Most homeowners in Barnesville assume their chimney is safe if it’s been swept once a year. But what they don’t know is that creosote buildup, cracked flues, or even a poorly sealed damper can turn your fireplace into a silent fire hazard, or worse, a carbon monoxide trap. At Nathan and Patrick Chimney Inc, we don’t just clean chimneys. We hunt down the risks you can’t see, from the attic vents near your roof to the hidden gaps where cold air leaks into your home. If you’ve ever wondered why your fireplace smokes more than it burns, or if your family’s safety is truly protected, we’ll find out, and fix it. No guesswork. Just peace of mind.

"We’ve had our chimney swept before, but Nathan and Patrick actually inspected it, and found a crack in the flue we never would’ve known about. They sealed it and installed a new cap for us, and now our fireplace burns cleaner than ever. The best part? We break down chimney issues in plain language, no confusing industry terms. We’d never go back to anyone else."
"After our last sweep, we noticed smoke coming into the house when we lit the fire. Called Nathan and Patrick the same day, they were there within hours. Turns out, our damper wasn’t sealing right. They fixed it, and now our fireplace works perfectly. No more coughing through smoky fires. They’re the only chimney guys who actually care about safety, not just the sale."
"We’ve lived in our home for 20 years, and no one ever told us our chimney needed a liner. Patrick explained it simply: ‘Your old bricks are letting carbon monoxide into your house.’ Scared us straight. They installed a stainless-steel liner the next week, and now we sleep better at night. Worth every penny, and then some."
"We thought our chimney was fine until Nathan found a nest of squirrels up there. Not only did they remove the nest, but they also checked for damage and sealed the gaps where the critters got in. They even gave us tips on keeping animals out of our chimney next time. Professional, thorough, and honest. That’s hard to find in any trade."
"After a chimney fire last winter, we were terrified to use our fireplace again. Patrick came out, inspected everything, and assured us it was safe, after fixing a few small issues. He even showed us how to burn wood properly to prevent future fires. Now we use our fireplace without worry. They’re the only ones who treat chimney safety like it’s life or death, and it is."
"We’d had our chimney swept once before, but it was a quick job and the guy didn’t even check the flue. Nathan and Patrick took their time, used a camera to inspect the inside, and found a buildup of creosote that could’ve caused a fire. They cleaned it thoroughly and explained why it happened. Now we know to get it swept twice a year. Can’t recommend them enough, especially if you want real safety, not just a surface clean."
Nathan and Patrick Chimney Inc has been serving Barnesville homeowners for years, specializing in chimney safety and fire prevention. Many homeowners assume their chimney is fine if it looks clean from the outside, but hidden dangers like creosote buildup or cracked flue liners can turn a cozy fireplace into a fire hazard. We don’t just sweep, we inspect for these risks, ensuring your chimney meets Maryland’s strict safety codes before winter hits. Our team knows Barnesville’s older homes often have unique chimney designs, and we’ve seen firsthand how small issues can lead to carbon monoxide leaks or chimney fires. That’s why we focus on thorough inspections, not just quick sweeps.

We start with a no-obligation inspection to spot obvious risks, like heavy creosote, damaged caps, or animal nests. If your chimney has signs of water damage or rust, we’ll note it and explain why it matters. This step is free because we want you to know if your chimney is truly safe before you commit to anything. Many homeowners in Barnesville skip this and end up paying for repairs they didn’t realize were needed. We’ll also check your carbon monoxide detector’s placement, since a chimney leak can make even a working alarm useless.
Using motorized brushes and a vacuum, we remove all creosote and soot, then inspect every inch of your flue with a borescope camera. We look for cracks, corrosion, and gaps that could let carbon monoxide into your home. If your chimney is lined with clay tiles, we’ll test for cracks that could fail during your next fire. This isn’t just a sweep, it’s a full safety audit. In Barnesville’s older homes, we often find issues like missing spark arrestors or improper chimney heights that violate Maryland’s building codes.
If we find problems, like crumbling mortar, a rusted damper, or a blocked cap, we’ll give you a clear plan to fix them. We never upsell; we only recommend what’s necessary to make your chimney safe. For example, if your chimney cap is missing, we’ll explain why installing one could save you money on firewood by improving draft. We also check for signs of water damage, which is common in Barnesville’s rainy springs, and recommend sealants or repointing if needed. Every repair we suggest is backed by Maryland’s safety standards.
After repairs, we’ll walk you through how to use your fireplace safely, like how to burn wood properly to reduce creosote. We provide a written report with photos of any issues we fixed, so you have proof for your records. Our work comes with a warranty, and we offer a free recheck within 30 days to ensure everything’s holding up. If you’re unsure about any part of the process, we’ll answer your questions until you’re confident. Your chimney’s safety is our top priority, not just another job on our list.
What you can’t see is what kills. Creosote buildup, cracked flue tiles, and corroded dampers hide behind soot and mortar, until they don’t. In Barnesville’s older homes, many chimneys were built without modern safety liners, making them prime candidates for silent failures. We use cameras and pressure tests to find these hidden dangers before they turn into fires or carbon monoxide leaks. Your chimney might look fine from the outside, but if it’s been more than a year since your last sweep, you’re gambling with your family’s safety.
Seasonal use doesn’t mean seasonal risk. Even a few fires in cold months can leave enough creosote to ignite during a hot summer draft, or when you least expect it. Barnesville’s humidity turns creosote sticky fast, and a single overlooked sweep can mean a buildup that’s ready to burn. We see chimneys with dangerous levels of tar after just a handful of fires because homeowners assume ‘out of sight, out of mind.’ Don’t wait for a fire to realize your chimney needs attention. A quick inspection now could prevent a $10,000 repair later.
Some sweep chimneys. We hunt for hazards. A basic sweep might clear the obvious creosote, but it won’t catch the rusted damper, the cracked liner, or the mortar crumbling from years of rain. In Maryland, chimney inspections are required before selling a home, but many sellers cut corners to save time. We follow the National Fire Protection Association’s strict Level 2 protocol, including camera inspections and carbon monoxide testing, because we know what most sweeps miss. If your last chimney service didn’t include a full flue inspection, you’re paying for a partial job, and risking your home’s safety.
DIY sweeps are like changing your own oil, you might get the job done, but you’re likely to miss the critical parts. Barnesville’s chimneys often have tight bends, rusted joints, or hidden obstructions that a homeowner’s brush can’t reach. Worse, improper sweeping can damage your flue or spread creosote deeper into the chimney. We use motorized tools and vacuum systems to pull out every trace of buildup, plus we check for issues like improper chimney height or blocked caps that a DIY sweep would never notice. If you’ve ever coughed through a smoky fire or noticed soot on your ceiling, your chimney needs professional attention, not a weekend project.
Expert local advice for Barnesville homeowners.
Proudly serving Barnesville and these nearby communities.
Most chimney sweeps in Barnesville charge between $120 and $200 for a basic sweep, but prices jump if your chimney has heavy creosote buildup or needs repairs. The key is to ask if they include a full inspection with their sweep, some cut corners by skipping this step. We charge a flat rate for our inspection and sweep combo, and we’ll never upsell you for minor issues. If a quote seems too low, it might mean they’re not checking for hidden dangers like cracked liners or blocked flues, which are common in older homes near the Patuxent River area.
If you haven’t swept your chimney in over a year, it’s not safe to use it yet. Maryland’s dry winters and high humidity in summer create the perfect conditions for creosote to harden into a flammable tar. We’ve seen chimneys in Barnesville spark fires just from lighting a small fire with thick buildup. Schedule a sweep before your first fire this season, and we’ll check for any damage from last year’s use. Never assume ‘it looks fine’, creosote hides deep in the flue, and one missed sweep can turn dangerous.
Carbon monoxide leaks from chimneys are silent killers, and older homes in Barnesville are especially vulnerable because many have unlined or deteriorating flues. Signs of a problem include soot around the fireplace, yellow flames instead of blue, or headaches when the fire is lit. We test for CO risks during every inspection using handheld detectors. If your home has a wood stove or you’ve noticed draft issues, schedule a check, we’ve found leaks in homes near the Barnesville town center that homeowners never suspected.
Yes, even if your chimney was swept recently, an inspection is critical. Sweeping removes creosote, but it doesn’t catch structural issues like cracked liners or animal nests that can trap smoke and gases. In Barnesville, where homes often have masonry chimneys, small cracks can let carbon monoxide into your living space. We recommend an annual inspection, especially if you’ve had heavy use or noticed smoke spilling into the room. It’s the only way to confirm your chimney is safe for another winter.
Rotary brushes can damage older chimneys, especially those with delicate masonry or unlined flues common in Barnesville’s historic homes. The high-speed spinning can scratch liners or dislodge mortar, creating new entry points for smoke and gases. We use only push brooms and high-pressure air systems to avoid harming your chimney. If your sweep mentions rotary tools, ask how they’ll protect your flue, some older chimneys near the Patuxent River have already suffered from this method.
Wood stoves burn hotter and produce more creosote than fireplaces, so they need sweeps every 30 to 50 hours of use, or at least twice a year if you rely on them for heat. We’ve seen stoves in Barnesville develop dangerous buildup in just a few months of heavy use. Schedule a sweep before the cold season hits, and we’ll check for proper clearance and stove pipe connections, which are often overlooked. A blocked or poorly connected stove pipe can fill your home with carbon monoxide faster than you’d notice.
Brick chimneys can hide serious issues behind their sturdy exterior. Cracks, spalling (flaking) mortar, or even water damage from Barnesville’s rainy seasons can weaken the structure over time. We’ve found chimneys near the town center that looked fine from the outside but had internal cracks letting smoke into attics. After sweeping, we always inspect for these hidden problems. If your chimney is over 20 years old, it’s especially important, many Barnesville homes have original chimneys that haven’t been reinforced.
Gas fireplaces still need inspections because their vent systems can develop blockages, rust, or even animal nests that trap exhaust gases. We’ve seen gas fireplaces in Barnesville homes near the river area back up completely, filling living rooms with carbon monoxide. Even if you don’t burn wood, schedule an annual inspection to check for corrosion in the vent pipe and ensure the draft is working properly. A blocked vent is just as dangerous as a dirty wood-burning chimney.
