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.

Why Emberly Chimney Cleaners Denton Is Lewisville’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been in Lewisville’s 1980s-1990s subdivisions where the same prefab systems fail on predictable timelines. Our Lewisville customers consistently mention the camera footage in their reviews - they want to see what we found, not take our word for it.
Response time to Lewisville runs 2-4 business days for standard repairs, with emergency calls for active leaks or suspected carbon monoxide issues prioritized same-day. Every technician is background-checked, uniformed, and assigned by name; you get a text when they’re on the way, and their license number is on the paperwork.
We know the local housing stock. The tract developments off FM 407, the older Castle Hills builds, the Valley Vista corridors - these aren’t masonry chimneys. They’re zero-clearance prefab units with galvanized steel chase enclosures that were never designed to last 35 years. That local knowledge changes what we look for, what we quote, and what we recommend.
Our Chimney Repair Services in Lewisville
Mortar Repointing
True masonry chimneys are rare in Lewisville’s core residential areas, but they do appear in some 1990s custom builds and in homes near Old Town. Where we find them, mortar joints between brick courses deteriorate from North Texas thermal cycling - 100°F summer days to hard freezes in winter. Repointing in Lewisville runs $18-$28 per square foot of joint surface, with most residential jobs falling between $450 and $1,200. We grind out failed mortar to a 3/4-inch depth, match the original mix for color and compressive strength, and document the before-and-after under Haven Standard Clause 4.
Spalling Brick Repair
Spalling - brick faces flaking off from moisture freeze-thaw damage - shows up on Lewisville’s few masonry chimneys and on the brick veneer surrounding prefab chase enclosures. In the Highlands subdivision and similar 1980s builds, we’ve seen spalling where chase cover leaks have saturated the brick for years. Individual brick replacement runs $35-$65 per brick including mortar matching; partial rebuilds of damaged courses range from $800 to $2,400 depending on access and scaffolding needs. We don’t quote masonry repair without first confirming the water source is fixed.
Chimney Waterproofing
This is where Lewisville’s prefab-heavy housing stock gets misunderstood. Most “chimney leaks” here aren’t masonry absorption problems - they’re chase cover failures, flashing gaps, or rotted OSB sheathing behind siding. But where we do find porous brick or where a masonry crown has hairline cracks, we apply vapor-permeable waterproofing sealers from Olympia Chimney and Copperfield that let the wall breathe while blocking liquid water. Application runs $380-$650 for a typical residential chimney. On prefab systems, we often pair this with chase cover replacement and proper counter-flashing to stop the actual water source. Waterproofing alone won’t fix a rusted chase cover.
Flashing Repair
Lewisville’s wind-driven rain events, particularly in spring and fall, exploit gaps where chimney flashing meets the roof plane. On prefab chase chimneys, the original builder-grade flashing is often step-flashing only, without counter-flashing or a proper cricket on the uphill side. We fabricate custom flashing from 26-gauge galvanized steel or copper, integrate it with the existing roof system, and seal with high-temperature polyurethane. Typical flashing repair or replacement in Lewisville runs $320-$780. On older homes near Main Street and the 75057 zip, we’ve found original flashing that was never properly integrated with the roof decking at all.

Common Chimney Repair Problems We See in Lewisville Homes
- Rusted-through chase covers on 25-30-year-old prefab systems. The original galvanized steel covers in Lewisville’s 1980s-1990s tract homes corrode predictably. We pull covers and find rotted OSB sheathing, rust-stained siding, and sometimes compromised framing - damage that progressed silently for years because the chase exterior looked fine from the ground.
- Cracked refractory panels after sudden cold-snap use. February 2021’s Winter Storm Uri sent thousands of Lewisville homeowners to fireplaces that hadn’t run in years. The thermal shock cracked refractory panels in zero-clearance fireboxes, and some homeowners continued using them unaware that cracked panels can allow combustion gases into wall cavities.
- Chimney swift and wasp nesting in uncapped flues. North Texas mild winters mean Lewisville fireplaces sit idle 8-10 months annually. Uncapped flues become prime habitat for chimney swifts (federally protected April-October), paper wasps, and rodents. Nests restrict draft and hide underlying flue damage from casual inspection.
- Seized or misaligned dampers from disuse. Prefab system dampers in Lewisville’s aging fireplaces corrode or warp when not exercised regularly. A seized damper can’t be opened for ventilation or closed to stop heat loss - either condition wastes energy or creates a safety issue.

FAQs - Chimney Repair in Lewisville
Yes, most likely. Factory-built zero-clearance fireplaces were designed for 20-25 years of service, and Lewisville’s 1980s-1990s tract stock is now 30-40 years old. That doesn’t mean automatic replacement - we’ve serviced prefab units at 35 years that were still structurally sound with proper chase cover and panel maintenance. But it does mean every component should be camera-inspected annually: refractory panels, firebox metal, damper operation, and chase cover integrity. Call (940) 373-6912 to schedule - estimates are free, and we show you the footage before recommending anything.
A Level 1 inspection is a visual check of accessible components - what most companies sell as their “standard inspection.” A Level 2 inspection, which is our default on every Lewisville visit, adds a camera scan of the full flue length, inspection of attics and crawl spaces where accessible, and documentation of all findings with photos - Haven Standard Clause 4 since 2009. A Level 3 inspection involves demolition of building materials to access concealed areas, and we only recommend it when Level 2 evidence suggests hidden hazards. Every Emberly Chimney Cleaners customer in Lewisville receives Level 2 documentation as standard, not an upgrade.
Wind-driven rain in North Texas exploits existing vulnerabilities: lifted flashing edges, cracked or missing chimney caps, deteriorated crown sealant, or rusted-through chase covers. On Lewisville’s prefab systems, the most common cause is a chase cover that finally failed after years of rust progression - water enters the chase interior, runs down the flue or framing, and appears inside the home or on exterior siding. We find the entry point with camera inspection and water testing, show you the footage, and quote only the repair that addresses the actual source. Call (940) 373-6912 for a leak diagnosis - estimates are free.
No. Nothing is recommended without camera evidence you can see for yourself, and we explicitly tell Lewisville homeowners when work can safely wait. In a market where upselling is common, our Haven Standard requires documented justification for every line item. Waterproofing is only quoted where porosity testing or visible absorption confirms it’s needed. Repointing is only quoted where mortar joints fail a probe test. Rebuilds are rare in Lewisville’s prefab-dominant market and only suggested when structural integrity is compromised beyond component-level repair. The written scope, written price, and written warranty all arrive before any work begins - Clause 1.
Schedule a Level 2 inspection before the next use. In Lewisville, we see this pattern constantly: systems idle for 8-10 months, then sudden heavy use during events like Winter Storm Uri reveals cracked refractory panels, seized dampers, or blocked flues from animal nesting. These aren’t minor maintenance items - cracked panels can allow combustion gases into wall cavities, and blocked flues can force carbon monoxide back into the living space. A camera scan takes 45 minutes and gives you a documented record of what’s actually happening inside the system. Call (940) 373-6912 to book - estimates are free, and we’ll tell you plainly if the system is safe to use or needs repair first.
