Greater Columbia housing stock and conditions
Richland and Lexington counties hold 1960s-1980s stock with aluminum single-pane windows plus significant post-2000 growth in Lexington, Irmo, and Blythewood with builder-grade vinyl.
Long, humid summers make solar heat gain control the priority in most Low-E glass selections, and older aluminum frames show condensation problems that newer buyers frequently ask about.
- Condensation complaints on older aluminum single-pane frames are a frequent inquiry trigger
- Solar-control Low-E coatings are the default glass package given the length of the cooling season
- 1960s-1980s full-frame aluminum-to-vinyl conversions lead local project volume

Midpoint of the typical range for each project type.
| Project | Greater Columbia range | National range |
|---|---|---|

Whole-home vinyl replacement Every opening replaced in one pass with mid-range Low-E vinyl inserts, existing frames kept where sound. | $8,000 – $18,000 | $9,000 – $20,000 |
Whole-home fiberglass or wood-clad Same coverage in a premium frame material, narrower sightlines and paintable exteriors, often part of a facade update. | $14,500 – $34,000 | $16,000 – $38,000 |
Full-frame tear-out (8 openings) Frames, sills, and trim removed to bare rough opening so rot can be repaired and the opening flashed and insulated properly. | $7,000 – $18,000 | $8,000 – $20,000 |

How Lexington compares with the national picture
The national direction is consistent everywhere: Low-E coated, gas-filled glass is the baseline spec, vinyl takes most openings with fiberglass gaining at the top of the market, and insert replacement handles same-size openings unless the sills have failed. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
