How To Choose a Window Company in Niagara Falls

An exceptional reputation is key when it comes to choosing a window provider. However, your chosen company should also align with your needs and appreciate your vision. Think about the following factors during your company search:

Window Cost by Type

When it comes to upgrading your windows, cost-effectiveness is king. Each window you purchase should offer top-notch durability at a fair price point. Although high-quality windows may come with a higher initial price tag, they often provide better long-term value due to their extended lifespan. The overall cost of your window replacement will rely on the specific styles, sizes, and materials you need. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. An expert can guide you through choosing the solutions that fit your requirements.

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

Window Types Average Cost
Arched $224-$1377
Awning $324-$904
Bay $748-$5551
Custom $333-$925
Casement $259-$1501
Double-hung $120-$781
Egress $222-$554
Glass Block $44-$561
Picture $194-$1439
Single-hung $88-$1480
Skylight $111-$1336
Sliding $254-$1295
Storm $52-$365
Transom $271-$567

Window Material Cost

Window prices also vary based on material. Each option offers different benefits depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window Types Average Cost
Aluminum $52-$1480
Composite $534-$1200
Fiberglass $88-$748
Vinyl $180-$1665
Wood $267-$1501

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, guarantees, and any other additional costs that your project may need.

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 guarantees, experience, and public and private credentials. Company websites often have photo galleries showcasing 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 taking charge and creating their own licenses. For example, to put in windows in New York City, a company must earn a Home Improvement Contractor License by passing exams and ecological assessments.

Types of Windows Offered

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

  • 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 composite, vinyl, aluminum, fiberglass and wood.

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Trustpilot, the BBB, and Google 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 Niagara Falls

What are the benefits of hiring a window installer?

By working with a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right supplies and training to do the job safely and accurately. You can also get fast, informed answers to your questions and customized guidance to make the most of your new windows

I've heard there are tax credits for energy-efficient windows. How much could I save?

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 speak with your local building department for more information on credits and incentives specific to your area.

What's different between a new construction window and a replacement window?

New construction windows are tailored for fresh builds and major renovation projects. Most, but not all, have a vinyl "nailing fin" that extends from the frame and secures the window to the house's sheathing. On the other hand, replacement windows (sometimes called "retrofit windows") don't have their own nailing fin. Instead, they're designed to use the existing sheaths.
