We’re a local team with deep roots in Concord, not a franchise pushing upsells. Our pricing is transparent—no bait-and-switch estimates or surprise charges. You’ll get a detailed breakdown before we start, so you can see exactly what you’re paying for. Plus, we’re licensed, insured, and backed by a 10-year warranty on all work. When your chimney’s done, it’s done right.
Creosote buildup in your flue isn’t just dirty—it’s a fire hazard. In Concord’s older homes, where chimneys often predate modern codes, the risk is even higher. A neglected chimney can lead to chimney fires, carbon monoxide leaks, or blocked drafts that force smoke back into your home. The average repair for water damage from a leaky chimney? Over $3,000. A sweep now costs a fraction of that.
Big sweepers profit from fear—telling you every little flaw needs ‘immediate attention.’ We focus on what’s truly urgent. If your chimney just needs a sweep, that’s all you’ll pay for. No pressure to upgrade liners, add crowns, or buy unnecessary inspections. Our goal is a safe chimney, not a maximized invoice. It’s how we’ve earned Concord’s trust for years.
Concord’s humid summers, freeze-thaw winters, and sudden temperature swings accelerate chimney wear. Brick absorbs moisture, then expands when it freezes, cracking mortar over time. Our repairs use materials rated for New England’s climate, so your chimney weathers every season without fail. Think of it as an investment in avoiding a $10,000 rebuild down the road.

Our crew arrives on time, works efficiently, and leaves your home spotless, because we know your time and budget matter more than empty upsells. We’re the local choice for homeowners who want expert care without the premium markup.
"Aster Chimney Co. swept my chimney last month, and I was blown away by their honesty. They told me my chimney just needed a cleaning—not the $2,000 liner they said I ‘needed’ elsewhere. Saved me a ton of money and stress."
"After a chimney fire scare, I called Aster for an inspection. They found minor cracks but no immediate danger—no upsell, just the facts. Their repair work has held up through two harsh Concord winters."
"My 1800s Concord home’s chimney was a mess. Aster repointed the mortar and installed a cap—no nonsense, no extras. The crew was on time, cleaned up perfectly, and even helped me spot a draft issue I didn’t know about."
"I’ve used big-name sweepers before, but Aster was different. They showed me creosote buildup in real time with their camera, then gave me a fair quote. No pressure, just great service. Highly recommend."
"We had a leaky chimney crown causing water damage in our kitchen. Aster replaced it with a custom solution that’s held up perfectly. Their warranty gave me peace of mind—something the other guys wouldn’t even offer."
"My pellet stove vent was filthy, and Aster cleaned it thoroughly. They also checked my stove’s clearances to code—something no one else bothered with. Professional, thorough, and worth every penny."

That campfire odor is likely creosote buildup or trapped moisture, both common in older Concord homes with masonry chimneys. We’ll inspect your flue for trapped water (thanks to our damp springs) and remove any creosote deposits that act like a sponge. A thorough cleaning and a waterproofing treatment can eliminate the smell for good—often in under an hour.
Water intrusion in Concord is usually from cracked masonry, missing crowns, or deteriorated flashing—all common in our freeze-thaw climate. We’ll seal cracks with high-temperature mortar, replace damaged crowns, and ensure your flashing is watertight. Fixing this now prevents costly rot and mold, saving you thousands down the road.
Yes, most Concord realtors recommend a Level 2 inspection for home sales, as it includes a video scan of your flue and identifies hidden hazards like cracks or blockages. It’s a small cost compared to a deal falling through or a buyer demanding repairs after closing. We provide same-day reports for your agent.
A 20-year-old liner in Concord’s climate is likely past its prime, especially if you use your fireplace often. We’ll inspect it for cracks or deterioration; if it’s compromised, replacing it now avoids carbon monoxide leaks or chimney fires. Our team can install a stainless-steel liner in a single visit.
Pine burns hot and fast, creating excess creosote that coats your flue—especially risky in Concord’s older chimneys. We recommend seasoned hardwoods like oak or maple, which burn cleaner and produce less residue. If you love pine, use it sparingly and schedule an extra cleaning before winter.
Beware of Concord chimney sweeps promising “premium” services at inflated prices—like unnecessary inspections or upsold repairs. We charge $300 for a standard cleaning because it’s what it costs: certified techs, proper equipment, and no hidden add-ons. Always ask for a written estimate before work begins.
A drafty flue after cleaning usually means your damper isn’t sealing properly or your chimney cap is missing. We’ll check both during your appointment and adjust the damper for a tight seal. A $20 part can save you $200 in heat loss this winter.
For most Concord homeowners, once a year is enough unless you burn over 3 cords of wood annually. Heavy use or burning unseasoned wood may require an extra cleaning, but we’ll assess your habits during our visit. Over-sweeping is a common upsell—don’t pay for it unless you need it.
