Window Replacement Maintenance Checklist for Fort Lauderdale Homeowners

Window Replacement Maintenance Checklist for Fort Lauderdale Homeowners

The most common reason a Fort Lauderdale impact window fails during a hurricane isn’t the glass. It’s a corroded locking mechanism that prevented the sash from compressing the seal fully, a problem a five-minute April inspection would have caught for free. Most window maintenance checklists you’ll find online were written for four-season climates with spring thaws and winter freezes. They’re nearly useless here. This guide is organized around Fort Lauderdale’s actual calendar: the compressed high-stakes window between June and November, and the silent off-season damage that accumulates in hardware during the dry months. You’ll learn exactly what to check each month, which lubricants are safe on aluminum versus vinyl frames, how to test your weep holes in 90 seconds, and the six specific signs that mean it’s time to call a professional rather than reach for a screwdriver.

Quick Answer

A Fort Lauderdale window maintenance routine comes down to monthly weep hole checks, quarterly hardware lubrication with the right product for your frame material, a thorough pre-hurricane season inspection every May, and a post-storm assessment within 48 hours of any named storm. Homeowners can handle about 80% of routine maintenance themselves in under 15 minutes per month. The other 20% requires a professional eye, especially on multi-point locking systems and impact-rated seals where a missed problem becomes a five-figure water damage claim.

The Fort Lauderdale Maintenance Calendar, Month by Month

Fort Lauderdale’s climate doesn’t have four seasons. It has two: a wet season from May through October that delivers roughly 60 inches of rain, and a dry season from November through April where salt air and UV exposure do their slow, quiet damage. Your maintenance schedule should follow that rhythm, not some generic spring-fall split.

Here’s what we recommend, month by month, based on what we’ve seen across hundreds of window service calls in Fort Lauderdale:

1. January: Dry-season caulk and seal audit. Low humidity means caulk pulls away from frames more visibly. Inspect every exterior caulk joint around window frames. Look for gaps, cracks, or areas where caulk has separated from stucco or trim. This is the easiest month to spot problems because the dry air makes gaps more obvious.
2. February: Interior condensation check. Run your hand along the bottom edge of every window interior on a humid morning. Cold-to-the-touch frames or any condensation between glass panes signals a seal failure in double-pane or insulated glass units. In Fort Lauderdale’s climate, seal failures show up most during the dry season when indoor humidity differentials peak.
3. March: Tracks and rollers cleaning. Open every operable window fully and remove debris from the tracks. Fort Lauderdale’s dry season brings fine dust and sand that accumulates in window tracks, especially in coastal neighborhoods like Lauderdale Harbors and Harbor Beach. A damp cloth and a soft brush handle most of it.
4. April: Lock and hardware function test. This is the month that saves windows. Operate every lock, latch, and crank. If anything sticks, binds, or requires excessive force, address it now. You have roughly eight weeks before hurricane season officially starts June 1. Replacement hardware ordered in April arrives in time. Hardware discovered failed in late August is a different story entirely.
5. May: Full pre-hurricane season inspection. Go top to bottom on every window. This includes the weep hole test described below, a full hardware lubrication, and a careful look at impact glass for any chips or cracks larger than a quarter. Fort Lauderdale’s position means we are historically in the cone of concern more than any metro area in Florida, and the time to catch a problem is now.
6. June through November: Monthly post-storm checks. After any named storm passes within 100 miles of Fort Lauderdale, check every window for water intrusion, new cracks, displaced seals, or hardware that no longer engages cleanly. Even tropical storm-force winds can distort frames by fractions of an inch that are invisible to the eye but ruin a seal’s compression.
7. December: Full year review and documentation. Photograph every window from inside and out. Compare against your photos from January. Note any changes on an ongoing basis. If you have a warranty claim, consistent photo documentation is the difference between a covered repair and a denied claim.

This calendar aligns with what Fort Lauderdale homeowners actually experience: a long, punishing wet season that tests seals and weep systems, followed by a dry season that exposes every crack and gap the rain found.

Which Lubricants Are Safe on Aluminum vs. Vinyl Frames

The single biggest mistake we see Fort Lauderdale homeowners make is grabbing a can of WD-40 from the garage and spraying it into window tracks. WD-40 is a water displacer, not a lubricant. It leaves behind a thin film that attracts salt, sand, and dust, which in Fort Lauderdale’s coastal air turns into a grinding paste that wears down hardware faster than no lubricant at all.

Here’s what actually works, specific to the frame material on your windows:

Aluminum Frames

Aluminum impact frames, common in Fort Lauderdale homes built after the 1992 code changes, respond best to dry lubricants. Use a silicone spray with a lightweight carrier that evaporates clean, or a white lithium grease applied sparingly to hinge points and lock mechanism cams. Never use petroleum-based oils on aluminum. They attract salt aerosols that linger in coastal air and accelerate the pitting corrosion that seizes multi-point locks.

Apply lubricant to these specific points on aluminum frames:

• The cam mechanism where the lock engages the striker plate
• Hinge pivot points on casement and awning windows
• The roller assemblies on sliding windows and patio doors
• Friction stay arms on awning windows
• The keeper channel where the locking bolt slides

Vinyl Frames

Vinyl windows, increasingly common in newer Fort Lauderdale construction, need a different approach. Avoid any solvent-based lubricant, which can soften or cloud vinyl. Use a 100% silicone lubricant applied to a cloth first, then wiped onto the contact surfaces. For slide tracks, a dry PTFE spray works well. The goal is a thin film, not a visible coating.

One more note: if your windows are equipped with multi-point locking hardware (the kind where a single handle rotation drives three or more locking bolts into the frame), lubrication is not optional. Multi-point systems rely on perfectly aligned strike plates and smooth cam action. A seized cam in one point means the other points take the load, and in a hurricane, that’s how a window that passed a visual inspection fails under pressure.

How to Test Your Weep Holes in 90 Seconds

Weep holes are the small drain openings at the bottom exterior edge of window frames. They’re designed to channel rainwater that gets past the outer seal down and out of the frame instead of into your wall cavity or onto your interior sill. In Fort Lauderdale’s wet season, a blocked weep hole turns a minor design feature into a major water intrusion problem.

Here is the 90-second test:

1. Locate the weep holes on the bottom exterior edge of the frame. On most windows, they’re small rectangular or circular openings spaced every 12 to 18 inches. On some impact frames, they’re hidden behind a removable cover that flips up.
2. Take a garden hose with a gentle stream, not a pressure nozzle, and direct water at the bottom exterior channel of the frame. Low pressure only. A pressure nozzle can force water past seals that would normally hold.
3. Watch for water exiting the weep holes on the outside. If water pools on the outside track and doesn’t flow out within a few seconds, the weep holes are blocked.
4. For a quick exterior check without water, use a soft brush or compressed air to dislodge accumulated debris. Fort Lauderdale’s dry season leaves fine dust and pollen – and the wet season leaves organic matter – blocking these drains routinely.

Here’s the part most homeowners miss: if the window has interior weep holes too, check those separately. On some impact-rated products from manufacturers like PGT and CGI, the interior track has its own drainage system. Test both. Water exiting the interior weep holes after a rain is normal. Water pooling on your interior sill is not.

Blocked weep holes are the cause behind a surprising number of “window leak” calls we receive in Fort Lauderdale. The window itself is fine. The drainage path is not. Clearing a blocked weep hole takes 30 seconds and costs nothing. Ignoring it can lead to mold, drywall damage, and insulation degradation that runs thousands to remediate.

Hardware Inspection: Locks, Multi-Point Systems, and Hinges

Hardware is where Fort Lauderdale windows die first. The salt air, the humidity cycling between dry season and wet season, the fine sand that blows in from the beach – all of it attacks the moving metal parts long before the glass or the frame shows any sign of trouble. Here’s what to check, and when to act.

Multi-Point Locking Systems

Multi-point locks are standard on higher-end impact windows, and they are the single most important piece of hardware to maintain. When the handle engages correctly, the sash compresses evenly against the weatherstripping around all four sides, creating the air and water seal the window is rated for. When even one point fails to engage, the seal compresses unevenly, and the window loses most of its water resistance.

Test procedure: close the window, operate the handle through its full range, and listen for each locking point engaging. You should hear a distinct click for each point. Run your fingers along the edge of the sash where it meets the frame. Compression should feel even. If the sash lifts slightly at any corner, or if the handle requires more than a moderate push to fully engage, the hardware needs attention.

Hinges on Casement, Awning, and Hopper Windows

Fort Lauderdale’s older homes, especially in neighborhoods like Victoria Park, Rio Vista, and Sailboat Bend, often have casement or awning windows with exposed steel hinges. These hinges take enormous stress because the window’s entire weight rides on them every time it opens. In coastal air, the hinge pins rust, the leaves flex, and eventually the sash sags.

What to check: open the window and support it at the bottom edge. If the sash droops noticeably when the crank is partially open, the hinge mechanism is wearing. If you see rust stains on the hinge leaves or the frame below the hinge, the metal is actively corroding. Replacement hinges are an off-the-shelf item for most hardware manufacturers, and the job is a one-hour service call for a professional.

Strike Plates and Keepers

The strike plate is the metal plate mounted on the frame where the lock bolt enters. On Fort Lauderdale homes that have settled or shifted, the lock bolt no longer aligns with the strike plate, and the homeowner’s solution is often to slam the sash. Each slam bends the strike plate a little more, and eventually the lock stops engaging at all.

If you have to lift, shimmy, or force the window to get the lock to engage, stop doing that. The fix is either a simple strike plate adjustment or, in worse cases, a square-and-shim of the frame. Both are straightforward for a window professional with the right tools. Both become bigger problems the longer they’re ignored.

Seals, Weatherstripping, and Caulk: The Dry-Season Audit

Weatherstripping and caulk are the consumables of window maintenance. They wear out, harden, crack, and lose flexibility on a predictable schedule – about every five to seven years in Fort Lauderdale’s UV-intense climate. The January dry-season audit is the time to check them.

Weatherstripping

Weatherstripping is the compressible material that seals the gap between the sash and the frame when the window is closed. On impact windows, it also plays a critical role in the window’s pressure rating. If the weatherstripping is compressed, torn, or missing, the window will not perform to its design standard in a storm, regardless of how good the glass is.

Check the weatherstripping with the window closed. Run a finger along the seal. It should feel soft and conform to the sash with slight resistance. If it feels hard, brittle, or cracked, it’s done. Look for daylight at the corners with the window closed and locked. Any visible gap larger than 1/16 inch means the seal is no longer doing its job.

Caulk

Caulk is the flexible sealant applied where the window frame meets the exterior wall. In Fort Lauderdale, exterior caulk degrades faster than interior because of direct sun exposure on south-facing and west-facing walls. The January audit is the time to inspect every exterior caulk joint.

What to look for: any hairline crack in the caulk bead, any separation between the caulk and the frame or the stucco, any area where the caulk has pulled away leaving a shadow line. In South Florida’s afternoon thunderstorms, a failed caulk joint channels water directly into the wall cavity. By the time you see it on the interior, the damage has been happening for months.

Recaulking a window is a straightforward job, but the preparation matters. The old caulk must be removed completely, the joint cleaned and dry, and the new caulk tooled properly to allow for thermal movement. For a single window, a homeowner can handle it in about two hours. For a whole-house recaulk, that’s a job most Fort Lauderdale homeowners hire out.

This is also a good moment to note the product depth that matters here. Impact-rated lines like PGT and CGI, plus energy-focused brands like ViewLux and ES Windows, all have specific glide and seal materials engineered for coastal environments. When you do need weatherstripping or seal replacement, matching the right replacement material to the specific window brand matters more than most people think. A universal weatherstrip from a big-box store will almost never have the exact compression profile of the original, which means the window’s air and water resistance takes a permanent hit from the first day of the replacement.

Six Signs You Need a Professional Inspection, Not DIY

There’s a line between maintenance and repair. Cross it with a screwdriver in your hand, and you can convert a $200 hardware replacement into a $1,800 sash replacement or a voided warranty. Here are the six signs that mean put the tools down and call someone who does this daily.

1. Visible gaps in weatherstripping larger than 1/16 inch. If you can slide a dime through the gap between the sash and the frame when the window is closed and locked, the seal has failed beyond what a homeowner can correct with off-the-shelf materials. The window needs professional weatherstripping replacement with the correct profile.
2. Hardware that requires more than 15 pounds of force to engage. A properly maintained window lock should operate with one or two fingers. If you have to lean on the handle or use both hands, something is out of alignment. The fix is alignment correction, not more force, and the root cause could be frame racking from settling.
3. Condensation between the glass panes. Double-pane and insulated glass units are sealed at the factory. When moisture appears between the panes, the seal has failed, and the glass unit needs replacement. There is no field repair. In Fort Lauderdale’s humidity, a failed seal also means you’re paying to cool air that’s now leaking through the window’s dead air space.
4. Water staining on the interior sill or wall below a window. Water inside means the drainage system – weep holes, internal channels, or exterior caulk – has failed somewhere. By the time the stain is visible, water has been moving through the wall cavity long enough to leave a mark. A professional can trace the actual entry point, which is often not where the stain appears.
5. Cracks or chips in impact-rated glass larger than a quarter. Impact glass is engineered to survive a specific impact. Once it sustains visible damage larger than a quarter, the structural integrity of the entire pane is compromised. This is not a cosmetic issue. In hurricane season, a compromised pane can fail catastrophically.
6. A window that opens or closes on its own. If gravity moves the sash, the balance system or hinges have failed. This means the window can’t be relied on to stay closed under wind load, and the constant movement is grinding away at whatever hardware is left. It’s the canary in the coal mine for a bigger issue.

Each of these is a call to a professional rather than a trip to the hardware store. In our experience doing window repair in Fort Lauderdale, the jobs where a homeowner tried to fix it themselves first are consistently more expensive than they would have been as a simple professional repair.

The Post-Hurricane Checklist: Document, Assess, Repair

After any storm in Fort Lauderdale, your windows need a structured assessment within 48 hours. Here’s the protocol, in order:

First, document everything before you clean anything. Photograph every window from inside and outside, even the ones that look fine. Use your phone’s timestamp. Get close-ups of any visible damage, cracks, chips, or displaced seals. These photos are the foundation of any insurance claim, and having “before” documentation from your December photo session makes the claim stronger.

Second, assess whether the damage is cosmetic or structural. Here’s the distinction that matters:

• Cosmetic issues you can document and handle later: Surface scratches on glass, scuff marks on frames, minor paint chipping, dirt and debris in tracks, small dents that don’t affect the window’s operation, stretched or torn window screens. None of these threaten the building envelope. Document them, note them for future repair, and move on.
• Structural issues that require a licensed contractor before re-glazing: Broken or displaced glass that allowed water or wind into the building, frames that shifted or pulled away from the wall, hardware that no longer engages, any window that was bowed, racked, or visibly moved during the storm, and any window that shows water staining after the storm. These cannot wait.

Third, do not attempt to re-glaze or “fix” a structural issue yourself. Impact windows carry specific code requirements in Fort Lauderdale, and a homeowner repair that doesn’t meet Florida Building Code will be flagged at resale and may void remaining warranty. If you need a window replacement in Fort Lauderdale after a storm, go through a licensed contractor who pulls the permit and passes the inspection.

For structural damage that needs replacement, the Homeowner should be clear about one thing: if water got into the wall cavity around the window, the job is bigger than the window itself. The surrounding wall needs to be opened, the insulation checked for saturation, and the opening re-flashed properly. A contractor who only swaps the window without addressing the wall is leaving you with a mold problem that will surface months later.

Common Mistakes to Avoid

• Using WD-40 on window hardware. WD-40 is a solvent and water displacer, not a window lubricant. In Fort Lauderdale’s coastal air, the residue it leaves behind attracts salt and sand, which turns into an abrasive paste that accelerates the very corrosion you’re trying to prevent.
• Pressure-washing window exteriors during the wet season. A pressure washer forces water past seals that are engineered for rain, not for a 2,000 PSI direct stream. We’ve seen homeowners create interior water damage with a “cleaning” that was more destructive than any storm.
• Ignoring blocked weep holes because “the window looks fine.” Weep holes exist to drain water that gets past the outer seal. A blocked weep hole doesn’t change how the window looks from inside until the water has already caused damage behind the wall. Test your weep holes monthly during the wet season.
• Skipping the May pre-hurricane hardware check. Every year, the calls start in August with a failed lock that would have been a $15 part and a 30-minute visit in April. In August, during a storm watch, that same repair costs more and may not be completed before the storm arrives.
• Replacing weatherstripping with universal material from a big-box store. Impact windows from different manufacturers use different seal compression profiles. A universal weatherstrip doesn’t match, which means the window’s air and water resistance rating drops immediately. The seal looks fine and performs poorly.
• Re-caulking over old caulk. New caulk needs a clean, dry surface to bond. Applying it over old, failed caulk creates a cosmetic fix that channels water behind both layers. Remove the old bead completely before applying new material.
• Documenting damage only after cleaning up. Insurance adjusters need to see the damage as it occurred. Clean the glass, and you’ve erased the evidence. Photograph everything in its storm-damaged state first.

When to Call a Professional

If you’ve identified any of the six signs above, or if a post-storm assessment shows structural damage, call a professional. A professional window inspection in Fort Lauderdale costs between $75 and $150 when billed as a standalone visit, and many companies – including ours – waive that fee when the visit results in a repair.

The Bottom Line

A Fort Lauderdale window maintenance routine doesn’t require much time. Fifteen minutes per month, a disciplined May pre-hurricane inspection, and a structured post-storm protocol will save you money on repairs and energy, protect your home during the months that matter most, and preserve whatever warranty you have. The tools are simple: the right lubricant for your frame material, a garden hose for weep holes on a low setting, a soft-bristle brush, and a phone camera for documentation. What’s not simple is recovering from the damage caused by the inspection you skipped. The window that fails in a hurricane was usually failing quietly for months before the storm named it.
