Slab Leak Detection in Glendale — Non-Invasive, Same Day
Wet floors with no visible source, a water bill that won't stop climbing, running water you can't find — these are slab leak signs. We find it without tearing up your floor first.
The 43rd Avenue corridor and downtown Glendale have some of the oldest residential construction in the west valley — 1960s and 1970s homes where original copper pipe has been running hard water for 50–60 years. Slab leak detection and repiping are among our most common services in this part of Glendale.
Glendale's mix of older midcentury homes and 1980s-1990s construction puts a lot of properties in the slab leak risk window. Areas around Arrowhead and the older downtown core both see regular calls for repiping and slab leak detection. We serve the full city from 43rd Avenue west through Arrowhead Ranch.
Signs You Have a Slab Leak in Glendale
- Your water bill has been rising with no explanation
- You hear water running when every fixture in the house is off
- Warm or hot spots on your floor — especially tile or concrete
- Wet, damp, or soft spots in flooring, carpet, or drywall at floor level
- Visible floor cracks or mounding, especially along a line
- Reduced water pressure throughout the house
- Mold or mildew smell coming from flooring or baseboards
Any one of these signs in a home built before 2000 in Glendale should be investigated promptly. Slab leaks do not get better on their own — they get worse. Water migration under the slab can cause foundation movement, mold growth, and significant structural damage if left unaddressed.
How We Find Slab Leaks Without Tearing Up Your Floor
We use electronic amplification equipment — ground microphones and acoustic listening devices — to detect the sound of water escaping from the pipe below the slab. Combined with thermal imaging that identifies temperature differentials in the floor surface, we can locate the leak to within a few inches without any demolition.
We only open the floor after we know exactly where the leak is. The typical detection visit involves no excavation — we locate, mark, explain what we found, and then present your repair options with pricing before any work begins.
Slab Leak Repair Options and Cost
Spot repair — We open the slab at the identified leak point, repair or replace the damaged section, and patch the concrete. Best when the surrounding pipe is in good condition and the leak is isolated. Cost: typically $500–$1,500.
Pipe rerouting — We bypass the under-slab section entirely, running a new supply line through your walls or ceiling. No excavation required. Best when the under-slab pipe is aging or the leak location is difficult to access. Cost: typically $1,500–$3,500.
Full repipe — When inspection reveals that the slab leak is one of several failing points in an aging copper system, repiping the whole house addresses the root cause rather than chasing individual leaks. We walk through all options honestly and let you make the call.
We offer financing starting at $41/month for qualifying slab leak and repipe projects. We give you the exact number before we start.
Frequently Asked Questions
Detection typically runs $150–$350 depending on the size of the home and complexity of the plumbing layout. We use non-invasive electronic listening equipment and thermal imaging before recommending any excavation. If we detect a leak, repair cost depends on the repair method — spot repair typically runs $500–$1,500; rerouting a line runs $1,500–$3,500+. We give you the exact number before we start.
The most common signs are unexplained increases in your water bill, the sound of running water when everything is turned off, warm or wet spots on the floor, reduced water pressure throughout the house, and visible cracks or settling in flooring. In Glendale's hard water environment, these signs in a home built before 2000 should be taken seriously and inspected promptly.
Often, yes. The two most common non-invasive approaches are pipe rerouting (running a new supply line through the walls or ceiling, bypassing the under-slab section entirely) and epoxy pipe lining (coating the inside of the existing pipe to seal the leak). Whether one of these approaches is right depends on the location of the leak, the condition of the surrounding pipe, and the age of your plumbing system overall. We'll explain all options before any work begins.
Detection is typically completed in 2–4 hours. A spot repair or pipe reroute generally takes one full day. Full repipe projects — when the inspection reveals the whole system needs replacement — typically take 2–3 days. We work to minimize disruption and keep your home livable throughout the process.
Many standard homeowners policies cover sudden and accidental water damage from a slab leak — but coverage varies significantly by policy. Some cover only the resulting damage, not the repair itself. We recommend calling your insurance company before repair begins, and we can provide the documentation most insurers require. We work with insurance claims regularly.
