Technician Bryan Bowlin recently completed a masonry waterproofing service on Damascus Road in Gaithersburg, MD , helping protect a chimney from moisture damage and future structural issues.

Water is a chimney’s worst enemy—over time, it seeps into porous brick and mortar, leading to cracking, spalling, and costly repairs. Chelsea’s Chimney uses high-grade breathable sealants that defend against water intrusion without trapping moisture inside the masonry.

Whether your chimney is aging or brand-new, waterproofing is one of the smartest preventative steps you can take.
