Map Every Branch, Fixture and Repipe Responsibility
A whole-home estimate should explain how completeness will be established. Count fixtures and branches, trace known routes and document what remains concealed before access is priced.
1
Create a floor-by-floor fixture inventory
List every sink, toilet, tub, shower, appliance connection, hose bib, water heater and other supplied fixture by floor and room. Add visible shutoffs, manifolds and branches, then mark areas where piping disappears behind finishes. A count alone is not enough: identify which fixtures are included in the proposed repipe and which are excluded or awaiting confirmation. Note suites, additions and renovated rooms because they can have different routing or materials. Give the same inventory to each estimator so pricing differences reflect proposed work rather than different assumptions about the building.

2
Trace known routes and record concealed limits
Draw a simple line from the service entry or main shutoff through visible distribution areas toward each fixture group. The drawing does not need to predict concealed routing; it needs to show what is known and where the evidence ends. Mark finished ceilings, tiled walls, cabinets, chases and other access constraints. Ask each estimator how the proposed replacement route addresses those limits and where exploratory access may be needed. This prevents a broad whole-home label from hiding an allowance that covers only the easiest visible branches.

3
Define the replacement boundary
Write the start and end points of the work: service entry, meter area, main shutoff, distribution branches, fixture shutoffs and connections. Clarify whether specialty fixtures, irrigation, fire-protection components, exterior lines, suites or shared building systems are outside the intended scope. Replacement material, sizing and connection details require qualified design and property-specific review, so ask for current product information and a written description rather than selecting from a generic checklist. The scope should also say how abandoned piping will be treated and identified in the closeout record.

Pair every route with an access plan
For each proposed branch, identify the likely wall, ceiling, cabinet or chase access and the rooms affected. State who will move contents, protect floors, control dust, secure openings and coordinate occupants. If the route depends on an exploratory opening, label it as a preconstruction decision rather than a fixed assumption. Tile, cabinetry and rated assemblies need specific treatment and may change the routing decision. A complete repipe estimate should make access visible enough that two proposals can be compared room by room instead of relying on the phrase access as required.

5
Assign drywall and finish restoration
List every expected patch and identify the intended finish level, texture, primer, paint area, trim, cabinet reassembly and colour-match limitation. Some proposals include only rough closure while others include painting; those are not equivalent scopes. Note whether restoration is performed by the plumbing contractor, a separate trade or the owner. Include a written change process for additional openings discovered after work starts. Keeping restoration beside each plumbing route reduces disputes and helps the property owner understand the full project cost rather than comparing pipe installation alone. Confirm whether the offer is plumbing-only or includes coordinated finish restoration, which party signs each trade contract, and who resolves an access change between those contracts.

6
Specify testing, inspection and closeout
Ask the qualified contractor to describe appropriate pressure or operational testing, fixture checks, insulation replacement and any required municipal inspection sequence. Coquitlam, Port Coquitlam and Port Moody maintain separate processes, so the property address and proposed work determine which authority must be contacted. Before walls are closed, plan photographs of completed routes and connections where permitted. The final file should include applicable permits and inspection records, product information, warranty terms, labelled shutoffs, approved changes and a clear list of any piping left outside the project.

Compare completeness before comparing totals
Place estimates beside the same fixture inventory and route map. Confirm that each one addresses the replacement boundary, access assumptions, protection, restoration, testing, permits and closeout. If a line is absent, ask whether it is included, excluded or unresolved instead of assuming the lowest total covers it. Use the access, strata, permit-record and quote-comparison pages to resolve property-specific responsibilities. A strong final scope should let an owner, strata council or reviewer follow each branch from current evidence through proposed replacement, restored finish and retained record.
