Foggy Window Repair in Decatur, GA

Cloudiness sealed inside double-pane glass means the unit's seal has died — the window itself is fine. We fabricate a replacement insulated unit to your opening's exact dimensions and exchange the glass alone, from $198, backed by a written 5-year warranty.

What Actually Failed

Why the New Glass Fogs and the Old Glass Doesn't

Decatur's oldest windows have a single sheet of glass. A single pane can't fog between the panes, because there's nothing between. Fog lives in double-pane glass, the sealed units that came later.

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.

How a sealed unit fails. Two panes, a hollow spacer, a butyl seal around the edge, desiccant inside to keep the space dry. Daily heat and nightly cooling flex the butyl until it opens. Moisture gets in, the desiccant soaks it up like a bathtub filling, and when it's full the fog appears on the inside of the glass.

Storm-window sweat is different. Water between an old window and a storm window wipes off once you open the storm. Fog inside a sealed unit can't be wiped from either side.

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.

Atlanta Housing Market Sees A Surprising Shift In Buyer Behavior - Patch

The recent shift in Atlanta buyer behavior means Decatur sellers need to be more strategic about how they present their homes. Home inspectors often flag foggy sealed glass units from $198 or rotted sashes starting at $375, which can lead to costly repair credits or price cuts far exceeding the actual fix. Addressing these issues now prevents buyers from demanding a new wood window at about $2,000 or a new patio door at about $10,000. We provide a 5-year written warranty on our repairs to give both sellers and buyers peace of mind.

The 30 cities in Georgia where homes are selling the fastest - Macon Telegraph

With homes selling quickly across Georgia, Decatur buyers need to be decisive but observant during walkthroughs. If you spot a window that won't stay up, it is often just a sash balancer for $175 rather than a new vinyl window starting at $1,000+. Other common fixes like a window latch or lock for $115 or a casement crank for $275 can be priced into your offer without assuming the whole unit needs replacing. We provide a 5-year written warranty on our repairs to give new homeowners peace of mind.

GA Housing Market Shows Shift Toward Buyers - Patch

With the GA housing market shifting toward buyers, Decatur sellers need to be more mindful of the small details that can stall a closing. A window latch or door lock that won't engage is a red flag for inspectors, though sellers often dismiss it as a minor annoyance. Replacing a window latch or lock costs $115 or a door lock $175, which is a fraction of the cost of a new vinyl window starting at $1,000+ or a new patio door about $10,000. We can get these security gaps fixed so they don't become negotiation points.

The Decatur Paradox

The Oldest Glass in Decatur Never Fogs — It's the New Glass That Does

Here's the joke the bungalow streets of Oakhurst and Winnona Park play on everyone: the wavy 1920s panes in those craftsman sashes have no seal to fail, so a hundred years on they're still perfectly clear. The fog shows up in what came later — insulated units retrofitted into old sashes during renovations, the glass in a kitchen addition, the double-panes of the midcentury ranches north toward Great Lakes and Decatur Heights. Those sealed units carry a perimeter seal with a finite life, and Decatur's deep oak canopy shortens it: shaded glass stays damp long after sunrise, the cavity breathes moisture at every pressure swing, and once the seal gives out, the haze moves in for good.

  • Permanent mist locked between two panes of glass

  • Retrofitted and renovation-era units fail first — not the antique sashes

  • Shaded north-side glass under the oaks holds fog longest

  • Beads or mineral streaks inside the cavity that no cloth reaches

The Wedge

Storm-Window Sweat vs. Dead-Seal Fog — Know Which One You Have

Half of Decatur's 'foggy windows' aren't seal failures at all. On houses running storm windows over original single-pane sashes, moisture often condenses in the air gap between the storm and the primary window — that's ventilation, not glass failure, and it clears when the space can breathe. True seal failure is different: the haze is locked inside a factory-sealed double-pane sandwich, unreachable from either face, morning after morning. That unit is done — and only that unit. We measure it to the millimeter, build a fresh insulated unit with rigid spacers and a desiccant-charged perimeter, and set it into the sash you already have. The sash stays, the trim stays, the paint stays; only the glass changes.

The Process

How Foggy Window Repair Works in Decatur

The glass is built before the truck rolls — so one firm-dated visit finishes the job.

01/Tell Dispatch What's Hazed

Call or book online and describe which panes stay cloudy. Dispatch places you on a scheduled metro-Atlanta route with a firm date — no floating 'sometime soon.'

02/Confirm the Diagnosis & Measure

On-site we distinguish dead-seal fog from storm-window condensation, then record width, height, thickness and spacer — and the written price — before anything is fabricated.

03/Build the Replacement Unit

Your new insulated unit is fabricated to those measurements with rigid spacers and a moisture-scavenging desiccant edge designed for shaded, humid Georgia lots.

04/Exchange & Warranty

The fogged unit comes out, the new one beds into fresh sealant, the glass is checked in daylight with you — and a 5-year written warranty covers the work.

  • Foggy window repair cost — $198–$480 by glass size and type · insulated glass unit guide · seal repair costs

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 Decatur — FAQ

Yes, and that's the whole design of the repair. The retrofitted sealed unit lifts out of the antique sash, a new unit built to identical dimensions goes back in, and the heart-pine sash, the trim and the paint never come off the wall. The century-old woodwork that gives the house its face is exactly what we work around, from $198 per unit.
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.
