How To Choose a Window Company in Southampton

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

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. Choosing budget windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The material, style, and size 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. An expert can help you with choosing the options that fit your needs.

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
Glass Block$49-$621

Window Material Cost

You'll also need to choose a window material. Homeowners usually base their decision 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 total cost for new windows will also include warranty fees (if applicable), permit-related costs (if required), and labor. Be sure to discuss each of these aspects with an estimator before committing to a window company.

Experience and Training

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

Licensing and Credentials

New York's state government doesn't issue contracting licenses for window installers, but this doesn't stop local governments from stepping in and setting up their own licenses. For example, to place windows in New York City, a company must obtain a Home Improvement Contractor License by passing exams and ecological assessments.

Types of Windows Offered

The type of window you want should influence your company choice. Not every contractor will necessarily be familiar with the window brand you want. A company website will show more about the kinds of windows it deals with, such as:

  • 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 installer if it offers the frame material you want, such as aluminum, wood, composite, vinyl, or fiberglass.

Customer Feedback

Reading other customers' stories is an interesting way to screen different window companies. Trustworthy sources for customer reviews include Google, Trustpilot, and Yelp Talk to people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Southampton

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

In Southampton specifically, most homeowners using efficient windows cut their carbon emissions by 310 pounds annually. This means they save $220 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 enhance your home's energy efficiency and minimize your electricity bills.

Does window replacement involve pulling permits?

The answer to this question will depend on your local building codes and regulations. Some communities require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend checking with your local building department or contact a professional before proceeding with any window replacement work.

Can I replace just my windows' glass and not their frames?

If you broke your window's glass, you might not need to replace the whole thing. In many cases, you can simply swap out the damaged glass panel without having to remove the entire window frame. However, it's best to seek advice from a professional to figure out the best course of action for your specific situation.
