Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes solid products. But every manufacturer has known weak points, and after years of camera inspections in Manassas homes, we’ve learned exactly where DuraFlex systems show stress. Here’s what we see most often:
- DuraFlex stainless rigid liner seam separation. The single-wall rigid liner sections can pull apart at the seams when the flue runs through an offset or when chimney settling shifts the structure. On camera, the seam gap is visible as a dark horizontal line with light bleeding through from behind. We fix it by reseating and mechanically fastening the affected section, or by replacing the run if the metal has thinned.
- DuraFlex flexible liner pinholes from acidic condensate. Gas fireplace exhaust carries moisture. Flex liners that weren’t sized correctly or that run through an uninsulated chase can develop pinhole corrosion within eight to twelve years. You’ll notice a sulfur smell near the fireplace or rust staining on the cap. The camera confirms it. The fix is a new flex liner, properly insulated this time.
- DuraFlex Direct Vent pipe gasket failure. The gaskets at the appliance connection and wall pass-through dry out and crack, especially in Manassas attics where summer heat fluctuates. The symptom is a faint exhaust odor in the house that comes and goes. We replace the gasket set and test the joints under pressure before we leave.
- DuraFlex insert surround air leaks. The sheet-metal surround on DuraFlex inserts relies on a tight fit to the firebox opening. Over years of thermal cycling, the surround warps slightly and outside air infiltrates, which makes the fireplace burn inefficiently and can set off carbon monoxide detectors. We shim, seal, and verify the draft with a smoke test.
- DuraFlex terminations and caps loosening. The caps on DuraFlex vent terminations are held by a twist-lock that can back off in high wind. Manassas gets enough nor’easter remnants that we see this a few times each fall. The cap rattles or the pilot won’t stay lit. We resecure with a set screw and verify the termination mesh is clear.
Our DuraFlex Fireplace Services Process
Every DuraFlex job in Manassas follows the same sequence. No exceptions, no shortcuts.
- 1
You call (571) 946-2300. A live person answers, asks what you’re seeing, and books a window that works for you. You get a text when the technician is on the way, with their name and photo.

Camera inspection first. We run a camera down the flue before offering any repair opinion. NFPA 211 Level 2 inspection, photo record included. Clause 4 of the Haven Standard requires it on every job, and we’ve done it that way since 2009.
- 3
Written scope and price. Corrine reviews the footage and writes down exactly what was found, what needs to happen, and what it costs. Parts options are stated plainly: OEM DuraFlex or approved aftermarket, with the price difference in writing.
- 4
Repair or replacement with documentation. We complete the work, then run the camera again so you can see the fix yourself. Photos before, photos after, and a written warranty for every part and labor hour.
- 5
Test and clean up. We verify draft with a smoke or pressure test, sweep the work area, and walk the entire fireplace with you.
- 6
365-Day Done Right Promise. If anything about the repair isn’t right within a year, we make it right. No re-quote, no debate.

Why Manassas Homeowners Call Level Two Chimney Manassas for DuraFlex Work
Most chimney companies can put a flashlight up a flue. Very few run a camera down a DuraFlex liner and show you what they found before quoting a price. We’ve inspected and cleaned more than 38,000 chimneys since 2009, and every one of those jobs ended with a written price before work started and a documented photo record when it was done.
Our technicians know DuraFlex specifics: which liner seams fail, which gaskets dry out, which caps back off. But we’re not married to one brand. When a DuraFlex part is backordered or overpriced, we tell you and offer HeatShield or Gelco alternatives with the same warranty standard. We’d rather lose a parts sale than install something we wouldn’t put in our own homes.
Corrine Halstead grew up in Queens, learned the trade through a vocational program at Queensborough Community College, and has been running camera inspections on Manassas-area chimneys for over two decades. Her habit of writing findings down before quoting a price is how this company works. The camera already told her. She’s just writing it down for you.
Free second opinion on any written estimate from another company. Bring it. We’ll camera-inspect and tell you what’s real and what isn’t.
FAQs
No. Using an independent service provider does not void the DuraFlex warranty, and we install only parts that meet or exceed the original specifications. The warranty remains intact as long as the repair is done correctly and documented, which is exactly what our photo record provides.
We carry the most common DuraFlex gaskets, caps, and fasteners on our trucks, so most repairs in Manassas are completed same-visit. Odd liner sizes or specialty vent runs take three to five business days. We’ll tell you which before you commit to anything.
If the firebox, heat exchanger, and venting are intact, repair is almost always the better value. A DuraFlex fireplace with a good box and liner will run for another twenty years with routine service. The moment the liner has pinholes or the firebox is warped beyond spec, replacement becomes cheaper than repeated patch work. We’ll show you the camera footage so you can decide based on what you see, not what we say.
Every year for gas, and twice a year for wood-burning if you’re using it as primary heat. The Manassas practice of burning from October to March builds creosote fast in wood units, and gas units need a combustion check to confirm the burners and venting are clean. Annual service takes about an hour and costs less than most people expect.
For gas fireplaces, you risk carbon monoxide leakage from cracked gaskets or blocked venting, and the burners will soot up and smell. For wood, creosote accumulates as a Class III glaze that ignites at around 1,000°F and burns like a blowtorch inside the flue. Neither is a gamble worth taking when an inspection costs $189. Call (571) 946-2300 to book your camera inspection.
