Foggy Window Repair in Dunwoody, GA

Why Your Replacement Windows Are Fogging Now

A lot of Dunwoody houses already had their original windows replaced once. The sealed glass units in those replacements have their own clock, and many of them are now running out of time.

How a sealed glass unit fogs, from new to fogged and back A whole window with a magnifier on the edge of its lower glass unit. Day and night the gas between the panes heats and cools, the panes flex and the seal at the edge works. The butyl seal opens a hairline gap and water gets in. The desiccant inside the spacer soaks it up like a bathtub filling, while the glass still looks clear. When the tub is full, the water evaporates off the desiccant by day and settles on the inside of the glass by night, so the fog comes and goes, until it stays for good with white mineral streaks. The fix: a new sealed glass unit in the same window, clear again. the edge of the glass unit, up close room outside A new window Clear glass, sealed tight all the way around. Day and night, year after year Sun heats the gas between the panes, night cools it. The seal opens A hairline gap in the butyl. Water finds it. The tub fills The desiccant soaks it all up. The glass still looks clear. It overflows By day the water evaporates, by night it settles on the glass. Fogged for good Haze all day, white mineral streaks on the inside. We swap the glass unit Same window, a new sealed unit. Clear again. new flex opens fills overflows fogged new glass
The leak runs for years before you see it. The fog is the tub overflowing.

What's running out. A double-pane unit is two panes on a hollow spacer, sealed with butyl, with desiccant inside the spacer to keep the space dry. Every day the sun pushes the seal; every night it pulls back. When the butyl finally opens, moisture gets in and the desiccant soaks it up like a bathtub filling. When it's full, the fog shows.

Cross-section of a double-pane sealed glass unit (IGU) at its bottom edge Two panes of glass with a sealed gas space between them. At the edge, a hollow metal spacer holds the panes apart; it is filled with desiccant beads and has small holes facing the gas space. A thin butyl seal bonds the spacer to each pane and blocks moisture. Below the spacer, an outer sealant holds the unit together. The whole unit sits in the window sash.

Round two doesn't need a new window. The frames you paid for are usually still fine. Only the sealed glass unit failed, and that's the only part that needs to change.

What we do. We build a new sealed unit with fresh butyl and fresh desiccant to the size of your glass and set it into your existing frame. From $198 a unit, with a 5-year written warranty on the new seal.

Rough Draft Atlanta

Cities with the fastest-growing home prices in the Atlanta metro area - Stacker

With home prices growing quickly across the Atlanta metro area, Dunwoody sellers have a great opportunity to maximize their return. However, home inspectors often flag things like foggy glass units from $198 or sash balancers at $175, which can lead to expensive repair credits or price cuts at closing. Fixing a rotted sash from $375 or sliding door rollers from $475 now is far more cost-effective than replacing a new patio door for about $10,000 after the inspection. We provide a 5-year written warranty on our repairs to give both you and your buyer peace of mind.

2026 residential real estate forecast: Strong demand, limited inventory - Rough Draft Atlanta

With strong demand and limited inventory in Dunwoody, buyers may feel pressured to overlook maintenance issues during walkthroughs. Instead of pricing in a full window replacement at $1,000+ or a patio door at about $10,000, look for specific failed parts like a sash balancer for $175 or a casement crank for $275. Most issues are simple fixes, such as a window latch or lock for $115 or sliding door rollers from $475, rather than a need for entirely new units. We can provide the exact costs for these repairs to help you make an honest and fair offer.

The 30 cities in Georgia where homes are selling the fastest - WSB-TV

With homes moving quickly across Georgia, Dunwoody sellers need to be mindful of the small details that catch a home inspector's eye. A window latch or door lock that won't engage seems like a minor nuisance to a homeowner, but it can be flagged as a security or safety failure during a walkthrough. Fixing a window latch or lock costs $115 and a door lock is $175, which is a fraction of the cost of a new vinyl window at $1,000+ or a new patio door about $10,000. We handle these specific repairs so you can keep your home market-ready without replacing entire units.

First-generation insulated glass unit with moisture sealed between its panes in a Dunwoody home
The Seal Expired, Not the Window
The First Generation Ages Out

You Already Replaced These Windows Once. The Glass Remembers When

Walk the timeline of a typical Dunwoody colonial: built in the '70s with single-pane wood windows, then upgraded somewhere between 1995 and 2008 — either full new insulated windows or, very commonly here, add-on insulated glass sashes fitted into the original wood frames. Those first-generation sealed units carried seals engineered for a 15-to-25-year life, and the math has now come due across the Club Estates, Redfield and Georgetown almost simultaneously. The tell is unmistakable under the canopy: on a humid morning, the shaded windows wear a gray veil that sits inside the glass — no cloth touches it, from either face — then softens as the day warms, only to return at the next dawn. That's moisture breathing in and out of a cavity whose desiccant gave up long ago.

  • Haze or beads locked between the two panes, unreachable from either side

  • Worst at dawn on canopy-shaded elevations, fading by afternoon

  • '90s-2000s replacement and retrofit units — the cohort failing now

  • A white mineral bloom on the inner glass = the seal died a while back

The Wedge

Round Two Costs $198 a Unit — If You Skip the Salesman

Here's what the replacement industry won't lead with: everything you paid for in the '90s upgrade — the frames, the sashes, the trim carpentry, the paint — is still perfectly good. Only the factory-sealed glass sandwich inside it has expired, and that sandwich is a replaceable component. We measure your failed unit to the millimeter, fabricate a new insulated glass unit with rigid spacers, fresh desiccant and dual-seal edges built for Georgia humidity, and set it into the sash you already own. The add-on insulated sashes common in Dunwoody's older frames re-glass the same way. No demolition, no trim damage, no repainting — and no $1,000-plus-per-opening invoice for a second 'replacement' the house never needed.

  • Frames, sashes and trim untouched — glass only

  • from $198

    New IGU built to your exact measurements

  • Modern seals outlast the '90s originals they replace

I had a fantastic experience with WowFix. They repaired my existing windows by cutting out rotted sashes, fashioning new ones on-site, and splicing them in. They look and work absolutely good as new!

WowFix is a great company for repairs on doors and windows. I had two rotten double-door frames that they rebuilt. They communicate well and the pricing was fair.

Foggy Window Repair in Dunwoody — FAQ

Because 'already' is 25 years — a full service life for that era's factory seals. The desiccant inside the spacer absorbs stray moisture for a couple of decades, then saturates; after that, every humid Georgia night deposits a little more water between the panes. It arrives on schedule, not because your installer cheated you. The cure is a new sealed unit in your existing sash, from $198 per window.
Before We Arrive

How to Prepare for Your WowFix Window Repair Visit

  1. 1

    Photograph each problem window in daylight

    Snap a clear photo of every foggy, cracked or stuck window in natural light. Morning light shows fog between the panes best and lets us quote faster — often before we arrive.

  2. 2

    Note what each window is doing wrong

    Jot down the symptom per window — fog between the glass, won't open or stay up, draft, cracked pane, or rotted frame. It tells us whether it's a glass-only swap (from $198) or hardware/wood work.

  3. 3

    Clear about three feet in front of each window

    Move furniture, blinds and décor back roughly three feet so our crew can measure and work safely. It keeps the visit quick and your things out of the way.

  4. 4

    Find any window brand or paperwork

    If you have the original window brand, a sticker in the frame, or install paperwork, set it aside. It's not required, but it helps us match glass and parts on the first trip.

  5. 5

    Make sure we can reach the windows outside

    Unlock gates, secure pets, and clear the exterior path to the windows. Most glass-unit work is done from both sides, so outside access keeps everything one visit.
