How To Choose a Window Company in Norwalk

Dependability is crucial when it comes to choosing a window company. However, your chosen company should also suit your priorities and respect your vision. Keep in mind the following factors during your company search:

Window Cost by Type

When you're shopping for new windows, it's crucial to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Although top-of-the-line windows may be more expensive to buy, they often provide better long-term value due to their increased lifespan. The age of your home, in addition to the sizes, styles, and materials of windows you choose, can affect pricing. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're undecided, a window specialist 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 Types Average 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

Materials also help determine a window's cost. You might choose a material based on the local climate, your desired look, and your energy efficiency goals. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window Types Average Cost
Aluminum $55-$1573
Composite $568-$1276
Fiberglass $93-$795
Vinyl $191-$1769
Wood $284-$1595

Other Window Replacement Costs

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

Experience and Training

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

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 considered "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 companies offer the same window types and materials. Look for one that's an expert in the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the materials that a provider uses. Each frame material has a different price point, life span and energy efficiency level. A company will usually specify whether the windows they install use composite, fiberglass, metal, wood, or vinyl.

Customer Feedback

Perhaps the best way to vet window companies for your job is to read what previous customers have said about them. You can find customer reviews on websites like Trustpilot, Google, the BBB, and Yelp. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in Norwalk

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

In Norwalk specifically, most homeowners using efficient windows cut their carbon emissions by 150 pounds per year. This means they save $440 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 upgrading to new, more efficient windows, you can improve your home's energy efficiency and minimize your electricity bills.

I've heard there are tax credits for energy-efficient windows. How much could I save?

Ultimately, the tax incentives you can claim depend on the scope of your window replacement and where you are. You can claim 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 get in touch with your local utility for more information on financial benefits specific to your area.

Do window companies have guarantees or warranties for their work?

We strongly recommend choosing a window company that backs their work with a warranty for your protection. These policies usually cover workmanship errors, manufacturer defects, and material flaws for a year or two after installation. Check the warranty terms with a window company before hiring it.
