Masonry Repointing & Tuckpointing

Rebuild failing mortar joints and stop water in its tracks.

Mortar is sacrificial — it wears out long before brick does. Once joints are recessed, cracked or sandy, water gets behind the face of the chimney and the structure starts to move. Repointing grinds out failed mortar and replaces it with a matched mix, restoring both weather resistance and strength.

Before any work

Need a Repair? Free Inspection Before We Start the Work

We look first, photograph what we find, explain the visible condition and the options, then price the work. You decide before anything begins.

Applies to the initial evaluation before applicable repair, restoration, fireplace and masonry work. Dedicated inspections — real-estate transactions and specialized Level 2 or Level 3 inspections — are separate priced services.

What we do

  • Grinding out and repointing deteriorated joints
  • Tuckpointing for appearance-matched joint lines

  • Mortar color and texture matching

  • Step and shoulder masonry repair

Signs you need this

  • • Mortar you can scrape out with a screwdriver

Our process

  1. Step 1

    Assess

    We check joint depth, mortar hardness and how much of the stack is affected.

  2. Step 2

    Match

    Mortar is matched for strength, color and joint profile — hard modern mix on soft brick causes damage.

  3. Step 3

    Repoint

    Failed joints are cut out to depth and repacked, not smeared over.

  4. Step 4

    Seal

    Optional waterproofing keeps water out without trapping moisture inside the brick.

Repointing FAQs

How do I know if my chimney needs repointing?
If you can scratch mortar out with a key or see joints recessed more than about a quarter inch, it is time.
Do you repoint the whole chimney or just bad spots?
We repoint what has failed. Spot repointing is fine when deterioration is localized; widespread failure needs the full stack.
