Too many chimney companies throw around terms like ‘Stage 2 creosote’ or ‘EFG-rated liners’ without explaining what they mean. We won’t do that.

Using high-efficiency vacuums and brushless tools, we remove all creosote, soot, and debris from your chimney. We don’t just push it down, we vacuum it out completely. During the process, we inspect every component: flue liners, dampers, smoke chambers, and even the roof flashing. If we find cracks, rust, or other damage, we’ll note it in our report. This step ensures your chimney is not only clean but also safe for use. We’ll also test for proper draft and carbon monoxide levels to confirm everything’s working as it should.
If our inspection reveals issues like a rusted damper, a collapsed flue tile, or a leaking crown, we’ll recommend the right fix, whether it’s a simple adjustment or a full relining. We use high-quality materials that match your chimney’s age and construction, ensuring repairs last through Washington’s humidity and temperature swings. Every repair comes with a written warranty, and we’ll schedule a follow-up to confirm it’s holding up. No cheap fixes here, just durable solutions that keep your chimney performing like new.
Before we leave, we’ll walk you through what we did, answer any questions, and demonstrate that your chimney’s drawing properly. We’ll also provide a written report detailing the work performed and any recommendations for future maintenance. If you’re unsure about anything, we’ll explain it again until you’re confident. Our goal is to leave you with a chimney that’s clean, safe, and ready for use, no confusion, no surprises. And if you have any issues after we’ve gone, our guarantee means we’ll come back to fix it.
"We’ve had our chimney swept a few times in Washington, but Dominguez Chimney was the first crew who actually fixed the problem. Last winter, our fireplace kept smoking no matter how hard we tried to adjust the damper. They found a crack in the flue liner near the roof and relined it in a single day. Now it pulls smoke like new, and we’ve had zero follow-up calls since the job. Their workmanship is top-notch, and they even cleaned up better than when they arrived. Highly recommend for anyone in DC who wants real expertise."
"I was skeptical about hiring a chimney sweep after reading horror stories about ‘fly-by’ crews, but Dominguez Chimney changed my mind. They showed up on time, explained exactly what they were doing, and didn’t try to sell me on unnecessary repairs. When they found a nest of squirrels in my chimney, they removed them humanely and sealed the entry points so they won’t come back. The best part? They vacuumed out every last bit of debris, no soot on my floors or in my fireplace. That level of cleanliness is rare in this city."
"After moving into our condo near the Wharf, we lit the fireplace once and immediately had smoke filling the room. The previous owners swore it was fine, but Dominguez Chimney found a collapsed section of the flue tiles and a rusted damper. They repaired both and even upgraded the damper to a stainless steel model that won’t corrode in DC’s humidity. Now our fireplace works like a dream, and we’ve had zero issues. Their attention to detail is what sets them apart from the other chimney guys in the area."
"We’ve used Dominguez Chimney for years, and they’re the only crew we trust with our historic row house. They know our chimney’s quirks, like how it gets clogged with creosote faster than others because of our old brick construction, and they always address the root cause. Last time, they found a small crack in the smoke chamber and sealed it with high-temp mortar. They even took the time to explain why it happened (a leaky roof flashing) and how to prevent it. That’s the kind of service you don’t find everywhere in DC."
"I was dreading the idea of having my chimney swept after reading about how messy it can be, but Dominguez Chimney made the whole process stress-free. They showed up on a Saturday morning, worked efficiently, and left the area spotless, no soot on the floor, no debris in the fireplace. They also found a blockage from leaves that had blown in through a loose cap and cleaned it out completely. The best part? They gave us a maintenance plan so we don’t have to worry about this again for a year. Worth every penny."
"I’ve had chimneys swept in other parts of the city, but none of them compared to Dominguez Chimney. They didn’t just sweep, they inspected every inch, including the roof flashing and the chimney cap, and found a few issues I didn’t even know existed. They fixed them on the spot and explained why they mattered. Their crew was professional, respectful of our property, and took the time to answer all my questions. If you want a chimney sweep that actually cares about the work, this is the team to call in Washington."

Proudly serving Washington and these nearby communities.
That chemical smell means creosote, tar-like residue from burning wood, is breaking down in your chimney. Washington’s damp air speeds up this process, turning creosote into a sticky, flammable goo that can ignite. If you notice a strong, acrid odor when lighting up, your chimney needs a sweep now. Ignoring it risks a chimney fire, especially during winter when you rely on your fireplace most. We use brushes and vacuums designed to remove all stages of creosote safely.
Birds love nesting in chimneys because they’re warm and sheltered. Signs include feathers, droppings, or a musty smell when you open the damper. If you see twigs or hear chirping, that’s a clear warning. Birds block airflow, trap soot, and create fire hazards. We remove nests humanely and inspect for damage to the flue lining. Washington’s older brick homes are prime targets, don’t wait until you smell ammonia or see stains on your ceiling.
No, that’s not normal. Washington’s freeze-thaw cycles weaken mortar over time, but active crumbling means water’s getting in through cracks or missing flashing. If you spot loose bricks, white mineral deposits, or damp patches on your ceiling, your chimney needs repointing or a waterproof sealant. If left alone, that leads to structural rot and expensive fixes down the road. We’ll assess the integrity of your masonry and recommend fixes before winter makes it worse.
Yes, but only if the sweep confirms no obstructions, cracks, or excessive creosote buildup. A ‘clean’ chimney means it’s safe for one burn cycle, but we’ll note any minor issues that need monitoring. In Washington, where fireplaces are critical for heating, we always test draft and carbon monoxide levels before you light up. If we find even a small problem, we’ll hold off until it’s resolved. Your safety isn’t worth the risk of a single fire.
Wind creates pressure differences that push or pull air through your chimney. If your fireplace smokes more on gusty days near the Mall, your chimney might be too tall, have a weak draft, or need a larger flue. We check for blockages, damper issues, or improper sizing during inspections. A well-sealed chimney should draft consistently regardless of weather. If it doesn’t, we’ll adjust the damper or recommend upgrades to keep your home warm efficiently.
White powder is usually mineral deposits from water evaporation, common in Washington’s humid summers. But if it’s accompanied by rust stains or a metallic smell, your chimney cap or liner may be corroding. This happens when moisture seeps in through gaps or a damaged cap. We’ll inspect for active corrosion and seal any leaks before they damage your masonry. Never ignore this; rust weakens structural supports over time.
Look for sagging masonry, large cracks wider than 1/8 inch, or bricks that pull away from the structure. If your chimney leans or has missing mortar joints over 20% of its height, it’s past repair and needs a full rebuild. Washington’s historic homes often hide these issues behind decorative brickwork. We’ll assess stability and recommend the safest course, sometimes that means tearing out damaged sections and rebuilding with modern materials that last.
Yes, if your chimney isn’t venting properly, backdrafting can blow out the pilot light. Wind, obstructions, or a blocked flue create negative pressure that disrupts combustion. We’ll check for creosote buildup, bird nests, or a damaged liner that’s restricting airflow. In Washington’s coastal areas, humidity also causes condensation in gas lines, which we’ll clean out. A simple sweep often fixes the problem, but if the issue persists, we’ll inspect the entire venting system.
