Worth knowing
Re-siding exposes the wall, which makes it the cheapest moment to add exterior insulation, correct flashing, or replace windows. Doing any of those later means paying for access twice.
Siding over existing siding is possible with some materials and saves the removal line, but it hides the sheathing, adds thickness at every opening, and can trap moisture.
Pre-1978 homes may have asbestos-cement siding, which carries specific removal requirements and cost that this calculator does not model. Test before demolition.

Sheathing condition is invisible until the old siding comes off, and it is both the most common change order and a signal that water has been getting in for a while.

Methodology
How this calculator works
Working out the wall area
From a footprint and storey count we estimate perimeter as 4.2 times the square root of the footprint and multiply by nine feet of wall per storey. Gables add area that this misses on a steeply pitched house, so enter a measured figure if you have one.
Material is ordered with a 10% waste allowance. Siding waste is higher than it looks because every course has to start and finish at a corner or an opening.
Why sheathing is a separate line
The sheathing behind siding is what holds the fasteners and keeps the wall rigid. When it is rotten it must be replaced, and no amount of new siding compensates for it.
It is also invisible when the quote is written. We price it per 4x8 sheet at a share of the wall that you estimate, and set the contingency high enough that finding more is a budget event rather than a crisis. If a quote does not mention sheathing at all, ask what happens when they find it.
The opportunity cost of not doing more
Re-siding is the only time the wall assembly is open. Adding exterior insulation, correcting flashing, or replacing windows costs a fraction now of what it will cost later, because the expensive part — access — is already paid for.
Location and data
Where the numbers come from
Location is optional, and we only ask for a ZIP code or a state — never a street address. A ZIP code is matched to its state using published postal prefix ranges, and that state is used to look up labor and price rows in the tables below. If you leave it blank, or your ZIP cannot be matched, the estimate falls back to a national average and says so on the result.
Nothing you enter is transmitted or stored. The calculation runs entirely in your browser, and the only place your inputs appear is in the page URL, so you can bookmark or share a result if you choose to.

These are NOT published statistics. As with the interior material baselines, no public agency publishes exterior material prices at this granularity and proprietary construction cost databases cannot be reproduced. Every figure is material only, delivered to a metropolitan supply yard, before regional adjustment and before sales tax. Labor rates are crew-hours or per-unit production rates for a competent crew in normal conditions. See docs/data-sources.md for the full limitation statement.
These are the figures we chose rather than measured. For each one we record the range of values found across references, what we selected, and why — because an estimate you cannot interrogate is not much better than a guess. The 2 marked high risk are the ones most likely to be wrong and most consequential when they are.
Siding material per square foothigh riskmedium confidence+
Observed range
1.4 — 20 (typical 5.2)USD per square foot
Why this value
Sampled pricing spans $1.40/sq ft for builder-grade vinyl to $20 for brick veneer. Selected mid-band values per material. The eightfold material spread is compounded by labour, since the expensive materials are also the slow ones.
Applies to
United States. Stucco is materially cheaper in the Southwest where the trade is common; not modelled.
Known limits
Brick veneer and stucco are as much labour trades as material ones, and pricing them per square foot of material understates how much of their cost is skill availability.

Sheathing replacement per sheethigh riskmedium confidence+
Observed range
40 — 120 (typical 68)USD per 4x8 sheet installed
Why this value
CDX sheathing installed, covering 32 sq ft per sheet. Applied at a user-estimated damage share of 0%, 15%, or 40%. The most common change order on a siding job and invisible until the wall is stripped.
Applies to
United States.
Known limits
The damage share is guessed by the homeowner before anyone has looked behind the siding. Widespread damage usually indicates a long-standing water entry problem that should be diagnosed rather than covered, and the calculator cannot say that from a percentage.

Publicly advertised big-box and trade supplier pricing, sampled across several metropolitan markets; Published trade production-rate guidance and contractor estimating handbooks
Gables, dormers, bays, and changes of plane each mean starting and stopping courses. A boxy two-storey is the 1.0 case. Capped at 1.4 because beyond that the job is usually a custom-trim exercise rather than a siding one.
Applies to
United States.
Known limits
Self-assessed. Overlaps conceptually with the opening count, so a complex house with many windows may be double-counted slightly.

Observed range
18 — 140 (typical 55)USD each
Why this value
Wrapping and flashing per opening. Openings are where water gets in, so this is detail work rather than production work. A house with many small windows costs noticeably more to side than one with few large ones of the same glazed area.
Applies to
United States.
Known limits
Does not vary with opening size. A patio slider and a bathroom window are priced identically, which understates large openings.

Existing siding removal and disposalmedium confidence+
Observed range
0.4 — 3.5 (typical 1.5)USD per square foot
Why this value
Removal $0.60-$2.20/sq ft and disposal $0.25-$0.95/sq ft, modelled as separate lines because disposal cost tracks material weight while removal tracks fastener density. Vinyl comes off fast and weighs little; stucco is the opposite on both counts.
Applies to
United States. Tipping fees vary by county.
Known limits
Does not vary with the material being removed, only with area. Removing stucco is several times the cost of removing vinyl and the model prices them identically.

Multi-storey labour multipliermedium confidence+
Observed range
1 — 1.6 (typical 1.18)multiplier on labour
Why this value
Staging rather than ladders above one storey, and material lifted rather than carried. Selected values are conservative against the observed range because siding crews stage the whole elevation once rather than repositioning constantly.
Applies to
United States.
Known limits
Gable ends add height and area beyond the storey count, and the area model does not capture them on steeply pitched houses.

Why this value
Not currently exposed as a siding input, unlike exterior painting, because siding crews stage rather than working from ladders and are less sensitive to ground conditions. Recorded here so the omission is deliberate and visible rather than an oversight.
Applies to

Tight urban lots with no staging room are a real constraint that this calculator does not ask about at all.

Observed range
0.15 — 1 (typical 0.45)USD per square foot
Why this value
Weather-resistive barrier, seam tape, and window flashing. The high case reflects a fully adhered membrane rather than a mechanically fastened wrap. Cheap relative to the siding and the single most consequential layer for wall longevity.
Applies to
United States.
Known limits
Flashing detail quality varies enormously and is not capturable as a per-square-foot cost. Poor flashing at openings is the usual cause of the sheathing damage this calculator prices separately.

Observed range
0.6 — 4 (typical 1.8)USD per square foot
Why this value
Rigid foam board $0.90-$2.80/sq ft; insulated siding backer $1.30-$3.60. Re-siding is the cheapest opportunity to add exterior insulation because the wall is already open — adding it later means paying for access twice.
Applies to
United States. Value is climate-dependent and highest in the coldest zones.
Known limits
The energy saving is not quantified here, so the user sees a cost with no payback. Linking this to the climate dataset and the insulation calculator would make it a real decision rather than a line item.

Siding waste allowancemedium confidence+
Observed range
0.06 — 0.2 (typical 0.1)share of ordered material
Why this value
Higher than paint because every course starts and finishes at a corner or an opening. 10% suits a simple elevation; complex houses with many openings reach 20%. We ship 10% and let the complexity multiplier carry the labour side.
Applies to
Not regionally variable.
Known limits
Fixed rather than varying with the complexity input, so a complex house under-orders material even though its labour is correctly increased.

Cost factors
What changes the price most
Material
An eightfold spread from vinyl to brick veneer, and the slower materials cost more in labour too.
Sheathing condition
Priced per sheet, invisible until demolition, and the most common change order.
Storeys and complexity
Staging on every elevation above two storeys; gables and dormers slow every course.
Openings
Each window and door needs wrapping and flashing. Many small windows cost more than a few large ones.
Insulation
Optional, but far cheaper now than as a separate job later.
Asbestos
Not modelled. Pre-1978 cement siding may require specialist removal at significant additional cost.
Questions
Frequently asked
How much does it cost to replace siding?
+
For a typical 2,200 square foot wall area, vinyl commonly lands in the low five figures installed, fibre cement roughly 50% to 80% higher, and brick veneer several times that. Removal, sheathing repair, and trim all add on top. Enter your own details above for a state-adjusted figure.
Is fibre cement worth more than vinyl?
+
It costs roughly twice as much installed and buys a 45-year service life against 30, far better fire and impact resistance, and the ability to be repainted. In hail or wildfire regions the case is strong; in a mild climate on a house you plan to sell soon, vinyl is hard to argue against.
Can you put new siding over old?
+
With some materials, yes, and it saves the removal and disposal lines. The costs are that nobody inspects the sheathing, the wall gets thicker so every opening needs extending, and any moisture already trapped stays trapped. Most contractors will recommend full removal.
How long does siding replacement take?
+
One to two weeks for a typical single-family home, longer for fibre cement or brick, and longer again if sheathing turns out to need replacing. Weather governs more than crew size, since the wall cannot be left open through a storm.
Should I replace windows at the same time?
+
If the windows are near end of life, almost certainly. The flashing and trim work overlaps substantially, and doing them together avoids paying twice for the same detail. Our window replacement calculator prices that side.
