Structural Damage

What it is

Structural damage is compromise to the load-bearing elements of a house: the footings and foundation, the floor joists and beams, the wall studs and headers, the subfloor, and the roof rafters and trusses.

The five structural things I look for on a walkthrough: cracked foundations, sloping floors (mid-hump, mid-dip, or a roller coaster feel underfoot), squishy floors, rotted walls, and collapsing roof elements. I’ve literally bought a house that had no footings — couldn’t figure out why it wouldn’t stop sinking, then discovered there were no footings underneath it at all. I mean, that stuff exists, guys.

A structural issue that scares off most buyers means the buyer pool shrinks dramatically. When the buyer pool gets smaller, you get a better deal. If you can take the scary out of it, fix the structural, make people who lack vision be able to see the vision — you put yourself in a strong position. That’s why I actually like structural jobs in some ways.

Why it matters

Structural damage scares new flippers into walking away from deals they should buy, and into buying deals they should walk away from. Both failures come from the same root: not knowing what structural actually costs.

A sloping floor reads like a nightmare until you realize a few piers fix it. Real money, but not a disaster number. A rotted band joist reads like a cosmetic issue until you realize the whole perimeter needs to come out.

The way to break the fear is to break the damage into discrete tasks. Sistered joist. Replaced beam. Sill plate swap. Footing piers. When you can quote the job line by line, it stops sounding like a disaster and starts sounding like a scope of work.

There’s code to know: floor joist notching has limits. Roughly 30% depth max, only in certain spans. Plumbers over-notch all the time because they need to run a drain line and the joist is in the way. That fails inspections and costs rework money. Also: pressure-treated wood is required anywhere wood touches masonry, galvanized nails are required in crawl spaces. Small rules, expensive fails.

How it shows up

Most structural problems trace back to a water intrusion source visible from the outside: negative drainage, pooling, saturated soil. Fix the source, then open up enough to assess what the water reached. Bleeding gets addressed before any structural repair. If water is still getting in, rebuilding structure is just setting up the next round of rot.

One rule that has saved me significant money on more than one deal: keeping at least one wall standing preserves the house as “existing structure” under most building codes, which avoids the full new-build requirements. Tear everything down and you’re building new. Leave one wall standing and you’re renovating. That rule alone is worth six figures on the right project.

When you’re unsure whether a wall is load-bearing, stop. Get a structural engineer or a licensed GC on site before you swing. A $500 consultation is cheaper than a bowed ceiling joist.
