How To Choose a Window Company in Chelmsford

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

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 economy replacement windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The material, style, and size of your replacement windows are the most significant factors in your final cost. 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 recommended to speak with a reliable window installer to determine 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$254-$1,556
Awning$367-$1,022
Bay$845-$6,269
Custom$376-$1,045
Casement$293-$1,695
Double-hung$137-$882
Egress$251-$626
Glass Block$50-$634
Picture$220-$1,625
Single-hung$99-$1,672
Skylight$125-$1,509
Sliding$288-$1,463
Storm$59-$413
Transom$306-$641

Window Material Cost

Replacement window prices also vary based on material. Each option gives you unique advantages depending on your climate and energy efficiency needs. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$59-$1,672
Composite$604-$1,356
Fiberglass$99-$845
Vinyl$203-$1,881
Wood$302-$1,695

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit-related costs (if required), and labor. Be sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

The longer a window provider has been in business, the better its workmanship will likely be. Contact a company representative to learn more about its public and private credentials, experience, and guarantees. Company websites often have photo galleries showcasing previous work technicians have done.

Licensing and Credentials

Massachusetts window installers are considered general contractors and require a Construction Supervisor License (CSL) with a window classification. CSL applicants need to pass an open-book exam and demonstrate three years of work experience. Once a contractor has a CSL, it also needs to register with the Office of Consumer Affairs and Business Regulation as a "home improvement contractor."

Types of Windows Offered

The type of window you want should influence your company choice. Not every contractor will necessarily be familiar with the window styles you want. A company website will provide more about the styles of windows it focuses on, such as:

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

Customer Feedback

Reading other customers' stories is an excellent way to screen different window companies. You can find customer reviews on websites like Trustpilot, the BBB, Yelp, and Google. 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.
