How To Choose a Window Company in Amherst

With Amherst's large population, you're sure to find a dependable window company that aligns with your values and preferences. As you reach out to companies, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with performance is vital. Choosing economy windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The material, style, and size of your new windows are the most significant factors in your final cost. 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 speak with a reliable installer to figure out your ideal options.

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

Window Types Average 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

You'll also need to choose a window material. Homeowners frequently base their decision on the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average 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 applicable warranty fees, permit application fees, and labor. Be 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 guarantees. Many companies also keep online portfolios that present past projects.

Ensure that the company focuses on window replacement. The more specific training its staff has, and the longer it has been in operation, the more likely it will deliver top-notch service.

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 environmental audits.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's important to find a company that is experienced with the ones you want. Check a company's website and reviews for any of these types:

  • 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 provider uses. Each frame material has a different price point, energy efficiency level and life span. A company will usually specify whether the windows they install use fiberglass, composite, metal, wood, or vinyl.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen different window replacement companies. You can find customer reviews on websites like Google, the BBB, Trustpilot, and Yelp. Ask people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Amherst

What are the benefits of hiring a window installer?

Window replacement is a significant investment that greatly impacts your home's livability and energy performance. Hiring a skilled window installer to oversee your project ensures your windows will fit correctly, operate effectively, and be properly insulated. Companies also typically include a guarantee that covers required maintenance and most needed fixes.

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

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Further, most state and some local authorities offer tax credits of their own. We recommend contacting your local government for specific information about tax incentives available in your area.

How important are guarantees and extended support packages?

Window companies often offer assurances for the work they do. Each typically addresses problems with workmanship and materials for a specified period of time. It's essential to check the specific terms of the guarantee with a window company before you sign the contract.
