Frequently Asked Questions
How do I know if I have a foundation problem?▼
Common signs include cracks in walls or floors (especially diagonal cracks from door and window corners), doors and windows that stick or no longer close properly, uneven or sloping floors, gaps between walls and ceilings or floors, and visible cracks in the exterior foundation wall. Not all cracks indicate structural problems, but any crack wider than a quarter inch or showing displacement warrants professional evaluation.
How much does foundation repair cost?▼
Foundation repair costs vary dramatically based on the scope of work. Minor crack sealing may cost a few hundred dollars. Pier installation typically ranges from several thousand to tens of thousands of dollars depending on the number of piers needed and depth required. Complete foundation replacement is the most expensive option. Get multiple bids with detailed engineering specifications.
What causes foundation problems?▼
The most common cause is soil movement from moisture changes. Expansive clay soils swell when wet and shrink when dry, creating uneven pressure. Other causes include poor drainage directing water toward the foundation, plumbing leaks saturating soil, inadequate compaction during original construction, tree roots, and natural settlement over time.
Can foundation problems be permanently fixed?▼
Yes, when properly diagnosed and repaired using engineered solutions. Steel push piers driven to bedrock or competent load-bearing strata provide permanent stabilization. Helical piers offer similar permanence. The key is addressing the root cause, including drainage corrections, to prevent recurrence. Surface-only repairs without addressing underlying causes are temporary.
Does foundation repair affect home value?▼
Unrepaired foundation problems significantly reduce home value and can prevent sales entirely. Properly repaired foundations with documented engineering and transferable warranties typically restore most or all of the lost value. Disclosure of repairs is required in most states, but documented professional repairs with warranties are viewed favorably by buyers and lenders.
