Washington Homeowners Trust BestBuilders
Wet room conversion in Washington, North East. Tanked the wet area properly, large-format porcelain tiles, frameless glass screen. Came in £520 under quote thanks to a simpler waste route. Sub-trades all coordinated through the lead fitter, never had to make a phone call. Site spotless every evening, never an inconvenience.
Used BestBuilders to find a bathroom fitter near Washington. Got two solid quotes back within a day, went with the highest-rated reviewer rather than the cheapest quote. Day-end photographs of progress sent to my phone every working day. Honestly the smoothest building project we have run.
A year post-completion and the thermostatic shower keeps temperature rock-solid even when the kitchen tap is running. Helped with insurance paperwork when we wanted to add the upgrade on the policy. Genuinely best home-improvement money we have ever spent.
