Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Alcott Chimney Sweep Is Delaware’s Preferred Chimney Inspection Company
We’ve worked on Delaware homes since 2002 as part of the Threshold Group family, and the city’s split housing stock means we see two very different inspection profiles in the same day: 1880s brick Victorians near Sandusky Street with oversized coal flues, and 2000s colonials off Glenn Parkway with factory-built fireplaces. As our Chimney Sweep in Delaware, we know these homes inside and out. Delaware homeowners tend to ask the same pointed question: “How do I know your inspector is who you say they are?” That’s exactly the question we built our process around. Every technician passes a background check and identity verification before they’re ever assigned to a Delaware job. That’s the Threshold Standard, not an add-on. You’ll know the technician’s name and see their photo before we arrive, and they’re required to show a photo ID badge at your door. Every time, no exceptions.
Our pricing works the same way. Written price before any work starts, always included, never negotiable. And every repair comes with a written guarantee. If it fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies on every Delaware inspection we complete.
Level 2 Chimney Inspection in Delaware
A Level 2 Chimney Inspection in Delaware is the most common inspection we perform on older homes in the historic core and on any property changing hands, and it typically runs $249 – $389. It includes everything in a Level 1 plus a camera sweep of the entire flue interior, which is where Delaware’s coal-conversion problem shows up. When a 1920s chimney was sized for a coal furnace and later hooked up to a modern gas appliance, the flue is often two or three times too large for the exhaust volume. That causes rapid cooling, acidic condensation, and accelerated tile-liner failure, conditions a visual-only inspection misses. Our Chimney Inspection team uses a camera to document exact liner condition so you see what needs attention before you write a check.
What One Delaware Inspection Typically Finds
In the older sections of Delaware, we commonly document spalled clay tiles, shifting liner sections, and first-degree creosote at the smoke chamber on a converted gas flue. On newer construction, we’re more likely to find minor installation gaps, missing rain caps, or manufacturer-specified clearance issues.
When Your Delaware Realtor Requires It
Most real estate transactions in Delaware now trigger a Level 2 inspection, especially in the rental turnover neighborhoods around Ohio Wesleyan University where fireplaces were sealed off decades ago. If you’re buying, selling, or refinancing, this is the inspection level the paperwork usually names.
Chimney Leak in Delaware
A Chimney Leak in Delaware is rarely just a flashing problem, and on older masonry chimneys near the Olentangy River it’s frequently a crown or mortar joint issue that’s built up over years of seasonal ground moisture. We diagnose the source using a camera inspection and a water test, then document what we find with photos before quoting a fix. Cost to address a chimney leak in Delaware typically runs $225 – $650 depending on whether the cause is a deteriorated crown, failed flashing, or cracked mortar joints that need repointing.
Freeze-Thaw Damage on Delaware Masonry
Central Ohio doesn’t get sustained deep freezes, it gets repeated freeze-thaw cycles all winter. Water penetrates micro-cracks in the clay tile or mortar, freezes, expands, and spalls a little more material each time. That’s why so many Delaware chimneys show progressive deterioration from the top down rather than a single structural failure.
Old Riverbed Grounds, Porous Chimneys
Properties near the Olentangy River sit on ground that breathes moisture seasonally, and older brick chimneys absorb that moisture through their foundations. Efflorescence, the white mineral staining you see on some river-side Delaware chimneys, is a warning sign that water is moving through the masonry and will eventually reach the flue liner.
Trusted Brands We Service in Delaware
We install and service the same trade materials chimney professionals specify: DuraFlex liner systems, HeatShield resurfacing, Famco caps and dampers, Copperfield chimney products. When a Delaware chimney needs a new liner or a crown replacement, we’re not improvising with whatever fits; we’re ordering exact-spec components rated for your appliance and flue dimensions. For most Delaware jobs, we maintain local parts stock and can complete relines or repairs in a single visit without waiting on a specialty order.
Common Chimney Inspection Problems We See in Delaware Homes
- Coal-era oversized flues on gas conversions. The original masonry chimney was built for a coal furnace producing far more exhaust volume than a modern gas appliance. The oversized flue cools exhaust too quickly, condenses it into acidic liquid, and eats the clay tile liner from the inside out.
- Freeze-thaw spalling on older brick. Delaware’s frequent winter thaw cycles are harder on mortar joints than a sustained deep freeze would be. Cracked joints let water into the chimney system, which widens the damage every season it goes unrepaired.
- Sealed-off fireplaces in rental housing. Around Ohio Wesleyan University, many older homes had fireplaces decoratively boarded off, and behind those sealed cleanouts we regularly find collapsed liner sections or missing liners entirely. This usually surfaces during a transaction inspection.
- Efflorescence on riverside masonry. Seasonal Olentangy River ground moisture wicks into brick foundations and older chimneys, carrying dissolved salts that crystallize on the surface. It’s not just cosmetic; it tells us water is moving behind the brick and attacking the liner.

FAQs About Chimney Inspection in Delaware
A standard sweep removes creosote and debris, but a Level 2 inspection uses a camera to see inside the flue itself, and that’s where coal-era converted chimneys hide their damage. If your home off West Central Avenue or Sandusky Street was built before 1940, the flue was almost certainly oversized for a coal furnace and later converted to gas without relining. A Level 2 documents what’s actually happening inside so you’re not guessing. Call (336) 863-3889 to book one.
Yes, and in Delaware it’s often urgent. Homes around Ohio Wesleyan University and the older rental districts frequently had fireplaces enclosed for decoration or to stop drafts, but behind those sealed cleanouts we regularly find collapsed or missing flue liner sections. If the chimney is attached to a furnace or water heater vent, a failed liner behind a sealed fireplace is a carbon monoxide risk that a visual check won’t catch. We can camera the flue without opening up the fireplace in most cases. Call (336) 863-3889 for a free estimate.
Seasonal ground moisture near the river raises the water table under older homes, and brick chimneys absorb that moisture from the foundation upward. It accelerates efflorescence, mortar erosion, and crown cracking on riverside properties in a way you don’t see as much a mile or two inland. If you’re within a few blocks of the river and noticing white staining on the chimney, that’s the reason. A camera inspection will show whether the moisture has reached the flue liner. Call (336) 863-3889.
Creosote is primarily a wood-burning byproduct, and it forms when exhaust cools too quickly and condenses. An oversized coal-era flue on a gas appliance creates exactly those cooling conditions, so even a chimney that has only ever burned gas can develop a sticky, tar-like creosote deposit in the smoke chamber. We’ve documented first-degree creosote on gas-converted flues in Delaware’s historic core more than once. It’s a chimney fire risk even without a wood fire. An inspection will tell you if it’s present. Call (336) 863-3889.
Factory-built zero-clearance fireplaces in homes off Glenn Parkway, Houk Road, and the newer Delaware County subdivisions need inspections just as much as masonry chimneys, even though they’re built differently. We check for installation clearances, refractory panel cracks, proper termination caps, and flue pipe alignment. Most manufacturers recommend an annual inspection, and many warranties require one. The inspection is cheaper than a replacement firebox. Call (336) 863-3889 for a free estimate.
If your Delaware chimney hasn’t been looked at in a few years, or you’re buying a home and the inspection got flagged, call (336) 863-3889 for a free estimate. Our Chimney Inspection team serves all of Delaware and the surrounding area, and we answer every call with a live person.
