What customers say on
Just had my leaky loo fixed through the Northumbrian Water scheme. Excellent service by a guy from Gateshead. Job well done, no problems. 5☆ service.
I got my leaky toilet fixed through Northumbria Water. The plumber was very friendly and polite and in no time the problem was fixed. Very happy customer. Thank you.
We inherited JN Dunn as our remedial installer after purchasing a new build property from Ascent Homes. We expected there to be snags as with any new build home, however 8 months later, and we still have intermittent hot water issues, and today have experienced our third no-showing of an appointment by JN Dunn. The overall aftercare service we have been provided with has been abhorrent, with countless of both technical and customer service mistakes, all of which had a negative impact on us. As JN Dunn has now been removed from their duties working on Ascent Homes properties, I can only presume that we aren’t the only ones who have experienced such issues. Ascent Homes have now been forced to find us an alternative installer for remedial aftercare due to the poor standard of service we have received.
Had a guy out today to my mams house then mine what a credit to the company don't know his name but did a fantastic job and respected both our properties very efficient and pleasant would definitely recommend him
Phoned on the day to cancel my appointment even though the appointment had been booked in the previous week. Broken part fitted which now works worse than before! Cannot get a new appointment for a week! (If they turn up) Phoned asking to speak to a manager but never available, I have asked for a manager to call me back but nothing!!! AVOID!!!
