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.

AfterFireplace & Chimney Repair in Corinth, TX
Chimney repair in Corinth typically runs $450 – $1,900 for the most common fixes: $185 – $375 for cap replacement, $900 – $2,600 for flue relining when a liner has rusted through or cracked, and $500 – $1,800 for crown repairs or tuckpointing on brick that has shifted with the ground. Most of what we see in Corinth is not a sweeping issue at all, it is water getting into places it should not be. A chimney that leaks from the roofline down cannot be fixed by sweeping the flue, and that is exactly why we document everything on camera before we ever recommend a repair. If you are in the Corinth area and want a straight answer about what is actually wrong, call us at (830) 251-4560.
We work in Corinth regularly, from the older brick homes along Swisher Road to the 2000s-era subdivisions sprouting up across the Denton and Collin county line. The houses here share a common problem, and it is not bad luck. It is the soil.
Fast, Reliable Chimney Repair Across Corinth
Corinth sits on heavy black clay that swells when it rains and shrinks when it dries. That cycle puts real pressure on every chimney in the city, and we see the results every week: cracked crowns, open mortar joints, flashing pulled loose at the roofline, and liners that have shifted or rusted through far earlier than they should. A chimney on a Corinth home is working harder than the same chimney would on the sandy soils farther west. It needs a repair crew that knows exactly what those soil conditions do, and that checks the right things first. Call (830) 251-4560 and we will put a date on the calendar for you.
Our team arrives on time, in uniform, and the first thing we do is look. Not quote, not upsell, just look, with a camera, at the crown, the flashing, the cap, and the full length of the flue. You get a written price before any work begins, and you get a photo report showing what we found. That is how we operate in Corinth, and it is the only way we know how to do it.
Flint Chimney Sweep: Done Right Since 2002
Flint Chimney Sweep has been repairing chimneys since 2002, and we operate under The Garrison Standard, the same written operating code every Garrison Partners location follows. That means background-checked, uniformed technicians on every call, a written price before any tool comes off the truck, and a 365-Day Done Right Promise on every repair we make. If a covered repair fails within one full year, we come back and make it right at no charge. No argument, no follow-up invoice, no caveats. Our owner, Hank Delano, built this company on a simple idea: a chimney repair company should be as disciplined as the tradespeople who work for it.
We do not run promotions that expire this week. We do not quote a price over the phone and then change it at the door. The number you approve is the number on the invoice, period. Corinth homeowners have told us that alone is worth more than a lower bid from a company that cannot be reached after 5 p.m.
Chimney Repair Services in Corinth
These are the repairs we perform most often in Corinth, and the price ranges we quote here are what most homes in this city can expect. Every repair starts with a camera inspection, because we will not recommend work we cannot show you.
Mortar Repointing
Repointing, or tuckpointing, is the process of cutting out deteriorated mortar joints and replacing them with fresh mortar that matches your existing brick. On Corinth homes, mortar joints crack because the clay soil under the foundation moves, and that movement transfers upward into the chimney. A typical repointing job in Corinth runs $500 – $1,800 depending on how many joints are affected. Repointing stops water from entering the brick and freezing, which is what turns a small crack into spalled brick. Left alone, that spalled brick is exactly what leads to a full Chimney Repair rebuild down the road.
Spalling Brick Repair
Spalling is when the face of the brick pops or flakes off, usually because water has penetrated the brick, frozen, and expanded. Corinth sees enough freeze-thaw cycles in an average winter to make this a real problem. A single spalled brick can often be replaced for $150 – $400. When spalling covers a wide area of the stack, the chimney may need partial rebuilding, which runs $1,200 – $3,800 in this market. We use Olympia Chimney and Copperfield materials on most brick repair jobs in the Corinth area, selected because they match the local brick stock well.
Chimney Waterproofing
Waterproofing a chimney means applying a vapor-permeable sealant to the brick and mortar so water stays out while moisture inside the chimney can still escape. It is one of the most under-recommended repairs we make in Corinth, and one of the most effective. Given the amount of rain this area gets and the clay soil holding moisture against foundations, water is the single biggest enemy of a Corinth chimney. A full waterproofing treatment typically runs $400 – $1,100 depending on chimney size and condition. We use products that will not trap moisture in the brick, which is the difference between waterproofing done right and waterproofing that causes more damage than it prevents.
Flashing Repair
Flashing is the metal that seals the gap where the chimney meets the roof. When it fails, water runs straight into the chase or down the outside of the flue. On many Corinth homes built since the early 2000s, the original flashing was installed by roofers, not chimney people, and it fails at the corners. We see this on houses all over the city, from the neighborhoods near Lake Lewisville to the newer builds east of I-35E. Flashing repair in Corinth runs $300 – $900 for most homes, and this is a repair we make often when a homeowner first notices a water stain on the ceiling near the fireplace, which is almost never the roof leaking. It is the flashing.
Chimney Rebuilding
When a chimney stack is too far gone to patch, rebuilding is the only option that is actually safe. We rebuild from the roofline up, or from the firebox up, depending on where the failure is. On older Corinth homes near the Lake Cities area, we often find that the stack has been soaking up water for a decade or more, and repointing would be like putting a bandage on a broken bone, so we are more likely to recommend a rebuild. A roofline-up rebuild in Corinth typically runs $1,800 – $4,500. A full firebox-up rebuild runs $3,500 – $9,000. These are the biggest jobs we do, and every one of them comes with the same written 365-Day Done Right Promise as a $300 flashing repair.

Chimney Cap Replacement in Corinth
Chimney cap replacement in Corinth is one of the most common calls we get, and it is also one of the most overlooked until water stains show up on the ceiling. A cap does two jobs: it keeps rain and animals out, and it stops wind from pushing smoke back down the flue. When a cap rusts through, which happens faster here because of our humidity and the amount of rain the Corinth area gets, water drops straight into the flue and mixes with creosote to form an acidic sludge. That sludge eats through liners faster than anything else we see. Replacing a cap in Corinth usually runs $185 – $375 for a standard stainless cap from Copperfield or Olympia Chimney. If the cap has rusted to the point that it has damaged the liner beneath it, the repair cost goes up accordingly, and that is something we will catch on camera and show you before we ever propose a number.
Cap Sizing and Material Choice
A cap that does not fit the flue or the crown properly is worse than no cap at all, because it can restrict draft and create a backdraft hazard. We size every cap to the actual flue opening, not the chimney exterior. The caps we use in Corinth are stainless steel, because galvanized caps rust out in a few seasons here.
Animal Entry Protection
Squirrels and birds find their way down uncapped flues in Corinth all year round, and once they are in, they cannot always get back out. A properly installed cap with the right mesh size keeps them out without restricting airflow. We see this most often in the Spring, but the fix is the same any month of the year.
Chimney Liner Installation in Corinth
Chimney liner installation in Corinth is a repair we make when the flue has rusted through, cracked, or was never properly lined in the first place. Many Corinth homes built during the construction boom of the mid-2000s used factory-built or single-wall liners that corrode much faster than the stainless systems we install today. When a liner goes, the chimney is no longer safe to burn. Carbon monoxide and hot gases can seep into the house through the gaps. Liner replacement in Corinth runs $900 – $2,600 for most homes, depending on flue size and whether the old liner can be pulled cleanly. We install DuraFlex stainless liners on nearly every job, because they are the same professional-grade system our crews trust on their own homes.
Stainless vs. Single-Wall
A stainless liner is double-walled, insulated, and sized to your appliance. A single-wall liner is exactly what it sounds like: a single thin sheet of metal with no insulation and no tolerance for moisture. If your Corinth home has a single-wall liner and it is more than about 15 years old, it is on borrowed time, and we will show you the rust on camera during the inspection.
Same Flue, New Liner
Most liner installations do not require tearing out the old brick. We pull the old liner, clean the flue, and install the new DuraFlex system through the existing opening. The whole job usually takes a single day, and the result is a chimney that drafts better and burns cleaner than it did when the house was new.
Trusted Brands We Service in Corinth
We work with DuraFlex, Olympia Chimney, and Famco products on a daily basis in Corinth, and we stock most common parts locally, which means no three-week wait for a cap or flashing kit that has to ship from across the country. DuraFlex is our standard for liner replacement. Olympia Chimney and Famco supply the caps and terminations we use on most Corinth jobs. These are professional-grade brands with published specifications, and if you want to look them up before we arrive, that is fine with us. We specify product by what the job actually needs, not by what we happen to have on the truck.
Common Chimney Repair Problems We See in Corinth Homes
- Clay-soil movement cracking the crown. Corinth sits on expansive black clay that shifts between wet and dry seasons, and that movement transfers into the chimney. Crown cracks let water into the flue, and the fix is crown repair or replacement, not a sweep.
- Rusted-through flue liners. Builders around Corinth often installed factory-built or single-wall liners that corrode from the inside out. A homeowner sees smoke in the house and assumes the chimney needs sweeping, when the liner itself is gone.
- Failed flashing at the roof chase. Homes built in the 2000s all over Corinth, particularly in subdivisions near Swisher Road and the areas east of I-35E, often have flashing that was installed incorrectly or has pulled loose over time.
- Third-degree glazing in smoke chambers. Water entering through a rusted cap or failed flashing mixes with creosote and creates a hardened glaze. This is not a brushing problem. Glazed creosote requires chemical treatment and careful removal, or it is a chimney fire waiting to happen.

FAQs About Chimney Repair in Corinth
Once a year, and not because we are trying to sell you an annual contract. The National Fire Protection Association recommends an annual inspection of all chimneys, fireplaces, and vents, and the clay soils around Corinth make that recommendation here more important than in most places. The crown and flashing move every season, and an annual photo inspection catches the movement before it becomes a leak. A sweep is usually needed every one to three cords of wood burned. If you burn a fire every weekend from November through February, plan on a sweep every year. Call (830) 251-4560 to book a sweep or inspection.
A Level 2 inspection includes everything in a Level 1 inspection, plus a camera scan of the entire flue, the smoke chamber, the damper, and the exterior crown and flashing. In Corinth, we recommend a Level 2 any time a home changes ownership, after any chimney fire, or when a homeowner notices water stains, smoke smell, or damaged brick. The camera scan is how we find rusted liners and cracked flue tiles that a visual inspection from the roof would miss. If we cannot show you the damage on a screen, we will not ask you to pay for the fix.
Yes. Many of our Corinth customers schedule liner and cap work during the workday and are not home when we arrive. You get the written quote before the work is scheduled, you approve it by phone or email, and we send a photo report showing the finished job when we are done. If anything on the job changes, we call you before we go forward. We do not make a judgment call on your money without talking to you first.
Usually not. A smoke smell with the damper closed, especially on warm days when there is no fire burning, typically means you have a draft problem or a liner problem, not a cleanliness problem. In Corinth, we often find that the smell is coming from creosote deposits in the smoke chamber that are being warmed by the sun, or from a rusted liner that is no longer drafting properly. The fix might be a sweep, or it might be a liner replacement. The only way to know is to put a camera in the flue and look.
Third-degree creosote is a hard, shiny glaze that looks like tar, and no, it cannot be brushed off with standard sweeping tools. It forms when water mixes with creosote and the mixture bakes onto the flue walls, which is why it is so common on Corinth chimneys that have had a leaking cap or flashing. Removing third-degree creosote requires chemical treatment followed by aggressive mechanical cleaning, and if it is thick enough, the liner may need replacement. We will show you the glaze on camera during the inspection. Call (830) 251-4560 if you suspect your chimney has creosote buildup, and we will give you a straight answer.
