Life saving fire protection · Independently owned24/7 · (888) 844-4766
Houston's commercial properties face strict fire code requirements, high-value assets at risk, and a Gulf Coast climate that demands resilient systems. At Ironsmith Fire, we deliver complete commercial fire protection—from engineered sprinkler design and in-house fabrication through installation, inspection, and 24/7 service—so you can meet compliance, protect property, and maintain operations across Harris and Fort Bend Counties.
We handle the full lifecycle of fire sprinkler and suppression systems, providing a single accountable partner from initial design through long-term maintenance. Whether you're planning new construction, retrofitting an existing facility, or managing an inspection deficiency, our Houston team brings local code expertise and dependable execution to every project and service call.
Commercial fire protection encompasses the design, installation, inspection, and maintenance of automatic fire suppression systems—primarily sprinklers—along with alarm integration, water supply verification, and compliance documentation. Houston enforces the 2018 International Fire Code with city-specific amendments, and the Houston Fire Department (HFD) reviews plans and conducts inspections to verify compliance with NFPA 13 (sprinkler installation), NFPA 20 (water supply), and NFPA 25 (inspection, testing, and maintenance). Meeting those requirements isn't just about passing inspection—it's about building systems that perform reliably when needed and stand up to the operational realities of your facility.
We maintain local crews, fabrication capacity, and service dispatch across the Greater Houston area, so projects move forward without delays and urgent service needs are handled the same day. Our team coordinates with general contractors, architects, and building officials to keep schedules on track and resolve permitting questions quickly—whether you're working in the Energy Corridor, Medical Center, or Galleria districts.
From stamped drawings to emergency repairs, we deliver every phase of fire protection in-house—reducing vendor fatigue, improving coordination, and keeping accountability at every step.
Our NICET-certified design team produces code-compliant sprinkler layouts using BIM and Revit coordination to identify clashes early and speed plan approvals. Each design aligns with NFPA 13 density requirements, NFPA 20 pump sizing calculations, and applicable Houston amendments, so your system meets both code and operational requirements for your occupancy classification.
Our UL-listed fabrication shop custom-builds sprinkler assemblies per NFPA 13 section 6.3.2, reducing lead times and giving us direct quality control over critical components. In-house fabrication means fewer delays, tighter coordination, and the flexibility to adapt to design changes or compressed schedules without waiting on third-party vendors.
Our installation teams hold OSHA 10 and OSHA 30 certifications and follow our jobsite safety protocols on every project. Safe execution reduces project risk, protects your timeline, and confirms the system is built to perform as designed—with proper hangers, seismic bracing, and hydraulic performance verified before final inspection.
We provide NFPA 25 quarterly, semi-annual, and annual inspections—including main drain tests, alarm valve trips, and backflow assembly testing—to keep systems compliant and operational. When emergencies arise—leaks, impairments, or failed tests—our service team is available around the clock to restore protection and document corrective actions for audits and re-inspections.
Every water-based system runs on NFPA 25 clocks - weekly, monthly, quarterly, annual, and 5-year cycles. Pick the systems behind your riser door and our free schedule builder maps your building’s inspection calendar in about 60 seconds.
We support a wide range of commercial, industrial, and institutional environments across Houston's diverse economy.
Hospitals, clinics, and laboratories need NFPA 99-compliant protection and rigorous regulatory compliance. We coordinate installations to minimize disruption to patient care and provide inspection services that satisfy CMS and Joint Commission requirements.

Our Texas contractor licenses and NICET credentials qualify us to design, install, and service fire protection systems across commercial, industrial, and institutional occupancies.
We hold active Texas fire sprinkler contractor licenses and maintain NICET Level III and IV certifications in water-based systems layout, providing both legal compliance and technical competency across hydraulic calculations, plan review, and field inspection activities.
We manage permitting with the City of Houston Development Services Department and coordinate with the Harris County Fire Marshal's Office when required. Our certified backflow testers handle annual RPZ and double-check assembly testing to meet TCEQ cross-connection control requirements.
Gulf Coast conditions—hurricanes like Harvey (2017), 100-year flood zones, and occasional hard freezes—require systems designed and maintained for resilience. We evaluate FEMA flood zone exposure, recommend dry-pipe or antifreeze protection for vulnerable areas, and support pre-storm impairment procedures and post-event damage assessments.
Houston adopts the 2018 IFC with amendments that modify automatic sprinkler thresholds, inspection documentation, and fire department access requirements. We stay current on those amendments through ongoing City of Houston Development Services updates and coordinate with HFD plan reviewers to verify compliance before submittal.
In-house fabrication eliminates 4–8 week vendor lead times for custom assemblies and gives us direct control over UL-listed prefab components, so we can deliver spools and rack assemblies on your critical path timeline and adapt quickly to field coordination changes during fire sprinkler installation.
Pre-storm steps include verifying fire pump diesel fuel levels, testing generator auto-start, closing OS&Y control valves only if flooding is imminent (with proper tagging), and photographing all valve positions and gauge readings. Post-storm, inspect for impact damage, verify system pressure, trip-test alarm valves, and restore any impairments immediately per NFPA 25 section 15.5.
Auditors expect current NFPA 25 ITM records, backflow test certificates, valve tamper-switch verification logs, impairment tags and restoration documentation, and stamped hydraulic calculations matching as-built conditions. We provide complete documentation with our inspection and service work, so you're prepared for any review.
Contact us with project plans or building details to receive a detailed estimate. We can also schedule a site walk to assess existing conditions, verify the adequacy of the water supply, and recommend system options.
