Why Quality Windows and Doors Matter

Investing in new high-performance windows and doors for your Mississauga home comes with many benefits:

  • Increased energy efficiency - New window and door technologies like double/triple glazing, low-E coatings, and insulated frames reduce heat loss and lower energy costs.
  • Added comfort - Drafts and temperature fluctuations are decreased, keeping your home comfortable in both winter and summer.
  • Noise reduction - Contemporary windows and doors block outside noise better, creating a quieter indoor space.
  • Security enhancements - New locking mechanisms and reinforced materials make windows and doors much more secure.
  • Improved aesthetics - Replacing old windows and doors enhances your home's curb appeal and gives it an updated, modern look.
  • Higher resale value - Upgrading can add approximately 7% to your home's value, providing a great return on investment.

Choosing the right window and door company is the key to realizing these benefits. The expertise of an experienced local company ensures the job is done right the first time.

Factors to Consider When Choosing a Company

With so many window and door replacement options in Mississauga, focus on these factors to choose the best company:

Experience and Reputation

An established company with years or decades of experience is ideal. They understand local climate conditions and building codes. Check online reviews and testimonials.

Quality of Products

Look for weather-resistant materials like vinyl, wood, or fiberglass. Ensure glazing and frames meet ENERGY STAR® requirements for your region.

Professional Consultation

The company should provide an onsite assessment, take precise measurements, and make product recommendations for each window and door.


Reputable companies offer at least 10 years on window/door materials and 1 year on labor. Lifetime warranties provide peace of mind.

Customer Service and Installation

A 5-star customer experience includes ongoing support, minimal disruption during installation, and clean-up after.


Get quotes from several companies and look for available financing options that work with your budget.

Doing research enables you to find the ideal balance of high-quality windows and products, professional service, and affordability when choosing new windows and doors in Mississauga.

Things to Avoid When Choosing a Window Company

While researching window replacement companies, keep an eye out for these red flags:

  • High-pressure sales tactics or no showrooms/samples to view products.
  • Vague information about window materials or energy efficiency ratings.
  • Lack of licensing, insurance, or ability to pull city work permits.
  • Not offering service guarantees or warranties on their work.
  • Quotes that seem unrealistically low for quality work.
  • Unwillingness to provide customer references or reviews.
  • No established track record serving your local area.
  • Requests for full payment upfront before ordering materials or beginning work.

A professional, trustworthy company will gladly provide all relevant information upfront and give you time to make decisions. Avoid sellers that seem predatory or dishonest.

Frequently Asked Questions

What are the most popular styles of windows in Mississauga?

The most popular window styles for Mississauga homes are double-hung, casement, and slider windows. Double-hung windows are classic and provide great ventilation. Casement windows are energy efficient and offer full views. Sliders are easy to open and close.

What types of window frames last longest?

Fiberglass and vinyl window frames have the greatest durability and require the least maintenance over time. Avoid lower-cost aluminum frames which can bend and warp.

Should I choose single, double, or triple-pane glass?

Double-pane insulated glass is recommended for the best energy efficiency in Mississauga’s climate. Triple-pane windows provide slightly more efficiency but are more expensive. Single pane should be avoided.

How much do new window installations cost?

In Mississauga, expect to pay $600 - $1,200 per window installed. Costs vary based on window size, materials, accessibility, and additional finishes. Get quotes from multiple window companies.

When is the best time to replace windows?

Late spring to early fall is an ideal time for window replacements in Mississauga before winter sets in. Avoid the coldest winter months if possible. Give yourself several months to choose a company and schedule the work.

Should I hire one company for both windows and doors?

Working with one company for your window and door projects allows better coordination and cost savings. Ensure they have expertise with both product types.
