What Are Arched Windows?

Arched windows, sometimes called radius windows, consist of a rectangular bottom and half-circle top. These shapes may fit together as one window, or you may find the half-circle separated but directly over the rectangular window. The curvature adds contrast to a room with sharp angles. Not all arched windows open, which we discuss below.


Factors To Consider When Choosing Replacement Arched Windows

Knowing you want an arched window style takes care of one decision in the window-buying process, but there are a few more elements to figure out. First, you must decide which arched window and frame material works best for your needs. Once you find companies that offer what you’re looking for, you’ll need to check out warranty coverage and customer reviews to see which offers the most value for the price. 

Arched windows can vary in design and function. They typically fall into one of these three styles:

  • Fixed arched windows: Fixed arched windows bring in a lot of natural sunlight but don’t open, so they don’t provide ventilation or act as an escape during a fire. These windows are among the most popular styles due to their low-maintenance design and weather-proofing capability. We recommend pairing fixed-arched windows with other styles that do open. 
  • Opening arched windows: These are operable and often come in single-hung or double-hung styles. Double-hung arched windows have more obstructed views but better locking and opening mechanisms.
  • Multi-window arched windows: Some companies craft arched windows from different panes aligned in an arched configuration. Typically, window installers will use several rectangular windows with a semi-circle window above to create an arched look. Though these are not arched windows in the technical sense, many companies offer them as specialty windows, given they offer the same look and feel.

Once you know your style, determine the best material for your home and budget. There are five primary window frame materials to choose from: aluminum, vinyl, composite, fiberglass, and wood. 

Aluminum and vinyl windows are usually the most cost-conscious options. Aluminum is heavy-duty and lightweight, but it’s prone to rust and isn’t energy-efficient. Vinyl is more energy-efficient, durable, and low-maintenance, but it isn’t the most aesthetically appealing material. 

Composite is a mid-range option made from polymer resins and wood fibers. Composite windows are energy-efficient, strong, and long-lasting. They’re susceptible to fading, though, and aren’t that customizable. 

Fiberglass and wood windows cost the most. Fiberglass is incredibly strong, heat-resistant, low-maintenance, and energy-efficient. They come with a much higher price tag and the added fee of requiring professional installation. Wood windows are also expensive. Many homeowners like them for their classic curb appeal but are prone to rotting and warping, especially in humid climates.

Always read through the warranty before buying windows, and don’t purchase any without one. Window manufacturers typically offer lifetime or limited lifetime warranty coverage. Full lifetime warranties are ideal, as this means all components of your window are covered for the product’s lifetime. Limited lifetime warranties cover some parts of the window for the product’s life span. Most manufacturers link a sample warranty policy on their website. We encourage you to read the fine print to know the coverage terms. 

If your windows are professionally installed, your installer should also provide a labor warranty to cover workmanship. Labor warranties typically cover installation for 2–10 years.

Reading reviews on popular sites such as the Better Business Bureau (BBB), Trustpilot, and Google helps you understand customers’ experiences with a window brand.  Consider each reviewer’s pros and cons, especially window and installation quality. Many customers will mention whether or not a company stands behind its work with its warranties, as well as how helpful customer service reps are. You should consider a different installer if you notice many negative reviews.


How Much Does Arched Window Replacement Cost?

The cost of replacement arched windows aligns with the average cost of replacement windows, which is between $200 and $1,800 per window. Arched windows average higher in this range, starting around $500. These figures don’t include other cost factors, such as your home’s unique features, frame materials, and glass options. 


How Can I Save Money on Arched Window Replacement?

Save money on window replacement with these tips:

  • Buy windows in bulk: Some manufacturers provide discounts for buying a certain number of windows, so if you need multiple windows, you’ll save money buying them all at once. 
  • Check for discounts: Look on brands’ websites for any deals. Some companies will frequently offer discounts, such as getting two windows free for every two you buy.
  • Pick standard sizes and affordable materials: A standard window size is cheaper than custom sizes. A material such as vinyl offers quality while being dramatically more affordable than fiberglass or wood. 
  • Schedule installation in winter: Unless you have harsh winters, installers in your area are likely still looking for work in the cooler months. Scheduling in the offseason when work is slow could save you some money.

How Do I Find a Local Window Installer?

Arched windows are challenging to install yourself, so consider hiring a professional window installation company. Some window manufacturers offer installation in-house. If you purchase your windows from one that doesn’t, you must hire a third-party contractor. Always check that your contractor is properly licensed and experienced at installing this window type. Also, make sure they offer a labor warranty.

Our Conclusion

Many window companies produce arched windows, but only a few combine high-quality materials, comprehensive warranties, solid reputations, and fair pricing.
