A masonry project—whether it's a brick chimney, stone patio, or foundation repair—requires skill, experience, and reliability that varies wildly between contractors. Hiring the wrong one can mean cracked mortar, water damage, or thousands wasted on rework. Here's how to compare masonry contractors with precision and confidence.
Verify Licensing and Insurance
Your first filter should be non-negotiable credentials. Every masonry contractor should carry a valid state or local masonry license (requirements vary by jurisdiction—check your county or state licensing board). Ask for proof and verify the license is current and in good standing.
Insurance matters equally. Request a Certificate of Insurance showing General Liability (minimum $1M coverage) and Workers' Compensation. Call the insurance provider to confirm it's active; don't rely solely on a document the contractor provides. If they're uninsured and someone gets hurt on your property, you're liable.
Check References and Reviews
Ask for at least three recent masonry projects—ideally from the last 12–18 months—with contact information. Call these references and ask specific questions: Did the work stay on schedule? Was cleanup thorough? Have any issues appeared since completion?
Cross-check online reviews on Google, Yelp, and Better Business Bureau. Look for patterns, not isolated complaints. One negative review in 50 five-star reviews is normal; multiple complaints about poor craftsmanship or communication are red flags. Pay special attention to comments about mortar quality, water sealing, and longevity.
Get Multiple Bids and Compare Details
Request written estimates from at least three contractors. A vague quote ("brick repair—$2,500") is useless; a good one breaks down labor, materials, and timeline.
Typical masonry costs range as follows:
- Brick or stone patios: $8–$25 per square foot
- Chimney repair/rebuilding: $1,500–$5,000+ depending on height and damage
- Foundation repair or repointing: $10–$30 per square foot
- Retaining walls: $20–$50 per square foot
Don't assume the cheapest bid is best. Compare what's included: Does the estimate specify mortar type (Type N, S, or O—each has different strength and flexibility)? Are materials premium or basic? Is site prep or debris removal included?
Assess Experience and Specialization
Masonry isn't one skill. A contractor skilled in ornamental brickwork may lack expertise in structural repointing. Ask how long they've been in business and how many jobs similar to yours they've completed. If your project is a stone veneer installation, you want someone with proven stone work—not just brick experience.
Inquire about their approach to challenging conditions. If you have drainage concerns or your home is older (pre-1950s masonry often uses different mortar), do they understand historical preservation standards? Inappropriate modern mortar can permanently damage old masonry.
Evaluate Communication and Professionalism
How quickly do they respond to inquiries? Do they answer questions thoroughly or brush you off? A contractor who takes time to explain the scope, timeline, and process upfront is more likely to deliver smooth execution.
On the first meeting, assess whether they walk your property carefully, take notes, and identify potential complications. Someone who spends 15 minutes and gives you a rough estimate isn't thinking through the details. A thorough assessment takes 30–45 minutes.
Confirm Timeline and Payment Terms
Get a written timeline with start and completion dates. Masonry timelines vary: a small brick repair might take 1–2 days; a large patio or chimney rebuild can span weeks. Weather delays are normal (mortar cures slowly in cold or wet conditions), so confirm how delays are handled.
Discuss payment structure upfront. Typical arrangements are 50% deposit, 50% upon completion—avoid contractors demanding 100% upfront. Never pay in cash; insist on checks or invoices for a paper trail.
Frequently Asked Questions
Q: How do I know if a contractor is doing mortar repointing correctly? Good mortar joints should be concave or "V"-shaped, packed firmly without voids, and the mortar color should match existing work. Ask the contractor to show you a mortar sample matching your existing masonry before work begins.
Q: What's the difference between brick sealing and proper mortar work? Mortar is the binding material between bricks; sealing protects the brick itself from moisture. Both matter—poor mortar allows water infiltration, while unsealed brick absorbs water, leading to spalling. A quality contractor addresses both.
Q: How long should masonry work last? Properly installed brick or stone typically lasts 50–100+ years; mortar repointing lasts 20–40 years depending on weather exposure and mortar type.
