Most Common Signs of Foundation Problems
Foundation problems cause some of the most expensive home repairs for many homeowners. On average, foundation repairs cost anywhere from $5,000 to $7,000 or more if the issues damage other sections of the house.
Identifying foundation problems on your own can be tricky since the signs often appear like minor cosmetic problems. For instance, some cracks in the wall are just superficial, while others signify significant shifts in elevation.
Many foundation problems have subtle warning signs and may go unseen for weeks to months. If you don’t know what house foundation problems look like, you’ve come to the right page! We’ll go over the most common warning signs of foundation troubles below.
Exterior Wall Cracks
If your home’s exterior walls have cracks, please pay attention to them. Wall cracks resulting from natural house settlements aren’t dangerous in most cases. You can fix minor cracks easily with some plaster and paint. But larger wall cracks often indicate serious foundation issues. They include:
- Cracks that expand over time
- Noticeable cracks that are wider than 0.25”
- Huge diagonal cracks around the corners of doorframes
- Uncannily long horizontal cracks
If a drywall crack keeps reappearing after plastering it over, your foundation might have an underlying issue.
Cracks in the ceiling may indicate a building has underlying foundation problems. The ceiling structure can shift even with the least significant foundation settling, causing ceiling cracks. Cracks extending across the ceiling’s entire length or matching vertical cracks can signify serious foundation troubles.
Sinking Ground around the Home
Walk around your house if you suspect something’s wrong with its foundation. If you notice any sinking in the ground around your home, this could signify foundation damage. Sinking around the home can result from serious water drainage or leakage problems.
Weeds Close to the Foundation
Most homeowners don’t like weeds growing so close to their home’s foundation.
If they’re simply scattered around, it’s nothing to worry about. However, if they’re clustered and growing near the foundation line, this might indicate that too much moisture around the foundation is potentially causing problems.
It also goes without saying that if you notice weeds sprouting from the foundation line, this means the foundation itself has cracks.
One of the most evident signs of foundation damage is uneven flooring. This problem is also quite common in older houses, so that doesn’t mean you overlook it. Signs of an uneven floor can include buckling floors, squeaky boards, or a depression at the center of a room.
Uneven floors may be due to foundation problems, termite damage, poor wood quality, and moisture damaging the wood under the floor. You can identify the slope by spilling liquid on the floor. If the liquid flows in one direction, you’ve got a damaged foundation.
Since it’s difficult to determine the exact cause of uneven floors in your home, you must call a foundation repair professional to fix the issue.
Tile Floor Cracks
If your home’s foundation has problems, your tile floors should be able to confirm that. If you notice unexplained cracks in your floor tiles, a foundation issue is highly likely to be the root cause. Therefore, be sure to call a professional to examine the issue further and find a solution.
Sticking Doors and Windows
If your foundation moves even slightly, you may have trouble opening or closing doors and windows. This is because the slight movement of the foundation makes frames around the doors and windows also shift.
Another warning sign of foundation troubles is when a chimney moves too much. It may collapse completely, putting your family members in danger. If your chimney looks somewhat out of kilter, contact a professional to repair and stabilize it.
If your exterior or interior walls have started to bow, it could indicate that your foundation is shifting. However, you shouldn’t confuse a paint blister with bowing. A painter blister can indicate water or heat damage to your drywall and paint. While this problem may require urgent attention, it’s got nothing to do with foundation problems.
Musty Smell in the Basement
A musty smell in your crawl space and basement corners can be a signal that your foundation’s in trouble. The smell itself is normally mildew and might be the result of leaking basement walls.
A smelly basement could be due to plumbing issues, but it may also be due to moisture from outside seeping in through the cracks in the foundation.
Standing Water Under the Home
Rainwater must be directed away from your home through gutters, well-directed downspouts, as well as drainage systems. Poor drainage often collects water underneath a house, leading to foundation problems.
Windows and Doors Coming Off Walls
Windows or doors tearing away from walls is another subtle sign of foundation troubles. That can cause serious cracks and damage. Be aware of gaps beneath doors, crooked door frames, and window frames splitting from surrounding trim.
Doors and Windows Getting Stuck or Not Latching
It’s usually easy to fix a stuck window or door, but that’s not always a sign of a minor issue.
If all the windows or doors get stuck when you try to open or close them, your house could have foundation problems. This happens when the foundation starts to sag, meaning that the house isn’t square anymore.
Its drainage system is one of the main parts of a house that requires regular maintenance. If you notice a minor drainage issue, it could be part of a severe issue.
Drainage issues might result from leaking pipes or clogged major sewer lines. These problems might lead to an imbalance in the terrain due to soil expansion or contraction, seriously affecting the entire foundation of the home.
Damp Crawl Space
Dampness in a home’s crawl space is a good sign that you already have foundation problems or soon could.
If your crawl space has puddles of water, that’s not a good sign, but the water alone won’t damage your home. Moisture causes mold, rot, and energy loss and attracts household pests.
Cracked, warped, or buckled siding can be due to moisture or other problems, including severe structural issues with your house’s foundation.
If you notice gaps between planks or warped siding, it’s a telltale sign that your foundation has issues. A wood cladding home usually has evidence of a foundation problem. There will be spaces between where siding lengths join and where the siding extends beyond the bottom and top.
