This page is for Columbia homeowners who already have a HeatShield product installed - a Cerfractory Sealant resurfacing, a HeatShield Pro liner, or a factory-built chimney component - and need someone who knows how these specific systems age in Maryland’s freeze-thaw climate. We’re not HeatShield’s authorized dealer. We’re an independent HeatShield service provider with 42 years of chimney work behind us, and we’ve learned how these products behave when November’s first cold snap hits Kings Contrivance or River Hill.

How HeatShield Products Fail - and How We Fix Them

• Cerfractory Sealant flaking in the smoke chamber. The HeatShield Cerfractory system resists heat well, but in Columbia’s older homes - especially those built in the 1970s around Harper’s Choice or Wilde Lake - we’ve seen the sealant delaminate where the original parging was oil-contaminated or where moisture wicked through a cracked crown above. We grind back to sound masonry, apply HeatShield-compatible bonding agent, and resurface to factory thickness. Done right, and we stand behind it.
• HeatShield Pro liner pinholing at the flue collar. The Pro series stainless liner handles condensing appliances, but the collar joint is the weak point we’ve tracked in Columbia’s high-efficiency gas conversions. Hard water scale and acidic condensate attack the seam. We sleeve with a new Pro collar section or, if the damage extends, transition to DuraFlex for a longer-term fix - always with a camera inspection first so you see what we see.
• Crown wash cracking over factory-built chimney chase covers. HeatShield’s crown resurfacing product shrugs off thermal shock, but when the underlying chase cover is galvanized steel with a 15-year life in Maryland’s humidity, the cover flexes and the crown cracks anyway. We replace the chase cover with a Gelco or Copperfield stainless unit, then resurface the crown. Photos you can see, a plain-English verdict.
• Spalling brick behind a HeatShield relined flue. Homeowners assume the liner solved everything. It didn’t. In Columbia’s clay-heavy soil, lateral water pressure pushes moisture through the wythe, and the brick faces pop while the liner looks fine. We remove the damaged courses, repoint with matching mortar, and address the water source - usually flashing or crown - before the liner’s warranty gets voided by surrounding masonry failure.
• Factory-built chimney panel separation in the Pro Series 3000. The interlocking refractory panels shift during the expansion-contraction cycles of a Maryland winter, especially when homeowners burn green oak or run short, hot fires. The gap opens, metal overheats, and you smell hot paint. We reset to factory clearances with new HeatShield Pro panels where available, or engineer a compatible panel set from Olympia Chimney when HeatShield’s lead time stretches past burning season.
