Deck builder in Largo and Seminole, FL

Composite and wood decks in Largo, Seminole, Pinellas Park and the Belleair beaches.

We build composite and wood decks in Largo, Seminole, Pinellas Park, Belleair and Indian Rocks Beach, the middle of Pinellas County between St. Pete and Clearwater.

Building a deck in Largo and Seminole

  • City or county permits: Largo and Pinellas Park run their own building departments. Many Seminole-area homes are in unincorporated Pinellas and go through Pinellas County. We check your address and pull the right permit. See deck permits.
  • Ranch homes on slabs: Most homes here sit close to the ground, which makes ground-level composite decks off a slider a common, affordable project.
  • Beaches next door: Indian Rocks Beach and the Belleair beaches get salt air, so we switch to stainless hardware and PVC or capped composite there.
  • Older pine decks: Many 1970s and 1980s homes have original pine decks that are rotting at the posts. See deck replacement.

Deck services in Largo

  • New composite decks: Trex, TimberTech, Fiberon, Deckorators and MoistureShield, on concrete footings with framing at 12 inches on center.
  • Deck replacement: Tear-out of old pine decks, new footings and framing, and new boards. Common on 1960s–1980s ranch homes on slabs.
  • Deck repair: Soft boards, rotted posts, loose ledgers and wobbly railings when the rest of the deck is sound.
  • Railings and stairs: Aluminum, cable and composite railings, plus stairs wrapped to match.
  • Pergolas and covers: Shade over all or part of the deck.

Choosing boards for a Largo deck

Most of Largo is away from salt spray, so standard capped composite with coated hardware is the best value. Around Indian Rocks Beach and the Belleair beaches, where decks stay damp and shaded, capped composite or PVC beats pine by a wide margin.

Permits and approvals in Largo

Deck permits here come from the City of Largo or Pinellas Park building departments, or Pinellas County for unincorporated Seminole-area homes. Villa and 55-plus communities usually need association approval. Here's how we handle it:

  1. We measure and draw a site plan and construction details.
  2. If you have an HOA or association, we send them the drawings and material samples first.
  3. We submit the permit and answer any review comments.
  4. The inspector checks the footings, the framing and the finished deck. We're there for each visit.

More detail is in our deck permit guide.

How long a deck takes

Permit review usually takes two to four weeks. Once the permit is issued, most decks take one to two weeks on site. Bigger, raised or multi-level decks take longer.
