Make the change where it matters
Start with the windows you keep working around.
If a window sticks every morning or a room feels draughty, it can change how you use your home. Tell us which windows are bothering you and what you’d like to improve.
The Everyday Difference
Warmth, quiet, and rooms you want to spend time in.
Replacing aged windows is not just about glass and frames—it is about reclaiming the coldest corner of the living room, eliminating morning condensation, and enjoying peaceful quiet inside your home throughout the Canadian seasons.
Draft-Free Living:Tight compression seals prevent cold drafts along floors and seating areas.
Natural Light & Views:Slimmer modern frame profiles allow up to 15% more daylight into your daily rooms.
Acoustic Calm:Modern insulated double or triple glazing softens street noise and neighbourhood sounds.
Choose for the way you use your home
Think about how you want your windows to open, how you clean them and the look you want inside and out. These everyday details belong in the conversation alongside product specifications.
Make comfort part of the brief
Let us know where you notice draughts or difficult operation. The right next step depends on the condition of the window and its opening. We’ll discuss what needs to be assessed before replacement options are agreed.
Architectural Window Styles
Common styles for Canadian residential homes
Each style serves a purpose—from maximum ventilation to expansive landscape views:
Casement
Hinged at the side and crank open outward. Offers the tightest compression seal against wind and drafts.
Double-Hung
Both sashes slide vertically. Classic Canadian heritage look with tilt-in sashes for easy cleaning from inside.
Picture & Fixed
Non-opening units designed for maximum daylight, wide unobstructed views, and peak thermal insulation.
Awning
Hinged at top and open outward from bottom. Allows fresh airflow into the home even during rain showers.
Opening & Frame Assessment
Every window opening has its own story.
Whether your current windows are vinyl, wood, or aluminum, replacement requires checking the condition of the surrounding opening, casing, and insulation.
We discuss your specific opening dimensions, preferred hardware finishes, and whether full-frame replacement or retrofit inserts fit your structure best.
Clear, Step-by-Step Process
From your first idea to an agreed window project.
We make replacing your home windows straightforward and transparent, with no surprises or high-pressure tactics.

Clear Answers Before You Decide
What to know before you request a quote.
Who will carry out my window replacement?
Inatank Marketing Inc. provides the service under the GiantCrate name and engages specialists for its projects. Your written agreement will identify the work and responsibilities before installation is scheduled.
Can I replace just a few windows?
Tell us which windows you have in mind. We’ll discuss a targeted replacement or a larger project, subject to the scope and availability we confirm with you.
How much will my replacement cost?
The price depends on the windows, the condition of the openings and the work involved. Start with your project details. We’ll explain what is needed to prepare a quote, including any assessment cost, before you agree to that step.
Do you work in my area?
Enter your city or town and province or territory. We’ll confirm whether we can take on your project there before arranging an assessment or work.
When could the work start?
Timing depends on the agreed scope, product availability and scheduling. We’ll discuss those details with you and confirm the arrangements before work is booked.
What about warranties?
Your written proposal will identify the products and work included, along with any applicable product and workmanship warranty terms. Ask us to explain the coverage before you accept the proposal.
Will new windows fix every draught or condensation issue?
The cause needs to be understood first. Indoor humidity, seals, frames and installation can all affect what you notice. Tell us what is happening so the need for an assessment can be discussed. We do not diagnose your home through this form or promise a particular energy saving.
Who can see my request?
Our authorized team handles your request. Specialists working on our behalf may receive information needed for their role in your project. Hosting and email providers also process information to operate the website. We do not sell your request to other companies. Read our Privacy Policy.
Does submitting the form commit me to anything?
It asks our team to contact you about your project. An assessment, price and installation are agreed separately. You can ask us to stop following up by emailing [email protected].
