How To Choose a Window Company in St. Charles

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

Window Cost by Type

When you're shopping for new windows, it's crucial 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 replacement windows may come with a higher initial price tag, they often provide better long-term value due to their longer lifespan. The age of your home, together with the materials, styles, and sizes of windows you opt for, can impact pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. A professional can guide you through picking the products that fit your requirements.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$232-$1,424
Awning$336-$935
Bay$774-$5,739
Custom$344-$957
Casement$268-$1,552
Double-hung$125-$808
Egress$230-$573
Glass Block$46-$581
Picture$202-$1,488
Single-hung$91-$1,530
Skylight$115-$1,382
Sliding$264-$1,339
Storm$54-$378
Transom$281-$587

Window Material Cost

Materials also help determine a window's cost. You might pick 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 TypesAverage Cost
Aluminum$54-$1,530
Composite$553-$1,241
Fiberglass$91-$774
Vinyl$186-$1,722
Wood$276-$1,552

Other Window Replacement Costs

Ask each window installer you're evaluating about warranty fees, labor costs, and permit fees. This will help you gain a complete understanding of the total costs involved in the project.

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Speak with a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often have photo galleries where you can see previous work technicians have done.

Licensing and Credentials

Missouri doesn't require window companies to get a state license. Instead, counties and cities set their own credentialing standards. Speak to your city hall to see what rules they have for window installers, and look for businesses with trusted private accreditations in your own research. A few good places to start include credentials from the AWDI or FGIA.

Types of Windows Offered

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

Finally, pay close attention to the framing materials that a provider uses. Each window frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they mount use composite, wood, fiberglass, metal, or vinyl.

Customer Feedback

Perhaps the best way to screen window companies for your job is to see what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, the BBB, and Google Ask people you know who have used the company you're interested in, and ask a representative for professional references.
