Austin planning-cost guide
What deck surface work can cost in Greater Austin
Dated Completa project-price examples for deck washing, staining, sanding, and non-structural surface-board replacement in Austin.
Direct answer
Start with the scope—not an unsupported unit rate.
Deck square footage is a useful quantity for clearly defined surface work. Preparation method, finish system, board material, demolition, elevation, access, railing or stair scope, and hidden structural damage determine whether square footage supports a scope-based estimate.
Calculated examples
Every range keeps its exact scope attached.
The center figure is the dated project-price example for the work shown. The low-to-high range reflects uncertainty around that same scope. It is not a separate market average, checkout total, or promise that changed work will stay inside the range.
Project-price examples—not quotes or checkout totals
Each displayed figure is a dated, non-binding Completa project-price example for the exact work stated—not a contractor bid, offer, final quote, guaranteed price, or promise that a contractor will perform the work for that amount. Actual project prices can differ when the information provided, site conditions, current costs, contractor review, or scope changes. It is not the customer checkout total. If a project proceeds, checkout separately shows the contractor-reviewed project price, any applicable Customer Service Fee or payment-processing fee, applicable Sales Tax, and the total due before payment authorization. The accepted written project scope and any approved written changes control the final scope and price.
| Exact example | Included scope | Quantity basis | Project-price range |
|---|---|---|---|
| Wash and seal a 120 sq. ft. ground-level deck | A ground-level deck under 30 inches high with washing, basic sealer, application consumables, masking, and job setup; no sanding or stain-color change.
| 120 sq. ft. | $470–$636 Calculated project-price example: $553 Calculated unit price for this example only: $3.92–$5.30 / sq. ft. |
| Sand and stain a 230 sq. ft. deck | A ground-level deck under 30 inches high with sanding, semi-transparent stain, application consumables, masking, and job setup.
| 230 sq. ft. | $975–$1,320 Calculated project-price example: $1,148 Calculated unit price for this example only: $4.24–$5.74 / sq. ft. |
| Replace 120 sq. ft. of pressure-treated deck boards | Pressure-treated surface-board replacement on a simple rectangular, ground-level deck, including old-board demolition and disposal; the framing remains in service.
| 120 sq. ft. | $1,707–$2,310 Calculated project-price example: $2,009 Calculated unit price for this example only: $14.23–$19.25 / sq. ft. |
The effective unit rate is calculated from this complete example. It is not a transferable quote, checkout total, or unit-price promise for another job.
How quantity affects the estimate
A measurable base with the missing work added back.
For clearly defined surface work, the calculation uses measured deck area with the selected wash, sand, stain, or board-replacement system and the stated demolition and access conditions. A new structural deck requires a different project review.
What moves the number
The most important price drivers stay visible.
02
Material and finish system
Pressure-treated wood, cedar, and composite surfaces do not share one material, fastener, or coating system.
03
Elevation and access
Raised decks, second-story work, tight yards, stairs, and difficult material staging change labor and safety planning.
04
Surface versus structure
Replacing deck boards is not the same as repairing joists, beams, posts, ledgers, footings, guards, or a complete deck.
On-site review conditions
Some conditions should be inspected before price is confirmed.
These are not ordinary add-ons. They are conditions where photos and measurements may be insufficient to establish a project-specific scope and price.
Structural repair or new deck
Unknown framing, footings, ledger attachment, guard geometry, engineering, permitting, and site constraints require field review before pricing a complete build or structural repair.
Major rot or concealed damage
Surface measurements cannot prove that the supporting structure is sound. Unsafe or concealed conditions stay outside the published examples.
Common questions
How to read this guide responsibly.
- Do these examples equal the customer checkout total?
- No. They are dated, non-binding project-price examples for the stated work. If a project proceeds, checkout separately shows the contractor-reviewed project price, applicable customer or payment-processing fees, applicable Sales Tax, and the total due before payment authorization. The accepted written project scope and any approved written changes control the final project scope and price.
- Why does this guide not publish a new-deck price?
- New-deck and structural scopes should begin with field review because geometry, framing, footings, ledger attachment, guards, stairs, permitting, engineering, and access cannot be established by square footage alone.
- Can deck staining be estimated directly?
- It can support a real-time, scope-based estimate when area, surface condition, preparation, finish system, access, and exclusions are clearly stated. A contractor still confirms the project-specific scope and price before agreement.

Completa collects the project details that make a real-time estimate explainable. A matched local pro reviews the project-specific facts and confirms or adjusts the price before work begins.
