Short definition
Second fix (UK term; “trim-out” or “finish” in US) is the construction phase where the visible plumbing fixtures — toilets, faucets, sinks, tubs, showerheads, hose bibs, water heaters — are installed onto the rough-in stub-outs after drywall, paint, and finish flooring are complete. It’s the last plumbing labor before the final inspection.
What it is
Standard sequence: rough-in → rough-in inspection → drywall + paint + tile + flooring → second-fix → final inspection. Second-fix typically ends with a punch list (UK: “snagging”) of small items needing touch-up.
For a 2026 Seattle bathroom remodel: rough-in $2,500–$8,000; second-fix $1,500–$5,000; total plumbing $4,000–$13,000. Second-fix labor runs 20 to 35% of total plumbing budget; material costs (fixtures, valves, supply lines) are 40 to 60%.
Why it matters to a homeowner
Two homeowner-protection rules at the second-fix stage:
- Never pay the final installment before the final inspection passes AND the punch list is complete. A common scam pattern is to push for final payment on the day of second-fix completion, before the inspector has visited. The inspector finds issues, the contractor disappears, and you’re paying twice — once to the original contractor, once to the next one to fix the problems.
- Verify lien releases at every progress payment. Under WA RCW 60.04, subcontractors retain mechanic’s lien rights even after you’ve paid the prime contractor. If your prime hasn’t paid the subs, the subs can lien your property — and your “I already paid the contractor” defense doesn’t apply. Lien-release docs at each milestone protect you.
If a contractor says “we’re doing the second fix tomorrow, then we’re done” — verify the inspector is scheduled for the day after, not weeks out. Don’t write the final check on the day of work completion.
When you’ll encounter this term
- A contractor’s quote with separate phases for rough-in and second-fix.
- A UK-source forum thread (cg1, cg2 references).
- A snagging or punch-list document at the end of a job.
- A WA L&I inspector verifying water-heater earthquake straps at final.
Common variants and not the same as
- Second fix (UK) vs. trim-out (US). Same phase, different name.
- Second fix vs. final inspection. Second fix is the work; final inspection is the regulatory verification.
- Second fix vs. commissioning. Commissioning (balance, flush, fill, function-test) applies more to hydronic and HVAC. Different scope from potable-water trim-out.
Common failure modes
- No backer in walls for grab bars or wall-hung sinks. The blocking should have been added at rough-in. Wall-hung items pull out of drywall.
- Trim brand changed between rough-in and second-fix. Incompatible with the rough-in valve. Order trim before rough-in for hard-to-source items.
- Second-fix on uncured drywall. Wait per drywall manufacturer (typically 24 hours after final coat).
- Final payment before inspection. Major scam pattern. Don’t do it.
Washington note
WA L&I water-heater earthquake straps (two-strap installation, top and bottom thirds of the tank) are verified at final inspection. This is one of the most common second-fix oversights that fails inspection. Inspectors also verify pressure-test sign-off, gas-leak test, faucet function, and drain function at final.
WA RCW 60.04 mechanic’s lien framework: lien-release docs at each milestone are the homeowner’s main protection. Without them, a sub who didn’t get paid by your prime can lien your home — and your payment to the prime is not a defense.
