How To Choose a Window Company in St. Peters

Trustworthiness is crucial when it comes to choosing a window replacement company. However, your chosen company should also align with your needs and understand your vision. Think about the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with quality is important. Choosing budget windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The size, style, and material of your replacement windows have the greatest impact on your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. It's recommended to consult a vetted window installer to determine your best options.

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

Window TypesAverage Cost
Arched$232-$1423
Awning$335-$935
Bay$773-$5738
Custom$344-$956
Casement$267-$1551
Double-hung$124-$807
Egress$229-$572
Glass Block$45-$580
Picture$201-$1487
Single-hung$90-$1530
Skylight$114-$1381
Sliding$263-$1338
Storm$54-$378
Transom$280-$586

Window Material Cost

Materials also help determine a window's cost. You might select a material based on your energy efficiency goals, the local climate, and your desired look. For example, wooden 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-$1530
Composite$552-$1241
Fiberglass$90-$773
Vinyl$186-$1721
Wood$276-$1551

Other Window Replacement Costs

Ask each window installer you're considering about labor costs, warranty fees, and permit fees. This will help you understand the financial commitment involved in the project.

Experience and Training

Peruse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and guarantees. Many window 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 business, the more likely it will provide top-notch service.

Licensing and Credentials

Missouri doesn't require window companies to get a state license. Instead, local authorities set their own credentialing standards. Check with your city government to see what regulations they have for contractors, and look for companies with reliable private accreditations in your own research. A few good places to start include certificates from the AWDI or Fenestration and Glazing Industry Alliance.

Types of Windows Offered

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

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

Customer Feedback

Reading other customers' stories is an excellent way to screen window companies in your area. You can find customer reviews on websites like Yelp, Google, Trustpilot, and the BBB. Speak with 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 St. Peters

How could new windows help my energy efficiency?

St. Peters homeowners could potentially save $380 each year by switching to efficient windows. They'll also decrease their property's carbon dioxide emissions by 760 pounds per year.

According to the federal 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 in during the wintertime, improving your comfort and furthering your dollar.

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

A molding or rotting window frame points to a moisture issue. You likely won't have to replace the entire window. Instead, a simple framing job could do. It's advisable to consult a specialist to ensure a proper seal.

How can I gauge the quality of a replacement window?

One of the first metrics you'll encounter when looking at a replacement window is its U-factor. The lower this number, the better the window is at blocking extreme cold and heat from entering your home. Other numbers to look at include:
  • "visible transmittance," which measures how much light enters through the window
  • "solar heat gain coefficient," which tells you how much UV light the window absorbs and releases as heat
  • "Condensation resistance," which determines how well a window can resist moisture (the higher the number, the better)
  • "Air leakage," which evaluates how easy it is for air drafts to develop (the lower the number, the better)
