Frequently Asked Questions

Find answers to common questions about our plumbing services, pricing, and procedures. We're here to help you understand what to expect.

We handle a comprehensive range of plumbing work for residential and commercial properties. This includes emergency repairs such as burst pipes, severe leaks, and blocked drains that require immediate attention. We also manage routine maintenance tasks like tap repairs, toilet installations, and radiator servicing.

Our team works on complete bathroom and kitchen installations, boiler servicing and repairs, central heating systems, and water heater replacements. We're equipped to diagnose and fix issues with low water pressure, noisy pipes, and drainage problems. Whether it's a minor drip or a major system overhaul, we have the tools and expertise to get the job done properly.

For genuine emergencies such as burst pipes, major leaks, or complete loss of water supply, we aim to have a qualified engineer at your property within 90 minutes during standard working hours. Our response time may extend to 2-3 hours during evenings and weekends, depending on your location in London and current demand.

When you call, we'll assess the urgency of your situation and provide a realistic arrival time. We keep our vans fully stocked with common parts and tools, which means we can often complete repairs on the first visit. For less urgent issues, we typically schedule appointments within 24-48 hours at a time that suits you.

Yes, we provide free, no-obligation quotes for all planned work such as bathroom installations, boiler replacements, and heating system upgrades. For smaller jobs that can be described clearly over the phone, we can often give you an accurate price estimate immediately.

For larger projects, we'll arrange a site visit to assess the work required, take measurements, and discuss your specific needs. This allows us to provide a detailed written quote that breaks down labour costs, materials, and any additional expenses. Our quotes are valid for 30 days, and we never add hidden charges. If unexpected issues arise during the work, we'll discuss them with you before proceeding.

All our engineers hold relevant qualifications including City & Guilds certifications in plumbing and heating. Those who work on gas appliances are registered with Gas Safe, which is a legal requirement in the UK. We maintain comprehensive public liability insurance covering up to £5 million, protecting both you and our team.

Our staff undergo regular training to stay current with building regulations, new technologies, and safety standards. We can provide copies of certifications and insurance documents upon request. After completing work on gas appliances or certain installations, we'll issue the appropriate compliance certificates as required by law.

We accept multiple payment methods for your convenience: cash, all major debit and credit cards, bank transfers, and contactless payments. For larger projects, we can arrange payment in stages - typically a deposit to secure materials, a mid-project payment, and final settlement upon completion.

Payment is due upon completion of the work unless alternative arrangements have been agreed in advance. We'll provide you with a detailed invoice showing the breakdown of all charges. For emergency call-outs, payment is expected on the day of service. We don't require payment before starting work on emergency repairs.

We provide a 12-month guarantee on all labour for standard repairs and installations. This means if an issue arises with our workmanship within that period, we'll return to fix it at no additional charge. Parts and materials come with manufacturer warranties, which vary depending on the product - typically ranging from 1 to 10 years.

For boiler installations, we offer extended warranty options through manufacturer schemes. Our guarantee doesn't cover damage caused by misuse, lack of maintenance, or work carried out by other contractors. We keep detailed records of all work completed, making it easy to track what's covered under guarantee.

Yes, we work with both residential and commercial clients across London. Our commercial services include maintenance contracts for office buildings, restaurants, retail spaces, and small industrial units. We understand that business downtime costs money, so we can schedule work outside regular hours to minimise disruption.

For commercial clients, we offer planned maintenance programmes that help prevent unexpected breakdowns and ensure compliance with health and safety regulations. We're experienced in working with landlords, property managers, and facilities teams. Our engineers carry ID and are respectful of your business environment and customers.

Call our main number and you'll be directed to our emergency service. We have engineers on call during evenings, weekends, and bank holidays. While you wait for us to arrive, turn off your water supply at the stopcock if you have a major leak - this is usually located under the kitchen sink or where the water pipe enters your property.

For burst pipes, try to contain the water with towels and buckets, and move valuables away from the affected area. If water is near electrical outlets or appliances, switch off the electricity at the fuse box. Don't attempt repairs yourself if you're not confident, as this can make the situation worse. Our emergency call-out fee covers the first hour of labour, with additional time charged in 30-minute increments.

Our standard hourly rate is £65 for routine work during business hours, with a minimum charge of one hour. Emergency call-outs carry a fixed fee of £95, which includes the first hour of labour. Simple repairs like fixing a dripping tap typically cost between £80-£120, while replacing a toilet might range from £150-£300 depending on the unit you choose.

Larger projects vary significantly based on specifications. A basic bathroom installation starts from £2,500, while boiler replacement typically ranges from £1,800 to £3,500 depending on the model and complexity of installation. We'll always provide a clear quote before starting work, so you know exactly what to expect. Materials are charged at cost plus a small handling fee, and we can source products to suit different budgets.

★ ★ ★ ★ ★
Had a burst pipe emergency at 7am on a Tuesday. Called Ducazu and they had someone at my door within 45 minutes. The plumber diagnosed the issue quickly, explained everything clearly, and had it fixed in under two hours. The price was exactly what they quoted over the phone - no hidden fees. I've already recommended them to three neighbours. This is how emergency service should work.

Needed a complete bathroom renovation. The team did excellent work - new pipes, fixtures, everything looks professional. The only reason I'm giving four stars instead of five is that the project took three days longer than initially estimated. However, they kept me informed throughout and the final result is worth it.

As a landlord with multiple properties, I need reliable plumbers I can trust. Ducazu has serviced four of my flats over the past six months - everything from boiler installations to drain unblocking. Their response time averages 3-4 hours, they provide detailed invoices for my records, and tenants have given positive feedback about their professionalism. The pricing is competitive and transparent. They've become my go-to service.

Called them for a blocked drain. They cleared it and it works fine now. The price was a bit higher than I expected - £180 for about an hour's work. The plumber was polite and cleaned up after himself. Service was adequate, though I might shop around next time to compare prices.

I'm impressed by how they handled my shower installation. The plumber arrived on time, wore shoe covers, and worked efficiently without making a mess. He explained the water pressure issue I'd been having and suggested a solution that actually worked. Total cost was £340 including parts and labour, which matched the quote. Very satisfied with the outcome.

Good work on replacing my old radiators. The heating system now works much better. Took slightly longer than planned but they finished the same day. Would have been nice to get a follow-up call to check everything was working properly.

After three other companies either didn't show up or quoted ridiculous prices, Ducazu was a breath of fresh air. They diagnosed my persistent leak issue that others had missed - turned out to be a problem with the pipe connection behind the wall. The repair took four hours and cost £420, but it's been three months now with zero issues. The plumber even gave me tips on maintaining my pipes to prevent future problems. Finally found a reliable plumber in London.

They installed a new toilet for me. The work itself is fine and the toilet functions properly. Communication could be better - I had to call twice to confirm the appointment time. The plumber was professional once he arrived. Decent service overall, meets expectations but nothing exceptional.

My kitchen sink was completely blocked and water was backing up into the dishwasher. Called Ducazu at 4pm and they sent someone by 6pm. The plumber used a camera to inspect the drain and found the blockage 12 feet down the pipe. He cleared it using professional equipment and tested everything thoroughly before leaving. Cost £215 which included the camera inspection. Very happy with the service.

Winter Pipe Protection: Preventing Frozen Pipes

With temperatures dropping below freezing across London, protecting your pipes becomes essential. We explain which pipes are most vulnerable, how to insulate them properly using foam sleeves rated to -15°C, and what to do if you discover ice formation. Learn about the 72-hour rule for unheated properties and why leaving heating on low (12-15°C) during cold snaps can save thousands in repair costs.

Boiler Pressure: What the Numbers Actually Mean

Your boiler pressure gauge should sit between 1.0 and 1.5 bar when cold. We break down what causes pressure drops (typically 0.2-0.3 bar annually through natural evaporation), how to safely repressurise using the filling loop, and when readings above 2.5 bar require immediate attention. Includes step-by-step instructions for Vaillant, Worcester Bosch, and Baxi models commonly installed in London homes.

Solving Low Water Pressure in Victorian Properties

Many period homes in Chelsea and Kensington experience pressure below 1.5 bar due to original 15mm copper pipes and gravity-fed systems. We examine practical solutions including pump installation (typically boosting pressure to 3.0 bar), replacing corroded pipework with 22mm diameter pipes, and upgrading to mains-fed systems. Real case study from a three-storey townhouse where we increased shower pressure from 0.8 to 2.2 bar.
