Genuine local coverage of Cardiff, CF3, CF5, CF10, CF11, CF14, CF15, CF23, CF24.
We cover every Cardiff postcode: CF3 (St Mellons, Rumney), CF5 (Canton, Ely, Fairwater), CF10 and CF11 (city centre, Cardiff Bay, Pontcanna, Grangetown), CF14 (Whitchurch, Llanishen, Rhiwbina), CF15 (Radyr, Taffs Well, Pentyrch), CF23 (Cyncoed, Pontprennau) and CF24 (Roath, Adamsdown, Cathays). All part of our core service area.
From our Newport yard we're inside Cardiff in under 30 minutes on the M4. Site surveys are booked within a week of enquiry, routinely sooner. There is no travel supplement or overnight cost on Cardiff quotes because we run the work as day trips.
Cardiff's housing is dominated by Victorian and Edwardian terraces in Pontcanna, Canton, Cathays and Roath; 1930s semis in Rhiwbina, Whitchurch and Heath; large detached properties in Cyncoed and Lisvane; and a heavy volume of modern development in the Bay, Pontprennau and along the Ely corridor. We work across all of them.
The most common carpentry work we take on in Cardiff is loft conversions and rear extensions on Victorian and Edwardian terraces, structural alterations for open-plan kitchen-diners in 1930s properties, roof replacements and dormers, and bespoke joinery, fitted alcove units, staircases and studies, for higher-value Cyncoed and Lisvane properties.
Every carpentry service we run, delivered in Cardiff.
One accountable team from survey to sign-off. Structural carpentry, roofing, extensions, joinery and full project management, all available across Cardiff and the wider South Wales area.

Newport-based means we're on-site in Cardiff faster than most Cardiff firms can cross the city. Snags and returns are same-day, not next-week.
Familiar with Cardiff conservation constraints
Pontcanna, Cathays and parts of Roath sit inside conservation areas with restrictions on roof profiles, dormers and joinery. We detail work to survive planning first time.

The specific problems Cardiff carpentry work throws up, and how we handle them.
Cardiff's Victorian and Edwardian terraces, huge stock across Pontcanna, Canton, Cathays and Roath, commonly have undersized joists, poorly detailed party walls and rear extensions bolted on over decades that have never been structurally rationalised. Any competent loft conversion or rear-extension in these areas has to unpick and re-detail this properly, not paint over it.
Cardiff shares the Severn Estuary exposure of Newport but with more urban wind-tunnel effects around tall Bay developments and Cardiff Central. Roofs specified without proper mechanical fixings and correctly-lapped underlays fail early. Timber cladding needs UV and moisture-tolerant detailing.
Access across Cardiff is genuinely difficult. Terraces off Cathedral Road and around Roath Park have zero on-street working space; Bay and Pontprennau new-builds have management-company rules restricting delivery times and skip use. Site logistics are planned into the quote.
Pre-war Cardiff housing typically lacks any meaningful insulation in the roof and cavity walls, uses undersized joinery, and has original single-glazed sashes that homeowners want to retain visually. Structural carpentry has to sit inside those constraints, deeper roof build-ups, engineered joists to cross-brace old walls, and joinery that reads as sympathetic to the original detail.

What working in Cardiff actually looks like.
The realities of South Wales carpentry, surveyed, priced and delivered honestly.
Cardiff carpentry work splits roughly into two worlds. In the older core, Pontcanna, Canton, Cathays, Roath, the job is nearly always retrofit. Undersized structure, tight access, conservation-area detailing and clients who want the finished result to feel like it was always there. In the newer suburbs, Pontprennau, Lisvane, parts of Radyr and the Bay, the work is closer to new-build: modern loadings, cleaner drawings, but stricter warranty and management-company oversight.
We treat both the same way. Site survey, drawings read end to end, fixed-price written quote, staged payments tied to milestones, and a written guarantee at handover. No day-rate creep, no sub-contractor chains, no surprises when the plasterer opens the ceiling up.
Cardiff clients tend to shop around carefully, which is a good thing. Our fixed quote sits on the table alongside two or three others; the reason clients pick us is not price alone but that the quote is line-by-line, the deposit is small, and the person who does the survey is the person who runs the job.
