What Homeowners Often Notice First
Each symptom can have more than one cause. These are common observations, not a diagnosis — an on-site evaluation is what confirms what is actually happening beneath your home.
Missing or Inadequate Existing Piers
What you may see: Gaps in the support layout, or piers that no longer reach the beam.
Possible causes: An original installation that fell short of specification, or piers lost to damage over time.
Cracked or Deteriorating Blocks
What you may see: Existing blocks show cracks, spalling, or crumbling surfaces.
Possible causes: Load stress, freeze-thaw cycling, or age-related material breakdown.
Shifting or Tilting Stacks
What you may see: Block stacks are no longer vertical or centered under the beam.
Possible causes: Footing movement or lateral shift from ground or anchor movement.
Footing Concerns Beneath Piers
What you may see: Pads are sinking, eroding, or appear absent beneath existing piers.
Possible causes: Soil-bearing loss or inadequate original footings beneath the home.
Moisture at the Pier Base
What you may see: Standing water or saturated soil around pier footings.
Possible causes: Drainage problems or a high water table undermining the bearing base.
New Home Setup Needs
What you may see: A newly delivered home requires pier installation to specification.
Possible causes: Initial setup following manufacturer instructions and applicable requirements.
What a Block Pier Supports and Why Design Matters
A block pier is a stacked concrete masonry assembly that transfers the chassis load down through the blocks and into a footing pad or bearing surface in the soil. Its job is to hold the home level at the height the manufacturer specified. The blocks, the footing, the shimming, and the spacing all work together — change one and the others are affected.
Pier configuration — block size, whether reinforcement or mortar is used, spacing, and count — depends on the manufacturer's installation instructions, applicable regulations, and any engineered design for the home and site. There is no universal stacking pattern, pier count, or spacing that applies to every home.
Block piers are one support option among several. Adjustable jack stands, engineered pier systems, or other approved assemblies may be appropriate depending on the home and site. We do not recommend block piers as a default for every installation.
Understanding Loads, Bearing and Pier Locations
An evaluation reviews the home's weight and support requirements, the soil bearing capacity, drainage, and access. Where the manufacturer's instructions or engineered plans are available, they guide the layout; where they are not, the evaluation works from the home and the site as they are.
We never publish universal block dimensions, load ratings, stacking patterns, or spacing. Those depend on the home model, the soil, and any applicable design — and are determined for the specific installation, not prescribed from a form.
A cracked existing block may be replaceable; a footing that has failed may need rebuilding before a new pier sits on it. The evaluation distinguishes the pier from the base beneath it, because the two fail differently and need different work.
Block Piers Versus Other Approved Support Assemblies
Block piers may be appropriate where soil bearing and drainage support them; in other conditions, a different approved assembly may fit better. The choice depends on the home, the soil, and the applicable requirements — not on a default preference.
Footings, pads, and drainage beneath block piers matter as much as the blocks above. A pier installed on bare or saturated soil, or on a washed-out footing, may settle again. Site preparation and drainage are part of the conversation.
For a new home, installation follows the manufacturer's instructions and any applicable state set-up requirements; for an existing home needing support changes, the scope is determined from the current condition. We do not assume the same specification applies in both cases.
Coastal Factors That Can Affect Support Systems
Wilmington sandy soils can drain quickly but shift under load and saturation, and a high water table in some areas can keep the footing base wet. These conditions affect whether a block pier and its footing will hold, and they are evaluated per parcel rather than assumed.
Heavy rainfall and poor surface drainage erode footing material, and salt air can affect any metal connectors or hardware nearby. We consider coastal exposure only as it is relevant to your specific site.
Salt-Air Exposure
Proximity to the coast accelerates corrosion of galvanized tie-down straps, buckles, and auger rods — a concern from Carolina Beach to Oak Island.
High Water Tables
In some low-lying settings, a shallow water table can undermine pier footing stability and keep the crawlspace damp.
Sandy & Variable Soils
Coastal sandy soils drain fast but shift under load and saturation, causing uneven pier settlement over time.
Rainwater & Drainage
Heavy tropical rainfall and poor surface grade direct water beneath the home, keeping piers and the vapor barrier wet.
Floodplain Mapping
Flood exposure is parcel-specific. New Hanover, Brunswick, and Pender counties each have mapped zones; verify your parcel at flood.nc.gov/ncflood.
Wind Exposure
Open coastal exposure differs from sheltered inland lots. Wind-restraint needs depend on the home's HUD wind zone and the site.
Flood exposure is parcel-specific. The North Carolina Flood Information Center is a neutral resource for verifying floodplain mapping. We do not assert a fixed flood elevation or permit determination for any property.
How a Leveling Discussion Begins
Every project starts with your description and your property's specifics — not a quote.
Describe Your Concern
Tell us what you are seeing — sloping floors, sticking doors, loose straps, skirting gaps, or moisture.
Identify Structure & Site
Share the home type and your location or closest community so we can consider local conditions.
Review Visible Symptoms
Safe photos from outside the crawlspace help us understand the situation before any visit.
Determine Next Steps
We decide together whether an on-site evaluation, a specialist, or a permit review is warranted.
Discuss Scope & Estimate
Only then do we talk about potential scope, timing, and cost — based on your actual property.
We do not promise a fixed turnaround, exact pricing, or a guaranteed outcome. Scope follows an honest review of your property.
