How often should my chimney be swept?

The NFPA 211 standard recommends every chimney be inspected at least once a year, and swept whenever soot buildup reaches 1/8 inch or any glaze is present. Most households that burn wood regularly need a sweep every year.

Are you really available 24/7?

Yes. All three offices — Kansas City, Dallas, and Chicago — answer around the clock, every day of the year, for both emergencies and regular appointments.

How long does a chimney cleaning take?

A standard sweep with a Level 1 inspection usually takes 45 to 90 minutes, depending on the condition of the flue and the type of appliance.

Will it make a mess in my home?

No. We lay drop cloths, wear shoe covers, and run HEPA-filtered vacuums the entire time. Your hearth is left cleaner than we found it — that is our no-mess guarantee.

Are your technicians certified and insured?

Every technician is background-checked, trained to NFPA 211 guidelines, and fully licensed and insured in Missouri, Texas, and Illinois.

Which areas do you serve?

We serve the greater Kansas City metro, the Dallas–Fort Worth metroplex, and Chicagoland from our three local offices.
