How To Choose a Window Company in Southington

Each window installer has specialized offerings and approaches. To streamline the company search, keep these factors in mind:

Window Cost by Type

When it comes to upgrading your windows, value is paramount. Each window you buy should deliver maximum durability at a reasonable price point. Although premium replacement windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The age of your home, in addition to the sizes, materials, and styles of windows you choose, can impact pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're unsure, a window company can help you determine which options are most suitable for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Glass Block$47-$600

Window Material Cost

You'll also need to select a window material. Homeowners usually choose a material based on energy efficiency objectives, aesthetic preferences and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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

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 assess the cost of labor, guarantees, and any other additional costs that your project may entail.

Experience and Training

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

  • The number of years it's been in business
  • Photo galleries of projects its crews completed
  • 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 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 houses. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

There are several replacement window types you can choose from, and it's essential to find a company that specializes in 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 vinyl, composite, fiberglass, aluminum and wood.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen different window replacement companies. 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. Talk to people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Southington

How could new windows help my energy efficiency?

In Southington specifically, most homeowners using efficient windows reduce their carbon emissions by 150 pounds yearly. This means they save $450 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By investing in new, more efficient windows, you can improve your home's energy efficiency and reduce your electricity bills.

What time of year should I replace my windows?

There is no "right" time to upgrade your windows, but some seasons might be better than others depending on company demand and the local climate. Southington experiences intense winters, so consider scheduling your installation for the early summer or late spring.

I broke my window's glass. Could I replace just the glass?

If you broke your window's glass, you may not need to replace the whole thing. Often, you can simply change the broken glass panel without having to replace the entire window unit. However, it's best to talk to a professional to figure out the best course of action for your specific situation.
