It’s a common question from homeowners: should we invest in a full set of replacement windows, or only replace the ones that are an obvious problem? The answer is up to you.
Before you decide to take on a window replacement project or hire some help, you need to land on its scope. This guide from Renewal by Andersen® of Seattle should help you decide when you need window replacement and how many windows you should replace at a time.

How Many Windows Need to Be Replaced?
If the rest of your windows are looking good, operating well, and suiting your home just fine, it probably makes more financial sense to deal with the few windows that need replacement.
If, however, you are leaning toward replacing more of them, it can often save you money in the long term to get it all done at once. It will cost more upfront than it would to replace just a few windows, but if you are dealing with energy inefficiency or constant repairs, a bulk replacement will cut down on costs over the years.
When Should You Replace All Your Windows at Once?
Professionals agree if you have the budget, customers are better served by replacing as many windows as they can at once. If the windows in your home are more than 20 years old and showing signs of wear, just start planning and budgeting for window replacement.
Signs You Need Window Replacement
- Draft. If you feel a breeze that wafts into the room even when the windows are closed, it’s a draft problem. Sometimes you’ll have light seeping in through the gaps in the casement windows frame.
- Troublesome Operation. If a task as simple as opening, closing, or locking a window gets daunting, then you have a problem. A stuck window can block your exit when you need it the most, so you’re better off having it replaced.
- Visible Damage. The most conspicuous signs of damage appear on the frame, particularly wooden frames which absorb water. This then leads to swelling and eventually rotting.
- Poor soundproofing. If you live in a busy neighborhood, soundproof windows preserve your peace and quiet. If you can hear the sound outside clearly, your bay windows aren’t properly sealed.
