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.

Wendell and his crew spent over 29 years working chimneys throughout this part of the county, and Garrison has a particular set of problems we see again and again.

We’ll tell you what’s actually wrong, show you the footage, and walk away from a job that doesn’t need doing.

Our Chimney Repair Services in Garrison
Flashing Repair
Flashing failure is the single most common repair we make on Garrison roofs. The heavy tree canopy holds moisture against the roofline, and the steep pitches on many of these custom colonials put real stress on the metal. When flashing separates or corrodes, water walks straight down into the smoke chamber and firebox. That’s how you get spalling brick and a draft that pulls smoke back into the living room. We replace flashing with Copperfield products when the situation calls for it, and we seal the transition properly, not just caulk over the gap.
Spalling Brick Repair
Spalling is what happens when water gets inside a brick and freezes, popping the face off. Garrison sits at a slightly higher elevation than the city, so the freeze-thaw cycling is a little more aggressive. We see it most often at the roofline and on exposed chimney crowns. If the damage is caught early, we can cut out and replace individual brick. If it’s advanced, we’ll show you the camera footage and talk honestly about whether a partial rebuild makes more sense.
Chimney Waterproofing
Masonry chimneys are porous. When you combine that with Garrison’s wooded lots and the moisture they hold, you get accelerated mortar deterioration and crown cracking. We apply a vapor-permeable waterproofing treatment after repairs are complete. It keeps water out while letting the masonry breathe. This is a job that prevents five other jobs, and we’ll tell you plainly if your chimney doesn’t need it yet.
Chimney Rebuilding
Some Garrison chimneys are beyond patching. If the mortar has turned to sand and the bricks are spalling from multiple faces, rebuilding the upper section is usually cheaper in the long run than chasing repairs every other year. We rebuild from the roofline up or from the crown down, matching brick and mortar as closely as the original construction allows. We’ll show you exactly what we’re removing before we remove it. Tuckpointing is part of this work too, when the lower masonry is sound but the joints are shot. Expect tuckpointing in Garrison to run $8-$15 per square foot of wall face, depending on access and joint depth.

DuraFlex liners handle the gas and oil appliance venting situations we find in so many Garrison homes that converted decades ago. Gelco and Olympia Chimney supply the caps and crowns that stand up to our weather. Because we stock common parts locally, turnaround for Garrison jobs is faster than waiting on a national supplier. We’ll tell you which product we’re using and why, and you’ll see the manufacturer’s name on the quote.
Common Chimney Repair Problems We See in Garrison Homes
- Dead oil-furnace flues left open and unlined. When a Garrison home converted from oil to gas, the old flue was often simply abandoned. Open, uncapped, and unlined for decades, it becomes a debris trap. We regularly pull out animal nesting material and rotted leaves from flues homeowners never knew were there.
- Clay tile liners cracked by freeze-thaw cycling. Mid-century chimneys in Garrison were built with clay tile, and clay doesn’t flex. Decades of freezing and thawing crack the tiles, letting creosote and moisture migrate into the masonry. That’s how small water stains become big rebuilds.
- Flashing failures on heavily canopied roofs. Mature oaks and tulip poplars drop leaves and needles onto the roof, holding water against the flashing line. By the time you see a stain on the ceiling below the fireplace, the flashing has usually been failing for two or three seasons.
- Multiple chimneys, multiple problems. Many Garrison homes have two to four separate flue systems, one for the main fireplace and others serving furnaces, water heaters, or since-abandoned appliances. Homeowners inspect the one they use and never look at the others. The secondary flues are where we find the worst damage.
Pricing for Chimney Repair in Garrison, MD
Here’s what you’re looking at for common repairs in Garrison right now. Flashing repair: $450-$900. Tuckpointing a typical chimney face: $700-$1,800. Spalling brick replacement: $1,200-$3,500 depending on how many faces are involved and how high the damage runs. A full chimney rebuild above the roofline: $2,500-$6,000. Flue resurfacing with HeatShield: $1,800-$4,200, which beats a full liner replacement when the tile structure is mostly sound.

FAQs - Chimney Repair in Garrison
Many Garrison homes built in the 1950s through 1970s originally burned oil for heat, and the furnaces vented through a dedicated masonry flue. When those homes converted to gas, the old flue was often capped off at the basement and simply forgotten. We find these dead flues on a huge share of the houses along Garrison Forest Road and through the Green Spring Valley, open at the top, never lined, and packed with debris. The only way to know if yours is dangerous is a camera inspection. We’ll show you the footage, and if the flue is being used to vent anything at all, we’ll recommend relining it before it fails. Call (443) 332-7798 to schedule a look.
Spalling brick means water has gotten inside the masonry and frozen, fracturing the brick face. In Garrison, with the slight elevation and the extra freeze-thaw cycles, it’s the early warning sign for a flashing failure or a cracked crown. If the damage is limited to a few bricks and the surrounding mortar is still sound, we can cut out and replace individual units. If the spalling wraps the chimney or reaches down into the smoke chamber, we’ll tell you honestly that a partial rebuild is the better use of your money. You’ll see the camera evidence before you spend a dollar.
Yes, at minimum inspect them all. A single Garrison estate home can have three or four separate flue systems, and the ones that get used are the ones that get maintained. The secondary flues serving converted furnaces or abandoned oil appliances are where we consistently find the worst damage: cracked clay tile, missing caps, animal nesting, and creosote glaze that hasn’t been touched in decades. We’ll inspect every flue on the property as part of a single visit. Repair what needs it, and tell you plainly which ones can wait.
Faster than you’d think. The mature oaks and tulip poplars that give Garrison its character also funnel leaf litter onto chimney crowns, and that organic material holds moisture against the masonry for weeks after a rain. Once the crown cracks, water moves into the mortar joints, and the freeze-thaw cycle in our part of the county does the rest. We’ve seen chimneys go from minor crown cracking to significant spalling in three seasons. Waterproofing and crown repair can stop that clock. Call (443) 332-7798 and we’ll give you a straight assessment.
They can be. Chimney swifts are a federally protected migratory bird, and they nest in open chimneys throughout Garrison during the warmer months. If we find an active nest, we can’t legally disturb it, and we’ll schedule the repair for after the birds have left, usually in late summer. The best way to avoid the scheduling problem entirely is a chimney cap. We install caps from Gelco and Olympia, and it’s a one-time fix that keeps birds, raccoons, and half the rain out of your flue. If you’ve heard chirping in the chimney or seen birds dropping down it, call us and we’ll tell you exactly what the timing looks like.
