We’re an independent DuraFlex service provider. We are not affiliated with or authorized by DuraFlex. What we are is a chimney company that has worked on enough DuraFlex installations across Nassau County to know what goes wrong with them, what holds up, and how to clean them without voiding a warranty or making a small problem worse.

How DuraFlex Products Fail – and How We Fix Them

DuraFlex makes a solid liner, but every product line has its weak points. Here’s what we actually see on Hempstead rooftops, not what the brochure says.

• DuraFlex 316L single-wall liners and creosote glazing. These liners handle wood-burning appliances, and in Hempstead’s humid falls, creosote doesn’t flake off the way it does in drier climates. It glazes. A glazed liner surface looks shiny and hard, and a standard brush pass won’t remove it. We see this most often in older Hempstead homes where the fireplace gets used on weekends from October through March. Our fix is a chemical treatment followed by a rotary whip, then a camera check to make sure the glaze is gone and the corrugations aren’t scored.
• DuraFlex Pro and liner seam distortion from over-aggressive cleaning. We have repaired liners in Hempstead that previous crews cleaned with metal chains or oversized brushes. The Pro line’s interlocking corrugations are strong, but they are not indestructible. Oversized tools can stretch seams and create gaps that let flue gases escape into the chase. Our techs measure the liner before every sweep and use brushes sized to the exact ID, never a one-size-fits-all.
• DuraFlex 304L and condensation pitting near the top termination. In Hempstead, we get sharp temperature swings in late winter. A warm flue meets cold air at the cap, and condensation forms inside the upper corrugations. On 304L liners, that condensation carries acids that pit the metal over time. Homeowners can’t see this from the ground. We check the top three feet during every sweep. If we find pitting, we quote a cap improvement or a top-section replacement, and only if the camera shows it’s needed.
• DuraFlex smooth-wall hybrid and soot accumulation at the transition point. Some Hempstead homes run a smooth-wall DuraFlex section from the stove up through the smoke chamber, then a corrugated section to the top. Soot loves to collect where the profile changes. A homeowner notices the stove drafting weaker. We clean that transition carefully because lazy crews miss it entirely and call the job done.
• DuraFlex aluminum liners on gas systems and clogging at the termination. Gas liners don’t get creosote, but they do get debris. In Hempstead, tree litter and squirrel nests find their way into uncapped or mis-capped terminations. An aluminum DuraFlex liner that clogs at the top sends carbon monoxide back into the house. We sweep these, yes, but we also inspect the cap and termination every single time. If the cap is missing or wrong for the liner, we say so.

Our DuraFlex Chimney Sweep Process

Every DuraFlex job in Hempstead follows the same sequence. No shortcuts, no surprises. Here’s how it works when you call (516) 559-6922:

1. 1
   Phone quote range. You tell us what you have – wood stove, fireplace insert, gas appliance – and the liner type if you know it. We give you a written price range before we ever dispatch a truck.
2. 2
   On-site inspection and written fixed price. The tech arrives in uniform, confirms the liner, measures the flue ID, and hands you a written price. That number is the number. If we find something during the sweep that changes the scope, we stop, show you, and re-price before continuing.
3. 3
   Flue prep and protection. We lay drop cloths, seal the fireplace opening, and set up dust containment. A DuraFlex liner means the flue itself is smooth, so dust control matters more than with an old clay tile flue that catches everything. We don’t leave Hempstead living rooms covered in soot.
4. 4
   The sweep, sized to the liner. We use poly or nylon brushes sized to the exact liner ID. No oversized metal tools. For glazed creosote, we use a chemical treatment and rotary whip. The liner determines the tool, not the other way around.
5. 5
   Camera inspection and honest report. We run a camera through the flue after cleaning. Every DuraFlex sweep includes this. You see what we see. If the liner’s fine, we tell you it’s fine. If it’s not, we show you the footage and quote a fix that matches the problem – no more, no less.
6. 6
   Cleanup, test, and guarantee paperwork. We vacuum the firebox, check the damper, and run a draft test if the appliance is in use. Then we hand you paperwork including your written 365-Day Done Right Promise. If anything we serviced fails within one full year, we return at no charge.

Hank Delano has been running crews this way across Nassau County long enough to know that a clean job and a straight answer beat a fast job every time. The flue tells the truth. You just have to know how to read it.

What DuraFlex Chimney Sweep Costs in Hempstead

Here’s the pricing structure for DuraFlex work in Hempstead, straight and range-banded. These are typical ranges, not quotes – your price gets set in writing before anything starts.

• Standard DuraFlex sweep, Level 1 inspection, camera check: $189 – $289

Why Hempstead Homeowners Call Flint Chimney Co Hempstead for DuraFlex Work

We are part of the Garrison Partners family, founded in 2002, and we operate under The Garrison Standard – the same code every Garrison Partners location follows. That means a written price before work starts on every single job, no exceptions. It means background-checked, uniformed technicians on every call. It means a live person answers the phone at (516) 559-6922 at 2 p.m. or 2 a.m. And it means every repair we make carries the 365-Day Done Right Promise: a written guarantee valid for one full year from the service date. If a covered repair fails in that window, we come back and make it right at no charge. No argument, no re-invoicing.

We work with DuraFlex daily, but we also stock and install HeatShield and Gelco materials when a repair calls for a different approach. That matters in Hempstead, where a liner replacement sometimes isn’t the right answer, and a resurfacing treatment is. We recommend what the flue needs, backed by camera footage you watch with us. Not what pads the invoice.

Hank Delano, our owner, learned the trade at Los Angeles Trade-Technical College and has spent the better part of two decades running chimney crews across Nassau County, including steady work in Hempstead’s Fulton neighborhood. He built this company around one idea: put the condition of the flue in plain words, put the price in writing, and let the work prove the rest.
