What Actually Failed

Where the Money Goes on a Foggy Window

Before anyone quotes you a price, it helps to know what actually broke, because that's the only thing you should pay to fix. In a foggy window it's one part: the sealed glass unit. Two panes, a hollow spacer between them, a butyl seal around the edge, and 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.

How the fog got there. Years of hot days and cool nights flex the butyl until it opens. Moisture gets in, and the desiccant soaks it up like a bathtub filling. You see nothing until the tub is full, and then the water comes out on the glass. In Chapel Hill's older homes the seals have simply had more years of that flexing.

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.

So what are you paying for? A new sealed unit built to your glass size, and the labor to swap it into the frame you already have. Not a new frame, not new trim, not paint. The price follows the size of the glass, from $198 for a standard unit, and the number goes in writing before any work.

What you don't need. A teardown quote. If the frame and sash are solid, and they usually are, the glass unit is the whole repair. We build it ourselves, most of them the same day, and back the new seal with a 5-year written warranty.

Durham-Chapel Hill Inventory Surges as Prices Cool for Buyers - Realtor.com

With inventory surging and prices cooling in the Durham-Chapel Hill area, buyers now have more leverage during the inspection process. Home inspectors often flag foggy sealed glass units, which we can replace starting from $198, or sliding door rollers from $475. Fixing these small items now prevents buyers from demanding expensive credits for new vinyl windows at $1,000+ or a new patio door at about $10,000.

Cities with the fastest-growing home prices in North Carolina - Stacker

With home prices growing quickly across North Carolina, buyers in Chapel Hill should look closely at window and door conditions during walkthroughs to price their offers accurately. Many issues are simply failed parts rather than a need for a new vinyl window at $1,000+ or a new patio door about $10,000. You might find a sash balancer for $175 if a window won't stay up, a casement crank for $275, or sliding door rollers from $475. We can also handle foggy or broken sealed glass units from $198 using our patent-pending mobile glass process.

5 Housing submarkets in North Carolina cities that smart tech relocations are targeting - WRAL

With smart tech relocations targeting specific North Carolina submarkets, Chapel Hill homeowners may see increased interest from buyers who scrutinize every detail. Inspectors often spot soft or rotted wood on window sills or sashes, a flaw sellers frequently underestimate until it becomes a negotiation point. We can rebuild a rotted sash from $375 or a sill or frame from $475, 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 Money Question

What Foggy Windows Actually Cost to Fix in Chapel Hill

Let's answer the question you actually typed: glass-only repair starts at $198 per unit. A replacement window starts around $1,000 — five times more — and Chapel Hill's older homes usually have nothing wrong with the window itself. The seal in the glass unit failed; the moisture is trapped between the panes; the unit swaps out alone.

  • Glass-only repair — from $198 per unit

  • Replacement window — $1,000+ per opening

  • A whole houseful of foggy panes still costs a fraction of new windows

  • Written per-window price before any work starts

Older Homes, Honest Fixes

Chapel Hill Homes Deserve Better Than a Teardown Quote

From mid-century ranches near campus to wooded family homes off Franklin Street, Chapel Hill windows have character worth keeping. Fog is a seal problem, not a window problem: we fabricate a new insulated unit to your window's exact size — rigid aluminum spacers, proper desiccant — and your frames, grids and trim never move. And if something else ails the window, our Chapel Hill window repair crew handles that too.

  • Original frames, sashes and grids stay

  • Units built in-house so the fog doesn't come back

  • Hardware, balancers and wood repairs available on the same visit

03/Glass-Only Swap

04/Clarity Check & Warranty

“I have three kids, and they accidentally broke the tempered glass on our door. I contacted WowFix, but I had to wait for weeks for a technician. Despite the wait, I can't complain because they offered a reasonable price, and their technician did an excellent job replacing the glass.”

Foggy Window Repair in Chapel Hill — FAQ

From $198 per insulated unit, priced in writing per window before we start. Size, glass type (Low-E, tempered) and access set the final number. For contrast: every replacement quote you've collected starts around $1,000 per window — the repair is a fraction of that, which is exactly why replacement companies don't offer it.
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.
