Mono Post Installation
Mono Post Installation for Pier & Beam Homes
Mono posts provide concentrated support where a pier and beam home needs it most. Over time, original supports can sink, tilt, or fail to carry the load they were intended to handle. Installing new steel mono posts in the crawl space can help correct sagging floors, reduce bounce, and improve the overall stability of the structure.
Mono post work is often recommended after a crawl space inspection has identified areas where the home has lost support or where new load points are needed.
What Is a Mono Post?
A mono post is a vertical steel support installed beneath beams or girders in the crawl space. It is typically set on a properly sized concrete footing and adjusted to carry a specific portion of the home’s load. Unlike improvised supports or stacked blocks, a well-installed mono post system offers consistent, adjustable, and reliable support over time.
When We Recommend Mono Post Installation
Mono posts are commonly used when certain areas of the home show more sagging or bounce than others. This can happen in living rooms with long spans, hallways, or rooms where additional weight has been added over the years. Signs your home may benefit from mono posts include:
- Floors that feel springy or bouncy underfoot
- Localized sagging in specific rooms
- Visible deflection in beams or subfloor
- Cracks in walls or ceilings directly above crawl space spans
In some situations, mono posts work alongside other repairs such as wood beam (girder) replacement or joist replacement to fully restore support.
The Brown Approach to Mono Post Installation
At Brown Foundation Repair, mono posts are never installed as a quick fix. Our project planners determine the appropriate locations, footing sizes, and load paths before any work begins. Posts are set on solid, properly prepared supports—not directly on bare soil. We then adjust each post carefully to provide the right amount of lift and support without stressing the structure.
Mono post installation may be combined with crawl space adjustments to improve overall alignment and floor levelness throughout the home.
