Why Mildew Grows So Fast on Tennessee Homes in Summer
Middle Tennessee summers are hot and humid, which is exactly what mildew and algae want.
The shady side problem
North walls and areas under trees stay damp longer after rain and dew, so growth shows up there first.
Why soft washing works
Growth has roots in the surface. Pressure alone knocks off the top; a soft wash solution kills it so it takes longer to come back.
Slowing regrowth
Trimming branches back from the house and improving airflow help more than any cleaner.
What you can try yourself
- Spot-clean small areas with a siding cleaner and a soft brush.
- Rinse thoroughly and keep plants wet while you work.
What to avoid
- High pressure on vinyl or painted surfaces.
When to call a professional
Call a pro when growth covers whole walls or reaches the second story. See our house washing service.
What customers say
"I completed a quote sheet online for an estimate to pressure wash my house. First- Clean Pressure Washing responded quickly. Chris called me to discussed what service I need. He looked at my house on the Internet so he was able to see clearly the size of the house. I also added my driveway to the cleaning process. I was given a quote, verbally and written, which I signed on a DocuSign. They communicated with me via text and were right on time based on the schedule provided. They had a truck that had the solution in it for cleaning my house, which I was really happy about because they didn’t use my water. My driveway was really messy and they did a very good job on my house and driveway. I felt the quote was fair and competitive. They got all of the mildew off the house. It looks great so I shouldn’t have any problem with my HOA for a couple years. Thanks so much, Chris. I really appreciate the service you provided!!!"

"After I was blindsided by an HOA violation I quickly called 1st Class Pressure Washing. They were there the next day and cleaned the exterior of my house to perfection. I’m glad to know I’ll always have them on call for any needs going forward!"

"1st Class did a great job cleaning the windows and vinyl on my home. The windows were in rough shape and they helped me remove the old screens and get all of the dirt and cobwebs that had built up. Would definitely recommend and use them again!"
