Areas to Watch

Pricing structure appears excessive for simple jobs ($350 for 15 minutes of work to replace outdoor tap)

Poor customer service when issues arise (described as 'disengaged', threatening email over disputed charges, defensive about faulty products)

Warranty disputes and lack of accountability (1-year warranty on faulty product, customer forced to resort to online resources)

Featured Review

From Google

“

Earlier this year, we worked with St Amant H S & Sons Inc to install a new furnace, and everything went perfectly. The team was professional, efficient, and cleaned up after themselves. Our new furnace looks great!<br><br>More recently, we hired them again to replace our water pump and repair the foot valve in our well. They went above and beyond to help us resolve these issues. We’re very happy with their service and would definitely recommend them — very nice people to deal with!
