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 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$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 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$54-$1533
Composite$553-$1244
Fiberglass$91-$775
Vinyl$186-$1725
Wood$276-$1555

Other Window Replacement Costs

Ask each contractor you're considering about warranty fees, labor costs, and permit fees. This will help you get a clear picture of the financial commitment involved in the project.

Experience and Training

Browse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online galleries that present past projects.

Ensure that the company focuses on window replacement. The more dedicated instruction its staff has, and the longer it has been in operation, the more likely it will provide top-notch craftsmanship.

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 legal filings, verify insurance information, and show good financial standing.

Types of Windows Offered

The type of window you prefer should play a role in your company choice. Not every installer will necessarily be familiar with the types you want. A company website will reveal more about the window types it works with, such as:

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

Customer Feedback

Reading other customers' stories is a surefire way to screen different window companies. Read customer reviews on sites such as Yelp, Google, and Trustpilot. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Rockville

How could new windows help my energy efficiency?

In Rockville specifically, most homeowners using efficient windows reduce their carbon emissions by 230 pounds every year. 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 purchasing new, more efficient windows, you can enhance your home's energy efficiency and reduce your electricity bills.

Does window replacement involve pulling permits?

Window replacement may involve securing permits, based on your local building codes and regulations. Some areas mandate permits for window replacement projects when they involve structural changes or alterations to the window openings. We recommend checking with your local building department or consult a professional before starting any window replacement work.

Do window companies have guarantees or warranties for their work?

We strongly recommend choosing a window company that backs their work with a warranty for your protection. These policies usually cover workmanship errors, manufacturer defects, and material flaws that appear after installation. Check the warranty terms with a window company before hiring it.
