    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!

Seasonal Advice

Booking before the rain beats booking during it.

November is the wettest month in Metro Vancouver, and water damage is now the number one home insurance claim in Canada. These are the eight jobs worth doing between September and December — sump pumps, backwater valves, perimeter drainage, hot water tanks, boiler service, leak detection and freeze protection — and why each one is cheaper and calmer in autumn than in January.
