Oliver and Nathan Chimney LLC provides chimney sweep services in Herndon, including creosote removal & chimney sweeping, chimney inspection & damage assessment, chimney repair & waterproofing, and more. Every job is handled by licensed, insured technicians with upfront written pricing, and backed by a workmanship guarantee, with free estimates for all of Herndon and nearby areas.
Herndon’s shifting seasons, hot, damp summers and dry, cold winters, turn chimneys into creosote traps. What starts as a thin, flaky layer can turn into a thick, tar-like substance in as little as a few months if you’re not careful. That’s not just a mess, it’s a fire hazard. Our crew uses motorized rotary brushes and high-powered vacuums to break down and remove every trace of creosote, even in tight or hard-to-reach flues. We don’t just sweep; we inspect for hidden cracks or corrosion that could let moisture in, which is just as dangerous. After we’re done, your chimney will draft better, your fires will burn hotter, and you’ll sleep easier knowing there’s no hidden tinder waiting to ignite. And because we’re local, we know the telltale signs of Herndon’s specific climate-related wear, like the way our wet springs can accelerate mortar deterioration.
Call about this serviceMost chimney inspections in Herndon stop at a quick glance from the top. Ours don’t. We use a high-definition chimney camera to inspect the flue lining, smoke chamber, and even the crown for cracks you can’t spot from the outside. Why? Because a small crack in your chimney cap can let in rain, which then seeps into the masonry and freezes in our cold winters, causing spalling and further damage. We’ve seen chimneys in Herndon’s older homes with mortar joints crumbling from years of moisture, until we caught it early. Our inspections include a written report with photos, so you know exactly what needs attention and why. We’ll also check your carbon monoxide levels to ensure your fireplace is venting properly, which is especially critical if you’ve noticed soot stains on your ceiling or walls.
Call about this serviceMoisture is the hidden threat lurking in every chimney near Herndon’s neighborhoods. Whether it’s rain seeping through a cracked crown or snow melting into a rusted damper, moisture leads to rust, mold, and structural weakness. Our repairs go beyond patching, we replace corroded flashing, repoint crumbling mortar with heat-resistant sealant, and install stainless steel chimney caps that won’t warp like aluminum ones do in our humidity. We’ve fixed chimneys in homes near the Potomac River where salt spray accelerates corrosion, and in older brick homes where the original mortar just wasn’t up to modern standards. After we waterproof your chimney, you won’t have to worry about leaks ruining your fireplace or damaging your home’s interior. And because we use premium materials, our repairs hold up longer than the cheap fixes competitors might offer.
Call about this serviceIf your fireplace feels like it’s struggling to stay lit or you’re seeing excessive smoke in your living room, the lining might be worn out. Chimney relining isn’t just for old homes, it’s a smart upgrade for any fireplace in Herndon that’s seen heavy use. We install new clay flue liners or stainless steel liners, depending on your chimney’s condition, to improve draft and reduce creosote buildup. Our relining process also includes sealing gaps that let heat escape, which means your fires burn hotter and last longer. We’ve relined fireplaces in everything from historic brick homes in downtown Herndon to modern builds near the Dulles Greenway, and the feedback is always the same: ‘Why didn’t I do this sooner?’ It’s not just about fixing what’s broken, it’s about making your fireplace work better than it ever has.
Call about this servicePellet stoves and wood stoves are a great way to heat your Herndon home, but they’re also high-maintenance if you don’t keep up with servicing. A clogged pellet stove pipe can create carbon monoxide risks, while a wood stove with a dirty flue will lose efficiency and fill your home with smoke. We clean the burn pot, inspect the gaskets, and check the exhaust system to ensure your stove is running safely and efficiently. We’ve serviced stoves in homes where the previous owner skipped maintenance, leading to soot buildup that required a full reline, something we avoid by catching issues early. Our servicing includes a performance test to make sure your stove is pulling air correctly, which is especially important if you’ve noticed your stove taking longer to heat up or struggling to stay lit.
Call about this serviceCarbon monoxide has no smell, no color, and no warning, but it’s entirely avoidable with the right care. If your chimney isn’t venting correctly, CO can back up into your home, especially in tightly sealed Herndon homes with modern HVAC systems. We use portable CO detectors to test your chimney’s output after every sweep and inspection. We’ve found dangerous levels in homes where the damper was stuck or the flue was partially blocked by creosote. Our safety checks also include verifying that your chimney’s height and clearance meet local building codes, which is critical if you’ve recently added an extension to your home or upgraded your fireplace. Peace of mind isn’t just a tagline for us, it’s what we deliver with every visit.
