We were recommended D.W Dunn by neighbours who all gave good reviews and we have now used them a few times. We are so glad to have found them. Recently, we had an unexpected loss of hot water. Andy organised an engineer to get to us in super quick time and the problem was immediately resolved by Dan. The team provide a great service, always professional and efficient. They always seem to go over and above to help customers and resolve the issues.

My wife and I turned to this company for our water softener system following recommendations from neighbours. We are glad we did. From our first enquiry about a water softener, through the prompt initial inspection visit and quotation, to installation of the softener soon after our acceptance of the quotation, it has been a pleasure dealing with the firm. It is professional, efficient, and friendly, and its representatives respond patiently and helpfully to the most minor question. We are very pleased with our water softener system, and we have no hesitation in recommending D W Dunn Ltd.

Great work from a great team!
We’ve used DW Dunn several times and I wouldn’t work with any other plumbing firm now. They’ve done multiple jobs for us; new boiler, radiators, taps etc. They have just done all the plumbing work for our new kitchen and once again they’ve been amazing. The team in the office bent over backwards to work around our moving schedule with unlimited patience. And the team; Dean, Dan, Matt and Kieron did a great job, as they always do. It helps that the team are polite, professional, courteous and love our dogs as much and they love them! They are tidy, trustworthy and work with the minimum of supervision. Very highly recommended.

Very reliable & quality service
We invited Andy Harper, MD of D W Dunn Ltd to provide a quotation for a water softener and he turned up exactly on time. He took a lot of time explaining how the Kinetico water softener worked and he knew immediately where the machine could be located. He provided a real professional service. Dan, the installer arrived exactly on time and installed the water softener. Absolutely no mess and a beautiful professional pipework installation. No fuss, no aggro and from start to finish and we received top quality service and also at a competitive price. We can highly recommend D W Dunn Ltd for top class quality of service. Thank you.

I have used D W Dunn for years now to fix things, put in a boiler, service my boiler and any heating or water emergency. In my new house switching in the hot water also switched on the radiators. They came the same day and replaced the valve and all works fine. Their staff are friendly and reliable. I can highly recommend them.

We use DW Dunn for our boiler annual boiler maintenance. Our old system was over 30 years old still working but seemed the right time to change. Andy came to assess the best options for our size of house and gave us a very detailed quotation for a replacement. We also requested new thermostat valves on the radiators and the whole system drained and flushed through. Andy recommended a Worcester Bosch Greenstar Dansemoor External Combi . The engineers were a great team, led by Dan with Dean,Dan,and Kieran they were all extremely professional,polite and very pleasant to have in our house, nothing was too much trouble. Dan thought through each stage of the installation systematically and explained everything extremely conscientious. The team took great pride in their work. We are delighted with the outcome it’s been in a month since installation,we have a toasty warm house, every room is now very controllable with an efficient external boiler certainly using less oil also very quiet . The invoice came in right on quotation. The App and ease of setting the schedule is very easy. All in all superb thoroughly recommend. Thank you

I had a water softener, water cartridge with three way tap, and an outside tap providing hard water for the garden all installed. The excellent initial survey by Andy provided all the relevant detail necessary for me to make a decision on my requirement and price. I had some installation concerns but Andy made me feel very confident that nothing was too much trouble and the installation would be very straightforward. Dan and Kieran arrived as planned and on time on the installation day and proceeded to carry out a first class job. The end result was very pleasing and very tidy. All rubbish was removed, the appliances put back in situ, and the utility room cleaned. The guys were pleasant and very helpful, taking me through the various water controls etc as well as the reordering process for salt and water cartridge. I was very pleased with the results and great service and would certainly recommend D W Dunn.

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.
