Helical piles in Sarasota, Florida

Much of Florida rests on limestone, and the Florida Geological Survey notes that the entire state is underlain by carbonate rocks. When the ceiling of a cavity can no longer carry the sediment above it, the surface can settle or collapse, which is why an engineer's review is common where sinkhole activity has been reported near Sarasota.

Helical piers suit that kind of site because crews can read installation torque and extend the shaft to soil that carries the load. Residential uses include underpinning, additions, screen enclosures and pool or deck supports.

Costs and what to ask

Residential helical piers commonly run about $1,400 to $3,000 each installed, depending on shaft size and number of helices, according to SlabLocal's cost guide, which also notes that excavation can add $200 to $500 per pier. Pricing in Sarasota will also follow depth to bearing soil, access and permit requirements. For a fuller breakdown, read our helical pier cost guide.

Questions to put to any installer in Sarasota:

• Who is the engineer of record, and what load and depth are they designing to?
• Do you provide torque readings for every pier at the end of the job?
• Are the shafts and brackets hot-dip galvanized, and what shaft size do you plan to use?
• Will you obtain the permit for my Sarasota address, and is the warranty in writing?

Get written quotes from at least two companies and ask each to explain how the pier count and depth were determined.
