Window Repair Specialists

Most windows don't need full replacement.

Foggy glass, failed seals, worn balance hardware, stuck sashes, broken locks — these are all repairs that cost a fraction of a new window. The frame is usually fine. The opening is fine. Just one specific component has worn out or failed.

We repair double-hung, casement, sliding, awning, and specialty windows — vinyl, wood, aluminum, and clad-wood frames from all major manufacturers. Most repairs finish in a single visit once the parts are on hand.

When the math says repair doesn't make sense — the frame is rotted, multiple windows have failed seals, or you're chasing recurring problems — we'll tell you directly and walk through window installation options instead. The recommendation matches your situation, not our invoice.

Common Problems

Window problems we fix.

Six issues that bring most homeowners to a window repair contractor — and what's actually going on inside the window when each one shows up.

Foggy or Cloudy Glass

Moisture between the panes means the seal has failed and the gas fill is gone. We can replace the insulated glass unit (IGU) without replacing the whole window in most cases.

Broken or Cracked Glass

From small cracks to fully shattered panes — usually from impact or stress. We replace single-pane, double-pane, and triple-pane glass to match the original spec.

Stuck or Hard to Open

Failed balance springs on double-hungs, worn pivot bars, paint sealing the sash to the frame, or shifted jamb liners. Most are 30-minute fixes once diagnosed.

Drafts & Air Leaks

Worn weatherstripping, compressed bulb seals, or sash balances that no longer pull the window tight against the frame. Fixable without replacement most of the time.

Broken Hardware

Locks, latches, casement crank operators, sash balances, sash cords. We source replacement hardware from major manufacturers and install to factory spec.

Rotted Frames & Sills

Localized rot can sometimes be repaired with epoxy consolidant and patching; widespread rot usually means the frame needs replacement. We'll tell you which one your window is.

Repair Services

What we actually do.

Specific repairs for specific problems — itemized in your written estimate, not lumped into a vague service charge.

01

Glass Replacement

Cracked, broken, or foggy glass replaced. Single, double, and triple-pane options matched to your original glass package — including low-E and tempered where required.
02

Insulated Glass Unit (IGU) Swaps

When the seal between panes fails, we replace just the IGU rather than the entire sash or window — typically 30–50% the cost of a new window.
03

Hardware Replacement

Locks, latches, crank operators, sash balances, pivot bars, sash cords. We source from the original manufacturer when possible, and quality aftermarket suppliers when not.
04

Weatherstripping

Worn or compressed weatherstripping replaced with the correct profile for your window — the cheapest possible fix for drafty windows that are otherwise sound.
05

Frame & Sill Repair

Localized rot consolidated with epoxy and patched. Damaged interior or exterior trim replaced to match. We address the moisture source so the rot doesn't return.
06

Emergency Glass Service

Broken windows from storms, accidents, or break-ins boarded up immediately, then properly replaced. Same-day temporary closure available for security and weather.
Our Process

How a window repair works.

Five steps from first call to a working window. Most repairs wrap up the same visit once parts are confirmed.

01

Inspection

We diagnose the actual cause — not just the visible symptom — and check for related issues nearby.

02

Estimate

A written, no-obligation estimate that itemizes parts and labor by window.

03

Source Parts

We source the correct replacement glass, hardware, or weatherstripping for your specific window.

04

Repair

Most repairs finish in a single visit. Custom-order glass may require a second appointment.

05

Test

We confirm operation, lock function, and air seal before signing off on the work.

The Reasonable Difference

Why homeowners trust our repairs.

Honest math, fast service, and quality parts — without the upsell pressure to replace what's still salvageable.

Honest Repair-or-Replace Math

If the repair is the better long-term value, we recommend the repair. If replacement makes more sense, we say so — and we won't push you toward whichever costs more.

Fast Turnaround

Most repairs are completed same-day or within a few days depending on parts availability. Custom glass orders take longer — we tell you exactly how long upfront.

OEM & Quality Parts

We source parts from the original manufacturer when available, and trusted aftermarket suppliers when not — never the cheapest stocking SKU we can find.

42 Years in Michigan

Decades of repair experience across every window brand and frame material. We know which problems are worth chasing, and which come back even after the repair.

Repair Costs a Fraction of Replacement

A glass-only swap typically runs 30–50% of a new window's installed cost. Hardware fixes are usually under $200. We'll show you the math, not just the headline.

Workmanship Warranty

Every repair is backed by our workmanship warranty. If a seal we replaced fails, or hardware we installed breaks because of how we installed it, we come back and fix it.

Window Repair FAQ

Window repair FAQs.

Costs vary by problem. Hardware replacement (lock, latch, balance) typically runs $75–200. Weatherstripping runs $100–300 per window. Glass replacement runs $200–500+ depending on size, type, and whether it's a single pane or insulated unit. We provide free written estimates with exact pricing before any work begins.
Yes — and it's typically the best-value repair we do. Foggy windows are caused by failed seals on the insulated glass unit (IGU). We can replace just the IGU rather than the whole window, usually at 30–50% of replacement cost. The frame, sash, and hardware all stay; only the glass package changes.
Repair makes sense when the frame is sound and only one component has failed — glass, hardware, or weatherstripping. Replacement makes sense when you have widespread seal failures, rotted frames, or windows 25+ years old with multiple issues. We'll inspect and tell you straight which way the math points.

Most repairs finish in 1–2 hours per window once parts are on hand. Custom-cut glass and IGU orders take a few business days to arrive — we'll book the install for after they're in stock, so you only deal with one appointment.
