What our customers say

The blokes were lovely! They were friendly, respectful and polite. They went above and beyond to stay to finish things off. Defluo’s workmanship is of very good quality and I would definitely recommend them....

West Dartford (Bathroom designed and fitted)

Delighted with the job Defluo did. The work was fantastic. They designed the bathroom very well and did a marvellous job with the installation. I would recommend them to anybody not only for the quality of their work but also for being reliable and trustworthy...

Dartford, Kent (bathroom designed and fitted)

I am really pleased with the bathroom Defluo fitted. They helped us with ideas on how to place different things in the bathroom. The work was carried out efficiently and I was really impressed with their service. They were really nice guys to have working in the house and I would definitely recommend them...

Willmington, Kent (bathroom and wet room designed and fitted)

They were really good in helping us choose designs. We had a blank canvas and Defluo helped us to image what would look good. They made sure that every detail was catered for. Their builders were great, really helpful and went beyond the call of duty!...

Bexley, Kent (bathroom design and fitting)

I was impressed with the advice and service I received from Defluo. They replaced our old oil fired boiler with a state- of-the-art modern boiler which is far more efficient that the old one. Their engineers were very knowledgeable and got us up and running with heating and hot water in no time. I was impressed with the whole set up from how things were managed by the office to the service on the ground. I would have no hesitation in recommending them...

Billingshurst, West Sussex (oil fired boiler installation)

We have worked with Joe Kelly and Defluo for many years and they consistently provide a top rate service. If we have a problem or emergency I can always rely on Defluo to attend at any time of day with a minimum amount of disruption and would have no hesitation in recommending their plumbing, drainage and building services...

Henry Davies
Property Partners

At Bhs we require contractors in whom we can rely upon, contractors who genuinely are 24/7. Defluo not only fit this bracket but they have the correct equipment and materials to ensure the majority of problems are fixed on the first visit. The vans and uniform portray a good image and the staff are polite and professional. I certainly wouldn’t call anyone else should we have a blocked or leaking pipe.

David Mayne
Head of Property Services, BHS

I’ve been in the restaurant business for 25 years and Defluo is far and away the best plumbing firm I’ve used in all that time. The service and the standard of work are both outstanding. They are incredibly quick and very good at keeping you informed.

Greg Abbott
Franchise Holder, McDonalds

Monsoon is committed to working with external contractors who provide the highest standards of service on our portfolio and over the past few years Joe Kelly and the team at Defluo have done so.
