Tuckpointing details that matter for Lake Davis/Greenwood homes
Joint notes from the family-owned masons who work in Lake Davis/Greenwood.
Letting moisture leave through the joints
Water that gets into a brick wall has to dry out somewhere. Preservation Brief 2 points out that mortar tighter than the brick pushes moisture, and whatever it carries, out through the brick instead, and what gets left behind in the units can harm them.
A joint that breathes gives moisture an easier route. For your Lake Davis/Greenwood chimney, the mortar is selected with that in mind, and we avoid dense patching products that seal the joints against drying. Dense, glossy patching compounds may look tidy at first, and they are the wrong choice for a brick chimney.
Type N mortar for most modern brick
Technical Note 46 names Type N as generally recommended for repointing modern brickwork. It is a moderate-strength, general-purpose mortar in the ASTM C270 system, and it suits many brick chimneys built with modern units.
When the brick and existing mortar on your Lake Davis/Greenwood chimney point to Type N, that is what we use, prehydrated and mixed to the right consistency. If the existing mortar turns out to be softer, we step down to a weaker type instead of forcing Type N into a wall that cannot take it.
New mortar in layers about 1/4 inch thick
Both Technical Note 46 and Preservation Brief 2 describe packing repointing mortar into the joint in layers, or lifts, of about 1/4 inch. A thick single fill shrinks more and can pull away from the brick as it hardens.
Our masons in Lake Davis/Greenwood fill each joint in thin, well-packed lifts. It takes several passes to reach the face, which is part of why careful repointing takes longer than a quick smear, and part of why it holds. Each lift is pressed firmly into place, and the final lift brings the joint out to its finished depth.

Before your chimney repointing in Lake Davis/Greenwood
If your question is not here, call our Lake Davis/Greenwood crew and ask.
How deep do you remove the old mortar?
To at least twice the width of the joint, generally about 3/4 inch on typical brick, and further wherever the mortar is still loose. We stop at sound mortar and keep the depth even across each area.
Why is sand collecting below my chimney?
Sand below a chimney often comes from mortar breaking down, as the binder weakens and the sand washes out. It is a sign some joints have softened, and an inspection shows which ones.
