Have questions about plumbing in Longmont? We have answers.
Your main water shutoff valve in Longmont is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.
Signs of a slab leak in Longmont homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.
To prevent frozen pipes in Longmont, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.
Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help Longmont homeowners decide between repair and replacement.
Plumber rates in Longmont typically range from $100 to $250 per hour depending on the type of work and time of day.

Our reputation is built on results. Here is what our customers say.
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
"Amazing work. Good people. Reliable. On time and efficient. And prices are definitely hard to beat! HIGHLY RECOMMEND!"
"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."
