"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

Use of harnesses and ladders ensures safe roof access.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

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.

Solar screens are low-maintenance but benefit from occasional cleaning with mild soap and water. Avoid using harsh chemicals or pressure washing, as these can damage the mesh. Inspect screens annually for tears or loose frames to maintain performance. In dusty or coastal areas, more frequent cleaning may be necessary to prevent buildup.
