Aging rental stock and HOA-managed buildings tend to develop the same galvanized or copper pinhole leaks that single-family homes do, just at a bigger scale, with more units and more tenants affected each time one shows up. If you’re managing that risk unit by unit as leaks happen, a planned, phased repipe is usually a more predictable path than repeat emergency calls, and we schedule that work phased, unit by unit or building by building, so occupied units keep running water outside their own service window.
A multi-unit repipe doesn't have to mean emptying the building. We schedule the work phased, unit by unit or building by building, so occupied units keep running water outside their own service window and tenants get advance notice before we're on-site.
We coordinate directly with you on the sequence: which units or buildings go first, how much advance notice tenants need, and which access points require your team's help getting residents informed. How water supply is handled across the building — which units are affected, when, and for how long — is agreed with you in writing before work starts, so notices can go out with real dates on them rather than estimates.
A multi-unit repipe scope typically distinguishes between unit-level supply lines and any shared common-area plumbing, main risers, shared mechanical rooms, or building-wide shutoffs, that serve more than one unit. We walk the property with you before quoting, so the scope reflects what your specific building actually needs rather than a generic per-door estimate.
Depending on your building's layout, the project may involve repiping individual units on a rotating schedule, addressing common-area risers as a separate phase, or both, coordinated so that a unit isn't opened up twice for work that could have been sequenced together. We'll lay out the specific phasing plan for your property as part of your written quote, not as a one-size answer that ignores your building's actual configuration.
The question on a multi-unit property is rarely whether a repipe is needed, but how much of it, and that decision should rest on evidence rather than on the age of the building.
What is failing, and how. Galvanized steel corrodes internally until water pressure at the fixtures drops noticeably, and residents usually report that before they report a leak. Copper fails differently, through galvanic corrosion producing isolated pinholes. Which of the two you have changes whether a building-wide replacement or a targeted spot repair on the affected stack is the right spend.
Establishing it without disruption. We confirm what is in the walls non-invasively wherever we can, so scoping does not mean opening finished units. If the diagnostic visit cannot establish it, the no-find-no-fee guarantee applies to that visit, and the visit itself is a flat-rate fee agreed in advance so a board can approve a known number.
What the replacement can change. A repipe is also the moment to reconsider layout. A manifold configuration gives each unit or fixture group its own run from a central distribution point, so a future shut-off affects one unit rather than a whole riser, which matters more in occupied multi-family buildings than it does in a single house.
Permits. Repiping is permitted, inspected work. We pull the permit, and the signed-off inspection becomes part of the documentation set described below.
Every repipe project comes with a written scope and documentation you can put in front of your board or keep in your property files, including before-and-after photos and the workmanship warranty details. This documentation supports your own recordkeeping; it isn't a statement about your insurance coverage or liability, which depends on your own policy and carrier.
That written scope spells out exactly what was repiped, by unit or building section, along with photo documentation and the 2-year workmanship warranty terms that apply to the work. It's the same kind of paperwork Kevin Nguyen, our Field Inspector, produces on every job we complete, useful for a board vote record, a capital-improvement file, or a future buyer's due diligence on the property, none of which requires us to make any claim about your insurance or liability position. That determination stays with your policy and your carrier, not with us.
Repipe pricing for a multi-unit project is scoped per project in a firm written quote, following the same per-unit range that applies to a single-family whole-house repipe, typically $6,000 to $15,000 per unit, adjusted for your building's specific access, common-area scope, and material choice.
A repipe of this size is also a real capital expense for a board or ownership group, and we don't have a financing program to point you to today; if payment timing or phasing the cost across a budget cycle matters for your organization, raise that during your walkthrough as well, before you commit to anything.
See our full whole-house repipe cost breakdown for what drives the per-unit number, and our PEX vs. copper comparison if your board is weighing which material to standardize on across the property.
Every unit or building section we repipe carries our 2-year workmanship warranty, the same guarantee that applies to a single-family repipe. If PEX is the material your board selects, manufacturers typically offer their own separate material warranty, and we'll confirm those exact terms once materials are selected for your project, rather than quote a blanket figure across every unit before we know the specifics.

Contact us to start that conversation and schedule a walkthrough, Monday through Saturday, 7am to 6pm. We also keep a 24/7 emergency line for a genuine plumbing emergency at one of your properties.
We walk the property with you first, then phase the work unit by unit so occupied units keep running water outside their own window.

Yes. Every project includes a written scope and photo documentation you can put in front of your board or keep in your property files. This documentation supports your recordkeeping; it isn’t an insurance or liability statement on your behalf.
Phased scheduling, advance tenant notice, and coordinated access-point planning with your property team. The water-supply schedule across the building is agreed in writing before work starts, so your notices carry real dates. The project still remains genuinely disruptive to specific units on specific days.
Pricing is scoped per project in a firm written quote. No standing volume or portfolio discount is currently published; raise your specific situation during the walkthrough and we’ll talk through it directly.
A whole-house repipe typically runs $6,000 to $15,000 per unit, the same range that applies to a single-family home, adjusted for your building’s access and common-area scope. See our full repipe cost breakdown.
We stop, document what we found, and bring it to you before doing any additional work or adding it to the original quote. We don’t fold a surprise into the project scope without telling you first.
