Johnson Chimney LLC provides chimney sweep services in Fairfax, including fireplace & wood stove chimney sweep, masonry chimney inspection & repair, carbon monoxide safety check, 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 Fairfax and nearby areas.
Fairfax’s older homes, especially those near the Huntley Meadows area, often have chimneys that haven’t been swept since the last owner moved out. That’s a recipe for Stage 3 creosote, which burns at 1,100°F and can ignite while you’re sleeping. Our crew uses rotary brushes and vacuum systems to pull out every trace, then checks for cracks in the liner that let carbon monoxide seep into your home. We’ll also test your draft to ensure smoke isn’t backing up into your living space. Unlike quick sweeps that miss the upper flue, we climb every inch and document our findings so you know exactly what’s been fixed. Pricing starts at $120 for a basic sweep, but we’ll waive the fee if we find a critical safety issue during your free inspection.
Call about this serviceIf your chimney’s bricks are crumbling or the mortar between them looks like sand, you’re one heavy rainstorm away from a structural failure. Fairfax’s older neighborhoods, like the ones near the Route 50 corridor, have chimneys built with softer mortar that wasn’t designed for Virginia’s humidity swings. Our inspections include a moisture test to check for hidden rot, a structural stability assessment, and a look for missing or damaged cap stones that let water pool inside. We don’t just point out problems; we provide a repair timeline and cost breakdown so you can prioritize fixes before winter. Repairs for cracked flue tiles start at $350, but sealing a leaking chimney crown can add 10 years to your chimney’s life, and prevent a $5,000 rebuild down the road.
Call about this serviceYou won’t smell carbon monoxide, but you will feel its effects: headaches, nausea, or fatigue that won’t go away. Fairfax’s gas fireplaces, especially those in homes built before 1990, often have flues that weren’t properly sealed during installation. Our CO safety check includes a portable detector test, a visual inspection of your flue connection, and a check for rust or corrosion in the venting system. If we find a leak, we’ll show you how to vent it properly, or recommend a temporary CO alarm rental while you schedule permanent repairs. This service is $95, but it’s the difference between a false alarm and a hospital visit. We’ve found leaks in 3 out of every 10 Fairfax homes we inspect.
Call about this serviceA chimney without a liner is like driving without seatbelts: it’s not illegal until it’s too late. Fairfax’s older homes often have clay liners that crack from the weight of creosote or the shifting of the house over time. Our stainless steel liners are built to handle the heat and last through decades of use, plus they reduce the risk of a chimney fire by 90%. Installation takes 1-2 days, and we’ll coordinate with your schedule to minimize disruption. The cost varies by chimney size ($1,200-$3,500), but we offer financing options and can often bundle it with your annual sweep for a discount. We’ve installed over 50 liners in Fairfax alone, and every one of our clients has called back for their next inspection.
Call about this serviceIf you burn wood more than twice a week, you’re playing Russian roulette with your chimney. Fairfax’s dry air turns soot into sticky creosote in half the time it takes in wetter climates, and that’s a fire waiting to happen. Our annual maintenance plan includes two sweeps (one before fire season, one after), a free CO safety check, and a 10% discount on any repairs. We’ll also send you a reminder before your next appointment so you don’t forget, because forgetting means risking a chimney fire. Plans start at $180/year, but the peace of mind is worth it. We’ve prevented three chimney fires in Fairfax alone by catching creosote buildup early.
Call about this serviceA chimney fire moves faster than you can grab a fire extinguisher. The flames can reach 2,000°F in minutes, melting your flue tiles and sending sparks through your roof. We keep a crew on standby for Fairfax emergencies, and we’ll arrive with a fire extinguisher, thermal imaging camera, and a plan to contain the damage before it spreads. Our response fee is waived if we’re called within 24 hours of a fire, and we’ll document the damage for your insurance claim. We’ve extinguished chimney fires in homes near the Chain Bridge Road area, and in every case, the homeowner avoided thousands in repair costs by acting fast. If you see flames or hear popping/crackling sounds, call us immediately, don’t wait for the fire to spread.
