Fast and efficient service delivery - multiple reviews mention quick turnaround times and same-day appointments

Areas to Watch

Communication failures in complex situations - one detailed complaint about lack of follow-up calls and repeated assurances of callbacks that never materialized during emergency water heater replacement

“

Big shout out to Guest Plumbing and Heating!! Just had my Hot Water Tank replaced and I have to say I couldn’t be happier with how fast and efficient the job was. Trevor was fantastic with the removal of my old tank and replacing it with a brand spanking new one!! The guys from Guest Plumbing and Heating were here first thing in the morning and they were out by lunch and I have hot water running again before I was even able to finish with this 5 Star review! Thanks again Trevor and thanks Guest
