"Recommend Joslin & Co for window cleaning. Hands down the best not just for service but the great customer service as well. You can tell Nico takes great pride in his work with the care for the building and his customers! He is a really cool down to earth guy yet still professional and quick and efficient in his services! 10/10 in my book."

Window Cleaning FAQs, answered by experts

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.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

The easiest way to remove window decals is to soak the area in hot, soapy water. Let it sit for 15 minutes before scraping it with a plastic scraper or the edge of a credit card. You can also remove window decals with white vinegar, rubbing alcohol, or applying heat from a hairdryer or steam cleaner.

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.
