How To Choose a Window Company in Central Islip

Trustworthiness is important when it comes to choosing a window installer. However, your chosen company should also match your needs and respect your vision. Consider the following factors during your company search:

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 high-quality and durable window. Choosing economy windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The overall cost of your window replacement will rely on the particular styles, sizes, and materials you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's recommended to speak with a trusted window installer to decide on your ideal options.

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
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 select 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 TypesAverage Cost
Aluminum$58-$1639
Composite$591-$1329
Fiberglass$97-$828
Vinyl$199-$1844
Wood$295-$1661

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to assess the cost of installation, warranties, and any other extra expenses that your project may entail.

Experience and Training

The longer a window company has been operating, 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 keep photo galleries demonstrating 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 establishing their own licenses. For example, to install windows in New York City, a company must secure a Home Improvement Contractor License by passing exams and sustainability audits.

Types of Windows Offered

No two window companies offer the same window styles and materials. Look for one that specializes in the type you want for your home.

Finally, pay close attention to the materials that a window company uses. Each window frame material has a different energy efficiency level, price point and life span. A company will usually specify whether the windows they install use metal, fiberglass, composite, vinyl, or wood.

Customer Feedback

One of the best ways to vet a company is to read what other customers have written about their experiences. Read customer reviews on sites such as Yelp, Trustpilot, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Talk to people you know who have used the company you're interested in, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Central Islip

What are the benefits of hiring a window installer?

Replacing your windows is a significant investment that greatly impacts your home's comfort and energy performance. Hiring a professional window company to supervise your project ensures your windows will be the right size, operate effectively, and be properly sealed. Companies also typically include a warranty that takes care of required maintenance and most future repairs.

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 up to 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.

How can I fix a broken window screen?

It depends on the size of the tear and where it's located on your window. You can usually fix small tears yourself using a special kit. Some window companies will supply you with one when they set up your windows, or you can purchase one for $5–10 from a local hardware store. Bigger tears, or those located at the edge of a window, usually need expert help.
