A bathroom is waterproofing, falls and ventilation before it is tiles. Get the drainage runs, the tanking and the extraction right and the finish lasts. Get them wrong and it fails behind the wall. We handle the strip out, the first fix, the tanking, the tiling, the fit out and the certification. This page covers what a bathroom project involves in Brentwood.
Drainage is inspected before backfilling, and the electrics need certifying
Brentwood Borough Council's building control inspection list includes drainage prior to backfilling, alongside excavations and prepared designed foundations prior to concreting. Where a bathroom project puts in new below ground drainage, that stage is seen before the trench is closed rather than afterwards.
The council also issues a completion certificate on satisfactory completion of the project, and where electrical work is involved it requires a Part P electrical certificate first. Bathroom electrics are zoned work, so the certification is not optional. We coordinate the application, the inspections and the paperwork that comes out of them.
Brentwood lies within an area of Serious Water Stress
The Brentwood Water Cycle Study 2018 identifies the borough as lying within an area of Serious Water Stress, and the Local Plan applies a limit of 110 litres per person per day for water use in new homes. The same study found sewerage infrastructure in the north of the borough operating at full capacity.
A refit is not a new home, so that litre figure is not a standard you have to meet. It does explain why the flow rates of a shower and a bath filler are worth deciding deliberately, along with the size of the cylinder feeding them. We price the options rather than assume one for you.
Brentwood borough drains into two different river basin districts
The borough straddles two river basin districts. The River Wid lies in the Anglian River Basin District, while the Mar Dyke and the Roding, Beam and Ingrebourne catchment lie in the Thames River Basin District. Where surface water and foul water go has a different answer in different parts of the borough.
For a bathroom that matters when a new soil connection or a rerouted waste has to be made. The point is to establish where the existing runs go before pipework is cut into, not after. We trace them at survey and set the new runs out on a drawing you can see.
- Ventilation and extraction ducted to outside
- Pressure and leak testing before any tiling starts
- Notifiable bathroom electrics certified under Part P
- Tanking membranes and waterproof boards behind tiles
- Shower pumps and pressure improvements where flow is poor
The GS Renovation Difference in Brentwood
The failures in a bathroom are hidden ones: a waste run laid at the wrong fall, tanking stopped short of the shower zone, an extractor that moves too little air. Those are decided at first fix, weeks before the first tile goes on, and they are why we keep the whole sequence under one contract rather than splitting the plumbing from the tiling. Where a bathroom is being moved or a wall opened up, we appoint the structural engineer and build to their calculations. GS Renovation Ltd is a contractor, fully insured, registered in England, company number 14611254, and it coordinates the building control application and inspections.
