Most Tulsa homes should be soft washed once a year, and homes under heavy shade or with north-facing walls that stay damp often need it twice a year. How often to wash a house in Tulsa depends less on the calendar than on how fast algae and mildew stains build up on your walls.
This guide is about how often. Which month to book is covered in our separate guide to the best time of year to wash a house in Tulsa.
What speeds up the schedule
Shade and moisture speed up the schedule more than anything else, because algae and mildew need both to grow. Tulsa's humid summers supply the moisture; your lot decides the rest.
- Mature trees shading the house — common in South Tulsa and Midtown
- North-facing walls that rarely get direct sun and stay damp after rain
- Lawn sprinklers that hit the siding
- Gutters that overflow and streak the walls below
- New construction nearby, where red dirt blows onto the siding
Signs it's time now
Your house needs a wash when you can see growth, not when the calendar says so. Check the north side first — it shows staining before the rest of the house.
- A green or black film on shaded walls
- Dark streaks below gutters and window sills
- Siding that looks dull next to a neighbor's freshly cleaned home
- A notice from your HOA about mildew or dirty siding
Why waiting costs more
Waiting several years between washes makes each wash a bigger job, because organic growth compounds. The longer algae and mildew sit, the deeper the staining sets and the more cleaning it takes. A yearly soft wash keeps every visit light.
Washing more often still means a soft wash each time: low pressure and a cleaning solution made for vinyl, brick, stucco, and painted surfaces, with no high pressure on the siding.
How often to clean the rest of the exterior
- Gutters — at least twice a year, and more under mature trees
- Roof — when black algae streaks appear, not on a fixed calendar
- Windows — at the same visit as the house wash, since dirty glass stands out next to clean siding
- Driveway — whenever it turns gray or stained, and before a listing or a big event
Twice a year without having to remember
The Season Care Plan puts the soft wash, gutter cleaning, and window cleaning on one visit, twice a year — usually once in spring and once in fall. It's quoted per home, and the quote is free.
