Plumbing bid fairness checker.

Water heater pricing is where homeowners get taken most often, because nobody shops it until the basement is cold. A fair water heater installation runs $1,734 to $2,003 nationally in 2026; the work itself costs about $1,510 to deliver. Drop the bid in below. The checker reads every line, checks the permit math, and tells you if the number is padded.

Fair range. Cost to deliver is the break-even, the red line on the gauge, not the price to demand. A fair bid sits in the green band above it: most jobs land at a 15 to 22 percent margin on the bid, roughly 18 to 28 percent over the cost to deliver, leaner or richer by trade and market. Contractors earn that, and they should: nobody works for free, and if the job were easy you would not need one.

Built, not guessed.

The checker rebuilds the job from primary data: Craftsman hours at your metro's loaded BLS wage, FRED PPI materials, the verified permit fee, and NAHB overhead. That sum is the cost to deliver. A fair bid sits 8 to 14 percent over it at the lean floor and 24 to 45 percent at the premium ceiling, scaled by your trade and metro. Read the full methodology.

Bid checker questions.

What is a fair price for water heater installation?
In 2026, a fair water heater installation bid runs $1,734 to $2,003 nationally. The cost to deliver sits at $1,510, and an honest margin lands roughly 15 to 33 percent above it depending on the metro.
What does the checker compare my bid against?
Every benchmark is built, not scraped: Craftsman labor hours times BLS metro wages with burden, FRED PPI-adjusted materials, verified city permit fees, and NAHB overhead. The verdict places your number on a ladder from below cost to premium against the fair band for your metro.
Is a bid far below the cost to deliver a good deal?
Usually the opposite. A bid below the cost to deliver means someone is cutting scope, insurance, or quality to get there, and the checker flags it as below cost rather than calling it a bargain.
Why should the contractor make a profit on top of the cost to deliver?
Because nobody works for free. Cost to deliver is the break-even: labor, materials, permits, and overhead with zero profit in it. The 18 to 28 percent most contractors keep over that, a 15 to 22 percent margin on the bid, pays for the license, the insurance, the warranty callback, and the judgment you are actually hiring. If the job were easy, you would not need a contractor at all. Use the floor to spot padding, not to demand free work.
Should the permit be on my water heater bid?
In most metros, yes, and it is one of the most padded lines we see. The checker compares the permit line against your city's published fee, so a $400 charge against a $150 fee gets called out instead of riding through.
