The questions we are asked most
Answered without the sales gloss. If yours is not here, ask — we would rather give you a straight answer on the phone than have you guess.
All questions
Everything, in one place.
Grouped as they tend to come up: who is responsible, what it will cost you in disruption, and whether we are allowed to do the work.
See all FAQsDo you cover London?
Yes. London is a core operating area for supply pipe repairs, replacement and installation, water pipe installation and new connections, alongside Hertfordshire, Bedfordshire and the surrounding counties. If you are unsure whether we reach your postcode, ask — we will tell you straight away.
Will you have to dig up my driveway or garden?
Usually not. We locate leaks acoustically before breaking any ground, and install replacement pipework using trenchless impact moling wherever ground conditions allow, so surfaces stay intact. Where excavation is unavoidable, tarmac, block paving, paths and landscaping are reinstated as part of the works.
Can a supply pipe be repaired instead of replaced?
Often, yes. If the pipe run is otherwise sound and the defect is isolated, a targeted repair is the faster and less disruptive option. Where the pipe is lead, undersized, or failing in more than one place, replacement is the better long-term answer. We survey first and tell you which applies.
Do you respond to emergencies?
Yes. We operate a 24/7 emergency response for burst pipes, major leakage, sudden pressure loss and other urgent supply failures.
Are you accredited to work on adoptable water networks?
Yes. Cascade holds LRQA WIRS accreditation, is a WaterSafe approved contractor and operates under the WIAPS approved plumber scheme, alongside SafeContractor, SMAS Worksafe, Acclaim and Achilles UVDB Silver Plus. Under WIRS we are accredited to undertake eligible self-lay and contestable works — including new water service connections — within our accredited scope.
Can you manage the water company application as well as the installation?
Yes. As an accredited Self-Lay Provider we prepare and manage self-lay, NAV and new connection applications, liaise with the incumbent water company through the adoption process, and hand over a certified asset with as-built records.
Why does lead pipe replacement matter?
Lead can leach into drinking water, which is a recognised health risk — particularly for children and during pregnancy. Replacing a lead supply pipe with modern blue MDPE removes that risk from your supply and brings the property in line with current expectations.
How do I get a quotation?
Call, email, or use the online enquiry form with basic details of the property or scheme. Domestic supply pipe work can usually be scoped over the phone; development and commercial schemes start with a look at your drawings.
