How To Choose a Window Company in Rockville

Reliability is key when it comes to choosing a window company. However, your chosen company should also suit your needs and respect your vision. Consider the following factors during your company search:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with durability is important. Choosing economy replacement windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The overall cost of your window replacement will rely on the specific materials, styles, and sizes you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. If you're unsure, a window company can help you determine which options are ideal for your home.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$233-$1,428
Awning$337-$937
Bay$776-$5,753
Custom$345-$959
Casement$268-$1,555
Double-hung$125-$810
Egress$230-$574
Glass Block$46-$582
Picture$202-$1,491
Single-hung$91-$1,534
Skylight$115-$1,385
Sliding$264-$1,342
Storm$55-$379
Transom$281-$588

Window Material Cost

You'll also need to select a window material. Homeowners often choose a material based on energy efficiency objectives, the local climate and aesthetic preferences. 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 TypesAverage Cost
Aluminum$55-$1,534
Composite$554-$1,244
Fiberglass$91-$776
Vinyl$187-$1,726
Wood$277-$1,555

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 installation, guarantees, and any other extra expenses that your project may entail.

Experience and Training

The longer a window provider has been in business, 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 contractors and subcontractors in Maryland must carry a license from the state's Home Improvement Commission. Each candidate for a license must take a test on business and trade practices, submit business filings, verify insurance information, and prove good financial standing.

Types of Windows Offered

The type of window you want should play a role in your company choice. Not every installation crew will necessarily be familiar with the window brand you want. A company website will show more about the kinds of windows it works with, such as:

Equally important to your desired windows' shape is their framing. Ask your window installer if it offers the frame material you want, such as wood, composite, fiberglass, aluminum, or vinyl.

Customer Feedback

One of the most surefire ways to evaluate a company is to read what other customers have written about their experiences. Trustworthy sources for customer reviews include Google, the BBB, and Yelp Talk to people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.
