Twin Cities double-hung window — the common repair candidate for fogged IGU, broken balance, and sash issues

What we repair

Five window repairs we do every week

Fogged glass, broken sashes, hardware failures, screens, and drafts. Most jobs finish same-day or within a parts-order cycle.

Fogged glass

Failed insulated glass units (IGUs)

When the seal around your double-pane glass breaks, moisture gets between the panes and the window fogs permanently. The fix is an IGU swap — the glass unit only, not the whole window. Typically $300–$800 per pane installed for standard sizes. Custom shapes and oversized panes run higher.

Broken sash

Cracked frames and stuck operators

A dropped sash, a balance that's let go, or a cranked casement that won't close. Sash repair runs $200–$600 per window when parts are available. Older Hurd and Marvin operators we can usually source.

Hardware

Locks, latches, balances, cranks

Window hardware wears out long before the window does. Replacement balances, casement operators, sash locks, and tilt latches typically run $150–$400 per window including parts.

Screens

Re-screen or replace

Re-screening an existing frame is the cheapest fix — $40–$90 per screen. Full screen replacement when the frame is bent or corroded runs $90–$200 per window depending on size.

Drafts

Weatherstripping, gaskets, and air-seal repair

Cold air at the sash, condensation on the frame, or curtains that move when the window is closed. Weatherstripping replacement and re-seating runs $100–$400 per window. If the frame itself has failed, we'll tell you — that's a replacement conversation, not a repair one.

Decision framework

Repair or replace? An honest framework

Most Twin Cities contractors push replacement on every call. We don't. Here's how we actually think about it.

Repair

Repair when the frame is sound

Frame square, no rot at the sill, fewer than 30% of windows in the house showing failure, and parts are still available. Examples: fogged IGUs on a 12-year-old Pella, failed balances on an Andersen 200-series, broken cranks on Marvin casements. Repair is the right call and we'll quote it.

Replace

Replace when the frame has failed

Rotten sills, racked frames out of square, single-pane windows from the 1970s, or more than half the windows in the house failing in the same season. Repair money is good money thrown after bad. We'll quote full replacement instead.

Parts question

Parts availability dictates a lot

Andersen, Pella, and Marvin keep parts catalogs going back 20+ years. Defunct lines (older Hurd, Caradco, EagleWood) sometimes can't be sourced. If we can't source the part, repair isn't on the table — and we'll tell you up front.

Brand patterns

Common issues we see in Twin Cities homes

Most Twin Cities repair calls fall into a handful of brand-specific patterns. Here's what we see — and what we can fix.

Andersen — fogged IGUs and balance failure

The 200-series and 400-series double-hungs we see most often show seal failure at the 15–20 year mark. Andersen still stocks balance kits and IGU replacements for both lines — we source them direct. Most jobs finish in one visit once the parts arrive.

Pella — operator cranks and screen frames

ProLine and Architect Series casements fail at the operator — the crank handle strips or the gearbox seizes. Replacement operators are still in production for both lines. Pella vinyl screens bend at the corners; we re-frame on site.

Marvin and Hurd — sash drops and hardware sourcing

Marvin Integrity and Ultimate sashes drop when the balance fails — usually a fix, not a replacement. Older Hurd lines (pre-Sierra Pacific buyout) get harder to source every year; we'll check before quoting.

Process

How a Modex window repair runs

Assessment, sourcing, install. Most repairs close inside two weeks from the first call — sometimes same-day for stocked hardware.

On-site assessment

We look at the windows, identify the brand and model, and tell you whether repair is the right call or whether replacement is the honest answer. Free for one to four windows; quote-only for larger surveys.

Source the right parts

Andersen, Pella, Marvin, and ProVia parts ship in 5–14 business days. We confirm the part with the manufacturer before quoting so you don't pay for a repair that turns into a discontinued-line dead end.

Install and warranty

Most repairs install in one visit. Modex workmanship warranty applies to the repair scope; manufacturer parts carry their own warranty terms (1–5 years typical, lifetime on some premium IGU swaps).

Cost

Window repair pricing across the Twin Cities

Per-window pricing for the three most common repair scopes. Parts, labor, and workmanship warranty included. Custom sizes and discontinued lines run higher.

Questions

The questions Twin Cities homeowners ask before booking a window repair.

How much does it cost to replace a fogged window pane in Minneapolis?

Most fogged-pane (IGU) replacements run $300–$800 per pane installed for standard sizes. That includes a custom-ordered insulated glass unit matched to your frame, Low-E coating, argon fill on most units, and Modex workmanship warranty on the swap. Oversized panes, custom shapes, and decorative grilles run higher. A 10–20 year manufacturer seal warranty applies depending on brand. If three or more panes are fogged at once, see our window replacement cost guide — at that scale full replacement starts to make sense.

When is window repair worth it vs full replacement?

Repair when the frame is square, the sill isn't rotted, fewer than 30% of windows in the house are failing, and parts are still available — typical for windows 5 to 20 years old. Replace when sills have rotted, frames are out of square, the windows are pre-1980 single-pane, or more than half the house is failing at once. We'll tell you honestly which side of that line your house is on at the assessment. If replacement is the right answer, see window replacement in Minneapolis.

Can you repair windows that are 30 or 40 years old?

Sometimes — it depends on the brand and whether parts are still in production. Andersen and Pella keep parts catalogs going back 20+ years; we can usually repair anything from those lines. Older Hurd (pre-Sierra Pacific buyout), Caradco, and EagleWood lines get harder to source every year. At 30+ years old, the frames themselves are usually compromised even when parts exist — most homeowners are better off with full replacement. We'll check parts availability before quoting either way.

What warranty comes with a window repair?

Modex workmanship warranty covers the repair install for the duration we stand behind labor on that scope. Replacement parts carry the manufacturer's own warranty — typically 1–5 years for hardware (cranks, balances, locks), 10–20 years for insulated glass unit seals, and longer on premium IGU swaps. We give you the part number, the manufacturer warranty terms, and our workmanship terms in writing before the work starts. No verbal-only promises.

Does homeowners insurance cover window repair?

Insurance covers sudden damage from a covered peril — hail, wind, tree-fall, vandalism, break-in. It does not cover wear-and-tear failures: fogged IGUs from a failed seal, balances that wore out, weatherstripping that aged out. If a storm broke a window or hail cracked a pane, file a claim and we'll document the damage for your adjuster. For seal failure and hardware failure, you're paying out of pocket — but repair scope ($150–$1,500/window) is cheap enough that most homeowners don't miss the insurance route.

Can you repair Andersen, Pella, and Marvin — not just the brands you install?

Yes. Modex installs Kolbe, Pella, and ProVia as our new-construction and replacement lines, but we repair every brand we can source parts for. Andersen 200/400 series, Pella ProLine and Architect Series, Marvin Integrity and Ultimate, older Hurd, Weather Shield, and most other major brands. The constraint is parts availability — not brand loyalty. We'll confirm sourcing before quoting.

Ready to fix the window?

Call Modex for a repair assessment. We'll tell you whether repair is the right call or whether replacement is the honest answer — and quote accordingly. No high-pressure follow-up.
