How To Choose a Window Company in Dover

An exceptional reputation is key when it comes to choosing a window company. However, your chosen company should also align with your needs and respect your vision. Keep in mind the following factors during your company search:

Window Cost by Type

When it comes to upgrading your windows, cost-effectiveness is king. Each window you replace should provide top-notch durability at a reasonable price point. Choosing cheap replacement windows could actually raise your overall cost, due to their reduced lifespan and more intensive maintenance needs. The age of your home, together with the materials, styles, and sizes of windows you opt for, can affect pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's advisable to consult a reliable window 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 TypesAverage Cost
Arched$207-$1,272
Awning$300-$836
Bay$691-$5,128
Custom$308-$855
Casement$239-$1,386
Double-hung$112-$722
Egress$205-$512
Glass Block$41-$519
Picture$180-$1,329
Single-hung$81-$1,367
Skylight$103-$1,234
Sliding$235-$1,196
Storm$49-$338
Transom$251-$524

Window Material Cost

Materials also help determine a window's cost. You might choose a material based on your energy efficiency goals, your desired look, and the local climate. For example, windows made of wood 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 TypesAverage Cost
Aluminum$49-$1,367
Composite$494-$1,109
Fiberglass$81-$691
Vinyl$166-$1,538
Wood$247-$1,386

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 labor, warranties, and any other additional costs that your project may entail.

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 window companies also keep online portfolios that showcase past projects.

Ensure that the company specializes in window replacement. The more dedicated instruction its staff has, and the longer it has been in operation, the more likely it will deliver high-quality workmanship.

Licensing and Credentials

Delaware has no requirement for window installers to carry a state license. However, cities can set their own licensing requirements—many of which are rather easy to fulfill. Professionals in Wilmington and Newark must register their businesses with the local government. Those in Dover must also register, but they'll be charged a fee to the city based on their annual revenue.

Types of Windows Offered

There are several replacement window types you can choose from, and it's essential to find a company that is experienced with the ones you want. Search a company's website and reviews for any of these types:

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

Customer Feedback

Perhaps the best way to screen window companies for your job is to read what previous customers have said about them. 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.
