Energy Star - Highly Efficient Windows

Energy Star certified windows are designed to be more energy efficient than traditional windows. In addition to saving money on energy bills, they can also help to reduce your home’s carbon footprint.

Energy Star certified windows help to keep your home cooler in the summer and warmer in the winter, making it more comfortable for you and your family.

Vinyl windows experts

Vinyl Windows Markham

Vinyl is a durable material that is not susceptible to warping or rotting like wood, and it requires little maintenance. They are also available in a variety of colours and styles to suit any home. Are you preparing to sell your property? Consider vinyl windows to increase the value of your home. These windows offer a great combination of beauty, durability, and energy efficiency, making them an excellent choice for home and property owners.

triple pane windows

Triple Glass Markham

Triple glass windows are a type of window that consists of three panes of glass. Argon is used instead of air in the internal cavity of the glass units. Argon is an odourless, inert, safe gas that is denser than air. As a result, triple glazed windows provide reduced inter-pane convection and improve thermal insulation efficiency.

Triple pane windows are also generally thicker than single- or double-paned windows, which makes them more resistant to breakage. So if you're noticing drafts in your home, consider triple glass windows as they offer a number of benefits, including improved energy efficiency, increased sound insulation, and enhanced security.

window colour options

Colour Options

When it comes to choosing vinyl windows, there are a wide variety of colours available on the market. White is the most popular and affordable colour choice for vinyl windows, as it provides a clean and classic look. However, other popular colour choices include beige, brown, and grey.

There are also a wide range of darker colours available, such as black and navy blue. These darker colours can provide a more dramatic look for your home.

easy maintenance windows

Easy Maintenance

When it comes to easy maintenance windows, vinyl windows are some of the easiest to care for. Unlike wood windows, they don't require painting or staining, and they're also resistant to rot, warping, and insect damage.

These windows are designed to be weather-tight, so they won't let in drafts or leaks. As a result, you can expect your vinyl windows to provide years of trouble-free service with minimal upkeep.

Replacing windows in Markham is easy, but it often requires getting a permit from the city's building department. Although there are certain minor replacements and repairs that don't need permits, consulting with an expert window contractor is recommended to make sure all requirements are met.

Replacement of your windows and doors may be indicated by several signs. Here are a few things to look out for:

  • Age: If your windows are over 15-20 years old, they may be nearing the end of their lifespan and may need to be replaced.

  • Drafts and air leaks: If you feel drafts or notice air leaks around your windows, this may indicate that the seals have worn out and need to be replaced.

  • Condensation: If you notice condensation between the panes of your windows, this may indicate that the seals have failed and the window needs to be replaced.

If you are experiencing any of these issues, it may be time to consider replacing your windows. Consulting with a professional window company can help you determine the best course of action and find the right replacement products for your home.
