"Let me start off with how amazing these guys are! They have worked with me every step of the way with payments and are very patient with my lack of being able to pay because of certain circumstances that happened. I make payments when I can and they are very flexible with everything! And my house was so clean when we came back i was pleasantly surprised! Thank you again for your hard work!"

"I have been using them for 3 years for multiple projects and would not go to somebody else. They also built a cabin in the woods. It was built 10 miles from the road so it was like carrying all the stuff up the path. They also did the garage and remodeling of the house, mostly kitchen and a little bit of plumbing work in the bathroom. I am still using them and I would be using them for the next thing that will be coming up too."

Window Cleaning questions, answered by experts

Regular cleaning, non-abrasive cleaners, and scheduling professional services every few months help maintain clarity and shine.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

A professional cleaning service generally takes a few hours, typically between 2 to 4 hours, depending on the property's size and the severity of any stains. Keep in mind that wet cleaning methods will require additional drying time.

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.

You can use hot, soapy water, white vinegar, rubbing alcohol, window cleaner, nail polish remover, WD-40, and cooking oil to remove glass labels. You can also apply heat with a hair dryer or steam cleaner. Use a plastic scraper or credit card to remove the adhesive, as a razor blade can permanently scratch your glass.
