Foundation Repair

Slab Foundation Repair in District of Columbia

Q: A foundation company says I need $40,000 in piers. Another says my cracks are cosmetic. Who's right?

Foundation diagnosis is genuinely difficult and subject to overselling. Independent structural engineers (not affiliated with repair companies) provide the most objective assessments for $300–$600. A licensed structural engineer's report can tell you definitively what's happening and what's required. Get this before accepting any large repair quote.

Q: My house is settling and doors are sticking. Is this always a foundation problem?

Not always. Door sticking in summer/fall can be wood expansion from humidity. Foundation settlement causes consistent sticking year-round, and is usually accompanied by other signs: sloping floors, cracks radiating from door corners, gaps between walls and ceiling, or gaps around exterior doors and windows. Have a structural engineer evaluate if you have multiple symptoms together.

Q: What's the difference between push piers, helical piers, and concrete pilings?

Push piers are hydraulic steel pipes driven to load-bearing soil/bedrock — best for stabilizing settled areas. Helical piers are screwed into soil and can be used in tighter spaces. Concrete pilings are poured-in-place — common in warmer climates with expansive clay soils. The right method depends on soil conditions, load, and access. Any reputable company should perform a soil assessment before recommending.

Q: Will foundation repair increase my home's resale value?

A repaired and warranted foundation is far better for resale than an unaddressed one. Foundation issues that are disclosed but unrepaired significantly reduce buyer offers and can kill sales. A transferable lifetime warranty from a reputable foundation company is a selling point. The repair itself rarely adds dollar-for-dollar value, but it removes a major obstacle to sale.

Q: How long does foundation repair typically take?

Pier installation for a typical 3–5 pier job: 1–2 days of work. Interior waterproofing system: 1–3 days. Carbon fiber crack reinforcement: a few hours. Most foundation repairs are completed in 1–3 days. Excavation-based exterior waterproofing is more disruptive — 3–7 days. Make sure the company clearly specifies what post-repair grading, backfill, and cleanup is included.

Common questions

Frequently asked questions in DC

I have cracks in my foundation. How do I know if they're serious?

Horizontal cracks in basement walls are always serious — they indicate soil pressure and potential wall failure. Stair-step cracks in block or brick foundations indicate settlement and need evaluation. Vertical cracks under 1/4" wide that don't grow are usually shrinkage cracks — monitor them with crack monitors for 6–12 months. Any crack that's widening, has water intrusion, or is wider than 1/4" needs professional evaluation.
