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.

Our Chimney Cap & Crown Services in Lansdowne
Cap Installation
Most Lansdowne homes either have no cap at all or a galvanized lid that’s rusted through after a decade of Patapsco River valley humidity. We install stainless steel and copper caps sized for your flue, not whatever’s left on the truck. For Cape Cods and bungalows with oversized coal-era flues, that sizing matters more than you’d think. A cap that doesn’t fit right lets rain and birds in while trapping condensation inside. We measure, we show you the photo, and we install it the same afternoon.
Cap Replacement
If you’ve got a cap that’s rusting out every few years, there’s usually a reason beyond cheap metal. In Lansdowne, it’s often acidic condensation from a high-efficiency gas appliance venting into a flue that was built for coal. That acid eats galvanized steel from the inside. We’ll tell you if a standard replacement will hold up or if you need stainless or a custom fit. We carry Gelco and Olympia Chimney caps for the common Lansdowne setups and can order a custom piece when the flue isn’t standard.
Crown Repair
The mortar crown on a 1950s Lansdowne chimney takes a beating. Summer humidity soaks the mortar. Winter freezes it. Repeat that fifty times and the crown cracks, spalls, and lets water pool around the clay tiles. We grind down the loose material, rebuild the crown with a proper slope so water runs off instead of sitting, and check the flue gap while we’re up there. On a brick Cape Cod off Hammonds Ferry Road, our crew pulled a rusted cap to find the crown so far gone the flue gap was completely exposed. That’s not an upsell moment. That’s Chimney Repair in Lansdowne we can show you on camera before we touch anything.
Crown Coating
When the crown structure is still sound but the surface is porous and starting to flake, a Gelco crown coat buys you years without a full rebuild. We grind the surface clean, fill the hairline cracks, and apply the sealant so it flexes with Lansdowne’s freeze-thaw cycles instead of cracking apart. It’s a half-day job for most bungalows and rowhouses in the 21227 zip code, and it costs less than half of a full crown replacement.

Trusted Brands We Service in Lansdowne
We stock and install caps from Gelco, Olympia Chimney, Famco, and Copperfield, and we match the right brand to the chimney in front of us. A Copperfield copper cap looks right on a well-kept brick bungalow on a tree-lined street. A Gelco stainless lid is the workhorse for a rental rowhouse that just needs to keep water out for the next twenty years. Because we serve Lansdowne regularly, we keep common sizes in the truck so most cap jobs don’t need a second visit.
Common Chimney Cap & Crown Problems We See in Lansdowne Homes
- Freeze-thaw spalling from river-valley humidity. Lansdowne sits at the edge of the Patapsco River valley, and that fog and damp air accelerates mortar erosion on the area’s aging brick crowns. Moisture soaks in during humid summers, freezes in winter, and pops the surface loose in chunks.
- Caps installed for coal or oil flues that now sit loose on the opening. The original 1940s-1960s chimneys were built for a different fuel. When the appliance changed but the flue didn’t, the cap never got resized. Rain, squirrels, and birds all find their way in through the gaps.
- Condensation from high-efficiency gas inserts running down unlined clay flues. This is the one you can’t see from the ground. Acidic byproducts from gas combustion condense inside the flue, run down, and eat the crown mortar from below. By the time the crown cracks apart on top, the damage inside is already years along.
- Rust streaks and staining on the crown. If you’re seeing orange-brown stains running from the cap down the brick, that’s a galvanized cap dissolving. On humid days the smell near the chimney can be a dead giveaway. It’s usually not a masonry failure yet, but it’s a cap that needs replacing before the crown underneath starts soaking up the runoff.

FAQs - Chimney Cap & Crown in Lansdowne
Acidic condensation from a modern gas appliance venting into your coal-era clay flue is the usual culprit in Lansdowne. The flue is oversized for the appliance, the exhaust cools too fast inside it, and the resulting acidic water eats galvanized caps from the inside. The fix is a stainless or copper cap sized correctly for the flue, not another cheap galvanized lid. Call (443) 332-7798 and we’ll put a camera up there to confirm before quoting anything.
Yes, and we won’t install a cap on a failing crown. If the crown is cracked or spalled, the cap will sit unstable and water will still pool around the flue tiles underneath it. The crown is the chimney’s roof; the cap is the vent cover. On Lansdowne’s older bungalows, if the tiles are visibly cracked from above, we usually need to repair the crown and evaluate the liner before adding a cap. The camera footage will show you exactly what we mean.
Sometimes, but many Lansdowne coal-era flues are a nonstandard size, and a generic cap either sits too loose or doesn’t cover the full opening. If your home was built before 1960, there’s a decent chance you need a custom or multi-flue cap to seal the opening properly. We’ll measure and show you the fit before we install. That’s the only way to keep rain and animals out while letting the flue breathe the way it should.
That’s usually condensation inside the flue pooling around the crown area, and it’s common in Lansdowne’s foggy river-valley conditions. The acidic byproducts from gas exhaust build up in trapped moisture and seep back through cracks in the crown. It can be either a crown or a cap problem, and the only way to know is to look. We’ll run a camera and show you where the moisture is collecting before recommending anything.
It does. The Patapsco River valley holds humidity against the mortar through the summer, and when winter freezes arrive, that absorbed water expands and spalls the surface. Crowns in Lansdowne fail faster than identical crowns in drier inland towns. A crown coat with a flexible sealant like Gelco helps, and proper annual attention extends the life. Call (443) 332-7798 for a free estimate, and we’ll give you an honest read on how much time your crown still has.
