The ground under Satsuma
St. Johns River and tidal creek lowlands
Low ground along the St. Johns, Black Creek, Julington Creek and the tidal creeks that feed them.
The water table here moves with the river. In a wet season it can sit right at the level of the crawlspace floor, and a tropical system or a nor’easter can put it above. Many of these are older pier-and-beam homes in established neighborhoods, so the wood has already had decades of humidity working on it. Floods here are slow and repeated rather than sudden.
Drainage first: a perimeter French drain and a sump sized for the volume, then a sealed liner and dehumidifier so the wood can finally dry out.
- Standing water under the house every rainy season
- Soft or sagging floors, especially near the middle of the house
- Wood rot on joists and sill plates
- Floor vents that smell like the river

How a Satsuma job runs
Three steps, and you see everything we see
Free inspection
During your inspection, we will enter your crawlspace to thoroughly assess what is going on. Photos, moisture readings, and hazardous risks will be collected and then delivered to the homeowner to review. We will provide our recommendation, explain your options and offer a general estimate.
Written quote
A service quote will be sent to the homeowner containing all the information and prices of each solution for the crawlspace. After review and acceptance we will schedule a good time for repair and improvement services to begin.
The work
A team will come out and begin clearing out old construction debris, and organic matter. Whether you are receiving a full encapsulation or just a clean out, we are committed to finishing each job with excellence.
Questions from around Satsuma
Straight answers
Do you actually work in Satsuma?
Yes. Firm Foundations is based in Jacksonville and Satsuma (Putnam County) is inside our regular service area. Josh does the inspection himself.
What does encapsulation cost in Satsuma?
It depends on the size of the crawlspace, how much clean-out is needed, and whether water has to be managed first. The inspection is free and the written quote prices each solution separately, so you can stage it if you want to.
Why does my neighbor in Satsuma need a different system?
The water table here moves with the river. Two houses on the same street can sit a foot apart in elevation and take water completely differently, which is why we read each crawlspace before quoting.
How fast can you get here?
Free inspections in Satsuma are usually within a few days. Call or text (252) 773-2346 and Josh will get you on the route.
Do I have to be home?
For the inspection, yes, so Josh can walk you through the photos and readings. For the work itself, most homeowners are not — everything happens under the house.
