Overview

Decks are popular outdoor building projects. They increase living space by adding a room made specifically for relaxation and enjoyment. A deck is a great place for outdoor reading or just sitting and watching a sunset.

A DIY deck saves the cost of labor and material markup, cutting the total cost by at least half. Here’s how to build a DIY inexpensive deck.

Materials

Start by estimating the cost of your deck. Use pressure-treated lumber instead of cedar or redwood and use stain to change the color or let it age to a silver-gray tone. Some nails and screws are made specifically for use with pressure-treated lumber. Bolts, lag bolts, and brackets should all be galvanized.

Ledger Board

The deck attaches to the house with a joist called a ledger board which is installed before the footings and posts. The ledger is the starting point for the rest of the deck layout. Attach the ledger to the house with 1/2-by-4 1/2-inch lag bolts and washers. Be sure to install a piece of “Z” flashing under the house siding that sits on top of the ledger.

Footings and Posts

Lay out your footings with mason lines and stakes using the ledger as a reference. Dig the footings 10 inches in diameter and make them 6 inches deeper than local codes require so you can add some gravel to the bottom for drainage.

Mix your concrete to save on the cost of premix. When you pour the footings, place a J-bolt in the concrete for adjustable post brackets.

Footing and Post Layout - DIY Inexpensive Deck Plans

The footings support the posts, which support the beams which support the rest of the framing. Use a post level to keep the posts plumb and your mason lines to position them correctly.

Beams

Beams sit on top of posts for the greatest strength and support the rest of the joist frame. Attach beams to posts with the post-to-beam brackets. Most beams are two pieces of joist lumber nailed together.

Joists

Joists attach to the ledger on one side and the end joist on the other. The end joist sits on top of the end support beam. Place joists every 16 inches on the center and attach them using joist hangers on both ends.

Rail Posts

Plan railing posts so they are equal distances apart which makes baluster spacing the same around the deck. Attach railing posts in the corners using 1/2-inch carriage bolts through the end and rim joists. Middle posts use two bolts through the rim joist. Railings must be either 36 or 42 inches high, depending on the height of the deck.

Decking

Using 2-by-6 lumber for the decking saves a bit on the cost of deck boards. The decking runs parallel to the ledger board across the joists. You’ll need to make cut-outs to fit around the posts and space the boards 1/8-inch apart. Attach the decking to the joists with 2 1/2-inch deck screws.

Railings

Railings consist of four parts: The posts, 2-by-4 top, and bottom rails, and balusters. Optionally, you can add a cap rail for a more finished look. Cut the top and bottom rails so they fit between the posts and attach with 2-by-4 brackets. Install 2-by-2 balusters evenly spaced on the rails.

Stairs

Stairs with railings and handrails don’t need to complicate a DIY inexpensive deck project. Measure and calculate the number of steps and step risers. Mark and cut the stringers, then install them using stringer hangers or 2-by-12 joist hangers.

Add posts, stair treads, railings, and handrails to finish. Read about deck stair measurements, layout, and plans with railings and handrails.
