You’ve noticed mortar loss. Now what? Here’s a practical guide to when you should call masonry contractors and what to expect when they arrive.

When to dial the pro

  1. You have multiple joints with missing mortar or spalling bricks.
  2. You notice water stains inside or on ceilings near the chimney.
  3. The chimney shows movement or large structural cracks.
  4. The crown or cap is visibly cracked and letting water in.
  5. You’re unsure how bad it is — professionals can quickly diagnose and prevent escalation.

What a solid masonry contractor will do

  1. Full inspection: They’ll assess the brick, mortar, crown, flashing, and flue.
  2. Explain options: Repointing (tuckpointing), crown repair, flashing replacement, or full rebuild if necessary.
  3. Match mortar: Use compatible mortar — matching historic mortar is especially important on older homes.
  4. Clean & finish: Proper tooling and cleaning so your chimney looks good and sheds water.
  5. Warranty & care: Clear terms on workmanship and maintenance advice.

Questions to ask before hiring

  1. Do you carry insurance and can you show proof?
  2. Can you provide references or before/after photos of similar tuckpointing work?
  3. What mortar mix will you use and why?
  4. How deep will you remove old mortar?
  5. Do you offer a written estimate and warranty?

Red flags to avoid

  1. Extremely low bids with vague scopes — you’ll likely pay later for shortcuts.
  2. No inspection or unwillingness to show references.
  3. Promises to use “just any cement” — wrong mortar can damage bricks over time.

Cost and timeline (what influences price)

Prices vary by region and the job’s complexity. Factors include the chimney height, extent of mortar failure, accessibility, and whether additional repairs (flashing, crown, or brick replacement) are needed. A surface patch might be a day’s work; larger jobs can take several days.

Tuckpointing near me in Chicago is one of those maintenance tasks that quietly saves you money and stress long term. If you want the job done right, trust reputable masonry contractors who inspect thoroughly and explain what they’ll do. Your chimney is a small, but crucial, piece of your home’s armor against weather — treat it accordingly.
