Water stain on the ceiling? Spike in your water bill? We track down hidden leaks fast — then fix them for good, whether that means a simple pipe repair or a full repipe of your home's aging plumbing.
Galvanized steel was the pipe of choice when most Fairfax County neighborhoods were built, and after forty to sixty years of service those pipes do not just leak at joints, they corrode from the inside until the walls are paper-thin. We have opened up walls in Springfield, Burke, and Centreville homes to find galvanized pipes so deteriorated that a firm grip could crush them. The Fairfax Water system's moderate hardness of six to eight grains per gallon accelerates internal scale buildup, and once that scale starts flaking it clogs valves and fixtures downstream of the leak you called about.
Fairfax County's housing boom predated the widespread adoption of copper and PEX, leaving thousands of homes still reliant on original galvanized lines that are well past their expected service life. Leak repair in these homes almost always leads to a broader conversation about whole-house repiping, which is a conversation worth having before the next failure happens inside a finished wall.
Galvanized steel supply pipes original to Fairfax County's mid-century and 1970s housing stock develop pinhole leaks behind walls, often undetected until mold or staining appears on the finished surface.
Slab-on-grade homes in parts of Springfield and Lorton experience copper supply line failures beneath the foundation, where soil chemicals and slight foundation movement stress soldered joints over decades.
Fairfax Water's moderate mineral content creates interior scale in older pipes that eventually restricts flow enough to cause pressure drops at the furthest fixtures, masking the real problem of deteriorating pipe walls.

“Max did such a great job with the install of our Cloud RO system. He was efficient and explained everything very clearly. This was a system that we purchased and hired Pioneer to install for us. Max had experience with installing this system specifically and was very positive and knowledgeable. He was even so kind as to take the boxes out for us. It was nice to just have it all taken care of in a matter of an hour by a professional. Highly recommend!”

Small plumbing problems don't stay small. A dripping faucet wastes 3,000 gallons a year. A slow drain becomes a sewage backup. A pinhole leak behind your wall becomes mold and drywall damage.
