Services
Thermocrete
Thermocrete provides a spray-applied ceramic coating that restores damaged flue liners. This heat-resistant solution seals cracks while maintaining proper flue dimensions. Professionals use specialized equipment to apply the coating, creating a seamless barrier against creosote buildup and corrosive emissions. The system meets UL 1777 safety standards and carries a limited lifetime warranty.
Smoktite
Smoktite addresses damaged smoke chambers with a high-temperature ceramic formula. The spray application creates a smooth, insulating surface that improves draft efficiency while preventing heat transfer. Installation completes in one visit without dismantling existing structures. Certified technicians apply the coating to meet NFPA 211 parging requirements.
Everbrown
Everbrown seals chimney crown cracks with a flexible, weatherproof compound. The rubberized formula expands and contracts with temperature changes while resisting UV degradation. Applied with a trowel, it forms a permanent barrier against water intrusion. The product includes a limited lifetime warranty for ongoing protection.
Raintite
Raintite penetrates masonry surfaces to create a vapor-permeable moisture barrier. The solution protects chimneys, basement walls, and stucco surfaces from water damage while allowing trapped moisture to escape. It bonds permanently with building materials to prevent spalling and efflorescence without altering surface appearance.
Installer Training
Approved Industries offers comprehensive training for chimney professionals seeking certification. The three-day program covers equipment operation, product application techniques, and safety protocols. Graduates receive official certification and marketing support to promote their services as authorized installers of our patented systems.
Questions
What chimney problems do your products address?
Our ceramic coatings solve common issues including cracked flue liners, damaged smoke chambers, deteriorating chimney crowns, water penetration, and masonry spalling. Each product targets specific repair needs while extending chimney lifespan.
Are your solutions suitable for residential and commercial properties?
Yes. Thermocrete handles commercial applications up to 225 feet tall, while residential systems work with wood, gas, oil, and coal-burning appliances. All products meet safety standards for both market segments.
How long do your chimney repairs last?
With proper installation, our ceramic coatings carry limited lifetime warranties. The materials resist thermal expansion damage and maintain performance through freeze-thaw cycles and extreme temperature variations.
Can homeowners apply your products themselves?
No. Our systems require specialized equipment and factory-certified training. We maintain quality control by only allowing authorized installers to purchase and apply our patented solutions.
What safety benefits do your products provide?
Our coatings create gas-tight seals that prevent carbon monoxide leakage, reduce fire hazards from creosote buildup, and contain heat within chimney systems. Certified installations meet national fire protection association standards.
How do your solutions compare to traditional repairs?
Our spray-applied systems complete faster with less structural disruption than traditional relining or tuckpointing. The ceramic barriers resist corrosion better than stainless steel liners and outperform cement-based repairs in flexibility and durability.
