Improperly sized chimney caps

January 10, 2019 | A Day in the Life

Already in 2019, I have inspected three homes where a 8″ chimney cap was “installed” into a 10″ flue termination. The obvious is that the person installing these chimney caps knows exactly what is going to happen eventually, along with the water intrusion damage that will occur when it does happen. What isn’t obvious is that a chimney cap was incorrectly installed and even the active water intrusion can be hard to spot until it progresses. This drone image shows a 8″ cap that was at one point installed into the 10″ flue termination. As you can see, the end result is wind removing the chimney cap, sometimes turning it into a giant metal frisbee (huge liability issue). When you are having your chimney cap replaced ask for proof of measurement. This issue could not be seen from ground level (it was blocked by the shroud) and the client was … Continued

A roofing disaster

January 10, 2019 | A Day in the Life

On one of my inspections yesterday, I encountered an absolute mess of a job performed by a roofer I will not mention. A new roof was installed a few months ago without replacing the chimney step and counter flashing and now the deteriorated flashing has started to allow water intrusion into the home. The roofer was called out again and this was the initial fix: 🤦‍♂️ Not only did they not replace the flashing (again), they covered the cracks on the crown with sealant that I now have to remove before correctly repairing the crown. All of this could have been prevented if the job was done correctly in the first place and it would have also prevented the water damage that is now inside of the home.

Dryer Vent Safety

January 6, 2019 | Common Questions

It may not be one of the most exciting things to do (kinda like having your car worked on), but performing regular maintenance on your dryer venting system is essential for safety and also extends the life of your dryer. Consider this, a dryer vent is only four inches wide and even with 1/2″ of buildup around the inside of the vent, your dryer vent is now only flowing through a three inch opening. As the dryer vent becomes more and more restricted, it causes the dryer to work overtime and the additional buildup of lint can easily cause a dryer fire. The danger can be even greater if you are using gas dryer, you now add in the extra hazards of carbon monoxide and potential gas leaks. In summary, always be proactive about dryer maintenance and always make sure a professional is servicing your system such as a CSIA … Continued

Radiant heat and the impact on combustibles

January 6, 2019 | Chimney Basics

So you may have heard me talk about clearances to combustibles once or twice before but here is a quick example of what the heat does to combustibles and how it can start a fire. As heat is absorbed by a combustible, in the form of radiant heat, it slowly breaks down the ignition temperature that is needed to ignite the combustible. the process is called pyrolysis which is the thermal decomposition of a material through elevated heat. Ignition temperature of wood can drop to as low as 300 degrees after long-term exposure to heat! One very key thing to also remember with ignition of the combustible is that it will ignite without any direct contact with flame. Here is a example in fast forward: 1. Initial break down of wood from heat As you can see, the Wood is not touching any flame throughout the timeframe. 2. Ignition temperature … Continued

The dangerous flip

January 5, 2019 | A Day in the Life

As a chimney sweep, you see the good, bad, and dangerous when it comes to chimney work performed before a sale. One of my recent inspections uncovered the dangerous side. The home had recently been purchased from a flipper and the clients were interested in having the fireplace inspected for use this Winter. A home inspection had already been performed with no mention of any issues with the fireplace but here is what I found: Here is the initial overview of the fireplace. Now let’s have a look inside.. Dear lord! The flue system was being held up by a stack of bricks and was on the verge of collapse! Not only was the fireplace unsafe for use, it also was a safety hazard from the possibility of collapse. Now comes one of the worst parts of my job, giving the bad news to the clients. A repair this substantial … Continued

Inspection of the day – Not a good idea!

January 4, 2019 | A Day in the Life

So this was a particularly scary inspection to say the least! The back story is that the client was having issues with water intrusion leaking onto the ceiling around the chimney. Let’s make this one interactive… Starting in the attic I see that getting to the chimney area is not going to be easy! After maneuvering around and crawling on the trusses/insulation, I make it to the chimney. The moisture meter and infrared imaging pick up active water intrusion below the flashing so that part was solved pretty quickly. Now for the scary part.. The chimney was supported by wood framing that had been impacted by the water intrusion and was beginning to come apart! Literally a ton of bricks in the attic that were barely supported from below. Definitely and tough fix and more importantly a life safety concern 🙁 Yet another reason to have your chimney inspected by … Continued

The importance of clean drop cloths

January 4, 2019 | A Day in the Life

As a professional chimney sweep, I do everything in my power to make sure that my client’s home stays spotless throughout the service. One key thing that all chimney sweeps should consider is how often they are washing their drop cloths. Over the years I have seen both ends of the spectrum from fellow sweeps but I personally only use them once before washing them. It only takes one dirty drop cloth to ruin a expensive rug or permanently put a stain on carpet, especially if you have been working with a LP gas system prior. I would recommend looking at a long-term approach and investing in a industrial washer and dryer. This investment will pay off with a steady supply of clean drop cloths for you and your clients.

Fireplace grates in factory built systems.

December 31, 2018 | Common Questions

One interesting aspect of factory built (pre-fabricated) fireplaces is that they are a UL listed and sometimes have very specific requirements for what can and can’t be used. Today we will talk specifically about fireplace grates for factory built systems. Most fireplace manufacturers design the fireplace grate uniquely for the system, factoring in things such as size, height, and placement to help the system function as intended. The data plate and/or instruction manual should have the required information of what replacement grate will be needed. Here is one example of a data plate with the grate information below: I have seen several occasions where a grate has been improperly replaced causing smoke to enter the home or even over firing of the fireplace system! If you ever have any questions, reach out to your local CSIA certified chimney professional or the manufacturer to ensure proper replacement.
