Foggy Window Repair in Greensboro, NC

Fog, mist or haze between the panes means the seal failed — not the window. We build a new glass unit to size and swap only the glass, from $198, so the fog doesn't come back.

What Actually Failed

Foggy, Fogged, Cloudy, Misted: One Failure Behind All of Them

People in Greensboro call it a lot of things: foggy glass, a cloudy window, moisture between the panes, a pane that looks misted from the inside. It's all one failure, in one part. A double-pane unit is two sheets of glass on a hollow spacer, sealed around the edge with butyl, with a desiccant inside the spacer to keep the space dry.

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.

Humidity is what finds the weak seal. Every day the sun warms the glass and the trapped air pushes on the butyl; every night it pulls back. Once the seal opens, Greensboro's long humid summers keep damp air sitting right at the gap. It gets in, and the desiccant soaks it up like a bathtub filling. The tub fills quietly for a long time. When it's full, the water comes out on the inside of the glass, and the window looks foggy, then cloudy, then streaked.

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.

Why "get the fog out" doesn't work. The water is sealed inside, so nothing from the outside reaches it. Drilling and drying leaves the seal open and the desiccant full, so the fog comes back.

What we do. We build a new sealed unit with fresh butyl and fresh desiccant, most of them the same day, and set it into your existing frame. From $198 a unit, 5-year written warranty.

Guilford County’s Third Quarter 2026 Housing Market shows Rising Inventory, Declining Prices - YES! Weekly

With rising inventory and declining prices in Guilford County, sellers now face more scrutiny from buyers. A home inspector will often flag things like foggy sealed glass units from $198 or sash balancers at $175, which can lead to expensive repair credits or a price cut far exceeding the actual cost of the fix. Instead of replacing a wood window for about $2,000, we can rebuild a rotted sash from $375 to keep your listing value high.

Greensboro, NC, Has a Shortage of Homes for Middle-Income Earners - Realtor.com

With a shortage of middle-income homes in Greensboro, buyers may need to be more flexible with the condition of the properties they find. During your walkthrough, remember that many window issues only require a small part rather than a full replacement, such as a sash balancer for $175 or a window latch or lock for $115. Instead of pricing in a new vinyl window at $1,000+ or a new wood window at about $2,000, you can often simply replace a foggy or broken sealed glass unit from $198. We can help you budget honestly for these repairs to keep your offer competitive.

Is the war in Iran impacting the real estate market? - wfmynews2.com

Global tensions mentioned in recent news can create uncertainty for those buying or selling homes in Greensboro. A window that slams shut or won't stay up is a red flag for inspectors and buyers, though sellers often mistake a worn sash balancer for a minor nuisance. Replacing a sash balancer is $175, which is a fraction of the cost of a new vinyl window at $1,000+ or a new wood window at about $2,000.

The Seal Failed, Not the Window
Why It Happens Here

Greensboro Humidity Finds Every Weak Seal

Call it foggy, fogged, cloudy, misted — it's the same story: the factory seal around your double-pane unit gave out, and Triad summers pumped moist air into the gap. The moisture is between the panes, which is why no amount of cleaning touches it. The glass unit failed; the window around it is usually perfectly fine.

  • Haze or droplets you can't wipe from either side

  • Fog that comes and goes with the weather — early-stage seal failure

  • White mineral streaks where moisture dried between panes

  • One foggy window in a wall of clear ones — seals fail one at a time

The Wedge

Every Company Says Replace. We Re-Glass.

Window companies quote full replacement for fog because windows are what they sell. The honest fix: we fabricate a new insulated glass unit to your window's exact size — rigid aluminum spacers, proper desiccant, quality butyl — and swap only the glass. Your frame, sash and trim never move, and the new seal is built to outlast the one from the factory.

  • Glass-only swap from $198 — replacement runs $1,000+ per window

  • Our own units: rigid aluminum spacers, not soft foam that warps

  • Same window, clear view, written warranty on the seal

The Process

How Foggy Window Repair Works in Greensboro

Four steps from cloudy to crystal-clear — no frame removal, no drywall work, no repainting.

01/Confirm the Seal Failure

We verify the moisture is between the panes — not room humidity — and measure the exact unit: width, height, thickness, spacer.

02/Your Unit Is Fabricated

A new dual-pane insulated unit is built to spec in-house with rigid aluminum spacers and a desiccant-filled perimeter that locks moisture out.

03/Glass-Only Swap

The fogged unit lifts out, the new one seats into your existing sash. The frame never leaves the wall.

04/Clarity Check & Warranty

We inspect the glass in daylight with you and back the new seal with a written workmanship warranty.

Foggy Window Repair in Greensboro — FAQ

The sealed unit failed. Double-pane windows are two sheets of glass bonded around a sealed, desiccant-dried gap — when the seal gives out, Greensboro's humid air gets in and condenses where no cloth can reach. Only a new sealed unit fixes it, from $198, and your window stays in the wall.
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.
