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.

AfterGelco Chimney Repair in Plano: What to Know First
We provide independent Gelco chimney repair in Plano for homeowners whose Gelco caps, crowns, or chase covers have started leaking, rusting, or separating at the seams. Most Gelco repairs we book in Plano are completed within one to two business days after our camera inspection, with a written price delivered before any work starts. We’re not affiliated with Gelco - we’re an independent service provider - which means we source parts through our Haven buying network and recommend only what the camera actually shows.
This page is for Gelco owners in Plano, Richardson, and Allen who need straight answers about whether their cap can be resealed or needs replacement, whether that rust streak is cosmetic or structural, and what it’ll cost before a tech sets foot on the roof. Call us at (469) 240-3101 for a free estimate, or read on for the specifics.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps (Model M-8, M-12, M-13 series): The 304 stainless mesh on these caps holds up well in Plano’s clay soil and alkaline water, but the cross-break lid design pools water during our spring thunderstorm season when debris clogs the corner drains. We see this on homes near White Rock Creek and in older Plano neighborhoods where oak catkins collect fast. Our fix: pull the cap, clear the drainage channels, and reseat with a bead-through silicone seal - or replace with a Gelco-replacement lid if the metal has fatigued from repeated standing water. Corrine Halstead’s crew has reseated hundreds of these; the camera doesn’t guess, and neither do we.
- Gelco Single-Flue Caps with Leg Bolts (L-8, L-12 series): The leg bolts loosen in Plano’s expansion-contraction cycles - summer roof surface temps hit 160°F, winter nights drop below freezing. The cap shifts, the mesh rubs the flue tile, and suddenly you’ve got a cap that’s crooked and flue tiles spalling at the top. We torque to spec, add locking washers where the original hardware failed, and document the flue condition with camera footage before we leave.
- Gelco Chase Covers (pre-2015 galvanized steel): Gelco switched to primarily stainless chase covers around 2015, but the galvanized units from the 2000s are still on thousands of Plano homes built during that boom. The galvanizing fails at the drip edge first - you’ll see rust streaks down the chase siding - and once water gets under the pan, it rots the framing unseen. We replace with a stainless Gelco-equivalent or, if the chase is oversized, fabricate a custom pan from heavier-gauge steel through our Copperfield supply line. Camera inspection of the chase interior is non-negotiable; Clause 4 of the Haven Standard requires the photo record.
- Gelco Wind-Resistant Caps (WR series): The hinge pins on these can seize after Plano’s dust storms and pollen seasons - the fine particulate works into the joint. Owners try to force them open for cleaning and shear the pin. We stock the Gelco-spec replacement hinge kits, but we’ve also found that a quality aftermarket pin from Olympia Chimney with a zerk fitting for annual lubrication outlasts the OEM in our climate. We explain both options and price them in writing before you choose.
- Gelco Masonry Chimney Crowns (poured concrete, not cap-mounted): When a Gelco cap is installed on a poorly sloped crown, water runs backward toward the flue. The crown cracks, the cap rusts at the base flange, and both fail together. In Plano’s black clay soil zones - think east of Preston Road - foundation movement accelerates this. We remove the cap, grind the crown to proper slope, pour a new bonded crown with expansion joint, and reinstall or replace the cap. The camera goes down the flue before and after; if the flue liner’s compromised, we quote DuraFlex or HeatShield liner work separately, never bundled.
Our Gelco Chimney Repair Process
- 1
Call and schedule. A live person answers, 24/7. We ask for your Gelco model if you know it - it’s stamped on the cap skirt or chase cover tag - and book a Level 2 inspection with camera.
- 2
Inspection and documentation. Our tech arrives in uniform, license number visible, with a text when they’re en route. We run the camera down the flue, photograph the cap or crown from the roof, and record any rust, separation, or flue damage. You get the photos before we discuss price.
- 3
Written price, written scope. We source parts through our Haven network - Gelco OEM when available, Olympia Chimney or Famco equivalents when lead times stretch or when aftermarket quality meets spec. The written price includes parts, labor, and the 365-Day Done Right Promise. No work starts until you approve in writing. Clause 1 of the Haven Standard.
- 4
Repair and testing. We complete the repair, torque to spec, seal to manufacturer guidelines, and run a final camera pass to confirm flue integrity and proper cap seating. Smoke pellet testing where applicable.
- 5
Documentation and guarantee. You receive a second photo set showing completed work, a written warranty, and our Done Right Promise stamped on the invoice. Everything goes into your record under Clause 4 - accessible if you sell the home or need warranty service.
- 6
Cleanup and follow-up. We haul old material, magnet-sweep the yard, and check in at 30 days to confirm no leaks after the next rain.

Why Plano Homeowners Call Emberly Chimney Cleaners Plano for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of the caps and chase covers we’ve documented were Gelco units - common in Plano homes built 2005-2018, when Gelco had strong distribution through regional suppliers. Our techs know the difference between a Model L-8 and an L-12 without climbing down to check the stamp.
The 365-Day Done Right Promise covers every Gelco repair we make. If the reseal leaks, the cap shifts, or the hardware loosens, we come back and make it right. No charge. That’s stamped on your invoice, not buried in fine print.
When Gelco OEM parts are back-ordered - it happens with specialty sizes - we don’t stall your job. Our Haven buying network includes DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. We quote the equivalent, explain the spec match, and let you decide. Same written price, same warranty, same Clause 4 photo record.
Calls are answered live, 24/7. Techs are background-checked, uniformed, and named before arrival. License number on every page. Corrine Halstead’s standard since she started this work: show what you found, name what it costs, then ask if the homeowner wants to proceed.
FAQs
No - Gelco’s limited lifetime warranty on stainless caps covers manufacturing defects, not installation or weather damage. As an independent Gelco service provider, we use parts and practices that don’t interfere with defect claims you might file directly with Gelco. If your cap failed due to a weld or material flaw, we’ll document that in our photo record so you have evidence for a warranty submission. Call (469) 240-3101 and we’ll inspect for free.
We source Gelco OEM when lead times are reasonable - typically 3-5 business days for common single-flue caps. For chase covers and discontinued pre-2015 galvanized models, we fabricate equivalents from stainless through our Copperfield and Olympia Chimney supply lines, matched to Gelco spec. We quote both options in writing with the spec comparison; you choose before work starts.
Resealing works when the metal is sound - minor surface rust, intact mesh, straight lid lines. Replacement is the honest call when we find pinholes through the lid, mesh separation from the frame, or leg bolt holes wallowed out beyond re-torque. Our camera inspection shows you the flue condition too; sometimes a cap looks fine but the flue tile top is spalling, and that changes the scope. We explain both scenarios and price them separately - no bundled surprises.
Every 12 months, ideally before our March-May storm season. Plano’s combination of pollen, oak debris, and sudden hard rain tests drainage designs hard. The multi-flue caps especially need corner drain clearance. Annual inspection catches the standing water before it fatigues the metal. We document each visit with photos under Clause 4, so you can track condition year over year.
Water enters the chase framing, rots the wood, and eventually stains interior ceilings or compromises the flue liner support. In Plano’s humid summer months, that moisture also accelerates corrosion of any galvanized gas vent passing through the same chase. The repair escalates from a chase cover replacement to framing repair, liner work, and interior drywall. Our camera inspection shows you exactly where water is entering - if it’s still just the cover, we say so. If the framing’s wet, we show you that too, and price both scenarios. Call (469) 240-3101 for a free estimate.
