Frequently Asked Questions

What are the benefits of energy efficient windows?

Energy efficient windows are specially designed to prevent your heated or cooled air from escaping your home. By utilizing advanced glazing, inert gas fills, and superior weatherstripping, these replacement windows significantly reduce your monthly utility bills and keep indoor temperatures stable.

Are vinyl windows a good investment?

Yes, vinyl windows are an excellent investment for homeowners. They are highly durable, resistant to moisture and rot, and require almost no maintenance compared to traditional wood frames. Additionally, modern vinyl frames offer exceptional thermal insulation.

What makes double hung windows so popular?

Double hung windows feature two moving sashes (top and bottom), which provides versatile ventilation options for your home. They are also notoriously easy to clean, as the sashes typically tilt inward, allowing you to wash both sides of the glass from inside the house.

How long does professional window installation usually take?

The timeline for window installation depends on the number of replacement windows being installed and the condition of the existing frames. However, a standard whole-house replacement can often be completed by a professional crew in just one to two days.

When should I consider replacing my current windows?

You should consider replacement windows if you notice drafts near the sashes, condensation between glass panes, difficulty opening or closing the windows, or unexplained increases in your energy bills. Upgrading to energy efficient windows resolves these issues entirely.
