Deck questions Alachua County homeowners ask

Material sets the bracket and everything else moves you inside it. Installed pressure-treated pine generally runs somewhere around twenty to forty-five dollars a square foot, cedar higher, capped composite and PVC higher again, and tropical hardwood highest. Those figures include the framing under the surface. Height off the ground, stair count, access for a machine, and how far the joists have to span all move the number within the range.

Usually because they are not the same deck. Different framing material and treatment ratings, different joist spacing, different footing sizes, different fastener systems, and different assumptions about whether the deck is attached or freestanding all produce different numbers for the same finished appearance. Comparing quotes means comparing the frame, not the boards, which is why a quote that names the framing material and the footing approach is worth more than one that does not.

Yes, and so is the visit. Somebody comes out, walks the yard, looks at the wall the deck would attach to, and puts a written price together. There is no obligation attached to it.

Deposits are normal in this trade, and so is a payment schedule tied to stages of the work: some at the start to cover material, some at milestones, and a balance at completion. What matters is that the schedule is written into the contract with the stages defined, so it is clear what has been paid for at any point.

A well-built one that suits the house generally helps, and there is a reason for that in this climate: usable outdoor space is a real feature here rather than a seasonal one. What does not help is an oversized deck that dominates the yard, a deck with an obviously failing structure, or one built without a permit where the record does not match what is standing. The last of those becomes a problem at closing rather than during ownership.

A deck attached to a house is structural work and should be treated as permitted work. Which office depends on the address rather than the mailing town: properties inside the city limits go through the City of Gainesville Building Division, and properties in unincorporated Alachua County go through Alachua County Growth Management. Because thresholds and exemptions differ by jurisdiction, the reliable move is to ask the office that covers the address before design is finalised.

The county describes it in stages: a pre-application screening for zoning and environmental compatibility, then the permit application, then plan review against the Florida Building Code by licensed examiners, then permit issuance with a notice of commencement, then staged inspections, and finally sign-off. The recorded notice of commencement has to be provided before the first inspection can happen, which is the step that most often holds a job up.

The Florida Building Code, Residential, which is the residential volume of the state code. Exterior decks are covered in Section R507, which sets out how footings, posts, beams, joists, decking, and the ledger connection to the house are sized and put together. The ledger connection and its lateral load requirements are the parts of that section that matter most, because that is where an attached deck fails when it fails.

Alachua County Growth Management publishes design wind speeds by risk category, with most residential construction at 130 mph, and it states that no part of Alachua County is in a wind-borne debris region. For an open deck that changes little. For a roof, a pergola, or a screen enclosure it changes a great deal, because those are surfaces the wind can lift, and the connections from the top of the structure down to the footings are what resist it.

Florida licenses construction contractors through the Construction Industry Licensing Board within the Department of Business and Professional Regulation. A Certified Residential Contractor is licensed for one, two, and three family residences and, in the words of the statute, accessory use structures in connection with them, which is where a deck sits. Florida Statutes section 489.103 exempts work of a casual, minor, or inconsequential nature under an aggregate contract price of $2,500, but that exemption does not apply where the work is part of a larger project, where a job is split up to get under the figure, or to anyone who advertises as a contractor. Most real deck projects are well past $2,500.

Yes. The Department of Business and Professional Regulation publishes a licence lookup, and a licence number can be checked for category, status, and expiry in a couple of minutes. Established local companies expect the question and have the answer ready.

The Gainesville land development code includes decks in its definition of impervious surface, which means a large deck can interact with lot coverage limits on a small lot. The numeric limits depend on zoning district, so the practical step is to confirm the coverage and setback figures for the specific parcel with the city before the deck is sized rather than after.

Framing around a tree is normal and generally produces a better deck than removing it. Where the design would require removal, Gainesville regulates the removal of larger trees through its urban forestry program and unincorporated Alachua County runs its own tree permitting, so that becomes a permitting question before it becomes a construction one. Confirming it early is free; discovering it late is not.

Composite and PVC do not feed decay fungi, do not splinter, and remove the stain-and-seal cycle, which in a humid climate is a genuine saving of time. They cost more up front and, in dark colours in unshaded sun, they get hot. Treated pine costs less to build and needs cleaning and re-coating on a rhythm. Both are reasonable. The wrong choice is the one made without knowing which trade was being accepted.

Dark composite in full unshaded sun in July gets hot enough that most people stop walking on it barefoot. That is physics rather than a brand defect. Two things change it: a lighter colour, which makes a real difference, and shade over the deck. On a treeless west-facing lot, colour selection is a performance decision.

Preservative-treated lumber is sold in use categories, and the material rated for above-ground use is not the material rated for ground contact. Posts, anything set in or near the soil, and stair stringers touching the ground need ground contact rated material. Using above-ground material at grade to save money is the most common reason a Florida deck frame is soft at the base while the boards on top still look fine.

Modern preservative treatment chemistry contains copper, and copper in contact with plain steel accelerates corrosion. That is why hot-dip galvanised or stainless fasteners and connectors are specified for treated lumber. Using ordinary screws and hangers on a treated frame produces rusted connections and rust staining down the boards within a few years.

Yes. Preservative treatment penetrates from the outside, so a saw cut exposes untreated wood in the middle of a treated board. Field-applied preservative on cut ends before the piece is installed takes seconds and closes off the easiest route in for decay. It is a small step that separates a careful frame from a fast one.

Composite contains wood flour bound in polymer, usually with a hard cap. PVC has no wood content at all, which means nothing in it for fungi to feed on. PVC is lighter, tends to run slightly cooler than a comparable dark composite, and generally costs more. Both go over the same treated frame and both have manufacturer instructions that dictate joist spacing and gapping.

There is no frost depth in Florida, so depth is set by what is under the yard rather than by a number. Alachua County lists buried land-clearing debris, decayed stumps and large roots, and poor compaction around utility lines among the common causes of subsidence around houses, and a footing landing on any of those has nothing to bear on. Holes are dug until they reach undisturbed material, which is why depth varies across one lot.

Attached is normal and completely reliable when the ledger is bolted properly and flashed so water cannot get behind it. Freestanding avoids the wall penetration entirely at the cost of an extra beam line and posts. On a slab-on-grade house with no band joist to bolt into, on stucco, or where the wall assembly is awkward, freestanding is often the better structure rather than a compromise.

Flashing is the metal that goes above a ledger and tucks up behind the wall covering, so water running down the wall passes over the ledger rather than behind it. Without it, every rainstorm sends water into the joint between the ledger and the band joist. In a climate with a thunderstorm most summer afternoons, an unflashed ledger rots the structural wood inside the wall quietly for years before anything shows.

Sometimes, and only after the frame has been opened up and checked. It has to be structurally sound, at the joist spacing the new board requires, and free of rot at the ledger, the joist ends, and the post bases. Putting a surface with a twenty-five year warranty on a frame that has ten years left is a false economy, and a contractor who checks properly will tell you which you have.

A straightforward single-level deck is usually a week or two of site time. Design, material lead time, the permit, and the weather sit around that. Between June and September afternoon storms come through almost daily and framing days get planned around them, so most projects run a few weeks from signed quote to finished deck.

The drier part of the year is easier for everyone. Work moves faster without a daily storm, the ground is workable, and if the deck is wood, the finish can go on without waiting for a dry window. That said, decks get built here year-round, and the wet season affects the schedule more than the quality of the result.

More often than the product label assumes, because the label was not written for this much sun and humidity together. Horizontal surfaces in full exposure wear fastest, rails and skirting last longer. The practical test is water: when it stops beading on the boards and starts soaking in, the finish has stopped working.

Algae and mildew colonise a surface that stays damp, and a shaded deck under canopy in this humidity dries slowly between storms. It is not a defect in the material and it happens to wood and composite alike. Washing it off with a cleaner suited to the surface handles it, and improving airflow and keeping the gaps between boards clear slows how fast it comes back.

Native subterranean termites occur throughout Florida according to the University of Florida extension service, so the exposure is real everywhere in the state. Preservative treatment is intended to protect against insect attack and decay, which is why treated lumber is standard here. The vulnerable spots are untreated field cuts, untreated trim, and anywhere wood stays in contact with damp soil.

Push hard on the guard rails, since a rail that flexes is the most common serious defect on an older deck. Look for staining or soft trim where the deck meets the house, which points at a ledger without flashing. Check the base of every post at the concrete line. And walk the stairs, which take more load and more water than anything else. Anything soft enough to take a screwdriver is worth a proper look.
