Should I Replace 20-Year-Old Windows?

October 30, 2026 By Webmaster

Twenty years is a reason to assess your windows, not an automatic replacement deadline. Window replacement becomes more compelling when aging units have persistent drafts, failed insulated glass, deteriorating frames, recurring water entry, or operating problems. Sound windows with isolated hardware or weatherstripping issues may still be repairable.

During November and December, focus on symptoms affecting comfort and weather protection. A cold room alone does not prove the windows need replacing. Air leakage, glazing performance, insulation, indoor humidity, and heating-system operation can all influence how comfortable the space feels.

What Signs Suggest Window Replacement Is Worthwhile?

Inspect each window individually rather than assuming every unit has aged identically. Look for:

Persistent drafts around closed sashes or frames.
Fog between panes that cannot be wiped away.
Soft, cracked, swollen, or deteriorated framing.
Repeated water staining around interior finishes.
Sashes that stick, sag, or no longer lock securely.
Cracked glass or damaged operating components.

Between-pane fogging usually indicates a failed insulated glass seal. It differs from moisture collecting on the room-facing surface, which can relate to indoor humidity and cold glass. Identifying the moisture location helps prevent an unnecessary replacement recommendation.

When Is Repair Better Than Replacement?

Repair can make sense when the problem is limited and the surrounding assembly remains sound. Worn weatherstripping, damaged hardware, or an isolated glazing failure may not require removing the entire frame.

Ask an installer to separate the diagnosis from the proposed solution:

Where is air entering?
Is the frame damaged?
Is only the insulated glass affected?
Are compatible replacement components available?

Replacing glass may address failed glazing but will not repair a deteriorated frame. Likewise, fresh weatherstripping cannot restore an insulated unit with moisture trapped between its panes.

What Should New Windows Improve?

A replacement should solve documented problems rather than simply provide a newer appearance. Depending on the selected product and installation, priorities might include:

Better resistance to air leakage.
Improved glazing performance.
Reliable opening, closing, and locking.
Ventilation suited to the room.
A durable connection between the window and wall.
A style that complements the building.

Compare product specifications, warranty terms, and installation scope. Do not assume every replacement offers identical thermal performance or that energy savings will quickly repay the project cost. The right choice balances condition, comfort, function, and budget.

Can Windows Be Replaced During Cold Weather?

Cold-weather replacement requires planning around suitable installation conditions, product instructions, and protection of the occupied space. Ask how the installer will manage temporary exposure, sealant requirements, interior protection, and unexpected damage around the opening.

Confirm who handles trim, disposal, wall repairs, and finishing. These details influence both the quotation and the completed result.

If glass is broken or water is entering, request prompt professional advice rather than waiting for warmer weather. Urgent weather protection and a scheduled upgrade require different responses.

What Should You Confirm Before Booking?

Request a written assessment covering the cause of failure, recommended products, installation method, warranty, and exclusions. Compare equivalent scopes rather than headline prices.

Keep a room-by-room list of concerns. If only several windows perform poorly, ask whether phased replacement makes sense. Replacing everything together may be convenient, but the decision should reflect actual condition.

Why Is My Skylight Foggy Between the Glass Panes?

October 29, 2026 By Webmaster

Fog trapped between skylight panes usually means the insulated glass unit’s edge seal has failed, allowing moisture into the space between the glass. Unlike condensation on an accessible surface, this moisture cannot be wiped away. Replacing the affected glass unit, or the skylight when necessary, is generally the lasting solution.

November and December often make the problem more noticeable. Cold outdoor temperatures encourage moisture inside compromised glazing to condense. The skylight may appear clear during certain hours and cloudy during others. Temporary clearing, however, does not necessarily mean the seal has recovered.

Is It Failed Skylight Seals or Surface Condensation?

Before arranging repairs, identify where the moisture appears. These three situations require different responses:

Interior condensation: Moisture forms on the glass facing the room and can usually be wiped away when safely accessible.
Exterior condensation: Moisture develops outside the skylight under certain weather conditions.
Between-pane fogging: Haze, droplets, or streaks remain inside the sealed glass assembly and cannot be reached by cleaning.

Only check the interior glass if you can reach it safely. Do not climb onto the roof. Photograph the fogging and note whether it follows cold nights, bathing, cooking, or rainfall.

Why Do Skylight Seals Fail?

Insulated glazing depends on a sealed perimeter to keep moisture out. Repeated temperature changes, installation stresses, weather exposure, and material deterioration can eventually compromise that perimeter.

When moisture enters, the unit’s moisture-absorbing material can become overwhelmed. Condensation then develops between the panes. In gas-filled units, seal failure may also allow insulating gas to escape, reducing the glazing’s original thermal performance.

This differs from damaged flashing. Flashing directs roof water around the skylight opening. A skylight can have foggy insulated glass without leaking rainwater. Similarly, roof-related leakage can occur while the glass remains clear.

Can Cleaning or Caulking Remove the Fog?

Cleaning accessible surfaces will not remove moisture trapped inside insulated glazing. Adding caulk around the outside does not reconstruct the factory-made glass seal or restore lost insulating gas.

Defogging treatments may improve appearance in some situations, but cosmetic clearing should not be confused with restoring the original glazing system. Before approving treatment, ask:

Does it restore the sealed glass assembly?
Will insulating performance be restored?
Could fogging return?
What does the warranty cover?

Avoid drilling glass, applying improvised sealants, or covering drainage openings. These shortcuts can create additional problems without resolving the failed seal.

Should You Replace the Glass or the Skylight?

Glass replacement may be appropriate when compatible glazing is available and the frame, operating components, and roof connection remain sound. This approach addresses the failed insulated unit without automatically replacing everything.

Full replacement becomes more compelling when the frame is deteriorated, hardware is failing, leaks recur, or replacement glass is impractical. The skylight’s age and overall condition should guide the decision.

Check existing warranty coverage before approving work. Installation records, manufacturer information, photographs, and approximate age can help clarify the available options.

What Should You Do Before Winter?

Record changes in visibility and report ceiling stains, active drips, cracked glass, or damp trim separately. These symptoms may indicate problems beyond glazing failure. Arrange an assessment before assuming that humidity control, fresh caulk, or cleaning will solve the issue.

Discuss Your Skylight With Aluplex

Contact Aluplex to discuss persistent fogging, suspected failed skylight seals, or an aging unit before winter conditions complicate repairs. The company offers residential and commercial skylights, repair, installation, and replacement services. Explain whether the haze is trapped between panes and mention accompanying leaks or operating problems.

Request an assessment to understand whether replacement glazing or a new skylight better suits the existing installation, rather than choosing a cosmetic treatment that leaves the underlying issue unresolved.

7 Roof Ventilation Errors That Trap Winter Moisture

September 30, 2026 By Webmaster

Wet glass in winter does not always mean a window or skylight leaks. Roof ventilation can help clear damp air from a vented attic, but it cannot fix a bad seal, a cold light shaft, or a bath fan that dumps steam above the rooms. Start by noting where the water sits and when it shows up. Those clues can help you seek the right fix.

1. Blaming Every Wet Pane on the Roof

A cold pane can turn damp room air into drops of water. Roof ventilation will not dry that pane if the damp air stays in the room. The same is true of a skylight frame that feels cold to the touch.

Check the glass on a dry, cold day. Can you wipe the drops from the room side? Do they come back after a shower or long cook time? If so, start with indoor air flow. Run the bath fan, use a range hood that vents outdoors, and wipe up drops so they do not soak the trim.

The side of the glass that gets wet is a key clue. Fog that you cannot wipe from the pane may sit between its layers. That can point to a failed glass seal, which calls for a glass check rather than more attic vents.

2. Letting Bath Fans Send Steam Upstairs

A bath fan should carry damp air outdoors. If its duct ends in the attic, it can coat cold roof wood with frost. The frost may melt and drip when the attic warms, leaving a stain that looks much like a roof leak.

This fault can also harm the area near a skylight shaft. Warm, wet air may meet cold parts near the shaft and leave damp marks on the wood or trim.

Check where the duct ends, not just if the fan runs. Ask a pro to fix a duct that stops in the attic. Do not step off a safe walk path or climb onto bare drywall to trace it on your own.

3. Blocking the Low Vent Path

In a vented attic, air may enter near the eaves and leave near the peak. Loose fill or batts can block the low vents from the inside, even if the vents look clear from the yard.

A poor air path may let damp air stay near the roof deck. It may add to frost or wet spots near a light shaft, though it will not by itself prove that a wet window or skylight has a roof fault.

Ask a pro to check the soffit vents from inside.
Keep fill out of the air path where baffles belong.
Do not strip away fill to make a large gap.

Clear vents and sound fill must work as a pair. The aim is an open path for air above the fill, not a cold room below it.

4. Missing Air Leaks at the Light Shaft

A skylight shaft links a warm room to the roof. Gaps where the shaft meets the ceiling can let warm, damp air rise. Thin fill at the shaft can also leave cold spots on its inner face. Drops may then form on the trim or near the frame.

Look for paint that peels, dark marks, or a chill near the shaft on cold, dry days. Take a photo and note if the mark grows with rain. Both a room-air fault and a roof leak can leave water near the same spot.

A wet shaft needs a full check. A pro may need to look at the air seal, fill, skylight frame, and roof area before they can name the cause.

5. Treating Worn Seals Like an Attic Fault

An open window or vented skylight needs a snug seal when shut. Worn strips may let cold air in and make the frame feel drafty. A crack in the glass, a worn seal at the pane, or a gap at the frame may also let water in.

You can check for clear signs from the room side:

A sash that will not shut all the way.
A strip that has split or come loose.
Fog set deep between glass panes.
A drip that starts at the frame in rain.

Do not add a roof vent to fix a worn glass seal. A window or skylight pro can check if the part needs a new seal, new glass, or a larger repair.

6. Adding Vents Without Knowing the Roof Type

Not all roofs use the same air path. Some have a vented attic; some use a sealed roof plan. A new vent in the wrong spot may not help and could upset the way that roof keeps out damp air.

Ask how the roof was built before you ask for more vents. The check should cover the ceiling air seal, the fill, and the vent path, if there is one.

More vents are not a cure for each wet spot. A sound plan starts with the roof type and the source of the water.

7. Missing a Leak Near the Glass

Damp air can form drops on a pane, but rain and snowmelt can also find a route past a roof joint or skylight frame. Track the time of each drip. Does it show up on cold, dry days, or only as rain falls and snow melts?

A stain that grows after a storm needs prompt care. So does soft trim or drywall that stays wet. Do not cover the mark with paint or a quick bead of caulk before the water path is known.

Check the unit and the roof as one area. If the roof is sound, the fault may lie at the glass or frame. If the unit is sound, the roof or light shaft may need work.

For more on unit care, see Aluplex’s skylight guide and its FAQ on glass, seals, and damp spots.

If a window or skylight drips, fogs up, or leaves a stain, ask Aluplex to check the glass and frame. Share photos and note when the wet spot forms. The team can look at the unit and the area near it, then help you plan the next step. If the cause sits in the attic air path, ask a roof pro to check that space as well. Contact Aluplex to book a glass or skylight check before the wet spot grows.

Is Skylight Condensation a Leak? 5 Telltale Clues

September 23, 2026 By Webmaster

Water on a skylight does not always mean rain got through the roof. Skylight condensation forms when damp indoor air meets cold glass or a cold frame; a leak brings water in from outdoors. Both can harm paint, trim, and drywall, so it pays to find the source rather than wipe up the drip and hope it stops.

1. Check When the Water Shows Up

The first clue is timing. Skylight condensation may form on a cold, dry day, while a roof leak is more apt to show up as rain falls or snow starts to melt.

Think back to what took place in the home. Did the glass fog up after a shower, a long cook time, or a load of wet gear came indoors? Damp air rises, and a cold pane can turn that air into drops of water.

Keep a brief log for a week:

Note when the drops start and when they dry.
Note if rain, snow, or a thaw took place.
Take a photo before you wipe the water away.
Mark any link to baths, meals, or lots of guests.

A clear pattern can help trace the source. Water that shows up only in cold, dry weather may point to indoor air. Water that starts with each storm calls for a roof check.

2. See Where the Water Sits

Look at the pane from inside the room. Drops spread over the glass or frame may come from damp air in the room. If you can reach the pane with no risk, wipe a small spot dry and watch to see if the drops come back.

Fog that stays put when you wipe the room side may sit between the panes. That can mean a seal in the glass has worn out. A failed glass seal does not prove that rain has got into the roof, but it does need a closer look.

Do not climb onto the roof to test the outer glass. A safe check from the room side gives you clues; a pro can check the parts you cannot reach.

3. Trace the First Wet Spot

Water can run down a frame and pool on the sill. It can also move along wood or drywall before you see a stain. For that reason, the spot where water lands may not be the spot where the fault began.

Look for these signs:

Drops that form on the pane and run to the sill.
A stain that starts at the top of the light shaft.
Soft trim or paint that peels near one corner.
A mark that grows after each storm.

A stain beyond the frame needs a prompt check. It may point to a roof or flash fault, though damp air in the shaft can leave a mark there too. Do not paint over the stain until you know why it formed.

4. Look for Damp Air Elsewhere

A wet skylight may be one sign of damp air in the home. Check nearby glass, cold walls, and other rooms. If more than one pane beads up on cold days, the air in the home may need more flow.

Use bath fans when you shower and a range hood that vents outdoors when you cook. Let room air reach the skylight; a blind shut tight for long spans may leave the glass cold and still. Wipe up drops so they do not soak the frame or trim.

Less drip after better air flow is a useful clue, not a final test. A home can have damp indoor air and a roof leak at the same time. If stains keep on growing, book a site check.

5. Watch for a Pattern That Gets Worse

One foggy pane on a cold day is not the same as a new brown stain each time it rains. Check whether the wet area grows, how long it stays damp, and if the wood feels soft. A stale smell near the shaft may also point to water that has sat too long.

Do not pack fresh caulk over a seam as a first fix. That may hide the route water takes and make the true fault hard to find. A pro can check the glass, seals, frame, flash, and roof area as one set of parts.

The right fix starts with the right cause. A worn glass seal, a wet light shaft, and a roof leak call for quite different work.

To learn more about unit types and repair work, see Aluplex’s skylight page. Its FAQ also has tips on foggy glass, seals, and care.

If you have drips, fog set deep in the pane, or a stain that will not dry, ask Aluplex to take a look. Share your photos and notes on when the water shows up. The team can check the unit and the roof area near it, then talk you through the next step. Book a site visit before a small wet patch turns into a much larger task.

Beat Stale Rooms With This Brilliant Ceiling Upgrade

August 31, 2026 By Webmaster

Stuffy rooms drag down mood and focus fast. A simple fix for that stale air problem comes in the form of fresh air skylights built right into your roof.

Why Rooms Get Stale in the First Place

Rooms with few windows or low airflow trap heat, moisture, and odors. Over time, that stuck air can feel heavy and hard to shake off.

A few common causes of stale air:

Rooms far from outer walls with no window
Closed floor plans that block cross breeze
High use spaces like kitchens or gyms
Homes with tight seals that trap heat in

Adding fresh air skylights gives stuck air a real path out, while also letting in natural light from above.

The Link Between Light and Mood

Natural light does more than brighten a room. Studies on office and home spaces link daylight to better focus, lower stress, and steadier sleep cycles. People who work near real light tend to feel less tired by mid-day. Even short bursts of sky light can lift mood and sharpen the mind during a long shift.

Rooms lit only by bulbs often feel flat, even at noon. A roof vent that lets in real sky light changes that feel almost right away.

How These Roof Vents Work

Unlike a fixed glass panel, this style of skylight can open like a hatch. Fresh air moves in while warm, stale air rises and exits through the gap.

Key parts of a good unit:

A vent frame that opens by hand or remote
A seal that closes tight when shut
Screens to block bugs while open
Flashing that keeps rain out even when vented

Many models pair a remote control with a rain sensor, so the vent shuts on its own if a storm rolls in.

Best Rooms for This Upgrade

Not every room needs one, but some spaces gain the most from added light and airflow. Think about these spots first:

Kitchens, where cooking builds up heat and smell
Bathrooms, where steam and damp air linger
Home gyms or hobby rooms with heavy use
Attics turned into living space with poor airflow

Adding one vent to a room used often can shift how that space feels day to day.

Cost and Energy Trade-Offs

Homes with steady airflow rely less on air units running non-stop through hot months. Over a year, that lower load can shave real money off your power bill. Some owners see the price gap close within a few seasons. Others take longer, based on climate, room size, and how often the vent stays open.

In cold months, closed seals keep heat from slipping out. Look for units with double or triple glass layers to cut heat loss even further.

What to Ask Before You Buy

Before you pick a model, ask a few sharp questions:

Does it open by hand, crank, or remote?
What is the seal rating for wind and rain?
How thick is the glass, and what is its heat rating?
Does the warranty cover both glass and frame?

A clear answer to each shows you are working with a team that knows their product well.

If your rooms feel closed in or heavy with old air, a vented roof window might be the fix you have been missing. Aluplex builds and fits these roof vents across homes and buildings, matching each unit to the room it serves. Talk to Aluplex about which model fits your space and start breathing easier at home.

Could a Dripping Skylight Hide a Bigger Roof Failure?

August 28, 2026 By Webmaster

A drop of water on your floor may seem minor at first glance. Often, that small drop points to a leaking skylight repair need before the harm grows worse.

What Causes a Skylight to Leak

Most leaks start where the glass meets the roof frame. Over time, seals dry out, flash bends, or foam gaps open up.

A few common causes:

Worn or cracked seals around the glass edge
Loose or rusted flashing
Poor slope that lets water pool
Old caulk that has lost its grip

Each of these lets water sneak past the barrier meant to keep it out.

Once water gets in, a leaking skylight repair job often becomes urgent. A tiny drip today can soak wood beams and drywall within weeks.

Signs You Should Not Ignore

Some signs are easy to miss until they turn into a bigger mess. Watch for these clues around your skylight:

Dark rings or stains on the ceiling
A musty smell in the room below
Peeling paint near the frame
Soft or sagging drywall
Mold spots on trim or wood

If you spot even one of these, it is time to look closer at the roof line.

Why Small Drips Often Mean Bigger Trouble

A skylight sits at a break point in your roof. That break point takes more stress than flat roof areas during storms, wind, and heat swings.

When a seal fails, water does not always show up right where it enters. It can travel along a beam or rafter and drip out feet away from the real gap.

This means the stain you see may not match the source at all. A roof crew with the right tools can trace the path and find the true weak spot.

What a Proper Fix Involves

A good fix goes past just adding more caulk on top. Here is what a solid job should cover:

Remove old flashing and check for rust or rot
Replace worn seals with fresh, weather-grade material
Reset the frame if it has shifted
Test the fix with water before calling it done

Skipping steps may stop the drip for a short time but rarely solves the root cause.

When to Call a Pro Instead of a DIY Fix

Climbing on a roof is risky, and skylight frames often need exact tools to reset well. A missed step can turn a fix into a bigger tear in the roof skin.

Hire a team that works with skylights daily, not just general roof jobs. Ask about their process for tracing leaks and how they test their work after the fix.

Keeping Your Skylight Leak-Free Long Term

Once fixed, a bit of care goes a long way. Try these habits:

Clear leaves and dirt off the glass each season
Check the frame edge after big storms
Look inside near the skylight once a month
Book a check-up every few years, even with no visible drip

Small habits like these often stop a new leak before it starts.

If your roof shows any of these warning signs, do not wait for a small drip to become a large repair bill. Aluplex has installed skylights across homes and buildings for years, and their crew knows how to trace a leak back to its true source.
