Frequently Asked Questions

Q. How often should I have my chimney cleaned?
This a tougher question than it sounds. The 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 1/8" 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 stinks, especially in the summer. What can I do?
The smell is due to creosote deposits in the chimney, a natural byproduct of woodburning. 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.

Q: What is level 3 creosote?
I have an 80 year old home that was a longtime rental house. I have lived here five years and have been using the fireplace for four of those years. I do not know how long it has been since my chimney was swept (potentially decades, if ever). I just had a chimney sweep at my house and he informed me that the creosotein my chimney was quite thick (he used the term "level 3" creosote). He also said that in the smoke chamber, the brick is stepped (instead of smooth) and that there is a lot of dangerous buildup in there. He recommended two applications of an acid cleaning (which he said are not entirely foolproof, and work better above 45°F) and that we use a chemical when we burn our fire to help "chalkify" the creosote buildup. He showed me the buildup inside with a light and everything he said seemed to make sense. Does this sound like it's on the up and up? I can't find any info on this acid cleaning and I would like to know if this sounds like it is the proper course of action in a case like mine.
What you have described sounds pretty typical. In addition to the chemical treatment that you mentioned, professional-grade chemicals, usually in the form of a powder, can be applied by chimney sweeps to help change the nature of the glazed creosote to a form that can be removed by a professional with a brush Both forms of these products require some heat such as you would find in a small fire in the fireplace.
If the creosote is gummy, about the only way to deal with the creosote is with a chemical treatment or with an acid application. Acid applications are not as commonly used since they are harder to apply and have to be neutralized a few days after application. If the creosote is crusty or fractures when hit (as opposed to gummy) a rotary cleaning can be helpful. Read our position statement on chemical chimney cleaning products here.

Q: How do I know if he really cleaned my chimney?
In the past, sweeps we've hired have always gone on the roof, checked the flashing, the mortar and all the workings of the chimney and then cleaned the chimney from the top of the house. Today, this sweep came in, looked into my fireplace from the bottom and said we don't need it clean because he can still see the bricks. My asked to have it cleaned anyway. He then grabbed a wire brush and simply rubbed away any buildup from the main opening to the fireplace without even going up into the chimney to clean anything. Am I way off base, or did the sweep charge me without cleaning my chimney?
Your past experiences with chimney sweeps sound as though the sweep did the job he was hired to do. However, your most recent experience sounds a bit odd. If the sweep agreed to do a complete sweeping and only cleaned the brick in the fireplace firebox, you did not get the service that you paid for. A complete chimney sweeping includes the chimney flue and smoke chamber. In the future you could ask for a Level 1 chimney inspection and a chimney sweeping. If the sweep doesn't know what a Level 1 inspection is, find one that does. A Level 1 inspection is detailed in the National Fire Protection Association 211: Standard on Chimneys, Fireplaces, Vents and Solid Fuel-Burning Appliances.

Q: How common is it that chimney liners cannot be seen from inside the fireplace using only a flashlight?
Is there some standard building requirement for the flue and the fireplace that you can't just look up from the fireplace and see the sky or chimney cap at the top of the chimney? Flues are allowed to have up to 30 degree offsets. In most cases this will make a direct visual observation of the flue impossible. A video scan would be required to evaluate the flue condition. The height of the chimney flue is not a factor. There is a big difference in what is observed between a visual inspection and a video inspection, even in short flues.

These FAQs are a few that we are asked.

I have water leaking into my fireplace and I also have water stains on the ceiling and the wall around the fireplace. Can your company fix my problem?
We will complete a thorough inspection to determine where the water is coming from & and help in the prevention of further leaks. Sometimes the problem is not chimney related.A roof problem can show up at the chimney and decieve us. We fabricate and install caps, custom covers,Clay Pots, pre-fab pans, dampers; seal flashing & crowns, install professional water sealants.

Can I convert my gas fireplace into wood burning?
If you have a fully operational fireplace, whether masonry or pre-fab, it would normally be as simple as removing the gas logs & capping the gas line or installing a gas log lighter. But with today's new appliances, direct vent & vent less units would not be set up for solid fuel (wood) & could not be converted to wood burning.

I have birds ('they sound like bats!!!..) in my chimney. What can I do?
The birds in your chimney are called CHIMNEY SWIFTS & they nest 1 or 2 times a year. After their nesting period, your chimney should be cleaned & a cap/cover should be installed on top of your chimney to keep out any animals or debris that could fall down inside. If you already have a cap, you may need the screening around it replaced or repaired.
