Sweeping a chimney does not “make” it safe…

Don’t be fooled by un-certified cheap chimney sweep service providers.
Sweeping your chimney does not make it safe.
Original construction defects, chimney fire damage, human error and improper use are what make your chimney safe or unsafe

Chimney water leaks from rain? I repair flashing, seal chimneys etc..

News0 comments

I have had hundreds of customers call me for water leaks. Sometimes for specific wind driven rain, sometimes only in winter, sometimes only after long duration rainy days.
Most of the time the finger is pointed at the flashing, the area where the chimney and roof meet.
In may cases, we find tar that has been used in past years to seal the flashing has hardened and then cracked from chimney expansion.
I use an elastomeric flashing repair method that has fiberglass mesh reinforcement within 2 layers of a rubberized compound that will not harden and crack.
I also have experience in diagnosing the many different types and styles of chimney masonry products, bricks, blocks, stone etc.. all have different natural abilities to absorb or repel rain water
Metal pipe chimneys often have a storm collar that needs silicone to prevent water from running down the outside wall of the chimney pipe

Chimney repointing, exterior chimney repairs and other services offered by Mrchimneyman

Spring is the time of year when we dust ourselves off and head back into the yard.
Quite often this is when we find the need for chimney maintenance and repairs as loose mortar pieces or faces of the brick are lying on the roof or in the yard. Most of the time this is a cosmetic problem for many years before it becomes structural and in most cases the problem is a result of improper original crown construction

Pyrolysis- the breakdown of wood or combustible material via the application of heat

News0 comments

The chemical alteration of a solid fuel, from the action of heat alone, in the absence of oxygen and hence, without burning. The products of pyrolysis are gases, vapors and charcoal.

Notes about pyrolysis and spontaneous combustion of wood:

Once sufficient moisture has been removed from the wood, Wood molecules begin to break down due to a process known as pyrolysis, a chemical alteration of fuel molecules as a result of the application of heat. This initial wood pyrolysis, the second identifiable stage in the burning of wood, is crucial to the combustion process since most of the hydrocarbons produced by pyrolysis are in the form of gases or very small droplets of liquid tar. These substances, commonly known as hydrocarbon volatiles, contain roughly 30-50% of the potential energy found in the wood. In order for combustion to occur at this stage, oxygen must become well mixed with the gases given off by the pyrolyzing wood.

The mixture must be hot enough to cause the molecules to collide energetically with one another. In order to achieve complete combustion of solid fuel, temperatures in the combustion chamber must reach 1100 degrees F. Since it is unlikely that the entire firebox will reach this temperature, oxygen must mix with the hydrocarbon volatiles at the hottest area of the firebox. Close to the burning wood. In addition, sufficient oxygen must be allowed into the firebox to provide for oxidation reactions with as many of the fuel molecules as possible.

When wood forming or framework is left on the underside of your firebox or hearth extension, it is potentially subject to pyrolysis, and in time after all moisture and other chemical compounds are driven out of the wood due the application of heat, you are left with charcoal which may ignite spontaneously with temperatures as low as 235 degrees.
