San Jose’s plumbing has a personality. It’s a mix of 1950s ranch homes with galvanized lines, revamped Eichlers with radiant floor heating, tech campuses with miles of copper and PEX, and new infill projects built to the latest code. All of them share a truth that never makes the real estate flyer: water finds a way out. Sometimes it’s a pinhole whispering through an attic line, sometimes it’s a slow seep under a slab, and sometimes it’s a midnight burst behind a washing machine. That’s where a seasoned, local crew matters. JB Rooter and Plumbing has spent years in crawlspaces, mechanical rooms, and front yards across the South Bay, solving pipe leak repair with patience, proper diagnostics, and workmanship that holds up when the water turns back on.
Not all leaks show themselves with a dramatic puddle. More often, they hint. You might notice an unexplained spike in a water bill, a warm stripe across a section of slab, or the faint sound of hissing in the wall when everything is shut off. In older Willow Glen homes with galvanized steel, corrosion inside the pipe narrows the flow until it finally pocks through from the inside. In Cambrian and Blossom Valley, copper pinholes from aggressive water chemistry and tiny imperfections along the top of hot water lines show up after 15 to 25 years. Newer condos with PEX haven’t escaped entirely either, especially at fittings that were rushed during construction or stressed by UV exposure during installation.
San Jose’s soil also plays a role. In the Alum Rock foothills, expansive clay moves as seasons change, stressing buried service lines and sewer laterals. That movement can crack joints and introduce slow leaks that saturate soil without a surface sign for months. We’ve traced leaks that only appeared as a patch of greener lawn above a broken irrigation tie-in, and others that triggered mold in a hall closet two rooms away from the actual source.
Experience helps, but tools keep us honest. Before anyone lifts a saw, we confirm.
A quick example: A homeowner near Santana Row called about a “ghost leak.” No visible water, but the meter spun. Hot water recirculation was installed without a check valve, causing heat migration that fooled the occupants. Isolation testing found the leak in the upstairs guest bath wall, not the slab. We opened a 10 by 12 inch section, repaired a pinholed 1/2 inch copper elbow, insulated properly, and closed up. The tile and vanity stayed untouched.
Pipe leak repair is not one-size-fits-all. Patching the hole that presents itself can be a bandage, but if the pipe material has reached the end of its service life, replacements save money and headaches. We walk clients through options and trade-offs, with costs and timelines that reflect reality in San Jose.
Spot repairs in accessible areas: For a single pinhole in an accessible wall or crawlspace, we cut back to clean, sound pipe and sweat in new copper, or install a crimped PEX section if the system is already PEX. We avoid push-fit fittings in concealed spaces unless circumstances make them the only safe choice, preferring permanent, code-compliant joints. This type of repair usually takes 1 to 3 hours.
Slab leaks: The classic Bay Area headache. You can break the slab, expose the line, and fix it at the breach. That often makes sense for a line that is otherwise healthy and for homes where a direct route prevents large-scale demo. On older copper embedded in concrete, rerouting overhead is frequently smarter. We cap the failed line at both ends and run new PEX or copper through walls and jb rooter and plumbing communication ceilings, then repair drywall rather than jackhammering floors. Overhead reroutes typically take one to two days and allow the home to stay livable.
Repipes: When we see multiple pinholes within a short timeframe, repiping turns into the cost-effective path. A whole-home PEX repipe in a 2 bath ranch often completes in 2 to 4 days, with water off in short windows and patch-ready walls when we’re done. Copper remains a fine choice in certain scenarios, especially for exposed runs and where a homeowner wants a specific material. We discuss water chemistry and existing fixtures before recommending a route.
Exterior service line leaks: From the meter to the house, older galvanized or thin-wall copper lines can fail at unions and under driveways. Trenchless methods let us replace that line with high-density polyethylene (HDPE) or copper without excavating the entire yard. We expose at each end, pull the new line, pressure test, backfill, and restore the surface cleanly.
We’re decisive about valves as well. If we open a wall and find a gate valve that doesn’t close, we replace it with a quarter-turn ball valve. It’s a modest addition that pays off the next time someone needs to isolate a fixture without shutting down the whole house.
Permitting expectations, soil conditions, and fixture trends vary by city. San Jose inspectors are thorough about seismic strapping on water heaters, vacuum breakers on hose bibbs, and proper support spacing for PEX and copper. We build to those expectations because we work under them every week. We also know the neighborhoods where polybutylene still pops up in townhomes, which bathrooms are stacked in typical floor plans, and how long it really takes to dry out a saturated plaster wall in a Rose Garden bungalow. That familiarity shortens the path from problem to solution.
Leaks keep their own schedule, which is why people search for a 24 hour plumber near me at 2 a.m. We maintain an on-call rotation to handle true emergencies. If a supply line bursts, we guide you to the main shutoff by phone, then arrive ready to stabilize. Emergency plumbing repair is about the first hour as much as the fix. We carry a range of fittings, caps, and temporary valves to stop the water and protect the structure. If drying equipment is needed, we coordinate with restoration partners so that mitigation starts immediately, not two days later.
Affordable plumbing repair doesn’t mean cutting corners. It means prioritizing actions that prevent secondary damage. A simple example is swapping a braided stainless steel supply line for a swollen rubber hose while we’re on site. It adds minutes, saves the next call.
While leak response is a big part of our world, prevention and upkeep carry the real value over time. Many calls that start as pipe leak repair come from upstream issues we can solve.
Drain cleaning services: Slow drains set the stage for overflows that saturate cabinets and floors. We cable lines to remove roots and debris, then recommend hydro jet drain cleaning when we see grease or scale lining the pipe. For restaurants and commercial kitchens in San Jose, scheduled jetting reduces emergency nights to almost zero.
Sewer line repair and trenchless sewer replacement: A broken sewer can mimic a fresh water leak by softening soil and raising a utility bill if irrigation compensates for the mess. We camera lines to assess breaks, bellies, and root intrusion. When replacement is required, trenchless methods minimize landscape damage and shorten the timeline to a single day in many cases.
Water heater installation: Leaks near a water heater could be a failed tank, a sweating TPR valve, or a pinhole above. We determine the source and provide options for tank or tankless. Proper pan drains, expansion tanks, and seismic strapping are standard in our installs, keeping code officials and homeowners happy.
Toilet installation and repair: A wobbly toilet with a compromised wax ring can leak into the subfloor for months. We reset with new seals, address flange height, and replace angle stops that no longer shut off. If a hairline crack in the tank is to blame, we’ll help you choose a reliable replacement that matches rough-in and seat height.
Kitchen plumbing services and bathroom plumbing repair: Under-sink leaks, garbage disposal failures, shower valve drips, and supply riser issues are all common culprits. We fix the problem, then look upstream at pressure, water hammer, and outdated shutoffs that can transform a drip into a flood.
Plumbing maintenance services: Small checkups beat large bills. Annual pressure tests, meter checks, and visual inspections of exposed lines and valves catch trouble early. For commercial clients, we tailor maintenance to occupancy and business hours, quietly reducing downtime.
A downtown condo with a leak is not the same as a light industrial shop or a school. As a local plumbing company that works both sides, we adapt.
Residential plumbing services: We respect the home. Shoe covers, drop cloths, and daily cleanups are muscle memory. We communicate when water will be off, we store materials out of reach of children and pets, and we leave walls patch-ready with clear notes for your painter. On multi-day projects, we keep a functioning bathroom whenever possible.
Commercial plumbing contractor services: Offices, retail spaces, and campuses expect predictability. We coordinate with facility managers, provide clear scopes, and stage work after hours when needed. For tenant improvements, we document as-builts so future maintenance isn’t guesswork. Preventive jetting programs, backflow testing, and fixture upgrades reduce surprise outages.
Clients often ask whether copper is still worth it, or if PEX is reliable. Both can be excellent when installed correctly, and both can fail when misused. Copper thrives with proper water chemistry, correct support, and protection from abrasive contact in concrete. PEX shines in remodels and repipes thanks to flexible routing, fewer fittings, and fast installation. The weak link is usually a fitting or a rushed step. We choose crimp systems with proven track records, avoid UV exposure during staging, and pressure test before closing walls. Where we transition from one material to another, we use listed dielectric unions to prevent galvanic corrosion.
Sealants matter too. On threaded connections we pick the right thread sealant or PTFE tape layering based on fluid, temperature, and code. On sweated copper, we clean aggressively, flux appropriately, and avoid overheating that can anneal pipe and weaken the joint. These small choices add up to systems that behave for decades.
Nobody enjoys surprises except at birthday parties. When we assess a leak, we outline at least two paths whenever possible. For example, a spot repair behind a laundry room may run a few hundred dollars and take two hours. An overhead reroute for a slab leak might be in the low four figures and require wall access in three rooms. We explain what’s visible, what’s assumed, and what might change if we find hidden issues. If pipe condition suggests repeated failures, we show numbers for a repipe with the value difference over three to five years. Many homeowners decide a repipe becomes the affordable route when viewed against multiple emergency call-outs and patchwork.
Permits and inspection fees are included in our estimates when required. We pull the permit, schedule the inspection, and meet the officer on site. In San Jose, inspection timelines are reasonable, but we plan work sequences to keep your home functional while we wait.
Not every drip requires a same-day visit, but some do. A small bead on a compression joint under a sink might be monitored for a day if you can place a bowl and shutwater is accessible. A musty smell behind a wall, warm floors, or a meter that spins when no fixtures are open deserve prompt attention. If you hear hissing with fixtures closed, shut off the main and call. That simple move can prevent thousands in damage.
For businesses, recurring backups, damp spots in landscaping near lateral runs, or toilets that bubble when nearby sinks drain are early warnings of sewer issues. Addressing them with camera inspection and hydro jetting usually prevents weekend emergencies that disrupt operations.
Being local and licensed helps, but it’s the way we show up that keeps clients. We answer phones with people, not menus. We give arrival windows that reflect Bay Area traffic, and we call if a job runs long. Our techs explain what they’re doing and why. If the best fix is modest and you could do it yourself safely, we’ll say so. That honesty earns the next call when the job requires a professional.
“Trusted plumbing repair” isn’t a slogan, it’s the accumulation of small choices during every visit. Wiping solder drips, labeling new shutoffs, taking a minute to adjust a misaligned cabinet door we removed, bringing doorstops so heavy gear doesn’t scar trim. Those details aren’t billable line items. They’re how we’d want someone to treat our own homes.
San Jose water is generally good, but it varies by zone and season. High static pressure, often above 80 psi, is a quiet leak accelerant. It stresses washers, valves, and supply lines. If we measure high pressure at your hose bibb, we recommend a pressure reducing valve and gauge set at 55 to 65 psi. That modest change extends the life of everything downstream, from cartridges to ice makers.
Hardness contributes to scale inside pipes and fixtures. For tank water heaters, sediment flushes keep tanks efficient and reduce overheating at the lower third. For tankless units, periodic descaling protects the heat exchanger. Those simple maintenance steps head off leaks caused by overheating and scale-induced strain.
A lot of leak work intersects insurance. We document the damage with photos and notes, provide clear invoices that separate mitigation from repair, and communicate with adjusters when asked. If demo is necessary, we take care to remove only what’s needed and we protect adjacent finishes. For drying, we set expectations on noise and duration. Most small water events dry in 2 to 4 days with air movement and dehumidification. We time our return visit for permanent repairs to align with the end of mitigation, so you aren’t staring at open walls any jb rooter longer than necessary.
For homeowners and property managers who want fewer surprises, we offer simple maintenance plans. Annual whole-home checks include visible leak inspection, meter and pressure tests, water heater assessment, valve exercises, and quick fixes like tightening packing nuts or replacing worn supply lines. For multifamily buildings and offices, we bundle drain cleaning services and camera inspections. Catching a sweating shutoff or a bulging hose during a routine visit saves the midnight call and the soaked baseboard.
We respect capable homeowners. Replacing a faucet supply line or tightening a compression nut is fair game if you’re comfortable and can isolate water quickly. Where we urge caution is anything jb rooter and plumbing expert services behind walls, under slabs, or connected to gas and water heaters. We’ve been called after a well-intentioned solder joint scorched a stud bay, and after a push-fit fitting on a hot recirculation loop let go overnight. If you’re unsure, send a photo when you call. We’ll tell you whether to wait for us or get the channel-lock pliers.
