Chimney Sweeping, Cleaning & Inspection

Professional chimney sweeping, chimney cleaning, and NFPA Level 1, 2, and 3 inspections designed to remove hazardous creosote buildup, identify safety concerns, and keep your fireplace operating safely and efficiently.

Custom chimney caps and crown repair solutions help prevent water damage, animal entry, debris buildup, and premature masonry deterioration while extending the life of your chimney system.

Fireplace Install
★★★★★

"They replaced an old propane fireplace with a new one. Ted was great in the beginning and kept communication throughout. Dave, Dave & Rob were the team assigned throughout the job and were fantastic with getting everything insulated/sealed, up to code, new unit in, explaining and showing how to use it. Would recommend to anyone needing a new unit or service!"
