Preservation Standard
Early twentieth-century Washington rowhouses rely on soft sand-lime mortar designed to breathe and flex. Using aggressive wire heads or rigid industrial scrapers in these delicate flues scores the brick surfaces and invites draft leaks.
Our technicians employ gentle rotary nylon whips and low-impact rotary cleaners that strip corrosive glazed creosote without compromising historical masonry joints or degrading internal clay tile assemblies.
Our Guarantee
Every flue diagnostic begins with three layers of pristine canvas. We guarantee zero airborne ash and leave your living room cleaner than we found it.
