Calculator Use

The deck staining cost calculator is a comprehensive tool designed to help homeowners and contractors estimate the total expenses associated with refinishing a wooden deck. By inputting specific dimensions and material preferences, you can generate a realistic budget for your project.

To get the most accurate results from the deck staining cost calculator, ensure you have measured your deck area correctly and checked local labor rates.

Deck Area (sq. ft.)
The total surface area of the floorboards, stairs, and railings you intend to stain.
Price per Gallon
The retail cost of the stain you have chosen. High-quality solid stains often cost more than semi-transparent ones.
Labor per sq. ft.
The rate charged by professional painters or handymen. Standard rates typically range from $2.00 to $5.00 per square foot depending on location.

How It Works

The deck staining cost calculator uses standard coverage variables to determine the quantity of stain required. Most wood stains cover approximately 200 to 300 square feet per gallon, depending on the wood's age and porosity. The formula used for our calculation is:

Total Cost = ((Area × Coats / Coverage) × Price per Gallon) + (Area × Labor Rate) + Prep Fees

  • Area: Measured in square feet.
  • Coats: Most projects require 2 coats for optimal protection.
  • Coverage: Set at a standard 250 sq. ft. per gallon for this calculator.
  • Prep Fees: Includes power washing, sanding, or chemical stripping costs.

Calculation Example

Example: A homeowner has a 400 sq. ft. deck and wants to apply 2 coats of premium stain ($50/gallon) using a local contractor who charges $3 per sq. ft. for labor, plus a $150 cleaning fee.

Step-by-step solution:

  1. Calculate total coverage needed: 400 sq. ft. × 2 coats = 800 sq. ft. total.
  2. Determine gallons: 800 / 250 = 3.2 (Round up to 4 gallons).
  3. Calculate material cost: 4 gallons × $50 = $200.
  4. Calculate labor cost: 400 sq. ft. × $3 = $1,200.
  5. Add prep fees: $150.
  6. Total Estimated Result = $1,550.00

Common Questions

How often should I use the deck staining cost calculator?

Decks should generally be restained every 2 to 3 years. Use the deck staining cost calculator whenever you notice the wood is no longer repelling water or the color has faded significantly, indicating it is time for maintenance.

Does the calculator include the cost of railings?

Railings are often the most time-consuming part of a deck project. When using the deck staining cost calculator, you should add roughly 20-30% to your total square footage to account for the extra surface area and labor involved in staining railings and balusters.

Can I save money by doing it myself?

Yes, by setting the Labor Rate to zero in the deck staining cost calculator, you can see the "Materials Only" cost. DIY projects usually save between 60% and 80% of the total project cost, though they require significant physical effort and time.
