Are you a homeowner looking to update your windows and or install sliding patio doors but feel overwhelmed by the renovation process? Many homeowners, especially those new to renovations, can find the prospect of upgrading to brighter windows and new doors daunting. However, the process can be seamless and stress-free with the proper guidance and a professional team by your side. In this blog, we’ll walk you through what a seamless window and door upgrade looks like. This includes choosing the right products and the installation process, with a focus on Centennial Windows & Doors’ professionalism and quality.

What should you be thinking about?

You have many options when embarking on window and door upgrades.

Windows materials and types

The first step in any window and door upgrade is to decide the materials and types that best suit your needs and home style. Windows come in various materials, such as vinyl, wood, aluminum, and fibreglass, each with advantages and considerations.

For instance, vinyl windows are known for their energy efficiency and low maintenance, while wood windows offer a classic, timeless look. Choosing a suitable material depends on your budget, energy efficiency goals, and aesthetic preferences.

When it comes to window types, you’ll need to decide between options like single-hung, double-hung, casement, and sliding windows. The choice often depends on the room’s layout, your ventilation requirement, and the size of the opening. Double-checking the energy efficiency ratings, like the ENERGY STAR® label, can help you make an informed decision.

Doors materials and types

Front exterior, patio, and interior doors all serve different purposes and have distinct style considerations. Front exterior doors should provide security, insulation, and curb appeal. Consider materials such as steel, fibreglass, or wood; each have their own unique features.

Patio doors, like sliding patio doors, are all about creating a seamless connection between indoor and outdoor spaces. Depending on your preferences, French or sliding glass doors can be great options.


Now that you have a clear idea of the windows and doors you want, it’s time to plan the installation process. This is where the professionalism and expertise of the installation team become crucial.

At Centennial Windows & Doors, our installers work in groups of two—one on the outside and one on the inside. This approach ensures that the fit and function of your new windows and doors are perfect for your home’s exterior and interior.

We take pride in our attention to detail during installation, ensuring the windows and doors are fitted securely, operate smoothly, and provide the energy efficiency you expect. Plus, with our fully painted interior trim included with every installation, we add those finishing touches that make your upgrade genuinely seamless.

Questions and answers

Let’s address some common questions homeowners have about window and door upgrades.

Is it worth replacing windows and doors?

Windows and doors are an investment in your home that will last decades. Replacing your windows improves your comfort, reduces your energy bills, adds value to your home, and improves your experience of your home through better ventilation and natural light. Replacing your windows and doors makes even more sense when you factor in government grants and other incentives.

Should I replace my twenty-year-old windows?

Windows that are twenty or more years old are likely to need replacing. Seals can weaken and allow drafts and leaks. However, carefully inspecting your windows will determine whether they’re still in good condition.

How messy is the new window installation?

A professional installation, like the one Centennial Windows & Doors provides, minimizes mess and disruption. Drop cloths and protective measures are used to keep your home clean. Once the installation is complete, thorough clean-up is part of the service.

Do new windows get installed from the inside or outside?

Centennial installers work in teams, with one installer working from the outside and another from the inside. This approach allows for precise fitting and testing from both sides, ensuring a seamless installation.

How long does it take to replace windows and doors?

The duration of the installation depends on the number of windows and doors being replaced and their complexity. On average, a professional team can replace several windows and doors daily, minimizing disruption to your daily routine.

What to check after window installation?

After the installation is complete, take some time to inspect your new windows and doors. Ensure they open and close smoothly, latch securely, and provide a tight seal. If you notice any issues, contact your installation team promptly to address them.
