Understanding Why Houses Sink
Before we dive into spotting the signs, let’s quickly cover why houses sink in the first place. It’s usually not as dramatic as it sounds! Several factors can contribute:
- Soil Problems: The ground beneath your house can shift. Clay soil expands when wet and shrinks when dry, causing movement.
- Poor Construction: Sometimes, the foundation wasn’t built properly to begin with.
- Water Damage: Leaks or poor drainage can erode the soil around your foundation.
- Tree Roots: Large tree roots can suck moisture from the soil, leading to uneven settling.
- Natural Disasters: Earthquakes or floods can definitely mess with your foundation.
Knowing these causes can help you understand what to look for and potentially prevent further issues.
Step-by-Step Guide: How to Tell if Your House is Sinking
Alright, let’s get to the nitty-gritty! Here’s a step-by-step guide to help you determine if your house might be sinking. Remember, seeing one sign doesn’t automatically mean disaster, but multiple signs warrant a professional inspection.
Step 1: Inspect Interior Walls
Your interior walls can tell you a lot about your house’s stability. Here’s what to look for:
- Cracks: Pay close attention to cracks, especially those around door frames, window frames, and where walls meet ceilings. Hairline cracks are common in new houses as they settle, but larger, diagonal cracks are more concerning.
- Uneven Surfaces: Use a level to check if your walls are plumb (perfectly vertical). If a wall is leaning or bulging, it could indicate foundation movement.
- Wallpaper or Paint Issues: Look for areas where wallpaper is peeling or paint is cracking, as this can also point to wall movement.
Pro Tip: Take photos of any cracks you find. This will help you track if they’re getting bigger over time.
Step 2: Check Doors and Windows
Doors and windows that stick or are difficult to open and close can be a sign of foundation issues. Here’s what to do:
- Test Doors and Windows: Open and close all the doors and windows in your house. Do they stick, bind, or require extra force to operate?
- Look for Gaps: Check for gaps around the frames of doors and windows. These gaps can appear if the house is shifting.
- Examine the Frames: Look for cracks or separations in the door and window frames themselves.
Safety First: If a door or window is extremely difficult to open, don’t force it. You could damage the frame or injure yourself.
Step 3: Evaluate Floors
Sloping or uneven floors are a pretty clear indicator that something’s not quite right. Here’s how to check your floors:
- Use a Level: Place a level on different areas of your floor. If the bubble isn’t centered, your floor isn’t level.
- The Marble Test: Place a marble on the floor and see if it rolls on its own. If it does, that indicates a slope.
- Look for Visible Sloping: Sometimes, you can see the slope with your own eyes. Stand in a doorway and look across the room. Does one side of the floor appear higher than the other?
Important Note: Older homes often have some degree of unevenness, but significant sloping is a red flag.
Step 4: Inspect the Foundation
This is where you get down and dirty (literally!). Your foundation is the base of your house, so any problems here are serious. Here’s what to look for:
- Cracks: Check for cracks in the foundation walls. Hairline cracks are usually normal, especially in concrete foundations, as the house settles. However, large cracks (wider than 1/4 inch), diagonal cracks, or cracks that are widening are cause for concern.
- Bulging or Bowing: Look for areas where the foundation walls are bulging inward or bowing outward. This indicates significant pressure from the surrounding soil.
- Water Stains: Check for water stains or efflorescence (a white, powdery substance) on the foundation walls. These can indicate water intrusion, which can weaken the foundation.
- Shifting or Sinking: Look for signs that the foundation is shifting or sinking, such as a visible gap between the foundation and the soil.
Safety First: When inspecting your foundation, wear gloves and eye protection. Be careful of spiders, insects, and other critters.
Step 5: Check Exterior Walls
Your exterior walls can also show signs of sinking. Here’s what to look for:
- Cracks: Look for cracks in the exterior walls, especially around doors, windows, and where the walls meet the foundation.
- Separation: Check for separation between the walls and the foundation.
- Chimney Issues: If you have a chimney, check to see if it’s leaning or separating from the house.
Pro Tip: Use binoculars to get a closer look at hard-to-reach areas of your exterior walls.
Step 6: Examine the Roof
While it might seem odd, problems with your roof can sometimes indicate foundation issues. Here’s what to check:
- Sagging: Look for any sagging areas on the roof.
- Unevenness: Check for unevenness in the roofline.
- Gaps: Look for gaps between the roof and the walls.
Safety First: Don’t climb on your roof unless you’re comfortable and have the proper safety equipment. It’s often best to inspect the roof from the ground using binoculars.
Understanding Crack Patterns
Cracks are a common sign of settling, but not all cracks are created equal. Understanding the different types of cracks can help you determine the severity of the problem.
| Crack Type | Description | Level of Concern |
|---|---|---|
| Hairline Cracks | Thin cracks, usually less than 1/8 inch wide. | Low (common in new houses) |
| Vertical Cracks | Cracks that run straight up and down. | Moderate (monitor for changes) |
| Horizontal Cracks | Cracks that run horizontally along the wall. | High (can indicate significant foundation movement) |
| Diagonal Cracks | Cracks that run at an angle (usually 45 degrees or more). | High (often a sign of settling or structural issues) |
| Stair-Step Cracks | Cracks that follow the mortar joints in brick or block walls, resembling a staircase. | High (indicates differential settling) |
Important Note: Any crack that is wider than 1/4 inch, is growing, or is accompanied by other signs of sinking should be evaluated by a professional.
Tools You Might Need
You don’t need a ton of fancy equipment to check for signs of a sinking house. Here are a few basic tools that can come in handy:
- Level: A level is essential for checking if walls and floors are plumb and level.
- Tape Measure: A tape measure can be used to measure the width of cracks and the dimensions of rooms.
- Marble: A marble can be used to check for sloping floors.
- Binoculars: Binoculars can help you get a closer look at hard-to-reach areas.
- Flashlight: A flashlight is useful for inspecting dark areas, such as the foundation.
- Notebook and Pen: Keep a notebook and pen handy to record your observations.
- Camera: Take photos of any cracks or other issues you find.
When to Call a Professional
While this guide can help you identify potential problems, it’s important to know when to call in the experts. Here are some situations where you should consult a professional foundation repair company or structural engineer:
- Multiple Signs: If you notice several of the signs mentioned above (cracks, sticking doors, sloping floors, etc.), it’s time to call a professional.
- Large Cracks: Any crack that is wider than 1/4 inch should be evaluated by a professional.
- Growing Cracks: If you notice that cracks are getting bigger over time, it’s important to have them inspected.
- Bowing Walls: Bowing or bulging foundation walls are a serious issue and require immediate attention.
- Unsure: If you’re not sure whether or not your house is sinking, it’s always best to err on the side of caution and get a professional opinion.
A professional can assess the situation, identify the underlying cause of the problem, and recommend the appropriate repairs. They can also provide you with a written report that you can use for insurance purposes or when selling your home.
Potential Repair Methods
If your house is sinking, there are several potential repair methods that can be used to stabilize the foundation. The best method will depend on the specific situation and the underlying cause of the problem. Here are some common repair methods:
- Slab Jacking: This involves pumping grout or foam under the slab to lift it back into place.
- Piering: This involves driving steel or concrete piers into the ground to support the foundation.
- Underpinning: This involves extending the foundation deeper into the ground to provide additional support.
- Soil Stabilization: This involves improving the soil around the foundation to prevent further settling.
- Drainage Improvements: Improving drainage around the foundation can help prevent water damage and soil erosion.
Important Note: Foundation repair can be expensive, so it’s important to get multiple quotes from reputable contractors before making a decision. Be sure to ask for references and check online reviews.
Preventative Measures
While you can’t always prevent a house from settling, there are some things you can do to minimize the risk:
- Maintain Good Drainage: Make sure that water drains away from your foundation. Clean your gutters regularly and ensure that your downspouts are properly positioned.
- Avoid Overwatering: Overwatering your lawn or garden can saturate the soil around your foundation, leading to settling.
- Plant Trees Carefully: Avoid planting large trees too close to your house, as their roots can damage the foundation.
- Regular Inspections: Regularly inspect your foundation for cracks and other signs of damage. Catching problems early can prevent them from becoming more serious.
