During a small refurbishment a workman drilled through the underfloor heating pipe. Dunns were at our property within hours. Obviously with a flagstone floor this repair was going to be a big job, and a very messy job. So we all thought. Dan was very polite and did what he could to help us. He didn’t have the parts he needed so returned to the office to place the order. A few days later he returned with Dean. Words fail me. Dean saw a different way of going about the repair without lifting the floor. Unbearable! But what a Stirling Job. I’ve waited 20 days to do this review I wanted to be 100% sure the pipe was fixed. It is. No water, full boiler pressure and underfloor heating working as it did. Thank you Dan & Dean. Dan gave all the credit to Dean which was a nice thing to do. I’ll never go anywhere else for a plumber. These guys are the BEST. Thank You.

We have been using DW Dunns services for a few years now so it was about time we left a review. As a local rental agent for a number of holiday home, DW Dunns have been our 'go to' when it comes to our annual services and gas certificates, but also as our emergency contact when things invariably go wrong. A trusted and valued partner which has been built through reliable, consistent and honest work over the past decade and would thoroughly recommend.

During my boiler service my old boiler was condemned and although DW Dunn looked into repairing it for me it was agreed that this was not going to be a viable option. My new boiler however would not fit into the existing space so it would have to be moved. This then involved a lot of extra work, including getting scaffolding and a roofer. Andy Harper at DW Dunn sorted everything for me, which was amazing, and I was kept informed every step of the way. On the day of the installation, the two heating engineers (Dan and Kieran) were brilliant. They went above and beyond in every way. Their workmanship was excellent, and they respected my property to the very last minute. Everything that was arranged happened exactly on time. Delivery of the boiler, scaffolding, electrician, and roofer. At no point did anything go wrong. The agreed budget was stuck to with no extra costs at the end, and my new boiler is working beautifully. Andy Harper also checked in with me once the work had finished to make sure I was happy with everything. Overall, I could not have been happier.

DWDunn replaced a 17 year-old gas heating boiler with a Worcester Combi. They arrived on time, laid protective floor coverings and worked fast to complete the installation in 2 days. They cleared away all of the old equipment and left my home & garden probably cleaner & neater than before they started the job! The two installers were very knowledgeable and polite. They gave me a complete training on the Hive thermostat and associated phone app. First class service - highly recommended.

The whole operation was very professional with Andy, the manager, visiting promptly and discussing options clearly. We knew what we wanted and had a good understanding of the system. We needed to have our solar hot water system drained and disabled, which may have been outside the experience of some heating engineers. The installation, and work on the solar panel , was done efficiently and with minimal disruption, and the new 28mm pipes that were required were fitted as unobtrusively as possible. I felt that Dan, the engineer, was working to high standards and wanted to satisfy our needs as best he could. We were both impressed with the work and the end product. No mess, good workmanship. Nice people.

Exceptional work to fit our Water Softener

We were quoted to fit a water softener in a specific location, to avoid the loss of a kitchen cupboard. Unfortunately, because of problems discovered on the day, it was not possible to install as we had hoped. However, we were given lots of ideas to mull over and eventually went for the obvious one; we installed in the kitchen cupboard. The installer said he would do everything to minimise the loss of cupboard space and true to his word he did exactly that. He repositioned the existing pipework and made more space available as promised. The finished look was the work of a craftsmen who takes pride in his work. He also did various other plumbing jobs around the house we had asked for and once again the finished work was excellent. Take a long bow Dean for work extremely well done! Yes, I would thoroughly recommend this firm based on my personal experience. I hope you enjoy the same service.

I have used DW Dunn several times. Both in emergency leak situations and general plumbing work. The most recent work was to fix a leak a few days before Christmas. They were so helpful, arrived promptly and found fault completed the work very quickly. I really appreciated the attention to detail when clearing up and left no trace. They make no fuss but deliver excellent service. Good trade people you can rely on can be hard to find and I strongly recommend using DW Dunn.

The service I received was excellent right from the start. I was given all the advice I needed so was able to make an informed decision. The staff who came to fit the machine were equally friendly and professional. I would have no hesitation in recommending them as a result.

I was quoted for a like-for-like replacement boiler for my oil-fired central heating system in October. I was extremely impressed by the handling of my initial query with everything explained fully before I was given a quote. I had considered postponing until the following spring, but the old unit began leaking. I contacted DW Dunn and although extremely busy, they were able to offer carrying out the work within three weeks due to a cancellation. They arrived promptly on the agreed date and removed the old boiler, before carrying out work to the piping and addressing the issues surrounding my existing flue outlet. The latest regulations required a pipe to be fitted above the gutter level and away from a neighbouring property. All works were carried out by two excellent installation engineers who were hard-working, did a clean and tidy job and were very friendly throughout. The job was completed on time within two working days, on budget and (one month later), the house has a much quieter heating system now. I really am extremely pleased with the work carried out and wouldn't hesitate to recommend this company to others. A first-class experience.

We had DW Dunn recommend and install a water softener. All of their interactions were incredibly prompt and helpful and we are very happy with their work. They have also visited on a number of occasions to advise in heating queries. We would recommend them to anyone.

I needed an old oil boiler replacing. This was not a simple job as due to changes in regulations a new flue was needed and the new boiler needed to be installed in a new location outside of the main house. The job was done effortlessly by an excellent team who completed the work to a very high standard and on time. Throughout the process with the company has been excellent, and they really care about their customers. I could not be more pleased.
