Factors to Consider When Choosing Replacement Arched Windows

When selecting replacement arched windows, it’s important to consider various factors to ensure you make the right choice. Let’s explore some key factors you should take into account during your decision-making process.

Arched Window Types

Different arched window types offer varying functionality and design elements. Here are the most common types of arched windows:

  1. Fixed Arched Windows: These windows are stationary and do not open for ventilation or act as an escape route during emergencies. They are popular due to their low-maintenance design and weather-proofing capabilities. Pairing fixed arched windows with other operable window styles can provide both natural light and ventilation.
  2. Opening Arched Windows: These arched windows are operable and typically come in double-hung or casement styles. Double-hung arched windows offer obstructed views but have better locking and opening mechanisms. Casement arched windows provide a wide opening with an unobstructed view.
  3. Multi-Window Arched Windows: Instead of a single arched window, some companies create an arched look by aligning multiple rectangular windows with a semi-circle window above. While these are not technically arched windows, they offer a similar aesthetic appeal and are often offered as specialty windows.

It’s essential to check the warranty offered by the window brand you are considering. The length and coverage of warranties can vary significantly between products. High-end options, such as wood windows, typically come with comprehensive warranties, while cheaper alternatives like vinyl windows may have shorter warranties.

Window warranties generally include two components: workmanship and components. A lifetime warranty is an indicator of quality customer service and a secure investment. Ensure that the warranty covers all necessary elements, including screens, glass, and other components, as well as installation.

Reading reviews from customers on reputable sites like the Better Business Bureau (BBB), Trustpilot, and Google can provide valuable insights into a window brand’s reputation and customer satisfaction. Pay attention to both positive and negative reviews, focusing on aspects such as window and installation quality, warranty support, and the helpfulness of customer service representatives. A company with consistently negative reviews may not be the best choice for your arched window replacement.

Arched Window Replacement Cost

Arched windows add a touch of elegance and architectural interest to any home.
