"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 FAQs, answered by experts

Access to professional tools ensures streak-free finishes and safety in hard-to-reach areas.

Yes, with special treatments that help repel water spots and grime build-up.

Post-construction cleaning services typically include debris removal, dusting, vacuuming, wiping and sanitizing surfaces, window cleaning, and floor polishing. Depending on the scope, services may also extend to duct cleaning and general interior cleaning.

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.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.
