What's included

Here's exactly what we do.

Every fire leaves behind creosote — a flammable residue that coats the flue and, left alone, becomes the fuel for a chimney fire. Add nesting debris and blockages, and a fireplace can start pushing smoke back into the room. A proper sweep clears the buildup and gives you a clear picture of the flue's condition before the cold sets in.

  1. 1

    Inspect the flue & firebox

    We check the flue, damper, and firebox for creosote level, blockages, and obvious damage before we start sweeping.

  2. 2

    Contain the work area

    We protect the hearth and surrounding room and use vacuum containment so soot stays out of your living space.

  3. 3

    Sweep the flue thoroughly

    Brushes sized to your flue scrub creosote and soot from the full length of the liner.

  4. 4

    Clear blockages & debris

    Nests, leaves, and debris that block draft or invite backdraft are removed from the flue and smoke chamber.

  5. 5

    Report what we find

    You get a clear rundown of the flue's condition and any safety concerns — no upsell, just what you should know.

Signs you need this

If any of these sound familiar, let's talk.

  • It's been a full season (or more) since your last sweep
  • Smoke pushes back into the room when you light a fire
  • A strong, tarry smell from the fireplace, especially when damp
  • Black, flaky, or glossy creosote visible in the firebox or flue
  • Animals, nests, or debris getting into the chimney
  • You just bought the home and don't know its service history

The full-lifecycle difference

Most companies stop at the clean. We don't.

Chimney Cleaning is one piece of the picture. Because we own the whole lifecycle — clean, repair, re-route, install, and fan replacement — we can actually solve the problem instead of handing you a bill and a referral.

Chimney repairs are quoted from the inspection — and we offer a free second opinion anywhere in Northern Virginia.

  • Level of creosote buildup

    Light seasonal soot sweeps quickly; heavy or glazed creosote takes more work and specialized methods to remove safely.

  • Chimney height & access

    Taller flues and steep or high roofs require more setup and safe access than a low, easily reached chimney.

  • Flue type & condition

    The liner type and any blockages or damage we find affect how involved the sweep is.

  • Inspection depth

    A standard sweep-and-inspect is the baseline; a more detailed camera inspection is optional and quoted separately.

Chimney Cleaning FAQ

Questions homeowners actually ask.

  • For regular wood-burning fireplaces, once a year before the burning season is the standard. Heavy use or signs of buildup mean it's worth doing sooner.

  • Creosote is the flammable residue left behind when wood burns. As it builds up inside the flue it becomes fuel for a chimney fire, which is exactly why regular sweeping matters.

  • That usually means a blocked flue, heavy creosote, or a draft problem. A sweep clears blockages and buildup so the chimney drafts smoke up and out the way it should.

  • No. We protect the hearth and room and use vacuum containment so soot is captured rather than spread across your floors and furniture.

  • Yes. Every sweep includes a look at the flue, damper, and firebox condition, and we tell you plainly about any safety concerns we spot.

  • Ideally, yes. Getting it done before the cold season means your fireplace is safe and ready when you actually want to use it, instead of waiting on a busy peak-season schedule.

Case study

Recent Work in Alexandria: Chimney Liner & Smoke Chamber Repair

A homeowner in Alexandria asked us to inspect their chimney before relying on the fireplace. We ran a Level 2 inspection — the detailed evaluation that runs a camera down the flue — and it surfaced several problems. The clay flue had multiple cracks, and because the home was built in the 1970s, its smoke chamber predated modern standards: rough, unlined masonry that today's code no longer allows.

What we did: we installed a new stainless steel liner down the full flue and parged the smoke chamber — coating its inner walls smooth with high-temperature refractory mortar. That's what current NFPA 211 and IRC standards call for: a smooth, sealed smoke chamber and a sound liner, so combustion gases exit cleanly and heat can't reach the surrounding structure through cracks.

For this job, the liner installation was $2,950 and the smoke chamber parging was $1,599. Chimney repairs are always priced after a Level 2 inspection, since every chimney's condition is different — but this gives a real sense of what a full liner-and-smoke-chamber restoration involves.

The result: a safe, code-compliant chimney the homeowner can use with confidence.
