Short answer: most decks in Spring Hill cost $30–$65 per square foot installed in 2026. Pressure-treated wood sits at the bottom of that range, capped composite at the top, and pool decks, multi-level designs and covered structures price above it. Here's how the numbers actually break down — the same way we walk through them at your kitchen table.
Spring Hill Deck Pricing By Material
Pressure-treated pine: $30–$45 per square foot. The workhorse of Florida decks. A 12x16 (192 sq ft) PT deck typically lands between $6,500–$9,500 including permit, footings, framing, decking and a standard wood railing. It needs sealing every 12–18 months in our sun, but nothing beats it on upfront price.
Capped composite (Trex, TimberTech): $50–$65 per square foot. The same 12x16 deck runs $11,000–$16,000 depending on the board line and railing choice. You're paying for the end of maintenance — no staining, no sealing, no rot, with 25–50 year board warranties. Our wood vs composite guide runs the 10-year math.
Hardwoods (ipe, cumaru): $55–$75+ per square foot. Spectacular, dense, naturally rot-resistant — and priced like it. A niche choice in Spring Hill but worth seeing samples if you want the look nothing else matches.

The 6 Factors That Move Your Price
1. Size — but not linearly. Bigger decks cost less per square foot because permits, mobilization and footings spread across more area.
2. Height. Ground-level platforms are the cheapest structure. Every foot of elevation adds posts, bracing, stairs and code-required railings.
3. Railings. The sneaky budget line. Basic PT wood railing is included in most base pricing; upgraded aluminum, cable or composite systems run $40–$90 per linear foot.
4. Site conditions. Spring Hill's sandy soil actually digs easily, but sloped lots (common toward Brooksville), tree roots, and tight access all add labor.
5. Features. Built-in benches, planters, privacy screens, lighting, pergolas — each adds real money and real value. We price them as line items so you can choose.
6. Permits and engineering. Hernando County permits with wind-load engineering typically add $500–$1,200 to a project. Every quote we write includes it; not every contractor's does, so compare carefully.
What About Cheap Quotes?
If a number comes in dramatically under the ranges above, something's missing — usually the permit, the footing depth, or the hurricane hardware. An unpermitted deck becomes your problem at sale time and after storm claims. The Hernando County permit process isn't optional, and it isn't where to save money.
