Pier and Beam Foundation Repair in Montgomery, AL
Many older homes in Montgomery, Alabama were built on pier and beam foundations, also
called raised foundations. A series of masonry piers or wood posts supports a grid of beams
and floor joists, creating a crawl space beneath the house. While this design offers easy access
to plumbing and wiring, it is vulnerable to settlement, wood rot, and pest damage. Pier and
beam foundation repair in Montgomery restores the support system and levels your floors
without the need for a full rebuild.
Common Problems in Montgomery’s Raised Foundations
Pier and beam foundations fail for three main reasons in Montgomery, AL. First, the piers
themselves—often made of brick, concrete block, or untreated wood—can sink into the clay
soil when it softens after heavy rain. Second, moisture in the crawl space causes wood beams
and joists to rot, losing their load‑bearing capacity. Third, termites or carpenter ants can hollow
out wooden supports, leading to sudden collapse. You might notice springy or sagging floors,
doors that no longer latch, or cracks where interior walls meet the ceiling. Montgomery
Foundation Repair Co inspects every component, from the soil under the piers to the condition
of each floor joist.
Replacing Sunken or Rotated Piers
When a masonry pier sinks, the foundation above it tilts, creating a dip in the floor.
Montgomery Foundation Repair Co installs adjustable steel piers or helical piles next to the
failed masonry pier, then transfers the beam load to the new support. In many cases, we can
leave the original pier in place as a backup. For wood posts that have rotted at ground level,
we replace them with pressure‑treated 6x6 posts or galvanized steel adjustable jacks. All new
piers are set on precast concrete footings or small spread footings that distribute weight over a
larger area, reducing the risk of future settlement.
Leveling Floor Joists and Sistering Rotten Wood
Once the piers are stable, we turn our attention to the floor system. Using laser levels and
hydraulic jacks, Montgomery Foundation Repair Co lifts sagging floor joists back to level. If a
joist has minor rot on the end, we may cut back the damaged section and “sister” a new joist
alongside it, bolting the two together. For widespread rot, we replace entire sections of the
floor system. Finally, we install bridging (solid blocking or metal cross braces) between joists to
distribute loads evenly and reduce floor bounce. The result is a solid, level floor that feels like
new.
Integrating Crawl Space Moisture Control
Repairing the structure without addressing crawl space moisture is a losing battle. After
completing pier and beam repairs, Montgomery Foundation Repair Co recommends installing a
vapor barrier over the exposed soil, sealing crawl space vents, and adding a dehumidifier.
These steps keep humidity below 60 percent, preventing the wood rot that caused the original
problem. We also check that gutters and downspouts direct water at least 10 feet from the
foundation. A dry crawl space ensures your repaired foundation lasts as long as the rest of the
house.
Frequently Asked Questions
How much does pier and beam foundation repair cost in Montgomery?
Simple leveling with a few replacement piers may cost $3,000 to $6,000. Extensive work involving many joists, beams, and crawl space encapsulation ranges from $10,000 to $25,000. Montgomery Foundation Repair Co provides free estimates.
Can I add a vapor barrier myself after repairs?
You can install 6‑mil plastic sheeting, but professional encapsulation uses heavy 12‑ or 20‑mil reinforced liner, sealed seams, and wall attachments that create a true moisture barrier. Mistakes by DIYers often lead to mold growth behind the plastic.
How long does pier and beam repair take?
Most projects take two to five days. Large homes with extensive rot may require one to two weeks if structural lumber must be custom cut and delivered.
Will repairing the foundation fix my uneven floors?
Yes, when combined with proper lifting and shimming. Montgomery Foundation Repair Co uses hydraulic jacks to raise sunken floor joists to level, then installs permanent supports. Your floors should feel flat and solid after completion.
