How To Choose a Window Company in Beloit

Each window company has unique offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

When you're shopping for replacement windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap replacement windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The age of your home, as well as the styles, sizes, and materials of windows you choose, can influence pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's wise to speak with a vetted window installer to decide on your ideal 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$224-$1,373
Awning$324-$901
Bay$746-$5,532
Custom$332-$922
Casement$258-$1,496
Double-hung$120-$779
Egress$221-$552
Glass Block$44-$560
Picture$194-$1,434
Single-hung$88-$1,475
Skylight$111-$1,332
Sliding$254-$1,291
Storm$52-$365
Transom$270-$565

Window Material Cost

Window prices also vary based on material. Each option provides different benefits depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong in Beloit's strong storms, so they tend to cost more.

Window TypesAverage Cost
Aluminum$52-$1,475
Composite$533-$1,196
Fiberglass$88-$746
Vinyl$179-$1,659
Wood$266-$1,496

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit application fees, and labor. Be sure to discuss each of these aspects with an estimator before committing to a window company.

Experience and Training

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

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

Licensing and Credentials

Wisconsin construction professionals need a Dwelling Contractor Qualifier certification from the Department of Safety and Professional Services for most residential work, including window replacement. The only exceptions are if a project is less than $1,000 in value, or if your town doesn't require building permits for window work.

Wisconsin is among a handul of states that mandate continuing education for contractors. A representative must take at least 12 hours of training every other year to stay in good standing. The state actively promotes business and trade best practices.

Types of Windows Offered

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

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

Customer Feedback

One of the most surefire ways to evaluate a company is to read what other customers have said about their experiences. Trustworthy sources for customer reviews include Trustpilot, the BBB, and Google 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.
