Pricing & Cost FAQs
A standard chimney cleaning in Houston typically runs between $150 and $300, depending on the chimney's condition, height, and how long it's been since the last sweep. Fireplaces that burn a lot of green wood or haven't been cleaned in years fall on the higher end because the creosote buildup takes more time to remove properly. We give a written price before any work starts, so you'll know the exact number before our team touches anything. Call (903) 961-6496 for a free estimate.
The main factors are the amount of creosote and soot buildup, roof access difficulty, chimney height, and whether the flue has any obstructions like animal nests or fallen masonry. Houston's humidity also plays a role. Moisture mixes with creosote and makes it more acidic and stubborn to remove. A two-story home in Katy with a steep roof pitch will cost more than a single-story ranch in Pasadena simply because of the extra setup time and safety equipment involved.
No. A visual inspection of the flue is part of every cleaning we do. When our sweep is on the roof and inside the firebox, they're looking at the flue liner, mortar joints, damper, and chimney cap. If they spot something that needs attention, you'll see it for yourself because we show you the flue with our camera. That's the whole point of The Kingswell Way: the sweep that shows you the flue.
No. The price we write down before the job is the price you pay. If we find something that needs repair, we'll show it to you on camera and give you a separate written quote. You decide what gets done. No pressure, no surprise charges at the door. That's one of the four Kingswell promises: say the price before the work.
Pricing differences usually come down to what's included. Some companies quote a bare-bones sweep and then upsell a camera inspection, a cap replacement, or a creosote treatment as add-ons. We include the visual flue inspection and photo documentation in the cleaning price. The written estimate you get from us reflects the work the chimney actually needs, nothing padded.

Service & Process FAQs
We start by laying drop cloths around the firebox and setting up a HEPA-filtered vacuum before we touch the flue. Then our sweep removes creosote and soot from the flue walls with rotary brushes sized to your chimney. After that, we clean the smoke chamber and firebox, then check the damper, cap, and liner condition. You get a camera view of the cleaned flue and a photo report so you can see what we saw. The place is left cleaner than we found it.
Most standard chimney cleanings in the Houston area take between 45 minutes and two hours from setup to final cleanup. A chimney that hasn't been swept in five years or has heavy creosote glaze will take longer because the removal process is slower and more careful. If we're also replacing a chimney cap or doing minor repairs, the visit may extend. We'll give you an arrival window before we show up, and we work within it.
The National Fire Protection Association standard, which most Houston inspectors reference, is that a chimney should be swept when there's 1/8 inch or more of creosote buildup, or any time there's an obstruction. You can check the inside of the flue yourself with a flashlight: if you can scrape off a dark deposit thicker than a nickel, it's time to call. Soot dropping into the firebox after you close the damper is another sign. When you call us, we'll schedule the sweep and verify what's actually there.
If you have visible creosote buildup or you haven't had the chimney swept in more than a year, it's safer to wait. Creosote is flammable, and the heat of one good fire can ignite it. If you must use the fireplace, burn only dry hardwood, keep the fire small, and never leave it unattended. But the better advice is to schedule your cleaning now and enjoy the fire after the flue is clean.
Once a year is the standard answer, and it's the right one for most Houston homes that burn wood regularly. If you burn unseasoned wood, use your fireplace every week during the winter, or your flue tends to build up creosote quickly due to the humidity, you may need it twice a year. Chimneys that are only used a few times each season can often go 18 months between cleanings, but an annual inspection is still wise. Nathan Corliss and our Houston team will tell you honestly when you could wait.
Yes. Gas fireplaces don't produce creosote the way wood does, but they still need periodic inspection and cleaning. Gas logs can cause soot buildup, and the venting system needs to be checked for blockages that affect carbon monoxide clearance. Homes in Spring, Missouri City, and Friendswood with older gas inserts benefit from an annual check to make sure the venting is clear and the pilot assembly is clean.
Brands & Parts FAQs
We install and repair stainless steel and aluminum liners from brands like DuraFlex and Olympia Chimney. These are two of the most widely used liner systems in the U.S., and they hold up well in Houston's humid climate when installed correctly. If your existing liner is damaged, we'll show you the problem on camera and explain your options, including a HeatShield resurfacing treatment for liners that are still structurally sound but showing surface cracks.
It depends on the severity. Surface cracking and minor spalling can often be addressed with HeatShield, a cerfractory sealant that restores the liner's surface and seals small gaps. But if the liner has large cracks, collapsed sections, or the flue is too far gone, a new DuraFlex stainless liner is the right call. We never recommend liner work without first showing you the camera footage that proves it's needed. That's the Kingswell standard.
Yes, we supply and install chimney caps and dampers. A properly fitted cap keeps rain, birds, and raccoons out of your flue, and Houston's storms make a cap especially important. We install standard steel and copper caps as well as top-sealing dampers that reduce air loss through the flue when the fireplace isn't in use. The right fit depends on your flue dimensions, and we measure on site.
Yes, we can supply Gelco caps and chase covers for Houston-area homes. Gelco products are known for their durability and fit, and they're a common sight on chimneys in Katy, Richmond, and Rosenberg. If your chimney has water leaking around the flue or the chase cover is rusted, we'll spec the right Gelco replacement and install it properly.
Licensing & Insurance FAQs
Every professional working under our name is required to hold the license and insurance their state and local jurisdiction requires, and our Houston team meets those requirements. No homeowner should ever let an unlicensed, uninsured worker on their roof or inside their chimney. When you book with us, you're getting a professional crew that works to the Kingswell Guarantee and carries the coverage they're supposed to.
Our sweep team is trained on proper flue inspection, creosote removal, liner diagnostics, and chimney safety. We don't make claims about individual certifications we haven't earned, but the standards we work to come from the Kingswell Way: do the job correctly, show you the flue, and stand behind the work. Nathan Corliss leads this Houston branch with those standards front and center.
Ask for proof of insurance, check their reputation, and get the scope of work and price in writing before the job starts. If a chimney sweep quotes a very low price over the phone without asking about your chimney's age, height, or history, that price will probably change at the door. We give you a written price before any work begins and we don't change it unless you ask us to do more.
Emergency & Response FAQs
Yes, chimney leaks are a common problem in Houston's heavy rain season. Water enters through cracked crowns, missing caps, damaged flashing, or compromised brick. We'll find the exact entry point, show you the evidence, and fix it before it becomes a ceiling repair. If you see water staining on the ceiling near the fireplace, call (903) 961-6496 to schedule an inspection and leak trace.
Our Houston team is available Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM. We're closed Saturday. When you call (903) 961-6496, a live coordinator will answer and connect you with our local scheduling. We give you an arrival window and we show up inside it. No "sometime between 8 and 5" runaround.
We aim to schedule a sweep or inspection as soon as possible based on your location and our route. Houston traffic from Katy to Clear Lake and everywhere between is real, so we run routes and give you a realistic arrival window. For urgent issues like water actively leaking into the house or a strong chimney smoke odor, we do our best to prioritize you. Call (903) 961-6496 and tell the coordinator what's happening.
Stop using the fireplace immediately and open a window to ventilate the room. Smoke backup signals a flue obstruction or drafting problem, and burning any longer can push carbon monoxide into the living space. Let the fire die out and don't start another one. Then call us at (903) 961-6496. Our sweep will bring a camera and find the blockage or drafting issue, then show you exactly what's wrong.
Warranty & Guarantees FAQs
Every job we do in Houston is covered by The Kingswell Guarantee, and it's simple: a written price before any work starts, a real arrival window we actually hit, a clean job site when we leave, and a written guarantee on the work. If a repair we make fails inside the guarantee period, we come back and fix it at no charge. That's not a marketing line. It's the way this brand operates.
The guarantee period depends on the type of repair. Liner work, caps, and masonry repairs all carry a written guarantee that we give you before we start. The specific term is on your paperwork and it's backed by the Kingswell Guarantee. What matters to you is that if the repair fails inside the guarantee period, you're not fighting with anyone. You call us, we come back, we fix it. No charge.
Yes. If you still have drafting or smoke problems after our cleaning, call us back. A smoky chimney can have causes beyond creosote: a damper that doesn't open fully, a flue that's undersized for the firebox, negative air pressure from HVAC systems, or a cap that's too restrictive. We'll come back, identify the real issue, and walk you through the fix. You won't have to chase us. We come back if it fails. That's the promise.
