How To Choose a Window Company in Smithtown

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

Window Cost by Type

When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Although high-quality windows may be more expensive to buy, they often yield better long-term value due to their increased lifespan. The style, size, 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 custom-cut arch window in a master suite will cost more. If you're undecided, a window company can help you decide which options are ideal for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window Types Average Cost
Arched $248-$1525
Awning $359-$1001
Bay $828-$6147
Custom $368-$1024
Casement $286-$1661
Double-hung $133-$865
Egress $245-$613
Glass Block $49-$621
Picture $215-$1593
Single-hung $97-$1639
Skylight $122-$1479
Sliding $282-$1434
Storm $58-$405
Transom $300-$628

Window Material Cost

Window prices also vary based on material. Each option gives you different benefits depending on the local climate and energy efficiency needs. Vinyl and fiberglass 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 Types Average Cost
Aluminum $58-$1639
Composite $591-$1329
Fiberglass $97-$828
Vinyl $199-$1844
Wood $295-$1661

Other Window Replacement Costs

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

Experience and Training

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

  • The number of years it's been in business
  • Photo galleries of completed projects
  • Privately-issued certifications attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

New York's state government doesn't issue contracting licenses for window installers, but this doesn't stop local governments from taking charge and establishing their own licenses. For example, to put in windows in New York City, a company must obtain a Home Improvement Contractor License by passing exams and sustainability audits.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's important to find a company that is experienced with the ones you want. Check a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as aluminum, wood, vinyl, composite, or fiberglass.

Customer Feedback

Perhaps the best way to vet window companies for your job is to see what previous customers have said about them. Read customer reviews on sites such as Google, Trustpilot, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Smithtown

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

Smithtown homeowners could save up to $220 per year by upgrading to efficient windows. They'll also decrease their property's carbon dioxide emissions by 310 pounds per year.

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

What time of year should I replace my windows?

Window replacement can be performed year-round. However, the installation process may be different based on the season. Costs are often more affordable in winter when demand is reduced. Keep in mind, however, that this could overexpose your home to the elements. Speak with a licensed window professional to determine the best climate conditions for your replacement project.

My window screen tore. How should I fix it?

Most broken screens are effortless to fix. For small tears, some window installers might offer you a repair kit that use strong adhesive patches. If your installer doesn't include a kit, you can buy one for about $5–$10 at a home supply store.

You might need to change the screen for large tears or those along the edges of the window. A window company you trust can get the job done at a reasonable cost.
