What happens during a full home repipe
A full home repipe replaces aging or failing water lines throughout a house with new piping, fittings, and valves. In Baton Rouge, that usually means swapping brittle galvanized or corroded copper for PEX or Type L copper, rerouting lines for better pressure, and bringing shutoff valves up to current standards. Homeowners hear the term and picture holes everywhere and weeks without water. In practiced hands, the work is orderly, phased, and much faster than most expect. This guide explains what actually happens day by day, how crews protect finishes, and what to expect in a Baton Rouge house with slab or pier-and-beam construction. It also points out decision points the plumber will walk through, so the choices make sense rather than feel rushed.
Cajun Maintenance handles full repipes weekly across Baton Rouge, Prairieville, Denham Springs, Central, and nearby neighborhoods. The team knows where old lines hide in Goodwood ranch homes, how to route through a Shenandoah attic without softening PEX under roof heat, and how to cross a slab in Broadmoor without tearing up finished floors. This article stays practical, plain, and focused on results.
Why a full repipe comes up in Baton Rouge
Baton Rouge housing stock spans 1950s ranch houses, 70s and 80s tract neighborhoods, and newer construction with CPVC or slab leak services PEX. Galvanized steel lines from mid-century homes choke with rust and scale. Copper from the 70s may pit, especially if the home saw aggressive water or poor grounding. CPVC becomes brittle with attic heat. Those aging pipes often show the same signals: brown water after vacations, pinhole leaks at night, showers dropping to a trickle when a tap opens, and valves that snap instead of shutting off.
Water quality here accelerates certain failures. While East Baton Rouge water is well managed, temperature swings and chlorine levels still affect older systems. Attic-run lines see summer highs well over 120 degrees. In slab homes, copper embedded below concrete cannot be accessed to repair recurring slab leaks without cutting and patching floors. At a certain point, a full repipe is cleaner and cheaper than chasing leaks one at a time.
The walk-through: mapping the system before a single hole
A repipe starts with a mapped plan. The project lead walks the property and notes every fixture that needs water: kitchen sink, fridge supply, dishwasher, washing machine, water heater, hose bibs, bathrooms, and any outbuildings. The team traces the current main entry, usually near the water meter, and locates the water heater and its venting details. In Baton Rouge, many two-bath homes allow routing through the attic. Pier-and-beam homes invite crawlspace routing. Slab homes may need wall chases.
During this visit, the plumber measures fixture count, estimates runs, and photographs walls and ceilings around bathrooms and kitchens. The photos help plan cut points that avoid electrical and allow fast patching. If the home has plaster walls, the strategy may emphasize attic access to reduce patch time. If the home has shiplap or decorative tile, the plan may shift to closets or utility rooms for vertical chases to preserve finishes.
Expect a clear, written scope. It should list pipe type, fittings, main shutoff location, new angle stops at each fixture, hose bib replacements, and any code updates like thermal expansion control at the water heater. Good quotes in Baton Rouge also describe the wall repair plan: whether the plumber patches drywall to a paint-ready stage or leaves openings for a painter.
Choosing pipe: PEX vs copper for Baton Rouge homes
PEX is the most common choice today because it handles attic temperature swings, reduces fittings inside walls, and resists scale buildup. Type A PEX, used with expansion fittings, has large internal diameter for strong flow. It also tolerates minor freezing better than copper. Baton Rouge summers push attic temperatures high, but PEX is rated for those conditions when insulated and kept clear of UV and hot roof decks.
Type L copper is still used in exposed mechanical rooms, at water heater stubs, and where code or preference calls for it. Copper is rigid, which makes clean straight runs but requires more fittings to turn corners. Every fitting adds potential leak points and labor. In high-chlorine water, thin copper can develop pinholes faster, which is why Type L is preferred over Type M for longevity.
Most Baton Rouge repipes end up hybrid: PEX trunk and branches, with short copper stubs at the water heater and hose bibs. Stainless steel or brass manifolds are sometimes installed near the water heater or in an accessible closet, which allows future shutoffs by zone. A Cajun Maintenance tech will explain where manifolds help and where they add cost without value.
Permits, code, and scheduling
East Baton Rouge Parish and surrounding jurisdictions require permits for a full repipe. A licensed plumber pulls the permit, installs per IPC and local amendments, and schedules the inspection. Homeowners do not need to navigate this. The crew coordinates any water utility shutoffs and inspection windows so downtime is minimal.
Scheduling usually runs like this. For a typical 2-bath, single-story, slab-on-grade home, a repipe takes two to three working days, plus a short visit later for drywall finishing if the plumber includes patching. Larger two-story homes may run three to five days. Cajun Maintenance often stages work to keep one bathroom functional overnight when feasible, though safe water service may be off for several hours during the main tie-in.
Day 1: Protection, access, and main shutoff upgrade
The crew starts with protection. Floors are covered with runners, corner guards go on hallway edges, and plastic sheeting hangs to limit dust from access cuts. The lead confirms the plan one more time and marks access points with blue tape. The water is shut off at the street or old main valve. If the home’s main valve is unreliable, the tech replaces it at the start with a full-port ball valve. That early swap avoids surprises later.
Access points are small and strategic. Think 6 by 8 inch rectangles near the top of bathroom and kitchen walls to reach fixtures. In attics, the team lays down walkboards and moves insulation aside carefully. Baton Rouge attics can be cramped; crews start early to avoid midday heat. If the home has a crawlspace, a team member clears a perimeter and confirms safe access past HVAC lines and electrical.
The crew then caps old lines to prevent residual drips and opens the first runs for new pipe. By midday, new main trunk lines start to appear in the attic or crawlspace: one for cold and one for hot from the water heater. Plumbers drill top plates cleanly and use protective sleeves through wood. Fire blocking is respected and will be sealed when finished.
Day 2: Branch runs, fixture tie-ins, and pressure testing
The second day focuses on branches to each fixture. PEX shines here because each fixture can be a continuous run from the trunk with fewer joints. Lines are insulated where they cross attic areas, especially hot runs to showers and kitchen sinks. In a two-story home in Longwood or Oak Hills Place, vertical chases may need neat cuts inside closets for the journey between floors.
Fixtures get new angle stops. Flexible connectors are replaced, and aerators are cleaned if debris moves during testing. If the house had outdated gate valves, all change to quarter-turn ball valves. Hose bibs are upgraded with vacuum breakers, which safeguard against backflow and pass inspection.
Before the water returns, the crew pressure tests. Air or water testing is standard. At Cajun Maintenance, air testing at 60 to 80 psi for a set period is common before introducing water. Leaks show quickly at fittings, which are tightened or reworked until the test holds. After a pass, the water is slowly introduced and each line is flushed in stages to push out air and debris. Expect short bursts of cloudy water as microbubbles clear; that fades within minutes.
Day 3: Final tie-ins, water heater details, and inspection
The last main day involves clean terminations and code checks. At the water heater, the team installs new dielectric unions, a new shutoff, and often a thermal expansion tank if a closed system exists. Straps are checked for code and venting is evaluated if the unit is gas. TPR discharge piping is verified to run to an approved location. If the water heater is due for replacement soon, the plumber may suggest that swap during the repipe to avoid duplicating labor later.
Once all fixtures are live, the crew walks the home with the homeowner. Every faucet, shower, and appliance is tested for temperature and flow. The team confirms that hot arrives quickly and mixes correctly. If a bathroom had marginal pressure before, the difference is immediate. Dishwashers and fridge lines are checked for leaks after a cycle.
An inspection follows per the permit. The inspector looks for support spacing on PEX, proper pipe insulation near heaters, strapped lines where required, sealed penetrations, and correct valve types. Cajun Maintenance coordinates this visit and handles any minor punch items quickly.
Wall repair and cleanup
Small access holes are patched. If the plumber provides paint-ready patches, the drywall is taped, mudded, and sanded smooth. Texture matching in Baton Rouge homes ranges from smooth to orange peel and knockdown. Good teams spray small areas to blend the texture so a painter can finish without flashing. If a homeowner has a preferred painter, the plumber can leave openings square and ready; that reduces cost and lets a specialist match complex finishes.
The crew removes debris, vacuums dust, and rolls up floor protection. Expect a clean walk-through, not a construction zone. Most homeowners are surprised by how targeted the cuts were and how quickly water comes back in phases through the project.
How much a Baton Rouge repipe costs and why
Costs vary by footage, stories, fixture count, access difficulty, and material choice. In the Baton Rouge area, a typical 2-bath, single-story home on slab often falls in a mid four-figure to low five-figure range. A larger two-story with three or more bathrooms may push higher due to vertical chases and longer runs. Copper adds cost over PEX. Plaster walls, tight attics, or extensive tile that must be preserved can add labor.
Quotes should describe materials by name and brand, number of fixtures included, scope of valve replacements, any hose bib count, water heater work, and the level of wall repair. The cheapest estimate sometimes omits fixture stops, hose bib upgrades, or patching, which shifts cost back to the homeowner. That looks like savings at first but leads to extra hires and repeat visits. A complete scope prevents those headaches.
Baton Rouge construction quirks that affect repipes
Local construction methods influence routes. Many slab-on-grade homes route pipes through the attic to drop to fixtures. That means the plumber must protect PEX from heat and UV, keep it off hot flues, and add insulation on hot lines to reduce wait time. In pier-and-beam homes around Mid City or Old Goodwood, lines run under the house, which allows service without opening walls but requires rodent protection and secure hangers. In two-story homes in Highland or Lakeside, a vertical wet wall stacks baths, which is efficient for both plumbing and future repairs.
Hurricane season is another Baton Rouge reality. If a repipe lands near a storm forecast, crews plan around power outages or supply chain delays for fittings. Cajun Maintenance keeps common PEX sizes, ball valves, and stops stocked so projects do not stall waiting on distributors during busy storm weeks.
What changes for homeowners after a repipe
Pressure and reliability improve first. Corroded galvanized reduces flow dramatically, so new 3/4 and 1/2 inch PEX runs feel lively at taps and showers. Water runs clearer. Hidden leaks stop, so slab moisture readings drop and water bills settle. New shutoffs at each fixture give control during future repairs. A well-planned repipe often reduces temperature swings in the shower when someone flushes a toilet, because the layout uses balanced branches.
There are trade-offs to understand. PEX is quieter than copper but can transmit a soft thump if a fast-acting valve closes and there is no hammer arrestor. Plumbers add arrestors at dishwashers and washing machines where needed. Hot water wait time depends on line length and insulation. In large footprints, a recirculation solution might be worth discussing. It can be as simple as a timer pump at the water heater, or a crossover valve under the far sink. Those decisions are best made during the repipe, not later.
A quick homeowner prep checklist
- Clear under-sink cabinets and vanities the day before.
- Move fragile items from shelves near expected access points.
- Make attic access available and remove items blocking the hatch.
- Park vehicles to leave driveway space for the work van.
- Plan for a few hours without water during tie-ins.
This small list keeps the project moving and shortens downtime. Crews work more cleanly and faster when spaces are open and safe.
What Cajun Maintenance does differently on repipes
Experience in Baton Rouge neighborhoods shapes the process. The team sets realistic schedules and keeps one bathroom usable when layout allows. They use expansion PEX to maximize flow and reduce joints in hidden spaces. They insulate attic runs and avoid hot zones near flues. They swap every angle stop and supply line so weak links do not remain. They label manifolds when installed and leave a simple diagram of zones in the service folder.
Clients appreciate straight talk on finish work. Some prefer the plumber to deliver paint-ready walls. Others want their painter to handle texture and color. Cajun Maintenance quotes both ways so homeowners pick what fits timelines and budgets. That clarity limits surprises and removes friction at the end.
Red flags when comparing repipe quotes
Watch for missing valves, vague material notes, and no permit line item. If a quote says “plastic pipe” without PEX type, fitting system, and brand, that is not enough detail. If hose bibs, fridge line, and washer box are not listed, they might be skipped. If the contractor says no inspection is needed, that is incorrect for a full repipe in this market. Also be cautious if a timeline sounds unrealistically fast for a two-story home with multiple baths. Speed matters, but rushed work and poor patching lead to callbacks.
What to expect the week after
After a repipe, sediment may flush from aerators for a day or two. The plumber should show how to clean aerators and change fridge filters. Expect the crew to come back for any minor drywall touch-ups if included. If a hot water recirculation system was added, it may need a timer tweak based on household patterns. If there is any hint of air noise or a water hammer bump, the team can add small arrestors or adjust pressure regulators.
Keep a folder with the permit, inspection sign-off, pipe type, and fitting specs. This helps future service and can be a selling point if the home hits the market. Buyers in Baton Rouge respond well to “2025 full repipe with PEX Type A, new shutoffs, and inspected” in a listing.
Ready for a cleaner, stronger plumbing system
A full home repipe sounds big because it touches every room. In practice, it is a focused, phased upgrade that removes a source of ongoing stress. Done right, it protects drywall, protects floors, and gives back a house that works like it should. Baton Rouge homeowners who have lived with slow sinks or stained tubs see the change in a day.
