Yes, you should clean your windows before selling your house. Clean windows enhance the overall appearance, letting in more natural light and making rooms look brighter and more inviting. They contribute to a positive first impression for potential buyers, signaling that the home is well-maintained. This simple step can increase curb appeal and potentially boost the property’s value. Dirty windows, on the other hand, can be a deterrent, suggesting neglect and raising concerns about other maintenance issues. Investing in professional window cleaning is a cost-effective way to make your home more attractive to buyers.
