Crawl space repair in Murfreesboro
Most people never see the part of the house that holds up their floors. In a crawl space house it is a few dozen short columns and one or two long beams, standing on clay in the dark.
The parts
What is under the floor
Around the edge runs the foundation wall, usually block or brick on a concrete footing. Down the middle run one or more main beams, often called girders. They rest on piers: stacks of block or brick, each on its own small pad. Joists cross from the wall to the beam, and the subfloor is nailed on top of them.
Every piece depends on the one below it. When a pier loses half an inch, the beam drops, the joists follow, and a dip appears upstairs along the line of that beam.
Typical findings
What inspectors tend to find
Supports
- Piers that have sunk or tipped where the clay under their pads softened.
- Piers spaced too far apart for the beam they carry.
- Wooden shims and blocks on top of piers that have crushed or rotted.
- Temporary jacks from an earlier fix, standing on bare soil or a loose block.
Wood
- A beam that has sagged between piers or decayed where it meets the wall.
- Joists softened by years of damp, or cut into for pipes and ducts.
- Insect damage, which a pest control firm treats before any structural repair.
- Subfloor that has delaminated under a bathroom or kitchen leak.
Local conditions
Why crawl spaces here stay damp
The biggest storms in Middle Tennessee tend to come between December and March, with thunderstorms through spring and summer. The soil is thin clay over limestone, so water has little depth to soak into before it meets rock. Low ground under a house can stay wet long after the yard looks dry.
In summer, warm humid air drawn in through the foundation vents meets cooler wood and ductwork and leaves moisture on them. None of this is dramatic. It works over years, which is why a crawl space problem tends to arrive as a floor that slowly got worse.
Repairs
What a proposal may list
New or added supports
Adjustable steel posts or rebuilt block piers, each on a properly sized concrete pad, placed to shorten the distance the beam has to span.
Beam and joist work
A new length of beam beside or in place of a failed one, and new joists fastened alongside weakened ones.
Lifting
Raising the floor toward level in small steps with screw jacks, watching doors and drywall upstairs as it goes.
Keeping it dry afterwards
Grading, gutter and drain corrections, a ground cover of heavy plastic, or full lining of the space. Ask which of these the company does itself and which it leaves to others.
Before the visit
Make the inspection easy
- Find the access hatch and clear what is stacked in front of it.
- Mention standing water, a sump pump, or a past plumbing leak.
- Say which rooms dip or bounce so the inspector knows where to look underneath.
- Keep pets out of the way of an open hatch.
If there is standing water or exposed wiring under the house, leave going in to the person who does it for a living.
Questions
About crawl space repairs
Is crawl space repair the same thing as encapsulation?
No. Repair deals with what holds the floor up. Encapsulation lines the space with a sealed membrane to control moisture. A house may need one, the other, or both, and they are priced separately.
Can supports be added without lifting the floor?
Yes. A company can stabilise the floor where it is, which avoids disturbing finishes, or lift it as well. Ask which one its price covers.
My crawl space smells musty. Does that mean the structure is damaged?
Not by itself. It means there is moisture, and moisture over time is what harms wood. A look underneath settles whether anything has softened yet.
