This page is for homeowners in neighborhoods like Centennial, Dorsey’s Search, and the historic district near Main Street who have a HeatShield liner, crown coat, or refractory product and need it cleaned, inspected, or evaluated for safe burning season use. If you are unsure which HeatShield product is in your chimney, we can identify it on arrival. Call (410) 305-7884 - a live person answers, 24 hours a day.

How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing develops hairline cracks near the smoke shelf. The CFM series relies on a sprayed ceramic refractory layer that can delaminate where temperatures spike during shoulder-season burns, which in Ellicott City means those damp October evenings when homeowners light small, smoldering fires. We remove the degraded material with mechanical abrasion, prep the substrate with HeatShield-compatible bonding agent, and respray to factory thickness. The flue doesn’t lie - we just translate what it’s telling you.
• HeatShield CrownCoat shrinks and pulls from masonry edges after five to seven winters. Ellicott City’s freeze-thaw cycle is aggressive; the Patapsco River valley traps cold air, and CrownCoat applied too thin at the drip edge cracks first. We strip the failed coat, re-profile the crown slope for positive drainage, and reapply at 3/8-inch minimum thickness using HeatShield-specified primer.
• ProForm stainless steel liner sleeves separate at factory seams during creosote-heavy burns. The ProForm 316Ti series flexes well but the longitudinal seam can gap if creosote buildup restricts draft and the liner overheats in one section. We camera-inspect the full length, mark the separation point, and either weld-repair or sleeve-within-a-sleeve depending on accessibility from the Ellicott City roofline.
• HeatShield Refractory Mix (HRM) palls and spalls in wood-pellet conversions. Homeowners near Ilchester who switched from cordwood to pellets without adjusting the flue often see HRM breakdown from acidic condensate; pellet exhaust is wetter and cooler than the material was designed to handle. We remove the degraded refractory, evaluate whether a stainless liner is the smarter long-term fix, and reline with DuraFlex or Gelco if the appliance change warrants it.
• Joint repair compound in older HeatShield flue rebuilds crumbles at mortar beds. Pre-2010 HeatShield joint repairs used an earlier formulation that loses flexibility; after 42 years in this trade, we have seen it in Ellicott City colonials built in the 1970s with original flues. We grind out the old compound, re-point with current-spec HeatShield joint filler, and run a vacuum-draw smoke test to confirm draft integrity.

Our HeatShield Chimney Cleaning & Sweep Process

1. 1
   Call intake with live person. We ask your HeatShield product series if you know it, the appliance type, and any symptoms - odd draft, smell, or visible debris. We schedule a window and confirm upfront pricing.
2. 2
   Arrival and Level 1 or Level 2 inspection. Our background-checked, uniformed technician lays protection, runs a visual flue check, and decides whether camera work is warranted based on what we find.
3. 3
   HeatShield-specific diagnostics. We identify your product line by visual markers - CFM texture pattern, CrownCoat color batch, ProForm seam stamp - and check for the failure modes we know from experience in this climate.
4. 4
   Parts and repair decision. OEM HeatShield materials when available; quality aftermarket from our Copperfield and Famco supply when lead times stretch, with your approval and full disclosure. No surprises on the bill.
5. 5
   Sweep, repair, and test. Rotary cleaning with HEPA containment, any refractory or liner work, then draft test and smoke check. Photos you can see, a plain-English verdict.
6. 6
   Written documentation and guarantee. You get the inspection report, photos, and the 90-Day Done Right Promise - in writing, no arguing. Done right, and we stand behind it.

What HeatShield Chimney Cleaning & Sweep Costs in Ellicott City
