Hurricane Season Exterior Prep Guide
Hurricane season in Jacksonville runs June 1 through November 30, and every year it brings the same pattern: long stretches of punishing heat and daily downpours, punctuated by tropical systems that dump inches of rain in hours and throw wind gusts through every neighborhood from the Beaches to the Westside. No amount of exterior cleaning will hurricane-proof a house — anyone who tells you otherwise is selling something. But the condition of your gutters, roof, and yard in June has a genuine effect on how your home handles the other 95 percent of the season: the relentless rain, the saturated ground, and the mold bloom that follows.
Here is an honest exterior prep checklist, in priority order, based on what actually fails on Jacksonville homes during storm season.
Guide
1. Gutters and Drainage Come First
If you do one thing before hurricane season, make it this: get your gutters fully clear and flowing. Jacksonville's summer storms do not sprinkle — they unload. A gutter choked with oak catkins, leaves, and decomposed sludge cannot move that volume of water, and the overflow goes exactly where you do not want it: behind the fascia, down the siding, and pooling at the foundation.
What a proper pre-season gutter service includes: all debris removed by hand, downspouts flushed and checked for flow at every elbow (a clogged elbow is as bad as a clogged gutter), hangers checked for sag, and the outside of the gutters soft-washed so you can actually see their condition. While we are up there, we flag anything concerning — separated seams, pulling hangers, fascia starting to soften — so you know about it before a storm tests it.
Also walk your yard's drainage. If water ponds against the foundation after heavy rain, that is a grading or drainage issue no pressure washer can fix — but it is worth knowing before the season's biggest rains arrive, because saturated soil against a foundation is how crawl spaces flood.

2. Roof: Clear Debris, Check the Vulnerable Spots
Your roof takes the worst of every storm, and small pre-existing problems become big ones under hurricane-force wind and horizontal rain. Before the season, the roof should be clear of accumulated debris — pine needles, oak leaves, and branches that collect in valleys and against flashing. Debris holds moisture against the shingles, and in a major rain event it dams water where it should be flowing off.
A soft-wash roof cleaning in late spring does double duty here: it removes the debris and the black algae streaking (gloeocapsa magma), and it gives a professional set of eyes on the roof's condition. We flag lifted shingles, cracked flashing boots, and worn valleys when we see them — the exact failure points that turn a tropical storm into an interior leak.
One honest boundary: pressure washing does not fix a failing roof. If shingles are curling, granules are filling the gutters, or the roof is past 20 years, what you need is a roofer, not a wash. We will tell you that straight if we see it.

3. Yard Clutter Becomes Projectiles
This one is pure physics. In 70+ mph gusts, everything unsecured in your yard is a potential projectile — and your siding, windows, and screens are the targets. Before the season:
- Secure or store patio furniture, grills, potted plants, and yard decor. If it cannot be stored, it should be tied down.
- Trim dead limbs, especially over the roof and near the house. Big live-oak limbs are a job for a licensed arborist, not a DIY chainsaw afternoon — falling limbs kill people every storm season in Florida.
- Clear the areas around your home's exterior walls. Stacks of anything against the house trap moisture all season and become mold farms by August.
This is also the right time to pressure wash fences, sheds, and outbuildings — not for storm protection, but because you are about to spend five months barely looking at them, and going into the season clean means coming out of it with less established growth.

4. What Pressure Washing Can and Can't Do Before Storm Season
Honest accounting, because this matters:
What it CAN do: strip the mold, mildew, and algae that are already established, so they do not explode across every surface during the months of daily rain. Clean gutters and downspouts so the season's downpours actually drain. Clear roof valleys of debris dams. Give you a documented look at your exterior's condition — photos of your roof, siding, and drainage before the season are genuinely useful if you ever file a storm-damage insurance claim.
What it CAN'T do: make your home hurricane-proof, fix drainage grading, repair a failing roof, or stop storm surge. Anyone selling pressure washing as storm protection is lying to you.
The real value proposition is simpler: Jacksonville's storm season is five months of accelerated weathering. Going into it clean means the weathering starts from zero instead of from an already-established mold colony. Coming out of it, the cleanup wash is faster and cheaper.

5. After the Storm: The Cleanup Wash
Once a tropical system passes, the exterior aftermath is predictable: leaf and branch litter plastered against siding, mud splatter on the lower walls, roof grit in the gutters, and — within two to three weeks — a visible mold and mildew bloom on every shaded surface, fed by the saturated everything.
A post-storm cleanup wash is one of the highest-value services we do: debris cleared, siding and concrete washed, gutters flushed of storm litter. Two notes from experience:
- Document first. Before anything is cleaned, photograph any damage — lifted shingles, bent gutters, cracked siding, water intrusion marks. Your future insurance adjuster will thank you, and cleaning first can erase evidence you needed.
- Do not rush the wash the day after. Let standing water drain and the immediate debris settle. A week or two after the storm is the right window — early enough to stop the mold bloom, late enough that you are not washing mud that is still arriving.
If the storm was major, expect every pressure washing company in Jacksonville to be booked solid for weeks. Customers on a regular schedule get priority with us — one more quiet argument for being on a maintenance plan before you need it.
