Should I Replace All of My Windows at Once?

Window replacement is important, especially if your current ones are old and not very energy efficient. However, replacing the windows in your home is a big project and it can be expensive. Many homeowners are faced with the question of whether they should replace all their windows at once, replace them one at a time, or do just a few at a time.

First, understand that there is no one-size-fits-all answer. You’ll need to base your decision on a few factors, including:

  • The age and condition of your current windows
  • The impact of any existing damage to your windows
  • Your budget

That said, homeowners who can afford it should consider replacing all their windows at once, particularly if those windows are over 20 years old. Doing so can save money both now and in the long term, and it also decreases the hassle involved with window replacement.


Many window installers are happy to offer discounts on multiple window orders, particularly if you want to do your entire home. This can save you thousands of dollars compared to replacing your windows a few at a time.

You Want the Same Models

While installing new windows in phases can help reduce your upfront costs, it might mean mismatched windows. Manufacturers retire models regularly, so doing the replacement in stages might mean the original windows are no longer available, forcing you to go with a different model. 

You’re About to Sell

If your home’s windows are old or damaged and you’re thinking about putting the place on the market, replacing your windows all at one time is a smart idea. It immediately boosts curb appeal, while also offering potential buyers a reduction on their utilities (new windows can cut your utility costs by up to 15% per year).

You Want to Avoid Hassle

Replacing the windows in your home is a big job. Replacing half the windows in your home is also a big job, and doing half now and half later just means that you’ll have to deal with a large interruption to your routine more than once. Most companies can replace all of a home’s windows within just one to two days. 

Replacing your windows all at one time is a great idea if you can afford it. Most companies will offer a discount, you eliminate the hassle involved with repeating the process later, and you ensure your windows match. Rusco Windows and Doors can help you choose the right windows for your budget.
