One or more refractory panels (the 1-inch thick fireproof panels lining the fireplace) had minor cracks or deterioration. This is common, and is typically not a concern until cracks exceed 1/4 inch in width, or surface pitting becomes extensive and deeper than 3/16 inch, or if any piece of the refractory larger than 2 inches in radius and 3/16 inch deep becomes dislodged. Monitor refractory panels in the future for further deterioration. When necessary, a qualified contractor should repair or replace refractory panels.
The gas supply shut-off valve for the “log lighter” burner was inside the fireplace’s firebox. The valve may be inaccessible in the event of a malfunction or a blaze inside the firebox. This is a potential safety hazard.Such valves should be located outside the firebox, but close enough so that you can operate them while igniting the log lighter.
This is a picture of a solid wood burning fireplace. The hearth is made of a non combustible material. However, the hearth only extends 15 inches from the fireplace and does not extend at least 8 inches beyond the sides. This can create a safety hazard. When the glass door is opened hot embers could fall beyond the heart onto a combustible surface and cause a fire. Recommend a chimney professional extend the hearth to at least 16 inches in front of the fireplace and 8 inches beyond since the fireplace is less than 6 square feet.
I read the article titled Hearths and Hearth Extensions. Hearths and hearth extension are meant to keep fires from spreading beyond the fireplace. If a fireplace opening is less than 6 square feet, the hearth should extend at least 16 inches in front of the fireplace and 8 inches to the sides. If the fireplace opening is greater than 6 feet, the heart should extend at least 20 inches in front of the fireplace and 12 inches to the sides. Hearth and hearth extensions must be made of non combustible materials. The hearth should be a minimum of 2 inches thick.
I read the article on Wood-Burning Stoves. I found it interesting that wood-burning stoves seem to be safer and get higher acceptance and recommendation than ventless (or vent free) fireplaces. Ventless fireplaces often boast very high efficiency ratings and are promoted as very safe fireplace options. I found the article helpful in reviewing the Do’s and Don’ts of wood burning stove safety. These are helpful tips to pass along to homeowners. The explanation of the differences between catalytic and non-catalytic stoves was also helpful. I especially appreciated the signs to look for that may indicate that the wood burning stove is operating with less than optimal efficiency and could in fact present an unsafe environment to the homeowners. These also will be good tips to present to clients.
This is an image of a vent pipe with a rusting storm collar. This small piece of metal works to shed water away from the base where the pipe protrudes through the roof. Water will penetrate any obstruction through the roof and cause problems to the roof so shedding water off is essential to keeping the roof moisture free.
A chimney can be the most vulnerable and dangerous part of the homes structure. The size and make-up of a chimney can create very dangerous conditions during times of high winds or during an earthquake. Chimneys should be inspected for cracks, chipping mortar, tilting, mechanical defects and missing or damaged lateral support.
This is a fan and combustion air intake for a gas fireplace on a previous inspection. I noticed that there were two switches inside next to the fireplace. One was the ignitor and the other for the fan. With the fan turned on, I could hear the blade hitting the cover, possibly due to a bearing. I recommended further evaluation by a licensed professional.
I read the article on fireplace fuel. I learned what is good to burn such as dried wood and what not too such as wet wood with 21% moisture or more. I was astonished to learn that one 12 foot 2x6 of pressure treated is enough to kill 250 adults.
The chimney cap and screen is required on the roof or exterior of the fireplace. The exterior of the chimney siding and trim must be in good shape and sealed properly. Water penetration into the chimney can cause a lot of damage to the frame work.
i think it is important to inspect the chimney inside and out for any kind of problems. dirty chimneys can cause internal fires inside the chimney and you are unaware of this witch can cause your house to burn down.
Chimney Inspection
An exterior inspection of the home found a type B vent with a chase surrounding it. The vent was connected to a prefabricated fireplace.
Chimney Observations
As the picture shows, the chase lacked both flashing and counterflashing. As such, the roof was at risk for moisture penetration. The client will be informed of this defect…
In the article entitled Firestops by Nick Gromicko and Kenton Shepard, the topic of firestops, which are passive fire protection measures, was covered. The first fact I learned about firestops was that firestops are found in firewalls, which separate the garage from the rest of the house, the attic and the living space, and often between condominium or town house units. Any penetration of a firewall must be sealed with a firestop. The next fact I learned was that firestops are often made of a special mortar that contains certain aggregates. The next fact I learned was that intumescent materials, which expand when heated, are often used to make firestops. The final fact I learned was that when cables that penetrate an intumescent firestop burn away, the remaining intumescent material will expand, due to the heat of the fire, and fill the gap left by the cables. As a result, intumescent firestops are self sealing.
Aluminum siding was most commonly used between 1940 and 1970. This siding material can last from 40 years to the life of the structure and can be repainted for aesthetical reasons. The use of the material has dissipated primarily because of the cost reduction in vinyl siding which is an almost identical engineering design to aluminum but of different material.
Upon visual inspection of chimney, no step flashing is visible at shingles and no counter flashing has been installed. The chimney cap is missing concrete and the brick shows signs of severe spalling. The rain cap is not securly fastened to structure. Correction by a mason contractor is recommended.
Paying extra attention to details during a chimney inspection is necissary to complete a thourough observation of any defects present. Any defect should be reported as it could potentially be costly to repair for a new owner to bear and the potential dangers some defects can lead to unnecissary and avoidable tragidies.
At first glance, this forty-five year old chimney appears to have issues of concern, but a closer look and inspection begs to differ. The efflorescence is minor and far apart. The mortar joints are solid throughout and full ; they are , simply put , dirty. With a sponge and tap water , I was easily able to wipe clean most of the discoloration from the years of neglect. With a mild cleaning solution, this chimney can look good again.
One of my most valued tools is a Smart Level. It was given to me as a gift almost twenty years ago and I treasure this tool. This four foot level has saved many a day by inspecting form work before pouring concrete in critical handicapped accessible areas.
The fireplace appears to be poorly maintained. It has considerable amount of ash on the hearth. It was undetermined whether cracks were present in the firebox because of the amount of creosote buildup in it. Because of these reasons, a specialist is recommended for cleaning and inspection for further evaluation.
In this picture, you will observe some efflorescence on the floor of a basement. It appears that the TPR Value has been activated on the water heater or had a previous leak. Drip pipe was not leaking at the time of the inspection. Inspector recommends cleaning the efflorescence off the floor with an acidic solution or scrubbing with water and a brush. Inspector also recommends checking with the homeowner to confirm the TPR Value has been fixed.
