How To Choose a Window Company in Quincy

An exceptional reputation is key when it comes to choosing a window company. However, your chosen company should also suit your needs and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with durability is crucial. Choosing budget windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The size, style, and material of your new windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's advisable to consult a trusted installer to decide on your ideal options.

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 $219-$1348
Awning $318-$885
Bay $732-$5434
Custom $326-$905
Casement $253-$1469
Double-hung $118-$764
Egress $217-$542
Glass Block $43-$549
Picture $190-$1409
Single-hung $86-$1449
Skylight $108-$1308
Sliding $249-$1268
Storm $51-$358
Transom $265-$555

Window Material Cost

Materials also help determine a window's cost. You might choose a material based on your energy efficiency goals, the local climate, and your desired look. For example, wood windows 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 Types Average Cost
Aluminum $51-$1449
Composite $523-$1175
Fiberglass $86-$732
Vinyl $176-$1630
Wood $261-$1469

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 factors with an estimator before committing to a window company.

Experience and Training

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

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

Licensing and Credentials

Illinois doesn't issue state contracting licenses to window installers, but towns in the Land of Lincoln might have their own requirements for companies to follow. In Chicago proper, window installers must have a Class D or E license and submit copies of their business filings for the public record. Outside the Windy City, licensing requirements are not uniform.

Types of Windows Offered

No two installers offer the same window types and materials. Find one that focuses on the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the style of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include vinyl, wood, composite, fiberglass and aluminum.

Customer Feedback

Reading other customers' stories is an excellent way to screen different window companies. Trustworthy sources for customer reviews include the BBB, Google, 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 Quincy

How could new windows help my energy efficiency?

In Quincy specifically, most homeowners using efficient windows reduce their carbon emissions by 640 pounds per year. That amounts to $330 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By investing in new, more efficient windows, you can improve your home's energy efficiency and lower your electricity bills.

What should I do if a window is molding or has rot?

Mold like to set in due to moisture issues or water damage. Luckily, you may not need to replace your windows to solve this annoying and unsightly issue. A window company can remove the rot, restore the affected area, and reestablish the tight seal your windows need to work at their healthiest.

How important are guarantees and extended support packages?

We strongly recommend choosing a window company that backs their work with a guarantee for your protection. These plans usually cover material flaws, manufacturer defects, and workmanship errors that appear after installation. Check the warranty terms with a window company before signing the contract.
