Most homeowners wash their house when it finally looks bad enough to bother them. There is a better way to time it. Connecticut weather runs on a cycle, and your siding collects every season of it.
Spring is the main season
Winter leaves road salt, grime, and dead buildup on your siding and driveway. Then the pollen hits. Connecticut springs coat everything in yellow-green dust, and it sticks to damp siding. A spring wash clears the whole winter and the pollen in one visit, and your house looks clean for the part of the year you are actually outside looking at it.
Spring is also when you can see what winter did. Algae starting on the shaded side, mildew in the corners, a walkway that got slick. Catching it early is cheaper than catching it in three years.
Summer grows things
Heat and humidity are algae and mildew weather. The north side of your house, and any side shaded by trees, stays damp the longest, and that is where the green and black growth shows up. A mid-summer wash is the right call if the growth is already there, especially on walkways and steps, where algae gets slippery underfoot.
Fall is the prep wash
A fall wash clears the summer's growth before winter locks it in, and gets leaves, dirt, and grime off your driveway and walkways before the freeze. Clean concrete going into winter is safer concrete. Fall is also a good time if you are putting the house up for sale or hosting for the holidays and want the outside to look kept up.
How often does a house need it?
For most homes, a wash every one to two years holds up well. Houses on shaded, wooded, or damp lots grow algae faster and do better on a yearly wash. Open, sunny lots can stretch it longer. The honest answer is that your house tells you.
Signs it is time
- Green or black streaks and patches on your siding, especially the north side
- Siding that looks dull, chalky, or dirty up close
- White pollen and dust that does not rinse off in the rain
- Walkways or steps that feel slick when wet
- A driveway dark with tire tracks, oil spots, and ground-in dirt
If you are seeing two or three of those, the wash is overdue, not early.
Book the spring slot before spring
Spring is the season every homeowner wants, which means spring schedules fill first. Wally Power Wash opens its first season March 1, 2027, and we start scheduling in February, in waitlist order, founders first. The first 20 homes are the Founding 20, with founding rates locked and first pick of dates. Join the waitlist and your spring wash is handled before the pollen even lands.
