We restained 47 decks in Sarasota last year. Only 9 of them were on schedule - meaning the homeowner called us before the stain failed. The other 38 had waited too long, and those decks needed restoration work that cost significantly more than simple maintenance would have.
How often should you stain a deck in Florida? The honest answer is: sooner than you think, and more often than what you read online.
Why Florida Changes Everything
Those timelines you find on deck stain labels and home improvement websites come from somewhere other than our climate. When a manufacturer says their stain lasts 3 to 5 years, they're testing in moderate conditions - seasonal sun, occasional rain, reasonable humidity.
Florida delivers year-round UV exposure at intensities that rank among the highest in the country. Our humidity never lets up. Summer brings daily afternoon storms that saturate surfaces, followed immediately by intense sunshine that bakes them dry. We don't get the winter dormancy that gives deck finishes in northern states a break.
Compare our conditions to somewhere like Ohio. A deck in Ohio faces maybe six months of serious UV exposure, cold winters that pause the weathering cycle, and significantly lower humidity. The same stain that lasts 4 years there might give you 2 years here. That's not the product failing - it's just what Florida does to exterior finishes.
What Determines Your Restaining Schedule
The biggest factor is sun exposure. A deck that faces south or west and gets full sun all day lives the hardest life. Semi-transparent stain on that surface needs attention every 1 to 2 years. Semi-solid might stretch to 2 to 3 years. Move that same deck under a screen enclosure or pergola, and you might get 4 to 5 years before restaining.
The type of stain matters just as much. Semi-transparent stains let more wood grain show through, which looks beautiful but means less protection on the surface. They wear faster than semi-solid stains that provide more coverage. Solid stains offer the most protection but hide the wood entirely - they're essentially exterior paint at that point.
Stain quality creates dramatic differences in longevity. Budget clear sealers from the home improvement store might protect for 6 to 12 months before breaking down. Move up to quality semi-transparent with UV inhibitors and trans-oxide pigments, and you're looking at 2 to 3 years. Premium semi-solid stains can push 3 to 4 years even in full sun exposure.
Your wood species affects things too. Pressure-treated pine is the most common deck material around Sarasota, and it takes stain well with standard maintenance schedules. Cedar has natural oils that affect how stain penetrates - generally good retention once it absorbs properly. Tropical hardwoods like ipe are so dense they barely accept stain at all, which is actually fine because they don't need it for protection the way pine does.
How you use your deck creates variation across the surface. The stairs and main walkways wear faster than perimeter areas. Where you place furniture sees less wear than open traffic lanes. Entry points from the house take more abuse than quiet corners. Some decks need full restaining on schedule while others can get by with touching up high-wear zones between complete applications.
The Water Test That Tells You When
Forget calendar schedules. The water test tells you exactly what your deck needs right now.
Sprinkle water across several spots on your deck - not just one area, but multiple locations including sunny zones and shaded corners, high-traffic lanes and quiet spots. Watch what happens for about 30 seconds.
If water beads up and sits on the surface like it would on a waxed car, your stain is still doing its job. Check again in a few months.
If water absorbs slowly, sitting for several seconds before soaking in, you're approaching the window where restaining makes sense. Start planning.
If water absorbs immediately, soaking into the wood like a sponge, you've waited too long for simple maintenance. The wood is now exposed to weather damage, and restoration will cost more than maintenance would have.
Different areas of your deck will give different results. The section that gets morning shade might still bead water while the south-facing rail cap has gone completely porous. This variation is normal and helps you understand which areas need priority attention.
What You See When Stain Is Failing
Visual indicators tell their own story beyond the water test.
Color fading is the first sign that UV rays are winning. If your deck looked rich brown when stained and now looks washed out, the pigments have degraded. This is aesthetic at first, but it means protective qualities are diminishing too.
Gray weathering indicates the wood itself is breaking down. The stain has failed enough that UV rays are now hitting raw wood fibers. Gray wood is damaged wood - it hasn't reached disaster territory yet, but it needs attention soon.
Bare wood showing through means the stain has worn away completely in spots. These exposed areas are absorbing water, expanding and contracting with humidity changes, and developing the conditions for rot.
Surface texture changes tell you about structural degradation. Rough grain means wood fibers are lifting as the protective finish fails. Splintering indicates deeper damage. Soft spots suggest moisture has penetrated and decay may be starting.
Mold and mildew growth happens when protective stain can't keep moisture out of the wood anymore. Florida humidity guarantees mold will find any opportunity to establish itself. Surface mold cleans off easily, but mold that's had time to penetrate requires more aggressive treatment.
Maintaining Your Deck Between Stain Jobs
Simple habits extend your stain's life significantly.
Sweep weekly at minimum. Leaves, pine needles, and organic debris hold moisture against the wood, accelerating stain breakdown and promoting mold. Five minutes with a broom prevents problems that take hours to fix later.
Trim vegetation back from the deck edges. Plants touching the deck trap moisture and block air circulation. That shaded corner near the overgrown hedge is probably the first place you'll see mold.
Move furniture periodically. Items sitting in the same spot indefinitely create moisture traps underneath while the exposed areas wear differently.
Address mold spots immediately when you see them. Mix one part bleach to three parts water, apply to the affected area, let it sit for 15 minutes, then rinse thoroughly. Catching mold early keeps it from spreading.
Fix drainage issues that send water pooling on the deck surface. Standing water accelerates every kind of damage. If you have areas that stay wet after rain, address the drainage before your next stain job.
The Economics of Proper Timing
A homeowner in Lakewood Ranch was paying about $900 every 3 years for maintenance restaining. Regular cleaning, a fresh coat of stain, and the deck looked great year after year.
Her neighbor waited longer between services - 5 to 6 years instead of 3. Each time, the deck needed restoration rather than maintenance. Gray wood needed sanding, damaged areas needed replacing, and the staining itself required more product because the thirsty wood absorbed so much. Each visit cost $2,500 or more.
Over a decade, the first homeowner spent roughly $3,000 on deck maintenance. The second spent more than double that, and her deck looked worse between services.
Proper timing isn't about spending more on your deck. It's about spending less by addressing conditions before they become expensive problems.
Seasonal Planning for Florida Decks
Spring inspection makes sense as your annual checkpoint. Walk the deck in March or April, perform the water test in multiple locations, note areas showing wear or mold, and schedule work if needed. This timing catches any damage from winter and gets you ahead of the rainy season.
Summer requires attention even when you're not restaining. This is prime mold season. Sweep regularly, address any mold spots you find, and keep the surface clear of debris. Don't schedule staining during summer - daily afternoon storms and high humidity create miserable conditions for coating work.
Fall through early spring is your ideal window for actual staining. Humidity drops, rain becomes less frequent, and temperatures stay moderate. If your spring inspection revealed work needed, now is when it happens.
Professional Maintenance Programs
Some homeowners prefer scheduled professional oversight rather than DIY monitoring. A basic annual service includes inspection, cleaning, mold treatment, and minor touch-ups. Comprehensive programs add full restaining when due, small repairs, and priority scheduling.
The advantage of professional programs is consistent monitoring by people who know what they're looking at. We catch problems early, schedule work at optimal times, use products matched to Florida conditions, and maintain documentation of your deck's condition over time.

Frequently Asked Questions
How many years does deck stain last in Florida?
Quality deck stain typically lasts 2-3 years in Florida's full sun exposure. Semi-transparent stains may need recoating every 1-2 years, while semi-solid and solid stains can last 3-4 years. Covered decks extend this to 3-5 years. Florida's intense UV, humidity, and rain cause faster stain degradation than northern climates.
How do I know when my deck needs restaining?
Signs your deck needs restaining include: water no longer beads on the surface (absorbs instead), significant color fading, gray or weathered appearance, visible bare wood showing through, mold or mildew growth, and rough or splintering texture. Annual water-drop tests help catch stain failure before major damage occurs.
Can you stain a deck too often?
Yes, over-staining can cause problems. Applying stain before the previous coat has worn sufficiently leads to buildup, tackiness, and uneven appearance. Penetrating stains need the wood to be receptive. Wait until water absorption indicates the wood is ready, or you'll waste product and create adhesion issues.
