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.
Fast, Reliable Chimney Cap & Crown Across Woodlawn
Chimney cap and crown repair in Woodlawn typically runs $280-$950 depending on whether we’re coating cracks, rebuilding the crown, or replacing a corroded cap, and most jobs are completed in a single visit with the work backed by our 90-Day Done Right Promise in writing. If you’re seeing rust stains on the brick, water in the firebox, or pieces of concrete on the roof, the crown or cap has already failed and water is getting into the flue.
We’ve been answering calls with a live person 24 hours a day for over 42 years, and our crews serve Woodlawn from our Baltimore office. We know the post-WWII ranchers off Security Boulevard, the Cape Cods near Woodlawn High School, and the split-levels along Rolling Road - homes built with chimneys sized for oil-fired boilers, then converted to gas, now dealing with crowns and caps that have taken fifty-plus years of Baltimore County freeze-thaw cycles. Call (410) 305-7884 for a free estimate. We’ll be there when we say.
Why Hearthstone Chimney Co. Is Woodlawn’s Preferred Chimney Cap & Crown Company
Woodlawn homeowners call us because we document what we find.

Our Chimney Cap & Crown team carries professional-grade materials from Olympia Chimney, Famco, and Copperfield, so we don’t leave to “go get parts” while your chimney stays open to the weather.
Our technicians are background-checked, uniformed, and complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.

Dispatch and scheduling are coordinated from our Baltimore office, but crews are in Woodlawn regularly. We understand the local failure patterns - the oil-to-gas conversion legacy, the flat crowns with no drip edge, the galvanized caps that rust through at the seams. This isn’t generic chimney knowledge. It’s Woodlawn-specific experience.
Our Chimney Cap & Crown Services in Woodlawn
Cap Installation
New cap installation on a Woodlawn chimney runs $280-$520 for a standard stainless single-flue cap, or $450-$780 for a multi-flue cap that covers the entire crown. We size caps to overhang the crown edge and include a drip edge that sheds water away from the brick - a detail missing on most original tract-build chimneys. For homes along Security Boulevard and the surrounding 1950s neighborhoods, we often recommend stainless over galvanized. The salt air from the Chesapeake, combined with acidic gas exhaust condensing in undersized flues, eats galvanized caps from both sides. Stainless lasts.

Cap Replacement
Cap replacement is our most common Woodlawn call. Original galvanized caps on the area’s 1948-1970 ranchers corrode at the seams and fastener points well before the crown itself fails. Homeowners notice rust streaks down the brick, or the cap blows off in a storm because the fasteners have rotted through. We remove the failed cap, inspect the crown and flue beneath it, and install a replacement that fits properly. A square deal: no surprises on the bill. If the crown is damaged underneath, we’ll show you the photo and explain whether coating or rebuilding makes sense before we proceed.

Crown Repair
Crown repair in Woodlawn typically means rebuilding a concrete crown that was cast flat in the 1950s or 1960s with no overhang and no drip edge. These crowns crack at the bond line, let water into the chase, and wash mortar out through 30-40 freeze-thaw cycles every Baltimore County winter. A full crown rebuild runs $650-$950. We form a new crown with proper slope, a 2-inch overhang past the brick face, and a drip edge that prevents water from running back underneath. Done right - and we stand behind it.

Crown Coating
Crown coating is the right choice when the crown has hairline cracks and minor surface deterioration but the concrete body is still sound. In Woodlawn, we see this on chimneys where the cap was replaced early enough to protect the crown from direct rain exposure. Coating runs $280-$450 and buys years of additional service. We clean the crown, fill cracks, and apply a flexible, waterproof membrane that moves with the concrete through freeze-thaw cycles. Not every crown qualifies. We’ll tell you honestly if coating is a Band-Aid on a crown that needs rebuilding.

Common Chimney Cap & Crown Problems We See in Woodlawn Homes
- Galvanized caps corroding at the seams. Original caps on Woodlawn’s 1948-1970 ranchers rust through where the seams meet and where fasteners penetrate the metal. The salt air and acidic gas exhaust attack from both sides. By the time you see rust stains on the brick, water has already been entering the flue for one or two seasons.
- Flat crowns with no overhang or drip edge. Tract builders poured these crowns level with the brick or with a slight inward slope. Rain sits on them, freezes, expands, and opens cracks that funnel water straight into the chimney structure. Spring rain combined with winter moisture infiltration through open crown joints is a leading driver of interior tile liner collapse in Woodlawn’s older stock.
- Efflorescence and tile delamination from gas exhaust condensation. High-efficiency gas furnaces exhaust cooler, moisture-laden flue gases into chimneys sized for 500-degree oil burners. The condensation drives white efflorescence on the exterior brick and causes clay tile flue liners to delaminate. Homeowners blame the crown or cap for moisture, but the real source is the flue mismatch. We identify this with our Level-2 camera inspection and explain it with photos.
- Flashing separation as mortar spalls. Step and counter flashing on Woodlawn’s single-wythe masonry chimneys pulls away from the brick as freeze-thaw cycles spall the mortar surface. This opens a second water path beside the crown, and water enters behind the flashing even when the crown itself looks intact.

FAQs - Chimney Cap & Crown in Woodlawn
Your cap is probably galvanized steel, the standard on 1950s-1960s Woodlawn tract homes, and the combination of Baltimore County humidity, salt air from the Chesapeake, and acidic gas exhaust condensing in your flue corrodes it from both the outside and inside. We replace failed galvanized caps with stainless steel units from Famco or Copperfield that last decades instead of years. Call (410) 305-7884 for an exact quote - estimates are free.
Hairline cracks in a crown that still has proper slope, overhang, and structural soundness can be coated with a flexible waterproof membrane for $280-$450. If the crown is flat, severely cracked, or spalling at the edges, coating is a temporary fix and rebuilding is the honest recommendation. We show you the photo and explain which category yours falls into before you decide. Call (410) 305-7884 for an exact quote - estimates are free.
Multi-flue caps cover the entire crown and protect multiple flues or a large chase - common on Woodlawn’s bigger ranchers with separate furnace and fireplace flues. Custom caps are sized for unusual dimensions or specified in copper for appearance. Most Woodlawn homes do fine with a properly sized stainless single-flue or multi-flue cap from our standard inventory. We measure on site and recommend what fits your chimney, not what costs more. Call (410) 305-7884 for an exact quote - estimates are free.
We perform a Level-2 inspection, which includes a camera run through the flue and photos of the crown, cap, and interior surfaces. On Woodlawn’s 1950s-1970s chimneys, we’re looking specifically for the oil-to-gas conversion damage pattern: condensation damage, tile delamination, and crown deterioration from the inside out. You get the photos and a plain-English verdict. Call (410) 305-7884 for an exact quote - estimates are free.
Liner damage from gas exhaust condensation is the dominant hazard we find, not creosote buildup. Because Woodlawn’s post-WWII chimneys were sized for high-temp oil burners and later swapped to gas without relining, the moisture-laden gas exhaust condenses against 1950s clay tile and rots crowns and caps from the inside out. This oil-to-gas conversion legacy follows the Security Boulevard corridor’s tract houses and is far less common in newer suburbs built straight to gas. We check liner integrity on every inspection and explain what we find. Call (410) 305-7884 for an exact quote - estimates are free.
On a brick rancher off Security Boulevard, our tech found a galvanized cap that had corroded through at the seams and a crown with open shrinkage cracks feeding water straight into a delaminating 1950s tile flue liner. We set a new stainless multi-flue cap, rebuilt the crown with an overhang and drip edge, and coated it - then HeatShield-lined the flue to close the oil-to-gas mismatch. The homeowner’s shoulder-season downdraft and efflorescence complaints both cleared.
