Composite Decks in Alachua for Owners Who'd Rather Not Sand and Stain

A composite deck trades a higher price at the start for far less work later. The boards don't need sealing, they don't splinter, and the plastic shell that wraps most modern boards keeps out the moisture that rots wood. Under the shade trees and afternoon storms of North Central Florida, that shell is the main reason people pick composite.

What a composite deck can't do is fix a weak frame. The joists and beams under it are still pressure-treated lumber, so they get the same careful framing as any custom wood deck we build. Below is how the board types differ, what the frame needs, and what the price looks like. For everything else we build, start at the deck builders in Alachua home page.

Composite Deck Boards Alachua Homeowners Choose Between

Capped composite

Most composite boards sold today have a core of wood fiber and recycled plastic wrapped in a polymer cap on three or four sides. Trex, TimberTech and Fiberon all make capped lines at several price points, from basic solid colors up to boards with multi-tone grain and deeper scratch resistance. The higher tiers cost more but tend to hold color better in full sun.

PVC decking

PVC boards, such as the Azek line, have no wood fiber at all. They are lighter, resist moisture completely and generally run cooler underfoot than capped composite in a similar color. They cost more per board and can expand and contract more with temperature, so the gapping and fastening details matter.

Color and heat

Any dark board gets hot in July sun. Lighter grays and tans stay noticeably cooler than deep browns, which matters on a south- or west-facing deck where kids and dogs walk barefoot. We bring samples to the site visit so you can set them in the sun on your own lot and feel the difference.

Composite Deck Framing Built for North Florida Moisture

A composite surface hides the frame for good, which makes the frame the part to get right. Every board manufacturer publishes joist spacing limits, and we build to them: 16 in. on center for boards laid straight and 12 in. for diagonal or herringbone patterns. Stair stringers often need to be closer together than that, depending on the board, so we check the current installation guide for the exact product you choose.

• Ground-contact treated joists and beams. Composite boards hold moisture against the joist tops, so the lumber below needs the heavier treatment rating.
• Butyl joist tape over every joist and beam, sealing around each fastener and keeping standing water off the wood.
• Hidden fasteners or color-matched screws as the manufacturer specifies, with the right gap between boards for drainage and expansion.
• Matching fascia wrapped around the rim joists so the edge of the deck looks finished and the framing stays covered.
• Airflow underneath. Low decks need vents or open skirting so the frame can dry after a storm.

Composite Deck Cost in Alachua, FL

Composite runs about $40 to $60 per square foot installed, with most finished projects falling between $8,000 and $22,000. The board line you choose sets part of that, and the rest comes from height, railing, stairs and how complicated the shape is. Composite railing systems are a big line item on their own, so many people pair composite boards with aluminum rail to keep the total in check.

Composite Decking Under Alachua Shade Trees and Near Pools

Two settings around Alachua suit composite especially well. The first is the wooded lot: golf-course homes in Turkey Creek and the newer streets in Heritage Oaks often back onto oaks and pines that drop pollen, needles and tannin-heavy leaves. Capped boards wash clean where raw wood would stain and grow mildew. The second is the pool. Composite won't splinter wet feet, and our pool and multi-level decks page covers the extra details a deck near water needs.

Composite still needs a little care. A soft brush and deck cleaner once or twice a year clears pollen film and leaf stains, and a plastic shovel or leaf blower keeps debris from sitting in the gaps. Avoid metal-bladed scrapers and keep grill grease off the boards with a mat.

Composite Decking Over an Old Wood Deck

If you have an older wood deck and want composite on top, the existing frame has to pass a close look first. Old joists may be spaced too wide, notched, or soft at the tops where water has sat for years. Sometimes the frame can be reinforced and reused; often a full deck replacement costs less over time. We show you what we find and price both paths. The article on composite vs. wood in North Florida helps if you are still deciding on material.

Homeowners association rules matter here too. Many subdivisions limit deck colors or ask for samples with the application, so we provide the board name, color and railing details your board will want to see.

Composite Deck Details Worth Choosing Up Front

A few choices are hard to change once the boards are down, so we go through them at the design visit.

Gaps, ends and long runs

Composite and PVC boards grow and shrink along their length as temperatures swing between a cool January morning and a July afternoon. Manufacturers set end-gap rules based on the temperature when boards are installed. On long decks we often break the run with a perpendicular divider board so no single board spans too far, which also adds a nice visual line.

Fastener style

Hidden clips that grab grooved board edges leave a clean surface with no screw heads. Face screws with color-matched heads are faster and work on square-edge boards, which are often required on stairs and at the perimeter. Many decks use both.

Borders, inlays and lighting

A contrasting picture-frame border hides cut ends and frames the deck. Low-voltage lights in stair risers, post caps or the fascia need wiring routed before boards close up the frame, so plan them early even if you add the fixtures later.

Composite also works well on stairs and landings, and our deck stairs and railings page covers how stringers are spaced for composite treads.

Composite Deck Builders From Alachua to Lake City

We build composite decks well beyond Alachua's city limits. Newer homes in Jonesville often come with a small builder patio that a composite deck extends into usable space, and older homes around Lake City frequently trade a worn wood deck for boards that won't need another weekend of sanding. Each town has its own permit office, and we work with whichever one covers your address.
