    Excellent service from Ben at Seastack Mechanical. Ben demonstrated exceptional professionalism, honesty, and work ethic throughout the entire job. His response time was very quick, and he was a pleasure to work with. Although I had mistakenly omitted some of my requirements in the original work order, Ben did not hesitate to return to my home a second time to ensure everything was completed exactly as I wanted. What impressed me most was that he never asked for any additional payment, even though the extra visit was clearly beyond the original scope of work. His positive attitude, integrity, and commitment to customer satisfaction truly stood out. He made sure every aspect of the job was completed to a high professional standard. I am extremely satisfied with his service and would not hesitate to call him again for any future plumbing needs. Highly recommended!

    I recently hired Seastack Mechanical to replace a shower in my basement suite, including demolition of the old shower, plumbing rough-in, slab work, and installation of a new shower system. They also completed a separate project upgrading the home’s main water shut-off valve. From the beginning, Benneth from Seastack was very responsive, polite, and an excellent communicator. He provided a very competitive quote that clearly outlined the project scope and included costs, such as labour, materials, and timeline expectations. I sent numerous emails and questions throughout the planning process to ensure I fully understood the work and expectations. Benneth was always quick to respond, professional in his communication, and very patient in answering my questions. This project involved some complexities related to the existing structure and ceiling height, and he worked through those issues carefully to achieve a professional result. I appreciated that communication remained open throughout the process and that any questions or concerns I had were addressed respectfully and professionally. Benneth was also consistently on time and kept me updated regularly as the project progressed. It was clear he took pride in his work and was committed to making sure the final installation was completed properly. The finished shower looks great, feels solid, and the overall quality of the workmanship was very good. The main shut-off valve replacement was also completed professionally and gave me confidence that the plumbing system was updated properly and safely. Overall, I’m very happy with the final outcome and would hire Seastack Mechanical again for future plumbing or renovation projects.
