COMFORT, LIGHT & BUDGET

Choose the glass for your home.

Compare the construction, then add your preference straight to your quote.

Double-pane

2 glass panes · 1 insulating space

A practical starting point when balancing the upfront cost with better insulation. Two panes enclose one insulating space.

Consider it for
A balanced window budget across several rooms.
Compare in the quote
The complete window’s U-factor, glass coating and frame.

Triple-pane

3 glass panes · 2 insulating spaces

An extra pane creates a second insulating space and can reduce heat transfer. Worth comparing for rooms where winter comfort is a priority.

Consider it for
Colder rooms and projects prioritizing insulation.
Compare in the quote
The tested U-factor compared with the added price.

Pane count is only part of performance. A lower whole-window U-factor means less heat transfer; Low-E coatings, gas fill, frame construction and installation also matter. Solar heat gain describes how much of the sun’s heat comes through. Window ratings explained by Natural Resources Canada (opens in a new tab)↗

THE FINISHING TOUCHES

Make it yours.

Keep the view simple or add a grille pattern. Tell us the frame colour you have in mind, inside and out, and we’ll match it to the range for your windows.

Preferences guide your quote; finishes and grille layouts depend on the selected window.

WINDOW ENLARGEMENT · WOODBRIDGE

Your new windows do not have to repeat the old layout.

This home had six small arched windows upstairs. We changed the brick openings and installed three larger rectangular windows, then finished the new sills, custom aluminum and window perimeters.

SUPPLY, INSTALLATION & FINISHING

From your choices
to finished windows.

Work directly with Maxim, Strataline’s owner, to connect your product choices, ordering and installation.

  1. Choose & measure

    Send your shortlist. We discuss the rooms, check the existing frames and measure on site before ordering.

  2. Set the scope

    Receive a written proposal with the windows, installation method, finishing, price and timing.

  3. Order & install

    Once you approve the proposal, we coordinate ordering and installation around the confirmed products.

  4. Finish & clean up

    We complete the specified trim and surrounding work, then the removal, disposal and cleanup in your scope.

Retrofit or full-frame?

Retrofit replacement

The existing frame stays when it is sound and suitable. A new unit fits within it, which can reduce the visible glass area.

Full-frame replacement

The old frame comes out too. This exposes the opening for repairs, insulation and new interior or exterior finishing.

We check the frame condition and finish details on site to choose the right approach.

A CLEAR PRICE FOR THE COMPLETE JOB

What’s included
in your window quote?

Size, style, glass and finish affect the product price. The frame condition, access and surrounding finish work affect installation cost.

Your proposal breaks out the windows and the work around them, with additional repairs or changes identified separately.

Support after installation

We correct defects caused by our workmanship. Coverage applies to the original client while they own the property, subject to the manufacturer’s warranty period for supplied products. If no meaningful product warranty applies, workmanship coverage continues through that ownership.

For windows we supply, Strataline documents and coordinates product warranty claims and covers removal and reinstallation labour for a valid claim. The manufacturer’s written terms govern product replacement. Normal wear, accidental damage and unrelated building movement are excluded; coverage ends on sale or repair or alteration by another contractor.

    FAQ

    A few more answers

    Can I compare double-pane and triple-pane in my quote?

    Yes. Choose “Compare both in my quote” to include both glass packages with your selected styles. We compare the price and whole-window specifications for your openings, including heat transfer and glass coatings. You can keep “Help me choose” selected if you have no preference yet.

    Do I have to order windows for the whole house?

    No. Start with one window, a few priority rooms or the whole home. Tell us which windows will stay so we can coordinate the frame colour, proportions and trim. If you plan to replace more later, we record your choices; future product availability can change.

    Can one request include several different window styles?

    Yes. Add as many styles as you like to your shortlist and give an approximate total window count. You do not need a quantity for each style. A fixed window can frame a view while casements, sliders or hung windows provide ventilation in other rooms.

    Why does the catalogue request a quote instead of showing a checkout price?

    Each opening has its own dimensions and installation needs. Size, operating style, glass, colour and finish work all affect cost, along with access and any damage around the frame. We price the selected windows and installation together, with additional repairs identified separately, before you approve an order.

    Do I need exact dimensions to send my selections?

    No. Your preferred styles, approximate count and town or postal code are enough to start. Photos and rough measurements are optional. Strataline takes the final measurements on site before ordering and checks the frame condition, opening direction and surrounding finishes so the new windows fit the actual openings.

    What is included in a supply-and-install window proposal?

    We list the window styles, sizes, glass and finishes, then set out the installation method, removal and disposal, sealing and insulation. The quote also specifies interior casing, exterior finishing and cleanup. Drywall, painting or other extra work is identified separately so you know how each opening will be finished.

    When can I choose an installation date for my new windows?

    Include your preferred timing in the request. After measuring and selecting the windows, we check current production and delivery times and plan the installation with you. Glass, colours and custom configurations can change the lead time. We confirm the expected schedule before the order is placed.

    How does Strataline support my windows after installation?

    We correct defects caused by our installation. Workmanship coverage applies to the original client during their ownership, subject to the manufacturer-warranty period for supplied products. Where no meaningful product warranty exists, the ownership period applies. Coverage ends on sale or another contractor’s repair or alteration; normal wear, misuse and unrelated damage are excluded.

    For windows we supply, we inspect concerns, document the issue and coordinate manufacturer claims, including removal and reinstallation labour for a valid supplied-product warranty claim. The manufacturer’s written terms govern replacement products and claim approval.
