CSI Certified Long Island Chimney Sweep Experts!


Your fireplace or stove can add beauty, warmth and value to your home and set the mood for memorable gatherings of family and friends. But choosing and installing a hearth system without adequate expertise is like playing with fire.

That is why our business is making quality training and credentials its mission.


One of the ways to identify a competent specialist is to check their credentials. The National Fireplace Institute, an independent, non-profit certification agency, has created the standard for certification in the hearth industry. Only those who pass a rigorous examination covering fundamentals of proper installation receive NFI Specialist Certification.
