Foundation inspections in Sugar Land
A free look from a repair company, or a paid report from an engineer? What each gives you, and which level of investigation to ask for.
Two kinds of visit
This Old House notes that foundation repair companies usually inspect for free, and lists a structural engineer's report at $500 to $1,000 and a soil engineering report at $500 to $3,000. The free visit tells you what the company would sell you. The paid report comes from someone who isn't selling a repair, and it is the one to have if a quote runs into five figures.
Three levels, from the Texas guidelines
The Texas Section ASCE guidelines describe three levels of foundation investigation, each building on the last:
| Level | Adds | When it fits |
|---|---|---|
| A | Interviews, document review, a visual walk-through and notes on what's affecting the foundation | Deciding whether anything needs a closer look |
| B | Measured relative floor elevations, drawn to scale, compared with tolerances for tilt and deflection | Deciding whether to repair, and where |
| C | Extra work such as soil testing, plumbing tests, material testing, a tree survey, a detailed damage survey and post-tensioning cable testing | When the cause isn't clear, or the slab is post-tensioned |
Level C is the one that fits a lot of Sugar Land houses: big trees, post-tensioned slabs and plumbing under the concrete all appear on its list.
What the numbers mean
The guidelines treat a tilt over 1 percent as usually noticeable, and use the building code's L/360 ratio for deflection across the whole foundation. They warn against reading too much into small dips over short distances, less than about 20 feet. A Level B report should show where the floor sits against those yardsticks.
Check the engineer
The state's engineering licensing board keeps a searchable roster, so check the engineer's license there, and ask if they do any paid work for the company quoting the repair. A report should name the level of investigation, show the elevation drawing if one was made, say whether repair is needed now or monitoring is enough, and list drainage, trees or leaks noticed on site.
Buying or selling
A report and a record of floor elevations are useful to a buyer, and so is a letter of substantial completion if a repair was done. The guidelines describe both the post-repair elevations and the completion letter. Keep them with the permit from the city.
