LICENSES: GAS SERVICE

Having grown up in the family business, Jack officially entered the trades and joined the GSMS team seven years ago because it simply felt like the perfect fit. Guided by the Golden Rule, Jack appreciates the genuine kindness of both his colleagues and his clients, and he wants every customer to know that the team will always try to do their absolute best on every job. A natural learner who loves to master new skills, Jack stays incredibly active outside of work. You can usually find him renovating his first house, woodworking, playing the guitar and drums, or experimenting with new recipes on the grill and smoker. Depending on the season, he also loves skiing or cycling. Above all, he cherishes the time he spends with his fiancé, Hope, and their Australian Shepherd, Norman. Jack is also a proud member of the Pointer Fish & Game Club.

Today I replaced 2 outdoor water spigots with new frost free versions. I reccomend a water test due to the old hoses being stuck on and the appearance of a lot of the fittings in the basement. I reccomend replacing irrigation valve and the hose/ drain valve below it.

The display for the MHK2 controller said "REPLACE ME". Homans tech support confirmed that the display needed to be replaced due to a failed sensor or other reason. I replaced with a new MHK2 and everything is operating correctly now.

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!! 👍👍👍👍🙂🙂
