Find and repair visible or hidden plumbing leaks before they cause larger property damage.
Leak Detection and Repair is a professional service service for residential and commercial plumbing or mechanical systems. Tandem Mechanical evaluates the existing condition, identifies the actual problem or installation requirement, explains the available options and completes the approved scope with testing afterward.
Exactly what we do, what you get, and what to expect — answered the way a careful customer would ask.
Expected duration: 1-2 hours for a leak at an accessible location (exposed basement piping, under-sink supply lines, water heater connections). 2-4 hours if the leak is concealed behind finished walls or ceilings and requires diagnostic work to locate followed by access and repair. More complex situations involving multiple leak points or difficult access may require a longer visit or a follow-up appointment.
Workmanship on leak repairs is guaranteed — if the repaired location re-leaks due to the quality of our repair work, we will return to address it at no additional labor charge. Manufacturer warranties apply to any replacement parts or fittings installed. Note that a workmanship warranty covers the specific repair performed; it does not cover new or unrelated failures that develop elsewhere in the system after the visit.
Professional service covering the full scope of leak detection and repair needs.
Repair of accessible leaking piping, valves, fixture connections, and related plumbing.
Diagnostic evaluation of water stains, moisture, pressure changes, and other concealed-leak symptoms.
Recommendations when repeated leaks indicate a larger piping-condition problem.
If you're experiencing any of these issues, a technician can diagnose the problem and recommend the right solution.
Our first job is to diagnose the problem. We do not assume a failed system automatically needs replacement.
A leaking water heater should be inspected quickly. Leaks can come from connections, valves, corrosion, tank failure, pressure issues, or other system problems. In some cases, repair may be possible. In other cases, replacement may be the safer and more reliable option. For older or repeatedly failing piping systems, pipe repair and repiping services may be the right long-term solution.
If replacement is the practical choice, qualifying installation financing may be available. Subject to approval.
Pipe leaks can happen because of age, corrosion, freezing, pressure issues, poor connections, or damaged materials. Some pipe leaks are visible right away, while others remain hidden until water damage appears.
Toilets, sinks, faucets, garbage disposals, dishwashers, washing machines, and supply lines can all leak if parts wear out, connections loosen, or installation issues occur.
Leaking water heaters should be inspected quickly. Leaks can come from connections, valves, corrosion, tank failure, pressure issues, or other system problems.
Slow drains, sewer backups, floor drain overflows, and clogged lines can create water damage and sanitation concerns.
Hard water, minerals, corrosion, sediment, and pressure issues can contribute to fixture wear, pipe problems, and recurring plumbing concerns. Water softeners and filtration systems can support better long-term plumbing performance.
Garbage disposals, dishwashers, washing machines, and supply lines can leak if parts wear out, connections loosen, or installation issues occur.

Residential leak service covers kitchens, bathrooms, basements, utility areas, water heaters, fixture connections, and accessible supply piping.
Commercial leak work is coordinated around occupied spaces, equipment, tenants, and property operations so the affected system can be isolated and repaired with appropriate planning.
Leak diagnosis depends on access, piping material, location, whether the leak is active or intermittent, pressure conditions, and the amount of visible evidence. Some concealed leaks require staged access to confirm the exact source.
Address small leaks early. Watch for staining, corrosion, recurring moisture, or unexplained water use, and replace failing valves or supply connections before they cause larger damage.
Leak detection and repair are available throughout Tandem Mechanical's active service area for residential and commercial plumbing systems.
