"Rudy and his team were great! Quoted me price, some windows required additional work but kept the agreed upon price. Rudy and the team arrived right on time and finished exactly when they estimated. Very nice and respectful crew, always important with kids in the house. Windows look like new! Highly recommend!"

Window Cleaning questions, answered by experts

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.

Soot can be harder to remove compared to other types of stains given its acidic nature. It can also cause underlying paint to peel off during the cleaning process. If your soot issue is a result of smoke damage, it’s recommended you call a pro to help remove it versus doing it yourself.

Professionals use advanced, eco-friendly products that ensure effective yet safe cleaning.

Professionals use high-pressure steam cleaners, brushes, and specialized cleaning solutions for effective results.
