"In the past, I have cleaned my own windows. This is the first time I have used a professional window cleaner, and I was a little nervous about how the windows would turn out because Iâ  m pretty fussy. I am so pleased with Delâ  s Window Cleaning! They were easy to reach, responsive, punctual, professional, and they did a great job. Will definitely use them again. HIGHLY RECOMMEND."

Window Cleaning questions, answered by experts

Clean regularly and inspect seals for wear. Replace damaged parts promptly to maintain effectiveness.

Yes, many services include cleaning as part of the repair process. Confirm with your provider.

Yes, many professionals use biodegradable detergents and water-efficient cleaning techniques to minimize environmental impact.

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.

Because the built-in blinds are encased in glass, they should not get dusty. You might, however, find that your door’s window panes get dirty. If that is the case and you wish to clean your patio door’s glass, first remove any loose debris with a small vacuum or brush. Next, fill a bucket with warm water and some mild dish soap. Dip a clean rag into the bucket and wet the glass on your patio door. Dry the glass with a clean microfiber cloth.
