How To Choose a Window Company in Oakville

An exceptional reputation is key when it comes to choosing a window installer. However, your chosen company should also suit your priorities and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with value is crucial. Although top-of-the-line windows may cost more upfront, they often provide better long-term value due to their longer lifespan. The size, material, and style of your replacement windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can guide you through picking the products that fit your requirements.

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

Window TypesAverage Cost
Arched$236-$1451
Awning$342-$953
Bay$788-$5849
Custom$350-$974
Casement$273-$1581
Double-hung$127-$823
Egress$234-$584
Glass Block$46-$591
Picture$205-$1516
Single-hung$92-$1560
Skylight$116-$1408
Sliding$268-$1365
Storm$55-$385
Transom$285-$597

Window Material Cost

Replacement window prices also vary based on material. Each option offers unique advantages 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$55-$1560
Composite$563-$1265
Fiberglass$92-$788
Vinyl$189-$1754
Wood$281-$1581

Other Window Replacement Costs

Ask each company you're considering about labor costs, warranty fees, and permit fees. This will help you gain a complete understanding of the overall expenses involved in the project.

Experience and Training

Examine a company's website and chat with a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online galleries that present past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been in business, the more likely it will deliver excellent craftsmanship.

Licensing and Credentials

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

Types of Windows Offered

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

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

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, the BBB, and Trustpilot Talk to people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Oakville

How could new windows help my energy efficiency?

In Oakville specifically, most homeowners using efficient windows reduce their carbon emissions by 760 pounds per year. That amounts to $380 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By purchasing new, more efficient windows, you can improve your home's energy efficiency and reduce your electricity bills.

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

Mold like to set in due to moisture issues or water damage. Fortunately, you may not need to replace your windows to solve this annoying and unsightly issue. A window company can eliminate the rot or mold, restore the affected area, and reset the tight seal your windows need to work at their best.

How long does a window replacement job take?

The length of a window replacement project can vary greatly. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes around an hour per window. Keep in mind, larger windows or more complex installations may require additional time.
