Frequently asked questions
Good questions deserve straightforward answers.
Every home is different. These are starting points; we’ll help you work through the details for yours.
How do I know when it’s time to replace my windows?
Drafts, condensation between panes, difficult operation, visible deterioration, and outdated appearance can all be signs. We can evaluate what you have and help you decide what makes sense.
How much do replacement windows cost?
Pricing varies by size, style, material, glass package, installation requirements, and coastal or impact options. We provide a customized estimate based on your home and goals.
Do I need impact-rated windows in Charleston?
Requirements and the best choice depend on the property, location, opening, and applicable code requirements. We’ll help you understand the appropriate options for your project.
Will new windows make my home more energy efficient?
Modern glass packages, Low-E coatings, improved seals, and reduced air infiltration can improve comfort and efficiency. The right package depends on your home.

No. Projects can often be completed all at once or in phases depending on your priorities and budget.
