Scope of Works
Assess seized, leaking or inoperative indoor stopcock and identify main incoming pipe material.
Isolate the supply (external water‑board valve or local pipe‑freeze kit) and drain down if required.
Remove or service existing valve: free spindle, replace gland packing/washer, or cut out corroded body.
Fit new stopcock or service kit, using PTFE tape/compound and correct pipe fittings.
Pressurise & leak‑test, exercising the valve through full travel.
Re‑insulate and label the valve position; issue a short service report with advice on periodic operation.

Questions to Ask Your Trade
Will you freeze the pipe or shut off at the street valve, and is that included in the price?
Do you carry a range of valve sizes/materials on the van to finish in one visit?
Is the call‑out fee deducted from the final bill if the job proceeds?
What warranty do you give on the new valve and workmanship?
How will you protect flooring and units while cutting or draining?
Are you WaterSafe/CIPHE registered and fully insured?
If extra work is found (e.g., corroded tails), how will additional costs be agreed?
How to Avoid Surprises
Clear clutter around the stopcock and provide easy access to any boxing‑in screws.
Reserve close parking for a van carrying pipe‑freeze gear.
Check the street shut‑off valve is visible and not buried under soil or paving.
Photograph current damp or damage for your records before work starts.
Confirm whether evening or weekend attendance will trigger emergency rates and higher call‑out fees.
