Repointing and tuckpointing work is expensive, invasive, and directly affects your home's structural integrity—so hiring the wrong person can be costly. Before you sign a contract, you need clear answers about materials, scope, warranty, and the specialist's experience with your specific masonry type. Here's what to ask.
What Type of Mortar Will You Use?
This is the most critical question. Modern mortar isn't one-size-fits-all, and using the wrong strength can trap moisture or cause spalling. Ask your specialist:
- What mortar type do they recommend (Type N, O, S, or M)?
- Do they know the original mortar composition of your masonry?
- Will they test the existing mortar before specifying a replacement?
The answer reveals whether they're doing competent work or just grabbing a bag off the shelf. Type O is softer and breathable—correct for 100-year-old brick. Type N is standard for most modern work. Type S and M are stronger but can damage older masonry. A specialist who tests first and explains their choice is worth the investment.
How Long Will the Work Take, and What's Your Weather Policy?
Repointing can't happen in freezing temperatures or heavy rain. A vague timeline is a red flag.
Ask for:
- A realistic start and completion date
- Whether they pause work in winter or rainy stretches
- How they protect freshly pointed joints
- What happens if the timeline extends
A two-story brick house typically takes 3–6 weeks depending on mortar damage, square footage, and crew size. If someone promises it in two weeks, they're either understaffed or overcommitted.
What's Included in Your Estimate and Warranty?
Get everything in writing. Repointing costs range from $15–$30 per square foot of wall surface (sometimes higher for complex work), but specifications vary wildly. Your estimate should detail:
- Linear feet of joints to be repointed
- Depth of mortar removal (typically 2.5–3 times the joint width)
- Cleanup and debris removal
- Scaffolding or lift rental costs
- Paint, caulk, or sealant application (if included)
- Warranty period (usually 5–10 years for labor, longer for materials)
Don't accept verbal assurances. A written warranty that covers re-raking or failed joints protects both parties and shows the specialist stands behind their work.
Do You Have Experience With My Specific Masonry?
Brick, stone, granite, and adobe all require different approaches. A specialist skilled in limestone repointing may wreck a sandstone facade.
Ask:
- What types of masonry have you repointed in the past five years?
- Can you provide references for similar projects?
- Have you worked on buildings from my era (Victorian, mid-century, etc.)?
Request at least three recent references and actually call them. Ask if the joints are holding up, if the specialist was punctual, and if the finish color matches.
Will You Remove Old Mortar by Hand or Grinder?
Hand-raking is slower and more expensive but safer for softer masonry. Grinding is faster but generates dust and can damage brick edges if the operator isn't skilled.
- For historic or delicate masonry: hand-raking only.
- For modern brick: grinding is acceptable if the specialist shows control.
- Hybrid approach: some hand work in sensitive areas, grinding elsewhere.
A specialist who doesn't discuss this hasn't thought through your specific project.
What Insurance and Licenses Do You Carry?
Verify:
- Current general liability insurance (ask for a certificate of insurance)
- Workers' compensation coverage
- State or local contractor licensing (requirements vary)
Call your state's licensing board directly to confirm they're registered and check for complaints. This takes five minutes and prevents hiring someone who'll disappear mid-project.
Do You Use Sealant, and If So, Why?
Sealants are controversial in restoration circles. Some specialists recommend them for protection; purists argue breathable mortar needs no sealant. Ask what they recommend and why, and get it in writing.
Frequently Asked Questions
Q: How do I know if my mortar really needs repointing? A: Look for mortar that crumbles easily when you scrape it with a knife, visible gaps wider than ¼ inch, or mortar receding below the brick surface. If water enters visibly or you see efflorescence (white salt deposits), repointing is urgent.
Q: Can I DIY small repointing sections? A: Minor tuckpointing on a single wall is possible for patient homeowners, but getting mortar color, depth, and compaction right is hard—and mistakes are permanent and visible. Professional work is worth the cost for anything beyond a small experimental area.
Q: How much does a typical repointing job cost? A: A 1,500-square-foot single-story home runs $5,000–$12,000; larger homes or multi-story work scales up significantly. Complex stone work or removing very old hard mortar pushes prices higher.
