Structure Fireproofing: Price and Budgets
The average cost of fireproofing a structure will depend on both its dimensions and the materials chosen or the degree of fire protection required. On average, it can cost around 15 €/m². For example, fireproofing a small-sized warehouse with fire-resistant mortar could cost around 8.000 €.
The amounts are indicative and come from the imported original guide. The final budget depends on the scope, materials, and previous condition of the space.

Steps for fireproofing structures: Price and quotes with Reformia
The average cost of fire-resistant coating a structure will depend on both its dimensions and the materials chosen or the degree of fire protection required. On average, it can cost around 15 €/m². Thus, fire-resistant coating an industrial building of small dimensions with fire-resistant mortar could cost around 8,000 €.

1. Assess the structure's dimensions
The first step is to accurately measure the surface area of the structure to be fireproofed, as this directly determines the final budget. For industrial buildings, this calculation is critical: fireproofing a warehouse with fireproof mortar can range around 1,000 € depending on size. Gather blueprints or exact measurements before contacting installers.

2. Identify the type of existing material
Identify the materials that make up your structure: wooden beams, iron, steel, or a combination. Each material requires specific products—for example, wooden beams need fireproof varnish (from 10 €), while metal structures require paint or fireproof rock wool. This information is essential for obtaining accurate quotes.

3. Determine the required protection level
Determine the level of protection needed based on the structure's use and local regulations. Basic solutions (4,000 € – 8,500 €) are sufficient for secondary structures, while premium installations (18,000 € – 45,000 €) offer comprehensive protection in critical commercial or industrial buildings. Consult with experts about your specific needs.

4. Request quotes from multiple installers
Contact at least 3-4 installers specialized in structure fireproofing to obtain comparable quotes. The average service price is 24,500 €, but varies significantly based on materials and complexity. Ensure each quote includes details about products, labor, and warranty coverage.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Size and surface area of the structure
The total cost is calculated primarily based on the square meters of surface to be treated. Larger structures require more material and labor, which significantly impacts the final budget.
Type of fire-resistant material used
There are different options such as fire-resistant mortars, intumescent paints, gypsum plasterboard, or spray-applied systems. Each material has a different cost and offers varying levels of protection.
Required protection level (REI classification)
Depending on applicable regulations and building use, different levels of fire resistance are required (REI 30, REI 60, REI 120, etc.). Higher protection requires more material and more complex techniques.
Accessibility and structural complexity
Structures with complicated geometries, difficult-to-access elements, or those requiring special scaffolding significantly increase costs due to greater application difficulty.

Fire-resistant coating methods
The average cost of fire-resistant coating a structure will depend on both its dimensions and the materials chosen or the degree of fire protection required. On average, it can cost around 15 €/m². Thus, fire-resistant coating an industrial building of small dimensions with fire-resistant mortar could cost around 8,000 €.
Fire-resistant coating is a passive fire protection solution. Its objective is to provide greater resistance to surfaces against flames. In this way, its spread is slowed down, the time margin to act against it is extended, and damage is minimized, sometimes even preventing structures from collapsing due to fire.

Thus, fire-resistant coating an industrial building of small dimensions with fire-resistant mortar could cost around 8,000 €.
To apply fire-resistant coating to a metal, concrete, or even wooden structure, different techniques can be used. When choosing one system or another, you should first consider the level of flame resistance needed and, second, the type of structure or element that needs fire-resistant coating: beams and columns, ceilings, or walls.
Fire-resistant mortars
- Labor: it is customary to charge by projects rather than by hours of work. In the latter case, the measure can be around 18 € - 20 €/hour. The price can increase depending on the difficulties involved in the work, for example, when performed at great heights.
- Dimensions of the structure: the budget depends directly on the surface area that needs to be fire-resistant coated. The larger it is, the more material and working hours will be needed to complete it.
- Fire-resistant coating method: the application of intumescent paints and fire-resistant mortars is usually more economical than the installation of rigid panels. The price difference between them can reach 30 %. In any case, the quality and thickness of the material can also influence the cost of the work.
- Other services: if in addition to the structure it is necessary to fire-resistant coat iron or wooden beams, columns, or other elements, the cost of the work will increase. It will also increase if, in addition to these passive fire protection measures, other active protection measures are applied such as installation of fire detectors and alarms or fire extinguishers. A complete detection and alarm system in an industrial building can cost around 2,000 €.
They can have a cement or plaster base. In the first case, it is combined with rock wool and, in the second, with perlite or vermiculite to improve the fire resistance of the material. There are other differences: cement-based mortar is lighter and easier to apply, while plaster-based offers greater surface hardness. Both can be applied manually or by spraying and combined with protective meshes.
It is a common system in all types of metal structures and its main drawback is an unaesthetic finish. In return, it is more economical than other systems: fire-resistant coating of a metal structure with this system will start from 13 €/m².
Mineral fiber mortars
- Fire-resistant coating the metal structure of a building (around 500 m²) with fire-resistant mortar will have an approximate cost of around 6,500 €.
- Fire-resistant coating 8 steel beams of a small industrial establishment with intumescent paint will have an approximate cost of 650 €.
- Installing fire-resistant panels on a party wall of around 100 m² of an industrial building can cost around 3,000 €.
- Applying mineral fiber mortar to fire-resistant coat 4 concrete columns will cost around 400 €.

Frequently Asked Questions

What is the approximate cost of fireproofing a structure?
The average cost of fireproofing structures is around 15 €/m², though it can vary significantly depending on size and materials. For a small warehouse of about 500 m² with fireproof mortar, the total budget ranges between 7,500 and 10,000 €. Larger structures or those requiring higher-grade protection can easily exceed 20,000 €.
What is included in a structure fireproofing quote?
A typical quote includes surface preparation, application of the fireproofing product (mortar, paint, or coating), specialized labor, and certification of the work performed. It usually does not include prior structural repairs, though some installers offer these as an additional paid service.
How long does it take to fully fireproof a structure?
The time depends on size and complexity: a small warehouse can be completed in 3-5 days, while larger structures require 2-4 weeks. Additionally, allow 1-2 weeks for the material to fully cure before the structure can be used without restrictions.
Do I need permits or certificates to fireproof a structure?
Yes, in Spain it is mandatory to obtain a certificate of compliance for work performed in accordance with current regulations (CTE, UNE standards). The professional installer must provide technical documentation and certificates proving that materials comply with applicable fire protection regulations.
How do I choose the best professional to fireproof my structure?
Look for certified installers with proven experience in fireproofing structures similar to yours. Compare at least three detailed quotes that include the type of material, coverage, and warranty offered.
