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 Flint Chimney Sweep Is Delaware’s Preferred Chimney Repair Company
Flint Chimney Sweep has been part of the Garrison Partners family of chimney service companies since 2002, and we run every job in Delaware under The Garrison Standard: written price, clear scope, and a 365-Day Done Right Promise in writing on every repair. That means if a covered repair fails within one full year, we return at no charge. No argument, no re-quote. Delaware homeowners tell us that’s the difference between us and the crews that showed up late, moved the price, and disappeared. We’re background-checked, uniformed, and the phone is staffed by a real person around the clock. Dispatch for Delaware is coordinated from our Cleveland office, and local crews serve the city directly.
When we work on a chimney in Delaware, we know what we’re walking into. The late-1800s and early-1900s brick homes around the Ohio Wesleyan campus and the downtown historic district were built with lime-rich mortar and often no clay flue liner at all. That changes the whole repair conversation. A crack that a bigger-box outfit might shrug off is, in these houses, usually a sign of water already moving through the smoke chamber. Our Chimney Repair team evaluates that before recommending anything.
Chimney Liner Installation in Delaware
Chimney Liner Installation in Delaware means replacing or adding the inner passage that carries smoke and heat safely out of the house. In this city, that conversation comes up constantly, because so many of the older homes near Winter Street and the Northwest Neighborhood have original unlined or clay-tile flues that have cracked after a century of freeze-thaw cycles. We install stainless liners from DuraFlex and cast-in-place systems from HeatShield, chosen by the condition of your flue, not by what earns us a higher margin. A typical stainless liner install in Delaware runs $1,800 – $3,400 depending on chimney height and access.
What the camera shows before we quote
We don’t sell liners sight unseen. Every liner job starts with a Level 2 camera inspection, and you get the photo report. If your flue is in decent shape, we say so. If the tiles are cracked or missing, the photos show that too. The written estimate comes after you’ve seen the same images we saw.
Why Delaware’s old homes need this more often
An unlined flue in a 1905 brick home off West Central Avenue isn’t a hypothetical. Heat transfers through single-wythe brick into the framing of the house, and creosote glazes that we routinely find in these flues burn hot when they ignite. A liner corrects the draft and contains the heat. It’s the single most common repair we recommend after a full inspection, and we recommend it based on footage, not a quota.
Chimney Flashing Repair in Delaware
Chimney Flashing Repair in Delaware means fixing the metal seal where the chimney meets the roofline. When flashing fails, water runs down the outside of the brick and into the attic, then travels down through the smoke chamber and shows up as a damp, musty smell a full floor below the roofline. Delaware’s freeze-thaw winters do a number on flashing. Water gets under the metal, freezes, expands, and pries the seal loose. A standard flashing repair here runs $450 – $900, and full flashing replacement with new copper or steel runs $1,200 – $2,200.
Signs it’s already leaking
Stains on the ceiling near the chimney, peeling wallpaper in an upstairs room, a musty smell that gets worse in summer. Those are Delaware pattern failures, and by the time you notice them, the water has been moving for months. We use copper and steel flashing from Olympia Chimney and Famco, cut and sealed to the roof line, not caulked over the old work and walked away from.
The photo report you keep
Our tech documents the failed flashing before and after. You keep the photos. If water comes back within the year, our 365-Day Done Right Promise covers the return visit and the re-repair at no charge. That’s the guarantee on every flashing job in Delaware, in writing.
Trusted Brands We Service in Delaware
We stock and install parts from brands Delaware homeowners can verify independently: DuraFlex, Olympia Chimney, Famco, and Copperfield. If your existing system uses one of these, we’re already familiar with it and can usually match components without ordering from a distributor. That shortens turnaround for mortar repointing and flashing work in Delaware and keeps the written price closer to the original quote. If you’re not sure what’s in your chimney, we’ll identify it during the inspection and put it in the photo report.
Common Chimney Repair Problems We See in Delaware Homes
- Original unlined flues in the historic brick homes off West Central Avenue and around Ohio Wesleyan. Lime-rich mortar degrades faster than modern Portland cement, and the flue tiles crack and spall. A brush-only sweep misses this entirely; only a camera catches the damage before it becomes a chimney fire or carbon monoxide risk.
- Freeze-thaw crown and flashing failure. Delaware’s winters alternate freeze and thaw enough times that chimney crowns crack, flashing lifts, and water runs down the flue. The telltale sign is a damp smell a floor below the roofline in spring and summer.
- Second- and third-degree creosote glaze in older masonry flues. A standard brush won’t remove glazed creosote from a century-old square flue. Homeowners who skip inspections until spring can have a chimney fire already smoldering in the upper flue by February.
- Spalling firebox brick and mortar. The firebox in a Delaware brick home absorbs decades of heat cycling, and the face brick eventually pops and crumbles. We repair with HeatShield and repoint joints to match the original lime-mortar color.

FAQs About Chimney Repair in Delaware
Once a year, before burning season, regardless of how often you use the fireplace. Delaware’s freeze-thaw cycle puts more stress on crowns and flashing than most Ohio cities because of the temperature swings through late fall. An annual camera inspection costs less than one mid-winter crown rebuild. Call (830) 251-4560 to schedule yours.
First-degree creosote is dusty soot and brushes off. Second-degree is flaky and harder to remove. Third-degree is a glazed, tar-like coating that won’t come off with a standard brush and is a serious fire risk. It matters in Delaware because our older homes with unlined or clay-tile flues run hotter than modern stainless systems, so creosote glazes faster here. We remove glazed creosote mechanically and document the after-photos.
In almost every case, yes. An unlined flue in a Delaware brick home from the early 1900s allows heat and carbon monoxide to move directly through the brick and into interior wall cavities. A properly installed stainless liner like DuraFlex corrects the draft and contains the fire. We’ll show you the camera footage and the written quote before anything is ordered.
You can wait, but you’ll be paying for more damage in the spring. Each freeze-thaw cycle forces water deeper into the crack and widens it. By spring, a cracked crown that would have cost $700 to rebuild might be a $3,500 partial rebuild with water-damaged brick. If the leak is active, fixing it in the fall is the cheaper path.
No. We book a scheduled window, arrive inside it, and never promise a dispatch time we can’t honor. Emergency repairs for active water intrusion or a known chimney fire risk get highest priority, but we don’t run same-day promises. Call (830) 251-4560 and a live person will tell you the next honest opening.
