Two Siding Quotes Nine Thousand Dollars Apart Are Not The Same Job
Three quotes came back. Three quotes for siding installation pittsburgh pa, all written for the same 1,150 square foot brick and frame rowhouse east of the city. Three quotes, and the cheapest read $11,400 while the highest read $20,300. Nobody at that kitchen table could explain the gap. The myth is that the spread is markup, that the expensive contractor charges more for identical work and the thrifty buyer simply refuses to pay it. Reality is duller and more useful, because the cheaper bid is almost always the shorter job, and the difference lives in the parts of the wall nobody photographs.
The Same Word Covers Very Different Panels
Vinyl is not one product. A builder grade panel runs around .040 inches thick with a hollow back, and on a spec sheet it prints the same five letters as a .046 inch insulated panel that costs roughly double and lies flatter against an old wall. Fiber cement is heavier again, slower to cut, and it needs more hands on the ladder, so the labor line moves before the material line does. The $11,400 proposal on that rowhouse was priced around thin hollow vinyl with the existing trim left alone, while the $20,300 proposal was insulated fiber cement with new trim, new corners and new soffit. Same word on both.
Wall Prep Hides In The Fine Print
Under the panel is where the money actually goes. Walking that rowhouse turned up soft sheathing beneath a second floor window, two courses of failed flashing, a bowed stretch of wall that needed furring out, which is what crews call nailing thin strips across the studs to true up a wavy surface before anything gets hung, and a downspout emptying straight against the foundation. None of that appeared on the cheap proposal, because the estimator never walked past the driveway. Job after job, the wall that looks fine from the sidewalk is the one that adds two days and a lumber run. An estimator who circles the whole house, opens a corner, and writes down what he found is quoting a different project than the one pricing it off satellite imagery, and those two numbers were never going to agree.
How much siding failure in a neighborhood like that traces back to bad prep rather than a bad panel, I honestly cannot tell you. Nobody tracks tear-offs that way, and the crew pulling the old wall down has no reason to publish what was hiding behind it. What is visible from the callbacks is that the trouble clusters at windows, corners and roof intersections, not out in the middle of the panel face.
Per Square Foot Pricing Rarely Matches Real Work
Every proposal quotes by the square, which makes three of them look comparable when they usually are not. Wall area is not floor area, and a rowhouse carrying a gable end, a dormer and three window returns generates far more cut waste than a flat box of the same footprint. Search siding installation Pittsburgh PA and you will find companies willing to hand you a tidy per foot number over the phone, sight unseen. That figure is a guess dressed as a price, and the guess gets corrected later, usually as a change order signed after the old siding is already in the dumpster.
Warranty Language Says More Than Brand Names
Every bid names a manufacturer warranty, and every manufacturer warranty covers the panel rather than the person who hung it. The line worth reading is the labor coverage: one year, two years, five, or the phrase workmanship guaranteed with no term attached to it at all. A contractor who commits two years to his own labor has priced in the cost of driving back out, and that cost is part of why his number sits higher than the one underneath it. Ask what a claim actually looks like, who pays to pull panels off the wall, and whether the coverage survives a sale, since a starter house is a house somebody tends to sell inside six years.
The Cheaper Bid Is Usually The Shorter Scope
None of this makes the low bid dishonest. Labor by itself swings enormously, and a January 2026 cost breakdown from Hover puts siding installation labor at $2 to $12 per square foot, so a 1,000 square foot job can carry anywhere from $2,000 to $12,000 in labor before one panel is paid for. Two honest contractors can sit at opposite ends of that range and both be quoting fairly, because they are quoting different crews and a different number of days on the wall.
So make them price the same job. Hand every bidder one written scope covering the panel line and thickness, what happens if the sheathing is rotted, flashing at every opening, trim and soffit, and the labor warranty term in years. Once three contractors are pricing identical scope, the spread usually collapses to a couple of thousand dollars, and the cheap outlier stops looking like a bargain. The owner of that rowhouse rebid it exactly that way and landed at $14,900, which was nobody’s original number and a great deal closer to the real one.
