Fencing & decking
Fence Staining Cost Calculator
Prices staining a fence, where the area is both sides and the timing matters more than the product.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Hours times crew times rate plus materials and the call-out. The area is the part estimates get wrong: a fence has two faces, and unless only one side is being done the square footage is roughly double the length times height. Pickets with gaps add edge area that a sprayer covers and a brush does not, which is why application method changes both time and material use. Prep is a real line too, since stain applied over dirt, mildew or a weathered grey surface does not bond and comes off in sheets.
What moves the number
- Whether one side or both, which halves or doubles the area.
- Application method, since spraying is fast and uses more material while brushing is slow and works it in.
- Prep required, as cleaning and brightening an older fence can take as long as the staining.
- Overspray protection, because plants, paths and a neighbour's property all need covering when spraying.
Where this one goes wrong
New pressure treated timber is usually too wet to take stain, and applying it too soon means the stain sits on the surface and fails early. The common guidance is to let it dry out, which can be months rather than weeks depending on climate, and a simple water bead test tells you more than the calendar. Mill glaze on smooth new boards is the related problem and needs a clean or a light sand to break. On an older fence, going straight to stain without cleaning off mildew and weathered fibre wastes the material. And when spraying near a boundary, overspray onto a neighbour's car or plants is a genuine liability rather than an inconvenience.
Before you quote
- Test whether new timber is dry enough to accept stain before starting.
- Clean and, on an old fence, brighten before applying anything.
- Mask and protect for overspray, including on the neighbour's side.
Questions
About this calculator
How soon can a new fence be stained?
Usually not straight away. New pressure treated timber often holds too much moisture to accept stain, and applying it early means it sits on the surface and peels. Drying can take months depending on climate. A water bead test on the boards is a better guide than a fixed waiting period.
Does staining cover both sides of the fence?
Only if you are paying for both. A fence has two faces, so doing both roughly doubles the area and the material. Many jobs stain only the owner's side, which is a legitimate choice but should be explicit in the quote to avoid a disagreement later.
Spray or brush?
Spraying is far faster and reaches picket edges and gaps that a brush misses, at the cost of using more material and needing careful masking. Brushing works the stain into the wood and gives better penetration on weathered timber. Many jobs spray then back-brush, which gets both.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 20 h |
| People needed | 1 |
| Labour rate charged | $78 |
| Parts and materials | $2,000 |
| Call-out or diagnostic fee | $95 |

What comes out
| Result | Value |
|---|---|
| Estimated total main result | $3,655 |
| Labour | $1,560 |
| Before tax | $3,655 |
| Sales tax | $0 |
About $3,655: $1,560 of labour, $2,000 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $39 | $2,875 |
| $59 | $3,275 |
| $78 example above | $3,655 |
| $117 | $4,435 |
| $156 | $5,215 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
