New-build plumbing in East London
Blackstone provides plumbing for new builds, homeowners, builders, contractors and property developers. Engage the plumbing team before concrete and finishes restrict the possible pipe routes, and make the agreed responsibility boundaries clear.
Design coordination before site installation
Provide the plans, fixture schedule, hot-water requirements, intended occupancy and construction programme. Confirm supply and drainage connections, any approvals and the work allocated to other trades. Changes in bathroom or kitchen positions can affect buried drainage, ventilation and access.
Drainage and water-supply rough-in
Rough-in establishes the concealed pipework and connection positions before the final fixtures are fitted. Coordinate penetrations, levels and access with the builder. Checks required for the specific installation must happen before pipework is covered; reopening completed slabs or walls is disruptive and can increase cost.
First fix, finishes and fixture installation
Protect unfinished connections from damage and contamination. Confirm the selected fixtures are compatible with the installed positions. Waterproofing and tiling depend on coordinated handovers, particularly at shower wastes and pipe penetrations. Identify who checks each stage before the next trade closes it.
Final checks and handover
The agreed scope should cover appropriate leak, flow and drainage checks, safe access to isolation controls and any required documentation. Ask for a record of concealed routes and changes where available. A final visual check is not a substitute for the checks needed during construction.
Quoting for builders and developers
Clarify whether the quote covers one dwelling, several phases or communal systems. Specify fixtures supplied by others, excavation, reinstatement, testing, approvals, electrical work and variations. Discuss realistic sequencing rather than assuming the plumber can resolve unplanned changes at the end of the build.
Frequently asked questions
When should the plumber join a house build?
Before slab, drainage and service routes are finalised. Early coordination reduces the risk of inaccessible connections or expensive layout changes.
Does Blackstone work with building contractors?
Yes. Provide plans and a programme so project stages, inclusions, handovers and responsibilities can be agreed.
