Costs, at cost
Every invoice from Frodsham merchants and sub-contractors is passed straight to you, exactly as we pay it. No mark-up buried in materials, no mystery line items, nothing to negotiate over.
Builders in Frodsham
Extensions, whole-house renovations and self-builds across Frodsham, Helsby and the sandstone ridge on an open book. Every invoice visible, a fixed management fee, a fair 10% on top — typically around 11% less than a padded fixed-price quote.
Clarity in Simplicity
Why we're different
Frodsham sits tucked below the sandstone ridge on the north Cheshire edge and has one of the more distinctive housing profiles in the county. Main Street is a well-preserved run of Victorian and Georgian frontages. Above the town, the slopes of Overton Hill hold a heavy concentration of substantial family homes with proper views. Below, the villages of Helsby, Kingsley, Norley and Manley add solid period cottages, sandstone farmhouses and modern estates. Frodsham projects are typically mid-size renovations and extensions where owners have bought a well-located house that needs work to unlock its potential.
Built Clear runs Frodsham projects on an open book. We price your build from the plans, pass every invoice through at cost, add one fixed management fee agreed at the start, and a flat 10% on top for overheads and profit. Open-book pricing gives Frodsham clients the confidence to spend properly on the parts that matter — a proper kitchen extension, structural steels done right, a real roof — and hold back on the parts that don't.
On a typical Frodsham job that comes out around 11% below a conventional fixed-price quote. See our wider Cheshire builders page for how the model plays out across the rest of the county, or our 2026 Cheshire cost guide for real per-square-metre rates.
The Open-Book Model
Every invoice from Frodsham merchants and sub-contractors is passed straight to you, exactly as we pay it. No mark-up buried in materials, no mystery line items, nothing to negotiate over.
One agreed, fixed fee to run the whole project. Programmed, coordinated, delivered. Set at the start, doesn't move as the job progresses.
A simple ten percent on real costs covers overheads and profit. No 15% loading, no padded contingencies. Sustainable for us, fair for you.
The result: typically around 11% less than a conventional fixed-price Frodsham estimate, and a build where everyone stays on the same side.
What we build
Rear extensions, side returns, wraparounds and orangeries. Frodsham hillside plots often mean split-level extension design and structural work to open up rear elevations to the view. Priced from your drawings and managed transparently.
Full refurbishment. Rewires, replumbs, replasters, structural openings, new roofs, insulation upgrades. Frodsham Victorian and Edwardian stock rewards proper investment rather than surface tidying.
The countryside around Kingsley, Norley, Manley and Alvanley has fine agricultural conversion stock. Structural, thermal, off-grid services, joinery, finishes. Complex work suits open-book pricing best.
One-off new builds on hillside plots around Frodsham and the sandstone ridge, project-managed from planning through to handover with a fully transparent cost report at every stage.
Adding usable space to Frodsham family homes without adding footprint. Dormer lofts, hip-to-gables, integral garage conversions.
Full strip-out and refit, often as part of a wider ground-floor reconfiguration. You see the true cost of every unit, every appliance, every tile, every fitting.
Where we work
Alongside Frodsham itself we cover Helsby, Kingsley, Norley, Manley, Alvanley, Overton, Newton, Aston, Dutton and the surrounding villages. From our base in Rossett we can be on a Frodsham site within 30 to 40 minutes. See our full Cheshire coverage for the wider county, or our Chester builders page if you're closer to the city.
Real words from real projects
Ben and his team were meticulous in planning and really clear in their communications throughout. From start to finish, the project ran seamlessly and was actually delivered earlier than anticipated. After this positive experience, we're booking for a further renovation and extension project with Built Clear in the next six months.

Common questions
Frodsham projects generally sit at £1,950 to £2,800 per square metre for extensions and renovations, and £2,250 to £3,150 per square metre for new builds. Hillside plots with retaining or split-level structural work can land at the top of the range. On open-book pricing you see the exact merchant and sub-contractor numbers rather than a single padded figure. See the 2026 Cheshire cost guide for detail by project type.
A single-storey rear extension typically takes 12 to 20 weeks on site. A two-storey side extension is 20 to 28 weeks. A whole-house renovation runs 6 to 12 months. A barn conversion or self-build is 10 to 18 months from foundations to handover. The programme is agreed alongside the fixed management fee at the start.
Yes. A significant proportion of Frodsham housing sits on the slopes of Overton Hill and Frodsham Hill, which brings retaining, drainage and split-level structural questions that a lot of builders are wary of. We're happy to price and manage that work — and open-book pricing suits it particularly well because the unknowns get resolved in front of you rather than padded into a fixed price.
Not in the traditional sense. On projects over £80,000, a fixed-price quote has to include a risk premium against the unknown, and that padding is what makes fixed-price quotes look steep. Open-book pricing hands the saving back to you: real costs at cost, a flat 10% on top, and a fixed management fee agreed at the start.
Yes. Helsby sits directly next door to Frodsham on the sandstone ridge and shares much of the same housing character. Kingsley, Norley and Manley are all comfortable ground for us — extensions, renovations and the occasional barn conversion. Same open-book model, same fixed management fee, same flat 10%.
