What is Repiping?
Repiping is the process of removing old, corroded, or failing pipes from your home and replacing them with new, code-compliant piping materials. Unlike a single pipe repair that addresses one isolated problem, a repipe replaces all — or a significant portion — of the water supply lines, drain lines, sewer lines, or gas lines running throughout your property.
A full repipe typically involves:
Shutting off water or gas supply to the affected system
Removing or bypassing deteriorated pipes inside walls, under floors, and through crawl spaces
Installing new piping (copper, PEX, or other approved materials) throughout the home
Pressure testing the new system to verify integrity and performance
Patching drywall and access points opened during installation
Final inspection to confirm the work meets local building codes
Most residential repipes in Los Altos can be completed within 2 to 5 days, depending on the size of the home, the scope of work, and the materials selected. Throughout the project, our team works to maintain partial water access so you can remain in your home comfortably.
Pro Tip: If your Los Altos home has never been repiped and was built before 1980, schedule a free camera inspection with Drain & Water — even if you haven’t noticed symptoms yet. Many pipe failures start inside the walls where you can’t see them until significant damage has already occurred.
Los Altos' Trusted Repiping Specialists
Repiping Services We Offer in Los Altos
At Drain & Water, we don’t take a one-size-fits-all approach. Different pipe systems in your home serve different purposes, and each requires a tailored repiping strategy. Here are the repiping services we provide to Los Altos homeowners:
Sewer Line Repipe
If your main sewer line is cracked, collapsed, or infiltrated by tree roots, a full sewer line repipe restores proper waste flow from your home to the city main. We offer both traditional and trenchless sewer line solutions to minimize disruption to your landscaping and driveway.
Gas Line Repipe
Aging or corroded gas lines pose serious safety risks, including gas leaks and carbon monoxide exposure. Our licensed technicians (C36 classification) repipe gas lines serving furnaces, water heaters, stoves, dryers, outdoor BBQs, and fire features to current California safety codes. Learn more about our gas line services.
Drain Line Repipe
Persistent slow drains, recurring backups, and foul odors may indicate deteriorating drain lines. A drain line replacement removes the failing pipe entirely and installs new, properly graded drain piping for long-term reliability.
Copper Repipe
Copper piping remains the gold standard for residential water supply lines. It’s durable, bacteria-resistant, and has a proven lifespan of 50 to 70+ years. Copper is ideal for Los Altos homeowners who want a premium, long-lasting solution.
PEX Repipe
PEX (cross-linked polyethylene) is a flexible, corrosion-resistant piping material that is excellent for retrofits and older homes where running rigid pipe is difficult. PEX resists scale and chlorine buildup, installs faster than copper, and has an expected lifespan of 40 to 50 years.
Whole Home Repipe
A whole home repipe replaces every water supply line in your home — both hot and cold — from the main shutoff valve to every fixture. This is the most comprehensive solution for homes with widespread pipe deterioration and is often the most cost-effective long-term investment.
Pro Tip: If you’re planning a kitchen or bathroom remodel in your Los Altos home, it’s the ideal time to repipe. Walls are already open, which reduces labor time and drywall repair costs. Ask our team about bundling a repipe with your renovation project.

Low Water Pressure at Multiple Fixtures
A gradual decline in water pressure throughout the house often points to internal pipe corrosion and mineral buildup restricting flow. If the pressure drops when multiple fixtures run simultaneously, deteriorating pipes are a likely cause.
Rust-Colored or Discolored Water
Brown, yellow, or reddish water coming from your faucets is one of the clearest indicators of corroding pipes — particularly galvanized steel lines common in older homes.
Recurring Pinhole Leaks
A single pinhole leak is a warning. Two or more pinhole leaks in different locations signal systemic pipe failure — patching individual spots won’t solve the underlying corrosion happening throughout the system.
Visible Corrosion on Exposed Pipes
Green, white, or bluish mineral deposits on pipes under sinks, in crawl spaces, or in your garage indicate active corrosion and imminent failure risk.
Water temperature fluctuations
If your shower goes cold unexpectedly or takes a long time to heat up, corroded pipes may be restricting hot water flow.
Frequent Plumbing Repairs
If you’re calling a plumber multiple times a year for leaks, clogs, or water quality issues, the cost of repeated repairs often exceeds the investment in a full repipe.
Banging, Rattling, or Noisy Pipes
Unusual sounds when you turn water on or off can indicate pressure irregularities, loose fittings, or deteriorating pipe sections within your walls.
Your Home Was Built Before 1985 and Has Never Been Repiped
Pipes from this era are at or past their expected service life. A proactive inspection is strongly recommended.
Strange Tastes or Odors in Your Water
Metallic, earthy, or unpleasant tastes and smells can come from rust, sediment, or bacterial growth inside deteriorating pipes.
Common Signs It May Be Time for a Repiping
Many Los Altos homes were built during the mid-century building boom of the 1950s and 1960s, which means their original galvanized steel or early copper plumbing has been in service for 60 to 70+ years. Here are the warning signs that indicate your home may need a repipe.
Pro Tip: Don’t wait for a catastrophic pipe burst to act. Water damage from a failed pipe can cost thousands in repairs to flooring, drywall, and personal belongings. A proactive repipe is always less expensive than emergency water damage restoration. Schedule a leak detection inspection with Drain & Water to assess your system’s condition.

Recommended Piping Materials for Los Altos Homes
Choosing the right pipe material is one of the most important decisions during a repipe. Here’s what we recommend based on our experience serving Los Altos properties:
Copper (Type L)
Best for: Long-term reliability and premium home applications
Lifespan: 50–70+ years
Advantages: Extremely durable, naturally bacteria-resistant, recyclable, and proven performance in Bay Area water conditions
Considerations: Higher material cost than PEX; rigid installation requires more access points
Our recommendation: Ideal for Los Altos homeowners who want the longest-lasting solution and aren’t concerned about upfront material costs
PEX (Cross-Linked Polyethylene)
Best for: Retrofits, renovations, and homes with tight or hard-to-access pipe routes
Lifespan: 40–50 years
Advantages: Flexible, freeze-resistant, corrosion-proof, resists scale and chlorine buildup, faster installation
Considerations: Cannot be used outdoors or in direct UV exposure
Our recommendation: Excellent choice for most Los Altos homes, especially older properties where minimizing drywall cuts and wall access is a priority
CPVC (Chlorinated Polyvinyl Chloride)
Best for: Budget-conscious hot and cold water supply lines
Lifespan: 40–50 years
Advantages: Affordable, corrosion-resistant, handles hot water well
Considerations: Can become brittle over time; less flexible than PEX
Materials We Replace:
Galvanized steel — Prone to internal rust, corrosion, and lead contamination. Common in Los Altos homes built before the 1970s. Should always be fully replaced.
Polybutylene — A plastic pipe used from the late 1970s through the 1990s that is highly prone to sudden failure. Replacement is strongly recommended.
Pro Tip: If you’re unsure which piping material is right for your home, our technicians will evaluate your water pressure, pipe accessibility, local code requirements, and your budget before making a recommendation. There’s no one-size-fits-all answer — the right material depends on your home’s unique layout and your priorities.

Our Repiping Process
At Drain & Water, we follow a structured process on every repipe project to ensure quality, transparency, and minimal disruption to your daily life.
Step 1: Free Consultation & Inspection
We start with an on-site evaluation of your plumbing system. Our technician inspects exposed pipes, tests water pressure, checks water quality, and performs a video camera inspection of your drain and sewer lines to assess the full picture.
Step 2: Detailed Estimate & Material Recommendation
You’ll receive a written, itemized estimate that includes the recommended pipe material, scope of work, timeline, and total cost. We explain every line item and answer every question before any work begins.
Step 3: Permit & Scheduling
Repiping in Los Altos requires a plumbing permit from the City of Los Altos Building Division. California’s Contractors State License Board requires licensed contractors to pull permits for plumbing work of this scope. Drain & Water handles the permit application on your behalf so you don’t have to visit the building department.
Step 4: Pipe Installation
Our licensed technicians remove or bypass old piping and install new supply lines, drain lines, or gas lines throughout the designated areas. We protect your flooring, cabinetry, and finishes throughout the process, and we restore partial water access at the end of each workday so you’re never without water overnight.
Step 5: Pressure Testing & Inspection
After installation, we pressure test the entire new system to verify there are no leaks or weak points. A city inspector then reviews the completed work to confirm it meets all current California plumbing codes.
Step 6: Drywall Patching & Cleanup
We patch all drywall access points created during the repipe and leave your home clean. Our goal is to leave your property looking as good as — or better than — when we arrived.
Step 7: Warranty & Follow-Up
Every qualifying repipe receives our Limited Lifetime Warranty on workmanship. We also provide follow-up support and are available for any questions after the project is complete.

What Los Altos Homeowners Should Know Before Preparing for a Full Repipe
A whole home repipe is a significant but manageable project. Here’s what to prepare for:
Expect Some Wall Openings
Technicians need access points in walls and ceilings to remove old pipes and install new ones. All access holes are patched after the work is complete, but you may want to plan for touch-up painting afterward.
Clear Access to Pipes
Before your repipe appointment, clear items from under sinks, move furniture away from walls where pipes run, and ensure your water heater and main shutoff valve are accessible. This helps our crew work efficiently and protects your belongings.
Water Will Be Off During Work Hours
Water service is typically interrupted during the workday while installation is in progress. We restore water access each evening so you can cook, shower, and use plumbing overnight.
Permits Are Non-Negotiable
The City of Los Altos requires plumbing permits for repiping work. Drain & Water pulls all necessary permits and schedules inspections on your behalf — you don’t need to visit city hall.
Plan Around Your Schedule
Most residential repipes take 2 to 5 days. If you work from home, let your technician know so we can plan pipe access in a way that minimizes disruption to your workspace.
Pro Tip: Ask your Drain & Water technician for a pre-repipe checklist specific to your home’s layout. Every home is different, and a customized preparation plan ensures the smoothest possible experience.
Pro Tip: If your home has older water heater equipment, a repipe is an ideal time to evaluate whether your water heater should also be replaced. Bundling both services can save time, reduce total labor costs, and ensure your entire plumbing system is updated at once.
Frequently Asked Questions About Repiping Services in Los Altos
How long does a whole home repipe take in Los Altos?
Most residential repipes in Los Altos are completed within 2 to 5 business days, depending on the size of the home, number of fixtures, pipe material selected, and accessibility. Our team works efficiently to minimize disruption and restores water service each evening.
What pipe materials do you recommend for Los Altos homes?
We primarily recommend copper (Type L) and PEX for residential repipes. Copper offers the longest lifespan at 50–70+ years and is ideal for homeowners who prioritize durability. PEX is excellent for retrofits, offers 40–50 years of service, and installs faster with less wall access needed.
Do I need a permit to repipe my home in Los Altos?
Yes. The City of Los Altos requires a plumbing permit for whole-home repiping and significant pipe replacement work. Drain & Water handles the entire permit process on your behalf, including the application and scheduling the required inspection.
Will I need to leave my home during the repipe?
In most cases, no. We plan the installation in stages to maintain partial water access during the project. Water is typically shut off during working hours and restored each evening so you can continue living in your home comfortably.
How do I know if I need a full repipe or just a repair?
If you’re experiencing isolated issues — a single leak, one slow drain — a targeted repair may be sufficient. However, if you’re dealing with multiple leaks, widespread low pressure, discolored water, or your home has galvanized steel pipes, a full repipe is typically the more reliable and cost-effective long-term solution.
Does Drain & Water repipe both water lines and sewer lines?
Yes. We provide comprehensive repiping services for water supply lines, sewer lines, drain lines, and gas lines. We also offer trenchless methods for underground pipe replacement to reduce excavation.
What warranty do you offer on repiping work?
Drain & Water backs qualifying repipe work with a Limited Lifetime Warranty on workmanship. This means if there is ever an issue related to our installation, we’ll make it right — giving you long-term peace of mind and confidence in your investment.
