How To Choose a Window Company in Oakville

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

Window Cost by Type

When you're shopping for replacement windows, it's crucial to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing budget windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The style, size, 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 advisable to speak with a trusted window installer to determine 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$237-$1,452
Awning$342-$953
Bay$789-$5,851
Custom$351-$975
Casement$273-$1,582
Double-hung$127-$823
Egress$234-$584
Glass Block$47-$592
Picture$205-$1,517
Single-hung$93-$1,560
Skylight$117-$1,409
Sliding$269-$1,365
Storm$55-$386
Transom$286-$598

Window Material Cost

You'll also need to pick a window material. Homeowners frequently choose a material based on the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost
Aluminum$55-$1,560
Composite$563-$1,266
Fiberglass$93-$789
Vinyl$190-$1,755
Wood$282-$1,582

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 install use composite, metal, vinyl, fiberglass, or wood.

Customer Feedback

One of the simplest ways to vet a company is to check what other customers have said about their experiences. Trustworthy sources for customer reviews include Trustpilot, the BBB, and Yelp Talk to people you know who have used the company you're interested in, and ask a representative for professional references.
