Slab Leak Detection and Repair in O'Fallon
Copper pipes often run under concrete slabs in O'Fallon homes. A slab leak can be particularly challenging to detect, and shifting soil can put extra stress on those pipes. Basements are common in many areas, so sump pumps and foundation drainage are an important part of keeping homes dry. We use acoustic and thermal imaging technology to locate these hidden leaks without invasive demolition. Once found, we offer direct access repair or re-routing options to fix the damaged copper section, minimizing disruption to your home.

Copper Fitting and Valve Repair in O'Fallon
Angle stops, shutoff valves and copper fittings under sinks and behind toilets can weep or seize over time. Hard water minerals build up inside valves and prevent them from closing. We replace failing valves and fittings with quarter-turn ball valves that are easier to operate. That makes future repairs and emergencies easier to manage.
Copper Pipe Joint Leak Repair in O'Fallon, MO
Leaks at pipe joints are usually due to improper soldering, fatigued connections or shifting foundations. Basements are common in many areas, so sump pumps and drain tile are an important part of keeping homes dry. Our plumbers in O'Fallon, MO carefully inspect all joints for signs of weeping or dripping. We can re-solder loose or corroded joints for a watertight seal. In cases where the joint is too damaged, we will replace the fitting and adjacent pipe sections for a secure and durable repair that meets all local plumbing codes.
Copper Pinhole Leak Repair in O'Fallon
Pinhole leaks are tiny holes that form when the inner wall of copper pipe erodes or pits. They usually appear in thin Type M pipe and on hot water lines where velocity and temperature are higher. We cut out the affected section and replace it with new Type L copper or a PEX transition. While the wall is open, we inspect nearby pipe for discoloration or thinning.
Hot Water Copper Line Repair in O'Fallon, MO
Hot water lines see more corrosion than cold lines because heat speeds up chemical reactions. Recirculation pumps that run constantly can also wear copper from the inside. We repair leaking hot lines and can adjust or add timers to your recirculation system. That reduces wear and lowers energy costs.
Preventive Copper Pipe Inspection in O'Fallon, MO
Beyond repairs, FGV Plumbing offers preventive inspections for copper piping in O'Fallon, MO homes. We can identify early signs of corrosion, stress or potential weak points before they turn into costly leaks. This proactive approach helps extend the life of your plumbing system and can save you from unexpected emergency repairs down the line, which is particularly important for homes with older copper plumbing.

Frequently Asked Questions About Copper Pipe Leak Repair in O'Fallon
The cost for copper pipe leak repair in O'Fallon varies a lot, typically ranging from $200 for a minor, accessible pinhole leak to over $2,000 for complex repairs like under-slab leaks requiring extensive work. Factors affecting cost include the leak's location, severity and the amount of pipe replacement needed. We provide transparent, upfront pricing after a full assessment.
Most simple copper pipe leak repairs, such as fixing an accessible pinhole leak or a single joint, can be completed within one to four hours. More complex issues, like leaks under a slab or extensive re-piping, may take a full day or sometimes multiple days, depending on the scope of work.
PEX resists the corrosion and scale that cause copper pinholes and is flexible and quick to install. If you have repeated copper leaks, repiping with PEX is often a cost-effective long-term solution.
Common causes include aggressive water chemistry, high water velocity, excessive pressure, poor original soldering and stray electrical current from grounding issues. These factors erode the pipe wall from the inside over time.
Common signs of a copper pipe leak include unexplained wet spots on walls, ceilings or floors, a sudden drop in water pressure, the sound of running water when no fixtures are in use, unusually high water bills or visible blue-green stains on pipes or nearby surfaces that point to corrosion.
Signs of a hidden copper pipe leak include unexplained increases in your water bill, damp spots on walls or ceilings, musty odors, the sound of running water when no fixtures are in use or visible changes in your home's foundation or landscaping. Don't ignore these indicators.
Most accessible repairs take one to two hours. Leaks inside walls or ceilings can take two to four hours, and slab leak repairs may take a whole day.
Copper pipes can leak due to several factors, including corrosion from water chemistry when the pH is too acidic or alkaline, aggressive soil conditions, high water pressure, poor installation or physical damage from foundation shifts. Groundwater from limestone areas is especially hard, which makes softeners and regular water heater flushing worthwhile. Pinhole leaks often result from long-term internal corrosion.
