While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

To effectively clean fine dust after construction, start by dusting high surfaces like ceiling fans, walls, and window sills, allowing the dust to settle. Then, use a vacuum with a HEPA filter on all surfaces, including furniture, carpets, and floors, making a second pass for thoroughness. Follow up by mopping hard surfaces with a damp mop to capture any lingering particles. It's also important to clean appliances, vacuum HVAC returns and supply vents, and replace the air filters. Properly ventilate the home to help clear out remaining dust, and avoid sweeping, which can spread the dust around.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.

Finding a quality professional window cleaning service is much like finding any other vetted home pro: You should ask friends and family members who you trust for recommendations for window washers in your area and check online ratings. Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.
