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 Devon’s Preferred Chimney Repair Company
We run on a simple code: write down the price, do the work, stand behind it for a full year. That is The Garrison Standard, and it is how our Chimney Repair crews operate on every job in Devon, no exceptions. Homeowners here have told us they have been burned by chimney companies that quote one number on the phone and another at the door. We do not do that. The number we write before the job is the number on the invoice.
Our technicians are background-checked and uniformed. When you book a repair, you know exactly who is walking through the door. Hank Delano leads our crews, and he holds the same expectation on every call: arrive inside the window, protect the floors, and do not leave until the before-and-after photos are in your hands. Devon homeowners appreciate that discipline. It is why they call us for the second chimney, or the rental property, or the mother-in-law suite.
We are part of Garrison Partners, a family of independently owned chimney service companies founded in 2002. That means we have access to professional-grade materials and a network of technical support, but we operate locally. When your chimney needs work in Devon, the people who show up know Devon.
Chimney Masonry Repair in Devon
Chimney Masonry Repair in Devon is the work that gets called when freeze-thaw cycles have had their way with your chimney. Water gets into tiny cracks in the crown or the mortar joints, freezes, expands, and pries those cracks open wider. Repeat that for a dozen winters on a stone chimney built in the 1950s, and you get spalling brick, crumbling mortar, and a crown that looks like a gravel pit. Masonry repair means resetting the crown, repointing the mortar joints, and replacing brick or stone that has lost its structural face.
In Devon, this is the single most common repair we quote. The cost for a standard crown rebuild and repointing job runs $800 to $1,400, depending on chimney height and how much brick needs replacement. A full rebuild from the roofline up runs $2,500 to $5,000. If the damage has not reached the firebox, you are looking at the lower end.
Crown and Flashing Work
A cracked crown lets water run straight down the flue. A loose flashing seam lets water run down the outside of the chimney and into the chase. We see both on Devon homes with aging stone-to-roof intersections. The fix is a new concrete or mortar crown with a proper drip edge, plus flashing reset and sealed with a high-quality polyurethane sealant. Most crown and flashing jobs on Devon chimneys run $650 to $1,100.
Smoke Chamber Repair
Water that sits in the smoke chamber soaks the firebrick and eventually spalls it, leaving rough, jagged surfaces that trap creosote. That is a fire waiting for a spark. We repair smoke chambers with HeatShield, a spray-on ceramic sealant that restores a smooth, fire-rated surface. Smoke chamber work typically adds $900 to $1,800, and we include camera photos so you can see the before and after yourself.
Chimney Cap Installation in Devon
Chimney Cap Installation in Devon is the repair we recommend more than any other, because a good stainless steel cap stops the water problem before it becomes a masonry problem. A cap keeps rain, snow, and debris out of the flue. It also keeps birds, squirrels, and raccoons from nesting in your chimney. In Devon’s mature tree cover, animals in the flue are a real issue, and a dented or missing cap is almost always how they got in.
A standard stainless steel cap, installed, runs $350 to $650 in Devon. That includes measuring the flue, mounting the cap, and sealing the attachment points. If you need a custom cap for an older, irregular flue opening on a stone chimney, budget $600 to $900. We install caps from Olympia Chimney and Famco, both of which hold up to Pennsylvania winters far better than the big-box galvanized options.
Cap Sizing and Material
The cap must fit the flue tile, not the chase. A cap that is too small restricts draft; one that is too large catches wind and rattles. Our techs measure the flue opening on site and order or carry the right size. Stainless steel is the only material we recommend for Devon’s wet freeze-thaw climate. Galvanized steel rusts in three to five years. Stainless lasts twenty.
When a Cap Is Part of a Bigger Repair
If water has been coming in for years, the cap is often one piece of a larger job. We will not install a cap and walk away while your crown is crumbling. The written estimate covers the full scope. In Devon, we commonly quote cap installation alongside crown repair and flashing work as a single project, typically $1,000 to $1,700 all in.
Trusted Brands We Service in Devon
We work with chimney products that carry their own reputations, so you can verify quality independently. On Devon chimneys, we commonly install Olympia Chimney caps, Famco dampers and caps, and DuraFlex stainless steel liners. We do not push one brand because of margin. We specify the material that fits the job, and we stock common parts for Devon’s older flue sizes, which means faster turnaround. If your chimney needs a part we do not have on the truck, we order it and schedule the repair, still with a written price before any work begins. Hank Delano runs the same brands on his own chimney.
Common Chimney Repair Problems We See in Devon Homes
- Freeze-thaw crown and flashing damage. Devon’s winters cycle between snow, rain, and deep cold, which repeatedly freezes and thaws the water sitting on your chimney crown. Cracks open, flashing seams separate, and water gets behind the masonry. This is the starting point for most of the repair work we quote in Devon’s stone-and-stucco housing stock.
- Spalled firebox brick from years of slow water entry. A chimney can look fine from the outside while the firebox and smoke chamber are quietly falling apart inside. We have pulled out firebox brick in Devon homes that crumbled in our hands. Camera inspection shows the damage before you light another fire.
- Third-degree creosote glaze. Devon’s older homes often burn wood through the winter, and a standard brush sweep cannot remove glazed creosote. It is a hard, tar-like coating that builds up inside the flue over years of skipped inspections. Removing it requires chemical treatments or rotary tools, and it is a fire hazard until it is gone.
- Draft problems from an oversized flue or blocked smoke chamber. Some Devon chimneys were built with flues too large for today’s efficient fireplaces, which cools the exhaust and weakens the draft. The homeowner feels cold air and assumes the chimney is just “cold.” Often it is a repair issue: a flue liner sizing problem or a smoke chamber that needs rebuilding.

FAQs About Chimney Repair in Devon
Every year, according to NFPA 211, the national fire safety standard for chimneys and vents. In Devon, we recommend a Chimney Inspection - Devon at Level 2 whenever you buy a new home, after any chimney fire, and before switching fuel types, such as from wood to gas. A Level 2 inspection includes everything in a Level 1 sweep plus camera work inside the flue. Given Devon’s freeze-thaw cycles, annual camera inspection is the only way to catch crown cracks and smoke chamber damage before they spread. Call (830) 251-4560 to schedule one.
First-degree creosote is a light, flaky soot that a standard brush removes easily. Third-degree creosote is a hard, glazed, tar-like coating that a brush cannot remove. It forms when wood burns cool and the smoke condenses inside the flue. In Devon, we find third-degree creosote most often in chimneys that have skipped several years of sweeps. It raises the risk of a chimney fire and requires chemical treatment or rotary removal before any other repair can be assessed. A camera inspection tells you which degree you have. Call (830) 251-4560 for an inspection and a straight answer.
Yes. The Garrison Standard means you get a written price before any work starts, and that number does not change. For most repairs, we can give you a price range over the phone based on what you describe and photos you send. The on-site written estimate is the final number, and you approve it before we pick up a tool. No surprises, no price moved at the door. Call (830) 251-4560 for a phone quote.
It depends on how deep the cracks run and whether water is already reaching the firebox. Small hairline cracks can sometimes wait a few months. If you can see missing chunks of mortar or brick, or if you smell a musty odor near the damper after rain, water is already inside and should be addressed before another freeze-thaw cycle. A crown repair in Devon typically runs $800 to $1,200, and waiting usually adds smoke chamber or firebox work to the bill. Call (830) 251-4560 for an inspection and a written price.
Yes. We measure the flue opening, not the stone chase, and install a stainless steel cap sized to that opening. Old stone chimneys often have irregular flue dimensions, so we carry a range of sizes and order custom when needed. A standard cap install on a Devon stone chimney runs $350 to $650. If water has already damaged the crown, we quote the cap and the crown repair together so the whole system is done correctly. Call (830) 251-4560 for a written quote.
