We start every faucet job with a pressure test and visual check of the supply lines and shutoff valves. In homes built in Downtown Gaithersburg and Kentlands we often find mineral buildup from the local water combined with seasonal temperature swings that expand and contract metal parts. We use basin wrenches and seat wrenches to remove stems without damaging the fixture body. Montgomery County code requires proper shutoff access so we verify that before any disassembly.
After identifying the failure we replace worn cartridges or compression seats with parts rated for the local supply pressure. Humid summers accelerate corrosion on exposed brass while winter freezes can crack internal components in unheated utility rooms. We carry common Moen and Delta cartridges on the truck to finish most repairs in one visit. Final steps include leak testing under full pressure and restoring water flow to confirm no drips remain at the spout or handles.
