At Apex Windows & Glass, we offer both services — and we're honest about which one you actually need. The answer depends on the condition of your window frames, the number of windows affected, and your long-term goals for the home. Here's how to think through the decision.
The Core Question: Are Your Frames in Good Shape? This
is the single most important factor. If your window frames are structurally sound — no rot, no warping, no significant air infiltration — then glass-only replacement (IGU replacement) is almost always the better value. You save 50–70% compared to full replacement and get the same result: clear, energy-efficient windows. Full window replacement is the right choice when the frames themselves are the problem.
When Foggy Glass Repair Is the Right Choice
- 1–5 windows are foggy and the rest are clear
- Frames are in good condition — no rot, no warping, no drafts
- Windows are less than 20 years old and otherwise performing well
- You want to minimize cost — glass-only replacement saves 50–70%
- You want minimal disruption — most glass replacements are done in a single visit Example: A Plano homeowner with 3 foggy windows in a 2010-built home. The frames are vinyl and in perfect condition. Glass-only replacement is the clear choice — cost-effective, fast, and the result is indistinguishable from new windows.
When Whole Home Window Replacement Is the Right Choice
- More than half your windows are failing simultaneously
- Frames are rotted, warped, or damaged — especially common in homes with wood frames
- You feel drafts around multiple windows despite having the glass replaced
- Your home is 25+ years old and windows have never been replaced
- You want to upgrade window styles or significantly change the look of your home
- You're preparing to sell and want maximum curb appeal and buyer appeal Example: A Fort Worth homeowner with a 1988-built home where 12 of 16 windows are foggy, several frames show wood rot, and there are noticeable drafts in winter. Full replacement is the right investment.
The Hybrid Approach Many
homeowners end up with a combination: glass-only replacement on windows where the frames are good, and full replacement on windows where the frames are compromised. This is often the most cost-effective approach and is something we assess during our free in-home evaluation.
