What are lally columns?
The lally column was first manufactured in the late 1800s by a building company run by an Irish entrepreneur named John Lally. A long, round steel pipe positioned vertically to support beams or timbers across wide spans is known in architecture as a Lally column. The columns are usually placed in the middle of the span to help the weight of the building and lessen its tendency to sag or bend.
Ordinarily, though not always, the lally column is filled with concrete to increase stiffness and strength and eliminate associated foundation problems. In most residences and residential buildings, these columns are almost always located in the basement.
Lally columns may be left in place as extra columns, but they are typically used as temporary supports while permanent structural features are being built. The columns are typically equipped with head and foot plates to distribute loads and stop the cylinder from gouging into the supported wood.
How do Lally Columns work?
Lally columns serve as vertical pillars within edifices, responsible for the crucial task of transmitting the immense weight of the superstructure to the underlying foundation. The weight-bearing potential of these columns hinges upon an array of factors, encompassing their diameter, wall thickness, material composition, and overall length. When it comes to longer columns, the propensity for buckling or deformation under the imposed load necessitates a proportional increase in diameter to sustain comparable weight.
In the realm of construction, established norms govern the load-carrying capacity of lally columns, drawing upon the dimensions of their diameter and length. It is imperative to engage the expertise of a structural engineer or another qualified professional prior to the selection and installation of lally columns. Such caution arises from the fact that the weight capacity is contingent upon the installation technique employed, as well as the existing conditions of the foundation and surrounding structure.
Temporary vs. Permanent Lally Columns
There are two types of Lally columns: temporary and permanent. Workers frequently use temporary columns to brace the floor joists above when removing a wall. On the other hand, endless columns are used in the basement or crawlspace to strengthen the structure underneath a house.
Adjustable Lally Column Range
Adjustable lally columns, also known as screw jacks or basement support columns, are vertical support columns that can be adjusted to a specific height to provide support for the structure above. These columns consist of two or more telescoping sections that can be extended or retracted to achieve the desired height.
Non-Adjustable Lally Columns
One variety of these columns cannot be adjusted. Thus the steel column needs to be chopped to meet the required space. Although lesser diameters are occasionally available, these columns are typically made of 11-gauge steel and have a 4-inch diameter. These columns can be covered with wood and drywall or exposed when utilized in a finished basement. Painting exposed columns is an option.
Examples of the Use of Lally Columns
To maintain the house’s structural integrity when removing an interior, load-bearing wall, a builder or home remodeling contractor will replace the demolished wall with a series of lally columns. Later, when the wall is rebuilt, or another bracing is placed, these posts will be taken down. An example is a beam.
Short jack posts are frequently positioned in difficult to reach spots like crawlspaces and basements to fix sagging floors.

Testimonials
Annette Casatelli
I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.
They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.
Noemi Herles
Our experience with Zavza Seal was wonderful and smooth. The crew is well organized. They listen to your plans. They showed out in time. They left everything clean. They did an amazing job! I highly recommend this company.
Ellen Szuchmacher
Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.
Michael Rutigliano
Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
