How To Choose a Window Company in Norwalk

Dependability is crucial when it comes to choosing a window company. However, your chosen company should also suit your needs and understand your vision. Consider the following factors during your company search:

Window Cost by Type

When it comes to upgrading your windows, value is most important. Each window you replace should offer maximum durability at a reasonable price point. Choosing economy replacement windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The style, size, and material of your new windows play the largest role in determining your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. An installer can guide you through selecting the options that fit your needs.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$239-$1,464
Awning$345-$962
Bay$796-$5,901
Custom$354-$983
Casement$275-$1,595
Double-hung$129-$830
Egress$236-$589
Glass Block$47-$597
Picture$207-$1,530
Single-hung$94-$1,574
Skylight$118-$1,421
Sliding$271-$1,377
Storm$56-$389
Transom$288-$603

Window Material Cost

Window prices also vary based on material. Each option offers unique advantages depending on the local climate and energy efficiency needs. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$56-$1,574
Composite$568-$1,276
Fiberglass$94-$796
Vinyl$191-$1,770
Wood$284-$1,595

Other Window Replacement Costs

Ask each company you're evaluating about labor costs, warranty fees, and permit fees. This will help you understand 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 warranties. Many window companies also keep online photo galleries 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 business, the more likely it will deliver high-quality workmanship.

Licensing and Credentials

While Connecticut doesn't require contractors to carry licenses, they must still register with the state's Department of Consumer Protection (DCP), and there are still restrictions on what jobs they can perform. Most residential window installers are categorized as "minor contractors" and can only work on single and multi-family homes. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's important to find a company that focuses on installing the ones you want. Search a company's website and reviews for any of these types:

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, vinyl, wood, fiberglass and composite.

Customer Feedback

Perhaps the best way to vet window companies for your job is to read what previous customers have said about them. You can find customer reviews on websites like Trustpilot, Google, the BBB, and Yelp. 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.
