OUR HERITAGE

The Meighan-Sitzmann Heritage: 75 Years of Colorado Innovation

The foundation of All Carpentry Solutions is built upon a 75-year tradition of trade excellence. Our story is anchored by a multigenerational lineage of Colorado structural protection specialists and master carpenters. Since the mid-20th century, we have pioneered foundation integrity in expansive soils, evolving from traditional craftsmanship to forensic diagnostics. Today, we merge old-school technical grit with engineered corrective framing, ensuring every residence honors a legacy of innovation and remains structural for decades to come.

James & Constance Meighan

The architects of the standard. James pioneered the High-Pressure Hot Asphalt Spray System while Constance anchored the vision that established our lineage in structural resilience.

A generational chain of command preserving the hot-asphalt standard and the technical pedigree of Colorado's structural protection.

The Lineage of Stewardship

Uncle Tim & Michael Meighan

Stewards of the Hot Spray revolution. They maintained the technical rigor and 'old-school grit' required to protect Frontier-era and modern foundations against Colorado's expressive soils.

LEGACY & EVOLUTION

Today: The ‘Surgical’ Integration

All Carpentry Solutions now combines old-school grit with new-school Forensic Structural Diagnostics. We stand by the architectural conviction that no structure is too far gone when approached with the right vision and technical pedigree. Our 'Surgical' Integration approach honors 75 years of Colorado structural evolution, ensuring every remediation is executed with engineering-led precision and master-tier stewardship.

The Technical Heritage

The 1960 Breakthrough: From Mops to Machines

THE PRIMITIVE ERA

Before 1960, foundation waterproofing was a primitive mop-and-bucket process. This manual method often resulted in inconsistent layers and air pockets, leaving structures highly vulnerable to moisture seepage in the Front Range's complex landscape.

THE HOT SPRAY REVOLUTION

James Meighan pioneered the High-Pressure Hot Asphalt Spray System, a technological pivot that replaced hand-tools with engineering-grade machinery. This method created a seamless, impenetrable barrier that bonded directly to the substrate on a molecular level.

THE PIERRE SHALE STANDARD

This breakthrough became the industry standard for expansive Pierre Shale soils. By resolving the critical failures of moisture-driven soil shifts, Meighan’s Hot Spray system guaranteed a level of structural protection that was previously unattainable.

Forensic Genealogy & Diagnostics

We approach every assessment as a forensic study of the home’s lineage. By identifying hidden structural failures unique to the Front Range, we establish a definitive roadmap for code-tight permanence before any new member is set.

Interlocking Load Engineering

Our methodology prioritizes wood-on-wood bearing and shear-load interlocking systems. We calculate structural paths for zero-deflection performance, ensuring the integrity of your addition withstands regional soil and wind challenges.

Surgical & Standard-Setting Execution

Execution is a surgical sequence. Using industrial-grade shoring and laser-accurate framing techniques, we perform invasive remediation with total care, delivering 'Legacy Grade' results that significantly exceed standard build cycles.

Heritage Stewardship & Verification

Honoring Glenn Arnold Sitzmann’s legacy of community revitalization, we provide transparent technical verification and coordination with municipal inspectors for every project, protecting your home as a generational investment.
