Vaillant boiler repaired

My vaillant eco tec plus boiler was showing a f27 fault code and needed the pcb board replaced. Alan did the work calmly and efficiently and with clear explanation. He also sorted out the thermometer and advised on possible future issues with this 9 year old boiler.

Toilet collapse in a time of virus

I was home and sick with food poisoning when my toilet kept running wasting loads of water. I called Alan and he came round the next day and wrestled with my toilet. He applied a fix, then returned the next day with the right part. He also checked over my boiler and gave me some good tips on keeping it running smoothly. He gave a reasonable price and checked it was ok with me before starting work. His work is first class and I would use him again and again. Thanks Alan.

Alan came round promptly to replace a broken tap. He did a fast and efficient job and charged a fair price. Not only is he a consummate professional but he’s also a genuine and trustworthy guy! I have no hesitation in recommending Alan for any plumbing needs you have.

I called Alan at a time of great vulnerability, during the pandemic in 2020. My wife is severely disabled, and we were shielding both her and her elderly mother. After a number of attempts to resolve our heating issues - even by a large, well known British supplier - our heating was still not working effectively. Our radiators were also beginning to pinhole, and there were other odd issues that no one would come out for. We had just said goodbye to a plumber who had hospitalised himself by not wearing appropriate safety gear. Then along came Alan Mack. He was friendly, knowledgeable, professional, and helpful to the point of explaining everything I didn't understand, in terms I could. He took a single day to resolve every plumbing issue we had, route our pipes properly, replace 7 radiators, and convert our gravity-fed system to pressurised. To my shame, it has taken me more than a year to get around to leaving this review. We have never had to call him back, but we would not hesitate to call him again, or to recommend his services to anyone.

Alan replied promptly and courteously to my initial enquiry. After a helpful conversation, in which he indicated how I could make the most economical choices, we agreed a date for the work to be done. Alan installed a new mixer tap in my kitchen - not an easy task as he had to pull out the dishwasher to gain access to the infrastructure of my sink. He also repaired a mystery leak under the sink. An issue with the toilet cistern was solved by replacing the ball valve. He had anticipated this problem and had put a replacement in his van, just in case. Finally, a heating job: my gas fire was not working so Alan gave it all a thorough clean to remove debris that had accumulated. He also advised that I buy a new CO detector and that I have the chimney swept. At every stage of each job, Alan kept me informed of the steps he was taking. And everything was left spotless after he had finished. A good afternoon's work!

Alan fixed our bath tub that wasn't installed well initially. He listened and understood what we needed, he explained things clearly, and offered advice. Thoroughly recommended.

Alan did an excellent job replacing my broken boiler. He was patient and thorough in explaining what was wrong with the old boiler and the pros and cons for replacement versus repair. Once I agreed on replacement he walked me through the justification for which boiler model was appropriate and prepared a quote for the work. His team completed the work in less time then projected and cleaned up completely when everything was done. I would recommend him without hesitation and he will be my first call should ever the need arise.
