A whole-house renovation is a planned refurbishment of an entire home, typically combining rewiring, heating, plastering, new kitchen and bathroom, flooring and decoration, and sometimes layout changes, carried out in a logical order under one project.
Whether you live in one of the larger towns, such as Redruth, Falmouth, St Austell and Truro, or somewhere quieter in Cornwall, the way we handle a whole-house renovation is identical. We survey, agree the specification with you, and confirm a fixed price on paper. Everything is planned under the regulations in force in England, and guide costs in the South West sit at £46,000–£122,000 with VAT.

Housing across Cornwall
Older Cornish homes are often built of granite or slatey local stone, with slate roofs and sometimes slate-hung walls facing the weather. Cob cottages survive in places, Truro and Falmouth keep Georgian and Victorian streets, and many towns have rendered post-war houses, bungalows and newer estates on their edges.
Stone and cob properties often need breathable lime render, careful repointing and roof repairs. Post-war and newer homes commonly benefit from new windows, roofline renewal, external rendering and single-storey extensions.
Cornwall faces Atlantic gales, driving rain and salt-laden air, so render, pointing and window hardware on exposed elevations need a suitably robust specification.
Planning and building rules in Cornwall
For anyone in Cornwall, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Survey and measure
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a whole-house renovation, and photograph or measure anything the quote needs to reflect.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Dates and permissions
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
The work itself
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Questions about a whole-house renovation in Cornwall
Which postcodes in Cornwall do you cover?
We cover TR15, TR11, PL25 and TR1, along with the rest of Cornwall. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Can you combine a whole-house renovation with other work?
Yes. Because we manage several trades under one contract, we can plan a whole-house renovation alongside other work on your Cornwall home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
What happens if you find damp or rot?
If we find damp or rot during a renovation, we stop that area, show you the problem and explain the likely cause, such as a leaking gutter, bridged damp-proof course or poor ventilation. We then give you a written price to fix the cause and repair the damage before carrying on. Treating the cause matters more than treating the symptom, so we focus on that first.
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
How long does a full house renovation take?
A full renovation of a typical 3-bed house usually takes around 8–16 weeks on site, and longer if there are structural changes or extensive repairs. A light refresh may take only a few weeks. Material lead times for kitchens, windows and bathroom fittings also affect the programme. We give you a week-by-week plan with your quote and update it as the work progresses.
