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.

AfterTrusted Chimney Liner & Rebuild for Wilmington Homeowners
Chimney liner replacement and chimney rebuilds in Wilmington typically cost between $2,800 and $8,500 depending on whether you’re relining a single flue or rebuilding from the roofline up. Most liner jobs we book in Wilmington are completed in one day; full rebuilds usually take two to three days, weather permitting. Call (610) 546-5053 and we’ll send a written estimate before any work starts.
We’ve inspected more than 38,000 chimneys since 2009, and the ones that scare us aren’t the old ones - they’re the ones where a homeowner didn’t know the liner was compromised until something went wrong. In Wilmington’s older neighborhoods like Forty Acres and Hilltop, we regularly find clay tile liners that cracked during the freeze-thaw cycles of the 2010s, or unlined brick chimneys still venting modern gas appliances. The former carriage houses near Trolley Square and the post-war splits in Elsmere present their own patterns: too-narrow flues, improper connector pipes, or previous owners who patched instead of rebuilt. Corrine Halstead and our team at Level Two Chimney Co. document every condition with a camera-scan inspection, then deliver a written price, written scope, and written warranty before anyone picks up a tool. That’s Haven Standard Clause 1: Have it in writing. Always.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe dropped down your chimney to contain combustion gases and protect the surrounding masonry. In Wilmington, we install stainless steel liners most often when clay tile flues have cracked or shifted, or when a homeowner is converting a fireplace to a wood or gas insert that requires a specific flue diameter. Our crews use DuraFlex and Olympia Chimney stainless products, sized to your appliance’s BTU output and your chimney’s interior dimensions. Every stainless installation includes a camera-scan verification that the full length is seated and sealed, plus a photo record archived under Haven Standard Clause 4.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that navigate offsets and bends in chimney flues where rigid pipe won’t fit. We see this need frequently in Wilmington’s pre-1940 homes near Little Italy and the riverfront, where chimneys were built with sharp turns to accommodate floor joists or former coal chutes. Flexible liners from DuraFlex allow us to reline these complex flues without dismantling walls or structural masonry. The installation still gets a full camera inspection, pressure test where applicable, and the same written warranty as our rigid installations.
Liner Replacement
Liner replacement means removing a failed or obsolete flue liner and installing a new one to current NFPA 211 standards. In Wilmington, we replace liners that have spalled (flaked apart from heat cycling), separated at the joints, or been damaged by chimney fires - the latter often goes unreported because the fire burns itself out before the fire department arrives. We also replace liners that were never the right material for the fuel being burned, such as aluminum liners venting wood stoves. Our replacement process starts with a Level 2 inspection to determine why the original liner failed, so the new one doesn’t repeat the same problem.
Partial Rebuild
A partial rebuild addresses the section of chimney that’s actively failing - typically the crown, the top several courses of brick, or a damaged smoke chamber - while leaving sound lower masonry in place. In Wilmington, partial rebuilds are common after ice dam seasons when water has infiltrated the crown and frozen, popping off brick faces or separating the crown from the flue wall. We rebuild with matching brick where possible, pour a new concrete crown with proper drip edges and slope, and install a flue cap to prevent recurrence. The scope is written line by line, and we photograph before, during, and after.
Full Chimney Rebuild
A full chimney rebuild means dismantling the existing structure to the roofline (or below, if the foundation is compromised) and constructing a new chimney to current code. We perform full rebuilds in Wilmington when chimneys have suffered structural settlement, extensive freeze-thaw damage, or multiple unaddressed chimney fires that have cracked the wythes (the internal brick partitions). Our rebuilds include proper clearance to combustibles, a correctly sized flue liner, and a cricket or saddle on the uphill side if the chimney is on a pitched roof - a detail we see missing on many older Wilmington homes that contributes to the leaks that started the damage cycle.
Liner Repair
Liner repair is a targeted fix for localized damage: a cracked tile at the top of the flue, a deteriorated mortar joint between tiles, or minor spalling that hasn’t compromised the full system. In some cases, we can apply HeatShield cerfractory sealant to smooth and seal a rough or pitted clay flue surface, restoring draft performance without full replacement. We only recommend repair when a camera inspection confirms the damage is truly isolated and the remaining liner is sound; otherwise, we tell you plainly that repair would be a temporary patch and recommend replacement. No upsell, no omission - just what the camera shows.

Brands We Service for Chimney Liner & Rebuild
We source liner and rebuild materials through Haven’s buying network, which was built specifically to keep customer prices honest by purchasing at volume from manufacturers who publish their specifications openly. For stainless and flexible liners, we install DuraFlex and Olympia Chimney products - we’ve completed hundreds of DuraFlex installations in the Wilmington area and stock the common diameters and termination caps so we’re not ordering your parts after you’ve already taken time off work. For refractory repair and resurfacing, we use HeatShield’s cerfractory foam system, which we apply with their factory-specified pumping equipment and cure with controlled heat per their protocol. For caps, dampers, and termination hardware, we specify Famco and Copperfield components selected for your fuel type and local wind exposure.
Whether your existing liner is one of these brands or you’re not sure what you have, we identify it during the camera inspection and explain what we found before recommending any product. If you have a written estimate from another company specifying a brand we don’t carry, bring it in - our Free Second Opinion policy means we’ll review their scope and pricing against what we see in your flue, with no obligation to book with us.

AfterSigns You Need Chimney Liner & Rebuild Right Now
- White staining (efflorescence) on exterior brick means water is moving through the masonry and depositing salts as it evaporates. In Wilmington’s climate, this accelerates after wet winters, and it’s often the first visible sign that the liner has cracked and exhaust gases are condensing inside the chimney instead of exiting properly. The moisture carries acids that break down mortar joints from the inside.
- Flakes or grit in the fireplace or cleanout are pieces of clay tile liner that have spalled from heat stress or freeze-thaw damage. Once tiles start shedding material, the protective barrier between combustion gases and combustible framing is compromised. We’ve found tile debris in Edgemoor homes where the homeowner assumed it was just “soot falling down.”
- Smoke or odors entering living spaces indicate a breach in the liner, a blocked flue, or negative pressure pulling exhaust back into the house. This isn’t just unpleasant - it’s a carbon monoxide risk if you’re burning gas, and a particulate hazard with wood. Any smoke intrusion warrants an immediate Level 2 inspection with camera documentation.
- Visible cracks in the chimney crown or missing mortar joints allow water directly into the chimney structure. Wilmington’s freeze-thaw cycles, particularly the wet winters of 2018 and 2020, expanded small cracks into structural failures in dozens of chimneys we’ve rebuilt. Crown damage always gets worse; it never self-heals.
- A recent chimney fire, even a small one can crack clay tiles, warp metal liners, or damage the surrounding masonry enough to require rebuild. Many chimney fires go undetected - a loud roaring or popping sound, sudden smoke backup, or a discolored rain cap are the usual clues. If you suspect you’ve had one, the liner needs camera inspection before the next burn season.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Level 2 Inspection with Camera Documentation - We start every liner and rebuild job with an NFPA 211 Level 2 inspection: camera down the flue, photos of every surface, measurements of clearances and flue dimensions. In Wilmington, we often find previous repairs that weren’t permitted or liners that were “sized by eye” instead of by appliance specification. You get the photo record before we discuss solutions. Haven Standard Clause 4 requires this documentation on every visit.
- 2
Written Scope, Written Price, Written Warranty - Within 24 hours of inspection, we deliver a single-page proposal listing exactly what we’ll do, what materials we’ll use, what it costs, and what our 365-Day Done Right Promise covers. No verbal quotes, no “we’ll see when we get into it,” no surprise charges. Clause 1 of the Haven Standard: Have it in writing. If the scope changes because we find concealed damage, we photograph it, explain it, and get your approval before continuing.
- 3
Material Procurement and Scheduling - Once you approve, we order materials through our buying network and schedule your job. For standard stainless liners, we often have stock on hand; custom diameters or full rebuild brick matching may add a few days. We confirm your appointment by text, send technician details including name and license number, and notify you when they’re en route.
- 4
Installation or Rebuild with Continuous Documentation - Our background-checked, uniformed technicians perform the work with dust containment and floor protection as standard. For rebuilds, we photograph each course of brick and the tie-in to existing masonry. For liners, we camera-verify the full insertion depth and seal integrity. You can watch the camera feed if you’re home, or review the photos afterward.
- 5
Final Inspection, Photo Archive, and Warranty Activation - We perform a post-installation camera scan, test draft performance where applicable, and clean the work area completely. Your final packet includes the photo record, the completed scope checklist, and your warranty documentation. The 365-Day Done Right Promise is active from that date - if anything isn’t right, we make it right. The full record stays in our archive for future reference or resale documentation.
How Much Does Chimney Liner & Rebuild Cost in Wilmington?
A typical stainless steel liner installation runs $2,800-$4,500 for a single-flue system, depending on height, diameter, and whether we need to remove an existing damaged liner first. Flexible liner installations in offset chimneys range $3,200-$5,000. HeatShield resurfacing for localized liner repair is usually $1,800-$2,800 when the underlying clay tile is sound. Partial rebuilds - crown, top courses, and cap replacement - typically fall between $3,500 and $6,500. Full chimney rebuilds from the roofline up generally range $6,500-$8,500, with foundation work or extensive lead flashing replacement adding to that if needed.
Several factors move these numbers. Chimney height above the roofline is the biggest variable; a three-story flue in a home near Rockford Park requires more liner footage and more scaffolding than a ranch in Wilmington Manor. Access matters too - tight side yards, steep pitches, or delicate landscaping limit equipment placement and add labor time. The condition of the existing liner affects whether we can pull it in one piece or must break it out course by course. And fuel type drives material selection: wood-burning appliances need higher-grade stainless (316Ti) than gas-only systems (304), per manufacturer warranty requirements.
To avoid overpaying, get any estimate in writing with line-item scope, and compare what’s actually included. Some Wilmington-area companies quote a liner price that excludes the connector pipe, the termination cap, or the required inspection - then add them after arrival. Our price includes the full system, the inspection, the photo record, and the warranty. We also offer a Free Second Opinion on any competitor’s written estimate; bring it in and we’ll tell you where the scopes differ and why.

Frequently Asked Questions - Chimney Liner & Rebuild in Wilmington
Chimney liner work installs or repairs the protective pipe inside your chimney that contains heat and combustion gases; rebuild work repairs or reconstructs the masonry structure surrounding it. Together they ensure safe venting and structural integrity. In Claymont and throughout Wilmington’s housing stock, we most often perform both on the same chimney because liner failure and masonry deterioration are usually caused by the same moisture intrusion problem.
Most stainless steel liner installations are completed in one day; full chimney rebuilds typically take two to three days depending on weather and cure times for mortar and crown concrete. We schedule rebuilds with buffer days for rain, and we never rush cure times - a crown poured on Friday that freezes Saturday night will crack before spring. You’ll get a firm date range in your written scope, not a vague “sometime next week.”
Stainless liner installations typically run $2,800-$4,500; partial rebuilds $3,500-$6,500; full rebuilds $6,500-$8,500. For our Chimney Liner & Rebuild in Pennsville, pricing follows similar ranges. The exact price depends on chimney height, access difficulty, liner diameter, and whether concealed damage appears during removal. We deliver a written, line-item price before any work starts - no exceptions. Call (610) 546-5053 for a free estimate specific to your chimney.
Yes - we install DuraFlex and Olympia Chimney liners, apply HeatShield cerfractory sealant, and specify Famco and Copperfield hardware as standard. We’ve completed hundreds of installations with these products and stock common sizes and components. If your existing liner is another brand, we identify it during camera inspection and can match or exceed its specifications with our sourced materials.
We answer calls live 24 hours a day, 7 days a week, and we prioritize situations involving active water intrusion, suspected carbon monoxide leakage, or post-chimney-fire damage. True emergencies get same-day inspection if possible; we don’t promise same-day completion for full rebuilds because cure times and permits can’t be rushed, but we can often install a temporary liner or cap to make the system safe until permanent work is scheduled.
Every job is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. Manufacturer warranties on stainless liners typically run lifetime for the original homeowner; HeatShield carries a 20-year limited warranty. Our workmanship warranty covers installation quality for one year, and we extend that to the full 365 days under our promise. All warranty terms are written and included in your final packet, not verbal assurances.
Clear a path from your driveway or street access to the chimney area, move vehicles that block equipment placement, and cover or remove furniture near the fireplace if the work involves interior access. For rebuilds, expect some vibration and dust; we contain it but can’t eliminate it entirely. Keep pets secured and plan to be available by phone even if you’re not home - we may need to discuss concealed conditions the camera reveals once we’re inside the flue. We’ll text when the technician is en route so you’re not waiting around.
