Not All Stone Restoration Companies Are Equal
Hiring the wrong stone restoration company can result in damaged surfaces, wasted money, and frustration. Natural stone requires specialized knowledge and equipment — general cleaners, handymen, and tile contractors rarely have the training to work with marble, granite, terrazzo, and limestone. Here are the ten questions you should ask before hiring anyone.
1. How Long Have You Been Specializing in Stone Restoration?
Stone restoration is a specialized trade that takes years to master. Look for companies with at least 5–10 years of dedicated stone restoration experience — not general cleaning companies that added stone work to their list of services.
2. Are You Licensed, Bonded, and Insured?
Verify that the company carries general liability insurance, workers’ compensation coverage, and any required state or local licenses. Ask for certificates of insurance and verify they are current.
3. Can You Show Me Before-and-After Photos of Similar Projects?
A reputable company maintains a portfolio of completed work. Look for projects similar to yours — the same type of stone, the same type of damage, and the same type of setting (residential vs. commercial).
4. What Equipment and Products Do You Use?
Professional stone restoration requires diamond tooling (not sandpaper), planetary grinders or hand polishers, commercial-grade sealers, and specialized stain removal products. Companies using consumer-grade products or improvised equipment are unlikely to deliver professional results.
5. Do You Provide a Written Estimate and Scope of Work?
A professional estimate should detail exactly what work will be performed, what products will be used, the timeline, and the total cost. Vague estimates lead to misunderstandings and unexpected charges.
6. What Is Your Warranty or Guarantee?
Ask about the company’s warranty on their work. Reputable companies stand behind their results and will return to address any issues within a reasonable warranty period.
7. Can You Provide References?
Ask for references from recent customers with similar projects. Contact those references and ask about the quality of work, professionalism, timeliness, and whether they would hire the company again.
8. How Do You Handle Unexpected Issues?
Stone restoration sometimes uncovers problems that were not visible during the initial assessment — hidden cracks, previous repair work, or moisture issues. Ask how the company handles these situations and whether they communicate changes before proceeding.
9. What Is Your Availability and Scheduling Process?
Professional stone restoration companies are often booked weeks in advance. Ask about lead times, scheduling flexibility, and whether the company can accommodate your preferred timing — especially if you need after-hours or weekend work.
10. Do You Offer Ongoing Maintenance Programs?
Stone restoration is not a one-time event. The best companies offer maintenance programs to keep your stone looking great between major restoration visits. Ask about maintenance schedules, pricing, and what each visit includes.
Red Flags to Watch For
- No physical business address or only a P.O. box
- No insurance certificates available
- Pressure to commit immediately or unusually low pricing
- No portfolio of previous work
- Inability to identify your stone type or explain the restoration process
- Cash-only payment requirements
