How To Choose a Window Company in Potomac

It's important to find a window replacement company that matches your individual values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with performance is important. Choosing cheap windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The age of your home, in addition to the sizes, styles, and materials of windows you select, can impact pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can help you with selecting the solutions that fit your requirements.

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

Window TypesAverage Cost
Arched$232-$1427
Awning$336-$937
Bay$775-$5751
Custom$345-$958
Casement$268-$1555
Double-hung$125-$809
Egress$230-$574
Glass Block$46-$581
Picture$201-$1491
Single-hung$91-$1533
Skylight$115-$1384
Sliding$264-$1342
Storm$54-$379
Transom$281-$587

Window Material Cost

You'll also need to pick a window material. Homeowners usually make their selection by considering the local climate, aesthetic preferences 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 TypesAverage Cost
Aluminum$54-$1533
Composite$553-$1244
Fiberglass$91-$775
Vinyl$186-$1725
Wood$276-$1555

Other Window Replacement Costs

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

Experience and Training

Select a company that focuses on window installation and repair, and look for this information on its website:

  • How long it's been serving the Potomac area
  • Photo galleries of completed projects
  • Private credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Window contractors and subcontractors in Maryland must carry a license from the state's Home Improvement Commission. Each applicant for a license must take a test on business and trade practices, submit business filings, verify surety bond information, and show financial responsibility.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's vital to find a company that has expertise with the ones you want. Look on a company's website and reviews for any of these types:

Also, check the type of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include wood, vinyl, fiberglass, aluminum and composite.

Customer Feedback

One of the easiest ways to screen a company is to read what other customers have written about their experiences. Trustworthy sources for customer reviews include Yelp, Trustpilot, 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 Potomac

How could new windows help my energy efficiency?

In Potomac specifically, most homeowners using efficient windows reduce their carbon emissions by 230 pounds yearly. That amounts to $290 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 upgrading to new, more efficient windows, you can boost your home's energy efficiency and lower your electricity bills.

What should I do if a window is molding or has rot?

Rot tend to set in due to moisture issues or water damage. Luckily, you might not need to replace your windows to solve this annoying and unsightly issue. An expert can eliminate the mold, restore the affected area, and reset the tight seal your windows need to work at their best.

How can I gauge the quality of a replacement window?

One of the first metrics you'll notice when looking at a replacement window is its U-factor. The lower this number, the better the window is at stopping extreme heat and cold from entering your home. Other numbers to consider include:
  • "visible transmittance," which indicates how much light can pass through the window
  • "solar heat gain coefficient," which tells you how much UV light the window absorbs and releases as heat
  • "Condensation resistance," which determines how well a window can resist moisture (the higher the number, the better)
  • "Air leakage," which measures how easy it is for air drafts to occur (the lower the number, the better)
