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.

We know Conroe homes. We know the brick two-stories off League Line Road, the older masonry chimneys near downtown around Frazier Street, and the newer construction spreading through the neighborhoods along FM 3083. What we see most here isn’t rust or full liner failure. It’s crown cracking and flashing separation, and both trace back to Montgomery County’s clay-heavy soil and our hard, wind-driven rains. That local knowledge is why we don’t guess. We camera-inspect, photograph what we find, and put the repair scope and price in writing before a single tool comes off the truck.
Why Flint Chimney Sweep Is Conroe’s Preferred Chimney Repair Company
Our reputation in Conroe is built on the same thing everywhere we work: showing up on time, answering the phone, and standing behind the work in writing. Background-checked, uniformed technicians dispatch to Conroe from our Houston office, and every job starts with a written price you approve before any work begins. No revised number at the door, no “while we’re here we found something else” surprises that double the invoice.
We carry professional-grade materials for the specific problems Conroe chimneys develop: DuraFlex liners when a liner is actually compromised, Copperfield CrownCoat for crown sealing, and HeatShield for targeted flue repair. And our Chimney Repair work is covered by the 365-Day Done Right Promise, a written guarantee valid for a full year. If a covered repair fails inside that year, we return at no charge. That’s The Garrison Standard, and it applies on every job in Conroe, no exceptions.
Chimney Flashing Repair in Conroe
Chimney flashing repair in Conroe is the single most common repair we perform, and it usually costs $350 – $700 depending on how much of the flashing needs resetting versus replacing. Flashing is the metal barrier where the chimney meets the roofline, and in Conroe it takes a beating from wind-driven rain sweeping off the open spaces west of I-45. When step flashing lifts or counter-flashing separates, water tracks down the chase and shows up as a ceiling stain ten feet away from the chimney, which confuses homeowners who assume the leak is the roof’s fault.
What flashing failure looks like
Water stains on the ceiling near the chimney, damp drywall around the chase, or rust staining on the brick just below the roofline. In Conroe’s wet springs, homeowners often mistake flashing leaks for roof leaks and call a roofer first. The roofer patches shingles, the stain comes back, and then we find the actual problem: step flashing pulled loose by storm winds or old sealant that’s failed after years of thermal expansion and contraction.
How we fix it
We remove the old flashing, inspect the underlying roof decking for rot, then reset or replace the step flashing and counter-flashing with proper overlap. Every flashing repair includes a water test and a written report on what we found. If the flashing was compromised long enough to damage the chase exterior, we’ll document that separately with photos so you know exactly what needs attention now versus what can safely wait.
Chimney Crown Repair in Conroe
Chimney crown repair in Conroe ranges from $400 – $900 for a full crown seal with Copperfield CrownCoat, and it’s the other half of the two most common fixes we do in this city. The crown is the concrete shelf at the top of the chimney that sheds water away from the flue and brick. Montgomery County’s expansive clay soil shifts through wet-dry cycles, and that movement transfers up through the chimney structure. Crowns crack, water gets in, and freeze-thaw cycles through our mild but wet winters spall the concrete and the brick below it.
Why Conroe crowns crack early
A crown that would last twenty years in stable soil might crack in ten here, because the ground under the footing expands when saturated and contracts when dry. The chimney moves as one unit, and the crown, being the most rigid single piece, takes the stress first. Once a hairline crack opens, water follows gravity into the chimney chase, and the damage compounds every year.
When a crown can be sealed versus rebuilt
Hairline cracks and surface spalling can usually be repaired with CrownCoat, a flexible sealant that moves with the chimney through seasonal cycles. If the crown is badly deteriorated, cracked through, or missing large sections, we’ll rebuild it with a proper overhang and drip edge so water sheds away from the brick. We’ll tell you plainly which route is needed, and we’ll show you the camera footage that backs up the recommendation. No scare-selling. No unnecessary tear-outs.
Trusted Brands We Service in Conroe
We install and work with materials from manufacturers that publish their specs and stand behind their products: HeatShield for flue resurfacing, Gelco for chase covers, and Copperfield for crown repair. When a Conroe chimney needs a liner replacement, we use DuraFlex because it’s flexible enough to snake through Conroe’s older brick flues that settle and shift with the soil, and durable enough to carry a manufacturer’s warranty we pass through to you. Parts for common repairs are stocked in our Houston office and arrive with the technician, which means most Conroe jobs are done in one visit without a second trip to “come back with materials.”
Common Chimney Repair Problems We See in Conroe Homes
- Crown cracks from expansive clay soil. Montgomery County’s clay-heavy ground swells when wet and contracts when dry, and that cyclical movement stresses chimney crowns until they crack. Water entry through a cracked crown is the most preventable cause of larger chimney damage in Conroe.
- Flashing lifted by wind-driven rain. Storms push rain horizontally off the open fields west of I-45, and step flashing that would hold fine in a normal rain gets pried loose. The leak often shows up far from the chimney, so homeowners chase the wrong problem.
- Creosote buildup that exceeds a simple sweep. Homes that burn wood only a handful of times per year still build first-degree creosote, and skipped annual inspections let it glaze over into second-degree buildup that a standard sweep can’t fully remove. A repair-grade cleaning is what’s needed before burning safely again.
- Animal nests blocking the flue. Squirrels and birds find Conroe’s older chimneys with missing or damaged chimney caps. By the time draft problems show up, the nest is often packed, and the flue needs to be cleared and the cap replaced.

FAQs About Chimney Repair in Conroe
Once a year, even if you only burn a few times each winter. The NFPA 211 standard recommends annual inspection, and in Conroe the main risks aren’t just creosote. Crown cracks from our clay soil movement and animal nesting are common, and both get caught early in a routine inspection. A chimney that only gets looked at “when something seems wrong” usually costs more to fix when it finally gets looked at. Call (830) 251-4560 to schedule an inspection.
We’ll give you the honest answer, which is a price range like the ones above, but not a firm number. A crown repair could be $400 or it could be $900, and we won’t know until we inspect what’s actually cracked, how deep it goes, and whether the flue liner is affected. What we can promise over the phone is that the written estimate is free, and the price we quote after inspection is the price you approve before work begins. No phone estimate is ever a bait-and-switch to get a higher number at the door because there is no higher number at the door.
Crown repair addresses only the top concrete shelf. A full rebuild means the chimney structure above the roofline is torn down and reconstructed, usually because the brick itself is compromised from years of water intrusion. In Conroe, we see far more crown repairs than full rebuilds, because our local failure mode is soil movement cracking the crown, not catastrophic structural rot from decades of salt air like coastal towns. A crown seal runs $400 – $900. A rebuild runs $4,000 and up. We’ll camera-inspect and show you exactly which one you need, and if the crown can safely wait a season, we’ll say so.
We do not promise same-day repair, and we’d rather be straight about that than disappoint you. We schedule repair work in order, and in busy fall and winter seasons in Conroe, the wait is typically a few days to two weeks. What we do promise is that a live person answers the phone 24 hours a day to get you scheduled, and the technician arrives inside the window given, uniformed and background-checked. If your situation is genuinely urgent, like water actively pouring into the house during a storm, tell the phone team and we’ll talk through options for temporary protection until we can get a crew there.
In Conroe, it’s more often flashing. Heavy spring storms with wind-driven rain push water through lifted step flashing on the uphill side of the chimney, and the leak shows up during the storm and stops when the rain stops. A crown crack leak is slower, more persistent, and shows up days after rain as a gradual stain that never fully dries. We can’t tell you which one it is without looking, but we can tell you that around here, if it only leaks during hard wind-driven rain, flashing is the first thing we check. Call (830) 251-4560 and we’ll camera-inspect before recommending anything.
