Skill
5 Easy The most challenging part: locating and pulling the old face nails.
Pull the Nails
These square-edged deck boards were face-nailed to the joists. To remove a board, Tom looks for a telltale row of nailheads, then uses a cat’s paw to pry out each nail in the board. If a nail is missing a head, he uses nail-pulling pliers, as shown.
Remove the Broken Board
With the nails gone, Tom jams a pry bar under the break, levers up one end of the board, and pulls it out. He does the same at the other end. Scoring the paint along the joint on the board’s edges eases removal.
Make the Cleats
To support the ends of the new board, Tom cuts a pair of cleats out of the cracked board, making each three times longer than its width. He squeezes construction adhesive on the ends of the unpainted face, as shown.
Install the Cleats
Tom snugs a cleat, adhesive side up, under the neighboring boards and drills pilot holes through the deck and into it. He secures it with stainless-steel trim-head screws, as shown. The cleat at the opposite end goes in the same way.
Cut and Fasten the New Board
Tom uses clear Douglas fir because it’s more stable and holds paint better than a cheaper wood. He cuts a single board to length, beds it in adhesive at each joist and cleat, and secures it at those locations with two hot-dip-galvanized 8d nails, placed 1/2-inch from the edges.
Set the Nailheads
Using a nailset, Tom taps the nailheads a hair below the board’s surface. They’ll be invisible after the wood gets a coat of oil-based exterior primer and two coats of deck paint.
Inspect Damage
The first step is to look for damages. Identify what needs to be repaired and make notes. The effects of weather conditions can cause damage to the porch so make sure you look thoroughly. Another important thing to look for is rotting wood. You can figure out easily if the wood is rot by inserting a screwdriver into it.
Clean Up
Washing the porch is an essential part of the repair. If you regularly wash your porch, you might not need to make a lot of effort in repair. However, if your porch had not been washed, you might want to start now. In case you have painted the porch, you will require a paint remover. Make sure that you wear gloves while dealing with paint.
Sanding the Porch
You can sand your porch using a belt sander, palm sander, or a sanding sponge. But before you begin, remember that wood that is used to build a porch is usually soft and can be damaged if you used these tools very roughly. Therefore, be careful while sanding.
Oiling or Staining the Porch
This is the final step to repairing a porch. You need to coat the entire porch with porch oil or wood stain. Porch oil is used to protect the wood from sun damage and deterioration. Apply it generously on the porch and wait for about a week for it to dry. You may reapply it as well for a second coat.

Where is Ken Brown's porch?

Set the Cutting Depth
Set the cutting depth of a circular saw to the thickness of one of the porch flooring boards, instructs This Old House. Cut two lengthwise lines through one of the rotten boards so you can pry it out. The lines should be about an inch apart.
Pry Up the Center Piece
Pry up the part of the board between the cut lines up with a pry bar. It may crumble as you're prying, which is good, because that makes it easier to remove. Pry out rest of the board out toward the space you created after the center piece is gone.
Pry the Rest of the Boards
Pry out all the rest of the rotten boards by working away from the space created by the one you removed, says Today's Homeowner. If the joists aren't rotten, you may not have to remove all the floorboards – just the ones that have rotted. If any of the joists are rotted, however, pull up all the floorboards so you can replace the joists.
Remove the Joists
Remove any rotted joists by removing the fasteners holding them to the rim joists. If they are held with metal joist hangers, pull the nails holding them to the hangers with a cat's paw pry bar. Leave the hangers in place.
Cut New Joists
Cut new joists from pressure-treated lumber with the same dimensions as the lumber you removed. Cut each joist to length with a circular saw, drop it into the hangers and fasten it with 1-inch galvanized nails.
Install New Floorboards
Install new floorboards to replace the ones you removed. If you only removed some of them, you have to replace them with the same type of boards as the ones that remain on the porch. You may have to special-order them from a lumberyard or mill them yourself with a table saw.
Add Your Finishing Touches
Finish the floor as necessary. If you paint it, spread a coat of exterior primer first, and then use porch floor enamel for the topcoat. Spread both the primer and the paint with a wide paintbrush.
