"Jennifer was fantastic! She was great to work with from start to finish. We had a bedroom/bathroom that had been badly neglected by a tenant for 15 years (dirt, grime, smell, etc.). She spent a few hours beyond what was expected to get it the job done (shampooed carpet five separate times). It look now looks and smells beautiful! We are forever appreciative and plan to use her again in the future. I HIGHLY recommend her to anyone!!"

"These men were the most professional I have had working for me. They came on time and began work immediately. The owner had given me a list of what was going to be done and they followed the list exactly. Fumigated under the house first and later laid black plastic to cover the rock floor. Fixed the leak problem stains as the leak I took care of and dried out under the house a month earlier. They clean mold from all surfaces in the house and fumigated it. They fumigated the attic. 8 hours later when I returned home all was clean and mold free. RECOMEND them highly."

Window Cleaning FAQs, answered by experts

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.

Yes, WD-40 can remove stickers from glass thanks to its chemical properties that can break down adhesives. Be sure to wear protective gloves when handling WD-40. Spray the window or glass item, and let it sit for 10 minutes before scraping it with a plastic scraper or credit card.

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.

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.

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.
