Why FS Group

Plumbing for Metro-land semis and Victorian terraces

Need a plumber in Harrow who can clear drains as well? Ours do both. A lot of the borough went up in the 1920s and 1930s, from Rayners Lane to North Harrow. In Kenton, many semis have since gained a rear extension or a loft room. New bathrooms bring new pipe runs, and joints that need watching. For an emergency plumber in Harrow, ring 0800 689 3497.

Thanks to Jordan who was able to fix the drain problem within 1 hour. He is been really professional and fast on fixing what a previous plumber didn't manage to do. We managed to book a slot withing 24 hrs and the price was really good. Job was done, it was left sparkling and finally the sink is working again. Once again, thank you Jordan!

Excellent efficient and courteous service. Mitch called to advise me of his arrival time - and he was punctual. He kept me completely across what was happening and what the costs would be. I don’t feel he wasted a second and he mended my dishwasher brilliantly. I could t be more impressed

Pipe ownership

Who fixes which pipe

In the home
Indoor pipes, taps and toilets are down to the owner. That includes any pipe added for a loft bathroom.
Front garden to front door
From the boundary inwards, the supply pipe is the owner's too. A leak under your front path is yours to repair.
Pavement and road
Past the boundary, the main and the stub to the outside stop tap are the water supplier's. Report a leak there to them.

After a loft conversion, know which valve isolates the new bathroom. It saves shutting off the whole house.

Who we work for

Homes, landlords and businesses

What we see most

Faults we fix most in the borough

Limescale build-up

The capital's hard water furs taps, shower heads and toilet valves. Parts stick, drip or slow to a trickle.

Loft bathroom leaks

A joint above a ceiling can drip for weeks unseen. A brown stain in the room below is often the first clue.

Constant refilling

If you hear the cistern topping up long after a flush, the valve or seal inside has worn.

Cold-weather bursts

Pipes in garages and loft spaces can crack in a deep frost. Shut the water off the moment you spot a leak.

Seized stopcocks

An old stopcock nobody has touched may refuse to turn. We free it or fit a new one.

Dishwasher and washer leaks

A worn hose or a loose waste fitting leaks a little each wash. The floor or cupboard swells first.

Questions people ask us

Can I get a plumber in Harrow out of hours?
Yes. The help desk takes calls 24/7, weekends included. Rates are higher outside weekday hours, and you are told first.
What do I do while I wait?
Close the stopcock to stop the flow. Keep away from wet electrics, and catch drips in a bucket or towels.
How can I tell if water is leaking somewhere?
Shut all the taps and read the meter, then read it again an hour later. Any change points to a leak we can find.
Do you install new toilets and taps?
Yes. We can supply them or fit your own. The same goes for cisterns and shower valves.
How much do your plumbers charge?
On weekdays between 8am and 6pm, each half hour costs £80.00 + VAT. Evenings, weekends and bank holidays are charged at a higher rate, given when you call.
My rented flat has a leak. Who pays?
Most often the landlord. The law says they must keep water pipes, toilets, basins and baths repaired. Let them know straight away.
Can you also clear a blocked toilet?
Yes. Drainage is part of our daily work, so the plumber can clear it while there.
Do you guarantee your plumbing?
Yes. Each repair is backed for six months, T&Cs apply. Call us if the same problem returns within that time.
