Where bids go wrong
What other plumbing estimates miss.
Fixture carriers, trim and stops, which are counted per fixture and often left in the allowance.
Pipe by size and material separately — the same run in copper and PEX are different bids.
Hangers, sleeves, firestopping and insulation on every run through a rated assembly.
Excavation, bedding and backfill for underslab work, which belongs to this trade on most jobs.

FAQ
Plumbing Estimating, answered.
Talk to an estimator
Not a salesperson. Same-day answers on working days.
+1 518 974 7222[email protected]Do you count fixtures and measure pipe?
Yes. Fixtures are counted from the schedule, and pipe is measured by size and material for each system.
Is underground plumbing included?
Yes. Under-slab sanitary and water are measured separately from above-ground work.
Can you use our cost book and labor rates?
Yes, and we prefer it. Your historical costs reflect your crews and your suppliers better than any published average. Send the template and we work inside it.
How does pricing work?
Pricing is per project and quoted before any work starts — no retainer, no minimum volume and no subscription.
Do you sign NDAs?
Yes. Drawings, specifications and pricing are treated as confidential by default, and we sign your NDA on request before any documents change hands.
