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.

AfterHeatShield Chimney Cap & Crown in McKinney: What to Know First
We provide independent HeatShield chimney cap and crown service in McKinney, typically scheduling within 3-5 business days and completing most jobs in a single visit. Every repair starts with a camera inspection down the flue and a written price on paper before any work begins. This page is for HeatShield owners in McKinney, Allen, and Frisco who need cap or crown work and want to know what their specific product requires, what it costs, and whether the fix can wait. Call (469) 429-2623 to book a free estimate.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam liner systems with cracked or missing crown wash. HeatShield’s Cerfractory Foam (the white refractory coating applied to clay flue liners) sheds water poorly when the concrete crown above it is cracked or pitched wrong. In McKinney, the clay-heavy soil shifts with seasonal moisture swings, and we’ve found crown separations on Cerfractory jobs in Stonebridge Ranch and Craig Ranch that let water migrate straight to the foam-to-clay interface. We remove the failed crown section, re-pitch for drainage away from the flue, and reseal with HeatShield-compatible crown coat or pour new concrete if the structural shell is compromised.
- ProForm stainless caps with crevice corrosion at the mesh-to-frame weld. HeatShield ProForm multi-flue caps use 304 stainless mesh in most residential specs, but the weld points where mesh meets the raised frame collect acidic condensation when flue gases cool before exit. McKinney’s hard water and occasional ice events accelerate this. We spot-weld repair only if the frame is sound; otherwise we source ProForm OEM replacements or match with Gelco equivalent gauge mesh that carries the same spark arrestor rating without the OEM markup.
- Joint Repair systems with water intrusion from cap overhang gaps. HeatShield Joint Repair (the sleeve-and-resin method for separating flue tiles) depends on a dry flue environment to cure and bond. When the existing cap’s overhang is too short or the screen height is wrong, driving rain enters and pools at the joint line. We’ve pulled failed Joint Repair jobs in older McKinney homes near Historic Downtown where the cap was original to a 1980s build and never matched to the HeatShield retrofit. We measure flue projection, calculate proper screen height for your roof pitch, and install a cap with minimum 5-inch overhang per NFPA 211.
- Cerfractory Foam with spalling concrete crown exposing the foam edge. The foam application stops below the crown line by design, but crown spalling (surface flaking from freeze-thaw or bad mix) exposes that edge to direct water. McKinney sees 15-20 freeze-thaw cycles most winters, enough to wreck a crown with excess Portland cement. We grind back to sound concrete, apply a bonding agent, and pour a new crown with air-entrainment mix rated for North Texas. If the foam edge is damaged, we feather-repair with HeatShield’s factory resupply material, not generic refractory patch.
- ProForm and standard caps with improper flue clearance causing draft stall. HeatShield caps specify minimum flue gas clearance to the screen bottom, but installers who don’t read the sheet often set the cap too low. The result is draft reduction, smoke spillage on startup, and accelerated creosote formation that voids your warranty language. Our techs measure flue diameter, calculate required screen height per the ProForm spec sheet for your model, and shim or replace the cap accordingly. We document the measurement in your photo record.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, checks HeatShield part availability with our Haven buying network, and books your camera inspection. You’ll get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. We run the camera down the flue to locate the failure, photograph the crown or cap condition from the roof, and note any HeatShield product labels or application dates visible on the liner. Corrine Halstead reviews the footage with you on-site or via shared link before quoting.
- 3
Written scope and price. We specify OEM HeatShield parts versus quality aftermarket alternatives (DuraFlex or Gelco equivalents where compatible), list labor line items, and stamp the 365-Day Done Right Promise. No work starts until you have the paper in hand. The camera doesn’t lie, and neither does the written quote.
- 4
Repair or replacement. For crowns, we form and pour or coat depending on structural integrity. For caps, we remove the failed unit, verify flue dimensions against the new spec, and install with stainless fasteners and high-temp sealant rated to 1,200°F.
- 5
Post-work camera verification and photo record. We re-run the camera to confirm no debris entered the flue during cap removal, photograph the finished crown or cap from multiple angles, and upload everything to your documented record under Haven Standard Clause 4.
- 6
Cleanup and warranty documentation. You receive a written warranty, the photo record link, and our direct line for any callback. The 365-Day Done Right Promise covers labor and materials.

Why McKinney Homeowners Call Level Two Chimney McKinney for HeatShield Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of McKinney’s 2015-2025 housing stock includes HeatShield retrofits from the original build or a prior owner’s upgrade. Our techs carry the Haven Standard on every call: background-checked, uniformed, license number visible, with a text when we’re en route. We source HeatShield materials through our Haven buying network alongside DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield - so if your HeatShield part is backordered, we can cross-match a compatible spec without leaving you exposed through burn season. Every job gets Clause 4’s documented photo record, and our Free Second Opinion applies to any competitor’s written estimate you bring us. We’re independently owned and operated, not a franchise, and Corrine Halstead still reviews camera footage personally on jobs near McKinney’s older districts where the mortar tells a story the flashing hides.
FAQs
No, if the work is performed by a technician who follows HeatShield’s published installation tolerances and uses compatible materials. As an independent HeatShield service provider, we document our methods and materials so any warranty claim you file later has the backup documentation it needs. If you’re unsure about your warranty status, we can photograph the original application labels during inspection and help you read the coverage terms. Call (469) 429-2623 to schedule.
Most cap replacements and crown coatings finish in 2-4 hours; full crown rebuilds typically take a full day including cure time for the bonding agent. We don’t rush the concrete cure or the foam edge seal, because both fail prematurely if installed wet. We’ll give you a specific time estimate in your written scope before booking. Call (469) 429-2623 for a free estimate.
We source both. OEM ProForm caps and factory Cerfractory resupply material come through our Haven buying network at prices we publish in writing. When OEM lead times stretch past burn season, we cross-match DuraFlex or Gelco equivalents that meet the same spark arrestor, gauge, and temperature specs - and we tell you which we’re proposing before you sign. Call (469) 429-2623 to discuss what’s in stock for your model.
We tap-test the crown surface and camera-inspect the underside through the flue. If the concrete is sound more than 1.5 inches deep and the steel reinforcement isn’t exposed, coating is usually sufficient. If we find hollow spots, through-cracks, or rebar rust jacking the surface, we recommend rebuild - and we show you the camera evidence before quoting either option. Call (469) 429-2623 for an inspection.
Water enters the flue, degrades the Cerfractory Foam or Joint Repair bond, and can reach the smoke chamber and firebox masonry behind it. In McKinney’s climate, that water cycle repeats 30-40 times per year. The repair you delay becomes a liner reline or firebox rebuild you can’t postpone. We don’t scare-sell: if the camera shows the damage is minor and the flue is otherwise sound, we’ll say so plainly and note it for next year’s inspection. Call (469) 429-2623 for an honest assessment.
