Why Choose Guaranteed?

  • Expertise - This is what we do! We focus 100% of our business on all things chimney related. You could even say we are "chimney geeks".
  • Safety, Safety, Safety! - Your safety is our number one priority. We take no shortcuts. We're your neighbors! The owner and crew live, work and play in Eastern Long Island.
  • CSIA Certified Technicians - You get the guys who know right from wrong. Our technicians have been educated, tested and certified by the Chimney Safety Institute of America. There's more to a simple chimney sweep than meets the eye. An educated technician can spot a potential problem and recommend the correct repair - not just sell you something you don't need.
