How To Choose a Window Company in Bethesda

Each window company has varying offerings and approaches. To streamline the company search, keep these factors in mind:

Window Cost by Type

When it comes to upgrading your windows, value is paramount. Each window you buy should offer optimal durability at an affordable price point. Choosing economy windows could actually raise your overall cost, due to their reduced lifespan and more intensive maintenance needs. The overall cost of your window replacement will hinge on the particular styles, sizes, and materials you need. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. An expert can guide you through choosing the options that fit your needs.

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 $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

Window prices also vary based on material. Each option provides unique advantages depending on your climate and energy-saving goals. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

Window Types Average Cost
Aluminum $54-$1533
Composite $553-$1244
Fiberglass $91-$775
Vinyl $186-$1725
Wood $276-$1555

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 assess the cost of labor, guarantees, and any other extra expenses that your project may require.

Experience and Training

Browse a company's website and talk to a representative to learn more about its product and service offerings, pricing, and warranties. Many companies also keep online portfolios 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 in operation, the more likely it will provide excellent craftsmanship.

Licensing and Credentials

Window contractors and subcontractors in Maryland must carry a license from the state's Home Improvement Commission. Each candidate for a license must pass a trade and business exam, submit legal filings, verify insurance information, and demonstrate financial responsibility.

Types of Windows Offered

There are several replacement window types you can choose from, and it's crucial to find a company that focuses on installing the ones you want. Look on 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
Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as aluminum, wood, composite, vinyl, or fiberglass.

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, the BBB, 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 Bethesda

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

Bethesda homeowners could potentially save $290 annually by upgrading to efficient windows. They'll also decrease their property's carbon dioxide emissions by 230 pounds per year.

According to the national Department of Energy, up to a third of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and in during the wintertime, both protecting your comfort and saving you money.

How can I fix a rotting or molding window frame?

Rot tend to set in due to moisture issues or water damage. Fortunately, you may not need to replace your windows to solve this troublesome and unsightly issue. A professional can remove the mold, restore the affected area, and reset the tight seal your windows need to operate at their healthiest.

Should I replace my windows a couple at a time, or is it more economical to replace them all at once?

The answer to this question is primarily influenced by your financial situation, how your windows are doing overall, and your long-term home improvement goals. A full-window replacement can offer better energy efficiency and add value to your home, while replacing your windows over time can be more budget-friendly and let you focus on the windows in the worst condition. Ultimately, you should consider the benefits and drawbacks and choose the option that aligns with your goals.
