Estimate deck staining by surface type and condition, with preparation and railing work separate from deck-board area. Define the selected product and limits of old-coating removal.

THE SHORT ANSWER

Estimate deck staining by surface type and condition, with preparation and railing work separate from deck-board area. Define the selected product and limits of old-coating removal.

The worked project in this guide is 320 sq. ft. accessible deck . It uses an original fictional job to explain the estimating decisions, with a matching deck staining PDF example (https://quicklyestimates.com/en-us/samples/deck-staining-estimate/). Replace the example inputs with your measurements, supplier quotes and labor costs.

1. Inventory every surface

Measure walking boards, stairs and railings separately. The 320-square-foot deck area does not automatically include 90 linear feet of railing detail.

2. Assess current finish

Record peeling coating, bare wood and damaged boards. This sample allows limited sanding, not a complete strip or carpentry repair.

3. Confirm stain selection

Identify product, color and application requirements before ordering. The fictional material allowance does not represent universal coverage.

4. Plan access and handoff

State furniture movement, weather window and when the selected product can be used again based on its instructions. Include protection and cleanup in the quoted scope.

A worked deck staining calculation

Walking-surface application is 320 sq. ft. × $1.65 = $528. Railing application is 90 linear ft. × $4.20 = $378.

The complete example contains 7 lines totaling $2,208.00 before any tax or markup. These are deliberately stated example prices, not a survey, regional price recommendation or offer to perform the job.

To set your own selling price, review direct costs and decide how you will cover overhead and profit. For example, adding 20% to a $1,000 cost gives $1,200; it does not produce a 20% gross margin. Use the approach you intend consistently, and avoid adding a second markup to rates that already include it.

Before you send the estimate

- Measure deck, stairs and railings.
- Record coating condition and board repairs.
- Select stain product.
- Agree furniture, access and weather assumptions.

Example scope boundary: No board replacement, structural repair, full coating removal, furniture moving or guaranteed color match to aged wood.

Review the client name, location, validity date and all calculations. Tax is not included in this example; determine the correct treatment for the actual work rather than copying a sample percentage.

Common questions

Does deck staining include cleaning?

Only when listed. This sample includes a measured cleaning line and limited sanding allowance.

Can railing be included in deck square footage?

Railing is better measured and described separately because its detail work differs from walking boards.
