Washington’s old brick chimneys and modern high-efficiency inserts both need a deep clean, but they don’t take the same approach. Our crew starts with a thorough inspection to spot cracks, rust, or blockages before we sweep. We don’t just push creosote down into your flue, we vacuum it out completely, so your chimney stays clean from top to bottom. If we find Stage 3 tar (the kind that can ignite and start a house fire), we’ll recommend the right treatment to break it down safely. Every sweep includes a post-service check to ensure your chimney’s drawing properly. No half-measures. Just the kind of work that keeps your home safe during heating season.
Call about this serviceAfter a heavy rain or snowstorm, Washington homeowners often assume their chimney is fine, until they smell gas or see smoke spilling into the room. Our inspections go beyond the obvious. We check for cracked flue liners (common in older Georgetown row houses), rusted damper mechanisms, and even animal nests in unused chimneys. If your chimney has a stainless steel liner, we test for proper clearance and seal integrity. We’ll also look for signs of water intrusion, which can rot wood framing or corrode metal parts over time. Unlike quick drive-by inspections, we take our time, sometimes climbing onto roofs in nearby neighborhoods like Cleveland Park or Foggy Bottom to get a full view. You’ll leave knowing exactly what’s wrong and what needs fixing, with no upselling.
Call about this serviceA chimney that’s leaking or pulling poorly isn’t just annoying, it’s a fire hazard. If your damper sticks, your flue tiles are crumbling, or your stainless steel liner has gaps, we don’t just patch it. We replace it. Our crew uses 304-grade stainless steel liners for modern inserts and high-temperature ceramic tiles for older masonry chimneys, both rated for Washington’s humidity and cold snaps. We’ve repaired chimneys in historic Capitol Hill townhouses and new condos near the Wharf, always using the right materials for your home’s age and construction. No cheap duct tape fixes here. Every repair comes with a written warranty and a follow-up to ensure it’s holding up. If your chimney’s been giving you trouble for years, let’s talk, we’ll make it right.
Call about this serviceWashington homeowners who use their fireplaces regularly know the drill: you light it up after a long winter, and suddenly you’re coughing through smoke because the chimney’s clogged. Our maintenance plans stop that from happening. We’ll sweep your chimney twice a year (fall and spring), inspect critical components, and even clean your fireplace glass so it stays crystal clear. For homes with wood-burning stoves, we include a stove pipe inspection to catch rust or gaps before they cause carbon monoxide leaks. Plans start at $199/year and include 20% off repairs if we find issues during your checkups. No contracts, no surprises, just peace of mind that your chimney’s ready when you are. Perfect for renters, vacation homes, or anyone who wants to avoid last-minute holiday rush fees.
Call about this serviceA chimney that’s not drawing right isn’t just inefficient, it’s pumping carbon monoxide into your home. Our smoke and CO testing uses specialized tools to pinpoint exactly where the problem is: a blocked flue, a cracked liner, or even a poorly installed damper. We’ve tested chimneys in row houses near the National Mall and modern lofts in Navy Yard, and the fixes aren’t always what homeowners expect. Sometimes it’s as simple as adjusting the damper or cleaning out debris. Other times, it’s a relining job or sealing gaps in the masonry. We’ll never tell you to “just use your fan” or “light a bigger fire”, those are band-aids. Our goal is to make your chimney work right, so you can enjoy your fireplace without worrying. And if we find a serious issue, we’ll explain it in plain terms, not industry jargon.
Call about this serviceWashington’s urban wildlife knows a good chimney is a cozy hideout. By the time you notice droppings in your fireplace or a foul smell, that animal’s already caused hundreds in damage. Our crew uses humane traps and one-way exclusion devices to remove critters without harming them, then we clean out nests, repair chewed liners, and seal entry points with stainless steel mesh. We’ve dealt with everything from persistent raccoons in Capitol Hill to swallows nesting in flues near the Waterfront. The key is acting fast, once an animal gets comfortable, they’ll keep coming back. We’ll also check for signs of future intrusions, like loose bricks or gaps in your crown. No more guessing when your first winter fire lights up without a hitch.
