How To Choose a Window Company in Potomac

It's important to find a window replacement company that matches your individual values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with performance is important. Choosing cheap windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The age of your home, in addition to the sizes, styles, and materials of windows you select, can impact pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can help you with selecting the solutions that fit your requirements.

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

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 pick a window material. Homeowners usually make their selection by considering the local climate, aesthetic preferences and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows 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 assess the cost of installation, warranties, and any other additional costs that your project may require.

Experience and Training

Peruse a company's website and talk to a representative to learn more about its product and service offerings, pricing, and guarantees. Many window companies also keep online galleries that showcase 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 deliver high-quality service.

Licensing and Credentials

Window specialists 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 paperwork, verify insurance information, and demonstrate good financial standing.

Types of Windows Offered

No two window installers offer the same window designs and materials. Find one that specializes in the type you want for your home.

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

Customer Feedback

Reading other customers' stories is one of the best ways to screen potential window companies. You can find customer reviews on websites like the BBB, Yelp, Google, and Trustpilot. 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.
