Settlement In A Home At Any Age Is Not Good

All sagging floors and unlevel floors are caused by inadequate load bearing capacity whether it is due to the wood framing of the floor weakening from moisture and wood destroying fungi, from weak footings that support the CMU piers or a settling foundation.

Settlement in a home at any age is not good and while it may be somewhat common for older homes, it is not good for the health and value of the home.

Most floors in crawl spaces are being supported first by the homes foundation, the concrete piers, then by the main carry beams, and then by the floor joists. The load bearing capacities of these 4 building components also go in this order generally.

The concrete masonry piers can hold more weight than the middle-span of the beam and the middle-span of the main carry beam can hold more weight than the middle-span of the floor joists.

If the home is on soft ground, there are an undermined foundation footing, or the ground shrinks and swells then there can be foundation settlement. If the individual footers for the piers are too weak, the pier will sink.

If the weight over the top of the middle span of the main carry beam is too much and the wood has weakened from wood moisture and fungus, you will see your floors settling and sagging.

The common cause of uneven floors

Crawl space moisture is a common cause of uneven floors. When the wood framing that supports your floors becomes moist, it gets weakened. A common sight during our inspections is ‘compression’ of the floors joists and beams. With crawl space moisture, the wood framing can compress under the heavy weight of the home.

Basically, unlevel floors and doors can be caused by any combination of failing foundation, inadequate structure, an improperly designed home, or a moisture-damaged structure. Fixing these problems requires a professional crawl space repair contractor, specific products and methodologies, and is not recommended for a general contractor or jack of all trades.

Here’s the good news though. It is very possible to get a correction. We can install additional crawl space jacks, supplemental beams, or steel foundation push piers that can make your floors more level, fix doors & windows that are sticking, and permanently stabilize your floors.

Causes of Structural Issues

  • Inadequate Load Bearing: Problems occur when the foundation, footings, or wood framing cannot support the home’s weight.
  • Moisture & Fungi: Crawl space moisture weakens wood, leading to “compression” where joists and beams flatten under the home’s weight.
  • Soil Instability: Settlement can be triggered by soft ground, undermined footings, or soil that shrinks and swells.
  • Design Flaws: Overly long spans on floor joists and girder beams often lead to sagging and misalignment.

Common Warning Signs

  • Uneven or Sagging Floors: A direct result of weakened support components or a shifting foundation.
  • Sticking Doors & Windows: These functional issues are secondary indicators that the home’s frame has shifted out of alignment.
  • Visible Damage: Professionals often look for compressed wood or sinking concrete masonry (CMU) piers during inspections.

Professional Solutions

  • Structural Reinforcement: Adding supplemental beams or repairing damaged components like sill plates, subfloors, and girder beams.
  • Adjustable Support: Installing crawl space jacks to provide stabilized, supplemental lift.
  • Foundation Piers: Utilizing steel push piers to permanently stabilize and potentially level a settling foundation.

Crawl Space Issues And Solutions

  • Sagging floors are caused by moisture and wood destroying fungi.
  • Rotten wood causes structural issues, which need to be fixed.
  • Long spans on floor joists & beams often cause uneven floors & sticking doors.
  • Settlement in homes is not good for health and value.

Common Questions About Crawl Space Issues

Q: What causes uneven floors and sticking doors? A: Inadequate load bearing capacity due to moisture and wood destroying fungi, weak footings, or a settling foundation. Long spans on floor joists & girder beams often cause uneven floors & sticking doors.

Q: How can crawl space issues be corrected? A: By installing additional crawl space jacks, supplemental beams, or steel foundation push piers. Wood repairs to floor joists, girder beams, sill plates, & subfloor are often needed.
