Four questions, and a planning range that moves as you answer them, with every step of the arithmetic printed underneath it, so you can check the number instead of trusting it.
01The planning range
The range is live from the first paint, built from typical choices that are labelled assumed until you change them. Nothing is hidden behind an email address, and nothing here is a bid.
02Where the numbers come from
Every remodel calculator on the internet produces a number. Almost none of them will show you the constants behind it, which is the only part that tells you whether to believe it. Here are ours, and here is the arithmetic they sit inside.
01
Each project and finish level carries a fixed amount for design, demolition and mobilisation, plus a rate per square foot for the trade work. Additions carry no base at all: on an addition, permits are their own cited line.
02
The age of the house scales the base and the trade work, because how much a house costs to open up scales with how much of it you open. Flat allowances (structural work and permits) are added afterwards and are never multiplied.
03
The bottom always rounds down and the top always rounds up, at a step that grows with the size of the job. If the arithmetic ever returns a band tighter than 25%, the page widens the top until it is not.
| Project and level | Project base | Trade work per sq ft | At the typical size |
|---|---|---|---|
| Kitchen: refresh | $2,500 to $4,700 | $120 to $320 | 150 sf → $20,500 to $53,000 |
| Kitchen: mid | $5,000 to $10,000 | $234 to $600 | 150 sf → $40,000 to $100,000 |
| Kitchen: high | $5,850 to $12,950 | $320 to $845 | 150 sf → $53,000 to $140,000 |
| Bath: refresh | $1,500 to $4,000 | $125 to $195 | 50 sf → $7,700 to $13,800 |
| Bath: mid | $3,000 to $8,000 | $250 to $400 | 50 sf → $15,500 to $28,000 |
| Bath: high | $4,100 to $11,000 | $325 to $535 | 50 sf → $20,000 to $38,000 |
| Addition: basic finish | None | $135 to $265 | 400 sf → $54,000 to $108,000, permit allowance included |
| Addition: matched finish | None | $180 to $350 | 400 sf → $72,000 to $142,000, permit allowance included |
| Addition: high-end finish | None | $250 to $490 | 400 sf → $100,000 to $198,000, permit allowance included |
Every figure in the last column is what the calculator shows for a house built in 1990 or later with no walls, plumbing or electrical moved.
These are our own numbers, and we would rather say so. The kitchen, bathroom and addition rates are our 2026 pricing for Reno and Sparks work, not a national survey with a local label on it. The mid level is our own figure for each project, and the refresh and high-end levels are set in proportion to it. A ground-floor addition and a second-storey addition carry the same rate here. What a second storey asks of the house underneath (new posts, beams or footings along the load path) decides where in the range it lands, and the walkthrough and the engineer’s drawings settle that.
What this page does not price. A whole-home remodel has too many moving parts for four questions, so that number comes from a walkthrough, not from this calculator. Nor does it price a window, siding or door job on its own, which is not work we quote.
03From a range to a bid
The range above is the first, and the only one that needs nobody to visit your house.
Scope-level arithmetic against our own Reno and Sparks pricing: enough to size a budget conversation, or to find out the project is bigger than the budget. You get a range and the arithmetic behind it
Somebody stands in the room. We measure, look at the panel, find where the plumbing runs, and name what cannot be assessed until something is opened up. You get a conditions list, including the unknowns
Room by room, trade by trade, with allowances named for what you have not chosen yet. This is where a range collapses into a number. You get a written scope with named allowances
Line items, not a lump sum, with a draw schedule tied to milestones. Free, and yours to take to another contractor and compare line for line. You get a line-item estimate you can compare
04What the range leaves out
A calculator that only tells you what it includes is telling you half the story.
05Why the arithmetic is on the page
This website is new. There is no star rating on this page, no review count, no project count, no award badge and no years-in-business figure, because there is not yet a record on this site to point at. Those are exactly the numbers every contractor site prints and almost none of them source.
So we publish the constants instead: the base and the square-foot rate for every project and finish level, what they give at a typical size, and the order the arithmetic runs in. All of it is above, and you can take any row of it to another contractor and ask whether it is reasonable.
The same logic governs the range itself. A single figure would be easier to sell and impossible to defend. A contractor who will not narrow a number before they have seen the house is telling you something useful about how they will behave later.
06Questions about the number
Including this one. If a calculator cannot answer all five about itself, that is the answer.
Accurate enough to decide whether to keep going, and not accurate enough to sign. The kitchen, bathroom and addition rates behind it are our own 2026 Reno and Sparks pricing at the finish level you selected, so it should tell you whether your project is a twenty-thousand-dollar conversation or a two-hundred-thousand-dollar one. What it cannot know is your house: the framing behind the drywall, the state of the service panel, how far the plumbing has to travel. Those are found on a site walk, and they are the difference between a range and a bid.
Because one number would be a guess wearing a suit. Two houses of the same size with the same scope land far apart on labour, access, condition and selections, which is why we price this work as a band rather than a point. We also widen the band rather than narrow it: the bottom rounds down, the top rounds up, and if the arithmetic ever returns a band tighter than twenty-five per cent the page widens the top until it is not.
It is carried on additions only, and it covers the building-permit fee itself for a Reno or Sparks address. It leaves out impact fees and utility connection charges, which the jurisdiction sets independently and which can be a large number on a project that adds bedrooms. It also leaves out plan-review revisions if the design changes after submittal. Treat it as a placeholder in a budget: the real figure comes from the published schedule for that jurisdiction, once we know the parcel and the scope.
Moving something that is fixed in place: taking out or relocating a wall, moving plumbing supply and waste lines, or relocating electrical service and circuits. It does not mean adding an outlet or moving a light. We carry it as one allowance rather than costing a header you have not shown us yet, because until a framer opens the wall nobody knows whether it is carrying load, and a wall that is carrying load costs several times what a partition costs to remove.
Because more of what we find is already known to be different. Pre-1980 houses in Reno and Sparks tend to carry undersized electrical service, non-standard framing dimensions, and materials that have to be handled and disposed of under their own rules once they are disturbed. This page carries that as a fixed uplift on the base and the trade work: ten per cent for a house built in the eighties, twenty per cent for one built before 1980. It deliberately does not multiply the flat allowances, because a permit fee costs the same whatever year the house went up.
07Send us the configuration
Everything you selected travels with this form: project, size, finish level, the age of the house, and which figures you set versus which ones the page assumed for you. Nobody asks you to repeat it, and the office starts from what you actually chose.
Monday to Friday, 9:00 AM to 4:00 PM. A person answers, and it is somebody who has been on a job site. The form goes to the same place, one business day behind the phone.
We will call you back within one business day, starting from the scope you built rather than from scratch. If you need us sooner than that, call (775) 200-0648 now: Monday to Friday, 9:00 AM to 4:00 PM.
