How To Choose a Window Company in Commack

It's essential to find a window company that aligns with your unique values, needs, and preferences. Consider the following points during your hunt:

Window Cost by Type

When it comes to upgrading your windows, value is paramount. Each window you purchase should offer top-notch durability at an affordable price point. Although high-quality windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The size, material, and style of your new windows play the largest role in determining your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's advisable to consult a vetted installer to determine your most suitable options.

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

Materials also help determine a window's cost. You might pick a material based on your desired look, the local climate, 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 $58-$1639
Composite $591-$1329
Fiberglass $97-$828
Vinyl $199-$1844
Wood $295-$1661

Other Window Replacement Costs

Ask each installer you're evaluating about warranty fees, labor costs, and permit fees. This will help you get a clear picture of the financial commitment involved in the project.

Experience and Training

Examine a company's website and contact a representative to learn more about its product and service offerings, pricing, and guarantees. Many companies also keep online photo galleries that highlight past projects.

Ensure that the company specializes in window replacement. The more dedicated instruction its staff has, and the longer it has been in operation, the more likely it will provide high-quality 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 creating their own licenses. For example, to put in windows in New York City, a company must secure a Home Improvement Contractor License by passing exams and ecological assessments.

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 focuses on installing the ones you want. Look on 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
Also, check the style of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include wood, aluminum, vinyl, composite and fiberglass.

Customer Feedback

Reading other customers' stories is an excellent way to screen potential window companies. Trustworthy sources for customer reviews include Google, Trustpilot, and Yelp 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 Commack

Why should I hire a professional to install or replace my windows?

Window replacement is an important expense that greatly impacts your home's livability and energy efficiency. Hiring a reputable window contractor to supervise your project ensures your windows will be properly installed, perform optimally, and be properly insulated. Companies also typically include a guarantee that covers required maintenance and most needed fixes.

Are there tax incentives for installing energy-efficient windows?

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 city or county government for more information on tax breaks specific to your area.

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

If you broke your window's glass, you may not need to replace the whole thing. Often, you can simply replace the shattered glass panel without having to replace the entire window unit. However, it's best to seek advice from a window repair expert to assess the most appropriate repair for your specific situation.
