We aren’t done yet. Get ready to be horrified by these pressure washing fails:

1. Did someone just scribble on your deck? Oh wait, yeah, you did.

Believe it or not, this mess was not made by a kid- it was done by someone improperly handling a pressure washer. 

Hence, the importance of having prior knowledge, and knowing the correct PSI settings beforehand.

Frequently asked questions

After seeing those satisfying (and horrendous) pressure washing photos, check out these FAQs.

How much does it cost to pressure wash a deck?

A 500 sq. ft. deck will cost around $200, making it $0.30 to $0.40 per sq. ft. However, note that several factors still affect the cost to pressure wash a deck, such as material, condition, size, and location.

Can you pressure wash a composite deck?

You can, but warning! 

We strongly suggest using an extremely low PSI setting to avoid damages and avoid voiding your warranty.

How long after pressure washing can you stain?

After pressure washing, wait 48 hours before staining. But you may have to wait longer if the humidity or temperature is high. Also, the surface must be completely dry before applying the stain to ensure a smooth coating.  

Should I pressure wash my deck?

Definitely. Every surface is prone to various dirt, grime, and contaminants, and the best way to thoroughly eradicate those issues is to pressure wash. However, we suggest reaching out to a professional if you’re uncomfortable taking on the task.


To see is to believe, most importantly if it’s about cleaning.
