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.

Our Chimney Repair Services in Lewisville
Chimney Rebuilding
True masonry chimney rebuilds are comparatively rare in Lewisville compared to older Texas cities, but when we do encounter them - typically in the small pre-1970 pockets near Old Town - the same freeze-thaw cycling that degrades prefab units attacks mortar joints with equal severity. A partial rebuild addresses the stack above the roofline; a full rebuild starts at the firebox and works up. Either way, we document the existing condition with a camera scan before demolition begins, and we source materials through our Haven buying network to keep prices honest. Most masonry rebuilds in Lewisville run $3,200-$7,500 depending on height and accessibility.
Chimney Waterproofing
North Texas weather is hard on chimneys. The sporadic but intense “Blue Norther” cold fronts deliver rapid temperature swings that open hairline cracks in crown wash and let water migrate behind brick faces. In Lewisville’s prefab-heavy housing stock, waterproofing often means sealing the chase cover seams and applying vapor-permeable sealant to the chase structure itself - because water entering a prefab chase degrades the firebox and surrounding framing from the inside out, long before you see a stain on your ceiling. We use breathable sealants that allow moisture to escape while blocking new infiltration. Typical chase and crown waterproofing in Lewisville runs $450-$890.
Flashing Repair
Flashing is the metal interface where your chimney passes through the roof, and it’s a common leak point in Lewisville homes where roofers and chimney crews sometimes point fingers at each other. We cut our flashing from copper and aluminum stock sourced through Copperfield and install it with proper step-flashing integration into the roofing membrane. Our Chimney Repair team photographs the existing flashing from the attic and the roof before recommending replacement, so you can see the rust, gaps, or tar-band-aid repairs for yourself. Flashing repair in Lewisville typically costs $380-$720.
Mortar Repointing & Tuckpointing
Where we find traditional brick chimneys in Lewisville - again, mostly in older pockets rather than the sprawling subdivisions - mortar repointing removes deteriorated joint material to a proper depth and replaces it with color-matched masonry cement. Tuckpointing goes further, cutting thin decorative lines to simulate fine historic joints. Both require dry conditions and proper curing time, which means we watch North Texas weather windows carefully. Repointing runs $18-$32 per square foot of joint surface in this market.
Spalling Brick Repair
Spalling - the flaking and popping of brick faces - happens when water trapped behind the surface freezes and expands. Lewisville’s freeze-thaw cycles are milder than northern climates but more damaging than many homeowners expect, especially on south-facing chimney stacks that heat all day and cool rapidly when a Blue Norther rolls through. We remove spalled units, inspect the wythe behind for saturation damage, and replace with matching brick. Single-area spalling repair typically runs $650-$1,400.

AfterTrusted Brands We Service in Lewisville
We stock parts and materials from DuraFlex, HeatShield, and Gelco through our Haven buying network, which means Lewisville customers aren’t waiting on cross-country shipping for standard repairs. HeatShield’s cerfractory resurfacing system handles firebox joint restoration in prefab units where full panel replacement isn’t necessary. DuraFlex liners and components cover the minority of Lewisville homes with masonry stacks that need relining. Gelco’s chase covers and caps fit the common prefab chase dimensions we see in 1980s-1990s tract homes. Fast turnaround matters when a cold snap is forecast and your firebox is compromised.
Common Chimney Repair Problems We See in Lewisville Homes
- Refractory panel cracks in zero-clearance fireboxes. The clay-based panels in 1980s-1990s Heatilator, Majestic, and similar units deteriorate from years of Texas heat-and-cool cycling. Hairline cracks run through the joints long before visible damage appears, creating burn-through risks that a flashlight glance won’t catch.
- Corroded chase covers letting water into prefab chases. North Texas freeze-thaw cycles accelerate rust on galvanized steel chase covers, especially on homes within a few miles of Lewisville Lake where humidity runs slightly higher. Water enters the chase, saturates the firebox surround, and can damage ceiling drywall before you notice any exterior problem.
- Separated firebox seams in builder-grade metal fireplaces. Decades of thermal expansion and contraction open seams between metal firebox panels, allowing creosote and combustion gases to reach voids the unit was never designed to tolerate. This is a carbon monoxide pathway, not just an efficiency issue.
- Creosote buildup from cold, incomplete burns during sporadic use. Lewisville’s mild winters mean many homeowners fire up only during Blue Norther events, burning cold wood in a cold firebox with poor draft. The result is heavy, tar-like Class III creosote that accelerates liner and component degradation.

What moves you within these ranges? Height and roof pitch affect labor time. Accessibility - can we get a ladder safely to the stack, or do we need staging? Material choice: copper flashing costs more than aluminum, and custom chase covers run above standard sizes. And the condition we find once we open it up: a chase cover that looked intact from the ground often reveals saturated framing and degraded firebox seams once removed.

FAQs - Chimney Repair in Lewisville
Most 1980s zero-clearance units can be repaired if the firebox wrapper and framing are structurally sound. We replace refractory panels, chase covers, and deteriorated firebox components with OEM or compatible parts rather than condemning the entire unit. On a call in the Vista Ridge area off FM 407, our tech opened up a 1990s Heatilator and found the refractory panels looked fine at a glance, but probing the joints revealed hairline cracks running the full height of the rear panel - the original panels had simply outlived their service window after decades of North Texas heat-and-cool cycling. We replaced the panel set and inspected the firebox seams and chase cover, which had also corroded from freeze-thaw, and documented every step on camera for the homeowner before recommending anything. Call (469) 429-2623 for an exact quote - estimates are free.
Because surface appearance is misleading on panels that have undergone decades of thermal cycling. Hairline cracks at the joints - the most common failure mode in Lewisville’s 1980s-1990s prefab stock - are often invisible until you apply gentle pressure or use a pick to trace the seam. A tech who doesn’t probe systematically misses failures that later become burn-through risks. Clause 4 of the Haven Standard requires a photo record on every job, so we document the probe and any cracks we find. Call (469) 429-2623 for an exact quote - estimates are free.
NFPA 211 Level 2 requires a camera scan of the flue, inspection of accessible portions of the chimney structure, and examination of the appliance and connection. On a Lewisville prefab unit, that means we camera the flue liner if present, inspect the firebox panels and seams with systematic probing, check the chase cover and chase structure for water intrusion, and verify clearances to combustibles. You receive a documented photo record of every finding. Nothing is recommended without evidence you can see for yourself. Call (469) 429-2623 for an exact quote - estimates are free.
That’s Class III creosote, the thick, tar-like deposit that forms from cold, incomplete burns - common in Lewisville where mild winters lead to sporadic fireplace use followed by long idle periods. When humidity rises, the creosote off-gasses, producing that sharp, asphalt-like odor. It’s also the most combustible form of creosote and the type most associated with chimney fires. A Chimney Cleaning & Sweep - Lewisville removes it; a Level 2 inspection determines whether it’s also degraded your liner or firebox components. Call (469) 429-2623 for an exact quote - estimates are free.
No. Haven Standard Clause 4 requires a documented photo record on every job, and Clause 1 requires a written price before work starts. We don’t ask you to trust our word - we show you the cracked panel, the corroded chase cover, the separated seam, the camera footage of the flue condition. If we can’t document it, we don’t recommend it. Some repairs can safely wait; we’ll tell you when that’s the case. Call (469) 429-2623 for an exact quote - estimates are free.
