Watford areas

We cover every part of Watford

We cover the WD17, WD18, WD24 and WD25 postcodes, plus Oxhey in WD19. That takes in Cassiobury, Nascot Wood, North Watford, West Watford, Holywell, Garston, Oxhey and the town centre.

The age of the house tells us a lot before we arrive. The terraces around Vicarage Road and West Watford date from the late 1800s and early 1900s, and some still have old lead or iron supply pipes, a common reason for weak water pressure. North Watford and Garston are largely 1930s and post-war semis, where older open vented heating systems with a tank in the loft are still common. Cassiobury and Nascot Wood have larger houses with more bathrooms and bigger hot water demands. Around Watford Junction and the town centre there are many flats, where the water often has to be isolated through the managing agent before work can start.

Emergency Plumber in Watford

For a burst pipe, a leak you cannot stop or a boiler that has failed in cold weather, phone us directly. We will tell you straight how soon we can reach you. Our route is down the A405 from St Albans, which brings us into Garston and North Watford first, then on to the town centre, West Watford, Cassiobury and Oxhey.

Before we arrive, turn off the stop tap. In Watford’s older terraces it is often under the kitchen sink or in a cupboard by the front door. If you live in a flat and cannot find it, your managing agent or building caretaker should know where the isolation valve is.

Maintenance Plumbing in Watford

Small plumbing faults in Watford tend to follow the age of the property. In older terraces it is worn stop taps, tired pipework and weak pressure. In flats it is usually toilet valves, mixer taps and shower cartridges. Everywhere, the hard Affinity Water supply leaves limescale that shortens the life of taps and valves.

We repair dripping taps, leaking pipes, running toilets and faulty showers for homeowners and landlords, and we look for the cause so the same fault does not come back a few months later.

Gas Boiler Services in Watford

Our Gas Safe registered engineers install, replace and repair gas boilers throughout Watford. When a boiler breaks down we diagnose the fault first and tell you the cost of the repair before any parts go in.

If you are replacing an old boiler, the right choice depends on the house. A combi suits most terraces and smaller semis. A larger home in Cassiobury or Nascot Wood with two or more bathrooms is usually better served by a system boiler and an unvented cylinder. We will explain the options and the reasons for our recommendation.

Central Heating Services in Watford

Cold spots, radiators that only warm at the top, and pipes that bang when the heating comes on are the complaints we hear most about older central heating systems. In 1930s semis the original pipework is often still in place and can be heavily sludged.

We repair heating faults, replace radiators and valves, power flush where sludge really is the cause, and convert old open vented systems to sealed ones. We also fit new full heating systems where the existing one is beyond economic repair.

Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house. The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work. I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

Excellent service from Alban Plumbing and Heating Ltd. I contacted them for a plumbing and heating issue at my property in St Albans, and the whole experience was excellent from start to finish. The engineer arrived on time, quickly identified the problem, and explained everything clearly before carrying out the work. The job was completed to a high standard, and everything was left clean and tidy afterwards. What stood out most was their professionalism, reliability, and honest approach. Communication was great throughout, and the pricing was fair with no unexpected surprises. I would highly recommend Alban Plumbing and Heating Ltd to anyone in St Albans and the surrounding areas looking for a trustworthy plumbing and heating company.

Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come. His 5 star status is well deserved.

Frequently asked questions

Which parts of Watford do you cover?
We cover WD17, WD18, WD24 and WD25, plus Oxhey in WD19. That includes Cassiobury, Nascot Wood, North Watford, West Watford, Holywell, Garston and the town centre.
Watford is around eight miles from our St Albans base, mostly along the A405. Timing depends on the day’s bookings and the traffic around the M1 and M25 junctions, so call us and we will give you a realistic arrival time.
Yes. In Watford’s older terraces weak pressure is often down to an old, narrow supply pipe or a partly seized stop tap. In other homes the cause is a blocked filter, a failing pressure valve or a scaled up shower. We test the incoming pressure and flow first, so you only pay for the fix that will make a difference.
Yes. We check whether the problem is trapped air, a stuck valve, poor balancing, a weak pump or sludge. Sludge is common in older systems in North Watford and Garston, and a power flush helps in those cases. If the cause is something simpler, we will fix that instead.
Yes. We install, repair and service unvented hot water cylinders, which are common in Watford’s flats and larger houses. Typical faults are a dripping pressure relief valve, a failed expansion vessel or a faulty thermostat. An unvented cylinder should be serviced every year to keep it safe.
Yes. Watford’s water is hard, so limescale builds up in taps, showers, cylinders and boilers. We replace scaled up parts and can fit a water softener to protect your plumbing and appliances.
