How To Choose a Window Company in Buffalo

With Buffalo's robust local economy, you're sure to find a reliable window company that suits your values and preferences. As you contact companies, keep the following 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 economy windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The overall cost of your window replacement will rely on the specific materials, styles, and sizes 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 wise to consult a trusted installer to determine your most suitable options.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$219-$1343
Awning$316-$882
Bay$730-$5414
Custom$324-$902
Casement$252-$1464
Double-hung$117-$762
Egress$216-$540
Glass Block$43-$547
Picture$190-$1403
Single-hung$85-$1443
Skylight$108-$1303
Sliding$248-$1263
Storm$51-$356
Transom$264-$553

Window Material Cost

Window prices also vary based on material. Each option provides unique advantages depending on your climate and energy efficiency needs. Fiberglass and vinyl 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 TypesAverage Cost
Aluminum$51-$1443
Composite$521-$1171
Fiberglass$85-$730
Vinyl$175-$1624
Wood$260-$1464

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit-related costs (if required), and labor. Be sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Speak with a company representative to learn more about its guarantees, public and private credentials, and experience. 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 hasn't stopped local governments from intervening and establishing their own licenses. For example, to install windows in New York City, a company must earn a Home Improvement Contractor License by passing exams and ecological assessments.

Types of Windows Offered

The kind of window you desire should influence your company choice. Not every contractor will necessarily be familiar with the window styles you want. A company website will reveal more about the kinds of windows it specializes in, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the materials that a company uses. Each frame material has a different energy efficiency level, price point and life span. A company will usually specify whether the windows they set up use fiberglass, composite, metal, wood, or vinyl.

Customer Feedback

Reading other customers' stories is an excellent way to screen window companies in your area. 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. 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 Buffalo

How could new windows help my energy efficiency?

Buffalo homeowners could save up to $370 annually by upgrading to efficient windows. They'll also lower their property's carbon dioxide emissions by 65 pounds per year.

According to the federal 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 retain heat in the wintertime, improving your comfort and furthering your dollar.

Does window replacement involve pulling permits?

Whether you need a building permit to replace your windows depends on your local building codes and regulations. Some areas require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend you check with your local building department or contact a professional before undertaking any window replacement work.

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

If you cracked your window's glass, you don't necessarily need to replace the whole thing. Often, you can simply swap out the shattered glass panel without having to remove the entire window frame. However, it's best to seek advice from a professional to figure out the right solution for your specific situation.
