How To Choose a Window Company in Germantown

Each window provider has unique offerings and approaches. To simplify the company search, keep these factors in mind:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with durability is important. Choosing cheap windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The overall cost of your window replacement will depend on the particular sizes, styles, and materials you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's recommended to consult a vetted 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 $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 choose a window material. Homeowners frequently choose a material based on the local climate, aesthetic preferences and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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 Types Average Cost
Aluminum $54-$1533
Composite $553-$1244
Fiberglass $91-$775
Vinyl $186-$1725
Wood $276-$1555

Other Window Replacement Costs

Ask each contractor 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

The longer a window installer has been operating, the better its workmanship will likely be. Contact a company representative to learn more about its experience, public and private credentials, and guarantees. Company websites often have photo galleries showing off previous work technicians have done.

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 trade and business exam, submit business filings, verify insurance information, and show good financial standing.

Types of Windows Offered

No two businesses offer the same window types and materials. Look for one that specializes in the type you want for your home.

  • 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 company if it offers the frame material you want, such as aluminum, composite, vinyl, wood, or fiberglass.

Customer Feedback

One of the most surefire ways to screen a company is to check what other customers have written about their experiences. Trustworthy sources for customer reviews include Google, the BBB, and Yelp Ask people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Germantown

What are the benefits of hiring a window installer?

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

What is the maintenance schedule for an average window, and how long will it last?

Refer to your window warranty to determine how long your windows are meant to last. Most home windows can last about 15–20 years. Check your windows for damage, leaks, and poor performance to determine whether your windows should be updated.

Is it better to replace all my windows at once, or just a few at a time?

The answer to this question largely depends on your budget, how your windows are doing overall, and your long-term home improvement goals. Replacing all your windows at once can improve your home's insulation and increase your home's resale value, while installing a few windows at a time can protect your budget and directs your focus to the windows in the worst condition. Ultimately, it's important to evaluate the advantages and disadvantages and select the approach that best fits your needs.
