Impact Windows Maintenance Checklist for Fort Lauderdale Homeowners

Impact Windows Maintenance Checklist for Fort Lauderdale Homeowners

Here’s a number that surprises most Fort Lauderdale homeowners: a PGT or CGI impact window that costs $1,800 to install can lose its entire manufacturer warranty over a blocked weep hole the size of a fingernail. Not a cracked frame. Not a shattered laminate. A clogged drainage channel that nobody noticed for two rainy seasons. Our Impact Windows services are marketed as the ultimate set-it-and-forget-it upgrade, and compared to standard single-pane glass, they are remarkably low-maintenance. But Fort Lauderdale’s salt-humid air, relentless UV exposure, and six-month rainy season create a very specific set of failure points that generic maintenance advice never covers. This guide is built around what actually degrades first in coastal Broward County, not what looks good in a national blog. By the end, you’ll know exactly what to check, how often, what you can safely do yourself, and when to pick up the phone.

Quick Answer

An impact window maintenance checklist for Fort Lauderdale should include four core tasks most months: clearing weep holes of salt and debris, inspecting the silicone glazing bead for UV shrinkage, lubricating and cleaning tracks and hardware, and checking the sealant bead around the frame perimeter. Coastal properties within two miles of the Atlantic need weep hole clearing every 60 to 90 days during wet season, while inland neighborhoods can typically stretch that to every 4 to 6 months. Annual professional inspections are the single most effective way to catch warranty-voiding problems before they become expensive.

Why Weep Holes Are the First Thing to Fail in Fort Lauderdale

Every impact window has small drainage channels along the bottom track or frame called weep holes. They are engineered to let water that gets past the exterior seal drain outward instead of pooling inside the frame. In most of the country, weep holes go years without attention. In Fort Lauderdale, that is not the case.

The salt air does two things at once. It leaves a fine crystalline residue that accumulates inside the weep channel, and it mixes with the organic matter that blows in from landscaping, sea grapes, and palm debris to form a paste that hardens in place. We have seen weep holes in Victoria Park and Rio Vista completely sealed within a single wet season, and that is on homes more than a mile from the ocean. In Harbor Beach, Lauderdale-by-the-Sea, and other east-of-US1 neighborhoods, the salt loading is noticeably heavier and the clogging happens faster.

Why this matters financially: most manufacturer warranties, including those from PGT and CGI, include language about proper drainage maintenance. A blocked weep hole that leads to water intrusion, frame corrosion, or interior water damage can give the manufacturer grounds to deny a claim. The good news is that clearing weep holes is a five-minute job you can do yourself.

How to Clear Weep Holes Safely

1. Locate the weep holes along the bottom exterior edge of the frame. Most impact windows have two to four per sash.
2. Use a thin, non-metallic tool like a straightened plastic clothes hanger, a zip tie, or a dedicated weep hole brush. Metal tools can scratch the frame and create a new corrosion point.
3. Gently insert the tool and push through to the interior side. You are clearing a channel, not digging.
4. Flush the channel with a cup of clean water and watch for it to drain out the exterior. If water pools, the channel is still blocked.
5. Repeat the flush after a heavy rain if you live within two miles of the coast.

Frequency: for homes east of US1 or within two miles of the ocean, clear weep holes every 60 to 90 days from May through November. Inland Fort Lauderdale neighborhoods like Plantation, Davie, and western Sunrise can extend the interval to every 4 to 6 months. If you are unsure whether your home counts as coastal for maintenance purposes, the salt haze you find on your car windshield in the morning is a reliable indicator.

This is the single most overlooked task on any impact window maintenance checklist, and in our experience, it accounts for the majority of warranty-voiding situations we correct in Fort Lauderdale. For more context on how these windows are built and what makes a quality installation, see our guide to Impact Windows in Fort Lauderdale.

The Silicone Glazing Bead: The Failure Point Nobody Mentions

Between the glass and the frame of your impact window sits a silicone glazing bead. It seals the glass unit into the frame and prevents water from wicking into the gap. Silicone is flexible, which is good, but Fort Lauderdale’s UV index, which runs high or extreme for much of the year, breaks down silicone faster than almost any other environment in the continental United States.

The failure pattern looks like this: the silicone starts to shrink, pulling away from the glass or frame in thin gaps. Then hairline cracks appear along the edge. Then a small section separates entirely, and water finds the opening. The window still looks fine from ten feet away. The damage happens silently inside the frame, where water sits against the laminate edge and begins to degrade the bond between the glass and the interlayer.

This is the precise failure point that precedes water intrusion, and it is almost never mentioned in impact window sales literature. Most manufacturers expect builders and homeowners to replace glazing beads on a schedule, but that information rarely makes it into the hands of the person who owns the house.

How to Inspect the Glazing Bead

1. Stand inside the house and look at the perimeter of each glass panel where it meets the frame.
2. Run a fingertip along the bead. It should feel continuous and slightly tacky, not hard and crusty.
3. Look for any spot where the silicone has pulled back from the glass, exposing a dark gap.
4. Check the corners first. UV-driven shrinkage always starts at the corners because that is where the material is under the most mechanical stress.
5. Do this inspection on the south and west facing windows first, as they absorb the most direct sun in Fort Lauderdale’s latitude.

If the bead is showing early signs of shrinkage but has not separated, a professional can remove and reapply the bead without replacing the window. If the separation is allowed to progress, the glass unit itself may lose its seal and require replacement. A ten-minute inspection twice a year prevents most of this.

Frame-Specific Care: Aluminum, Vinyl, and Fiberglass in South Florida Humidity

Impact windows in Fort Lauderdale come in three primary frame materials, and each one responds differently to sustained heat and humidity. The maintenance routine you follow depends on what your house actually has.

Aluminum Frames

Aluminum is the most common impact window frame in coastal South Florida because it is strong and resistant to warping. But raw aluminum oxidizes in salt air. Modern impact windows use anodized or powder-coated finishes that protect the metal, but any scratch that cuts through the finish exposes the raw material underneath. In Fort Lauderdale’s humidity, that exposed aluminum begins to pit and corrode within months.

• Routine: Wash frames with mild soap and water twice a year. Check for scratches and nicks, especially after storms or lawn equipment contact.
• Salt removal: Rinse frames after coastal storms. Salt sitting on anodized aluminum for weeks will accelerate finish breakdown even without visible damage.
• Hardware: Clean and lubricate locking mechanisms with a dry silicone spray. Do not use WD-40 or petroleum-based lubricants, which attract grime and salt.

Vinyl Frames

Vinyl is popular for energy efficiency and price. It does not corrode the way aluminum does, but it expands and contracts with temperature swings, and Fort Lauderdale’s summer sun pushes vinyl frames through a wider thermal cycle than most climates. Over time, that movement can loosen the frame’s seal against the rough opening, creating small gaps where humid air and rainwater find their way in.

• Routine: Inspect the perimeter caulk line twice a year for separation or cracking.
• Watch for: Warping or discoloration on south-facing windows. Vinyl that has been baked by sustained UV will become brittle and may crack.
• Cleaning: Use a non-abrasive cleaner. Harsh solvents can break down vinyl’s UV stabilizers and shorten its life.

Fiberglass Frames

Fiberglass is the least common of the three in Fort Lauderdale, but it is gaining ground because it moves less than vinyl and does not corrode like aluminum. Fiberglass is the most forgiving frame material in a salt-humid environment. Its primary weakness is the finish, which can chalk over time under UV exposure.

• Routine: Wash twice a year. Apply a UV-protectant sealant made for fiberglass annually if the finish looks chalky.
• Watch for: Finish degradation that exposes the glass fibers underneath. Once fiberglass strands are visible, the frame needs professional refinishing to prevent water absorption.

Regardless of frame material, the perimeter sealant between the frame and the house is the line of defense that most directly affects the wall cavity. We replace more rotted wall framing behind windows in Fort Lauderdale than most homeowners would believe, and the culprit is almost always a failed perimeter bead that was never re-caulked after installation. For a deeper look at how frame selection and installation quality affect performance, see our guide to Window Installation in Fort Lauderdale.

Pre-Hurricane-Season Checklist: The Warranty-Protection Run

Every June, before the peak of hurricane season, there is one check that can mean the difference between a covered claim and a denied one. It takes under an hour, costs nothing, and requires no special tools.

Manufacturers and insurers both look for evidence that the homeowner maintained the windows in a condition that allowed them to perform as designed. If a window fails during a storm and the investigation finds that weep holes were blocked, hardware was corroded, or seals were already compromised and unattended, the claim can be denied on a maintenance exclusion. We have helped homeowners in Fort Lauderdale navigate this exact situation, and it is avoidable.

The June Checklist

1. Clear every weep hole on every window and sliding glass door. Flush each one with water to confirm drainage.
2. Inspect every glazing bead on all windows. Pay special attention to upper-floor windows that are hard to see from ground level. Use binoculars if needed, or hire a professional for a ladder inspection.
3. Test every locking mechanism. Open and close each window fully. A window that sticks during calm weather may not seat properly under wind load.
4. Photograph the condition of every window. Date-stamped photos are your best evidence if a claim dispute arises later.
5. Check the frame-to-house sealant around every opening, including transoms and fixed picture windows.
6. Look for any crack, chip, or scratch in the glass. Impact windows can shrug off small damage in normal conditions, but under positive and negative wind pressure, a compromised point becomes a failure point.

This is also the right time to schedule a professional inspection if you have not had one in the past two years-see our Seasonal Windows & Doors Care for Fort Lauderdale: Year-Round Homeowner’s Guide for timing. A trained eye catches things a homeowner misses, and the documentation from a professional inspection strengthens your position with both the manufacturer and your insurer. Ed Winslow has been inspecting impact windows in Fort Lauderdale since 2011, and we have built our reputation on honest inspections that do not invent problems to sell repairs.

The Monthly and Seasonal Maintenance Schedule

Impact window maintenance in Fort Lauderdale is not a monthly chore for most windows. What matters more than frequency is rhythm: a light routine you keep without thinking, and two deeper seasonal passes each year.

Monthly: The Two-Minute Walkaround

• Walk the exterior of the house and glance at the weep holes on ground-floor windows. Clear any that look obstructed.
• Open one window per room and close it again. This catches hardware that is starting to bind before it seizes completely.
• After heavy rain, check the interior windowsills for any sign of water. A damp sill after a storm is the earliest indicator of a seal problem.

Quarterly: The Cleaning Run

• Wash window tracks with mild soap and water. Remove all sand and grit, which acts as an abrasive on rollers and weatherstripping.
• Lubricate friction hinges, rollers, and locking points with dry silicone spray.
• Inspect weatherstripping for compression set. In Fort Lauderdale’s heat, compressed weatherstripping has a shorter life than in temperate climates.
• Check the exterior frame-to-house caulk bead for any cracks or gaps that opened since the last inspection.

Biannual: The Deep Inspection

• Complete weep hole clearing and flushing on all windows.
• Full glazing bead inspection. This is the time to catch UV shrinkage before it opens a gap.
• Frame finish inspection, checking for scratches, chips, pitting, or chalking based on your frame material.
• Hardware torque check on all hinges, keepers, and locking points.
• Photograph everything. Documentation builds the maintenance history that protects your warranty.

For homeowners who want a professional eye on their windows without committing to anything, we offer free second opinions on written estimates from any other company. If another contractor has told you something about your impact windows that does not sound right, bring it to us and we will tell you the truth. That is part of how we have operated in Fort Lauderdale since 2011.

When Maintenance Crosses into Repair Territory

Routine maintenance stops being routine the moment you find one of these conditions. Each one is a sign that the window has moved past prevention and into active degradation. Ignoring them costs more later, and in some cases, continuing to operate the window can cause secondary damage that the manufacturer will not cover.

Signs That a Professional Needs to Look

• Water intrusion that recurs after weep holes are cleared. This means the water is getting in somewhere other than the designed drainage path, which points to a seal failure.
• Fogging or condensation between the glass panes. The insulated glass unit seal has failed. The insulating gas is gone and the window’s energy performance is compromised. This requires glass replacement, not cleaning.
• Visible mold or mildew growth inside the track or around the frame. Chronic moisture inside the frame indicates a drainage or seal problem that has been active for months.
• A sash that binds, sticks, or falls when opened. Hardware has failed or the frame has shifted. Forcing it open can break the lock or strip the hinge.
• Cracks in the glass, even hairline ones. Impact glass is laminated, so small cracks do not shatter the window, but they reduce the window’s structural performance and will spread.
• Gaps between the glazing bead and the glass that have fully opened. This is an active leak, not an early warning sign.

A legitimate contractor inspection should include: a complete weep hole audit with water flush testing, a glazing bead inspection with a written condition report, a hardware function test on every operable window, a sealant assessment around every frame, and photographic documentation of everything found. For what this should cost, read our Windows & Doors Cost Breakdown: The Fort Lauderdale Homeowner’s Reference for 2026. What it should not include is a sales pitch disguised as an inspection. If the inspector spends more time quoting replacement prices than showing you what is wrong, get a second opinion.

Common Mistakes to Avoid

• Using a pressure washer on impact windows. High-pressure water forces its way past the exterior seals and into the frame, causing exactly the water damage the weep holes are designed to drain. Fort Lauderdale’s soft limestone water also leaves mineral deposits that accumulate in weep channels. Use a garden hose and a soft brush instead.
• Painting over weep holes. This happens more often than most people realize, particularly after a house repaint. A painter who does not know impact windows will paint right over the drainage channels. Blocked weep holes with a fresh coat of paint are a warranty problem waiting to happen. Always check weep holes after any exterior painting.
• Ignoring the interior side of the frame. Many homeowners only maintain the exterior, but the interior track is where roller mechanisms, locking points, and weatherstripping live. A window that operates well from the outside can still have failing hardware on the inside.
• Using the wrong lubricant. Petroleum-based sprays like WD-40 degrade rubber weatherstripping and attract salt and sand in Fort Lauderdale’s coastal air. Use dry silicone or PTFE-based lubricants only.
• Assuming a warranty covers everything automatically. Manufacturer warranties are contracts with conditions. Maintenance documentation, including photos and receipts, is your evidence that you upheld your end. In our experience helping Fort Lauderdale homeowners with warranty claims, documented maintenance is the single strongest factor in getting a claim approved.
• Waiting until after hurricane season to inspect. By September, the damage is done. The pre-season June check is what protects both the window and the claim.
• Treating all windows the same. The east-facing windows on a Lauderdale Isles canal-front home face different conditions than the north-facing windows in a Weston interior lot. Salt exposure, sun angle, and drainage patterns vary by elevation and proximity to water. Tailor your routine to what your specific house actually experiences.

When to Call a Professional

You can handle most routine impact window maintenance with a soft brush, a hose, and thirty minutes every few months. But some conditions demand a trained eye and a professional touch. If you find recurring water intrusion after clearing weep holes, fogging between panes, a sash that will not stay open, glass cracks of any size, or a glazing bead that has separated from the frame, stop the DIY routine and get a professional assessment. Continuing to operate a window with compromised hardware can turn a $200 repair into a $1,800 replacement.
