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 Lewisville
A cracked chimney crown or missing cap in Lewisville usually means water is already working its way into your flue, and on the Blackland Prairie clay that underlies most of this city, the damage compounds faster than in neighboring towns. A typical crown repair in Lewisville runs $450-$900, and a standard stainless steel cap with installation runs $280-$520 depending on flue size. If you’ve noticed spalling brick, rust stains, or water in the firebox, call (980) 580-8641 and we’ll send a background-checked technician with a camera, not a clipboard.
Why Emberly Chimney Cleaners Is Lewisville’s Preferred Chimney Cap & Crown Company
Lewisville homeowners are not impressed by a company’s founding year. They want to see what’s wrong before they pay to fix it. That’s exactly how we work. Every Chimney Cap & Crown visit includes a camera scan down the flue and a documented photo record you keep, so when we tell you the crown is cracked or the cap is rusted through, you’re looking at the same image we are.
Our crews know Lewisville’s neighborhoods, from the 1980s tract subdivisions east of I-35E to the older brick ranches along Valley Ridge Blvd and the newer builds near Lake Park. Corrine Halstead has built our inspection standard around one rule: nothing gets recommended without visual proof. That matters in a city where expansive clay soil moves chimneys in ways a flashlight inspection would never catch.
We’re not the cheapest and we don’t try to be. We’re the company that hands you a written price, a written scope, and a written warranty before anyone touches a tool. Clause 1 of the Haven Standard has required that since 2009. Lewisville customers also get a text when the named tech is on the way, so you’re never waiting on a three-hour arrival window.
Our Chimney Cap & Crown Services in Lewisville
Cap Installation
A missing or undersized cap on a Lewisville chimney lets North Texas rain and summer humidity sit inside the flue for months at a stretch. We install stainless steel caps from Famco and Olympia Chimney, sized to your flue tile and secured against the wind gusts that sweep across the prairie. Standard single-flue cap installation in Lewisville runs $280-$420.
Cap Replacement
We replace rusted, bent, or animal-damaged caps throughout Lewisville, including multi-flue caps for homes with two or more flues sharing one chimney. If your cap is more than 10 years old and you can see daylight through the mesh from the ground, it’s past time. A replacement cap on a standard masonry chimney runs $320-$520 depending on whether it’s a single-flue or multi-flue application.
Crown Repair
This is the most common job we do in Lewisville, and the one most directly tied to the local soil. The expansive clay under your slab heaves seasonally, and that movement travels up the chimney structure. Crowns crack, water enters the mortar bed, and the freeze-thaw that northern chimneys suffer is replaced here by a slower but relentless shrink-swell cycle. Crown repair in Lewisville typically runs $450-$900. We use Gelco crown coat systems designed for exactly this failure mode.
Crown Coating
A properly mixed and sloped concrete crown still benefits from a flexible elastomeric coating that moves with the chimney instead of cracking against it. In Lewisville’s climate, uncoated crowns fail in under a decade. We apply Gelco coating after repairing the crown substrate, and we document the finished surface with photos before we leave. Coating a standard residential crown runs $250-$450.
Custom Cap & Multi-Flue Cap
When your chimney has an unusual flue layout or you want a cap that actually fits instead of a universal one bent to “close enough,” we order custom caps through Famco and Copperfield. Custom multi-flue caps for Lewisville homes run $600-$1,100 installed. The price includes exact field measurements and a written drawing of what’s being fabricated, so you approve the design before it’s built.

We stock and install parts from Famco, Gelco, and Olympia Chimney because they hold up to North Texas weather and we can get replacements fast when a Lewisville customer needs one. We don’t push universal-fit parts when a custom piece is the right call. Our suppliers are procured through Haven’s buying network, which helps keep our prices honest on the invoice, not just in the estimate.
Common Chimney Cap & Crown Problems We See in Lewisville Homes
- Clay-soil crown cracking: The Blackland Prairie clay under most Lewisville slabs expands and contracts with moisture, and that movement travels up through the chimney. Crowns crack even when the fireplace never fires. The crack then channels water directly into the mortar bed and flue.
- Rusted-through dampers and caps from dormant flues: A fireplace that sits unused for 8-9 months of mild weather is a humidity trap. Without a functioning cap, steel dampers rust through and clay tile liners spall from the inside out. We see this constantly in 1970s and 1980s homes that never had a chimney inspection.
- Separated flashing without any fire history: Lewisville techs regularly find flashing pulled away from the roofline on homes where the fireplace has literally never been used. The slab moves, the chimney moves with it, and the connection at the roof line takes the stress. It looks like storm damage. It’s the soil.
- Hardened third-degree creosote after sudden cold snaps: When February 2021 hit, thousands of Lewisville fireplaces that hadn’t been lit in years were suddenly burning daily. The creosote inside had hardened into a glaze that a standard brush can’t remove. A cap and crown repair on one of these chimneys is pointless without addressing what’s inside the flue first.

FAQs - Chimney Cap & Crown in Lewisville
The crowns crack because Lewisville sits on expansive Blackland Prairie clay, which swells when wet and shrinks when dry. That seasonal movement heaves your slab, and the chimney moves with it. A crown that’s uncoated or sloped wrong will crack from this movement alone, no freezing required. Call (980) 580-8641 and we’ll show you the crack with a camera before we recommend any repair.
The slab under your home moves seasonally, and the chimney sits on that slab. Even with zero fires, the shrink-swell cycle stresses the chimney’s connection to the roofline and the firebox masonry. This is a known failure mode in Lewisville’s older tract subdivisions east of I-35E. We see it on first inspections all the time. The good news is it’s repairable, and we’ll document the condition with photos before and after.
Yes. A fireplace that sits dormant for 8-9 months in North Texas humidity is collecting moisture inside the flue whether you burn or not. A missing or damaged cap lets rain, humidity, and animals in. We regularly pull rusted dampers and spalled clay tiles out of Lewisville chimneys that haven’t seen a fire in years. A cap costs a few hundred dollars. A flue liner replacement runs into the thousands.
Third-degree creosote is a hardened, glazed tar that forms when creosote bakes under repeated hot fires and then cools. It’s common in Lewisville because fireplaces sit unused for months, creosote cures in the humidity, and then a sudden cold snap drives heavy burning. It can’t be removed with a standard brush. We’ll show you the camera footage before recommending a removal method. Call (980) 580-8641 for a free inspection and written estimate.
Because the clay under your home keeps moving. A concrete crown repair stops the current crack, but the soil’s shrink-swell cycle will continue stressing that repair. A flexible elastomeric coating like Gelco moves with the chimney and buys you years. Nothing stops the soil from moving. The coating is what keeps water out while it does. We include coating on every crown repair we quote.
