A Chimney should provide a smooth passage for smoke and gases from fireplace, stove or furnace to flow to the outside. The National Fire Protection Association (NFPA) recommends inspecting chimneys, fireplaces and vents once a year in order to keep them fully functional.

A chimney cleaning company can not only brush soot out of a chimney, but also evaluate its effectiveness and suggest any repairs. When you hire a chimney company, below are some questions you should ask to ensure that the person is credible:
Chimney sweep should have taken certification courses by one of the institutes such as Chimney Safety Institute of America (CSIF), National Fireplace Institute (NFI) or Fireplace Investigation, Research and Evaluation Service (F.I.R.E.).

In addition to certification, make sure they have a license and a valid insurance to protect your home against accidents.

Ask how long has the company/person been in business?

To begin your search, ask your neighbors for contact information of a sweep whose services they may have used. Or ask the sweep themselves for references.
Does the company have unresolved complaints filed within the city or state consumer protection agency or Better Business Bureau?

A trained and experienced professional should be able to assess a chimney’s condition, safety and performance. It is important to choose the professional wisely because proper care and attention to service can help protect people from unnecessary fires and carbon monoxide poisonings.
