The ground under Palm Valley
Barrier islands and the Intracoastal
Beach sand and shell over a water table a few feet down, with salt air on everything.
Sand drains fast, which sounds good until you remember the water table underneath is only a few feet below your crawlspace. King tides, tropical rain and storm surge push it up from below rather than in from the side. Salt air corrodes duct straps, hangers and nails, and constant sea-breeze humidity means a vented crawlspace out here is never dry, even in a drought.
Full encapsulation with a sealed liner and dehumidifier, stainless or coated fasteners, and a sump where the water table reaches the crawl floor in storm season.
- Damp sand and a salt crust under the house after high tides
- Rusted duct straps, hangers and nail heads
- Musty smell that gets worse with an onshore breeze
- Standing water under the house for days after a storm

How a Palm Valley 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 Palm Valley
Straight answers
Do you actually work in Palm Valley?
Yes. Firm Foundations is based in Jacksonville and Palm Valley (St. Johns County) is inside our regular service area. Josh does the inspection himself.
What does encapsulation cost in Palm Valley?
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 Palm Valley need a different system?
Sand drains fast, which sounds good until you remember the water table underneath is only a few feet below your crawlspace. 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 Palm Valley 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.
