Envelope systems we install

01

EIFS

Insulated finish systems engineered for performance

Drainage EIFS assemblies installed to manufacturer specifications by trained crews — continuous insulation, drainage plane, base coat, mesh, and finish. Modern EIFS is a code-recognized, high-performance wall system when it’s installed right, and installing it right is exactly what we do.

  • Drainage EIFS assemblies
  • Manufacturer-specified installation
  • Aesthetic reveals, banding & shapes
  • High-durability finish options
02

Fluid-Applied Air & Moisture Barriers

The invisible layer that protects everything

The barrier is where envelope performance is won or lost — and it’s invisible the day after the cladding goes on. We install fluid-applied air and water-resistive barriers with the transition detailing at openings, penetrations, and dissimilar materials that keeps water out for the life of the building.

  • Fluid-applied WRB / air barrier systems
  • Transition membranes & opening details
  • Assembly compatibility review
  • Mockups & adhesion verification
03

Joint Sealants

Movement control and watertightness

Facade expansion and control joints, window perimeters, and dissimilar-material joints — properly sized, backed, and tooled. Sealant work is small line items and large consequences; we treat it as a craft scope, not a punch-list afterthought.

  • Facade expansion & control joints
  • Window perimeter & transition joints
  • Joint design per ASTM C1193 guidance
  • Adhesion (pull) testing
04

Rainscreen Panels & Fiber-Cement Siding

Modern cladding over engineered substrates

Fiber-reinforced cementitious panel systems and fiber-cement siding over furred, ventilated cavities — integrated with the air barrier and flashing detailing behind them. One contractor for the barrier and the cladding means the interface actually gets built as designed.

  • Fiber-reinforced cementitious panels
  • Fiber-cement lap & panel siding
  • Furring, subframing & ventilation cavities
  • Integrated barrier & flashing detailing

Technical capabilities, field-proven

Thermal and moisture protection is a systems trade — every layer has to work with the one behind it. These are the competencies that make the assembly perform.

Manufacturer-Trained Crews

Installation crews trained to the specified manufacturer’s requirements for each system, protecting both performance and system warranties.

Envelope Transition Detailing

Leaks happen at transitions — window heads, material changes, penetrations, terminations. Detailing those interfaces correctly is our core Division 7 competency.

Self-Perform Crews

Our own field crews install the barrier, the cladding, and the sealants — single-source responsibility for the envelope scopes that usually get split and finger-pointed.

QC & Field Testing

Mockups, adhesion pull tests, and in-progress inspections documented at each phase — verification, not assumption.

North & South Carolina

Field operations across the Carolinas with centralized logistics from the Triangle, and mobilization capacity for the projects that take us further.

Code Compliance

Assemblies installed per IBC Chapter 14, IECC continuous-insulation requirements, and the tested configurations specified by the design team.

Sectors we serve

Our capability and capacity extend to a variety of project sizes and types across the Carolinas.

Built to code and standard

Envelope failures are expensive, slow to appear, and always someone’s fault. We install to the governing codes, tested assemblies, and manufacturer requirements — documented at every step.

IBC Chapter 14

Exterior wall code requirements — weather protection, water-resistive barriers, and cladding attachment

IECC

Energy code continuous-insulation and air-leakage requirements for the building thermal envelope

ASTM E2178 / E2357

Air permeance of materials and air leakage of assemblies — the basis for air barrier performance

ASTM C1193

Standard guide for use of joint sealants — joint design, backing, and installation practice

NFPA 285

Fire propagation of exterior wall assemblies — we install assemblies consistent with the tested configurations specified by the design team

EIMA Guidelines

EIFS Industry Members Association installation and detailing guidance

Manufacturer Specifications

Each system installed per the manufacturer’s published details and warranty requirements

OSHA 1926

Scaffold, fall protection, and jobsite safety compliance on every envelope operation

How we execute every project

01

Preconstruction & Assembly Review

We review the full wall assembly — not just our scope — to flag compatibility issues, sequencing conflicts, and detailing gaps before they become field problems.

02

Submittals & Compatibility

System submittals with compatibility verification across barrier, insulation, cladding, and sealant products from potentially different manufacturers.

03

Mockups & Adhesion Testing

Field mockups of typical and critical details, with adhesion testing that verifies the specified products actually bond to the actual substrates on site.

04

Barrier & Substrate Installation

Air/moisture barrier and transition detailing installed and inspected before it disappears behind cladding — with photo documentation of concealed conditions.

05

Cladding & Finish Installation

EIFS, panels, siding, and sealants installed by trained crews to manufacturer requirements, coordinated with adjacent trades at every interface.

06

QC, Punch & Warranty

Final inspections, punch execution, and delivery of warranty documentation — manufacturer system warranties plus our installation warranty.
