How To Choose a Window Company in Newtown

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

Window Cost by Type

Replacing your windows is a major purchase, so balancing cost with quality is crucial. Although top-of-the-line replacement windows may be more expensive to buy, they often yield better long-term value due to their longer lifespan. The final cost of your window replacement will depend on the particular sizes, styles, and materials you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's wise to consult a vetted window installer to determine your ideal options.

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$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

Replacement window prices also vary based on material. Each option offers different benefits 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$56-$1,574
Composite$568-$1,276
Fiberglass$94-$796
Vinyl$191-$1,770
Wood$284-$1,595

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 take into account the cost of labor, guarantees, and any other supplemental fees that your project may need.

Experience and Training

Select a business that focuses on window replacement and installation, and look for this information on its website:

  • How long it's been in business
  • Photo galleries of projects its crews completed
  • Private credentials attesting to its workmanship
The more experience a company has, the better its service and 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

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

Finally, pay close attention to the materials that a window company uses. Each window frame material has a different price point, energy efficiency level and life span. A company will usually specify whether the windows they set up use vinyl, composite, metal, wood, or fiberglass.

Customer Feedback

One of the best ways to evaluate a company is to read what other customers have written about their experiences. You can find customer reviews on websites like Google, Yelp, Trustpilot, and the BBB. Ask people you know who have used the company you're evaluating, and ask a representative for professional references.
