Deck Building Tips from
ModernView Decking

From the simple to the extravagant, deck building takes time. There are many things to consider when building a deck, other than the size and complexity. There are codes to follow, permits to obtain, surveying, digging and pouring of deck footings. With ModernView Decking, you have one less thing to worry about, quality. As a leader in composite decking, we also make every effort to ensure that deck building with composite decking materials is as efficient as possible. With the following tips, you can achieve better results in less time and by spending less money.

 

Building Codes

After the location and design of your deck has been decided, make sure to check local building codes, regulations, and zoning restrictions before building your deck. A building permit may be required before deck construction can begin. This process may include submitting the plans or drawings of the proposed deck structure to a building inspector in the building department of your town. The inspector can inform you of any changes that need to be made in order to meet local codes and requirements. Once the plans comply, you will be issued a building permit.

 

Building Permit

Permits may only last for 3, 6, 9, or 12 months, so be sure you note the date to make sure it lasts through construction. The building inspector may also visit your deck site during construction to check the foundation and structure. You may also want to inform your neighbors that you are building a deck. If construction trucks are needed to access the deck building site, you may need their cooperation.

 

Surveying Procedure

Once the location and design of your deck has been approved or a permit has been obtained, the deck can be outlined using a simple surveying procedure known as the 3-4-5 Rule:

1. Stake a line 4' long parallel to the house wall. One end of the line is stake A, the other is stake B.
2. Connect a second line to stake A, run it perpendicularly to a point 3' away, and attach the line to stake C.
3. Finally, if the distance between stakes B and C is 5', then the corner is square and you can use stakes and string to complete the outline of your deck.

Remember, at this stage accuracy is critical to the success of your project.

 

Digging and Pouring Deck Footings

Once the planning and paperwork is complete, it's finally time to dig and pour the footings for your deck. Your composite deck needs to be sturdy, with its feet planted squarely on the ground and bolted to concrete footings that extend down to 6 inches below the frost line or whatever depth your local building code instructs. Before digging begins, check for pipes and power lines underground to avoid expensive damages.

 

Sizing Joists and Posts

The joist spans will vary depending on how far apart you space the boards of the deck. At 16 inches apart:

• 2x6 joists can span 8 feet
• 2x8s can span 10 feet
• 2x10s can span 13 feet

At 24 inches, 2x6, 2x8, and 2x10 joists can span 6, 8, and 11 feet respectively.

 

Determining Deck Patterns

Composite deck boards are typically installed at right angles to the joists; however, you can install the boards in a diagonal pattern or double the joists in a herringbone pattern. Whatever composite decking material or deck pattern you decide to use, it's best to leave spaces the size of about the thickness of a nail between the boards.
