Slab-on-grade construction is the norm
Most homes built through Tamarac’s 1970s and early-1980s growth sit on a concrete slab with the water lines running through it, which is exactly the layout acoustic and thermal detection are built for.
Non-invasive detection, same-day dispatch
A plumber uses acoustic listening equipment, thermal imaging and a pressure test in sequence to narrow a leak down to a location, then confirms it before anything gets opened up.
How do you find a leak you cannot see?
A hidden leak is found by narrowing, not by opening up walls at random. A plumber listens for the sound of water escaping under pressure with acoustic equipment, checks for the temperature difference wet soil or a wet slab leaves behind with a thermal camera, and isolates sections of the system with a pressure test to confirm which line is losing water. Used together, these three methods usually get the leak down to a specific spot before any drywall or flooring is touched.
That matters because the alternative, opening up a section of wall or slab to go looking, is expensive and often wrong the first time. A slab leak under a Tamarac home built in the 1970s or 1980s behaves differently than one under newer construction, so the detection method gets adjusted for what is actually under the floor before anyone reaches for a saw.
Signs to watch for
None of these prove there is a leak on their own, but together they are worth a call.
Usage climbs with no obvious change in how the house is being used.
One area of tile or slab feels noticeably warmer than the rest, often a sign of a hot-water line leaking under the floor.
With every fixture off, the meter’s leak indicator is still spinning or ticking forward.
A faint hiss or trickle you can hear but cannot locate, usually loudest late at night when the house is quiet.
Why this matters here
What the age and layout of a Tamarac home changes about finding a leak.
Most homes built through Tamarac’s 1970s and early-1980s growth sit on a concrete slab with the water lines running through it, which is exactly the layout acoustic and thermal detection are built for.
Homes from that era commonly ran copper supply lines, and a pinhole leak in aging copper can be pinpoint-small and still lose a meaningful amount of water a day.
In neighborhoods built around lakes and canals, a wet patch of yard is not automatically a plumbing leak: irrigation and drainage get ruled out first so a slab is never opened on a guess.
Questions
Usually not to find it. Acoustic, thermal and pressure methods narrow the location first, so cutting is limited to the confirmed spot when repair actually starts.
A warm patch of floor, a hot water heater that runs constantly, or a rising water bill with no other explanation are the usual signs; call and describe what you are seeing.
A slow leak can usually be scheduled, but call anyway: the same team handles both, and it is worth ruling out anything urgent.
Both. Detection and repair are handled by the same visit whenever the fix is straightforward once the leak is located.
It happens more than you would think in a neighborhood with lawn irrigation. Detection includes ruling that out before any interior line is suspected.
Do not wait for it to surface
A hidden leak rarely gets cheaper by waiting. Call and describe what you are seeing.
No obligation. A short call is often enough to tell you whether it can wait.
