Cornwall's capital is a city of Georgian townhouses, granite-fronted cottages and converted chapels — handsome buildings with solid stone walls and a famously damp climate. RPG Carpentry & Joinery supplies and fits solid and engineered oak flooring across Truro, Falmouth, Penryn and beyond, with the damp-proofing and acclimatisation Cornish properties demand.
Truro sits at the head of its river as Cornwall's administrative and cathedral city, surrounded by some of the county's finest period housing. Georgian townhouses line its older streets, granite-fronted cottages cluster through the centre, and converted chapels make characterful homes here and in Falmouth, Penryn, Redruth and Probus. What these buildings share is solid stone construction and exposure to Cornwall's damp, mild climate — the two factors that shape every oak floor we lay across the TR postcodes.
From a formal Georgian drawing room to a snug granite cottage or a dramatic chapel conversion, we match the oak, the grade and — crucially — the damp-proofing to the property, so the finished floor is as durable as it is beautiful.
Engineered oak is our default recommendation across Cornwall. Its genuine oak wear layer sits on a cross-bonded plywood core that resists the moisture movement that catches out solid timber in a damp granite cottage or a ground-floor chapel conversion. It also works well over the underfloor heating common in Cornish renovations.
Solid oak remains a lovely option for a dry, well-ventilated first-floor room in a Truro townhouse, and it can be sanded back many times. Near solid stone walls and on the ground floor, though, its greater movement makes engineered the safer call. On grade, prime boards give a refined look for a Georgian interior, while rustic grade suits the character of a granite cottage or chapel.
In Cornwall, damp is the deciding factor. Truro's granite cottages and converted chapels typically have solid stone walls with little or no original damp-proofing, and the county's mild, wet climate keeps ground moisture high. Lay oak over that without protection and the floor will pay the price. Before any board goes down we measure the moisture content of the subfloor, identify damp ingress, and fit a suitable damp-proof membrane where the readings demand it — while taking care not to trap moisture in walls that need to breathe.
Acclimatisation matters more here than almost anywhere. We leave the oak in the room for several days, often longer than we would inland, so its moisture content settles to the property's true conditions before fitting, and we leave a generous expansion gap around the perimeter. This patient preparation is what keeps a Cornish oak floor flat and gap-free for years.
Oak flooring is priced per square metre, supplied and fitted. The figures below are a 2026 guide for Truro and Cornwall; your final quote depends on board choice, subfloor condition and damp work required.
| Option | Price (supplied & fitted) | Notes |
|---|---|---|
| Engineered oak, prime grade | £45 – £65/m² | Safest choice for damp granite cottages & ground floors |
| Solid oak, prime grade | £60 – £80/m² | Dry first-floor rooms in Georgian townhouses |
| Wide-plank / character grade | £75 – £90/m² | Characterful boards for cottages & chapel conversions |
| Damp-proofing & subfloor prep | Quoted separately | Moisture testing, DPM, levelling as required |
Cornwall's damp climate and solid stone walls are exactly the conditions that ruin oak floors fitted without proper preparation. We know them well. We have laid oak across Truro's Georgian townhouses, granite cottages and chapel conversions, and we treat moisture testing, damp-proofing and patient acclimatisation as the heart of the job rather than an afterthought. With more than 200 projects behind us, we get the groundwork right so the floor lasts.
Every quote is free, written and itemised, and we are happy to bring board samples to your Truro home so you can judge the grade and finish against your own stone and light before committing.
Truro and much of Cornwall has a damp climate and many homes have solid granite or stone walls with limited damp-proofing. Without a proper moisture barrier and good moisture readings, that dampness can travel into an oak floor and cause cupping or lifting. On Cornish properties we treat damp-proofing and moisture testing as essential, not optional.
Oak flooring in Truro costs around £45 to £90 per m² supplied and fitted in 2026. Engineered prime grade is the most affordable and the safest bet in damp Cornish properties, with solid oak and wide-plank character boards above it. Damp remediation and a damp-proof membrane are quoted separately once we have surveyed the floor.
Usually, yes. Granite-fronted cottages in Truro, Falmouth and Penryn often have solid walls and damper conditions, and engineered oak's cross-bonded core copes with that far better than solid timber. Solid oak can still work in a dry, well-ventilated upper room, but engineered is the more dependable choice on the ground floor.
Cornwall's damp, mild climate means indoor moisture levels can be higher than the timber arrives at. We leave the oak in the room for several days, often longer than inland, so it settles to the property's real conditions before fitting. In period stone homes this acclimatisation step is critical to prevent gaps and movement later.
