The Foundation of Structural Safety in Massachusetts Homes

Lally Columns in Massachusetts: Most Frequently Asked Questions (FAQ)

Lally columns are essential components in both residential and commercial construction, providing critical support to beams and floor systems. These steel columns, filled with concrete, are designed to transfer the weight of upper floors down to the foundation, preventing sagging and structural shifts. Named after John Lally, a Massachusetts innovator, these columns have been a staple in building safety since the early 1900s. At Goodwood General Construction, we are committed to ensuring your home remains safe and compliant with state regulations through expert Lally column installation and replacement.

Here are answers to some of the most frequently asked questions from Massachusetts homeowners.

Common Questions About Lally Columns

Find answers to your most pressing questions about Lally columns and their role in your home’s structural integrity.

What Are Lally Columns Used For?

Lally columns are used to support vertical loads in buildings, typically found in basements and crawl spaces. They help distribute the weight of upper floors to the foundation, ensuring structural stability.

Are Lally Columns Required by Massachusetts Building Code?

Yes, when structural support is needed, the Massachusetts State Building Code (780 CMR) requires columns that meet specific load-bearing standards. Lally columns fulfill this by providing:

  • At least 3″ diameter of steel

  • Concrete fill for compressive strength

  • Proper footings and anchoring

Temporary jack posts or non-concrete-filled hollow steel posts do not meet code for permanent use. To comply with building regulations, all load-bearing columns must be code-approved and permanently secured.

How Do I Know If My Lally Columns Need Replacement?

You should consider replacement if your current Lally columns show:

  • Excessive rust or corrosion

  • Visible cracks or bulges

  • Movement or instability

  • Are temporary jack posts

Also, during a home remodel or basement finishing project, it’s often necessary to upgrade old supports to meet current code and improve layout.

Do I Need a Permit to Replace or Install a Lally Column?

Yes. Any work involving the addition or replacement of a structural support column requires a building permit in Massachusetts. This includes:

  • Replacing rusted or damaged columns

  • Installing new supports as part of a remodel or addition

  • Upgrading temporary posts to permanent, code-compliant Lally columns

Permits ensure the work meets code and is properly documented for future home sales or inspections.

How Much Does It Cost to Replace or Install a Lally Column?

Costs vary based on accessibility, condition, and whether new footings are needed. On average:

  • Simple replacement: $1,500–$2,500 per column

  • New installation with footing: $2,000–$3,500+ per column

Factors that impact cost include the need for:

  • Custom cutting and fitting

  • Concrete footings

  • Decorative wrapping or finishes

We provide transparent pricing and expert service to ensure a lasting, compliant installation.

Can I Replace a Lally Column Myself?

Lally column replacement involves supporting the structure temporarily, removing the old column, preparing the footing, and installing a new, properly sized and anchored column. This is not a DIY job — it requires experience with load-bearing systems and code compliance.

Let professionals like Goodwood General Construction handle it safely and correctly.

Are Adjustable Posts Allowed?

No. Adjustable jack posts (also called screw jacks or tele-posts) are only allowed as temporary supports. Massachusetts code requires permanent structural columns to be fixed, non-adjustable, and made from approved materials such as concrete-filled steel.

Using adjustable posts long-term is a safety hazard and a code violation.

What Types of Lally Columns Are Available?

We typically work with:

  • Standard Lally Columns – pre-cut steel tubes filled with concrete

  • Custom-Cut Columns – tailored to specific heights

  • Heavy-Duty Options – for higher loads or commercial spaces

All our installations are performed using code-compliant columns rated for your home’s structural demands.

Can I Remove a Lally Column to Open Up My Basement?

Only if an engineered beam or support system is installed to redistribute the load. Never remove a structural column without a professional design and proper permitting.

We can replace or relocate Lally columns as part of a structural layout change, ensuring safety and compliance throughout the process.
