Blog entry > Builders grade windows vs premium grade windows

In a brand new house, probably not.

Builder grade windows look great to most new home buyers, they are clean, clear and bright. But fast forward 5-10 years, and you’ll begin to see a differnt story. Read on to find out why?

Builder grade windows

Builder grade windows and contractor windows are industry terms that refer to stripped-down no frills lower-quality windows. Builders and developers purchase these lower-end windows to trim costs, maximise profits and be more competitive. And wow! don’t they look great in a brand new house!!!

Many builders in the Ottawa and surrounding areas have used and still use builder grade windows for new home construction. These windows are typically made of standard-grade materials and components, and although builder grade windows may look great in new homes, they usually only meet the minimum energy-efficiency Energy Star standards. Builder grade windows usually start to fail at 5-10 years.

Characteristis of builder grade windows:

  • They lose their seals prematurely, often many windows will go at the same time
  • Hardware rusts and breaks down quicker
  • Windows become difficult to operate
  • New windows usually only meet minimum energy-efficiency standards
  • Glass may become less clear over time
  • Little or no interior UV protection that can damage or fade furniture
  • Installation is often done by the builder who may not be installing windows correctly
  • Plain Jane screening

Premium custom grade windows

Premium grade windows are the best windows that a window manufacturer has to offer, they typically come with a 20 to lifetime warranty and can be customised with glass and colour options that allow the buyer to configure a window to their aesthetic and energy-efficiency requirements. To keep an already complex building process under control, very few builders offer premium custom grade windows as an option.

Replace or repair? That’s a good question!!!

If you own a house with failing builder grade windows you really only have two solution options for fixing the problem.

  1. You can replace the glass and operational parts as needed on a seemingly never ending ongoing basis. Keep in mind, most replacement glass suppliers will only give you a prorated 1-3 year warranty.

  2. You can replace the entire window, frame, glass, hardware with up-to-date energy-efficiency that will save you money over time and eliminate your future window worries with a 20 to life warranty.

Don’t forget to do your homework!

Not all premium grade windows perform at the same Energy Star specifications - read more, be sure to do your homework.  Compare specifications and ask about the best options to meet your aesthetic, window durability and energy-saving requirements - read more.

Some local companies wrongly refer to their competitor’s products as builder grade windows. If you are thinking about purchasing or replacing the windows in your home, one of the best indicators that you are not buying builder’s grade windows is the warranty - if the warranty is over 20 years, they are more than likely “premium grade” not “builders grade” windows.
