Elevate Fire Safety for Your Business

At Alliance Environmental, we understand the critical role that fire doors play in ensuring the safety of your building and its occupants. Our comprehensive Fire Door Services are designed to help you maintain compliant and reliable fire doors that provide optimal protection. Whether you need fire door inspection and repair, recertification and relabeling, or even complete fire door replacements, we’ve got you covered.

Comprehensive Fire Door Services

Fire Door Inspection & Repair: Our team of skilled professionals is equipped to perform thorough fire door inspections to identify any potential issues or deficiencies. Through meticulous examination, we assess various components such as door frames, hardware, seals, and more. If any repairs are needed, we have the expertise to promptly address the problems, ensuring that your fire doors are fully functional and up to code.

Fire Door Recertification & Relabeling: Fire door recertification and relabeling are essential to maintain the validity of your fire doors’ performance ratings. Over time, labels and certifications can become worn or illegible, potentially compromising the door’s compliance. Our experts can assess the door’s fire rating, smoke seals, and other critical components before affixing new labels that accurately reflect its capabilities. This process ensures that your fire doors continue to meet safety regulations.

Fire Door Replacements: If your fire doors have undergone excessive wear and tear, sustained damage, or are no longer compliant, it might be time for replacements. Our fire door replacement services encompass the entire process – from assessing your needs and recommending suitable options to installing new fire doors with precision. We collaborate with leading manufacturers to provide you with high-quality fire doors that adhere to the latest industry standards.

Our Process


We begin by gathering all the essential documentation, including building plans, fire door specifications, and previous inspection records. Our team ensures that all necessary inspection tools are on hand, such as tape measures, flashlights, and inspection forms.

Regulatory Knowledge

Our certified inspectors are well-versed in local, state, and national fire codes and regulations, ensuring that every inspection is conducted with full compliance in mind. Our technicians are certified through multiple channels, including IFDIA and FDIA.

Visual Inspection

We initiate the inspection with a thorough visual examination of the fire door and its components. This involves scrutinizing the door for any damage, wear, or missing parts. Our experts carefully assess the door frame, hinges, door closer, latch, and all auxiliary hardware. We pay close attention to any gaps or openings that may compromise the door’s effectiveness in containing fire and smoke.

Operational Testing

Our team conducts rigorous tests to ensure the fire door operates smoothly and as intended. This includes verifying that the door opens, closes, and latches securely. We evaluate the door closer, guaranteeing it functions flawlessly. Self-closing doors have their release mechanisms tested for optimal performance.

Seal and Gap Inspection

We meticulously inspect the seals and gaskets surrounding the door for any signs of damage, wear, or incorrect installation. Ensuring that smoke and intumescent seals are in pristine condition is a top priority.

Label and Certification Verification

Our experts carefully examine the fire door’s label or certification tag to confirm its legibility and accuracy. We cross-check it against the door’s intended use and fire rating. All pertinent information on the label, including the manufacturer’s details, and fire rating, is verified.

Door Hardware Inspection

Our team assesses all door hardware components, such as locks, panic bars, and handles, for proper installation and functionality. We ensure that any glazing or vision panels are fire-rated and free from damage.

Clearance and Undercut Measurement

We measure the clearance between the door and frame to ensure it falls within code requirements. The undercut, or gap beneath the door, is meticulously measured to confirm it meets compliance standards.


We maintain detailed inspection reports that encompass all findings, including deficiencies. If necessary, we include photographic documentation. Any recommended repairs or replacements are documented for your reference. We also maintain meticulous records of all fire door inspections, repairs, and maintenance activities, providing you with the documentation needed for compliance and future reference.

Recommendations and Follow-up

Based on our inspection results, we provide you with clear recommendations for any required repairs or maintenance. We work with you to schedule and carry out these necessary actions promptly, ensuring your fire doors remain compliant and safe. After any repairs or maintenance, we conduct a follow-up inspection to confirm that all issues have been successfully addressed, and your fire doors now meet compliance standards.

Compliance Requirements

Fire Door Ratings: Fire doors must have a specific fire-resistance rating that corresponds to the duration of fire protection they are designed to provide (e.g., 20 minutes, 45 minutes, 60 minutes, 90 minutes, or 3 hours). Compliance requires selecting fire doors with the appropriate rating for their location and intended use.

Proper Installation: Fire doors must be installed according to the manufacturer’s specifications and local building codes. Compliance includes ensuring that the door, frame, hardware, and any glazing are correctly installed.

Clearance and Undercut: Compliance requires maintaining specific clearance and undercut measurements to prevent the passage of smoke and flames around the edges of the door. These measurements are typically specified in local fire codes.

Self-Closing and Self-Latching: Fire doors must be equipped with self-closing devices and self-latching hardware to ensure that they automatically close and latch when released. Compliance involves verifying the functionality of these mechanisms during inspections.

Labeling and Certification: Every fire door must have a label or certification tag that provides essential information, including the manufacturer’s details, and fire rating. Compliance requires that labels are accurate, legible, and in the correct location.

Seals and Gaskets: Fire doors are equipped with seals and gaskets to prevent the spread of smoke and fire. Compliance involves ensuring that these seals are in good condition and meet the necessary performance standards.


Operational Testing: Compliance requires that fire doors are regularly tested to ensure they operate correctly. This includes verifying that they close and latch securely when released and that self-closing mechanisms work as intended.

Maintenance and Repairs: Fire doors must be kept in good working condition. Compliance involves promptly addressing any deficiencies or damage identified during inspections and conducting necessary repairs or maintenance.

Accessibility: Fire doors serving as exit routes must comply with accessibility standards to ensure that they are usable by all occupants, including those with disabilities. This includes appropriate door hardware, clear openings, and signage.

Emergency Exit Hardware: Compliance may involve using specific types of emergency exit hardware on fire doors to allow for quick egress during an emergency while preventing unauthorized entry.

Glazing and Vision Panels: If fire doors have glazing or vision panels, compliance requirements dictate that the glazing materials be fire-rated and that any framing or glazing components are appropriately installed.

Regular Inspections: Routine fire door inspections, conducted annually, are necessary for compliance. These inspections help identify and address issues that may arise over time.

Records Keeping: Compliance often requires maintaining detailed records of fire door inspections, repairs, and maintenance activities. These records serve as evidence of compliance with regulatory requirements.
