5.0 Raye T. Northbrook, IL

As busy as they are they fit me into their schedule as I was in time crunch (house guests). Great communication, professional, clean, on time. All around FANTASTIC!

5.0 Karen G. Northville, MI

It has been 18 months since this company replaced 3 cracked tiles in our 18 year old kitchen floor and painted the grout throughout the kitchen/dining area and it's still looking great! Very happy with the decision to go with the epoxy grout paint/sealer as it means no more scrubbing the grout to get it to look clean, it just always looks uniformly clean now.

5.0 Kelly M. Macomb, MI

Maxwell was professional and did an outstanding job repairing, cleaning and sealing my bathroom tiles. It looks like new.

5.0 George S. Rochester, MI

We were very happy with the professional service of Calvin and Maxwell. They were prompt, courteous, did an excellent job on our three bathrooms including grinding out and replacing the grout in our master bathroom. They left the bathrooms spotless. Highly recommended.

5.0 Sharon L. Pontiac, MI

Professional, on time dependable . Effectively communicated understanding of what service we needed. Followed up quickly when we asked him when he could do another project.

5.0 Dawn C. Clarkston, MI

Diamond Grout did an amazing job on our 20 year old master bath shower (floor and walls). It looks new!!

5.0 Michelle B. Bloomfield Hills, MI

My master bathroom is all porcelain tile, which includes the shower, the shower ceiling, the bathroom floor, my countertop, and one bathroom wall. Diamond Grout came out to 1) clean all the grout, 2) repair damaged and cracked grout, and 3) paint all the grout with an epoxy sealer. It was a 2.5-day job. They did great work - my bathroom looks brand new. I cannot believe how dingy and grimy the grout was before. Calvin the owner is very nice and knowledgeable about his business. There were a few bumps along the way, but they were handled professionally. And honestly, is there ever a home improvement project without problems? No way! A few days after my job was done, I noticed an area that needed a touch-up. Calvin was out within a week to do the touch-up. I really recommend this company, and I would call them again for future projects.

5.0 Kayla C. Auburn Hills, MI

Diamond Grout was very professional and provided to excellent service. I had then come out and clean and epoxy seals the grout and tile in my bathroom. It looks brand new! I would highly recommend this company.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
