Frequently Asked Questions

What Is foundation repair?
Foundation repair refers to the methods used for stabilizing and underpinning the building that has suffered a problem in its foundation. Usually, you need foundation repair of your home or business when its core structure gets damaged or distressed due to various reasons. These include poor drainage, plumbing leak, flood, earthquake, etc.

Usually not. Insurance companies tend to treat waterproofing as a preventive measure, not a repair after a covered event. That said, if damage from a sudden event (like a burst pipe or storm surge) is verifiable, there may be coverage, but policies vary. We always encourage customers to check with their insurer before counting on coverage.

Foundation repair becomes necessary when your building’s foundation starts to sink, crack, or settle. At the time of your building’s construction, it settles into the foundation with time slowly. But this is normal if your property is correctly built. However, if the property is not constructed correctly, it settles further than expected. This causes shifting of walls, floors, and other problems.

The selection of a suitable foundation repair method depends on the type of foundation damage. There are different methods used for foundation repair, which include, but are not limited to, the following:

  • Helical piers
  • Steel piers
  • Concrete piers for foundation repair
  • Segmented piers
  • High-density polyurethane foam
  • Spot piers

On average, foundation repair costs more than $4000 to the homeowners or $1800 to $6500. This depends on the kind of foundation repairs and the extensiveness of damage. Minor repairs often cost around $500, while major repairs can cost more than $10,000. The prices also vary according to the experience of a professional foundation repair company.

There’s no one-size-fits-all answer. The “best” method depends on where water enters, soil conditions, and your budget. We typically combine exterior waterproofing (excavation, waterproof membranes, proper grading) with interior drainage (French drains, sump pumps) to catch and direct water before it damages your foundation. The ideal system is tailored to your home’s vulnerabilities and backed by our workmanship and warranties.

Both approaches have advantages and many of our best results come when we use a hybrid approach:

  • Exterior waterproofing protects your foundation walls from the outside — preventing water from getting in to begin with.
  • Interior waterproofing catches leaks that do get through (or homes where exterior work is restricted) and channel water toward a sump pump.


If grading, landscaping, or other constraints exist, we’ll recommend the combination that gives you the strongest protection in your situation.

With solid installation and maintenance, it can last for decades. Our systems come with warranties (some transferable). Because we handle both exterior and interior components, many clients enjoy dry basements for the life of the structure. That said, key components like sump pumps or drainage lines may need periodic checks or replacement over time.

Yes, a dry, structurally-sound basement makes a home more appealing to buyers. It reduces buyer concerns about mold, flooding, and structural damage. The transferable warranties we offer also serve as a selling point, giving confidence to future owners.

Watch for warning signs such as:

  • Damp spots on walls or floors
  • Bubbling, peeling, or warped paint
  • Efflorescence (white, chalky residue)
  • Musty or moldy smells
  • Visible cracks in walls or floors
  • Water pooling after heavy rain


We also recommend a professional evaluation. Many times what appears minor is a symptom of a larger water intrusion problem.

Here’s what we advise (and strive to embody ourselves):

  1. Local experience & reputation — someone who knows Northern Virginia’s soil and weather.
  2. Comprehensive evaluation — the company should inspect and explain causes, not just sell a canned solution.
  3. Written proposals with clear scope, warranty, and materials listed.
  4. Strong warranties & transferable guarantees.
  5. References & past project photos.
  6. Transparency in cost and no-pressure approach. We use a “no-obligation consultation” model.

Waterproofing itself is not structural repair, but water intrusion can lead to structural problems (e.g. cracked or bowed walls, settling).

Our role is to prevent moisture from undermining the foundation. If structural damage is already present, we’ll often combine waterproofing with foundation repair (pier installs, carbon fiber reinforcements, crack repair) to restore both dryness and structural integrity.
