5.0 Ann G. Valparaiso, IN

Our HOA worked with Grimes Exteriers and they exceeded our expectations. Greg worked with our insurance company and was instrumental in getting our Hail Damage Claim aporoved for our whole complex. His quote was competitive and he uses high quality materials. Greg was on site all day, every day and the job stuck to the timeline given. His workers were very pleasant, professional, and competent. The sites were cleaned every day. They did a great job. We would highly recommend Grimes Exteriers.

Greg and his company stand behind their work. They are local and not a storm chaser. They will be there!

5.0 Warren F. Chesterton, IN

I researched four roofing companies proposals and Greg Grimes Exteriors was by far the best. Since I am a senior citizen Greg also gave me a great deal to include gutter leaf guards. No more climbing an unsafe ladder for me to clean the gutters of leaves and debris. His crew was polite, on time and did and did a really great professional job. Upon completion the crew completely cleaned the entire area of nails, and other materials. I have never had a better experience with a construction contractor in my entire life. Keep up the good work, your the best.

Greg was very friendly, fair price and has a great crew of workers. They did my ranch home, detached garage and shed roof, pretty quick. Love it !

5.0 Amy T. Chesterton, IN

Greg helped us out tremendously after a very bad ice and water damage incident to our home. We were fortunate that we heard of him through a mutual friend. He is genuine and easy to work with. We will also be using him for our next upcoming project which will be siding.

Great work.

5.0 Alan S. Valparaiso, IN

We're very pleased with our new roof. Greg and his crew were a pleasure to work with. They were very punctual and got the job done in less than 2 days. We were also very pleased with the clean up job after the roof was finished. Would highly recommend this company.

5.0 Nancy H. Portage, IN

My experience with Grimes Exteriors was positive from start to finish. When Greg Grimes came to give me the estimate, he was so nice and easy to talk to. His was the third estimate that I had received and he could get my roof done much quicker than the other two companies for a better price. My roof was leaking so getting it done sooner rather than later was very important to me. After just talking with Greg for a short time the day I met with him, I felt very confident in my decision to hire his company for the job. One week later and my roof is replaced and everything went smoothly and I am a very satisfied customer. I will definitely recommend Greg and his crew to family and friends. I will also contact him for any other projects I may have in the future. I am so happy that I found this company. No problems whatsoever!!

5.0 Jeremy L. Wanatah, IN

Greg was professional and fast , I had 2 weeks to find a roofer and complete my roof or my insurance was going to cancel , got an install date within 24 hrs of contact , had roof done in 1.5 days and it was a hard roof multiple levels and layers of shingles and almost the whole roof needed new decking for an amazing price !!! They are doing my siding within the next 2 weeks because they saved me so much time and money we decided to have them side our house thanks Greg and crew

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.

  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
