We had to have an emergency septic clean out and St. Onge responded quickly. The technician was extremely knowledgeable and through. He went above and beyond to make sure everything was functional and educated us on ways to decrease issues in the future!

Two weeks after we moved into our new house we ran into major plumbing issues. We were so disheartened and stressed to learn we needed to fix such a big issue so soon after just moving in. After getting a bogus quote from a different place, we had St. Onge come out to take a look. Roger was so kind, personable and explained everything. He literally got to work and replaced the old cast iron piping with pvc pipe right there on the spot. Honest, family-owned, friendly and fair. I can’t recommend them enough!!

Fantastic Service for an Honest Price! They know what they are doing! I recently had an issue last winter and had a new heat and hot water system put in by Pine Tree. After we paid over the quoted price for that, we found gas leaks, water leaks, had pipes slamming and breaking connections, etc...We had St Onge finish the job. They installed a pump on the condensate tube and ran a line to a drain instead of under my foundation, which I was told to do by the other party. I had previously been bailing this line with a bucket every 2 days for that last 6-8 monthes...on a brand new heating system. The tech repaired all the leaks from the pipes banging around from the system having air in the lines, they even bled the air from the lines to elimate this issue. Their tech was knowledgeable

From start to finish everything was so easy and efficient scheduling was easy. They fit us in relatively quickly even though it was a last minute call. The driver Roger showed up to pump our tank and he was in and out super quick. The yard looked fantastic. Zero damage done. Couldn't event tell he was there. The only reason I knew when they had come and gone that day was because I was home. We did dig up one cover for them but apparently our tank had two. He did have to go through the trouble of digging up the other cover. No complaints about that whatsoever. Super great company. Can't recommend them enough. Roger was so friendly and genuinely seems to enjoy what he does we can't recommend them enough!

Cannot say enough good things about the communication, collaboration, and integrity of St. Onge. To quote Josh, "I've never seen anything like this," after discovering a multitude of issues with our pump and pump tank. The inspection, assessment, solution, and execution were completed seamlessly. We weren't oversold or under-informed at any point in the process. It's no wonder they come so highly recommended.
