Reviews
What customers say
Several customers describe responsive service and professional, thorough technicians. One customer praised a heat-repair technician’s meticulous work and cleanup; another said the crew arrived the day of a plumbing-backup call and provided a detailed after-action report. Price and billing concerns recur: one customer called a kitchen-faucet replacement unreasonably expensive and said follow-up calls repeated the fixed-price policy; another questioned a garbage-disposal charge but later praised the company’s explanation of costs, while a third found the required collection of card details alarming and said a billing adjustment remained pending despite the company’s assurance it would adjust the balance.

Frequently Asked Questions
How do Magnolia’s automatic shut-off valves work?
The valve is installed where the main water line enters the home and works with sensors. When the sensors detect an unusual amount of water, the system shuts off the water supply.
