How To Choose a Window Company in Dunwoody

Each window installer has unique offerings and approaches. To simplify the company search, keep these factors in mind:

Window Cost by Type

When you're shopping for new windows, it's crucial to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing budget windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The total cost of your window replacement will rely on the particular materials, sizes, and styles you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. It's wise to speak with a reliable installer to determine your ideal options.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window Types Average Cost
Arched $247-$1516
Awning $357-$995
Bay $823-$6109
Custom $366-$1018
Casement $285-$1651
Double-hung $133-$859
Egress $244-$610
Glass Block $48-$618
Picture $214-$1584
Single-hung $96-$1629
Skylight $122-$1470
Sliding $280-$1425
Storm $57-$402
Transom $298-$624

Window Material Cost

You'll also need to choose a window material. Homeowners frequently make their selection by considering aesthetic preferences, the local climate and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average Cost
Aluminum $57-$1629
Composite $588-$1321
Fiberglass $96-$823
Vinyl $198-$1832
Wood $294-$1651

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to take into account the cost of labor, warranties, and any other additional costs that your project may require.

Experience and Training

The longer a window company has been operating, the better its workmanship will likely be. Talk with a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often have photo galleries showcasing previous work technicians have done.

Licensing and Credentials

In Georgia, window installers are considered Drywall, Insulation, Studs & Acoustical Limited Service Specialty Contractors. They don't need a license to install windows or doors, but if their work extends beyond that scope, they will need a license.

Types of Windows Offered

No two businesses offer the same window styles and materials. Look for one that's an expert in the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the kind of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include vinyl, composite, aluminum, wood and fiberglass.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen different window replacement companies. Trustworthy sources for customer reviews include Trustpilot, Yelp, and Google Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in Dunwoody

How could new windows help my energy efficiency?

Dunwoody homeowners could save up to $360 each year by upgrading to efficient windows. They'll also reduce their property's carbon dioxide emissions by 480 pounds per year.

According to the national Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

What time of year should I replace my windows?

There is no "right" time to update your windows, but some seasons might be better than others depending on the local climate and a company's demand. Dunwoody experiences little to no wintertime snowfall, giving you more warm and dry days perfect for the job.

I broke my window's glass. Could I replace just the glass?

If your window has a shattered pane, it is not always necessary to replace the window frame. Often, only the glass pane needs to be replaced unless the frame has also suffered significant damage. A professional can determine exactly what's necessary during an estimate visit.
