Poquoson Chimney Inspections: Protecting Your Home from Coastal Weather & Creosote
My wife keeps telling me to stop talking about soot at the dinner table. We will be sitting there eating meatloaf and I start drifting off thinking about a rusted damper I saw earlier that day off Little Florida Road. She catches me staring at the wall and knows exactly where my head is at. She says Ray, leave the work in the truck. But after 11 years of crawling onto roofs all over Poquoson, it is hard to turn it off.
I live right off Wythe Creek Road. I drive the same streets you do. I see the same weather hitting our houses. And tonight I am sitting here at my kitchen table, tired as heck, deciding to write this down because I want to save you guys some grief this winter.
The Christmas Eve Disaster on Poquoson Avenue
Let me tell you a story that sticks with me. A few years back, the Hendersons over on Poquoson Avenue called me. It was Christmas Eve. I was literally putting on my boots to go to my in-laws’ house when the phone rang. Panic. Absolute panic on the other end of the line.
They had lit a fire for the holiday. It was supposed to be cozy. Instead, their living room was filling up with smoke and they could smell something hot and chemical that definitely wasn't pine wood. I told my wife I had to go. She wasn't happy but you don't leave a neighbor with a potential chimney fire.
I got there and got things under control. Once the smoke cleared out and things cooled down enough for me to run a camera up there, I saw it. They had three inches of glazed creosote choking that flue liner. Three inches. It looked like someone had poured roofing tar down the chimney and let it harden.
Here is the kicker. Mr. Henderson looked me in the eye and said they barely used the fireplace. Maybe three times a year. He couldn't figure out how it got that bad. I had to bite my tongue pretty hard. I didn't want to ruin his Christmas by lecturing him right then. But the truth is that "barely using" a fireplace is how some of the worst buildup happens. You light a small, cold fire. The flue is cold. The smoke condenses instantly. It layers up. If he had waited one more hour to call me, we would have been talking to the fire department instead of me.
Why the Bay Hates Your Chimney
Poquoson is beautiful. I love living here. But being this close to the Chesapeake Bay is brutal on masonry and metal. If you lived in Richmond, maybe your chimney cap lasts you 10 or 15 years. Here? I am seeing caps rot out in 5 years. Sometimes less.
It is the salt in the air. You know what it does to the undercarriage of your truck. Well, it does the exact same thing to your chimney cap and your chase cover. I replace more caps in Poquoson than any other town I service. The wind blows that salt spray right off the water and it just eats the metal. Once that cap rusts through, rain gets in. Then you have water dripping onto your damper, rusting that out too. Next thing you know, you are getting water behind the firebox.
The humidity here is another killer. We live in a swamp, basically. That moisture in the air affects how your wood burns. Fires here tend to burn cooler because the air being drawn into the firebox is heavy and wet. A cooler fire doesn't send smoke up and out quickly. It lingers. That lingering smoke cools down as it rises and turns into creosote. It is a cycle that happens way faster here than it does out west.
What I Actually Look For
Some people think an inspection is just me shining a flashlight up the hole and giving a thumbs up. That is not it. When I come out to your house, I am bringing a camera system that goes all the way up. I am looking at things you will never see from the ground.
I check the flue liner first. I am looking for cracks. Even a hairline crack can open up when it gets hot, and that lets heat transfer to the wood framing of your house. That is how house fires start inside the walls. I check the damper to make sure it seals tight so you aren't paying to heat the outside.
Then I go up top. I check the crown. That is the concrete slab on top of the bricks. If that cracks, water pours right down into the brickwork. I check the flashing where the chimney meets the roof. But honestly, around here, I am also looking for critters.
The raccoons around Little Florida Creek seem to think chimneys are luxury condos. I have pulled more nests out of flues in that neighborhood than anywhere else. If you don't have a cap with a heavy-duty screen, a raccoon is going to move in. They block the airflow. Then you light a fire in October and smoke out your whole downstairs because the chimney is plugged with twigs and angry animals.
Let’s Talk About Creosote
I mentioned creosote earlier with the Henderson story. Here is the simple version of what that is. When you burn wood, it releases smoke, water vapor, and unburned wood particles. As that stuff flows up into the cooler chimney, it condenses into a residue. That is creosote.
It starts out flaky and soot-like. That is Stage 1. It is easy for me to brush out. If you leave it, it turns into crunchy tar flakes. That is Stage 2. If you still ignore it and keep burning, it turns into Stage 3. This is a thick, shiny glaze that looks like hardened molasses. Stage 3 is basically concentrated fuel. All it takes is one spark or a fire that gets a little too hot, and that stuff ignites. A chimney fire sounds like a freight train running through your living room. It burns at 2,000 degrees. It can destroy the chimney liner and catch the roof on fire.
The NFPA 211 code says you need an annual inspection. That isn't just government talk. It is the only way to catch this stuff before it hits Stage 3. Once it is glazed, I can't just brush it out. I have to use chemicals and special chains to beat it off the liner. It costs you way more money and it is a huge headache.
Nor'easters and the Freeze-Thaw Cycle
We get those nor'easters that blow rain sideways. I see it bad down by Messick Point. The wind drives rain into every tiny crack in your brick and mortar. Then the temperature drops at night and that water freezes.
When water freezes, it expands. It pops the face right off the bricks. We call it spalling. If you see bits of red brick laying on your roof or on the ground near the chimney, that is bad news. It means your chimney is slowly falling apart from the inside out. I get calls every single time we have a big freeze after a storm. People see chunks of masonry in the yard and freak out.
If we catch those cracks early, I can seal them. I can apply a water repellent that lets the brick breathe but keeps the rain out. If you wait until bricks are popping off, we are talking about tearing down and rebuilding. That is expensive.
Just Get It Done
Look, I am not trying to scare you. I just want you to be safe. I want you to be able to light a fire this winter without worrying about what is happening inside that dark tunnel going up through your roof.
If your chimney hasn't been looked at since last winter, or if you can't remember the last time a sweep was out there, just get it done. It takes me about an hour. I keep it clean. I lay down drop cloths. You won't even know I was there, except you will know your house isn't going to burn down.
I’ve got to get some sleep. The wife says I have an early day tomorrow, and she is right. Stay safe, Poquoson.
