Three Approaches To Window Replacement - Clera Windows + Doors

Eventually, all the windows in your home will need to be replaced. Depending on the age and overall condition of the home it may be sooner or it may be later, but even homes that are only a few years old now will require replacement windows at some point.

However, you don’t always need to do a full-scale window replacement in order to get the job done properly. Sometimes, you only need to address a portion of the overall system.

Factors to ConsiderBefore you make a choice on which approach you’re going to follow, you should consider a few important factors.

  • BudgetYou have to figure out how much you can afford before you decide what you’re going to get. Most reputable places have financing options, so look into all your options.
  • The Current ConditionThe condition of your current windows and your home will help point you in the right direction. There’s no need to replace elements that don’t need it, or to leave parts that shouldn’t be there.
  • Your Future GoalsAre you planning on staying in the home long-term? Is it going on the market in the near future? Answering questions like these will also help you decide which direction to go!


With sash-only window replacement, the existing frame stays in place, while new sashes are installed. A sash generally refers to a number of smaller panes that are held together with glazing bars. This helps create a larger glazed area. The number of panes depends on which era you’re recreating with your windows. Modern, Georgian and Victorian are all different, so a professional inspection is required.

Insert Windows

Insert windows require a little more than just the sash-only replacement, but you still get the leave the frame in place. These work well if the frame is in good condition, but your glass or sash are damaged. If you plan to attempt this installation yourself, measure your window frames carefully, so everything fits.

Full-Window Replacement

Replacing the entire window and frame is the most expensive option, but it will also give you the most aesthetic value and energy efficiency. Full-window replacement is often necessary in older homes or homes where the frames have started to rot from water damage or mold. You’ll also need a full-window replacement if you want windows that are a different size than the ones you have now.

If you’re unsure, it’s always best to get a professional evaluation before you decide. Call us at Clera if you need to know what your options are for window replacement!
