The house you almost bought
A young family called us out to their brand-new house last winter. Closed in October. First cold snap in November. Went to light a fire.
Smoke everywhere.
Not a little curl of it — smoke pouring into the living room, the kids coughing, the dog running for the door. They opened windows in freezing weather and called us the next morning.
What we found up there could have killed somebody.
Someone’s previous “repair job” had left the flue partially collapsed — held together with what looked like leftover mortar troweled by hand. A cracked chimney crown was letting water pour down inside the masonry, freezing and thawing, breaking it apart from the inside out. And birds — a whole raccoon-sized nest of sticks and leaves — had blocked the top of the flue so completely that even without the crack, that chimney couldn’t have vented a match.
The home inspector had walked past all of it. Wrote “chimney appears functional” on the report.
The family paid $427,000 for that house. They’re now paying us to rebuild the chimney from the crown down. The seller? Long gone.
What the home inspection actually covers
Here’s what most people don’t realize about the standard home inspection: it does not cover your chimney.
Not really.
A home inspector will look at your chimney the way they look at your roof — from the ground, with binoculars, maybe up a ladder if they’re feeling ambitious. They’ll check that it’s standing. They’ll note if the crown looks obviously cracked. They’ll say whether they can see daylight through anything.
That’s it. That’s the “chimney inspection.”
They don’t climb inside. They don’t run a camera down the flue. They don’t test the draft. They don’t check the smoke shelf, the damper operation, the liner condition, the flashing, the mortar joints inside the firebox, or whether the previous owner’s brother-in-law “fixed it” with silicone caulk and a prayer.
Home inspectors aren’t cutting corners — most are honest, hardworking people doing the job they’re licensed to do. A chimney is just a specialty. It requires different training, different tools, and a different set of eyes. The National Fire Protection Association (NFPA 211) actually specifies that chimneys should get a Level 2 inspection during any property transfer. Almost nobody follows that rule.
Which means it’s on you, the buyer, to protect yourself.
What a real chimney inspection actually finds
When we get called out for a pre-purchase inspection, here’s the short list of what we routinely find on houses that “passed” the general inspection:
Cracked flue tiles. Invisible from outside. Deadly inside — a cracked flue can leak carbon monoxide into the house every time you burn a fire.
Missing or damaged chimney caps. Every unprotected chimney is an open invitation to rain, birds, squirrels, and raccoons. We’ve pulled entire animal skeletons out of flues. We’ve pulled out live raccoons too, but that’s a different story.
Crown deterioration. The concrete slab on top of your chimney. When it cracks, water gets in. When water gets in, everything below it slowly falls apart. A small crown repair now saves a full chimney rebuild down the road — and the difference in cost is not close.
Creosote buildup from the previous owner. If they burned wet wood, or didn’t have it swept, you inherit a fire hazard. Creosote is what causes chimney fires. Real ones — the kind that make the evening news.
Bad prior repairs. Someone applied roofing tar. Someone patched with the wrong mortar. Someone used caulk. We see it all the time. The house is beautiful, the kitchen is remodeled — and the chimney has been quietly failing for a decade.
Missing or malfunctioning damper. Small thing that leaks heat every day you own the house. Adds up.
None of that shows in a walk-around home inspection. All of it shows in ours.
What it costs, and why it’s worth it
A pre-purchase chimney inspection from us runs around what a nice dinner for four costs — versus tens of thousands of dollars in surprise repair bills after closing. And here’s the leverage most buyers don’t use: if we find something serious, you can negotiate. Either the seller fixes it before closing, credits you at closing, or drops the price. That inspection often pays for itself many times over before you even move in.
If everything checks out clean, you get peace of mind and a written report you can hold onto for insurance, resale, and just knowing your family is safe.
Either way, you win.
For the real estate agents reading this
If you’re a Realtor working buyers in Northern Virginia, here’s the straight talk:
Recommending a chimney inspection to your clients before closing does two things. First, it protects them from exactly the kind of surprise the family in our opening story ate. Second, it protects YOU — because when that fireplace smokes up their living room in November and they realize nobody warned them, guess who they call before their attorney?
We work with agents. We turn inspections around fast — usually within 48 hours of the request — with clear written reports you can hand to your clients or attach to the transaction file. We show up in a marked truck, in uniform, on time. No surprises for you, no drama for your closing.
Add us to your preferred vendor list. Call us direct at 703-789-3639, or send your clients to helpmychimney.com. We’ll take good care of them, and by extension, good care of you.
The bottom line
Buying a house is the biggest purchase most people ever make. The chimney is one of the few systems in that house that can literally kill you if it’s broken. Skipping the specialty inspection to save a few hundred dollars on a half-million-dollar purchase is the kind of math that only looks good until it doesn’t.
Get the inspection. Get it from someone whose job it is to inspect chimneys — not from someone whose job includes 40 other things and stops at the roofline.
