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 Repair Across Jessup
Most chimney repair in Jessup comes down to this: the chimney was built for oil or coal heat in 1962, a gas insert went in during the 1990s, and nobody ever checked whether the flue still matched the appliance. The result is cracked clay tiles, stalled draft, and creosote staging that looks alarming on a camera but usually has a straightforward fix. Wendell Pike and his crew at Top Hat Chimney have been sorting out exactly this kind of mismatch since 1999. We work the Route 1 corridor every week, and when you call (443) 332-7798, a live person answers. No call center, no voicemail maze. We’ll give you a straight price before a single tool comes off the truck, and we back the work with our 90-Day Done Right Promise in writing.
Why Top Hat Chimney Is Jessup’s Preferred Chimney Repair Company
Ask anyone on your street who has dealt with a national chimney outfit. They’ll tell you about a quote that changed at the door, a technician who couldn’t answer basic questions about the county line, and a phone number that stopped getting answered once the check cleared. That’s not how Wendell runs a business. Top Hat Chimney is locally owned and owner-operated, founded in 1999, and Wendell puts his name and license number on every job because he runs into you again at the hardware store and the community center. We don’t get to disappear.
For Jessup specifically, there’s a real advantage to working with a chimney contractor who already knows the area. Howard County and Anne Arundel County split Jessup down the middle, and we confirm which county governs your address before we file anything. That saves you from a failed inspection and a callback on a liner job that should have been routine. Our crews arrive in uniform, background-checked, and we give you a real arrival window. If it slips, we call. You won’t sit around wondering.
One more thing worth knowing: we answer the phone 24/7. If you call at three in the afternoon or three in the morning, a person picks up. Often it’s Wendell himself. And when it comes to pricing, the number you hear on the phone is the number on the invoice. Standing offers include $40 off any repair over $200 and a free second opinion on any competing written estimate. Seniors and veterans always get 10% off.
Our Chimney Repair Services in Jessup
Mortar Repointing
Jessup’s older brick chimneys, especially the mid-century colonials and ranchers off Route 1, lose mortar joints to the same freeze-thaw cycle every winter. Humidity from the Patuxent watershed settles into the brick, freezes, expands, and crumbles the joints from the inside out. Mortar repointing in Jessup typically runs $15 to $30 per square foot of masonry area, depending on access and joint depth. We match the original mortar mix so the repair doesn’t stand out like a patch. Skipping this work is how a $600 repointing turns into a $4,000 rebuild.
Spalling Brick Repair
Spalling is when the face of the brick pops off, and you’ll see red chips and grit collecting at the chimney base or on the roof flashing. Around Jessup, the ground moisture near the lower Patuxent River watershed wicks up into chimney bases and accelerates exactly this kind of damage. A typical spalling brick repair job in Jessup runs $500 to $1,800 depending on how many bricks need replacing and whether the damage has reached the smoke chamber. We’ll show you the camera footage before we recommend anything. If it’s cosmetic, we’ll tell you that and let it wait a season.
Chimney Waterproofing
Brick is porous. Water gets in, freezes, and breaks things. A chimney waterproofing treatment in Jessup usually costs $400 to $900 for a standard residential stack, and it’s one of the few chimney jobs that genuinely pays for itself in prevention. We use breathable waterproofing products that keep water out while letting the masonry release moisture, which matters in this humid corridor between Baltimore and DC. One application typically holds for seven to ten years, and we’ll document it so you know exactly when it’s due again.
Flashing Repair
Roof flashing failures are one of the most common chimney repair calls we get in Jessup, especially after a hard winter. The thin metal that seals the chimney where it meets the roof takes years of expansion and contraction, and once it lifts or tears, water starts running into the attic and down the chase. Flashing repair in Jessup runs $450 to $1,200 for most residential setups. We replace it right, with proper counter-flashing and a watertight seal, and we don’t caulk over visible gaps and call it done.

Trusted Brands We Service in Jessup
We install and service chimney systems from manufacturers we trust, because the liner that goes into your Jessup chimney has to handle what your appliances actually produce. That means brands like DuraFlex for stainless steel liners sized to your flue, HeatShield for ceramic resurfacing when a full liner would be overkill, and Copperfield for caps, shrouds, and chimney top components. Because we work with these brands constantly across the Route 1 corridor, we can usually get the parts we need on the truck for your appointment rather than making you wait on a warehouse. When a liner job is scheduled in Jessup, we bring what we need the first time.
Common Chimney Repair Problems We See in Jessup Homes
- County line confusion. A meaningful number of Jessup residential addresses carry a Howard County mailing identity but legally sit in Anne Arundel County. We verify which county governs your address before filing liner work or cap replacement. A contractor who skips that step files under the wrong authority, and you get a failed inspection and a rescheduled job that looked routine.
- Oversized clay flues on gas-converted chimneys. Many Jessup homes built between the 1940s and early 1970s switched from oil or coal to gas without relining. That leaves an 8×12 clay tile flue venting a small gas appliance, which stalls draft, lets exhaust condense inside the flue, and accelerates cracking and creosote staging. First-degree creosote is a brush job. Third-degree is a glaze you don’t want to see on the camera.
- Freeze-thaw spalling near the watershed. Jessup sits low between Baltimore and DC, in the lower Patuxent River watershed, and the above-average ground moisture finds its way into chimney bases. Efflorescence and brick face loss get mistaken for cosmetic wear until a camera shows the structural damage hiding behind it.
- Unlined smoke chambers. Older Jessup chimneys were often built with corbeled brick smoke chambers and no modern parge coating or liner. Heat and creosote accumulate in the gaps between the corbels, and that’s where chimney fires start. We rebuild smoke chambers with modern refractory parging that gives the chimney a smooth, continuous path.

FAQs - Chimney Repair in Jessup
A Level 2 camera inspection is the only honest way to answer that question. The camera shows whether your clay tile flue is cracked, spalling, or sized wrong for the appliance venting into it. In Jessup specifically, we see a lot of mid-century gas conversions where the flue is too big for the appliance, and that mismatch causes damage that a repair won’t fix. If the clay tiles are cracked and separated, a stainless liner is the correct fix. If the flue is intact but leaking exhaust gases into the masonry, HeatShield resurfacing may do the job for less. We’ll show you the footage and give you a plain-English verdict. Call (443) 332-7798 and we’ll schedule the inspection.
You can’t tell from the mailing address, which is exactly the trap. We check the county line on every Jessup job before filing anything, because a surprising number of addresses carry a Howard County mailing identity but sit inside Anne Arundel County jurisdiction. We verified a 1950s brick rancher off Old Jessup Road before pulling a liner permit and it sat on the Anne Arundel side. A contractor who files under the wrong county gets a failed inspection and a rescheduled job. We don’t let that happen. If you want us to check your address, call (443) 332-7798 and we’ll look it up while you’re on the phone.
Because the freeze-thaw cycle in this humid corridor between Baltimore and DC keeps working on the joints every winter. Jessup sits low, near the Patuxent watershed, and the ground moisture finds its way into chimney bases and brick faces. When water freezes inside the mortar, it expands and pops the joint loose. Repointing done with the correct mortar mix for your specific brick will last a good long while, but the climate here means older chimneys need to be re-inspected and touched up more often than in drier areas. That’s simply what the weather does. Call (443) 332-7798 to have us look at your mortar joints before the next freeze.
First-degree creosote is a light, brushable soot that a standard sweep removes. Third-degree creosote is a hardened glaze that forms when gas exhaust condenses inside an oversized flue, and it’s a genuine chimney fire hazard that no brush will remove. In Jessup, the oil-to-gas conversions in mid-century Route 1 homes set up exactly the conditions for glaze to form, because the flue is too large for the appliance and the exhaust cools and condenses before it exits. Catch it at first-degree and you’re looking at a simple sweep. Let it sit for a decade and you’re looking at a liner or chemical treatment. Call (443) 332-7798 to schedule an inspection and see what stage your flue is at.
No, and for a reason that surprises a lot of Jessup homeowners: chimneys break in the off-season too. The freeze-thaw cycles, the ground moisture, and the wildlife that moves into an unused flue all keep working when you aren’t burning. We recommend an inspection once a year, burn or no burn. The inspection is inexpensive compared to discovering a cracked flue or a spalled smoke chamber after the damage has spread. Call (443) 332-7798 and we’ll get you on the schedule.
