How To Choose a Window Company in Buffalo

With Buffalo's robust local economy, you're sure to find a reliable replacement window company that matches your values and preferences. As you gather estimates, keep the following factors in mind:

Window Cost by Type

When it comes to replacing your windows, value is most important. Each window you buy should offer top-notch durability at a reasonable price point. Choosing economy windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The overall cost of your replacement windows will hinge on the particular styles, materials, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. A window expert can help you with picking the products that fit your preferences.

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$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 gives you unique advantages depending on your climate and energy efficiency needs. Vinyl and fiberglass 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 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 new windows will also include warranty fees (if applicable), permit-related costs (if required), and labor. Make sure to discuss each of these elements with an estimator before committing to a window company.

Experience and Training

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

Ensure that the company specializes in window replacement. The more specific training its staff has, and the longer it has been active, the more likely it will deliver top-notch craftsmanship.

Licensing and Credentials

New York's state government doesn't issue contracting licenses for window installers, but this hasn't stopped local governments from taking charge and creating 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 ecological assessments.

Types of Windows Offered

The style of window you want should play a role in your company choice. Not every installer will necessarily be familiar with the window brand you want. A company website will reveal more about the kinds of windows it works with, such as:

Also, check the kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include wood, aluminum, composite, vinyl and fiberglass.

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.
