How To Choose a Window Company in Freeport

Each window company has varying offerings and approaches. To streamline the company search, keep these factors in mind:

Window Cost by Type

When it comes to window replacement, value is most important. Each window you replace should offer optimal durability at an affordable price point. Although premium windows may come with a higher initial price tag, they often provide better long-term value due to their longer lifespan. The style, material, and size of your new windows are the most significant factors in your final cost. 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 guide you through picking the solutions that fit your requirements.

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$237-$1459
Awning$344-$958
Bay$792-$5879
Custom$352-$979
Casement$274-$1589
Double-hung$128-$827
Egress$235-$587
Glass Block$47-$594
Picture$206-$1524
Single-hung$93-$1567
Skylight$117-$1415
Sliding$270-$1371
Storm$55-$387
Transom$287-$601

Window Material Cost

You'll also need to pick a window material. Homeowners often make their selection by considering aesthetic preferences, energy efficiency objectives and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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 TypesAverage Cost
Aluminum$55-$1567
Composite$566-$1271
Fiberglass$93-$792
Vinyl$190-$1763
Wood$283-$1589

Other Window Replacement Costs

Ask each window installer you're considering about labor costs, warranty fees, and permit fees. This will help you get a better picture of the overall expenses involved in the project.

Experience and Training

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

  • How long it's been in business
  • Photo galleries of projects its crews completed
  • Privately-issued credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Illinois doesn't issue state contracting licenses to window installers, but municipalities 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 business disclosures for the public record. Beyond the Windy City, licensing requirements are more varied.

Types of Windows Offered

No two window contractors offer the same window styles and materials. Look for one that focuses on the type you want for your home.

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

Customer Feedback

Reading other customers' stories is one of the best ways to screen potential window companies. Read customer reviews on sites such as Trustpilot, Google, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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.

Frequently Asked Questions About Window Replacement in Freeport

What are the benefits of hiring a window installer?

Window replacement is a significant expense that greatly impacts your home's livability and energy efficiency. Hiring a reputable window contractor to supervise your project ensures your windows will fit correctly, perform optimally, and be properly sealed. Companies also typically include a warranty that covers required maintenance and most future repairs.

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 that involve structural changes or alterations to the window openings. Generally, it's advisable to check with your local building department or contact a professional before undertaking any window replacement work.

How can I fix a broken window screen?

It depends on the tear size and where it's located on your window. You can usually repair small tears yourself using a special kit. Some window providers will supply you with one when they replace your windows, or you can get one for $5–10 from a local hardware store. Larger tears, or those located at the edge of a window, usually need expert help.
