depends on the scope of work — from 2 years on minor repairs to 10 years on full installations. Guarantees are transferable if you sell the property. Materials carry the manufacturer's own guarantee in addition to our workmanship cover.

Scaffold or ladder by height. Scaffold is specified for: two-storey, full perimeter - always itemised in your written quote, never a hidden extra, and we arrange it.
Georgian to modern mixed stock — access and scaffold requirements vary by street. Pavement scaffold and skip permits go through Hounslow Council; allow a few working days on streets like London Road, Linkfield Road where space is tight.
