St Austell Homeowners Trust BestBuilders
Loft dormer en-suite in St Austell, South West. Bath plus separate shower in a small footprint by reconfiguring the door swing. Worked out at £11280 over 12 days. Insurance copy of the test certificate arrived without me having to chase. Tile grout still bright white after a winter of use.
Used BestBuilders to find a bathroom fitter near St Austell. Three responses, all from fitters within 5 miles of St Austell, mid-tier option, but they brought a tile sample to the survey. Fitter found a hidden split in the soil pipe - flagged it, fixed for £180, no surprise invoice. Estate agent valued the work at +£12k of property uplift.
Five months later, the low-profile shower tray feels safer for the kids than the old stepped one. Replaced one floor tile that had a manufacturing flaw - no quibble at all. Booked them in for the loft en-suite next year already.
