How To Choose a Window Company in Leesburg

An exceptional reputation is crucial when it comes to choosing a window provider. However, your chosen company should also suit your needs and understand your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with quality is vital. Choosing budget windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The final cost of your replacement windows will hinge on the particular sizes, materials, and styles you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. If you're unsure, a window specialist can help you figure out which options are best for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage 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

You'll also need to choose a window material. Homeowners often choose a material based on energy efficiency objectives, aesthetic preferences and the local climate. 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 warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

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

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit-related costs (if required), and labor. Be sure to discuss each of these factors with an estimator before committing to a window company.

Experience and Training

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

Licensing and Credentials

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

Types of Windows Offered

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

Finally, pay close attention to the framing materials that a window company uses. Each window frame material has a different energy efficiency level, price point and life span. A company will usually specify whether the windows they place use metal, composite, fiberglass, wood, or vinyl.

Customer Feedback

Perhaps the best way to screen window companies for your job is to read what previous customers have said about them. You can find customer reviews on websites like the BBB, Google, Yelp, and Trustpilot. 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 Leesburg

Why should I hire a professional to install or replace my windows?

Window replacement is a big investment that greatly impacts your home's comfort and energy performance. Hiring a professional window company to oversee your project ensures your windows will be properly installed, perform optimally, and be well-sealed. Companies also typically include a guarantee that covers required maintenance and most needed fixes.

Are there tax incentives for installing energy-efficient windows?

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Further, most state and some local authorities offer tax breaks of their own. We recommend consulting your local government for specific information about tax incentives available in your area.

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

If your window has a cracked pane, it might not be required to replace the window frame. In many cases, only the glass pane needs to be fixed unless the frame has also experienced significant damage. A professional can determine exactly what's necessary during an estimate visit.
