Brick Fireplace Laser Cleaned
Roger laser-cleans an 80-year-old brick fireplace with 3/8 inch of pitch tar, creosote, and soot using a Netalux at 415 mm standoff. Heavily contaminated brick required repeated passes — no chemicals, no sandblasting, no contact damage to mortar joints.
Z-Beam was great, very professional and accommodating.

Frequently Asked Questions
What does this Brick Fireplace Laser Cleaned video demonstrate?
This video shows a Netalux laser removing 3/8 inch of accumulated pitch tar, creosote, and soot from an 80-year-old brick fireplace. The operator works at 415 mm standoff distance, making repeated passes over the most severely contaminated areas. Chemical treatment and sandblasting were ruled out due to surface sensitivity — laser cleaning restored the brick without contact or mortar joint damage.
How can this video help evaluate related applications?
This video provides a direct reference for deeply contaminated masonry scenarios — specifically pitch tar and creosote at residential scale. It confirms that 415 mm working distance controls both temperature and contamination spread on brick, and that thick deposits require multiple passes rather than a single slow sweep. Use it to calibrate expectations for fireplace, heritage masonry, and creosote removal jobs.
