Qwentin G.
Completed the plumbing inspection today. I looked at the fixtures and drains and everything looked great. Due to the age of the water tank I didn't flush it. The client mentioned that the baseboard in the basement doesn't work anymore. After completing a diagnosis I found that the zone head has failed. I will send over an estimate to replace the zone head.

Completed the Rinnai tankless water heater maintenance today. I started off with running a cleaner through it for 35 minutes. After that I flush 10 gallons of water through it. I cleaned the water inlet screen. I vacuumed out the inside of the unit and the air filter. I checked incoming gas pressure and that was according to manufacturer specifications. I labeled a few emergency shut-off valves. I also completed the plumbing inspection today. I checked all the fixtures and drains and everything looked great. The only thing that I noticed was one of the heads on the water soft tank has been leaking water so I notified and showed the client.

Qwentin G.
Completed the plumbing visit today. I checked the fixtures and drains in the house and everything looked good. I labeled some emergency shut off's in the basement. I did not flush the water tank due to the age and no record of it being flushed. The tank is 9 years old and we don't like to flush tanks if they're over 6 years old and haven't had the maintenance done on them before. The tank looked to be in nice condition though. The boiler relief valve has been leaking so I will send over an estimate to replace the relief valve and add glycol back into the system. Will also send over an estimate for the toilet flapper.

When a GSMS contractor comes to your home, it’s not just another contractor doing a job, it’s a personable experience from someone who truly cares about the neatness and quality of their work to the quality of their relationship with you, the customer… they quickly feel like an extension of your family making you look forward to their visits and not feeling concerned in any way how it’s going to go. Always 5 stars from me and two thumbs up, if I can count my big toes, it’s 4 digits up from me!! 👍👍👍👍🙂🙂

Adam, Quin and Mark did a wonderful job installing my replacement oil boiler and oil tank. I have trusted GSM for 3 installs at my house because of their professionalism, workmanship, honesty, transparency and integrity for how they conduct their family business. Everyone who has worked at my house has always been informative, on time and respectful. I would recommend GSM to anyone who needs to have major plumbing or heating/cooling done in their home. Gina in customer service is the best at relaying information and gets back to you in a timely fashion. Zak is wonderful to work with and the entire team at GSM treats you with kindness. Thank you again for another wonderful experience because when it comes to your home it is one of the largest investments you will make in your life, and I trust GSM to be there for me in the future.
