"Work was excellent. The team arrived within the time window specified. They brought all the tools they needed for the job (including high extension ladder to reach 3rd story windows). My windows are now sparkling and the patio and garden paths have never been cleaner. They also cleaned the plexiglass roof over the patio."

"I tried Intestate because they had great reviews. He was running a little late but communicated to me to let me know what time he would be there. James was very efficient and fast. He also used special wash that repelled dust and debris. My windows look amazingly clean. It was inexpensive and professionally done. James was very pleasant to talk with too."

Window Cleaning FAQs, answered by experts

Suggesting regular dusting and spot cleaning to maintain freshness.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.

Cleaning your windows not only improves your home’s curb appeal—and, therefore, property value—but it also prolongs the life of your windows. Clean windows make a big difference from the outside, so if you’re selling your home or plan on selling, window washing is an affordable way to make your home stand out. Additionally, cleaning the tracks and moving components in your window can help them last longer, potentially saving you money over time on window replacement costs and repair.

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.
