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 Landover
A chimney cap and crown repair in Landover typically runs $340-$890 depending on whether you’re replacing a rusted single-flue cap or rebuilding a spalled crown on a 1960s brick ranch. Most jobs we book in Prince George’s County are completed in a single visit, with our crews dispatching from the Washington, DC office and carrying the common cap sizes and crown coating materials needed for Landover’s post-war housing stock.
We’ve been answering calls with a live person, 24 hours a day, 7 days a week, for over 42 years. That matters in Landover, where chimneys on Brightseat Road and the older ranch pockets off Landover Road routinely go decades between servicings. When you finally call, you don’t want a voicemail. You want someone who knows the difference between a Gelco multi-flue cap and a builder-grade galvanized unit that’ll rust through in three seasons. Our Chimney Cap & Crown team handles everything from custom stainless caps for wood-stove flues to full crown rebuilds on townhome rows with shared party-wall chases. Call (301) 479-9806 for a free estimate.
Why Hearthstone Chimney Co. Is Landover’s Preferred Chimney Cap & Crown Company
Landover homeowners tend to stay put. The 1950s-70s brick ranches and the 1970s-80s townhome rows off Annapolis Road and Landover Road have seen families live in them for twenty, thirty, forty years. We’re built for that customer. Over 42 years in the DC metro, we’ve earned a strong local reputation by documenting every inspection with photos and a plain-English verdict, then backing the work with our 90-Day Done Right Promise in writing. No arguing. If it’s not right, we come back.
Our technicians are background-checked, uniformed, and carry professional-grade materials from HeatShield, Gelco, and Famco on every truck. Most cap and crown jobs in Landover finish in one visit because we stock the sizes that fit the 8″×12″ and 13″×13″ flue openings common in local post-war construction. No-hassle upfront pricing means the number on the estimate is the number on the invoice. And a live person answers every call, every hour, every day. We’ve been burned by contractors too. We don’t operate that way.
Our Chimney Cap & Crown Services in Landover
Custom Cap Fabrication & Installation
Landover’s wood-stove households, especially the ranch homes near Brightseat Road and the older properties backing up to the Beltway, need more than a box-store cap. Standard galvanized units rust through in two to three years here, thanks to our humid summers and the freeze-thaw cycle across twenty-plus below-freezing nights each winter. We fabricate custom stainless and copper caps measured to your flue and your roofline, with proper spark arrestors and animal screening. A custom Famco multi-flue cap we installed last winter on a 1962 ranch off Landover Road still looks new. The owner burns four to five cords a season. Her cap hasn’t budged.

Multi-Flue Cap Systems
Landover’s 1970s-80s brick-and-frame townhome rows present a problem no neighboring jurisdiction matches in concentration: shared party-wall flue chases. One missing or rusted-through cap on a single unit lets water, nesting debris, and vermin migrate across the whole row’s shared masonry. We’ve opened flues in the townhome clusters near Landover Mall where a neighbor’s failed cap had packed debris into three adjoining flues. Our multi-flue cap systems cover multiple flue openings from a single anchored base, protecting the entire chase. We coordinate with adjoining owners when possible, and we document shared-masonry damage with our Level 2 camera so you see what we see.

Crown Repair & Rebuilding
The crown is the concrete slab sealing your chimney top. On Landover’s 1950s-60s ranches, crowns were often poured thin, with weak mortar mix, and fifty years of freeze-thaw has spalled them to gravel. Summer humidity grows moss and organic growth that accelerates cracking. We don’t slap sealant on a crumbling crown and call it done. We cut back to sound concrete, rebuild with proper slope and drip edge, then coat with Gelco CrownCoat or HeatShield for a waterproof finish. A crown repair in Landover typically runs $450-$780. A full rebuild on a large ranch chimney can reach $1,200-$1,600.

Crown Coating & Waterproofing
Not every cracked crown needs rebuilding. If the concrete body is sound but the surface is weather-checked, we prep and coat with professional-grade elastomeric sealers. This is common on 1970s townhome crowns that haven’t yet lost structural integrity. Crown coating in Landover runs $280-$520. We include a camera inspection of the flue interior before we seal anything, because coating a crown while the liner below is compromised is throwing good money after bad. Photos you can see, a plain-English verdict. That’s how we work.

Trusted Brands We Service in Landover
We stock caps, crowns, and repair materials from the brands that professional sweeps actually trust: Gelco for stainless multi-flue caps and crown coatings, Famco for custom-fabricated single-flue and multi-flue units in stainless and copper, and HeatShield for crown repair and resurfacing systems. These aren’t builder-grade substitutes from a hardware store. A Famco stainless cap carries a lifetime warranty against rust-through. The galvanized cap it replaced probably cost $45 and lasted three winters. We keep common Landover sizes on our trucks, so most jobs don’t wait on parts. Fast turnaround matters when you’ve got water coming down the flue every rainstorm.
Common Chimney Cap & Crown Problems We See in Landover Homes
- Missing caps on 1950s-60s brick ranches. Original caps were often galvanized steel or aluminum, and sixty years of DC-area humidity has rusted them to lace. Rain pours straight into the flue, soaking clay tile liners that were already past their reliable service life. We regularly find nests and compacted organic debris three to four feet down the flue on Brightseat Road ranches.
- Moss-covered, cracked crowns accelerating water intrusion. Our humid subtropical summers grow thick moss on chimney crowns, especially where tree canopy shades the roof. The moss holds moisture against the concrete, freeze-thaw opens hairline cracks into quarter-inch gaps, and water follows the cracks straight to the flue liner. By the time a homeowner notices a leak, the liner is often spalling.
- Party-wall chase damage in 1970s-80s townhome rows. One unit’s cracked crown or failed flashing pushes moisture and smoke into adjoining flues through shared masonry. We’ve been called for a cap replacement on one address and found the neighboring flue packed with debris from a missing cap two doors down. The scope changes. We photograph everything and explain it plainly.
- Freeze-thaw spalling on soft 1950s-60s brick. Twenty-plus below-freezing nights each winter fracture mortar joints and spall the soft brick common in Landover’s post-war construction. A cap anchored to a deteriorating crown pulls loose within a season or two. We won’t install a new cap on a crown that won’t hold it. Done right, and we stand behind it.

We price upfront after inspection, not after we’ve started work. The number on the estimate is the number on the invoice.

FAQs - Chimney Cap & Crown in Landover
A new cap and crown alone won’t eliminate a sulfurous odor if your flue still carries oil-combustion residue from a prior boiler conversion. Many Landover ranches originally ran oil and were later converted to gas without relining the oversized flue. The sticky, sulfurous coating doesn’t burn off with gas appliances, and the oversized diameter causes condensation that traps odor. We probe for oil-residue odor and flue sizing mismatch before signing off on any cap job. If the liner is compromised, we’ll show you camera evidence and recommend relining before capping. Call (301) 479-9806 and we’ll inspect it properly.
Yes, it can. Landover’s 1970s-80s brick-and-frame townhome rows share party-wall flue chases, so a missing or rusted cap on one unit lets water, nesting debris, and vermin migrate across shared masonry into adjoining flues. We’ve documented debris from a neighbor’s failed cap blocking a flue two units away. We recommend coordinating cap inspections across adjoining units when possible, and we always camera-inspect the full chase length on townhome jobs. If shared damage exists, you’ll see it in the photos before any work proceeds. Call (301) 479-9806 to schedule.
Twice yearly, minimum, if you’re burning four or more cords a season as primary heat. We pulled up to a 1962 brick ranch off Brightseat Road where the owner heats primarily with a wood stove and had gone three seasons between sweeps. The firebox and smoke chamber were loaded with third-degree creosote that a brush alone wouldn’t touch. Our tech confirmed the original clay tile flue liner was oversized for the home’s gas conversion, found the chimney cap missing and a bird nest jammed at the flue throat, and installed a custom Famco stainless multi-flue cap after running a Level 2 inspection and documenting the spalling crown. We patched and coated the crown with Gelco, added a new damper assembly, and set the homeowner on a twice-yearly sweep schedule to match her burn volume. Heavy creosote loading is a chimney fire risk. Don’t guess at the interval. Call (301) 479-9806 and we’ll set a schedule that matches your actual burn.
We won’t, and any sweep who offers to is cutting a corner you’ll pay for later. Freeze-thaw cycling across Landover’s twenty-plus below-freezing nights each winter spalls the soft 1950s-60s brick around the crown edge and fractures mortar joints. A cap anchored to a deteriorating crown pulls loose within a season or two, taking flashing and brick with it. We inspect the crown with every cap job, photograph the condition, and explain your options. Sometimes a coating suffices. Sometimes we need to rebuild before the cap goes on. Either way, you see the evidence and get a fixed price before we start. Call (301) 479-9806 for an honest assessment.
Expect layers of compacted creosote, possible collapsed clay tile sections, missing or rusted caps that have allowed nesting and moisture intrusion for years, and crowns cracked open by moss and freeze-thaw. Landover’s residential core was built out almost entirely in the 1950s-1970s, and many homes experienced high ownership turnover during demographic shifts of the 1970s-80s, meaning chimneys routinely go decades between servicings. We approach these jobs methodically: Level 2 camera inspection first, photos you can see, a plain-English verdict on what needs immediate attention versus what can be monitored. Nothing is recommended without camera evidence you can see for yourself. We’ll also tell you plainly when work can safely wait. Call (301) 479-9806 to schedule - estimates are free.
