How To Choose a Window Company in Greenwich

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

Window Cost by Type

When you're shopping for replacement windows, it's essential to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing budget replacement windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The style, size, and material of your replacement windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's recommended to consult a trusted 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$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

You'll also need to pick a window material. Homeowners often choose a material based on aesthetic preferences, energy efficiency objectives and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

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 factor in the cost of installation, warranties, and any other supplemental fees that your project may require.

Experience and Training

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

  • How long it's been in business
  • Photo galleries of completed projects
  • Private certifications 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 limitations 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

The kind of window you prefer should play a role in your company choice. Not every installation crew will necessarily be familiar with the window styles you want. A company website will tell more about the kinds of windows it specializes in, such as:

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

Customer Feedback

One of the greatest ways to screen a company is to read what other customers have said 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.
