Bill Block Masonry repairs chimneys, builds retaining walls, and restores fireplaces and brickwork across northern Oakland & southern Genesee County. One expert mason, a small crew, no subcontractors.
From a cracked chimney crown to a full retaining wall, every job gets the same attention to detail — because Bill's the one laying the brick, not just running the crew.
Crown repair, tuckpointing, flashing, and full rebuilds for chimneys showing cracks, leaks, or leaning.
Block and stone retaining walls built to handle Michigan freeze-thaw cycles without shifting or bowing.
Indoor and outdoor fireplace builds, rebuilds, and firebox repairs using the right materials for real heat.
Repointing crumbling mortar joints, replacing spalled brick, and matching existing brickwork on additions.
Natural stone and manufactured veneer for porches, entryways, and accent walls.
Not sure what's wrong? Bill will come look, tell you straight what it needs, and quote it on the spot.

No dispatched subcontractors, no rotating crews. It's Bill and one or two helpers, start to finish — so the mason who quoted your job is the one who lays every course of brick.
