How To Choose a Window Company in Gaithersburg

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

Window Cost by Type

When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing economy windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, together with the sizes, styles, and materials of windows you opt for, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. If you're undecided, a window specialist can help you decide which options are ideal for your home.

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

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

Materials also help determine a window's cost. You might choose a material based on your desired look, your energy efficiency goals, and the local climate. 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 $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 factor in the cost of labor, warranties, and any other additional costs that your project may require.

Experience and Training

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

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been active, the more likely it will provide excellent service.

Licensing and Credentials

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

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's vital to find a company that focuses on installing the ones you want. Check 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 framing 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 set up use metal, vinyl, wood, fiberglass, or composite.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen different window companies. Trustworthy sources for customer reviews include Google, Yelp, and Trustpilot 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 Gaithersburg

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

By working with an expert, you don't need to worry about measurement missteps or not having the right tools. A window installation team is well-equipped with the right supplies and skills to do the job safely and precisely. You can also get fast, informed answers to your questions and customized assistance to maximize your new windows' potential.

Does window replacement involve pulling permits?

Window replacement may require obtaining permits, based on your local building codes and regulations. Some cities mandate permits for window replacement projects if they involve structural changes or alterations to the window openings. We recommend you check with your local building department or consult a professional before starting any window replacement work.

Do window installers also work with blinds and coverings?

Maybe. Many installers work with both windows and blinds, so you can design a window covering solution that adds aesthetic appeal and boosts your new windows' performance. However, based on your location, blind work can require a different license that a company might not have. During your company search, inquire with each representative about blind installation. If a company does not offer it, they may delegate the task to a different company or recommend a retailer that can help you with blinds.
