The housing stock driving Myrtle Beach, SC window replacements
Horry County is dominated by post-1990 construction, including a very large condominium and vacation-rental inventory alongside retirement community development, most of it originally built with standard double-pane vinyl or aluminum.
- Condo association approval and material restrictions shape window replacement scheduling and product choice
- Impact-rated glazing is increasingly specified in oceanfront and near-coastal buildings
- Rental turnovers favor low-maintenance vinyl over wood or aluminum frames
Local conditions that change the spec here
Salt air, high humidity, and coastal wind exposure are the defining constraints, and many properties near the immediate coastline face wind-borne debris requirements. Condo association rules add approval steps most single-family markets don't have.

How Myrtle Beach, SC 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.
