The “low bid” on a Kansas City multifamily siding project is usually low because of what it left out — tear-off, rot repair, the water-resistive barrier, or kick-out flashing. A bid and scope review fixes that by turning the project into one written scope every vendor prices the same way. When three bids come back priced against the same tear-off, rot allowance, WRB, flashing, trim, disposal, access, and warranty, the dollar differences finally mean something. This page shows a KC board, manager, or apartment owner what a complete bid must include, how to spot the gaps, and how the review works.
Why three siding bids never actually match
Vendors scope differently — sometimes by mistake, sometimes on purpose. One includes full tear-off; another sides over the old, failing cladding and never sees the wall’s real condition. One carries a defined rot-repair allowance; another writes “rot repair extra” and back-charges it at full price later. One prices kick-out flashing; another leaves it off. The dollar figures look comparable, but they’re pricing different projects — so the cheapest number usually belongs to the least-complete scope, and the gap surfaces as change orders mid-job.
The omissions that most often make a low bid look low:
- Tear-off — re-cladding over old, failing siding hides the wall’s condition.
- The rot/sheathing repair allowance — left out, it becomes an uncontrolled change order.
- Flashing — especially kick-out flashing where roofs meet walls.
- The water-resistive barrier — the layer that actually prevents the next leak.
- Disposal, access, and resident notices — real costs that quietly vanish from thin bids.
What a complete multifamily siding bid includes
Every bid should spell out the same line items, each priced separately, so a board can see what’s in and what’s missing. A bid with all of these is comparable; a bid missing several is a future negotiation.
| Line item | Why it matters |
|---|---|
| Material and profile (HZ5 if Hardie) | The wrong spec is the wrong climate match |
| Full tear-off | Re-cladding over failure hides it |
| Rot / sheathing repair allowance | KC hardboard and stucco hide rot |
| Water-resistive barrier (WRB) | The drainage plane that prevents leaks |
| Flashing, including kick-out | The most common hidden-leak source in KC |
| Trim and accessories | Often dropped to lower a bid |
| Disposal and site protection | Tear-off volume is real cost |
| Access equipment | Lifts and scaffold on tall elevations |
| Resident-disruption plan | Occupied-building requirement |
| Permit and inspection responsibility | Required for KC MO multifamily; licensed contractor on the Kansas side |
| Warranty terms — material and labor | Defines who fixes a future failure |
| Separated alternates for phasing | Lets the board spread cost |
Hold every bid against this list. The most dangerous omissions are the invisible ones — rot repair and flashing — because they’re hidden until the wall is open. Full detail: what a real multifamily siding bid must include.
The four areas that decide the outcome
A scope review organizes the project around the four things that actually drive cost and risk on a KC multifamily building, so nothing important gets priced by accident. Each one maps to a section of the bid document.
| Area | What it covers | Why it decides the outcome |
|---|---|---|
| 1. Hail resistance and the wall | Impact-rated cladding, WRB, flashing, kick-outs, sheathing repair | In KC, the wall and the hail rating decide whether you’re back in a claim |
| 2. Resident disruption and access | Parking, balconies, entrances, noise, notices, sequencing | Occupied buildings make logistics the board’s problem |
| 3. A comparable bid scope | Line-item quotes, defined allowances, separated alternates | A scope every vendor prices the same is what a board can defend |
| 4. Funding and assessment reality | Reserves, special assessment, loan, MO/KS rules | Neither MO nor KS requires reserves, so the bill often beats the savings |
How the rot allowance and alternates keep a project honest
Two tools keep a phased KC project from blowing up: a rot allowance and separated alternates.
A rot/sheathing allowance puts a defined dollar figure on hidden damage so it’s budgeted, not back-charged. KC’s 1980s–90s hardboard and stucco routinely hide rot behind the cladding, and you can’t know how much until the old siding comes off. A bid with no allowance — or a token one — looks cheaper but transfers all that risk to the association as full-price change orders. The fix is to require a stated allowance with a defined unit rate, so every bidder prices the same assumed rot quantity and overages bill at a pre-agreed rate. That converts an unknown into a controlled variable instead of a blank check.
Separated alternates do the same for phasing. They price optional or later scope — a second building, a trim upgrade — apart from the base bid, and lock unit prices so building 12 costs what building 1 did. Together, allowances and alternates prevent the two classic blowups: surprise change orders and drifting phase pricing. (Any real dollar figures need live KC quotes — flagged below.)
How the scope review works
It’s a four-step process that runs before bids go out, then again when they come back:
- Define the scope. Walk the four areas across your building — hail and wall, residents, the bid line items, the funding.
- Write the bid document. Turn it into a like-for-like scope every vendor prices the same way, with alternates separated.
- Review the returned bids. Compare line by line, flag the omissions, and translate the differences into plain language for the board or owner.
- Map the funding. Tie the chosen scope to reserves, a special assessment, or a loan under Missouri or Kansas rules, so the decision is fundable as well as defensible.
Who reviews this
Built with input from a Kansas City exterior crew that does occupied-building multifamily siding work, led by a contractor who spent more than 15 years at the James Hardie National Office training installers on correct installation and warranty compliance — the wall details a bid either prices honestly or quietly skips. We don’t present that crew’s reviews or ratings as this site’s own.
FAQ
Q: What should a multifamily siding bid include? Material and profile, full tear-off, a defined sheathing/rot allowance, the water-resistive barrier, flashing (including kick-out), trim, disposal, access equipment, a resident-disruption plan, permit and inspection responsibility, warranty terms for both material and labor, and separated alternates for phasing. A bid missing these isn’t cheaper — it’s less complete, and the omissions return as change orders.
Q: How do I compare siding bids that look nothing alike? Put them on a single written scope. When every vendor prices the same project, the dollar differences become meaningful instead of misleading. The most common gaps — tear-off, the rot allowance, kick-out flashing, the WRB — are exactly where a low bid cuts.
Q: Why does a low bid often cost more in the end? Because the low number usually reflects a thinner scope: siding over old cladding, no rot allowance, omitted flashing. Those items don’t vanish — they reappear as change orders once the work is underway, often pushing the “cheap” bid past the complete one.
Q: Do we need a permit and a licensed contractor? For multifamily in Kansas City, MO, yes — a permit is required (only 1–2 family is exempt). On the Kansas side, Johnson County requires a licensed contractor for permitted work, and commercial projects can’t be owner-performed (Johnson County Contractor Licensing). The scope should assign permit and licensing responsibility explicitly.
Q: What’s the single most-skipped line item? The rot-repair allowance and the flashing detail, because both are hidden until the wall is open. Requiring a stated rot allowance and itemized flashing is the most protective thing a board can do before signing.
Q: Is this site a licensed contractor? No. This is a Kansas City multifamily siding planning resource that helps boards, managers, and owners define scope and review bids before signing, then connects them with a local crew that performs the work.
