How To Choose a Window Company in Wilmington

An exceptional reputation is key when it comes to choosing a window replacement company. However, your chosen company should also suit your priorities and respect your vision. Think about the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with performance is crucial. Choosing economy windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The total cost of your window replacement will rely on the specific materials, styles, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're undecided, a window company can help you determine which options are best for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window TypesAverage Cost
Arched$207-$1272
Awning$299-$835
Bay$691-$5126
Custom$307-$854
Casement$239-$1386
Double-hung$111-$721
Egress$205-$511
Glass Block$41-$518
Picture$179-$1329
Single-hung$81-$1367
Skylight$102-$1234
Sliding$235-$1196
Storm$48-$337
Transom$250-$524

Window Material Cost

Materials also help determine a window's cost. You might select a material based on your desired look, your energy efficiency goals, and the local climate. For example, wood windows 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$48-$1367
Composite$493-$1108
Fiberglass$81-$691
Vinyl$166-$1537
Wood$246-$1386

Other Window Replacement Costs

Ask each company you're evaluating 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 talk to a representative to learn more about its product and service offerings, pricing, and guarantees. Many window companies also keep online portfolios that highlight past projects.

Ensure that the company focuses on window replacement. The more dedicated instruction its staff has, and the longer it has been active, the more likely it will deliver high-quality service.

Licensing and Credentials

Delaware has no requirement for window installers to carry a state license. However, local governments 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 need to pay a fee to the city based on their annual revenue.

Types of Windows Offered

No two window installers offer the same window styles and materials. Find one that's an expert in the type you want for your home.

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

Customer Feedback

One of the best ways to evaluate a company is to see what other customers have written about their experiences. Read customer reviews on sites such as Trustpilot, Google, and Yelp. 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 Wilmington

What are the benefits of hiring a window installer?

Window replacement is a big expense that greatly impacts your home's livability and energy performance. Hiring a professional window company to oversee your project ensures your windows will be the right size, perform efficiently, and be well-sealed. Companies also typically include a warranty that covers required maintenance and most future repairs.

What time of year should I replace my windows?

Window replacement can be done year-round. However, the installation process may be different based on the season. Costs are often less expensive in winter when demand is lower. Keep in mind, however, that this could overexpose your home to the elements. Speak with a licensed window professional to determine the best climate conditions for your replacement project.

What are some important metrics to know when I shop for replacement windows?

You can assess the quality of a window by looking at some crucial numbers, including the following:
  • Air leakage rating, which measures how tight a window's seal is
  • Condensation resistance, which measures how a window holds moisture
  • U-factor, which shows a window's temperature-insulating capability
  • Visible transmittance, which determines how much visible light passes through a window
  • Solar heat gain coefficient, which measures how much heat from sunlight can pass through the window
