Common Fayetteville foundation repair questions with real numbers: full repairs $4,000–$15,000, piers $1,200–$3,000 each, drainage $1,500–$6,000. The free elevation survey decides which one your house needs.
How much does foundation repair cost in Fayetteville?
Most full repairs run $4,000-$15,000, piers $1,200-$3,000 each, slab work $3,500-$12,000, drainage correction $1,500-$6,000, and crack repair $400-$1,500. Void filling is priced by measured volume. The floor elevation survey that decides which applies is free.
Why do Northwest Arkansas foundations move?
Two mechanisms. The Ozark Plateau is karst - limestone dissolved along its joints - so concentrated water carries fine soil into the openings and support is permanently lost. Separately, pockets of expansive clay swell and shrink with moisture. Soil type can change inside one lot, so both can occur under a single house.
Do I need piers, or just drainage?
The elevation survey answers it. A house reading near flat with cracks that have not changed through a full wet-and-dry cycle needs water managed and monitoring. A house reading an inch or more low in a defined zone needs support there. A meaningful share of the houses we survey need drainage only.
Which cracks actually matter?
Width, direction, and change - not length. Hairline vertical cracks are usually shrinkage. Stair-step cracks through brick mortar, horizontal cracks in a foundation wall, anything wider than a quarter inch, and anything growing month over month indicate movement and deserve a survey before sealing.
Does insurance cover foundation repair in Arkansas?
Rarely. Standard policies exclude earth movement, which covers both karst soil loss and clay movement, and sinkhole collapse is typically excluded with it. The exception that pays is damage from a sudden accidental plumbing discharge under the slab. Establish the cause before you file anything.
Should I worry about sinkholes?
Less than the region's reputation suggests, but the question deserves a real answer rather than reassurance. Most movement we evaluate has an ordinary cause. Probing and elevation readings distinguish an ordinary problem from actual subsurface soil loss, and that difference is measurable rather than speculative.
How long does the work take?
Two to five days for most pier jobs, with nearly everyone staying in the house. Drainage corrections are frequently a single day. Concrete leveling is hours. Void filling depends on volume. Timelines are in the written scope before anything starts.
Is there a warranty?
On pier work, yes - and read it before the price. It covers the piered section holding its design load, not the whole house. Ask whether it transfers to the next owner, what a transfer costs, whether it is third-party backed, and whether it depends on drainage maintenance you owe.
