The Key Question
IG Replacement vs. Full Window Replacement
We'll always tell you the honest answer — because sometimes IG unit replacement is the right call, and sometimes you genuinely need a new window. Here's how to tell.
| FACTOR | IG UNIT REPLACEMENT | FULL WINDOW REPLACEMENT |
|---|---|---|
| Frame condition | ✓ Good — no rot or warping | Frame is rotted, cracked, or warped |
| Issue | ✓ Foggy glass, broken seal | Structural failure, frame damage, drafts at frame |
| Hardware | ✓ Still functional | Broken, impossible to source replacements |
| Cost | ✓ 60–80% less expensive | Higher — but necessary when frame is the problem |
| Disruption | ✓ Minimal — often same day | More involved — typically full installation day |
| Best for | ✓ Seal failures, broken panes | Aged frames, major energy loss at frame perimeter |
During your free estimate, we'll assess your specific windows and tell you which approach makes sense — honestly.
Window Styles
Every Window Style — We Do It All
From classic double-hung to picture windows and everything between — we'll match your home's style and your ventilation needs.
Most Common
Double-Hung
Both sashes slide up and down independently. Easy to clean from inside — both sashes tilt in. Classic look that suits nearly any home style. Available in virtually every size.
Great Views
Picture / Fixed
A single, non-opening pane — maximizes the glass area and view. Perfect for living rooms, great rooms, or anywhere you want an unobstructed panorama. Highly energy-efficient.
Energy-Efficient
Casement
Hinged on one side, opens outward with a crank. Provides excellent ventilation and seals very tightly when closed — one of the highest-performing window styles for energy efficiency.
Versatile
Sliding / Gliding
Panels slide horizontally. Great for wide openings where vertical clearance is limited. Simple operation and clean sight lines — works well in contemporary homes.
Ventilation
Awning
Hinged at top, opens outward from the bottom. Can stay open during light rain — excellent for bathrooms and kitchens. Often combined above or below a fixed picture window.
Classic
Bay & Bow
Projects outward from the exterior wall, creating depth and character. Typically includes a large center window flanked by angled side windows. Adds interior space and curb appeal.
Frame Materials
Choosing the Right Frame for Colorado
Colorado's climate — intense UV, rapid temperature swings, low humidity — is hard on windows. Here's how the main frame materials compare.
🪟 Vinyl (uPVC)
The most popular choice for good reason — excellent insulating value, immune to rot and corrosion, minimal maintenance, and budget-friendly. Holds up exceptionally well in Colorado's UV-intense environment. Our most frequently recommended option for residential replacement.
🌲 Wood / Wood-Clad
The warmest, most traditional look — natural wood interior with an aluminum or vinyl exterior cladding for weather protection. Highest-end aesthetic, excellent insulation, but requires more maintenance than vinyl. Premium pricing.
⚙️ Fiberglass
The strongest frame material available — dimensionally stable in extreme temperatures (no expansion/contraction), can be painted, and has the highest insulating value of any frame. Premium option, premium durability.
Why Replace Now?
The Benefits of New Windows
💡
Lower Energy Bills
New, properly sealed windows with Low-E glass and argon fill can reduce heating and cooling costs by 25–40%.
🏡
Curb Appeal & Resale
New windows are one of the highest-ROI home improvements — visible from the street and top-of-mind for buyers.
🔇
Sound Reduction
Double and triple-pane windows with argon fill dramatically reduce outdoor noise — traffic, neighbors, wind.
🔒
Better Security
Modern windows feature multi-point locking systems and impact-resistant options that aging single-pane windows simply can't match.

FAQs
Replacement Window Questions
How do I know if I need new windows vs. just IG replacement?
If the frame is structurally sound (no visible rot, warping, or cracking; hardware still operates; no drafts at the frame perimeter), IG replacement is almost always the better value. If the frame itself is failing, a full replacement is necessary. During your free estimate, we'll give you an honest assessment — we'd rather save you money if repair is the right answer.
What's the difference between a pocket replacement and a full-frame replacement?
▼
A pocket (or insert) replacement keeps the existing frame in the wall and installs a new window unit inside it — faster and less disruptive, but the viewing area is slightly smaller. A full-frame replacement removes everything including the frame and casing, then installs fresh — better when the existing frame is deteriorated or you want to change the window's rough opening size.
Do replacement windows qualify for tax credits?
ENERGY STAR-qualified windows may qualify for the federal Energy Efficient Home Improvement Tax Credit. The credit is up to 30% of the cost (up to certain limits). We'll identify which products qualify — and we recommend consulting your tax advisor for specifics on eligibility.
Will replacing windows impact my home's historic character?
We work with customers to find options that preserve original character while improving performance. Many manufacturers offer wood-interior windows and historically-appropriate simulated divided light patterns that maintain a traditional look while delivering modern energy efficiency.
