Reviews
What our customers say
“Called in the morning about a leaking kitchen pipe and it was fixed the same afternoon. Price was exactly what was quoted on the phone.”
“Blocked floor trap in the bathroom that two other people could not clear. Sorted in under an hour and the area was left clean.”
“Very straightforward. Explained why the cistern kept running and replaced only the valve instead of pushing a new toilet.”
“Water stain on the ceiling turned out to be a joint behind the wall. They found it without hacking half the bathroom.”
“Arrived slightly later than planned but messaged ahead. Work on the water heater connections was neat and no leaks since.”
“Dripping tap and a slow basin fixed in one visit. Polite, tidy and no hard selling.”

Plumbing tips
Simple advice that saves repairs
How to prevent blocked drains
Hair catchers, no oil down the sink and a weekly hot-water flush stop most blockages before they start.
What to do when a pipe starts leaking
Close the main stopcock, keep electrics clear of the water, contain the drip and call a plumber before the damp spreads.
How to maintain your water heater
Check the connections above the unit for damp, listen for unusual noise and act early if the water runs cooler than usual.
