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 Severn
A chimney cap replacement or crown repair in Severn typically costs $350-$850 for a standard galvanized cap swap and $600-$1,400 for a full crown rebuild with a waterproof coating, with most work done in a single visit. The real question in Severn isn’t whether you can find someone to do the job. It’s whether the materials they use will survive the salt air off the Chesapeake and the freeze-thaw cycles that punish masonry all winter. Our Chimney Cap & Crown team has been fixing both across Severn long enough to know what fails first, what can wait, and what needs to be torn off before the next rain. Call (443) 332-7798 for a straight answer and a free estimate.
Wendell Pike started Top Hat Chimney in 1999, and he’s the one who backs every cap and crown job with our 90-Day Done Right Promise, in writing. If it’s not right, one call brings him back. No runaround, no call center, no stranger at your door. Just the same person who quoted the job, doing the job.
Why Top Hat Chimney Is Severn’s Preferred Chimney Cap & Crown Company
We’re not a franchise that rotated into the Fort Meade corridor last spring. Wendell has been running Top Hat Chimney since 1999, and he picks up the phone himself more often than not. That matters in Severn, where the housing stock has a very specific set of chimney problems, and a tech who doesn’t know the difference between a Heatilator prefab and a true masonry chimney is going to give you bad advice. Wendell and his crew know both.
Homeowners across Severn have dealt with enough national outfits that quote one price on the phone and a different one at the door. That’s not how we work. You get a price before a single tool comes off the truck, and that’s the number on your invoice. If you already have a written estimate from another company, bring it to us and we’ll give you a free second opinion with no obligation. That’s a standing offer, not a marketing gimmick.
We also know how to move in this area. Severn is a short run for us, and we schedule real arrival windows, not “sometime between 8 and 6.” If something slips, you get a call before the window closes, not after. And when you call Top Hat, a live person answers, 24/7. Not a voicemail box. Not a call center in another state. We’re Chimney Cap & Crown in Severn, and we answer like it.
Our Chimney Cap & Crown Services in Severn
Cap Installation
A cap isn’t decoration. It’s the roof over your flue, and in Severn it’s the first line of defense against rain, squirrels, and the starlings that nest near the Severn Run marsh. We install caps sized to your specific flue, not a one-size-fits-all piece from a box store. For most Severn homes we recommend stainless steel over galvanized, and we’ll explain exactly why when we look at your chimney. A standard stainless cap installation runs $350-$650 depending on flue size and access.
Cap Replacement
If your prefab fireplace has a galvanized cap that’s been up there since the Clinton administration, it’s probably rusted through at the mounting tabs. That’s the failure we see most often in Severn, and it lets water drip straight down onto the smoke shelf where you can’t see it until the damage is done. We replace corroded caps with stainless steel units from Olympia Chimney or Famco, and we treat any surface rust on the flue before the new cap goes on. Replacement runs $400-$750 including removal and disposal of the old cap.
Crown Repair
On a masonry chimney, the crown is the concrete slab that sheds water away from the flue. Severn’s freeze-thaw cycles make crowns spall: water seeps into hairline cracks, freezes, expands, and pops small chunks of concrete loose. Left alone, that water works its way into the firebox and smoke chamber. We repair crowns by removing loose material, rebuilding the slope so water sheds properly, and sealing with a breathable crown coating. Crown repair in Severn typically runs $600-$1,200 depending on crown size and damage.
Crown Coating
Sometimes the crown is structurally sound but the surface is porous enough to absorb water. In that case we don’t need to rebuild anything. We apply a flexible crown coating, often from Gelco, that fills micro-cracks and moves with the chimney through temperature swings. It’s a lower-cost fix that can add years to a crown before a full rebuild is necessary. Coating alone runs $300-$600 and is a good option when our camera inspection shows the crown’s structure is still intact.

Trusted Brands We Service in Severn
We work with brands built for coastal Maryland conditions, not whatever’s cheapest on the shelf. For Severn’s prefab-heavy housing stock, we stock and install caps from Olympia Chimney and Famco, both of which offer stainless steel options we’ve watched survive the bay’s salt air year after year. When a firebox needs surface treatment or a liner needs repair, we use HeatShield. And when someone has a competing estimate with a brand we don’t recognize, we’ll tell you straight whether it’s worth the difference or not. We’d rather lose a job than install a cap that’s going to rust out in five years and send the next owner back to square one.
Common Chimney Cap & Crown Problems We See in Severn Homes
- Rusted-through galvanized caps on prefab fireplaces. Severn’s proximity to the Chesapeake means salt air works on galvanized steel faster than inland. Most galvanized caps here are done within 5-8 years, which is why we tell homeowners to treat stainless as the default, not an upgrade.
- Spalled crowns on masonry chimneys. High humidity softens the concrete surface, then winter freeze-thaw cycles pop pieces loose. We see this constantly on Severn’s 1970s and 1980s tract homes where the original crown was poured thin and never sealed.
- Loose or corroded flashing where the chimney meets the roof. On Severn’s older subdivisions like Shipley’s Choice and Severn Forest, the flashing was installed decades ago and has been expanding and contracting through hundreds of temperature swings. Water follows the gaps and rots the roof decking before anyone sees a stain on the ceiling.
- Uncapped or under-capped flues on rental turnovers. Because so many Severn rentals change hands with military PCS moves, a lot of fireplaces go multiple occupancy cycles without anyone looking at the cap or crown. By the time we get called, the flue has been open to rain and animals for years.

FAQs - Chimney Cap & Crown in Severn
In Severn, a galvanized steel cap should be expected to last 5-8 years before corrosion compromises it, while a stainless steel cap can last 15-20 years or more. The salt air off the Chesapeake accelerates corrosion, so if your cap is galvanized and older than five years, it’s worth having it looked at during your annual sweep. Call (443) 332-7798 to schedule an inspection, and we’ll show you exactly what we see.
In most Severn homes with prefab zero-clearance fireplaces, a rusted cap can be replaced without touching the firebox or the rest of the system. We recently replaced a corroded galvanized cap on a Heatilator in Shipley’s Choice. The cap had rusted through at the mounting tabs from years of bay moisture, letting water drip onto the smoke shelf. Our techs removed the old cap, treated the surface rust with HeatShield, and installed an Olympia Chimney stainless steel cap with a custom screen to keep out birds. The fireplace itself was fine. The only time you need a new system is if water has been getting in long enough to rust the firebox or the flue itself, and that’s something our camera inspection will show you directly. Call (443) 332-7798 for a free look.
If a crown was repaired with a standard mortar mix instead of a crown-specific material, it’ll crack again within a few years in Severn’s freeze-thaw climate. Standard mortar isn’t built to flex with temperature swings, and the Chesapeake’s humidity makes the problem worse. We rebuild crowns with materials designed to shed water and move with the chimney, then apply a flexible coating so water can’t get into micro-cracks. If you’ve had a crown repaired more than once, call (443) 332-7798 and we’ll show you what went wrong the first time.
Yes, the landlord is legally responsible for maintaining the chimney and fireplace in safe working condition. Maryland law requires rental properties to be fit for habitation, and that includes properly functioning heating and ventilation systems. Anne Arundel County’s rental inspection process does not routinely flag chimney condition, which means the first post-vacancy cleaning often becomes the de facto safety check for the next occupant. If you’re a tenant in this situation, document the problem in writing, and if the landlord still won’t act, contact Anne Arundel County’s housing enforcement office. We can also provide a written report of what we find if you need documentation for a complaint. Call (443) 332-7798 for a free estimate on the inspection.
A properly fitted cap with the right mesh size will keep squirrels, starlings, and other birds out of your flue, and it’s the only sure way to do it. The birds common around the Severn Run marsh are persistent nesters, and a missing or damaged cap is an open invitation. We can add a custom screen sized to your cap when we install or replace it, and we’ll match the mesh to the wildlife we actually see in Severn, not whatever generic screen comes in the box. Call (443) 332-7798 and we’ll get you set up before the next nesting season.
