Pier and Beam Foundation Repair in Plano
Pier and beam homes are the minority in Plano, found mainly in older blocks near downtown and in some additions. They are repaired from the crawl space: shims, supports, beams and moisture control.

Where pier and beam shows up in Plano
Plano's early development was concentrated around the old downtown, and houses from that period were built the way most of Texas built before slabs became standard: on piers, with a wood floor above a crawl space. Some of those homes remain, restored and valued, and a number of later additions and rooms were also built over crawl spaces.
Their owners tend to care about what's original, and that changes the repair. The aim is usually to stabilize and level the structure while preserving as much of the existing framing as possible.

What a crawl space inspection covers
The technician enters the crawl space and checks the piers and their footings, the beams that span them, the joists above and the sill plates along the perimeter. Wood is probed for softness. Shims are inspected for compression or slippage. Moisture, standing water, bare soil and ventilation are noted.
A set of elevation readings on the floor above shows where the house sits high or low. Photographs of the crawl space come with the report; most owners have never seen it, and the images often explain a problem immediately.

Leveling and strengthening
Leveling raises the low parts of the floor system and fixes them in place on new shims or adjusted piers. It's done gradually, in stages, so that walls, doors and plumbing follow without cracking. Where a floor sags between supports, the remedy is a new pier and a short beam under the span.
Older homes seldom need perfectly level floors, and forcing them level can crack plaster and bind doors. The inspector should explain the target and the reasoning, and propose a result that balances improvement against risk.

Wood, termites and moisture
A lot of what looks like a foundation problem in a pier and beam house is actually a wood problem. Moisture rots sills and joists, and termites feed on damp wood. Replacing damaged members is routine, but only if the inspection finds them.
Longer-lasting repairs address the cause of the moisture: clearing vents, adding a vapor barrier over bare soil, correcting drainage and fixing plumbing leaks beneath the house.

Additions over a crawl space
A family room or master suite added over a crawl space to a slab house forms a joint between two different foundations. The addition may settle differently, and cracks open at the connection. Supporting the addition with its own piers and adding a flexible joint is the usual remedy, rather than lifting the whole house to match.

Things to ask before work begins
How many supports will be added or adjusted? What are the shims made of? Will any wood be replaced, and how much? How will the crawl space access be restored? What does the company expect the readings to be afterwards, and why? Clear answers separate a careful proposal from a vague one.

Living with a pier and beam house
Owners of pier and beam homes who maintain them well rarely face big repairs. A glance into the crawl space once or twice a year, a clear path for water away from the house, working vents and a dry subfloor are most of what it takes. Plumbing leaks beneath the house, which are easy to miss, deserve attention at the first sign of dampness.
When a house does need work, the cost is usually far lower than for a slab repair of comparable scale, which is one reason many owners prefer to keep the original system.
09 — Detail
Choosing shims and supports
Modern repairs use steel or composite shims and adjustable supports instead of the wood wedges many older houses started with. They resist compression and moisture and are easy to adjust again later. Ask what's being used and what warranty applies to the supports and to the work itself.

What it costs
Re-shimming and resetting piers usually costs less than slab piering. Costs rise with the number of new supports, wood replacement and access difficulty.
Questions
Pier & Beam Foundation Repair — asked and answered
Why do my floors feel bouncy?
Usually because a span between supports is too long or because wood has weakened. Adding a pier and beam under the span often solves it.
Can a pier and beam house be preserved while repaired?
Yes. Repairs are normally conservative and keep original framing wherever it is sound.
Do I need a vapor barrier?
If the crawl space is damp or has bare soil, a barrier helps protect the wood. The inspection will say how damp it is.
How long does a leveling job take?
Often a few days, depending on the number of supports and any wood replacement.
