Introduction: The Backbone of Your Basement
Lally columns — the round, steel-filled support posts commonly found in basements — are essential for holding up your home’s floor joists and beams. When they fail, the stability of your floors and walls above can be severely compromised.

In New Hampshire and across New England, older homes in towns like Exeter, Kingston, Hampton, Dover, Stratham, Portsmouth, and Brentwood often rely on Lally columns that were installed decades ago. Many of these columns were constructed with steel pipes filled with concrete or older materials that, over time, rust, corrode, or settle, particularly when exposed to moisture, frost heaves, and shifting soil.

While a sagging floor or a bowing beam might seem minor, a failing Lally column is a serious structural issue that demands professional attention.

Signs of Failing Lally Columns
Homeowners should be alert to the following warning signs:

• Sagging floors above a basement support beam.
• Bowed or cracked beams resting on the columns.
• Columns that lean, tilt, or show rust at the base.
• Creaking or popping noises when walking on upper floors.
• Cracks in walls above the column line caused by uneven load distribution.
• Gaps between the floor and beam where the column no longer makes full contact.

If you live in older New England homes, particularly in Plaistow, Seabrook, North Hampton, or Haverhill (MA), these symptoms are common due to decades of frost cycle stress and moisture intrusion.

Why Failing Lally Columns Are Dangerous
A Lally column is not just a support — it is literally holding up your home. Ignoring a failing column can lead to:

• Sagging or uneven floors throughout the home.
• Cracked beams and joists, which can compromise structural integrity.
• Water intrusion if moisture has caused rust or base rot.
• Full structural failure in extreme cases, especially when multiple columns are compromised.

Even a small shift in one column can transfer enormous stress to surrounding beams and floors, creating hidden damage that grows over time.

Why DIY Fixes Don’t Work
Some homeowners attempt to “shim” a failing Lally column with blocks or stack additional supports. This is extremely dangerous:

• Temporary supports do not distribute weight properly.
• Rusted or bent steel cannot be corrected by adding wood blocks.
• Incorrect adjustments can accelerate sagging or cause sudden collapse.
• Proper repair requires lifting, stabilizing, or replacing structural beams — work that cannot be done safely without experience and professional equipment.

Professional Solutions for Failing Lally Columns
At 603 Basement Solutions, we specialize in assessing and repairing failing support beams and Lally columns in New England homes. Our process typically includes:

1. Inspection & Load Assessment: Identifying which columns and beams are compromised and evaluating the home’s overall structural load.
2. Temporary Stabilization: Safely supporting the structure during repair using hydraulic jacks and shoring.
3. Column Replacement or Reinforcement: Installing new Lally columns or reinforcing existing beams to restore proper support.
4. Beam Replacement if Needed: Replacing or sistering sagging beams to ensure long-term stability.
5. Final Inspection & Adjustment: Confirming that all floors and beams are level and secure, protecting the home for decades.

This approach ensures your home is structurally safe and compliant with modern building standards, while also respecting the original construction.

The New England Factor: Why Local Homes Are Especially Vulnerable
New England’s freeze-thaw cycles, clay-rich soils, and heavy seasonal moisture put additional stress on Lally columns over time. In towns like Exeter, Kingston, Dover, Hampton, Stratham, and Portsmouth, older basements were often built without modern moisture barriers, leaving columns exposed to rust and concrete deterioration.

Over decades, these forces combine, causing sagging floors and structural stress that a simple patch cannot fix. Only trained professionals understand how to evaluate, lift, and replace these critical supports safely.

When to Call a Professional
If you notice sagging floors, leaning columns, or cracked beams, it’s time to act immediately. Lally column issues are never minor — the risk grows every season as soil settles, frost heaves occur, and moisture penetrates the basement.

DIY fixes or temporary props only delay the inevitable, potentially putting your home and family at serious risk.
