A deck is only as steady as its footings.
Helical deck piers screw galvanized steel down past the surface clay that heaves and shrinks with the seasons, so your deck stands on ground that has stopped arguing with the weather.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What to know about helical deck piers, and when it's the right call.
A helical deck pier works like a screw driven into wood: the helix plates convert rotation into downward pull, drawing the shaft through the loose, moisture sensitive surface soil into deeper ground with real bearing capacity. The drive head records torque as it turns, and since torque tracks soil resistance, the crew reads capacity in real time and keeps advancing until the pier meets the target for the loads it will carry. A steel cap or bracket then connects the pier to the deck post or beam. From that point the deck's weight travels straight down the shaft to soil that does not shrink and swell with the seasons, which is exactly what the old shallow footing could not offer. Because the pier bears immediately, there is no waiting on concrete, and because the shaft is galvanized, it resists corrosion below grade for the long haul.
The symptoms that usually lead to helical deck piers are on the foundation repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install helical deck piers.
Free evaluation of footings and framing
We measure post plumb and deck elevations, check the existing footings, and separate footing settlement from framing failure, because steel under a bad beam fixes nothing. You get the findings in writing.
Pier layout and sizing
Pier locations and helix configuration are matched to the deck's loads, the soil, and the access. Compact drive equipment reaches tight backyard spots.
Drive the piers, log the torque
Each galvanized pier is rotated into the ground while the crew logs torque and depth, advancing until the readings prove capacity for the load that pier will carry.
Connect and level
Steel caps or brackets tie the piers to posts and beams, and the deck is brought toward level as the load transfers to the piers.
Clean up and verify
The site is cleaned and final elevations are checked against the starting measurements, so you can see the correction, not just take our word for it.
Anchored to solid ground.
Steel piers screw down through the unstable soil under your home and lock into deep, solid ground. Your home's weight then rests on that, not on shifting clay.

Care and expertise from a team that's been doing this since 2011.
When the fix is helical deck piers, the installer matters as much as the method. Dalinghaus crews handle foundation, concrete, and crawl space work across California, Arizona, and Nevada, and nothing else.
Foundation repair, concrete leveling, and crawl space repair are our entire focus. Not a sideline.
More than 2,000 projects on the clay and desert soils of California, Arizona, and Nevada since 2011.

Warranty terms come in writing with every proposal, and the terms that apply to your job are stated in that job's paperwork. Ask your project specialist during the free evaluation.
Answers to common questions about Helical Deck Piers.
Don't see your question here? Our team is happy to help. Reach out anytime.
Because a bigger pad in the same moving soil is still a pad in moving soil. Shallow footings sit in the zone where clay shrinks and swells with the seasons, which is what tilted the originals. Helical piers pass through that zone entirely and bear on deeper, stable ground, and each one proves its capacity by torque before it carries anything.
Other foundation repair solutions we install.
Every solution is engineered for a specific soil profile and failure mode. Browse the full toolkit.
Carbon Fiber Reinforcement
Carbon fiber straps bond to a stressed foundation wall and refuse to stretch, so the wall that was slowly losing to soil pressure simply stops moving.

Deep Foundation Systems
Deep foundation systems skip the surface soil entirely and stand your structure on strata that stopped moving long ago, with each element proving its capacity as it goes in.

Epoxy & Polyurethane Crack Injection
Epoxy welds a structural crack back into one piece; polyurethane chases water through a wet one and seals it shut. Choosing correctly between them is most of the repair.

Foundation Underpinning
Underpinning does not patch a settling foundation, it reaches underneath and hands the load to soil that stopped moving long before your house was built.

Grout Injection (Chemical Grouting)
Chemical grouting injects grout directly into weak, loose ground, bonding the particles into a soil that can finally carry what sits on it, no excavation required.

Helical Piers
Helical piers carry your home past the unstable clay to load bearing strata, and the torque reading on every pier proves it before we transfer a pound of weight.
