How To Choose a Window Company in Allentown

With Allentown's large population, you're sure to find a reputable window company that matches your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, value is king. Each window you buy should provide optimal durability at a reasonable price point. Although top-of-the-line windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The age of your home, together with the sizes, styles, and materials of windows you opt for, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. An expert can help you with picking the options 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 Types Average Cost
Arched $222-$1362
Awning $321-$894
Bay $740-$5489
Custom $329-$914
Casement $256-$1484
Double-hung $119-$772
Egress $219-$548
Glass Block $43-$555
Picture $192-$1423
Single-hung $87-$1463
Skylight $109-$1321
Sliding $252-$1280
Storm $52-$361
Transom $268-$561

Window Material Cost

Window prices also vary based on material. Each option offers unique advantages depending on the local 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 in Allentown's strong storms, so they tend to cost more.

Window Types Average Cost
Aluminum $52-$1463
Composite $528-$1187
Fiberglass $87-$740
Vinyl $178-$1646
Wood $264-$1484

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit-related costs (if required), and labor. Ensure that you discuss each of these elements with a sales representative before committing to a window company.

Experience and Training

Choose a provider that focuses on window installation and repair, 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

While Pennsylvania window contractors aren't required to get a state license, they must still register with the attorney general's office and follow written contract requirements for residential jobs over $500 in value. Some cities, including Philadelphia, require licensure and have liability insurance standards.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's essential to find a company that specializes in the ones you want. Browse 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 an installer uses. Each frame material has a different life span, energy efficiency level and price point. A company will usually specify whether the windows they place use fiberglass, metal, wood, vinyl, or composite.

Customer Feedback

Perhaps the best way to screen window companies for your job is to see what previous customers have said about them. Read customer reviews on sites such as Trustpilot, Yelp, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Ask people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Allentown

How much energy and money will I save by upgrading my windows?

Allentown homeowners could potentially save $300 per year by upgrading to efficient windows. They'll also lower their property's carbon dioxide emissions by 290 pounds per year.

According to the national Department of Energy, as much as 33% 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, both protecting your comfort and saving you money.

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 financial incentives of their own. We recommend contacting your local tax authority for specific information about tax incentives available in your area.

Should I replace my windows a couple at a time, or is it more economical to replace them all at once?

To form a window replacement strategy, consider your finances, home improvement goals, and energy efficiency targets. A step-by-step replacement enables budget management and prioritize the windows that need the most attention, but you'll also notice lesser improvements in efficiency. A complete window replacement will be more expensive up front, but you'll see a more dramatic energy efficiency improvement.
