On average, a pressure treated wood deck costs $6 per square foot for materials, or between $12 and $18 per square foot installed. Pressure-treated wood (PT) is used on almost 75% of all decks in the US today. Chemically treated under pressure, it is fabricated to make the wood more resistant to mold, insects, and rot.
Disadvantages
The materials cost to build a deck with natural wood is between $3 and $15 per square foot with most homeowners spending $6 to $8 per square foot on average. Wood decks are beautiful and a top-choice for homeowners, however, they require more maintenance such as staining and sealing regularly. Here are the most common woods used for decking:
The most common type of natural wood used in deck building is the redwood from California. A redwood deck costs between $15 and $21 per square foot installed, and around $7 per square foot for just the materials. Redwood is just a little more per square foot than pressure-treated wood.

The addition of some steps will make a nice transition from the yard onto the deck. Depending on the size of the yard, one set may be sufficient, although you may choose to add the steps on either side of the deck.

---|---|
2 Steps | $110 – $165 |
3 Steps | $100 – $140 |
4 Steps | $140 – $190 |

Depending on the material used in building your deck, the average cost to install deck railing is $20 per linear foot. Normally a railing will not be on all four sides of the deck because one of the sides of the deck will be along the house. For a 42”-high handrail, one 2’ x 4’ horizontal top rail, and one 2’ x 6’ placed on the edge directly below the top rail, prices with balusters are:
Deck Railing Material | Average Cost |

The average cost to build a screened in porch on an existing deck is about $4.50 per square foot. This would bring you to a total of $600 for a small porch with basic materials up to $3,510 for a large wrap-around porch with high-end materials.
As a budget alternative, you can also choose to install a privacy netting screen. This is available to the consumer in 15’ x 3’ lengths and is almost 3 feet high. Generally, each panel will run around $20, will still need deck posts to tie to at each end, and will typically be attached to a top rail with screws and washers through grommets.

The average cost to add a hot tub to a deck is between $3,000 and $8,000 depending on the size, features, and model you choose. Depending on the number of people you want to accommodate in the hot tub; the number of jets per person; how long you want the product to last; the type of inner shell; and features like drink holders, colored LED lighting, etc., you will see a range of prices:

Entry Level | $2,000 – $4,000 |
Mid Level | $5,000 – $8,000 |
High End | $9,000 – $12,000 |
Luxury | $13,000 – $15,000 |
For the hot tub installation, you can simply set the hot tub right on top of the deck, or, if you have a slightly raised portion of the deck, it can be set down into a cutout. If the hot tub is going to be recessed, then some form of entry will need to be created to provide access for any maintenance that the hot tub pumps or electrical setup might need.
Depending on the type of shower you want to install–allowing you and your family to rinse off after using the hot tub or pool–and the distance from the nearest water line, your costs will be:

The average price to build a roof over your deck, or add pergola framing is between $0.70 and $1.30/sqft. Include $40 to $50 for supporting posts and concrete, and an additional $2.60 per square foot for flat asphalt roof covering. Another option is a manual deck cover which costs $500 to $1,500 or $1,700 and up for a motorized cover.
The average cost to install deck skirting is between $25 and $30 per square foot. Adding a skirt can finish out the look of the deck from your walking surface down to the ground and protect that space from large rodents.
The finished product will look like a privacy fence–with little to no gap between the boards–or it will be more like a trellis with the wood in either a diamond or square configuration. A complete absence of gaps will rule out the space becoming home to rodents or snakes, while the trellis option is more suited to being a visual addition.
With a natural wood deck, annual maintenance, repairs, and rebuilding is part of the game. With lots of upkeep, your wood decking can last 25 to 40 years before you need to replace. However, not maintaining your deck drastically reduces its lifetime down to 10 to 15 years. Pwsafe 3 0 – secure password management across devices.
Plan ahead for maintenance and deck repair costs, to include:
Maintenance & Repair | Average Cost |
---|---|
Damaged deck boards | $1,280 |
Loose deck stairs | $150 – $300 |
Missing deck nails | $5 – $10 |
Mold, mildew, and rot | $200 – $500 |
Damaged deck railing | $400 – $500 |
Termite and pest treatment | $100 – $300 |
Stain and seal | $3.50/square foot |
The average cost to sand, stain, and seal a deck is $1 to $3 per square foot. If you only have a small area that needs to be repaired, you can buy the sealant and stain and complete that portion of the project in your own time.
You should strive to reseal your deck annually. An average wood sealer costs about $20 per gallon and can easily be applied yourself.
On average, deck removal costs between $5 and $10 per square foot depending on the size and condition of the old deck. If you have a multi-level, built-in seating, or railing, removal prices will increase. An average 12x12 deck that consists of 144 square feet costs between $720 and $1,440 to remove.
If you’re tired of walking out your back door and having nothing decent outside to relax on, never mind host a BBQ or enjoy a stint in the hot tub, a deck can meet your outdoor living space needs.
Build one level, or include some raised portions; stretch it the full width of the back of the house or contain it to the area by the back door. No matter how large you go, make sure it meets your home improvement needs.
The main thing you need to choose before you start is the size of the deck. Standard advice is to make a deck a minimum 12’ by 12’ to make it a useable space for an average size family.
Many home builders will include an upgrade of a small 10’ x 10’ deck, but many people either regret going with one so little, or they upgrade before the home and deck are built.
You may elect to have one or two raised portions on the deck and possibly add a hot tub, which will increase the deck’s visual appeal, cost, and the overall value of your property. Websnapperpro 2 0 download free. Another option is to continue the deck to a second floor.
To get an idea of the size that fits your plan of use, look up the average sizes of furniture for the number of people you want to entertain. If you plan on having a dining section on the deck, then allow around 3’ around that table. Add square footage for any firepits, butane heaters, grills, or other accessories.
In general, a deck will be built no more than two inches below the bottom of the door used to access the deck.
Types of decks:
A high-elevation deck with a space under it less than eight feet tall could be used for storage for lawnmowers and yard equipment. If the space is at least eight feet high, then you could create an additional living area with a deck floor and ceiling leaving a balcony for the top, which will add an additional cost per square foot.
Check with your local governing authorities and homeowner’s association, to see what regulations and building codes you need to adhere to, and to see if you need a building permit. Some restrictions are created to regulate the minimum distance between your deck and a well, a septic tank or its drain field, and even a neighbor’s house.
Because the deck will increase the value of the home, it will also raise your property taxes. That amount will depend on the total cost of the project and your local property tax rate. Have a tax assessor come and inspect the deck once it’s built. It is not uncommon to be notified of any changes in your tax estimate while they are at your property.
Policies will already allow for coverage of an additional deck when it is attached to your home, just like it would cover damage to a garage or any other attached structure within the covered hazards portion of the policy. While there are some differences between states, according to the Insurance Information Institute, most homeowner insurance policies cover standard hazards from weather damage, fire, and other damage.
Professionally installed decks will almost certainly increase the value of the home. No matter if the housing market is up or down, the addition of a deck generally translates to a higher sales price for your home. In a survey conducted in the Remodeling magazine:
