When your impact windows are brand new, everything looks and feels perfect. Then the first real South Florida storm hits, wind shifts, rain goes sideways, and the house pressure changes. That is when homeowners in Palm Beach County and Broward County get their first true performance report.
This guide is your post-installation reality check: what to inspect after the first big storm, what is normal, what is not, and when to call for service. It is written for real homes in West Palm Beach, Wellington, Boynton Beach, Delray Beach, Boca Raton, Jupiter, Palm Beach Gardens, Fort Lauderdale, Hollywood, Pembroke Pines, Miramar, Coral Springs, and the coastal neighborhoods where salt, wind-driven rain, and negative pressure show up fast.
If you need professional help, Window Guys of Florida is licensed and insured, with 25+ years of experience, and we install and service top brands like PGT, CGI, ES Windows, Andersen, and more. You can schedule a free consultation here: Contact/Free Quote.
Why the first big storm matters (even with brand-new impact windows)
Impact windows are tested to strict standards, but the real world is messy. A storm combines gusts, sustained pressure changes, wind-driven rain, debris, and long periods of saturation. Even a correct installation can reveal small issues after the first major weather event, including:
- Sealants that pull back as materials settle
- Minor fastener movement after repeated gust cycles
- Drainage paths that clog with construction dust, sand, or landscaping debris
- Hardware that needs micro-adjustment after the frame experiences load
The data point homeowners miss: wind-driven rain is the real leak test
The National Hurricane Center notes that freshwater flooding and rain impacts are major drivers of storm damage, and South Florida storms often produce intense rain bands long before and after the strongest winds. A window that “never leaks in normal rain” can still show water entry during wind-driven rain.
If your home is near the Intracoastal, canals, Lake Okeechobee-connected waterways, or barrier island exposures, you have extra reasons to inspect carefully. Related reading:

When to inspect: the best timing after a storm
Aim for a two-pass inspection.
First pass: within 24 to 48 hours
This catches active moisture, fresh staining, and drainage problems before everything dries.
Second pass: 7 to 14 days later
This is when you may notice caulk shrinkage, hardware settling, or intermittent symptoms that only show up after repeated opening and closing.
If you are a condo owner, you may also be dealing with association requirements and approvals for any exterior changes or repairs. These can affect how quickly you can address a problem, so document early.

Your post-storm inspection checklist (step-by-step)
Below is a practical checklist designed for how to check impact windows after hurricane conditions in Palm Beach and Broward.
1) Start inside: look for water intrusion patterns (not just “a wet spot”)
Target keyword focus: impact window water intrusion signs
Walk every room and check each opening from top to bottom. Use a bright flashlight and your phone camera.
What to look for
- Drywall bubbling or soft spots at the top corners of window returns
- Brown or yellow staining that appears in arcs or vertical streaks
- Baseboard swelling near the window wall
- Floor cupping (engineered wood and laminate show this quickly)
- Musty smell localized to one opening
- Condensation between panes (for IGU units), which can indicate seal failure
Common “false alarms” to rule out
- Condensation on the room-side glass due to AC set low after a power outage. This is common when indoor humidity spikes.
- Water from above such as roof leaks that run down a wall and present near a window.
If the storm brought “rain bomb” conditions, use this guide to match symptoms to causes:
Quick homeowner test
- Wipe the area dry.
- Place a paper towel along the interior sill and bottom corners.
- Check again after the next heavy rain or after running a hose test (only if safe and controlled).
2) Check the interior sill and weep behavior (how the window manages water)
Impact windows are designed to manage some water in the track area and direct it out through weeps. After a storm:
- Look for standing water that does not drain
- Look for debris in weep slots (sand is common in Boca Raton, Deerfield Beach, and coastal Fort Lauderdale)
- Look for water that appears behind trim rather than in the track
Standing water in the track can be normal briefly during extreme wind-driven rain, but it should drain. Persistent pooling can point to blocked weeps, improper slope, or installation details that need service.
3) Inspect caulk and sealant lines outside (from the ground if possible)
Target keyword focus: impact window caulk failure
Do a perimeter scan. You are looking for continuity and adhesion.
Signs of caulk failure
- Hairline separation where sealant meets frame or stucco
- Small gaps at the top corners or along the sill edge
- Sealant that looks torn, chalky, or brittle
- Sealant that pulled away in one continuous strip
Why this shows up after the first big storm
New installations can experience initial movement as fasteners, shims, and framing settle. In South Florida, thermal expansion also cycles hard, especially on west-facing elevations.
Important: do not “touch up” with random big-box caulk without confirming compatibility. Some sealants do not bond well to certain finishes or can trap moisture. A professional evaluation prevents repeated failure.
4) Look for frame movement and cracked finishes around the opening
Storm loads can reveal subtle movement. Check:
- Hairline cracks radiating from the corners of the opening
- New separation between trim and wall
- Exterior stucco cracks that align with window corners
- Window that suddenly looks slightly out of square (gaps around sash change)
This does not automatically mean the window is unsafe. It can mean finishing materials moved or that adjustments are needed. If you see multiple openings with similar symptoms, it is worth a professional review.
For context on what tends to go wrong when installation details are off:
5) Operate every window: smooth travel, tight locks, and even contact
Target keyword focus: hurricane window maintenance south florida
After a storm, open, close, and lock every unit. Do not assume “it looks fine” means “it is fine.”
What to feel for
- New rubbing or binding when sliding up or sideways
- Lock that needs extra force to engage
- Tilt latches that feel uneven
- A sash that does not sit evenly when closed
Why it matters
Hardware that is slightly out of adjustment can:
- Reduce weather resistance during the next storm
- Accelerate wear on rollers, balances, or lock keepers
- Create small leak paths under pressure
If you live close to salt air zones, pay extra attention because corrosion can begin early if coatings and cleaning routines are not right.

6) Sliding glass doors and impact doors: inspect tracks, rollers, and water paths
Do not skip doors. Many post-storm service calls involve sliders.
- Check the track for grit and sand (rollers hate this)
- Look for water pooling at the interior edge
- Confirm the interlock closes tightly and evenly
- Confirm multipoint locks engage smoothly
If you have large openings facing prevailing wind (common in waterfront properties in Palm Beach Gardens, Jupiter, and Lauderdale-by-the-Sea), doors take a beating.

7) Screen enclosures, Florida rooms, and corner-lot exposures: inspect pressure-related weak points
Corner-lot homes in places like Wellington, Parkland, and Coral Springs often get hit from multiple angles as gusts wrap around the structure.
- Look for water entry at side legs and lower corners
- Inspect corners where wind creates suction (negative pressure)
- Check any mulled units (multiple windows joined together)

8) Confirm glass condition: chips, edge damage, and interlayer performance
Impact glass can take a hit and still look “mostly fine.” After a storm:
- Inspect edges and corners for chips
- Look for new cracks (even short ones)
- Look for “milky” haze or delamination signs along edges (rare, but important)
If your neighborhood saw debris impacts, it helps to understand what the glass was designed to withstand:
9) Review drainage and grading around the home (water can look like a window leak)
In many Palm Beach County neighborhoods with flat lots and heavy summer downpours, water can pool against walls. If exterior water rises against stucco and penetrates at weak points, it may present as a “window leak.”
Check:
- Mulch piled too high against the wall under windows
- Clogged gutters dumping water near openings
- Soil grade sloping toward the house
This is especially relevant after king tides, canal swell, or localized flooding.
10) Document everything like an insurance adjuster would
If you suspect a defect or storm-related damage, documentation matters.
What to capture
- Wide shot of the wall and window location
- Close-ups of stains, gaps, cracks, or wet materials
- A short video showing water path or active dripping
- Date and time, plus storm name if applicable
If you are pursuing insurance credits or need paperwork, keep your window documentation organized.
Palm Beach vs Broward: why post-storm checks can differ by neighborhood
Not all exposures are equal. Coastal zones and wind-borne debris regions (WBDR) can mean higher design pressure requirements and different inspection practices.

If you are unsure what was permitted or inspected for your project, this helps you decode the paperwork:
What is normal after a storm vs what needs service now
Usually normal
- Minor water in the outer track that drains
- Light dirt streaking on frames from wind-blown debris
- Temporary interior condensation when humidity spiked during an outage
Service soon (schedule within days)
- Repeated damp drywall at corners
- Caulk separation along a continuous edge
- Sticky locks or windows that suddenly bind
- Water that appears behind trim or below sill onto flooring
Service now (urgent)
- Cracked glass or chipped edges that spread
- Door that will not lock or seal
- Visible frame separation, fastener issues, or large new cracks in surrounding wall finishes
If you need Palm Beach County impact windows service or Broward County impact windows service, Window Guys of Florida can inspect and recommend the right fix.
Homeowner maintenance basics after the storm (what you can do safely)
This is not about heavy repairs, it is about keeping performance high.
Clean tracks and weeps
- Vacuum loose debris
- Wipe tracks with mild soap and water
- Confirm weep holes are not packed with sand
Rinse salt film in coastal areas
If you are in Jupiter, Juno Beach, Palm Beach Shores, Singer Island, Hillsboro Beach, or other salt-air corridors, rinsing frames and hardware reduces corrosion risk.
Lubricate hardware only if manufacturer-approved
Use the correct products for your hardware type. If you are unsure, ask during a service visit.
For a seasonal approach, keep this handy:
When the issue is not the window: common look-alikes
Homeowners often blame the new impact windows when the real culprit is elsewhere.
Roof or soffit leaks that track down to a window
Water can travel along framing and appear at window corners.
Stucco cracking unrelated to the frame
Settlement or older stucco can crack during pressure cycling.
AC humidity and negative pressure behavior
After storms, many homes run on generator power or change HVAC patterns. That can change indoor pressure and condensation behavior.
Also avoid last-minute “storm hacks” that create new leak points.
Planning ahead for the next storm: performance, comfort, and noise
After your first storm, you may realize you want upgrades like better acoustic performance near flight paths or rail corridors.
Or you might re-evaluate shutters vs impact windows for convenience and long-term ownership.
If you are considering additional openings, do not forget upstairs exposures.

FAQ: Post-storm impact window inspection in Palm Beach and Broward
1) How soon should I do an impact window post storm inspection?
Within 24 to 48 hours for moisture and active leak signs, then again 7 to 14 days later to catch settling, hardware shifts, or delayed caulk issues. If you want a professional assessment, schedule through Contact/Free Quote.
2) What are the most common impact window water intrusion signs after a hurricane?
Look for damp drywall at top corners, staining around the window return, swollen baseboards, wet flooring near the sill, and water appearing behind interior trim. For wind-driven rain scenarios, see Stop Rain Bomb Leaks Around Impact Windows in FL.
3) How do I tell if I have impact window caulk failure?
Check for gaps where sealant meets the frame or stucco, pulled-back beads at corners, brittle or cracking sealant, and separations that run continuously along one edge. Avoid applying random caulk until the correct product and detail is confirmed, a mismatched sealant can fail again.
