Seasonal Windows & Doors Care for Fort Lauderdale: Year-Round Homeowner's Guide

Seasonal Windows & Doors Care for Fort Lauderdale: Year-Round Homeowner’s Guide

Most seasonal home-care checklists treat Fort Lauderdale like it’s Minneapolis with better tans. They tell you to caulk before the first frost, check weatherstripping before the snow. That advice is useless here. In Fort Lauderdale, your windows and doors don’t fight winter – they fight a daily cycle of salt, humidity, and thermal shock that would destroy a Wisconsin window in under three years. This guide gives you the Fort Lauderdale-specific care schedule: what to do, when to do it, and why the advice you read on generic national sites gets it wrong here.

Quick Answer

Fort Lauderdale has two real seasons for window and door care: the dry season (November through May) and the wet season (June through October). During the dry season, inspect sealants, lubricate hardware, and clean salt deposits off frames. During the wet season, clear weep holes, check thresholds and sweeps, and verify impact-glass integrity before the first named storm. A dollar-bill test on your door sweeps and a visual sealant check twice a year will prevent most of the expensive failures we see in this market.

Why Fort Lauderdale Has Two Seasons, Not Four

The single most common cause of seal failure in Fort Lauderdale windows isn’t age. It’s the pressure differential that happens when a homeowner runs the AC at 72°F indoors during a 94°F, 90% humidity afternoon in September and then opens the house for a “cool” evening. That daily thermal cycling is roughly 30 times harder on sealants than anything a Wisconsin winter produces. The glass expands. The frame expands at a different rate. The sealant between them stretches, then relaxes, then stretches again – 365 days a year.

Add salt air from the Atlantic, which settles on aluminum frames and works its way into weep holes and hardware, and you have a maintenance profile that looks nothing like a four-season guide. In our experience replacing and installing windows across Fort Lauderdale – from Victoria Park to Rio Vista to Coral Ridge – the failures we see cluster around two things: ignored sealants and clogged weep holes. Both are preventable with a schedule that matches the actual climate.

The smart approach is to think in two blocks: the dry season (roughly November through May, when humidity drops and rain is less frequent) and the wet season (June through October, when afternoon thunderstorms, hurricane threats, and 80%+ humidity are the daily reality). Each season has a handful of tasks that take an afternoon or less. Do them, and you’ll add years to the lifespan of your windows in Fort Lauderdale and doors without spending a dime beyond basic supplies.

Dry Season Care (November – May): Sealant, Hardware, and Salt

The dry season is your maintenance window. The weather cooperates, humidity drops, and you can safely leave windows open while you work. This is when you inspect what the wet season did to your windows and doors, and get everything ready for the next cycle.

Sealant Inspection

Sealant – the caulk line where the window or door frame meets the stucco, wood, or brick of your home – is the first line of defense against water intrusion. In Fort Lauderdale, the sun bakes exterior sealants from April through September. UV exposure breaks down the polymer structure, and by October you’ll often find hairline cracks that weren’t there in March. Run your finger along the top sealant line first; that’s the surface that takes the most direct sun. Look for separation, cracking, or spots where the sealant has pulled away from the frame entirely.

If you see a gap wider than a credit card’s edge, you have a potential intrusion point. Water that gets behind the frame doesn’t drain – it sits against the rough opening and the housewrap, and in a climate with Fort Lauderdale’s humidity, that moisture rarely dries on its own. Recaulking a single window takes under an hour and typically runs $8 – $20 in materials if you do it yourself. Replacing rotted framing behind that failed sealant is a different conversation entirely, and it’s one you don’t want to have.

Hardware Lubrication

Window locks, sliding tracks, and door hinges all accumulate salt and corrosion in this coastal environment. Once a year during dry season, clean the hardware with a dry cloth, then apply a dry silicone lubricant (not WD-40 – it attracts dust and gums up over time) to:

• Sliding window tracks and rollers
• Locking mechanisms and strike plates
• Hinges on entry doors
• Crank mechanisms on casement windows

Most window installation work we do in Fort Lauderdale lasts 20-plus years if the hardware is lubricated annually. Skip it for three or four years, and salt corrosion seizes the mechanisms – locks don’t engage fully, sliders bind, and eventually something bends or breaks under force.

Salt Deposit Removal

If you live east of Federal Highway or within a mile of the Intracoastal, you’ll see a white, powdery film accumulate on aluminum frames – that’s salt. Left in place, it corrodes the finish and eventually pits the metal. During dry season (ideally in November and again in March), wash frames with a solution of warm water and a mild dish soap, using a microfiber cloth. Rinse thoroughly with clean water. We’ll cover the specific cleaning products for each frame material below, but the short version: no abrasive pads, no bleach, no ammonia on any frame type.

Wet Season Care (June – October): Storm Prep and Humidity Defense

The wet season is when Fort Lauderdale’s windows and doors earn their keep. From June 1 through November ends the hurricane season, but the daily reality of the wet months is afternoon thunderstorm cells, 80%+ humidity that starts before sunrise, and a storm-driven air pressure that actively pushes moisture against your exterior openings. Your job during these months is to make sure water has a clear path away from the structure and that your seals, sweeps, and thresholds are actually doing their job.

Weep Hole Clearance

Every window frame – whether it’s a PGT, CGI, ES Windows, or ECO Window Systems unit – has small weep holes along the bottom exterior edge. These are engineered drains that let water escape from the frame track when wind-driven rain blows into the sash. In Fort Lauderdale, weep holes clog with salt, sand, pollen, and insect debris. In our experience, eight out of ten window failures we see involve weep holes that are fully or partially blocked.

Check every window in the house monthly during wet season. Use a wire or a small brush to clear each hole. Pour a cup of water into the bottom track – if it drains freely outside, you’re good. If water pools against the interior lip, those holes are clogged and need attention. A clogged weep hole means water has no exit, which means it sits in the track and eventually migrates inward through the gasket line.

Threshold and Sweep Check

The gap between your door bottom and the threshold is the most common entry point for humid outdoor air in Fort Lauderdale homes. At 2 a.m., when your AC is cycling, that gap lets moisture-laden air slip into your conditioned space. It’s not enough to feel – it’s a slow, constant seep that raises indoor humidity, makes your AC work harder, and leaves the door face damp. We’ll show you how to find it below.

Post-Storm Inspection

After any significant thunderstorm, take ten minutes to walk the exterior of your home. Look for:

• Dented or cracked frames from wind-driven debris
• Water staining below windows or doors
• Leaves or debris packed into window tracks or weep holes
• Doors that now stick or bind – a sign the house shifted slightly or the frame absorbed moisture

Catch these issues in the first 48 hours and most are simple fixes. Let them go for a month and you’re looking at frame damage, molding issues, or a door installation that may not be salvageable.

The Dollar Bill Test: Finding the Gap You Can’t See

The gap that lets humid outdoor air seep into your home overnight is usually too small to see. But you can feel it – with a dollar bill. Here’s the method we use on every service visit in Fort Lauderdale, and it takes about five minutes per door.

1. Close the door fully and latch it.
2. Place a single dollar bill between the bottom of the door and the threshold.
3. Close the door on the bill, leaving half the bill sticking out on the interior side.
4. Pull the bill toward you slowly.

If the bill slides out with little resistance, the sweep or threshold is not making proper contact. That gap is your humidity leak. If the bill holds tight or takes noticeable effort to pull, the seal is functioning. Check the bill at three points along the threshold – left, center, and right. Doors settle unevenly over time, especially in South Florida’s sandy soil, and a door can seal perfectly on one side while leaving a gap on the other.

If you find a gap, the fix is usually a replacement door sweep (a strip of vinyl or rubber that screws to the bottom face of the door) or an adjustable threshold that can be raised slightly. Most sweeps cost $10 – $30 and install in fifteen minutes with a screwdriver. If the gap is uneven or the door itself has warped, that’s a door replacement conversation.

Run this test twice a year – once in May before the humidity settles in, and once in October after the worst of the wet season has done its damage.

What to Clean Your Frames With – and What Will Ruin Them

Different frame materials react differently to common household cleaners. What’s safe on vinyl will etch anodized aluminum. What works on fiberglass will cloud the factory finish on a Therma-Tru door slab. Here’s the material-specific breakdown for Fort Lauderdale conditions, where salt residue is the default film you’re cleaning.

Vinyl Frames

Vinyl – common on many PGT, CGI, and Mr-Glass windows – is the most forgiving material, but it’s not bulletproof. Use warm water with a few drops of dish soap. Avoid anything with bleach, ammonia, or solvent-based components; these break down the polymer structure over time and cause the white to yellow. Do not use Magic Erasers or anything abrasive; vinyl scratches easily and those scratches hold salt and grime. Dry with a microfiber cloth.

Aluminum Frames

Aluminum – found on ES Windows and many impact-rated lines – has an anodized or powder-coated finish that resists corrosion but is vulnerable to alkaline cleaners. Do not use bleach, Simple Green, Formula 409, or any degreasing agent. They dull the finish and leave white oxidation spots. Warm water, mild soap, and a soft cloth are all you need. For salt crust, soak the area with the soap solution for a minute, then wipe gently. On uncoated aluminum (rare but present on older Fort Lauderdale homes), this is even more critical – exposed aluminum oxidizes quickly in this climate.

Fiberglass Doors and Frames

Fiberglass – common on Therma-Tru entry doors – has a factory finish designed to look like wood grain. That finish is durable but not indestructible. Use water and mild soap only. No ammonia-based glass cleaners on the door slab, no bleach, no pressure washing at close range. Salt deposits from sea air should be wiped off with a damp cloth monthly during dry season; the longer they sit, the more they bond with the finish.

Wood and Clad-Wood Frames

If your Fort Lauderdale home has wood or aluminum-clad wood windows from the 1980s or early 1990s, you already know they’re high-maintenance in this climate. Clean with a barely-damp cloth and mild soap. Never let water pool on the wood. Check the exterior paint surface for cracks every six months – any exposed wood in this humidity starts wicking moisture immediately, and that moisture becomes rot and termite activity faster than you’d believe.

Low-E Glass: Why Ammonia Is Your Enemy

Low-E coating (low-emissivity – a microscopically thin metallic film applied to the glass surface) is the standard on energy-efficient windows in Fort Lauderdale, including units from ECO Window Systems and PGT. That coating reflects radiant heat back toward its source – back outside in summer, back inside during our brief winter cool snaps. It’s the reason a quality window can cut solar heat gain by 40% or more.

That coating has a vulnerability: ammonia. When you spray Windex or any ammonia-based glass cleaner on low-E glass, the ammonia reacts with the metallic coating. Over time – sometimes surprisingly quickly, given how frequently Fort Lauderdale homeowners clean glass during salt season – the coating degrades. The first sign is usually a hazy, iridescent smear that won’t wipe off. That isn’t dirt; that’s the coating breaking down.

Clean low-E glass with a solution of water and a tiny amount of mild dish soap, using a clean microfiber cloth or a soft squeegee. Wipe the interior-facing surface gently – that’s where the coating sits on most residential windows. Skip the paper towels (they’re made from wood pulp and can leave micro-scratches) and skip anything labeled “heavy duty” or “extra strength.” If you only change one cleaning habit this year, make it this one.

One more note: the same rule applies to any glass with a protective film or tint applied to the interior surface. If your Fort Lauderdale home has aftermarket window film for solar control, treat it exactly like low-E glass. No ammonia, no abrasives.

Pre-June 1 Readiness Walkthrough: The Westlight Checklist

Every June, before the first tropical system forms, we run the same readiness checklist on service calls across Fort Lauderdale. Homeowners ask what we’re looking at, and honestly, the whole thing takes under an hour. It’s the same checklist our technicians follow on callback visits – the things that fail most often in this climate, checked in order of how catastrophic the failure would be.

Step 1: Impact Glass and Door Integrity

If you have impact-rated windows and doors – PGT, CGI, or ES Windows units are common in Fort Lauderdale – check each unit for cracks, chips, or fogging between the panes. Impact glass can take a direct hit from wind-borne debris in the design pressure range it was tested for, but a pre-existing chip or crack compromises that rating. Fogging between panes means the seal has failed and the unit is no longer providing the full impact rating. Look at both the exterior and interior surface, and check the frame corners for any separation.

Step 2: Hardware Function

Operate every window and door in the house. Locks engage fully. Hinges move freely. Sliders glide without binding. French doors meet the threshold evenly. If anything sticks, squeaks, or won’t lock, that’s a pre-storm vulnerability in this climate – when winds hit 50-plus mph, a door that doesn’t latch securely can flex and fail even if the slab itself is impact-rated.

Step 3: Weep Hole Clearance

We covered this in the wet season section, but it bears repeating: clear every weep hole on every window. Do it now, before the wind starts driving rain horizontally. A single clogged weep hole on the windward side of your house is a water intrusion accident waiting to happen.

Step 4: Track and Threshold Drainage

Sweep out window tracks and door thresholds. Pull out the leaves, the sand, the dried insect casings. Water that sits in a track during a two-day rain event will find the gasket’s weak point. Keep the tracks clean and dry when the weather allows.

Step 5: Exterior Sealant Passing Grade

Walk the exterior and check the sealant at every window and door. Press on the sealant line gently with a fingernail. If it flexes cleanly, it’s still sound. If it cracks, crumbles, or peels away from the surface, mark that unit for recaulking before the first named storm.

This is the same walkthrough we’ve used since 2009, and it turns most “emergency” callbacks into non-events. If you’d rather not run the checklist yourself, give us a ring – Westlight Windows Fort Lauderdale offers free estimates and we’re happy to walk the exterior with you.

Common Mistakes to Avoid

• Using Windex or ammonia-based cleaners on low-E glass. This is the single most common error we see in Fort Lauderdale homes, and it’s devastating to the coating. Once the metallic film degrades, the glass can’t be repaired – it has to be replaced.
• Pressure-washing window frames and door slabs. The water pressure forces moisture behind the sealant and into the rough opening. In Fort Lauderdale’s humidity, that water doesn’t evaporate. It causes frame rot, mold, and long-term structural compromise.
• Ignoring weep holes because you didn’t know they existed. Most homeowners only learn about weep holes after a water intrusion. Check them monthly during wet season and you’ll never be one of those homeowners.
• Treating a fogged window as a cosmetic issue. Fogging between panes means the seal has failed and the insulating gas has escaped, which means the window’s insulating and possibly impact properties are compromised.
• Lubricating sliders and locks with WD-40. It works for a week, then attracts dust and salt, and the mechanism binds worse than before. Dry silicone lubricant only.
• Painting over weep holes or sealant. Fresh exterior paint looks great, but a brush stroke across a weep hole seals it shut. Check every window after any exterior paint job, and re-clear the holes.
• Running the AC with the house wide open during a “cool” evening. That daily thermal cycle – cold interior, hot evening air, high humidity – is the single most common contributor to seal failure in this market. Close the windows or raise the thermostat, but don’t try to do both at once.

When to Call a Professional

Some Fort Lauderdale window and door problems are beyond the weekend-morning fix. If you see water staining on interior drywall below a window, a door frame that’s visibly separated from the wall, or an impact-rated window with a crack anywhere on the glass surface, don’t attempt a patch. These are structural and safety issues, and a professional assessment is the right call. Same goes for fogged glass, a door that won’t latch after you try adjusting the strike plate, or any sealant failure on a second-story window where the access is tricky.

The Bottom Line

Seasonal window and door care in Fort Lauderdale is not a northern four-season checklist transplanted south. It is a two-season rhythm built around the actual forces your home faces: daily thermal cycling, months of 80%+ humidity, salt air, and storm-driven wind. What you do in the dry season – recaulk, lubricate, clean frames – prevents failure in the wet season. What you do in the wet season – clear weep holes, check sweeps, inspect glass after storms – preserves the home’s conditioned envelope. The dollar-bill test, the no-ammonia rule for low-E glass, and the material-specific cleaning guide are the details that most national guides miss and most local repair calls could have prevented. A treated and maintained window or door in Fort Lauderdale is a 20-year asset; a neglected one is an intermittent expense that compounds.
