Plumbing
Service calls (leak detection, water-heater swaps, fixture replacements), water-heater changes (tank, tankless, hybrid heat-pump), sewer-line replacements, gas-line work, remodel rough-ins, and backflow preventer testing. Sealed bidding forces every C-19 plumbing contractor in your ZIP to bid the same scope at the same time, so the envelope you open is the cheapest compliant path — not the only number the dispatcher quoted you.

Scope
What fits this trade on Bidmark.
Service calls (leak detection, water-heater swaps, fixture replacements), water-heater changes (tank, tankless, hybrid heat-pump), sewer-line replacements, gas-line work, remodel rough-ins, and backflow preventer testing. Sealed bidding forces every C-19 plumbing contractor in your ZIP to bid the same scope at the same time, so the envelope you open is the cheapest compliant path — not the only number the dispatcher quoted you. Posting a scope that fits the sealed-envelope model — work that can be photographed, line-itemed, and bid head-to-head against other licensed contractors in your state — is the fastest path to a competitive bid ledger.
- Credential gate: every bidder clears a one-time license check and carries active general liability at the moment your window closes.
- Fee tier: the same tiered fee schedule applies to plumbing as to every other trade — your envelope cost scales to your scope.
- Sealed window: every bidder parties to the same scope and the same close time, so the envelope you open is a real head-to-head price, not a last-minute undercut.
