All chimneys should be checked at least once a year. Checking chimneys for obstruction, creosote build-up, deterioration and overall condition is the best way to insure your chimney will meet your winter venting needs.


Creosote builds up on the interior surfaces of your chimney during normal use, and is a by-product of woodburning. As a general rule of thumb, masonry chimneys serving open fireplaces or woodstoves should be cleaned after one to two cords of wood is burned, and pre-fab metal chimneys should be cleaned after each cord. The actual frequency of cleanings depends on the users burning habits, wood condition, chimney construction, and frequency of use. Even with these guide-lines chimneys vary greatly in design and performance, and every chimney should be checked annually.

Harry will do a complete written evaluation of the condition of your system, and determine if it needs to be cleaned. If so, Harry will drop-cloth off his work area, bring in his huge dustless vacuum to keep your house dust free during the cleaning, and will begin the thorough cleaning process. After the cleaning he will fill out a level-one inspection with a 21-point checklist and written evaluation report. Video inpections available as well.


Harry has a passion for chimney safety, and will make sure the job is done right. Afterwards he will tell you exactly what he found, and make any suggestions for better burning habits or other actions that will reduce your creosote problem. If he's there servicing your woodstove, he'll take the time to make sure you know how to operate it properly, and answer any questions you may have.

"I scheduled an inspection [with a different chimney sweep company] on my property which houses a total of 5 fireplaces in three homesteads. The first company that came out stated there were zero (0) liners in any of the chimneys and just to fix two of them would be $3500. To fix all, well you can imagine. We approached a neighbor who used Frederick Co Chimney Sweeps and they came highly recommended. To our surprise, when Harry came out he told us one chimney did have a liner, was cleaned and now in working order for a little over a hundred dollars."  - Deborah G. - (5 Stars)
