Exterior Cracks: What They Mean For Your Home’s Foundation

Noticing a crack in your exterior concrete or siding? At G.L. Hunt Foundation Repair, we know how alarming it can be to spot damage on the outside of your home. While some minor exterior wall cracks may be cosmetic, others can signal deeper issues with your foundation — and ignoring them could lead to costly repairs down the line.

In this guide, we’ll walk you through what causes cracks in exterior walls, when to worry and how exterior wall crack repair works.

What Causes Cracks In Exterior Walls?

Cracks on the outside of your home don’t just appear out of nowhere. They’re typically the result of natural wear and tear, environmental conditions or underlying structural problems. Understanding the source is the first step in deciding how to address them.

Here are the most common causes of exterior foundation cracks:

  • Temperature fluctuations — Hot summers and sudden cold snaps can cause concrete and masonry to expand and contract, resulting in cracks.
  • Soil movement — In Texas, expansive clay soils swell and shrink with moisture levels, putting pressure on your foundation.
  • Foundation settlement — Over time, parts of your foundation may sink or shift, creating stress points that lead to cracking.
  • Poor drainage Water pooling near the base of your home can erode soil and weaken the foundation.

These factors can work alone or together, gradually shifting the foundation and causing visible signs of damage on the outside of your home.

When Is A Crack In The Exterior Wall A Problem?

Not all cracks are created equal. While hairline cracks may be harmless, others can indicate serious structural movement. So, how do you know which ones need attention?

Look for these warning signs that a crack in an exterior wall could be a red flag:

  • The crack is wider than 1/4 inch
  • You notice stair-step cracks in brick or block
  • Cracks are getting longer or wider over time
  • There are multiple cracks around the home’s perimeter
  • Doors and windows nearby are sticking or misaligned

If you notice any of these signs, it’s time to bring in a professional. These symptoms often mean your foundation is shifting, and early intervention can prevent more extensive damage.

Commonly form 1-2 months after foundation pouring. Usually minor if hairline and stable, but should be regularly monitored for signs of spreading or widening.

What Does Exterior Wall Crack Repair Involve?

Once the cause of the cracks is identified, the next step is deciding how to repair them. At G.L. Hunt, we don’t believe in one-size-fits-all solutions. Instead, we provide targeted repairs based on the condition of your home and foundation.

Here are some of the common techniques we use for exterior wall crack repair:

  • Foundation pieringInstalling support piers beneath the foundation to stabilize and lift affected areas helps prevent further shifting and restores structural integrity.
  • Concrete repair — If foundation movement has caused cracking or displacement in nearby concrete features — like sidewalks, driveways, porches or stair steps — we can restore these surfaces to improve both safety and curb appeal.
  • Water management — We can improve drainage around your home to reduce soil movement and prevent future cracking. This might include regrading, installing French drains or adding downspout extensions.

These solutions are designed not just to fix the current cracks, but also to address the root causes and prevent them from coming back.

Should You Fix Exterior Foundation Cracks Right Away?

In a word — yes. Even small cracks can widen over time and allow water intrusion, pest entry or structural weakening. More importantly, a crack in exterior concrete could be an early indicator of foundation failure.

Delaying repairs may lead to more complex (and expensive) problems. Having a professional inspect the issue can give you peace of mind and help you make informed decisions about your home.

FAQs

What Is Foundation Repair?

Foundation repair refers to the process of correcting structural problems in a building’s foundation that can compromise the safety, value and usability of the property. These issues often arise from soil movement, poor construction, water intrusion or age-related wear and tear.

Typical signs that foundation repair may be necessary include:

  • Cracks in walls or ceilings
  • Doors and windows that stick or won’t close properly
  • Uneven floors or gaps between walls and floors

Common repair techniques include:

  • Underpinning – Strengthens the foundation by extending it to more stable soil using piers or piles.
  • Piering – Uses steel pipe piles driven into the ground to lift and support the foundation.
  • PolyLevel – Involves injecting a foam mixture beneath the slab to lift it back into place.

A professional foundation inspection is key to diagnosing the root problem and determining the appropriate repair method. Timely repairs can prevent more costly damage and help maintain — or even increase — your home’s resale value.

Can You Live In A House During Foundation Repair?

Yes, in most cases, homeowners can remain in their house during foundation repair. However, this depends on several factors, such as:

  • Scope of the repair – Minor exterior work is less disruptive than full-scale interior structural repairs.
  • Type of foundation – Pier-and-beam homes might require more interior access than slab foundations.
  • Location of the damage – Repairs under major living spaces, like kitchens or bathrooms, could limit access.

You can expect temporary inconveniences such as:

  • Loud construction noise
  • Dust and debris in work areas
  • Limited access to certain rooms or outdoor areas

Our experienced team prioritizes safety and works efficiently to minimize disruption. If repairs become extensive or involve utilities (like plumbing), temporary relocation may be recommended — but this is rare.

How Long Does Foundation Repair Take?

The length of time required for foundation repair can vary significantly depending on:

  • Severity of the damage – Minor cracks may be addressed in 1–3 days, while major stabilization projects can take 1–3 weeks.
  • Type of repair method – PolyLevel is quicker than pier installation or extensive structural reinforcement.
  • Weather conditions – Heavy rain or freezing temperatures can delay work, especially when soil stabilization is involved.
  • Accessibility – Tight crawlspaces or densely landscaped yards can require additional labor and time.

Your contractor should provide a clear, personalized project timeline during the initial assessment. At our company, we value transparency and keep homeowners informed at every stage of the repair process.

Should I Buy A House With Foundation Repair?

Buying a house with prior or ongoing foundation repairs isn’t necessarily a deal-breaker — in fact, it can be a sign the current owner has proactively addressed structural concerns. However, due diligence is essential. Consider the following steps:

  • Request documentation – Get copies of inspection reports, repair warranties and permits.
  • Hire a third-party inspector or structural engineer – An unbiased opinion ensures the repairs were done correctly and safely.
  • Understand the extent of the repairs – Cosmetic fixes are different from major structural reinforcements.
  • Factor it into negotiations – Repairs may lower the home’s value or require additional monitoring.

If you’re unsure, our team can provide insights or connect you with a local expert to review the foundation repair history before you make a purchase.

Does Home Insurance Cover Foundation Repair?

In most cases, standard homeowners insurance does not cover foundation repair costs caused by routine settling, soil shifts or natural aging. However, there are exceptions based on the source of the damage. Coverage may apply if the issue stems from:

  • A burst pipe or plumbing leak (if sudden and accidental)
  • Fire or explosion
  • Earthquake or flood (if you carry specific endorsements)
  • Storm damage (like fallen trees causing foundation cracks)

To determine if you’re covered:

  • Review your policy for exclusions or limitations related to foundation damage.
  • Contact your insurance agent for clarification based on the exact cause of damage.
  • Consider add-ons like water backup, flood, or earthquake coverage, especially in risk-prone areas.

If your repairs aren’t covered, we offer flexible financing options to help make foundation work more affordable. Reach out to learn more.

Can A Bad Foundation Be Fixed?

Yes, even a severely compromised foundation can often be repaired — but the success and approach depend on the extent of the damage and how early it’s addressed. Modern foundation repair techniques can correct settling, cracking, bowing walls and shifting soil conditions.

Professional contractors use structural assessments to develop a tailored solution, which may involve:

  • Underpinning with steel or concrete piers to stabilize and lift the foundation
  • TexJack for pier support in lightweight or limited-access structures

  • Sonotube concrete forms for supporting settled or sunken slabs

Even if your foundation shows serious issues, repairs can often restore both structural integrity and long-term value — but delaying action can make repairs more complex and costly. An expert evaluation is key to identifying the best fix.

Will Foundation Repair Damage My Landscaping Or Plumbing?

Some degree of disturbance is possible during foundation repair, especially for exterior work, but a skilled contractor will work to minimize impact on your landscaping and plumbing.

Here’s what to expect:

  • Landscaping — Some digging near the perimeter of the home may be required to install piers or access the foundation. This can temporarily affect flower beds, sod or shrubs near the work zone.
  • Plumbing — In some cases, especially with slab foundations, repairs may require temporary disconnection or adjustment of plumbing lines. A hydrostatic plumbing test may be recommended to ensure no pipes are damaged during lifting or movement.

For peace of mind, ask your team how we protect landscaping and how plumbing is tested or monitored as part of our process. We take great care to minimize disruption and restore your home’s exterior appearance post-repair.

What Are Common Foundation Repair Methods?

Foundation repair isn’t one-size-fits-all — contractors choose methods based on soil type, structural design, extent of damage and budget. Here are the most widely used foundation repair techniques:

  • PieringSteel piers or concrete piers are driven deep into stable soil or bedrock and used to lift and support the structure.
  • Underpinning — A broader category of reinforcing the existing foundation, often using piers or by pouring new concrete beneath weakened areas.
  • Wall Anchors or Bracing — Used to stabilize bowed basement walls or retaining walls, often with steel anchors or carbon fiber straps.
  • Soil Stabilization — Expansive or shifting soils can be treated with chemical injections to reduce movement and improve bearing capacity.

A trusted contractor will perform a foundation inspection and explain which method is most effective — and why — for your specific property.

Is It Safe To Live In A House With A Foundation Problem?

It depends on the severity of the issue, but in many cases, it is safe — at least temporarily. That said, foundation problems can worsen over time and lead to safety concerns or further damage if left unaddressed.

Risks include:

  • Uneven floors that can cause trips and falls
  • Doors or windows that jam, reducing emergency exit accessibility
  • Structural stress that may affect plumbing, walls and roofing systems
  • Moisture intrusion leading to mold or indoor air quality issues
  • Cracks in walls may weaken the structural integrity of the home

If you notice signs like widening cracks, large wall gaps, or severe sloping floors, it’s best to schedule a professional evaluation immediately. For peace of mind and to avoid costly future repairs, we recommend not ignoring early symptoms, even if they seem minor.

What Causes Foundation Problems?

Foundation problems often result from shifting soil, moisture imbalance, poor construction or natural aging. The most common culprits include:

  • Expansive clay soils — These soils swell when wet and shrink when dry, creating movement that stresses the foundation.
  • Poor drainage or plumbing leaks — Excess water near the foundation can erode soil, causing settling or hydrostatic pressure against basement walls.
  • Tree roots — Large roots can dry out soil under the foundation or disrupt soil structure.
  • Inadequate site preparation — If the soil wasn’t properly compacted before construction, the foundation may settle unevenly.
  • Seasonal weather changes — Droughts and heavy rains cause soil to contract and expand repeatedly, weakening support.
  • Natural aging — Over time, foundations naturally experience some wear, especially in older homes.

Knowing the underlying cause helps determine the best repair method and whether preventative measures (like improved drainage or root barriers) should be installed to protect the foundation long-term.
