Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Whether you’re a renter or a buyer, you should clean a house when moving out. For renters, it’s usually written in the lease that a house must be cleaned before it’s vacated. If you’re unsure how thoroughly to clean the place, check with the landlord beforehand; otherwise, you may not receive your deposit back. When selling a house, a contractual agreement is often made with the realtor that the house is swept and that all personal belongings are removed before the previous owners move out.

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

• Does your price include the inside and outside of the windows?

• Will you clean the tracks, rails, and other internal components?

• Are you fully insured?

• How many years of experience do you have?

• What kind of cleaning products do you use?

• Do you have any customer references?

• Do you provide any other services, like exterior power washing?

Cleaning your windows not only improves your home’s curb appeal—and, therefore, property value—but it also prolongs the life of your windows. Clean windows make a big difference from the outside, so if you’re selling your home or plan on selling, window washing is an affordable way to make your home stand out. Additionally, cleaning the tracks and moving components in your window can help them last longer, potentially saving you money over time on window replacement costs and repair.
