Frequently Asked Questions

A chimney sweep removes creosote and soot from the flue walls, smoke chamber, damper, and firebox using rotary brushes sized to your flue. We lay down drop protection around your hearth, connect a HEPA vacuum to control dust inside your home, and sweep from either the roof or the firebox depending on your chimney design. After the sweep, we inspect the damper, cap, crown, and flue liner, then show you what we found. The whole process usually takes 45 to 90 minutes, and the room looks cleaner when we leave than when we arrived. That's the standard, every time.

Plan on 45 to 90 minutes for a standard fireplace and flue. Houses in areas like The Woodlands or Sugar Land with taller chimneys, steeper roofs, or flues that haven't been swept in years can run closer to two hours. If we're doing a camera inspection at the same time, add 20 to 30 minutes. We'll give you a clear arrival window when you book, and we'll show up inside it. The job moves faster than most homeowners expect, and you'll get the full report as soon as we're done.

Just make sure the area around your fireplace is clear so our drop cloths can lay flat and we have room to work, and move anything fragile off the mantel. Don't build a fire for at least 24 hours before your appointment; a cold firebox is faster and safer to clean. If your chimney is tall or has tricky roof access, lock up any pets that might get spooked by ladders or rooftop foot traffic. Other than that, we handle everything else, including sealing off the fireplace opening to keep soot from drifting into your living room.

It shouldn't be, and with our process it isn't. We run HEPA-filtered vacuums the whole time, use drop cloths that extend well beyond the hearth, and seal the fireplace opening while we work. Soot and creosote get vacuumed as they're knocked loose, not left to settle on your carpet. When we're done, we clean up our equipment, haul out everything we brought in, and leave the space squared away. If you've had a sweep before that left your living room dusty, that's the difference between doing it right and cutting corners, and we don't cut corners.

The National Fire Protection Association says chimneys should be inspected at least once a year and cleaned whenever creosote buildup reaches 1/8 inch. For most Houston homeowners who burn wood a few times a month during our mild winters, an annual sweep is the right cadence. If you burn pressed logs, pine, or use your fireplace heavily from November through February, you may need a mid-season sweep too. Gas fireplaces need less frequent sweeping but still benefit from an annual inspection to check the damper, venting, and connections. A yearly rhythm catches problems early, and it keeps your fireplace ready for the first cold snap.

Yes, and in Houston gas log setups are some of the most common fireplaces we service. The flue still needs to be checked for debris, bird nests, and venting blockages, and the logs, burner, and connections should be inspected for soot buildup and gas leaks. Gas burns cleaner than wood, so you won't get creosote, but you can absolutely get a blocked flue, a stuck damper, or a venting problem that pushes carbon monoxide back into the house. Gas fireplace service is a little different from a wood sweep, but the inspection discipline is the same.

We do, every time. The cap and crown are your chimney's first line of defense against Houston rain, and a cracked crown or missing cap is the main reason we see water-stained ceilings and rusted dampers in homes around the city. During the sweep, we check the cap for rust-through and blockages, and we look at the crown for cracks or spalling. If the cap needs replacing, we'll show you photos and give you a written quote. A $300 cap replacement is a lot cheaper than a $3,000 flue rebuild, and we'll tell you plainly when it can wait and when it can't.

A Level 1 inspection is a visual check of the readily accessible parts of your chimney: the firebox, damper, flue, cap, and crown. It's what we do during a standard sweep and it's right for homes that haven't changed fuel type or had problems. A Level 2 inspection adds camera scanning of the flue interior and a look inside the attic, crawl space, and other accessible areas around the chimney structure. You need a Level 2 when you're buying or selling a home, after a chimney fire, after a storm or foundation movement, or when you're converting the fireplace to a different fuel. We'll help you pick the right level for your situation.

No, but they go together. A sweep is the physical removal of creosote and soot; an inspection is the evaluation of the chimney's condition and safety. At Flint Chimney Co Houston, our standard sweep includes a Level 1 visual inspection, so you get both in one visit. If your chimney hasn't been used in years, was recently exposed to a bad storm, or you're moving into a new home in the Houston area, the camera-based Level 2 inspection is the deeper evaluation. Sweeps and inspections are both part of keeping a chimney safe, and we bundle them so you're never guessing about the condition of your flue.

We install DuraFlex stainless steel liners and Olympia Chimney products for most of our full liner replacements in Houston. For repairs where the existing liner is still structurally sound, we use HeatShield cerfractory sealant, which restores cracked clay tile liners to rated condition at a fraction of replacement cost. The brand we recommend depends on your chimney's design, fuel type, and how you use your fireplace. Every recommendation comes with camera footage and a written quote, and we'll explain why a particular material fits your situation, not just what's on the truck.

Yes. HeatShield is a cerfractory sealant applied to the inside of a cracked clay tile liner, and it's often the right repair for Houston chimneys that have minor cracking but are otherwise in good shape. It restores the liner's structural integrity and fire resistance without the cost and disruption of a full liner removal. We use it when the damage is limited and the flue size stays adequate, and we'll show you the camera footage that supports that call. When the liner is too far gone for a repair, we'll tell you straight and price you a DuraFlex stainless replacement instead.

A properly installed stainless steel liner typically lasts 20 to 30 years in the Houston area, but our humidity and the acid byproducts of wood combustion mean the grade of steel matters. We specify liners that are rated for the fuel you burn, and that choice is a big part of the lifespan. A liner that's sized right, installed without kinks or gaps, and connected properly to an insulated flue will last decades. We stand behind every liner we install, and we inspect and maintain thousands of liners across Houston every year. Your liner's condition is something we'll check at every annual visit.

Every professional working under our name is required to hold the license and insurance their state requires for the work they perform, and that standard applies to every location across the Flint Chimney Sweep family. We carry general liability coverage, and our crew works under the discipline and standards of The Garrison Code. That means we show up inside the window we gave you, put the price in writing before any work starts, do the job by the book, and leave your site clean. We're a local Houston business that agreed to work to that standard, and we're accountable for it.

Our crew members are trained to the Flint Chimney Sweep standard, which follows the National Fire Protection Association's guidelines for chimney inspection and cleaning. The training covers flue anatomy, creosote stages and removal, liner inspection, cap and crown evaluation, and the safety protocols that keep your home protected during the work. We don't send someone onto your roof or into your chimney until they've proven they can do the job by the book. When our team shows up at your Houston home, they know exactly what they're looking at and exactly what to do about it.

Yes, and that local experience matters more in Houston than most people realize. Our humidity creates dense, stubborn creosote that acts differently than the dry, flaky stuff you'd find in El Paso or Amarillo. Foundation movement in our clay soils puts stress on chimney structures and can open cracks in masonry and liners. We know the common chimney designs in neighborhoods from Katy to Pearland to Atascocita, and we know what those specific constructions tend to do over time. When we inspect a Houston chimney, we're checking for the problems we know this area produces.

The real urgency questions we get are chimney fires, water rushing in through the chimney during a storm, and gas smells coming from a fireplace. If you've had a chimney fire, stop using the fireplace and call us at (325) 750-6259. If water is actively entering your home around the chimney, shut off that area and call. Gas smells mean calling your gas utility immediately, then calling us once the leak is handled. Our phone hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. We'll get you scheduled and walk you through what to do until we arrive.

If you've heard a roar in the flue, seen flames shooting from the chimney top, or smelled an intense burning odor during a fire, stop using that fireplace immediately and call (325) 750-6259. Chimney fires can damage the flue liner, crack the masonry, and compromise the whole chimney's safety, even after the visible fire is out. We'll do a full inspection with a camera to check for damage before you use the fireplace again. Don't build another fire until we've looked at it. The damage from a chimney fire is often invisible from the ground, and the next fire can be the one that spreads into the house.

We schedule appointments by the week, not by the hour, and we'll give you a clear arrival window when you book. Most sweeps and inspections in the Houston area are booked one to two weeks out during fall and early winter, which is exactly why we recommend September and October appointments before the rush. Outside of burning season, we can usually get you scheduled within a few days. Call (325) 750-6259 during our phone hours, Monday through Friday 7:00 AM to 7:00 PM or Sunday 7:00 AM to 7:00 PM, and our coordinator will find the next available slot for your neighborhood.

Every Flint Chimney Sweep location works to The Garrison Standard: we arrive inside the window we gave you, put the price in writing before any work starts, do the job by the book, and leave the site clean. The work itself is guaranteed in writing for a full year. If anything we swept or installed fails in that year, we come back and make it right at no charge. That's the promise stamped on every job we do in Houston, and it's the same promise every independent Flint location makes across the country. You'll see it in your paperwork, and we stand behind it.

Yes. Liner repairs, cap replacements, crown work, damper service, and every other repair we perform in Houston are covered by a written one-year guarantee. If the repair fails during that year, we return and fix it at no charge. That guarantee comes from The Garrison Standard, the standard that every Flint Chimney Sweep location agrees to work under, and it applies to every job regardless of size. Keep your paperwork, and if anything doesn't hold up, call (325) 750-6259 and we'll make it right. A guarantee only matters if the company that wrote it shows up, and we show up.
