"Combi swap in a mill terrace, needed the gas run upsized and re-routed. Boxing looks tidier than the original install. £50 diagnostic came off the bill."

In short
Blackburn stone-terrace bathrooms hide the same three surprises — Victorian lead soil-stacks, 130-year-old joists, and stone-flag floors that need levelling before any tile can go down.
Blackburn bathroom work is dominated by stone-terrace refits in BB2/BB3 (lead stack replacement, joist doubling, floor levelling), newer-estate refits in BB1, and walk-in shower conversions in Wilpshire and Mellor semis.
BB2/BB3 stone terraces: 1.7m × 2.0m compact. BB1 newer estates: 2.2m × 2.6m. Wilpshire / Mellor semis: 2.4m × 2.8m.
Every quote includes a scale drawing before you sign — so you can see exactly what fits, what doesn't, and where the walk-in shower actually opens.
City Plumbing Blackburn (Bolton Road), Plumb Center Darwen, Wolseley Blackburn and Selco Blackburn for boards.
Every quote lists the merchant, the manufacturer and the model — no mystery-branded fittings, no invoice-only prices. You can walk into the same trade counter and cross-check the price.
10–14 working days for a stone-terrace refit; 10–13 for a BB1 newer-estate refit; 12–15 for a Wilpshire semi.
We publish the working-day count because the tanking cure (48h) and tile grout cure (24h) are physics, not fitter speed — skipping them causes leaks and popped tiles 6 months later.
£4,400–£6,600 for a stone-terrace refit; £5,800–£8,500 for a BB1 newer-estate refit; £7,000–£10,500 for a Wilpshire semi.
Every price is confirmed in writing after the £50 diagnostic — itemised for fixtures, tanking, waste, extraction and tiling. Nothing billable starts until you approve the fair fixed quote, and the £50 is refunded if we can't reasonably scope the job.
A Blackburn pattern is discovering a lead soil-stack mid-strip-out and quoting a £2,500 change-order. An honest surveyor spots this before demolition.
Our promise on every Blackburn bathroom-fit call-out: £50 to attend, survey and scope; an itemised written quote before any billable work; and 12 months guarantee on workmanship after completion.

"Airing-cupboard cylinder was rumbling and losing pressure. Diagnosed a failing coil, replaced the cylinder and re-commissioned the whole system properly."
