Broken chimney cap? We fix it fast! Keep water, animals, and leaves out of your home. Serving DC, Maryland & Virginia homes.


Why does your fireplace smell musty after a storm? A damaged chimney cap could be letting rain soak into your bricks. Heavy rains and windy days push old caps to their limit. Animals like raccoons or birds often rip through weak covers, too. That’s where we step in. Delta Air Duct DMV specializes in chimney cap replacement across Washington, DC. We use thick steel or copper caps custom-cut for your chimney’s exact size. Our team seals edges tight so water can’t seep in, preventing rot.
A strong cap blocks sparks from landing on your roof during winter fires. It also keeps leaves and debris from clogging your flue, which prevents dangerous smoke backups. For DMV homeowners, this means fewer repair bills and safer winters. We know local weather patterns, so we install caps that handle thunderstorms, humidity, and ice.

We start by hauling heavy-gauge steel or copper up your roof, no flimsy aluminum. Our crew measures your flue’s exact width and height using laser tools, because guessing wastes your money. Next, we scrape off old tar or cement until the chimney crown shines clean. Any cracks get filled with hydraulic mortar that hardens fast.
We drill pilot holes into the brick, not the mortar, so your structure stays sound. Stainless steel screws lock everything down with rubber washers that won’t crack in freezing winters. Finally, we smear high-temp silicone around the base to seal out rain and squirrels.
We test every cap by hosing it at angles and checking for drips inside your fireplace. And since DC rowhouses have tight roofs, we use compact lifts instead of bulky ladders.

Wondering how much a chimney cap replacement costs? It mostly depends on your flue size and chosen material. Small steel caps cost less than wide copper ones, since copper lasts three times longer. Then there’s roof pitch. Steeper roofs need extra safety gear and time, which adds to labor. If your chimney crown has cracks, we patch it first so the cap seals tight. Old mounting hardware removal also takes time and extra labor. We add all this in one upfront quote so you know exactly what you’re paying for.
DMV weather demands thicker-gauge steel than other areas to handle ice storms. We use commercial-grade sealants rated for freeze-thaw cycles. Cheap caulk fails fast. Plus, custom fabrication for odd-sized flues adds precision cutting time. But you get durable protection that handles heavy storms without rusting or rattling loose after one season.
