How To Choose a Window Company in Ontario

With Ontario's large population, you're sure to find a reputable window replacement company that aligns with your values and preferences. As you contact companies, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, value is most important. Each window you purchase should offer maximum durability at an affordable price point. Although high-quality replacement windows may cost more upfront, they often yield better long-term value due to their longer lifespan. The size, style, and material of your new windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. A professional can help you with selecting the products that fit your needs.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$224-$1376
Awning$324-$903
Bay$747-$5545
Custom$332-$924
Casement$258-$1499
Double-hung$120-$780
Egress$221-$553
Glass Block$44-$561
Picture$194-$1437
Single-hung$87-$1478
Skylight$110-$1335
Sliding$254-$1293
Storm$52-$365
Transom$271-$566

Window Material Cost

You'll also need to select a window material. Homeowners often choose a material based on the local climate, aesthetic preferences and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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$52-$1478
Composite$534-$1199
Fiberglass$87-$747
Vinyl$179-$1663
Wood$267-$1499

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, guarantees, and any other additional costs that your project may require.

Experience and Training

Select a company that focuses on window installation and repair, and look for this information on its website:

  • How many years it's been operating
  • Photo galleries of completed projects
  • Privately-issued accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

A California window installer must be licensed as a Glazing Contractor, General Building Contractor and Window Coverings Contractor if it handles jobs valued at over $500. Each license has its own test and experience requirements. If a contractor is caught working without a license, they'll have to pay hefty penalties.

Types of Windows Offered

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

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

Customer Feedback

One of the most surefire ways to evaluate a company is to check what other customers have written about their experiences. You can find customer reviews on websites like Google, Yelp, Trustpilot, and the BBB. Talk to people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Ontario

What are the benefits of hiring a window installer?

Replacing your windows is a big investment that greatly impacts your home's livability and energy performance. Hiring a reputable window contractor to oversee your project ensures your windows will be the right size, perform efficiently, and be well-sealed. Companies also typically include a guarantee that covers required maintenance and most needed fixes.

Do I need a building permit to replace my home's windows?

Window replacement may involve securing permits, depending on your local building codes and regulations. Some towns mandate permits for window replacement projects in cases involving structural changes or alterations to the window openings. We recommend you check with your local building department or consult a professional before starting any window replacement work.

How important are guarantees and extended support packages?

We strongly recommend choosing a window company that backs their work with a guarantee for your protection. These plans usually cover material flaws, workmanship errors, and manufacturer defects for a short time after installation. Check the warranty details with a window company before signing a contract.
