The ground under Gainesville
Karst and clay uplands
Rolling ground over limestone, with clay-rich soils, springs and the occasional sinkhole.
West and south of the metro the ground changes. Clay in the soil holds water against piers and footings and moves as it wets and dries, so you see settlement and cracked block alongside the moisture problems. Limestone underneath drains through fissures to the aquifer, which is why springs and sinkhole lakes are common here and why drainage can be very different from one lot to the next.
Moisture control with a sealed liner and dehumidifier, drainage where clay holds water against the foundation, and an honest assessment of any pier or block movement before anything is sealed.
- Cracks in block piers or stem walls
- Doors that stick in the wet season
- Damp clay that never fully dries under the house
- Efflorescence on block

How a Gainesville 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 Gainesville
Straight answers
Do you actually work in Gainesville?
Yes. Firm Foundations is based in Jacksonville and Gainesville (Alachua County) is inside our regular service area. Josh does the inspection himself.
What does encapsulation cost in Gainesville?
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 Gainesville need a different system?
West and south of the metro the ground changes. 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 Gainesville 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.
