How To Choose a Window Company in Stratford

It's essential to find a window provider that matches your specific values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with quality is important. Choosing cheap windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The size, style, and material of your new windows have the greatest impact on your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. It's advisable to consult a trusted installer to figure out your ideal options.

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

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

Materials also help determine a window's cost. You might select a material based on your energy efficiency goals, the local climate, and your desired look. 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 TypesAverage Cost
Aluminum$55-$1573
Composite$568-$1276
Fiberglass$93-$795
Vinyl$191-$1769
Wood$284-$1595

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit application fees, and labor. Ensure that you discuss each of these factors with a sales representative before committing to a window company.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Contact a company representative to learn more about its public and private credentials, experience, and guarantees. Company websites often have photo galleries demonstrating 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 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

The kind of window you prefer should factor into your company choice. Not every contractor will necessarily be familiar with the types you want. A company website will provide more about the styles of windows it focuses on, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the style of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include wood, vinyl, fiberglass, composite and aluminum.

Customer Feedback

Perhaps the best way to vet window companies for your job is to check what previous customers have said about them. Trustworthy sources for customer reviews include Trustpilot, Google, 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 Stratford

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

In Stratford specifically, most homeowners using efficient windows reduce their carbon emissions by 150 pounds every year. That amounts to $440 of annual savings.

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 enhance your home's energy efficiency and lower your electricity bills.

What should I do if a window is molding or has rot?

A window frame with mold or rot is usually a moisture issue. Luckily, you may not have to replace the entire window. Instead, a simple framing job could do. It's best to consult a window expert to ensure a proper seal.

How long does a window replacement job take?

It could take up to 4–7 weeks to begin installation after the contractor orders your windows from the manufacturer. The installation itself usually takes around an hour per window. A larger window will take more time to get done, but a particularly experienced crew can complete the work in less time.
