How To Choose a Window Company in Ashburn

An exceptional reputation is key when it comes to choosing a window company. However, your chosen company should also align with your priorities and respect your vision. Think about the following factors during your company search:

Window Cost by Type

When it comes to replacing your windows, value is paramount. Each window you buy should provide unparalleled durability at a fair price point. Choosing budget windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The total cost of your window replacement will rely on the particular styles, materials, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's recommended to consult a reliable installer to decide on your most suitable 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 $235-$1446
Awning $341-$949
Bay $785-$5828
Custom $349-$971
Casement $272-$1575
Double-hung $126-$820
Egress $233-$582
Glass Block $46-$589
Picture $204-$1511
Single-hung $92-$1554
Skylight $116-$1403
Sliding $267-$1360
Storm $55-$384
Transom $284-$595

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your desired look, the local climate, and your energy efficiency goals. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window Types Average Cost
Aluminum $55-$1554
Composite $561-$1260
Fiberglass $92-$785
Vinyl $189-$1748
Wood $280-$1575

Other Window Replacement Costs

Ask each company you're evaluating about labor costs, warranty fees, and permit fees. This will help you get a clear picture of the financial commitment involved in the project.

Experience and Training

Examine a company's website and chat with a representative to learn more about its product and service offerings, pricing, and warranties. Many companies also keep online galleries that present past projects.

Ensure that the company specializes in window replacement. The more specialized training its staff has, and the longer it has been active, the more likely it will deliver high-quality service.

Licensing and Credentials

In Virginia, a window contractor needs a state contracting license if they must pull permits for their work. Some jurisdictions require building permits for window replacement, while others like Fairfax, Arlington, and Prince William Counties do not.

Types of Windows Offered

There are many replacement window types you can choose from, and it's important to find a company that specializes in the ones you want. Search a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the materials that an installer uses. Each frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they mount use wood, fiberglass, metal, vinyl, or composite.

Customer Feedback

Perhaps the best way to vet window companies for your job is to find out what previous customers have said about them. Read customer reviews on sites such as Yelp, Google, and Trustpilot. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Ashburn

How much energy and money will I save by upgrading my windows?

In Ashburn specifically, most homeowners using efficient windows lower their carbon emissions by 380 pounds annually. That amounts to $350 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By installing new, more efficient windows, you can boost your home's energy efficiency and reduce your electricity bills.

Does window replacement involve pulling permits?

Whether you need a building permit to replace your windows varies on your local building codes and regulations. Some towns require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend you check with your local building department or contact a professional before beginning any window replacement work.

What repair services do window companies offer?

Window companies can perform a variety of repair jobs, ranging from broken glass and screens to faulty seals and mechanisms.
