Our approach to chimney masonry in Alderene Park
Brick industry guidance and the building code, applied to chimney repairs in Alderene Park.
Mortar chosen for a chimney's exposure
ASTM C270 sorts masonry mortar into types by strength and makeup. For chimneys above grade, the Brick Industry Association's mortar guide recommends Type N, with Type S as the alternate, and it advises choosing the lowest strength that still meets the job's needs.
A chimney stands out in the weather on every side, so the mix has to handle repeated wetting and drying while staying compatible with the brick around it. We name the mortar type on your estimate so you know what is going into the joints and why it suits your chimney. If the existing mortar is unusual, we say so and explain how that changes the choice.
Masonry where the chimney meets the roof
Flashing at the roofline is usually tucked into a mortar joint or a slot cut in the brick. When that joint crumbles, the metal loosens and water runs behind it into the chimney, the framing and sometimes the ceiling below.
Masonry work at the roofline is planned together with the flashing, so a sound joint is ready to receive the counterflashing and the roof is protected while we work. If a roofer is also on the job, we agree on who does which part and in what order. Nothing is left open between trades, and each piece of the work appears on the estimate.
Removing old patches and smeared sealant
Many chimneys carry earlier repairs: roofing cement smeared over joints, caulk pushed into cracks, or a skim of mortar spread across the brick faces. These patches often trap water behind them and hide how far the damage has actually gone.
Before repairing, we remove failed patch material from the area being worked on so the masonry underneath can be judged properly. That sometimes changes the scope, and if it does, we stop and explain the change before going further. Nothing is added to your bill without your approval, and the reason for any change is written down.
