"The 2 workers went above and beyond. Made a badly stained and mildewed awning look brand new. Keith also fixed 2 door screens that had been pushed out by my grandchildren and my dog by accident. I did not ask he just did it. And Mary came back in the house to look into a smudge in a window that I look out of all the time. No attitude, just happy to take care of it. Very pleasant to have around. Had no qualms over having them in my house. Ron, you have a great crew."

"I recently had New England Shine soft wash my entire house, gutters included, and I couldn’t be happier with the results. My home looks brand new. Every trace of grime, mildew, and buildup is gone. Beyond the incredible work, the owner made the whole experience a pleasure. He’s genuinely down to earth, easy to talk to, and clearly takes pride in doing the job right. He gave me a great price without ever cutting corners on quality, which is hard to find these days. I’m already planning to have him back in the next few months, and I’m especially looking forward to their deionized water window cleaning next, from everything I’ve heard, it leaves windows completely spot-free. If you’re looking for a soft washing company that’s professional, fairly priced, and run by someone who actually cares about their customers, New England Shine is it. Highly recommend!"

Window Cleaning FAQs, answered by experts

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.

Do not mix bleach with vinegar, ammonia, acidic liquids, or other cleaners or detergents as toxic fumes result from the chemical reaction. Mix bleach only with water to avoid dangerous chemical reactions. Even mixed with water to dilute it, bleach can still be harmful to your skin, eyes, and lungs.

Professional window cleaning services save time, improve visibility, and enhance the appearance of your home or business. They also help extend the lifespan of your windows by preventing the buildup of grime and hard water stains through comprehensive cleaning.

All of the things you use to help you get clean can leave your shower door looking dirty. Water can leave mineral deposits as well as unsightly spots when drops of water dry on the glass. Soap and shampoo can cause build-up and residue that leaves a layer of soap scum in your shower, which then attracts dirt. Mold and mildew can also contribute to dirty shower doors; these fast-growing organisms thrive in areas with poor air circulation, damp conditions, and residue from things like soap and shampoo.

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.
