FAQ

Q. How often should I have my chimney cleaned?

This a tougher question than it sounds. The quick simple answer is: The National Fire Protection Association standard 211 says, "Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary." This is the national safety standard and is the correct way to approach the problem. It takes into account the fact that even if you don't use your chimney much, animals may build nests in the flue or there may be other types of deterioration that could make the chimney unsafe to use.

The Chimney Safety Institute of America recommends that open masonry fireplaces should be cleaned at 1/4" of sooty buildup, and sooner if there is any glaze present in the system. Factory-built fireplaces should be cleaned when any appreciable buildup occurs. This is considered to be enough fuel buildup to cause a chimney fire capable of damaging the chimney or spreading to the home.

Q. My fireplace smokes. What can I do?

There are a multitude of reasons for smokey fireplaces. We have included an entire section on smoking fireplaces in the fireplace area and we suggest you go there for a better discussion of this problem.

Q. My fireplace stinks, especially in the summer. What can I do?

The smell is due to creosote deposits in the chimney, a natural byproduct of wood burning. The odor is usually worse in the summer when the humidity is high and the air conditioner is turned on. A good cleaning will help but usually won't solve the problem completely. There are commercial chimney deodorants that work pretty well, and many people have good results with baking soda or even kitty litter set in the fireplace. The real problem is the air being drawn down the chimney, a symptom of overall pressure problems in the house. Some make-up air should be introduced somewhere else in the house. A tight sealing, top mounted damper will also reduce this air flow coming down the chimney.

Q. When I build a fire in my upstairs fireplace, I get smoke from the basement fireplace.

This has become quite a common problem in modern air tight houses where weather proofing has sealed up the usual air infiltration routes. The fireplace in use exhausts household air until a negative pressure situation exists. If the house is fairly tight, the simplest route for makeup air to enter the structure is often the unused fireplace chimney. As air is drawn down this unused flue, it picks up smoke that is exiting nearby from the fireplace in use and delivers the smoke to the living area. The best solution is to provide makeup air to the house so the negative pressure problem no longer exists, thus eliminating not only the smoke problem, but also the potential for carbon monoxide to be drawn back down the furnace chimney. A secondary solution is to install a top mount damper on the fireplace that is used the least.

Q. I heat with gas. Should this chimney be checked too?

Without a doubt! Although gas is generally a clean burning fuel, the chimney can become non-functional from bird nests or other debris blocking the flue. Modern furnaces can also cause many problems with the average flues intended to vent the older generation of furnaces. We suggest you check the areas on gas and carbon monoxide for more information.

23,600 REASONS TO HAVE YOUR CHIMNEY SERVICED

The U.S. Consumer Product Safety Commission, reports that some 23,600 residential fires in the 50 states were related to solid fuel appliances and equipment in 1996. An additional 5,500 fires were attributed to chimneys and chimney connectors serving heating systems burning liquid and other fuels. As a result of these fires, 130 people died, 230 people were injured, and total property losses were set at more than $184.4 million.

In addition there were a minimum of 119 deaths from carbon monoxide and at least 4,700 "injuries" reported for the same time frame, though most estimates range much higher.

The root cause of most of these losses is that most U.S. homeowners are unaware that chimneys are an integral part of a home heating system and that they require regular evaluation and maintenance. In a great many European countries - including Sweden, Norway, Denmark, Finland and Germany - chimney-fire damage statistics have been reduced to negligible numbers because national coalitions of government, insurance companies, fire and building officials, and chimney sweeps have developed tough regulations mandating regularly scheduled chimney inspections and cleaning.

The citizens of those countries understand the hazards of unmaintained chimneys, and their chimney sweeps are regular members of their home safety team.

Most homeowners in the U.S. and Canada, however, seem to have little working knowledge of chimney and venting systems. This situation is complicated by the fact that faults, damage and problems rarely visible to the casual observer. In fact, people who will quickly replace a faulty automobile exhaust system because of the hazard it presents will allow their home's exhaust system the chimney or vent - to go unchecked and unmaintained for years. The threat of chimney fires and unsafe indoor air quality conditions can be greatly reduced, perhaps even eliminated, if homeowners only understood that chimneys are active home operation systems which require regular maintenance.

HOW TO CHOOSE A CHIMNEY SWEEP

What a Homeowner Should Know

The chimney service trade is not regulated, nor are chimney sweeps licensed in most states. Further, opening a chimney service business requires a relatively small capital investment. Thus, virtually anyone - without education, training , experience or even a working knowledge of proper tools or equipment can become a chimney sweep. As a result, many ill-equipped, ill-prepared individuals are free to offer their "services" to homeowners. in some cases, these individuals will take advantage of learning opportunities and become competent, qualified sweeps. In other cases, they will continue along the same path they started on, offering incompetent service and, in some cases providing trusting homeowners with a false sense of well-being. For this very reason, a number of states are currently considering license requirements for chimney sweeps. As precursors to state licensing, some municipalities currently license chimney sweeps and in most of those, the criteria for licensing is the CSIA Certified Chimney Sweeptm credential.

Is the company a member of the National Chimney Sweep Guild (provides access to ongoing education)
