Homes in Harrow

Harrow has a real mix: Victorian and Edwardian terraces near the town centre and Wealdstone, large inter-war semis in North Harrow and Headstone, older properties around Harrow on the Hill, and a large number of purpose-built flats and conversions. Many houses have been split into flats or extended, which affects how water, gas and heating are run through the building.

What Harrow customers call us for

In Harrow we're most often called for new boiler installations and boiler repairs, gas safety certificates for landlords, leak detection in flats where water is coming through to the unit below, blocked drains and toilet repairs, and tap and shower replacements.

Local issues

Common plumbing and heating problems in Harrow

Converted flats

In Harrow's converted houses, one leak can affect two or three households. Pipes often run through shared floor voids, so accurate leak detection matters to avoid opening up a neighbour's ceiling unnecessarily.

Landlord compliance

Harrow has a large rental market. Landlords need annual gas safety certificates (CP12), ours start from £80, and we can arrange access directly with tenants.

Ageing boilers

Many Harrow homes still run older boilers that are inefficient and hard to get parts for. As an approved installer for Vaillant, Worcester Bosch, Navien, Ideal and Main, we fit replacements with warranties of up to 10 years on most models.

Victorian drainage

Older terraces often share drain runs and have clay pipework that can crack or suffer root ingress. High-pressure jetting and drain surveys find and clear the cause.

Winters around Harrow and the wider London Borough of Harrow area bring regular cold snaps, when boiler condensate pipes freeze and exposed pipework in lofts and outbuildings can split. If your boiler stops on a frosty morning, it's often a frozen condensate pipe, something we can thaw and protect so it doesn't happen again.

Looking after your plumbing and heating in Harrow

Most emergencies we attend in Harrow start as small problems: a dripping joint, a boiler that keeps losing pressure, a radiator that is cold at the bottom, or a drain that empties slowly. Dealing with these early is almost always cheaper and less disruptive than waiting for a breakdown. If you notice a damp patch, a rising water bill, a hissing sound when taps are off or a boiler showing a fault code, it's worth a call.

An annual boiler service, from £100, is the simplest way to keep your heating reliable through winter. It checks the boiler is burning safely, cleans key parts and keeps most manufacturer warranties valid. For landlords in Harrow, an annual gas safety certificate, from £80, is a legal requirement, and it makes sense to book both at the same visit.

If your boiler is getting older, parts are hard to find or it keeps breaking down, a replacement may cost less over time than repeated repairs. We'll give you an honest view on site. As an approved installer for Vaillant, Worcester Bosch, Navien, Ideal and Main, we can fit a boiler matched to your home and hot water needs, with warranties of up to 10 years on most models.

In a plumbing emergency, turn off the water at the stopcock (often under the kitchen sink), switch off the electrics if water is near sockets or lights, and call us on 07845 967854. If you smell gas, turn off the supply at the meter, open windows, don't use switches, leave the property and call the National Gas Emergency line on 0800 111 999.

Whether you're in Harrow itself or one of the neighbouring areas, you'll deal directly with Jack Webster, get a clear price before any work begins, and have your home left clean and tidy afterwards.
