How to Estimate a Kitchen Remodel: A Builder's Cost Breakdown

Sound Familiar?

Signs your kitchen remodel estimates are off:

• You've had kitchen jobs that looked profitable at the bid stage finish in the red
• You're regularly issuing change orders mid-project for conditions you should have anticipated
• Your cabinet and countertop costs are frequently different from what you bid
• You're not pricing client-supplied materials risk into your labor rates
• You bid the work without a site visit and scope walk with the homeowner

What We Found

The Five Cost Categories in a Kitchen Remodel Estimate

A complete kitchen remodel estimate has five distinct cost buckets. Missing or underpricing any one of them creates margin bleed.

1. Demolition and Site Prep

Dumpster or haul-away, demo labor, cabinet removal, countertop removal, flooring removal (if included in scope), wall opening if layout changes. For a typical 150–250 sq ft kitchen, expect $2,500–$6,000 in demo costs depending on scope and disposal fees in your market. The mistake here: assuming demo is clean. Plan for one wall opened before you discover aluminum wiring, asbestos tile underneath the current floor, or plumbing that isn't where the drawings say it is.

Standard practice: add a $1,500–$2,500 hidden conditions allowance in every kitchen estimate unless you've done invasive inspection. Not as a line item you'll hide — as a transparent allowance that converts to a change order credit if not used. Clients who've done remodels before will understand it. Clients who haven't need to be educated on it before the contract is signed.

2. Cabinets and Installation

The widest variance line in any kitchen bid. Stock cabinets from a box store run $3,000–$8,000 for a typical kitchen. Semi-custom cabinets from a dealer run $8,000–$20,000. Full custom run $20,000–$60,000+. These are installed costs — cabinet cost plus delivery plus installation labor.

Three things to nail down before you bid cabinets: (1) who is supplying them (GC or homeowner?), (2) lead time (custom cabinets are 8–14 weeks — your schedule needs to account for this), and (3) who is responsible for damage if the wrong item ships or dimensions are off. Client-supplied cabinets are a liability transfer you need to price into your installation rate — if the wrong size shows up on delivery day, your installation crew is waiting, your schedule slips, and you're not getting paid for it.

3. Countertops

Laminate runs $1,500–$3,500 installed. Quartz or granite runs $3,500–$12,000+ depending on slab choice, edge profile, and linear footage. Marble runs higher. Confirm the material selection before finalizing the bid — "granite countertops" is not a specification. Get the supplier, the slab, and a templating date on the calendar before you commit to a countertop price. Countertop subs need a template after cabinets are installed, and their lead time after templating is typically 7–14 days. That's a scheduling constraint you need to build into the project timeline.

4. Appliances and Fixtures

This is frequently a client-supplied item — homeowners love picking their own appliances. When appliances are client-supplied, your responsibility is rough-in to spec (gas line, electrical circuit, plumbing connection) and final connection only. Price it that way, and document in writing what you're responsible for and what you're not. If the refrigerator doesn't fit the opening because the homeowner ordered the wrong size, that's not your labor cost.

When appliances are GC-supplied, you're taking on procurement risk, delivery coordination, and warranty liability. Mark them up accordingly — 15–25% is standard, with the markup reflecting not just margin but the coordination overhead of managing appliance procurement on a timeline.

5. Rough and Finish Trades

Kitchen remodels almost always involve electrical (adding circuits for appliances, under-cabinet lighting, recessed lighting), plumbing (sink rough-in, dishwasher connection, ice maker line), and often HVAC (range hood venting, reconfigured duct runs if the layout changed). If the kitchen is older, budget for panel work — a kitchen with a gas range, dishwasher, garbage disposal, microwave, and refrigerator needs multiple dedicated circuits, and older panels often need a subpanel or circuit additions.

Tile work (backsplash, flooring) is the finish trade most commonly estimated too low. Material costs are easy to calculate; labor for complex patterns, odd-shaped spaces, and high-end materials is harder. On a standard backsplash (linear tile, simple pattern), tile installation runs $8–$15/sq ft installed. On custom tile with a herringbone pattern and marble field, it can run $25–$45/sq ft installed.

Site Visit Protocol: What to Look at Before Writing the Number

Never bid a kitchen remodel without a site visit. Photos don't show you what's behind the walls. Client descriptions of "just a cosmetic update" regularly turn into gut renovations once the demo starts.

Here's what I look at on a kitchen site visit:

Panel and electrical — Open the panel. How old is it? Is it full? Does it have dedicated circuits for major appliances, or are they sharing with other loads? Older panels (Federal Pacific, Zinsco, or any panel from the 1970s) are often a required upgrade when you're doing significant kitchen work — a fact that needs to be in the estimate, not a surprise.

Plumbing supply and drain — What size supply lines? Is the drain at the right height for the proposed sink configuration? If the layout is changing, what does it take to move the drain? A drain move that requires opening the floor or the ceiling below adds $1,500–$4,000 to the plumbing cost and usually a week to the schedule.

Walls and ceiling — Are the walls square? Are the ceiling heights consistent? Out-of-square walls add labor to cabinet installation. Inconsistent ceiling heights create problems with upper cabinet runs. Check for any previous water damage or staining — it indicates a source that needs to be addressed before you put new finishes on top of it.

Ventilation — Is there an existing range hood? Where does it vent — interior recirculation or exterior? If the homeowner wants exterior venting and there's currently none, that's a penetration, duct run, and cap — budget $800–$2,500 depending on distance and obstacles.

Flooring transition — Is the kitchen floor being replaced? If yes, what's underneath the current floor? A tile floor on top of a subfloor on top of another layer of old linoleum on top of the original wood subfloor is common in older homes and adds demo time and potential subfloor repair costs.

Document your site visit with photos. Use them in the estimate notes to show the client you saw what you're pricing.

Pricing Contingency and Managing Client Expectations

Kitchen remodels are high-emotion projects. The homeowner has been living with this kitchen for years and has a clear vision of what it should look like. When the job takes longer than expected or costs more than the original estimate, it lands differently than it would on a commercial project. Managing expectations before the contract is signed is as important as the estimate itself.

Transparent allowances instead of hidden contingency

I recommend breaking out allowances explicitly in the estimate rather than embedding contingency in line item prices. "Cabinet allowance: $14,000" tells the client exactly what you're planning to spend on cabinets — and if they want something different, you can price the change before the contract is signed rather than after. Hidden contingency that gets released as profit feels good on easy jobs and creates conflicts on hard ones. Transparent allowances with written terms for what changes them are cleaner for everyone.

What to put in writing before demo starts

• Material selections (every finish, every fixture) confirmed in writing with model numbers or supplier specs
• Appliance delivery dates and responsibility for coordination
• Change order process: all scope additions require written approval and price agreement before work proceeds
• Hidden conditions clause: conditions discovered during demo that require additional work will be priced and approved before proceeding — work does not stop, but changes are documented and signed off
• Lead times and their impact on schedule: if the cabinets are 10 weeks out, the project doesn't start in 4 weeks

Builders who establish this framework before the contract is signed have significantly fewer client disputes mid-project. Builders who defer these conversations "until we see what we're dealing with" have the same conversations later, but under worse conditions — mid-job, with money spent and pressure from both sides.

For related context on how the initial client conversation sets the tone, see the post on construction client onboarding — the kitchen remodel conversation is a specific application of the same principles.
