Chimney Sweep Service
1. Maintenance of your Chimney:
Chimneys exhaust a number of substances from your home including smoke, soot, water vapor, and creosote. As smoke rises from your chimney, soot and creosote condense on the interior walls causing a build up. If the chimney is not cleaned, the creosote can ignite, causing a dangerous chimney fire of up to 2000 degrees. These fires can damage the chimney and set surrounding combustibles of your home aflame.
2. Chimney Sweep:
The Chimney Safety Institute of America (CSIA) recommends having your chimney and fireplace inspected yearly and cleaned if needed. Our trained sweeps will put a drop cloth on the floor, and a vacuum will be turned on and running inside the firebox. The soot and creosote deposits are scraped off the walls of the flue and the smoke chamber with brushes attached to flexible poles. The damper, smoke shelf and hearth are cleaned of any debris. Our methods to insure that there is no mess in your home, in fact we guarantee it. The cleaning may take up to an hour, and should be done every one to three years depending on use, or when you move into a new home. A visual inspection of the interior and exterior areas of the chimney, including the crown, flue, and flashing is also performed. If there are problems with your system, they can be noted on our written condition report, provided to you after every cleaning and inspection (if requested).
3. Chimney Inspections:
The inspections of chimneys are an important service. Chimney inspections come in many forms and you should be aware that not all inspections are alike. Dansville Town and Country Agway’s chimney sweeps follow the National Fire Protection Association (NFPA) recommended inspection procedures. NFPA divides the inspection procedure into three categories, or levels. The circumstances which give rise to the inspection determine what level of inspection is to be conducted. A level I inspection is the most basic level of inspection while level II and level III inspections are progressively more detailed and comprehensive. A level I inspection is completed during each chimney cleaning, or sweeping.
4. Level I Inspection:
A level I inspection is the recommended level when an evaluation of the chimney system for continued service is needed and the conditions of use are not changing. This could include:
- Routine or annual evaluations of the venting system.
- An appliance connected to the system is being replace with a similar appliance
- During chimney cleaning or sweeping
A level I inspection is limited to readily accessible portions of the venting system, and accessible portions of the connected appliance(s) and the chimney connection. The inspector will check the readily accessible portions of the chimney, its enclosing structure, and the flue. A level I inspection includes verification that the flue is not blocked or significantly restricted.
5. Level II inspection:
A level II inspection is more detailed and thorough than a level I inspection and is the recommended inspection when conditions of use for the appliance or venting system are changing, or when a level I inspection reveals the need for a more detailed inspection. Several instances where a level II inspection is specifically recommended include:
- Replacement of an appliance with one of dissimilar type, input rating or efficiency
- Prior to a flue relining
- Upon sale or transfer of the property
- After an even likely to have caused damage to the chimney, such as a chimney fire or other sudden occurrence event
A level II inspection includes all of the requirements of a level I inspection as well as the following:
- Inspection of accessible areas of attics, basements, and crawlspaces
- Accessible areas of the chimney exterior and interior
- Accessible portions of the appliance and chimney connection
- Video scanning, or other thorough inspection, of the flue interior
- Evaluation of the flue lining to determine that its material and sizing is appropriate for the appliances being served
- Proper clearance to combustibles in the accessible areas listed above
- Proper construction and condition of the chimney system in the accessible areas listed above.
While the level II inspection is a rather thorough inspection and requires access to many areas of the building, it does not require removal of permanent parts of the building, such as siding, chase covers or wall coverings.
6. Level III Inspection:
A level III inspection is the most detailed of all the inspection types and includes inspection of the concealed areas of the building. However, examination of concealed areas will be limited to areas reasonably suspected of containing hazards that cannot be evaluated otherwise.
A level III inspection includes all areas covered in a level I and level II inspection, and inspection of concealed areas to investigate known or suspected problems. In as much as certain portions of a level III inspection require destructive action to the building, the inspector will discuss these areas with the building owner prior to the inspection.
9. Video Scanning:
A video scan is where we use a camera system which is lowered into the chimney (or pushed up from the bottom). The camera allows us to inspect the chimney from a range of just a few inches instead of just looking from the top or bottom. The camera image is viewed on a TV monitor by the inspector. Video inspections may be recommended if the customer or sweep suspect certain problems. Video inspections are often recommended after a chimney fire or some other form of damage to a chimney, and are a routine part of a Level II or Level III inspection.
You should be aware that even the most thorough inspection will not reveal all problems. Some areas of a chimney simply are not assessable due to construction of the house. Be sure to discuss any specific concerns with your sweep. The recommended inspection technique will often be based on your comments and concerns. This works similar to a visit to your doctor. Your doctor probably doesn’t do an EKG and take a full set of X-rays during every visit. However, if you tell the doctor you have chest pains he will perform the tests related to that problem.
10. Frequency of Inspection:
NFPA recommends that all chimneys, fireplaces and vents be inspected annually. In addition to this requirement, there are other times when chimney and venting systems should be inspected, such as:
- After any unusual, or sudden occurrence event, such as a chimney fire, lightning strike, or earthquake
- Prior to purchasing a home with an existing chimney
- Whenever changes are made to a chimney or vent system, including replacement of connected appliances
- Prior to major system repairs
