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.

AfterFast, Reliable Chimney Cap & Crown Across Clinton
A chimney cap and crown replacement in Clinton typically runs $450-$1,800 depending on the flue configuration, and most jobs are completed in a single visit. We schedule Clinton work within 3 to 5 business days during fall and early winter, which is when Prince George’s County homeowners start lighting fires again. If you’re seeing water stains on the ceiling near the chimney, cracked mortar on the crown, or rust bleeding down the brick, call (980) 580-8641 and we’ll tell you exactly what we’re looking at before anyone books an appointment.
Clinton’s housing stock has a specific profile: brick colonials and split-levels built between 1960 and 1985 for federal workers and military families tied to Joint Base Andrews. Those chimneys are now hitting the age where cap and crown failures stop being a maintenance item and start being a structural one. We know the subdivisions off Old Branch Avenue, Woodyard Road, and Brandywine Road, and we know what those chimneys look like inside because we’ve put cameras down hundreds of them.
Why Emberly Chimney Cleaners Is Clinton’s Preferred Chimney Cap & Crown Company
We don’t ask you to trust us. We show you the flue on camera, hand you a written price before any work starts, and leave you with a photo record of what was done. That’s the Haven Standard, and it’s been our operating rule since 2009 when Corrine Halstead founded the company. Clause 4 of the Haven Standard requires a documented photo record on every job, and that includes cap and crown work in Clinton, no matter how small the repair looks from the ground.
Our technicians arrive in uniform, background-checked, and with a named tech assigned to your appointment. You get a text when we’re on the way. When the job’s done, you get photos of the new cap, the rebuilt crown, and the flue interior. Clinton homeowners tell us the same thing: the camera footage is what convinced them, not the sales pitch. If you have a written estimate from another company, bring it to us. We’ll give you a free second opinion, and we’ll match apples to apples on scope.
Our Chimney Cap & Crown Services in Clinton
Cap Installation
Most 1970s Clinton colonials were built with clay tile flues sized for open fireplaces, and many never had caps installed at all. That’s an open pipe to the sky: rain, squirrels, birds, leaves. A properly sized stainless or copper cap stops all of it. We measure the exact flue dimensions on site and quote you a cap from Olympia Chimney or Famco, not a one-size-fits-most piece from a big-box shelf.
Cap Replacement
If your existing cap is rusted through at the base or the screen is torn, water is already getting in. We see this constantly on Clinton homes where the original cap was cheap galvanized steel, now corroded on the top before the flakes rusted off and fell into the firebox. This page’s most common replacement call is a rusted multi-flue cap on older split-levels. We’ll show you the old cap next to the new one before we bolt anything down.
Crown Repair
The mortar crown is the chimney’s roof, and on Clinton’s freeze-thaw cycle it’s the first thing to go. Hairline cracks take in water; that water freezes, expanding and popping more mortar loose. Left alone, it spalls the brick underneath and eventually the cap area crumbles. We repair crowns with a reinforced mortar mix, or in severe cases rebuild the crown and seal it with a Gelco crown coating to buy you decades.
Crown Coating
A crown coating isn’t paint. It’s a flexible, waterproof membrane that bridges the existing mortar crown so water can’t get into micro-cracks. For Clinton’s older chimneys where the crown is still sound but showing hairline fracture lines, a coating is a few hundred dollars instead of a full rebuild, and we can tell you honestly which one your chimney needs. We’ll never recommend a rebuild when a coating will hold.

BeforeAfterTrusted Brands We Service in Clinton
We stock and install caps and crown materials from Olympia Chimney, Famco, and Copperfield. Those are the names that hold up to Prince George’s County humidity and freeze cycles. Because we buy through Haven’s network, our Clinton customers get honest pricing on materials, not the marked-up retail price you’d see buying direct. If your existing cap is a brand we don’t carry, we’ll tell you that too, and source the right match rather than adapting something that almost fits.
Common Chimney Cap & Crown Problems We See in Clinton Homes
- Freeze-thaw crown cracking on 1960s split-levels. Clinton’s inland humid subtropical climate means winter nights below freezing followed by daytime thaws, every week, for months. Water seeps into the mortar crown, freezes, and expands. By year 40 or 50, the crown looks like a cracked sidewalk. We repair this daily across Clinton.
- Rusted prefabricated chase covers on newer factory-built fireplaces. Homes built after about 1990 in Clinton often have factory-built chimneys with metal chase covers. Summer humidity rusts the seams from the inside. Rain runs down the flue, and by the time you see water in the firebox, the damper is already corroding. We inspect these on every cap and crown visit.
- Missing caps on original clay tile flues. Thousands of Clinton colonial and rancher chimneys never got caps. Rain sits in the flue, mixes with creosote, and becomes an acid that eats the clay tiles from the inside out. Cap installation stops that cycle dead, and it’s the cheapest repair we do relative to the damage it prevents.
- Birds and squirrels nesting in open flues off Old Branch Avenue. The subdivisions along Old Branch Avenue and Woodyard Road have mature trees close to rooftops. Open flues invite nesting. We remove what’s there, show you the camera footage, and cap the flue so it doesn’t happen again.
Pricing for Chimney Cap & Crown in Clinton, MD

FAQs - Chimney Cap & Crown in Clinton
Because the 1970s Clinton building boom used fast, cheap masonry: single-wythe brick, standard clay tile liners, and thin mortar crowns. Those materials hit the end of their service life around year 40 to 50. Clinton’s freeze-thaw winters and humid summers accelerated the failure. If your home was built between 1965 and 1980 and no one has touched the cap or crown since, it needs inspection now, not later. Call (980) 580-8641 and we’ll put a camera on it.
Yes. Factory-built fireplace chases in Clinton fail from the top down: the sheet-metal chase cover rusts at the seams, rain gets in, and the damper corrodes. You won’t see it from the ground, and the fireplace will still light fine right up until it doesn’t. A camera inspection costs less than the chase cover you’ll eventually need if the rust keeps going.
Yes. We measure the flue above the crown and order a cap sized to those exact dimensions. Most original Clinton clay tile flues are standard dimensions, so stock Olympia Chimney and Famco caps fit well. For odd sizes, we custom order. You’ll see the measurements and the cap before installation.
Freeze-thaw spalling. The original mortar crowns on 1960s Clinton split-levels were poured thin, often without proper rebar or expansion joints. Decades of ice expansion crack them, water gets in, and the crown starts shedding chunks. Once the crown spalls, the brick below it follows. We rebuilt one of these on a 1972 split-level off Old Branch Avenue, replacing a corroded multi-flue cap with an Olympia Chimney cap sized to the original clay tile liners. The homeowner’s neighbor had the same failure, so we scheduled both jobs back-to-back. That’s a Clinton pattern, not a one-off.
Rain enters an uncapped or damaged flue, mixes with creosote, and creates an acidic slurry that restricts airflow. Restricted airflow means fires burn cooler and smokier, which produces Class III creosote: hard, glassy, and the most difficult and dangerous type to remove. The fix starts with the cap. If your chimney hasn’t been capped or the existing cap is damaged, call (980) 580-8641 and we’ll show you what the flue looks like on camera before we touch anything.
