Firestopping Services FAQs
What does your firestopping division do?
We provide firestop installation and thermal protection services including air barrier systems, exterior and interior fire-rated assemblies, curtain wall firestopping, window protection systems, and penetration sealing for pipes, ducts, and electrical systems.
How would you explain firestopping to a non-contractor?
Firestopping is a form of passive fire protection that seals openings in fire-rated walls and floors to prevent the spread of fire, smoke, and gases, helping buildings comply with safety codes and protect occupants.
What types of projects do you work on?
We commonly work on data centers, government buildings, commercial facilities, apartment buildings, and large-scale construction projects.
What problem does firestopping solve?
Firestopping ensures building safety and code compliance by properly sealing penetrations and maintaining fire-rated assemblies. Our certifications help us stand out by meeting strict project requirements.
What does your firestopping process look like?
Our work follows the construction schedule of the project. We coordinate closely with electricians, plumbers, and mechanical contractors to install firestopping as penetrations are created. Scheduling is typically directed by the general contractor.
How quickly can you complete firestopping work?
Project timelines vary significantly—from short-term work lasting a few hours to long-term projects spanning multiple years, depending on scope and building size.
What equipment do you use?
We primarily use firestop sealants, caulking systems, and manufacturer-approved firestop materials designed for specific applications.
What makes your approach different?
We offer highly experienced crews, many with 20–30 years in the industry, and long-term installers who have been with the company for 15+ years. This provides consistency, quality, and reliability on every project.
What types of penetrations do you firestop?
We seal penetrations including pipes, ductwork, electrical systems, cable trays, bus ducts, and telecommunications cabling.
What happens if firestopping is missing or incorrect?
Improper firestopping can allow fire and smoke to spread rapidly through a building. In severe cases, unsealed penetrations can act like a channel for fire movement between floors or rooms. All work is inspected to ensure compliance with safety standards.
How do inspectors verify firestopping?
Inspectors perform visual inspections and may conduct destructive testing to confirm proper installation depth, materials, and sealing methods. We regularly work with third-party inspectors to ensure compliance.
What codes apply to firestopping?
Firestopping work is performed in accordance with applicable life safety codes, local building regulations, and project specifications, including Division 07 80 00 standards where applicable.
What do customers ask most often?
Customers frequently ask whether we are certified and whether pricing is fair, transparent, and competitive.
What do customers misunderstand about firestopping?
Many clients understand the basics, but the technical requirements can be complex. Certifications such as FM4991 approval and UL-qualified systems are critical and often misunderstood in specifications.
When do customers realize they need firestopping?
Most customers identify the need during project planning, especially in construction environments. Others discover compliance issues during inspections and require corrective firestopping work.
Thermal & Moisture Protection FAQs
What does thermal protection include?
Thermal protection includes interior and exterior wall insulation, curtain wall systems, steel beam protection, air barriers, and underslab insulation for commercial structures.
When is thermal protection required?
Thermal protection is required in most building envelope systems and varies depending on building design, curtain wall systems, and energy efficiency requirements.
How would you explain thermal and moisture protection?
It is insulation and protection installed within and around a building envelope to regulate temperature, prevent moisture intrusion, and improve energy efficiency.
Where is it typically installed?
Thermal and moisture protection is installed in walls, ceilings, roofs, around piping systems, under slabs, and within building envelopes.
What problems does it solve?
It prevents air leakage, moisture intrusion, energy loss, and structural damage while improving building efficiency and comfort.
What causes moisture-related issues?
Moisture problems often occur in walls, glass systems, or improperly sealed building envelopes, leading to leaks, mold, rust, and structural deterioration.
Do thermal systems overlap with firestopping?
Yes. In many commercial projects, thermal protection systems and firestopping systems are installed in coordination during construction.
Concrete Services FAQs
What concrete services do you offer?
We provide concrete sawing, slab and wall cutting, core drilling, demolition, grinding, pourback, and ground penetrating radar (GPR) scanning.
Do you offer emergency services?
Yes, we provide 24/7 emergency concrete cutting, drilling, and scanning services.
What is GPR scanning?
Ground Penetrating Radar (GPR) is a non-destructive method used to locate rebar, conduits, post-tension cables, and other embedded objects before cutting or drilling concrete.
What are your most common concrete services?
We frequently support electricians, plumbers, HVAC contractors, and general contractors on commercial and industrial projects.
What happens if concrete work is done incorrectly?
Improper concrete work can create safety hazards, damage utilities, and violate local building codes. Proper containment and wet-cutting methods are used to maintain safety.
Fireproofing FAQs
What is fireproofing in construction?
Fireproofing is the application of protective materials to structural steel and other load-bearing components to help them resist high temperatures during a fire. This helps maintain the structural integrity of a building long enough for safe evacuation.
Why is fireproofing important?
Fireproofing is critical because steel loses strength at high temperatures. Proper fireproofing helps slow that process, reducing the risk of structural failure and helping protect occupants during a fire event.
What materials are used for fireproofing?
Common fireproofing systems include:
- Cementitious fireproofing
- Intumescent fireproofing
- Rigid board fireproofing
- Structural steel beams
- Columns
- Joists
- Floor and roof deck assemblies
- Multi-story commercial buildings
- Mixed-use developments
- Industrial facilities
- High-occupancy structures
- Maryland
- Washington D.C.
- Virginia
- Pennsylvania
- Project location
- Scope of work
- Site conditions
- Working hours
- Available drawings or plans
- General contractors
- Subcontractors
- Property managers
- Government agencies
- Commercial developers
Each system is selected based on project requirements, exposure, and architectural finish needs.
Where is fireproofing typically applied?
Fireproofing is typically applied to:
It is commonly required in multi-story commercial and industrial buildings.
Is fireproofing required by building code?
Yes. Fireproofing is required in many building types depending on height, occupancy, and structural design. Requirements are determined by applicable building codes and project specifications.
How long does fireproofing last?
Fireproofing is designed to last the life of a building, but it should be inspected if it is exposed to damage from renovations, repairs, or building modifications.
Can fireproofing be repaired or replaced?
Yes. Damaged or missing fireproofing can be repaired or replaced. It is important that repairs match the original approved system and manufacturer specifications.
How is fireproofing installed?
Fireproofing is typically installed using spray-applied systems or board materials. Cementitious systems require larger spray equipment, while intumescent systems are applied in thinner coatings for exposed architectural areas.
What happens if fireproofing is damaged or missing?
If fireproofing is missing or compromised, structural steel may be exposed to high heat during a fire, which can reduce its load-bearing capacity and increase the risk of structural failure.
What types of buildings require fireproofing?
Fireproofing is commonly required in:
Typically, buildings three stories or higher require fireproofing depending on design and code requirements.
Do you provide fireproofing inspections?
G&M Services can coordinate inspections, but third-party inspectors are typically used to avoid conflicts of interest. We can assist with recommendations and remediation if needed.
When is fireproofing applied during construction?
Fireproofing is typically applied after structural steel is installed and the building is enclosed, but before interior finishes and mechanical/electrical systems are fully completed.
Does spray-applied fireproofing affect appearance?
Yes. Cementitious fireproofing typically results in a textured finish, while intumescent fireproofing provides a smoother, more visually appealing coating for exposed structural steel.
Can fireproofing be installed in finished spaces?
Yes. In finished or sensitive spaces, rigid board fireproofing can be used to provide fire protection without disrupting completed interior environments.
