Plumbers 365 is a national drainage and plumbing company with engineers working across the country, including Cardiff. We handle everything from a slow-draining kitchen sink to a collapsed sewer, and we do it around the clock — there is no separate out-of-hours company and no answering service between you and an engineer.

Our teams are fully insured and DBS-checked, and the vans carry jetting equipment, drainage cameras and repair kit as standard, so most jobs are finished on the first visit rather than booked in for a second. We are members of the NADC and the FSB, and our work is backed by our own guarantee.

Whatever the problem in Cardiff, you will get a fixed price before we start and no call-out charge. Call 0800 755 5566 and we will tell you honestly how quickly we can be with you.

1. Stop using water. No flushing, taps, washing machine or dishwasher. Every litre adds to a system that cannot cope.
2. Keep clear of standing sewage. It carries harmful bacteria. Keep children and pets away from the area.
3. Do not lift manhole covers. Trapped gases and the risk of falling make this genuinely dangerous. Our engineers carry the equipment to do it safely.
4. Move what you can. If the overflow is indoors and it is safe to do so, lift rugs, furniture and anything electrical clear of the water.
5. Call us on 0800 755 5566. The sooner we are on the road, the less damage there is to put right.

Our Cardiff engineers cover the full town and the surrounding area, with vans positioned so that most callouts are reached inside a 60 to 90 minute window. We work around the clock, including weekends and bank holidays, and there is no call-out charge whatever time you ring.

If you are just outside the areas listed below, call us anyway on 0800 755 5566. We will tell you honestly how long we would be rather than quoting a time we cannot keep.

Cardiff receives soft water from Dwr Cymru Welsh Water.

What actually blocks the drain is usually fat. Any scale present has already reduced the space available for it to move through.

Victorian terraced housing makes up much of Cardiff, and its clay drainage has been in the ground over a century.

Clay endures but does not tolerate movement. Joints displace, roots invade, and the second callout to a property usually finds damage rather than a simple obstruction.

We look before we quote. A camera inspection is usually the first step, so the price is based on the actual problem.

Rodding and high-pressure jetting clear the great majority of blockages immediately. Structural damage is a different job, and we will show you the footage and quote before starting.

You will never see a call-out charge on one of our invoices.

You are quoted a fixed price before work begins, and that price is honoured regardless of how long the job takes.

Charges reflect the actual job. Clearing a blockage is one price, excavating a broken drain another, and you will know yours before work commences.

Blocked drain in Cardiff? We are on call now. No call-out fee, fixed prices, and an engineer who can be with you in 60 to 90 minutes. Call 0800 755 5566.

Restaurants and takeaways around Roath and Canton tend to ring mid-service, when a kitchen gully starts overflowing into the rear yard and the kitchen has to stop.The survey usually finds grease built up through the full run to the interceptor, made worse by a grease trap undersized for the kitchen's actual output.We jet the line clear and descale the interceptor, then advise on correct trap sizing and a realistic maintenance interval rather than leaving it to chance.Kitchens are normally back in service within two hours. Most sites then move onto scheduled quarterly jetting, which costs far less than an emergency mid-service.
