How To Choose a Window Company in Buffalo

With Buffalo's robust local economy, you're sure to find a dependable replacement window company in line with your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

When you're shopping for replacement windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Although top-of-the-line windows may come with a higher initial price tag, they often yield better long-term value due to their longer lifespan. The overall cost of your replacement windows will hinge on the particular 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 installer can help you with choosing the products that fit your preferences.

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-$1,344
Awning$317-$883
Bay$730-$5,416
Custom$325-$903
Casement$253-$1,464
Double-hung$118-$762
Egress$217-$541
Glass Block$43-$548
Picture$190-$1,404
Single-hung$86-$1,444
Skylight$108-$1,304
Sliding$249-$1,264
Storm$51-$357
Transom$265-$554

Window Material Cost

Materials also help determine a window's cost. You might select a material based on your energy efficiency goals, your desired look, and the local climate. For example, windows made of wood 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$51-$1,444
Composite$522-$1,171
Fiberglass$86-$730
Vinyl$176-$1,625
Wood$261-$1,464

Other Window Replacement Costs

Ask each window installer you're considering about warranty fees, labor costs, and permit fees. This will help you understand the total costs involved in the project.

Experience and Training

Choose a provider that focuses on window replacement and installation, and look for this information on its website:

  • The number of years it's been in business
  • Photo galleries of completed projects
  • Official non-government accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 want should play a role in your company choice. Not every contractor will necessarily be familiar with the types you want. A company website will show more about the styles of windows it focuses on, such as:

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

Customer Feedback

One of the best ways to evaluate a company is to see what other customers have written about their experiences. You can find customer reviews on websites like the BBB, Trustpilot, Yelp, 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.
