Deck or porch build Outdoor space built to last
A deck or porch build adds outdoor living space on footings, framing and decking, often attached to the house. The boards you choose shape the look and upkeep, but the footings, the flashed and bolted ledger connection, and the railings are what decide whether the structure is safe and passes inspection.

1What deck or porch build involves
A deck starts below ground. Footings usually need to reach below the local frost line so the deck does not heave in freezing weather, and their size depends on the load and soil. Posts sit on the footings and carry beams, which carry the joists. When a deck is attached to the house, it hangs on a ledger board that must be bolted or lagged into the house’s rim joist, not just nailed, and flashed so water does not get behind it. Failed ledgers are a leading cause of deck collapses.
Framing is usually pressure-treated lumber rated for ground contact where it is near soil, with fasteners and hangers rated for treated wood so they do not corrode. For the walking surface, pressure-treated wood is the least expensive and needs regular sealing, cedar and redwood look warmer but also need care, and composite or PVC decking needs less maintenance but costs more. Composite boards often need closer joist spacing than wood, which affects framing.
Many codes require guardrails when a deck surface is more than about 30 inches above grade, along with limits on baluster spacing and rules for stair risers, treads and handrails. A covered porch adds a roof, which adds weight to the footings and must be tied into the house roof and flashed, and it may need its own gutter. Before any digging, call 811 to have underground utilities marked. If you want lights or outlets outside, plan the electrical work before the decking goes down.
How the work usually goes
- Design and permit drawingsThe size, height, stairs and materials are set, and drawings are prepared for the permit, which many places require for attached or raised decks.
- Utility locate and layout811 is called to mark buried lines, and the footing locations are staked out.
- Footings and inspectionHoles are dug to the required depth, footings are poured or set, and many areas inspect them before framing.
- Ledger and framingSiding is removed where the ledger attaches, the ledger is flashed and bolted, and posts, beams and joists are installed with rated hardware.
- Decking, stairs and railingsDecking boards are installed, then stairs, guardrails and handrails are built to local code.
- Roof and final inspectionFor a porch, the roof, flashing and gutters are completed, and the final inspection is scheduled.

3Common mistakes
- Nailing the ledger to the houseNails alone can pull out under load. The ledger should be bolted or lagged to the rim joist following local code and flashed above to keep water out.
- Shallow footingsFootings above the frost line can heave and crack in winter. Ask how deep the footings will go and whether they will be inspected.
- Mixing the wrong fastenersTreated lumber can corrode standard fasteners. Use hangers and screws rated for treated wood or stainless steel where needed.
- Skipping the permitAn unpermitted deck can cause problems when you sell or file an insurance claim. Get the permit and inspections done as the work goes.

5Questions
What happens when I call?
Your call to 804-566-7669 connects to an independent local contractor. Describe the project, ask your questions, and decide whether you want a quote. Calling does not commit you to anything. iLikeToFix earns a referral fee when a call connects; here is how that works.
Is composite decking worth it over wood?
Composite and PVC decking cost more up front but usually need only cleaning, while wood decks need regular sealing or staining and can splinter or rot. Composite can get hot in direct sun and often needs closer joist spacing. Many homeowners pair composite boards with a pressure-treated wood frame. Your budget, climate and how much upkeep you want decide the choice.
Do I need a permit to build a deck?
Often, yes. Many places require permits for decks attached to the house, decks above a certain height and decks over a certain size, and covered porches almost always need one. Some low, freestanding decks may be exempt. Requirements vary by city and county, so check with your local building department before you finalize the design.
How long does a deck last?
It depends on materials, climate and upkeep. Pressure-treated framing that is kept dry and properly fastened can last for decades, while decking boards may wear out sooner. Composite boards resist rot but the framing under them still ages. Regular inspection of the ledger, posts, stairs and railings is the key to knowing when a deck needs repair or replacement.
Can a new deck attach to any house?
Not always. The ledger needs to attach to a solid rim joist, and some houses have brick veneer, cantilevered floors or other conditions that make that hard. In those cases a freestanding deck with its own beam and posts next to the house is common. A contractor can check what is behind your siding, and if you replace siding at the same time, see siding replacement.
