How To Choose a Window Company in St. Peters

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

Window Cost by Type

When you're shopping for replacement windows, it's essential to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Although high-quality replacement windows may come with a higher initial price tag, they often yield better long-term value due to their increased lifespan. The final cost of your replacement windows will depend on the specific materials, sizes, and styles you need. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's advisable to speak with a vetted window installer to decide on your ideal 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

Replacement window prices also vary based on material. Each option provides different benefits depending on the local climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

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 evaluating 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

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 installing efficient windows. They'll also decrease their property's carbon dioxide emissions by 760 pounds per year.

According to the federal Department of Energy, up to a third of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-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 window frame with mold indicates a moisture issue. You might not have to replace the entire window. Instead, a simple framing job could do. It's advisable to consult a window expert to ensure a proper seal.

What are some important metrics to know when I shop for replacement windows?

You can determine the quality of a window by examining some crucial numbers, including the following:
  • Air leakage rating, which shows how tight a window's seal is
  • Condensation resistance, which measures how a window holds moisture
  • U-factor, which shows a window's insulating capability
  • Visible transmittance, which measures how much visible light passes through a window
  • Solar heat gain coefficient, which evaluates how much heat from sunlight can pass through the window
