Yes and no.
Yes, if you use the wrong equipment and ignore the safety measures; no, if you use the right equipment and follow the rules.
To successfully power wash a house, you need to take several safety measures to prevent damaging the surfaces.
Some of the damages caused by a power washer are irreversible. So, if you lack the skills and knowledge of how to power wash, it’s best to leave it to the professionals.
Some of the damages you can get when you power wash your house are:
- Mold and mildew growth caused by water build-up below your house’s siding
- Dents on surfaces being power washed such as siding, shingles, etc.
- Surface discoloration
- Cracks or splinting on wood surfaces
- And much more
That said, before you power wash, you’ve got to understand:
- The right amount of pressure to use
Power washing can be in two forms, i.e., pressure washing and soft washing. Surfaces like concrete can withstand a lot of pressure, meaning they can be pressure washed.
But in roof power washing and gutter cleaning, a soft wash is the way to go. This is because a large amount of pressure can easily cause water to go underneath roof shingles, causing damage.
- The distance required as you power wash
When using a power washer, distance is just as critical as the pressure you put. Too close to the surface can cause dents and scratches that are otherwise avoidable.
- The technique involved
Skills are necessary to power wash any surface; without proper knowledge and experience, a lot could go wrong.
The best way to avoid the damages
You’ve probably understood how much of a risk it is when you power wash on your own. So, why not leave the experts to it?
