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$238-$1464
Awning$345-$961
Bay$795-$5899
Custom$353-$983
Casement$275-$1595
Double-hung$128-$830
Egress$235-$589
Glass Block$47-$596
Picture$207-$1529
Single-hung$93-$1573
Skylight$117-$1420
Sliding$270-$1376
Storm$55-$388
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$55-$1573
Composite$568-$1276
Fiberglass$93-$795
Vinyl$191-$1769
Wood$284-$1595

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

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

  • How many years it's been operating
  • Photo galleries of completed projects
  • 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 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 residences. 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 specializes in the type you want for your home.

Finally, pay close attention to the materials that an installer 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 install use metal, composite, fiberglass, wood, or vinyl.

Customer Feedback

One of the greatest ways to vet a company is to read what other customers have written about their experiences. Read customer reviews on sites such as Yelp, Trustpilot, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Speak with people you know who have used the company you're interested in, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Newtown

How much energy and money will I save by upgrading my windows?

Newtown homeowners could save up to $440 per year by switching to efficient windows. They'll also lower their property's carbon dioxide emissions by 150 pounds per year.

According to the federal Department of Energy, up to a third of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and in during the wintertime, improving your comfort and furthering your dollar.

Are there tax incentives for installing energy-efficient windows?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and the community you live in. You can claim up to 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to speak with your local utility for more information on financial benefits specific to your area.

How important are guarantees and extended support packages?

We strongly recommend choosing a window company that backs their work with a warranty for your protection. These plans usually cover material flaws, manufacturer defects, and workmanship errors for a year or two after installation. Verify the warranty details with a window company before signing the contract.
