Window replacement costs vary depending on the size and number of windows, window style, glass package and the requirements of the existing openings. The best way to get an accurate number is to have the windows measured and receive an estimate based on the specific products you’re considering.

Yes! Northline works with made-to-order windows and doors manufactured in Ontario. Your openings are measured before ordering, with different window styles, glass packages, colours and door configurations available depending on your project.

Both can be good options depending on your home and what you want from the replacement. Double-pane windows are a practical choice for many projects, while triple-pane windows add another layer to the glass package. We can help you compare the options for the windows you’re replacing.

Northline installs a wide range of replacement window styles, including casement, awning, sliding, single hung, double hung, fixed, picture, bay and bow windows. Different styles can also be combined depending on the opening, ventilation and appearance you want.

Absolutely! Northline installs front entrance doors, side entrance doors, patio doors and other exterior door configurations. Depending on the product, you can explore different colours, glass designs, sidelights and hardware to create a door that works with your home.

Yes. Northline provides egress window installation, including projects that involve creating or enlarging basement window openings. Because egress projects can involve more than simply replacing an existing window, we can look at the opening and what may be required for your project.

Not necessarily. You can replace the windows or doors that need attention first and complete the rest of the home later if that works better for your project. We can provide an estimate based on the specific openings you want to prioritize.

Northline offers a 20-year window warranty. The coverage applicable to your project can depend on the products being installed, so we can go through the relevant warranty information with you before your order is finalized.

Northline serves homeowners throughout Ottawa and a number of surrounding communities across Eastern Ontario and the Ottawa Valley.
