A Emberly company - serving Marietta, GA

Gelco Chimney Liner & Rebuild Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Gelco Chimney Liner & Rebuild in Marietta: What to Know First

We provide independent Gelco chimney liner and rebuild service in Marietta, with most Gelco liner replacements and partial rebuilds scheduled within a week of your call. Every job starts with a camera-scan inspection and a written price before any work begins - no exceptions. Gelco stainless steel liners and flexible liner kits are common in Marietta homes built between 1995 and 2015, especially in subdivisions off Whitlock Avenue and around Kennesaw Mountain where clay flue deterioration accelerates in our freeze-thaw cycles. If you own a Gelco liner that is leaking, pulling away from the top plate, or showing rust streaks at the collar, we can inspect it, name the exact repair, and quote it in writing. Call (470) 288-2763 to schedule.

How Gelco Products Fail - and How We Fix Them

  • Gelco UltraPro flexible liners: The corrugated walls on UltraPro kits can develop stress fractures at the first bend above the smoke chamber, particularly in Marietta’s older ranch homes with 45-degree offsets. We see this where the liner was pulled too tight during original installation. Our fix is a custom-measured replacement with an additional insulation wrap at the stress point, or a rigid stainless section at the offset if clearance allows.
  • Gelco round top plates and storm collars: The galvanized top plates on pre-2010 Gelco systems rust through at the collar weld in about 12-14 years here - faster than the manufacturer estimates because Marietta’s humidity stays above 70 percent for five months straight. Water runs down the flue and pools behind the fireplace damper. We replace with a 304 stainless top plate and silicone-sealed storm collar, and we always check the crown for reverse slope that would send water back toward the flue.
  • Gelco smooth-wall rigid liners: Thermal expansion causes the male-female joints to separate by 1/8 to 3/16 inch after 10-15 years of heating cycles. This gap leaks flue gases into the chimney cavity and shows up as warm spots on infrared during our Level 2 inspection. We reseat the joint with a mechanical lock band and refractory sealant, or replace the section if the gap has allowed creosote to accumulate in the cavity.
  • Gelco liner-to-appliance connections: The slip connectors that join Gelco liners to wood inserts or oil furnaces loosen as gaskets harden. In Marietta, we find this most often on second-home installations where appliances cycle less frequently. A loose connection dumps carbon monoxide potential directly into the living space. We replace the connector with a proper Gelco-compatible adapter and test draft and spillage with a manometer before we leave.
  • Gelco chimney liner supports: The bottom support brackets on multi-story installations can corrode where they contact the clay flue base, especially if the original mason left mortar debris in the flue. The liner drops an inch or two, tilting the top plate and opening a gap at the storm collar. We install a new support with a stainless base plate and document the liner position with pre- and post-repair photos under Haven Standard Clause 4.

Our Gelco Chimney Liner & Rebuild Process

Our Gelco Chimney Liner & Rebuild Process
  1. 1
    Camera-scan inspection: We run a chimney camera the full length of your Gelco liner before quoting any work. Corrine Halstead started this practice in 2009, and it became Clause 4 of the Haven Standard: no price without a picture of what needs fixing.
  2. 2
    Written scope and price: You get a written description of what we found, what we propose, the exact parts, and the total cost. We do not start work until you have this document and have signed it. Camera first, quote second, work third - in that order, every time.
  3. 3
    Parts decision: For Gelco systems, we source OEM Gelco components when they are available and cost-competitive. When Gelco lead times stretch past two weeks or the OEM part has a known design weakness, we specify quality aftermarket equivalents from DuraFlex or Olympia Chimney and note the substitution in writing.
  4. 4
    Installation and testing: We install to NFPA 211 standards, pressure-test sealed joints on rigid liners, and verify draft and spillage on all solid-fuel and oil-gas connections. The technician who did the work signs off on a checklist you keep.
  5. 5
    Photo record and guarantee: We deliver dated before-and-after photos, a written warranty, and the 365-Day Done Right Promise. If anything is not right, we make it right. That is Haven Standard Clause 1.

What Gelco Chimney Liner & Rebuild Costs in Marietta

These are the price ranges we have written for Gelco liner and rebuild work in Marietta over the past 24 months. Your exact price comes after inspection.

  • Gelco flexible liner replacement (single story, wood-burning): $2,800-$4,200
  • Gelco flexible liner replacement (two story or steep offset): $3,600-$5,400
  • Gelco rigid smooth-wall liner section replacement (partial): $1,800-$3,200
  • Gelco top plate, storm collar, and seal kit: $680-$1,100

  • Full chimney rebuild with new Gelco-compatible liner system: $9,500-$14,000

What moves the price: height of the chimney, accessibility (steep roof pitches common near Kennesaw Mountain add labor), whether the existing liner can be extracted intact or must be cut out, and the condition of the clay flue tiles we are lining over. We also sweep and camera-inspect first; if your liner only needs cleaning and the top plate resealed, that is a $400-$650 job, and we will tell you so. Call (470) 288-2763 for a free estimate - we will inspect first and quote in writing.

Why Marietta Homeowners Call Emberly Chimney Cleaners Marietta for Gelco Work

We are an independent Gelco service provider, not a factory-authorized dealer, which means we can recommend the right fix rather than the catalog part. Our technicians carry Gelco, DuraFlex, HeatShield, and Olympia Chimney materials on every truck, so we are not waiting on a single supplier to get your system safe. The 365-Day Done Right Promise applies to every Gelco job we touch, and our documented photo record - standard since 2009, now Haven Standard Clause 4 - gives you dated evidence of condition for your insurer or home sale. Corrine Halstead has inspected chimneys across Marietta for nearly two decades, including plenty of afternoons on older homes along Whitlock Avenue where the masonry tells its own story. She runs a camera before quoting a price and writes down every finding in plain language before asking anyone to sign. That is the inspection standard we work to.
