Leak Detection and Repair in McHenry, IL
A ceiling stain under a bathroom, a warm spot on the floor or a water bill that keeps climbing. We find hidden leaks before opening anything, fix them and give you a flat price first. From our office on West Elm Street.
Signs of a Hidden Leak
Watch for:
A Stain Under a Bathroom
Often a shower valve, drain seal or toilet leaking into the ceiling below.
A Warm or Damp Floor
A hot water line leaking under the floor or slab.
A Higher Water Bill
Or, on a well, a pump that cycles when nothing is running.
A Musty Smell
Hidden moisture often smells before it shows.
Leaks We Find and Repair
From fixtures to buried lines:
Bathroom Leaks
Shower valves, drain seals, toilets and supply lines.
Pipes in Walls and Floors
Copper pinholes, failed fittings and corroded pipe.
Slab and Underground Lines
Leaks under a slab or between the meter or well and the house.
Repiping
When pipe is failing in several places, we replace it.
Leaks in McHenry Homes
Where leaks start in McHenry has a lot to do with the water and the age of the house.
Hard Water Wears Valves and Fittings
Scale stiffens valves and wears seals, so drips start at fixtures and shutoffs sooner.
Pinholes in Older Copper
In homes from the 1970s and 1980s, some copper lines develop pinhole leaks, especially near fittings.
Well Pumps That Never Rest
On a private well, a pressure tank or pump that cycles with no water running often means a leak somewhere.
Seasonal Homes
Some lake-area homes sit empty part of the year. A small leak can run for weeks before anyone notices.
