How To Choose a Window Company in Wentzville

Trustworthiness is important when it comes to choosing a window company. However, your chosen company should also suit your priorities and understand your vision. Consider the following factors during your company search:

Window Cost by Type

When you're shopping for replacement windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The style, material, and size of your replacement windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. If you're undecided, a window company can help you figure out which options are most suitable for your home.

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

Window TypesAverage Cost
Arched$225-$1385
Awning$326-$909
Bay$752-$5582
Custom$334-$930
Casement$260-$1509
Double-hung$121-$785
Egress$223-$557
Glass Block$44-$564
Picture$196-$1447
Single-hung$88-$1488
Skylight$111-$1343
Sliding$256-$1302
Storm$52-$368
Transom$272-$570

Window Material Cost

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

Window TypesAverage Cost
Aluminum$52-$1488
Composite$537-$1207
Fiberglass$88-$752
Vinyl$181-$1674
Wood$268-$1509

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to take into account the cost of installation, warranties, and any other additional costs that your project may need.

Experience and Training

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

Licensing and Credentials

Missouri doesn't require window providers to get a state license. Instead, local authorities set their own licensing requirements. Consult with your local building department to see what rules they have for contractors, and look for businesses with reliable private accreditations in your own research. A few good places to start include credentials from the American Window and Door Institute or Fenestration and Glazing Industry Alliance.

Types of Windows Offered

No two businesses offer the same window types and materials. Find one that specializes in the type you want for your home.

Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as composite, aluminum, vinyl, wood, or fiberglass.

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 Google, the BBB, and Trustpilot 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 Wentzville

What are the benefits of hiring a window installer?

By working with a professional, you don't need to worry about measurement missteps or not having the right tools. A window installation crew is well-equipped with the right tools and training to do the job safely and accurately. You can also get fast, informed answers to your questions and personalized assistance to make the most of your new windows

How frequently should I upgrade or replace my windows?

Windows don't last forever, and most vinyl and wood models are designed to serve your home for 15–20 years. Over time, caulking and weatherstripping loosen, framing contracts and expands, and window coatings fade. These changes result in energy loss, condensation, air leaks, and other expensive problems necessitating repair or replacement.

What kinds of repairs can my window company perform?

Many window companies repair screens, mechanisms, frames, window seals, and glass
