Frequently asked questions
Do you provide free estimates?
Yes — repair estimates are free and written, with photos of what we found and the final price quoted before any work begins.
Will sweeping make a mess in my house?
No. We lay drop cloths, seal the fireplace opening, and run HEPA vacuums the entire time — your hearth stays spotless.
What is a Level 2 inspection and when do I need one?
A Level 2 adds a full video scan of the flue. It's required when buying or selling a home, after a chimney fire, or after any major weather event.
How fast can you get here?
Most North Bethesda appointments are available within a few days, and often same-week even in peak fall season.
My chimney leaks when it rains. Can you fix it?
Yes — most leaks come from a cracked crown, missing cap, or failed flashing. We diagnose the true source and fix it, not just symptoms.
How often should a chimney be swept?
The NFPA recommends an inspection every year and a sweep whenever creosote reaches 1/8 inch. If you burn regularly in North Bethesda winters, that's typically once a year.
Are you licensed and insured?
Fully. We carry liability insurance, and every technician is certified and background-checked.
Do repairs come with a warranty?
Yes — masonry and cap work carries a workmanship guarantee, and waterproofing treatments include a 10-year material warranty.
Do you work on gas fireplaces too?
We inspect and service the venting on gas units as well — flue checks, cap work, and draft problems included.
