Our specialties
Based in Tempe, AZ, we perform our specialty scopes on projects across Arizona for Home builders, General Contractors, Developers, M.E.P, and specialty trades.
Firestopping
Arizona Specialty Contracting delivers code-compliant firestopping solutions designed to protect lives, property, and construction schedules across Arizona. Our certified firestop professionals seal penetrations and construction joints in walls, floors, and ceilings to prevent the spread of fire, smoke, and toxic gases throughout the building envelope. We install tested and listed firestop assemblies for electrical, plumbing, HVAC, and low-voltage/data systems using proven products from trusted manufacturers to ensure long-term performance and certification.
As a UL-Qualified and Factory Mutual–approved contractor, we provide detailed documentation, as-built records, and inspection-ready labeling to help general contractors, developers, and subcontractors pass inspections on the first attempt—reducing rework and costly delays. From high-rise buildings and healthcare facilities to data centers and multifamily developments, Arizona Specialty Contracting delivers engineered firestopping solutions that meet Arizona building codes, NFPA standards, and aggressive project timelines.
Mechanical insulation
Our mechanical insulation services are engineered to improve system efficiency, enhance occupant comfort, and support fire and life-safety objectives in Arizona’s demanding climate. Arizona Specialty Contracting insulates piping, ductwork, boilers, chillers, and mechanical equipment using premium materials including fiberglass, mineral wool, closed-cell foam, and specialty facings selected for each application.
Proper mechanical insulation minimizes heat loss, controls condensation, reduces noise, and extends equipment lifespan—delivering measurable energy savings and lower operating costs over time. Our team coordinates closely with HVAC, plumbing, and industrial trades to ensure proper sequencing, accurate fabrication, and clean installation on fast-track construction schedules. Serving hospitals, schools, industrial facilities, and high-rise residential projects across Arizona, we deliver specification compliance, quality assurance, and reliable performance owners and contractors can trust.
Seismic expansion joints
In Arizona’s dynamic building environments, properly installed expansion joints are essential for long-term structural performance. Arizona Specialty Contracting installs and maintains expansion joint systems designed to accommodate building movement caused by thermal expansion, seismic activity, and structural settlement—while preserving fire, smoke, and water barriers.
We specify and install industry-leading expansion joint systems for floors, walls, roofs, and curtain walls in hospitals, airports, parking structures, campuses, and high-rise buildings. Our integrated approach coordinates expansion joints with firestopping, waterproofing, and architectural finishes to maintain code compliance without sacrificing appearance. With a deep understanding of IBC and NFPA requirements, our team works closely with structural and architectural partners to deliver inspection-ready solutions that enhance building resilience and reduce lifecycle maintenance.
Intumescent coatings
Intumescent coatings provide high-performance fire protection for exposed structural steel while maintaining architectural design intent. Arizona Specialty Contracting applies water- and solvent-based intumescent systems that expand when exposed to high temperatures, forming a protective char that preserves steel integrity and delivers UL-classified fire ratings.
Our certified applicators emphasize precise surface preparation, accurate mil-thickness application, and strict quality control to ensure consistent, code-compliant results. Intumescent coatings are ideal for exposed beams, columns, and open-ceiling designs where traditional fireproofing is impractical. We serve commercial, residential, educational, and industrial projects throughout Arizona, offering guidance on maintenance and recoat strategies to protect long-term investments while meeting insurance and building code requirements.
Fire wraps
Fire wrap systems protect critical building components where rigid fireproofing solutions are not feasible. Arizona Specialty Contracting installs UL-classified flexible fire wraps for grease ducts, kitchen exhaust systems, critical electrical circuits, fuel lines, and other high-risk assemblies. These lightweight systems are engineered to limit heat transfer, delay flame spread, and maintain compartmentation during a fire event.
Our experienced installers work efficiently in tight and congested spaces, coordinating with mechanical and electrical trades to ensure seamless integration with firestopping and insulation systems. Whether for new construction, renovations, or life-safety upgrades, our fire wrap installations meet UL, ASTM, and local Arizona code requirements while delivering dependable performance and inspection-ready documentation.
Joint sealants & architectural caulking
High-quality joint sealants and architectural caulking are critical for protecting building envelopes from water intrusion, air leakage, and premature deterioration. Arizona Specialty Contracting installs sealants at expansion joints, curtain walls, window perimeters, precast panels, masonry joints, and wet-area transitions using premium silicone, polyurethane, and hybrid products selected for movement capability, adhesion, and UV resistance.
Our crews deliver clean, uniform tooling and professional finishes that meet both aesthetic and performance standards suited to Arizona’s climate. Integrated with waterproofing and firestopping systems, our caulking services help prevent moisture intrusion, energy loss, and long-term structural damage—reducing maintenance costs for owners while ensuring code compliance.
Heat trace for grease waste and fuel oil lines
Arizona Specialty Contracting designs and installs precision heat trace systems that keep grease waste and fuel oil lines flowing safely and efficiently. Using advanced nVent RAYCHEM self-regulating heat trace technology, we maintain consistent temperatures that prevent fats, oils, and grease (FOG) from solidifying and ensure reliable fuel flow in critical systems.
Our certified technicians deliver energy-efficient, code-compliant heat trace installations for restaurants, hospitals, industrial facilities, and high-performance buildings throughout Arizona. By reducing blockages, downtime, and maintenance demands, our heat trace solutions extend system life and support continuous operations. From grease waste systems maintained at 110°F to fuel oil lines operating between 40°F and 110°F, we provide complete design, installation, and long-term support.
Turnkey sales, installation & repair — tubs, showers & accessories
Arizona Specialty Contracting provides turnkey procurement, installation, and repair services for tubs, showers, and bathroom accessories across multifamily, hospitality, student housing, and residential projects in Arizona. Our single-source approach simplifies scheduling by managing product selection, delivery logistics, installation, and on-site adjustments for fiberglass, acrylic, and cultured-marble units.
We also install ADA-compliant accessories—including grab bars, shower seating, and shelving—to meet accessibility and code requirements. Whether supporting new construction or large-scale replacement programs, our teams coordinate closely with plumbing and finishing trades to minimize punch-list items and accelerate project turnover. With responsive repair services and warranty support, we help keep projects on schedule and bathrooms fully functional.
