Mark Lindsay & Son exceeded my expectations from start to finish. From my initial phone call to schedule an estimate for repairing or replacing my boiler, their team was responsive, courteous, and exceptionally professional. They were able to schedule a complimentary estimate promptly, without the long wait times I had experienced with other service providers. Approximately 30 minutes before the appointment, I received a text with a photo of Perry, the technician, along with information highlighting his experience. This thoughtful touch immediately inspired confidence and reflected the company’s commitment to professionalism and customer service. Perry was outstanding! He was extremely knowledgeable, patient, and personable, taking the time to thoroughly explain my options and answer all my questions. Most importantly, he demonstrated genuine honesty and integrity. I felt he was looking out for my best interests and helping me find the most cost-effective solution, rather than trying to upsell me on unnecessary work. He was never pushy and made the entire experience comfortable and reassuring. It is refreshing to work with a company that combines technical expertise, responsiveness, and a genuine commitment to its customers. I highly recommend Mark Lindsay & Son and Perry to anyone looking for a trustworthy, knowledgeable, and professional plumbing and heating company. I would not hesitate to use them again!

I had 4 hvac companies out to quote a major job, boiler & water tank replacement. Perry Mandarakas was the only one who actually took his time, meticulously measuring every baseboard and radiator in my home. I can tell he was and still is a fantastic teacher in the trade. I felt like I took a class by the end of his visit! Dean, Tyler, and their install team were all super clean, efficient, also answered all my questions. Thank you all!
Hi Francoi! Thank you so much for taking the time to share your experience with us. We are thrilled to hear that Perry and the entire team provided you with exceptional service and made you feel well-informed throughout the process. If you have any more questions or need further assistance in the future, feel free to reach out. We truly appreciate your feedback!
