Common signs

Signs your floor supports may need attention

  • Sagging or dipping floors

    Low spots you can see or feel, often in the middle of a room or hallway.

  • Bouncy or soft areas

    Floors that flex or feel spongy when you walk across them.

  • Doors that stick or swing

    Doors that no longer latch or drift open on their own.

  • Damaged posts

    Posts that are cracked, leaning, rotted or crushed at the top or bottom.

  • Posts on dirt or loose blocks

    Supports that were never set on a proper footing.

  • Split or sagging beams

    Beams that are cracked, damp or visibly bowed between posts.

Uneven floors have many possible causes. A sloping floor doesn't automatically mean a post or beam has failed. That's what the inspection is for.

How crawl space supports hold up your floors

In most crawl space homes, the floor rests on joists, the joists rest on beams, and the beams are held up by posts sitting on concrete footings or piers. When one of those pieces is damaged, missing or settling, the floor above can sag or feel soft.

Post and beam repair addresses that support system directly. Depending on what we find, that can mean replacing deteriorated posts, adding support where it's lacking, or correcting what a post is sitting on.

  • Check posts, beams and footings for damage or settling
  • Replace damaged posts and add support where needed
  • Secure new supports with proper hardware
  • Point out moisture problems that caused the damage

Moisture is often part of the story

Behind every rotted post and beam is a hidden history of trapped moisture. You don't have to guess where the water is coming from, and you shouldn't have to worry about the fix.

Our team steps in to trace the moisture to its source, eliminate the root cause, and completely rebuild the damage. We take care of everything, delivering the lasting repairs and protection you need to feel completely safe in your home again.

Post and beam, floor leveling and foundation work

Post and beam repair fixes the wood supports and their connections. Floor leveling brings sloping floors back into line, often using that same support work. Foundation repair deals with the foundation walls and footings. When your home needs more than one, we build them into a single plan.

Questions

Post and Beam Repair questions

What causes posts and beams to fail?

The most common causes are long-term moisture and rot, posts set on soil or loose blocks, undersized supports, settling footings and older repairs that were never done right. Whatever the cause, we repair it properly so your floors are solidly supported.

Is a sagging floor always a post or beam problem?

Not always. Sloping floors can also come from settling, damaged joists or foundation movement. Our inspection pinpoints the real cause, so you get the right repair the first time.

Do you replace posts or add new ones?

Both. We replace damaged posts, add new support wherever your floor needs it, and secure everything with proper hardware. You'll know exactly what we're doing before we start.

Will my floors feel solid afterward?

Yes. Our goal is solid, properly supported floors you can feel the difference in. If your floors also need leveling, we'll build that into the same plan.

Is it safe to wait?

Support problems get worse over time, not better, so it's best to have them looked at early. If you notice floors changing quickly, new cracks or a post that has shifted, call us right away.
