There are several indicators that suggest you should replace your home windows.
One common sign is when the windows become difficult to open or close, indicating that the frames or sashes are warped or damaged. Another sign is condensation build-up on the inside of the windows, indicating that the seals have failed, and air is leaking through.
You may also notice drafts of cold air coming through the windows, which not only makes your home uncomfortable but also impacts your energy bills.
Additionally, visible damage, such as cracks or breaks, also suggest that it's a good idea to consider replacement options to improve energy efficiency, safety, and aesthetics.
