When aging pipes threaten the safety, comfort, and value of your multi-family property, you need a repiping partner who understands the complexities of occupied buildings. We Do Repipes delivers multi-family repipe Houston solutions for apartment complexes, condominiums, townhome communities, and duplexes across the Greater Houston area. Our phased approach minimizes tenant disruption while replacing deteriorating plumbing with modern, long-lasting materials.

What Is Multi-Family Repiping?

Multi-family repiping is the complete replacement of water supply lines throughout a building or complex that serves multiple residential units. Unlike single-family homes, a multi-family repipe in Houston requires careful coordination between property management, tenants, and our crews to ensure water service interruptions are brief and planned.

We repipe all types of multi-family properties:

• Apartments — garden-style complexes, mid-rise buildings, and large communities
• Condominiums — individual unit repiping coordinated with HOA boards
• Townhomes — attached and semi-attached communities with shared walls
• Duplexes and fourplexes — smaller multi-unit properties
• Mixed-use buildings — commercial ground floor with residential above
• Strip centers — retail spaces with plumbing infrastructure requiring replacement

Whether your property has 4 units or 400, we design a repiping plan that fits your building’s layout, your budget, and your tenants’ schedules.

Why Multi-Family Buildings Need Repiping

Multi-family properties face accelerated pipe deterioration compared to single-family homes. Higher water demand, more fixtures, and decades of continuous use take a toll on aging plumbing systems. Here are the most common reasons Houston property owners choose to repipe:

Aging Infrastructure

Most Houston apartment complexes built between the 1960s and 1980s were plumbed with galvanized steel pipes. After 40 to 60 years, these pipes corrode from the inside out, restricting water flow and contaminating water with rust. If your building was constructed before 1990, your pipes are likely past their intended lifespan.

Tenant Complaints

Low water pressure, discolored water, inconsistent hot water, and frequent leaks are the top tenant complaints that signal pipe failure. These issues drive turnover — replacing a tenant costs far more than fixing the root cause.

Liability and Property Damage

A single pipe burst in a multi-story building can damage multiple units simultaneously. Water damage claims, mold remediation, and displaced tenants create significant financial exposure. Proactive repiping eliminates this risk.

Insurance Concerns

Many insurance carriers in Texas are increasing premiums — or declining to renew coverage — for properties with aging galvanized or polybutylene plumbing. A full repipe can reduce your insurance costs and ensure continued coverage.

Common Pipe Materials in Houston Multi-Family Buildings

Houston’s multi-family housing stock contains several pipe materials, each with known failure patterns:

• Galvanized steel — Found in buildings from the 1950s through 1980s. Corrodes internally, causing rust-colored water, pinhole leaks, and severely reduced water pressure. This is the most common material we replace in Houston apartments. Learn more about galvanized pipe problems.
• Copper — Used from the 1960s onward. Generally durable but susceptible to pinhole leaks from Houston’s aggressive water chemistry, especially in recirculating hot water systems common in multi-family buildings.
• CPVC (chlorinated polyvinyl chloride) — Common in 1990s and 2000s construction. Becomes brittle over time, especially in hot water lines and areas exposed to sunlight or heat in attic spaces.
• Polybutylene (Poly-B) — Installed from the late 1970s through mid-1990s. Subject to a major class-action lawsuit due to premature failure. If your property still has polybutylene, replacement should be a top priority.

We typically replace these materials with PEX (cross-linked polyethylene) or copper, depending on the property’s requirements, local codes, and your budget. PEX is the preferred choice for most multi-family repiping projects due to its flexibility, corrosion resistance, and faster installation time.

Our Multi-Family Repiping Process

Repiping an occupied multi-family building demands a structured, phased approach. Here is how we handle every multi-family repipe Houston project from start to finish:

1. Building Assessment

We conduct a thorough evaluation of your property’s plumbing system, including pipe material identification, water pressure testing, visual inspection of accessible pipes, and review of maintenance records. We provide a detailed written assessment with photos and a recommended scope of work — at no cost.

2. Custom Repiping Plan

Every multi-family building is different. We create a unit-by-unit plan that accounts for pipe routing, wall and ceiling access points, fixture locations, and common area plumbing. For larger properties, we develop a phased schedule that keeps the majority of units online at all times.

3. Tenant Communication

We provide advance notice templates and schedules for your property management team to distribute. Tenants receive clear information about what to expect, how long their water will be off, and what areas of their unit will be accessed.

4. Phased Repiping — Unit by Unit

We work through the building systematically. Our crews complete each unit before moving to the next, so tenants experience a single day of disruption rather than weeks of ongoing construction. Water shutoffs are limited to the unit or section being worked on.

5. Drywall Repair and Restoration

Repiping requires opening walls and ceilings to access pipes. We handle all drywall patching, texturing, and preparation for paint as part of the project. Your units are left ready for a fresh coat of paint — or we can paint to match if needed. See our complete repipe process.

6. Inspection and Testing

Every completed section is pressure tested and inspected before we close walls. We coordinate City of Houston plumbing inspections and provide all documentation for your records.

7. Final Walkthrough

We walk each completed unit with your property manager to confirm all fixtures are operational, water pressure is restored, and the workspace is clean.

Timeline Expectations

The timeline for a multi-family repipe depends on the number of units, building layout, and pipe accessibility:

• Standard pace: 1 unit per day per crew
• Accelerated pace: 2 to 3 units per day with multiple crews running simultaneously
• Duplex or fourplex: 2 to 4 days total
• Small apartment complex (8-20 units): 2 to 4 weeks
• Large apartment community (50+ units): Phased over several months, with sections completed and returned to service throughout

We work around your property’s needs. If you have seasonal vacancy patterns or prefer weekday-only work, we accommodate your schedule. Weekend and extended-hour work is available for properties that need faster completion.

Cost Factors for Multi-Family Repiping

For single-family cost ranges, see our Houston repipe pricing page.

Every multi-family repiping project is priced based on the unique characteristics of your property. The primary cost factors include:

• Number of units — More units means a larger project, but per-unit costs typically decrease with volume
• Number of stories — Multi-story buildings require more vertical pipe runs and may need additional access points
• Pipe accessibility — Slab-on-grade buildings with pipes in walls are more straightforward than buildings with under-slab plumbing or pipes in hard-to-reach chases
• Material choice — PEX is generally more cost-effective than copper; we help you choose the right material for your building’s needs
• Fixture count per unit — Units with multiple bathrooms, kitchens, and laundry connections require more piping
• Common area plumbing — Laundry rooms, pool houses, community kitchens, and irrigation connections add scope
• Drywall and finish scope — Standard patch-and-texture is included; full paint matching or specialty finishes may add cost

Repipe vs. Spot Repair: A Comparison for Property Managers

Factor	Full Repipe	Spot Repairs
5-Year Total Cost	One-time investment; no further pipe-related costs	Recurring emergency calls add up; often exceeds repipe cost within 3-5 years
Tenant Disruption	Planned, one-day disruption per unit	Unpredictable emergency shutoffs affecting multiple units
Warranty	Comprehensive warranty on all new piping and workmanship	Limited warranty on individual patch repairs only
Property Value	Significant increase; strong selling point for buyers or refinance	No meaningful impact on property value
Insurance Impact	Lower premiums; easier renewals with new piping	Premiums continue rising; risk of non-renewal
Water Quality	Clean, clear water throughout the building immediately	Remaining old pipes continue to corrode and contaminate water
Long-Term Reliability	New system rated for 25-50+ years	Next failure is always imminent in aging systems

For most multi-family properties with pipes over 30 years old, a full repipe is the more cost-effective solution when measured over a 5-year horizon — and the only solution that truly eliminates ongoing plumbing risk.

Property Manager Checklist: Signs Your Building Needs Repiping

Use this checklist to evaluate whether your multi-family property is a candidate for repiping. If you check three or more items, it is time to schedule a building assessment:

• ☐ Building was constructed before 1990
• ☐ Pipes are galvanized steel, polybutylene, or aging CPVC
• ☐ Tenants report brown, yellow, or rust-colored water
• ☐ Multiple units experience low water pressure
• ☐ You are fielding more than 2 plumbing repair calls per month
• ☐ You have had a pipe burst or major leak in the past 12 months
• ☐ Insurance company has flagged plumbing concerns or raised premiums
• ☐ Water damage repairs are becoming a recurring budget item
• ☐ You are planning a property sale, refinance, or major renovation
• ☐ Tenants are not renewing leases due to water quality or pressure complaints

Benefits for Property Owners and Managers

Reduced Maintenance Costs

Emergency plumbing calls, water damage remediation, and ongoing patch repairs drain your maintenance budget. A full repipe eliminates these costs and frees your maintenance team to focus on other priorities.

Increased Property Value

New plumbing is a capital improvement that directly increases your property’s appraised value. For properties preparing for sale or refinance, a completed repipe is a strong differentiator that buyers and lenders recognize.

Lower Insurance Premiums

Texas property insurers reward updated plumbing. Many of our multi-family clients see meaningful premium reductions after providing documentation of a completed repipe.

Tenant Retention

Clean water, strong water pressure, and zero disruptions from emergency repairs keep tenants satisfied and renewing leases. In Houston’s competitive rental market, reliable plumbing is a retention tool.

Frequently Asked Questions for Property Managers

Do tenants need to vacate during repiping?

No. Tenants can remain in their units. Water is typically shut off for 4 to 6 hours while we work in that specific unit. We coordinate timing with your property management team so tenants can plan around the shutoff. Units are fully functional by the end of each work day.

How do you handle common area plumbing?

Common area plumbing — including laundry rooms, pool facilities, clubhouses, and main supply lines — is addressed as part of the overall repiping plan. We schedule common area work during low-usage hours to minimize impact on tenants and building operations.

What about permits and inspections?

We pull all required City of Houston plumbing permits and coordinate inspections as part of every project. All permits and inspection records are provided to you for your property files. Our team handles the entire permitting process — you do not need to manage any of it.

Can you work weekends or after hours?

Yes. We offer flexible scheduling including weekends and extended hours for properties that need to minimize weekday disruption or accelerate project timelines. We work with your property management team to find the schedule that works best for your tenants.

Do you handle drywall repair?

Yes. All drywall patching and texturing is included in our repiping scope. We cut access points as small as possible, then repair, texture-match, and prepare surfaces for paint. We can also provide painting services to restore units to move-in condition.

What warranty do you provide?

We provide a comprehensive warranty covering both materials and workmanship on all multi-family repiping projects. PEX piping carries a manufacturer warranty of 25 years, and our labor warranty ensures you are covered if any issues arise with our installation. Full warranty details are provided in your project proposal.
