A foundation inspection can uncover serious issues in your home that may otherwise go unnoticed. This type of inspection goes beyond surface-level charm and aesthetics to assess the foundation that holds your home together.
If you have cracks in your foundation, an inspection will tell you if they’re nonstructural or serious.
Whether you’re a homeowner protecting your investment or a savvy buyer scouting for a stable property, understanding the ins and outs of foundation inspections is vital to avoiding sinking feelings and rising repair costs.
Why are foundation inspections necessary?
When it comes to keeping your home safe and sound, foundation inspections are a must. Foundation inspections help with the following:
- Maintaining a home’s structural integrity: Regular foundation inspections help ensure your home’s structure remains strong and stable.
- Identifying issues early: Catching foundation problems early can prevent major headaches and expensive repairs later.
- Boosting real estate transactions: If you’re buying or selling a home, including a manufactured home, a foundation inspection is essential to make sure there are no hidden issues that could affect the value or safety of the property.
- Offering peace of mind: Knowing your foundation is in good shape gives you the confidence to enjoy your home without worrying about underlying problems.
What types of foundations exist?
Several different types of foundations, each with unique characteristics, can benefit from regular inspections.
Poured concrete slab
A poured concrete slab is a flat, thick section of concrete, typically 8 inches thick, reinforced with rebar but often lacking footings. This type is affordable and easy to install, making it popular in warmer climates where ground freezing is not a concern.
Regular inspections for poured concrete slabs are essential to catch cracks or shifting that could compromise the entire structure they support.
Crawl space
A crawl space foundation features short masonry walls along the perimeter and footings underneath the center, creating a space with a dirt floor and limited ceiling height. These foundations are ideal for sloped or rocky terrain and regions prone to freezing.
Inspections for crawl space foundations are vital to check for moisture issues, pest infestations and structural integrity of the supports.
Slab-on-grade
Slab-on-grade foundations are heavy-duty concrete slabs with footings that disperse the building’s weight, often reinforced with rebar. They provide more strength and stability than basic poured slabs and are suitable for cold-weather regions due to their resistance to ground heaving.
Inspecting slab-on-grade foundations helps identify any shifts or cracks that could affect the stability and evenness of the floors. Josh Kemp, director of research and development at Olshan Foundation Solutions, a national company, added, “Under-slab plumbing should be tested by a licensed plumber every five to seven years.”
Full basement
A full basement foundation includes deeply dug footings, standing-height walls and a concrete slab, providing extensive space for various uses such as storage or additional living areas. Basements are known for their flexibility and strength but are costly and time-intensive to build.
Regular inspections of full basements can detect water leaks and structural cracks.
Insulated concrete form (ICF)
Insulated concrete forms are modern foundations using interlocking styrofoam forms filled with concrete, providing excellent insulation and strength. These foundations are easy to install and act as a vapor barrier, making them suitable for energy-efficient homes.
Inspecting ICF foundations ensures that the insulation remains intact and that there are no breaches in the vapor barrier that could lead to moisture problems.
What types of foundation problems do inspections find?
Foundation issues can lead to significant damage, safety issues and costly repairs. Here are some common foundation problems an inspection may uncover.
Vertical cracks
Vertical cracks in your foundation are typically signs of settling, which can be normal. However, if these cracks widen or appear rapidly, it could indicate a more severe issue.
Horizontal cracks
Horizontal cracks are more concerning than vertical ones, as they often indicate pressure from the soil outside the foundation. Tim Tracy, director of sales training for Virginia-based Groundworks confirmed, “Horizontal cracks are especially concerning, as they indicate uneven settling and significant stress.”
These cracks can lead to bowing walls and, eventually, structural failure.
Bowing walls
When foundation walls bow inward, it’s usually due to external pressure from water-saturated soil. Bowing walls can compromise the structural integrity of your home, leading to potential collapse.
Sloping or uneven floors
Uneven floors can result from the foundation settling or shifting. This issue can cause doors and windows to misalign and indicate serious problems beneath the surface.
Water damage
Water damage around your foundation can lead to mold, mildew and rot, weakening the structure. Persistent moisture around the foundation is a red flag that signals the need for your immediate attention.
Sinkholes
Sinkholes or depressions around your foundation can indicate severe ground movement or erosion. This can lead to a sudden and catastrophic foundation collapse. Luckily, large collapses due to sinkholes are rare.
When should you get a foundation inspection?
Certain scenarios warrant an inspection more than others. Here are four times when you should consider getting a professional foundation inspection.
Watch for foundation problems, including significant wall cracks, uneven or sloped floors, mildew or standing water, and stuck doors and windows.
Regular inspections conducted by qualified professionals every few years can catch problems early and prevent costly repairs.
A thorough foundation inspection assures safety and can be a negotiating point.
Following floods, earthquakes or other disasters, it’s essential to assess the foundation to prevent further damage and provide peace of mind regarding the safety and stability of your home.
What does the foundation inspection process look like?
When a foundation inspector arrives at your home, they’ll start by discussing your concerns about your foundation. Then, they’ll conduct a thorough visual inspection of the exterior, looking for cracks in the cement, bricks or fascia boards. For homes with pier and beam foundations, they’ll enter the crawlspace to check for dampness and assess the condition of piers, beams and joists.
Inside, the inspector will look for visible cracks in floors, walls and ceilings and measure the levelness of your foundation. After completing the inspection, the inspector will provide you with a report.
Here’s an example of a foundation inspection checklist in Nevada County, California. These could vary based on your location.
What do you do with the report?
A foundation inspection report includes descriptions and photographs of any potential issues identified during the inspection. The report will also provide recommendations for repairs or further assessments needed to address these issues effectively.
Understanding the inspection report is crucial for making informed property maintenance or purchase decisions, so don’t be afraid to ask questions or seek clarification.
How much does a foundation inspection cost?
The cost of a foundation inspection varies depending on several factors, including your property’s size and layout, where you live and how complex of an inspection is required. Reach out to a structural engineer or an inspector about your foundation inspection to get an idea of what it might cost.
How long does a foundation inspection take?
A foundation inspection typically takes a few hours, depending on the size and complexity of your property. Larger homes or properties with intricate foundation systems may require more time for a thorough assessment.
Can you do your own foundation inspection?
Some DIY methods can help spot potential problems when inspecting your foundation. Kemp recommends that homeowners conduct regular inspections. “Look for nonuniform cracks that continue to increase and grow.”
However, nothing beats the expertise and tools of a professional. A qualified foundation inspector brings years of experience and specialized knowledge to the table, ensuring a thorough examination of your home’s foundation.
Can foundations be repaired?
Many issues identified during a foundation inspection can be fixed. Here are some standard ways to repair foundation cracks.
- Epoxy injections for cracks: Epoxy fills and seals cracks in concrete foundations, preventing water intrusion and reinforcing the structure.
- Reinforcement with steel beams or piers: These beams are installed to provide additional support and stability to foundation walls or slabs that have shifted or settled.
- Waterproofing measures: This involves applying sealants and barriers to prevent moisture from penetrating the foundation.
- Fixing drainage problems: According to Tracy, proper drainage is paramount. He advised, “Implement appropriate grading, gutters and downspouts to redirect water away from the foundation.”
When addressing foundation repair, choosing the right contractor is crucial. Look for licensed, experienced contractors with positive reviews from previous clients. Get multiple estimates and ask for references to ensure you hire a reputable professional.
What’s next?
After a foundation inspection, review your report carefully. Look for recommendations on repairs or maintenance tasks that need immediate attention. Prioritize these based on severity to prevent further damage. Contact licensed contractors for estimates and begin planning necessary repairs.
Looking ahead, make it a priority to schedule regular foundation inspections every few years, especially after significant weather events or if you plan to buy or sell your home. This proactive approach can save you from unexpected expenses and provide peace of mind, knowing your foundation is in good condition.
Remember, when in doubt, seek professional advice from qualified foundation inspectors or structural engineers. Their expertise and thorough assessments can help detect potential issues early and prevent them from escalating into costly repairs or compromising your home’s safety.
