painting or staining a wooden deck

Overview of Pressure Washing and Deck Staining

Removing dirt from the wood grain with pressure washing, aka power washing, let’s penetrating stain work deep into the wood to protect and beautify. The combination improves the looks of the deck and its durability. Depending on the aesthetics of your home, paint might be a preferred option.

The downside is that this process must be repeated every few years to slow the decline all wood decks are subject to. Another option is to replace your wood deck with a low-maintenance, high-durability material like composite decking.

Deck Repair Cost Factors

Our cost range of $2.15 to $4.25 per square foot would yield estimates of $516 to $1,020 for a 12’ x 20’ (240 square foot) deck. That’s quite a range. Using HomeGuide’s numbers, the cost is a little lower at $360 to $960. The Homewyse estimate is more in line with ours at $495 to $1,185.

If you have evaluated your deck’s condition, these factors will help you estimate your potential cost more accurately. They’ll prevent surprises when you get deck cleaning and staining estimates from local contractors.

  • The Size of the Deck – Of course the larger the deck, the higher the cost, but the cost per square foot drops a bit as deck size increases. This is because the crew is already on site, and travel/overhead expenses are spread over more square feet of deck. The Sample Project Costs below consider this factor.
  • Whether the Deck Has Rails and Stairs – Adding deck railing and stairs increases deck cost by up to 30%. Cleaning and staining railing has a similar impact on cost compared with decks without railing or stairs.
  • How Dirty it Is – Very dirty, stained decks cost more to wash than those that have been regularly maintained.
  • Whether Repairs are Required –  Minor repairs like fastening loose balusters or stair treads, or removing a little wood rot and filling the space, are included in this cost estimate. More substantial deck repairs like replacing deck boards are not.
  • Deck Shape – A rectangular deck is the easiest shape to power wash and stain. When a deck has a non-rectangular shape or has multiple tiers, cost will be higher.
  • The Quality of the Stain or Paint – As you can see from the retail costs below, high-quality penetrating stain and paint costs quite a lot more than cheaper products.
  • Pressure Washer Cost – If you don’t own a power washer, your options are to borrow, rent ($) or buy ($$$). Don’t rule out the “buy” option; you’ll find plenty of uses for a power washer around the house including cleaning the driveway and the vehicles that use it.
  • Whether you Have Tools – Little things like brushes, rollers, roller handles and paint/stain trays add up when putting together an itemized supplies list like the one below.
  • Time of Year – Costs are higher in spring and summer when demand for deck maintenance is high. If weather permits during the offseason, you can save money during those months.
  • Water Rates – If you have metered water, consider the 350 to 500 gallons of water it takes to wash average-size decks.
  • Who Does the Work – You’ll save on labor costs if you pressure wash and clean your deck, though if you have to rent equipment, some of the savings will be lost.

Deck Repair vs Deck Replacement

Deck repair costs quite a bit more per square foot than building a new deck.

How do you know it is time to replace the deck rather than repairing it? These factors provide clues:

  • Whether the damage is caused by general wear, tear and aging of the deck or by a one-time event. If the deck is generally in good condition but a limb fell on it or the turkey fryer got out of control, then repair is probably the cost-effective choice. Just consider whether you’ll be OK with the different looks of materials of different ages, especially if it is wood.
  • The age and overall condition of the deck. If a large section of the deck is failing and repair costs amount to a third or more of the cost of a new deck, then replacement should be considered. After all, the remaining areas of the deck will continue to age, and the process seems to speed up as the years go by.

Cost of Disposal for Damaged Decking

Often, a deck contractor will ask if you want the cost of disposal included. It’s certainly the most convenient route, but might not be the cheapest.

Whether your remove the damaged decking yourself, you might save on disposal costs in one of two ways. First, if it is a small amount of material, you might be able to get rid of it a little at a time in your weekly garbage pickup, if you have it. If it’s plastic, vinyl or metal, your local recycling facility might take it.

If you have to pay for disposal, consider a Bagster from Waste Management or a dumpster with capacity appropriate for the amount of material – decking and other stuff you want to get rid of.
