The short answer
Assess the Severity First
Foundation issues range from small hairline cracks to serious shifting that compromises the structure. You can live in the house while you gather information, but you should not ignore signs like doors that stick, gaps around windows, or sloping floors. Those clues suggest the foundation is moving.
Start with a professional inspection to see whether the problem is cosmetic or structural. A water damage inspection looks for moisture intrusion that often worsens foundation damage. The inspector can tell you if the foundation is stable enough for daily living or if you should plan to move out temporarily.
Watch for Safety Hazards
Your safety comes first. If you notice large cracks in walls, bowing basement walls, or water seeping through the foundation, treat those as urgent. Water undermines the soil and can make the foundation shift more quickly. In a semi-arid climate with cold winters and hot dry summers, freeze-thaw cycles can widen existing cracks.
Check for gas leaks, electrical hazards, or mold growth. If you smell gas or see water near wiring, leave the house and call the right professionals. See a doctor if you feel unwell from musty odors or suspected mold exposure.
- Large diagonal cracks in walls or ceilings
- Doors or windows that no longer close properly
- Visible gaps between the foundation and the ground
- Water pooling in the basement or crawl space
- Cracks that keep growing wider over time
- Bowing or leaning foundation walls
Understand the Repair Options
Some foundation problems need only waterproofing and drainage fixes, while others require structural stabilization. If water is the culprit, addressing the moisture source can stop further damage. Foundation waterproofing keeps water away from the walls, and foundation stabilization helps anchor the structure.
The right approach depends on what the inspection reveals. A pro can explain whether you need to fix the grading, install a sump pump, or add supports. You can usually stay in the house while these repairs happen, but major work may require you to be out of certain rooms.
Plan for Water Damage Control
Water is often the hidden driver of foundation issues. Leaking pipes, poor drainage, or high groundwater can erode the soil under the foundation. If you suspect a leak, leak detection services can find the source before it worsens.
Once the leak is fixed, structural drying and dehumidification helps remove excess moisture from the crawl space or basement. This reduces the chance of mold and further wood rot. If you live in Caldwell, keep an eye on your downspouts and gutters to direct water away from the house.
Know When to Leave
You can live with minor foundation issues, but there are times when leaving is the safer choice. If the foundation is actively shifting, if walls are bowing, or if there is a risk of collapse, do not stay. Your insurance company may help with temporary housing if the damage is from a covered event.
Policies vary, and your insurer decides what is covered. Check your policy and ask a qualified attorney if you have questions about your rights. A structural engineer can provide a written opinion on whether the house is safe to occupy. Trust that advice over guesswork.

How do I know if foundation cracks are serious?
Small hairline cracks under a quarter inch wide are often cosmetic. Larger cracks, especially ones that grow or appear on both sides of the wall, suggest movement. Have a pro inspect them to measure the gap and check for moisture behind the wall.
Can foundation issues cause water damage inside?
Yes. Cracks in the foundation allow groundwater to seep into your basement or crawl space. That moisture can damage drywall, flooring, and insulation. It can also lead to mold growth. Fixing the foundation crack and improving drainage helps keep water out.
Should I stay in the house during foundation repairs?
It depends on the type of repair. Minor waterproofing or crack sealing is usually safe to live through. Major stabilization work, like underpinning or lifting the house, may make it unsafe and noisy. Ask the pro what to expect and plan for temporary stays if needed.
