Leak Detection Service in Tucson

More than 426+ 5-Star reviews

A hidden plumbing leak can stay quiet for weeks before it leaves obvious damage behind. Damp cabinets, warm spots on the floor, musty odors, stained drywall, low water pressure, or a rising water bill can all signal a leak behind walls, under floors, beneath a slab, or somewhere in the plumbing system.

At Semper Fi Heating & Cooling, we provide professional leak detection and repair in Tucson for homeowners dealing with hidden pipe leaks, moisture concerns, water damage, and unexplained water use. Schedule leak detection today and get clear answers from a licensed plumbing team that knows how to track the source before recommending repairs.

Signs You Need Leak Detection

Not every leak creates a visible puddle. Some leaks happen behind walls, under cabinets, below flooring, or beneath the foundation, where damage can spread before the source is easy to see. If something feels off with your plumbing or water usage, professional leak detection can help find the problem sooner.

  • Your water bill has increased. A higher bill without a clear reason can mean water is escaping somewhere in the plumbing system.

  • You hear water running. Sounds of dripping, hissing, or running water when fixtures are off can signal an active hidden leak.

  • Walls, ceilings, or cabinets are damp. Moisture stains, bubbling paint, soft drywall, or wet cabinet bases should be checked quickly.

  • Floors feel warm or damp. Warm flooring, loose flooring, or damp carpet can be signs of a hidden pipe leak under the home.

  • Musty odors keep returning. A persistent musty smell can come from moisture trapped behind walls, under floors, or inside cabinets.

Our Leak Detection & Repair Services

Plumbing leaks can come from supply lines, fixture connections, water heaters, slab piping, drain lines, shutoff valves, or aging pipe materials. The right repair starts with finding the leak accurately instead of opening walls or flooring without a clear reason.

Semper Fi Heating & Cooling provides leak detection and repair as part of our plumbing services in Tucson, helping homeowners locate leaks, understand the damage, and choose the right repair.

Hidden Pipe Leak Detection

Leaks inside walls, ceilings, cabinets, or utility areas can create stains, odors, and structural damage before they become visible. Our plumbers look for plumbing symptoms, moisture patterns, pressure changes, and fixture behavior to narrow down the source and recommend the proper repair.

Slab Leak Detection

Many Tucson homes have slab foundations, which can make underground pipe leaks harder to identify. Warm floors, unexplained water use, foundation-area moisture, or water sounds beneath the home can all require careful evaluation. Once the source is identified, we explain repair options based on the line’s location and condition.

Fixture And Supply Line Leak Repair

Leaks around sinks, toilets, tubs, showers, shutoff valves, and appliance connections should not be ignored. Even a small drip can damage cabinets, flooring, drywall, and nearby materials over time. Our plumbers repair leaking connections, worn parts, and damaged supply lines to restore dependable plumbing.

Water Heater Leak Troubleshooting

Water near a water heater can come from the tank, valves, fittings, drain line, or nearby plumbing. We inspect the water heater and surrounding connections to determine whether the issue can be repaired or whether replacement is the safer long-term solution.

Drain Line Leak Repair

Drain leaks can create odors, stains, cabinet damage, and moisture around walls or floors. These leaks may only show up when a fixture is used, which can make them harder to spot. Our plumbers inspect the affected area, identify the leaking section, and complete the proper repair.

Our Leak Detection Process

A careful process helps reduce unnecessary damage and gives homeowners a clearer path forward. Semper Fi Heating & Cooling evaluates the symptoms, checks plumbing connections, and tracks moisture patterns before recommending repairs.

  • Symptom review. We ask about water bills, stains, odors, damp areas, water pressure changes, and when the issue first appeared.

  • Plumbing inspection. Our plumbers check visible piping, fixtures, shutoff valves, water heaters, cabinets, walls, floors, and likely leak areas.

  • Leak location. We use the symptoms and inspection findings to narrow down the source of the leak before recommending repair work.

  • Repair recommendation. Once the issue is identified, we explain what needs to be repaired and whether the problem is isolated or connected to a larger plumbing concern.

  • Final testing. After repairs are complete, we check the affected area, confirm proper plumbing operation, and review any concerns that could need further attention.

Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.

I was initially drawn to Semper Fi because I am a Marine. I became a return customer based on their prompt excellent service and fair pricing! I have purchased three A/C systems from Semper Fi and a large Hot Water Heater. They provide free service and maintenance for those units.
Make Semper Fi your first choice for your home. I will.

This is the second time we have used Semper Fi, this time for a water heater replacement. Andrew was meticulously in the removal, installation and final walk through of the replacement with us. We highly recommend Semper Fi for HVAC & plumbing.

Semper Fi was amazing to work with for our AC service and ultimately replacement. Rafael came out within the 8-11am window, thoroughly inspected the unit inside and outside and made recommendations based on our immediate needs and weighed our options to repair or replace. We ultimately went with repair and we have a crew coming out to replace our unit. If you need service, repair or replacement, we wholeheartedly recommend Semper Fi.
