Most exterior cleaning advice online is written for nowhere in particular. It tells you to wash your house twice a year without knowing whether you live under an oak canopy in Riverside or on a cleared lot in Nocatee, and it never mentions that half of Clay County has iron in the well water.

These are written for this region specifically. Each one answers a question we actually get asked, including the times the honest answer is that the job can wait.

Method & safety

6 min read Surfaces You Should Never Pressure Wash

Nine surfaces where pressure causes damage that cannot be undone — and what to use instead.

Roofs

5 min read Black Streaks on Your Roof: What They Actually Are

Not dirt, not staining, not shingle failure. A cyanobacteria that is digesting part of your roof.

Concrete

5 min read Why Your Driveway Looks Worse After Pressure Washing

Tiger stripes, revealed patchwork and exposed aggregate — what went wrong and whether it can be undone.

What to expect

5 min read Will Pressure Washing Kill My Plants?

The single most common concern we hear. Here is the actual mechanism, and the step that matters most.

Hiring

6 min read How to Choose a Pressure Washing Company

Eight questions, the answers that should reassure you, and the ones that should not.

 6 min read Should You Pressure Wash It Yourself?

Some of this work is genuinely worth doing yourself. Some of it will cost you far more than hiring would have.

Walls & siding

5 min read Why Is My Stucco Turning Green?

It starts on the north wall, every time. Here is why, and why pressure alone makes it come back faster.

Coastal

5 min read How Salt Air Damages Coastal Home Exteriors

Salt is hygroscopic — it pulls moisture from the air and holds it against your house. That is the whole problem.

Value

5 min read Is Pressure Washing Actually Worth It?

Some of this work protects an asset. Some of it is purely how things look. Worth knowing which is which.

Why local advice is different advice

Northeast Florida creates a specific set of exterior problems, and most of them do not appear in generic maintenance advice written for a national audience.

  • Roughly 52 inches of rain a year and mild winters. Nothing dies back over the cold months, so organic growth is a year-round process rather than a seasonal one.
  • Live oak canopy across much of Duval County. Shade keeps walls damp, and the litter that falls from oaks feeds what grows on them.
  • Iron in the groundwater across large parts of Clay and Nassau counties. That is why so many driveways here have orange sprinkler arcs that no amount of pressure will shift.
  • Salt reaching well inland on the easterly. It holds moisture against surfaces, which corrodes metal and accelerates algae at the same time.
  • Oak pollen through March and early April. Anything washed during that window needs washing again.

Advice that ignores all five will tell you to wash your house twice a year and leave it there. Which is not wrong, exactly — it is just not useful for deciding what your particular property needs.

Looking for something specific?

A few things get asked often enough that they live on their own pages rather than in a guide:

If something is not covered here and you think it should be, tell us — most of these were written because somebody asked.

Still not sure what your property needs?

Send a few photos. We will tell you what we would do and roughly what it costs, including if the answer is that it can wait.
