Average job size is meaningful — multi-bathroom houses are common. ### What Billericay Customers Ask For Strong demand for full luxury bathroom and en-suite suites, system boiler upgrades for multi-bathroom houses, wet underfloor heating retrofits, and air conditioning installs across the executive housing stock.

Billericay Property Issues ## What Actually GoesWrong In Billericay. Specific issues we see again and again across Billericay housing stock — the things a generic national fitter quotes around, then bills you for mid-job. ### Single combi feeding multiple bathrooms Plenty of Billericay executive houses run a combi that can't keep up with two or three bathrooms at once. We resize and convert to system or unvented with proper recovery. ### Period property pipework in High Street stock Listed and period properties through Billericay's older centre often hide iron or lead pipework. We assess at survey and run new pipework discreetly without damaging original features. ### Wet UFH retrofits without proper insulation underneath Retrofitted UFH that isn't insulated below loses most of its heat into the slab. We insulate, screed and commission properly. ### Hard water across CM postcodes Limescale damage to combis, valves and chrome is heavy. We flush as standard on boiler swaps and recommend scale inhibitors on every install. ### Air-con installed badly by handymen Plenty of executive AC installs were done by handymen — undersized, poorly sited, never properly commissioned. We survey, size correctly and commission to manufacturer spec.
