  The experience was not desirable. I was told my unit was a throwaway unit and was not worth working on. He said they couldn’t get the parts, but when I googled for parts there were parts for my unit. This is the problem I have with this situation, I should have been told that the company only fixes certain units and that my was not a unit that they work on. I would have said thanks, and moved on, but because I was not told that, I wasted my money on service man that did not solve my problem. I think the company needs to be honest with there customer and let them know what they will do, so it not a waste of time and money for there client. Not knowing this I think I should be reimbursed for the money I spent.

  Alan, we are very sorry you feel this way. We actually do not work on units installed by a non-licensed contractor due to liability. Not only that but the unit meaning the air conditioner was purchased online therefore, the parts don’t have warranty either. We apologize, but under the circumstances, we’re just unable to help you. Thanks.

  My husband initially reached out to Grandmark after noticing we had 3 cracked tiles on our roof. They came out quickly and were able to assess the situation and give us a fair quote. We felt good about moving forward with Grandmark as the …

  Eric came to my business and found the problem in 10 seconds. He then explained to me that I should use an expensive capacitor so it doesn’t go out. He charged me $849 for 30 minutes when I looked up the capacitor online it was $60, he told me that I’m actually paying for his schooling and for the warranty but yet he tried to sell me a “cheap” capacitor for $400 in which the cost of it was $39 . As a business owner, I work hard for what I have and I feel like this company stole from me and my family took advantage of my ignorance

  George we apologize for the way you feel. Sadly people not always understand what the project takes and pricing can be confusing. Allow me to explain. First - the parts you find online are not the same parts we install. Anything you buy #1 used to be illegal and 2 have no warranty. Second - we have to offer you warranty for at least 1 year so if we need to come back we are at a loss. Any transaction where one party loses is a bad deal. Third - our expert technician’s are able to diagnose quick because of their expertise. If we take 3 hours to diagnose would you pay more? You would say we are inefficient Eric recommended a premium part to prevent future damage to the AC compressor is all. He advised on what he knows is best for you. Sadly and understandable pricing became an issue. Homeowners sometimes also forget that any company has a cost to operate as well.

  From the start it was just short of a nightmare. The front office was the low point. Scheduling a date, nobody showed up, no calls to make me aware, nobody the next day too, finally when I got back with them , I was hung up on by two different people, when they got back with me a couple days later , I got weak excuses. The estimate guy was ok but gave me a price that was $680. Less than what I ended up paying, due to him not being able to see the dry rot. The laborers came a week or more later, four guys who spoke little or no English, I believe they were the best part of this deal. Took two days for the repairs . I was told I would get a cash discount, I didn’t get it. I paid $99. To the estimate guy , it was supposed to be deducted from the bill, the bill did not have the deduction but the last guy who brought the bill and did a walk thru with me took care of that, he was a good guy to deal with. That was today, I won’t know if the work they did has helped until it rains again. Personally, I would never deal with them again. The work may or may not be good but the office was not fun to deal with.

  Dear Ron, Thank you for bringing your concerns to our attention. We would like to clarify the facts surrounding your recent project with us. According to our records, the initial call with Theo was made on March 6, 2023, lasting 7 minutes and 6 seconds. On March 22, Antonio attempted to contact you but was unable to reach you, leaving a 55-second voicemail. The following day, on March 23, the team discovered dry rot and Tim called to notify you and adjust the projected price. On February 24, Antonio confirmed that the team would deliver a hard copy of the invoice and do a final walk-through with you. The call lasted 38 seconds. On March 25 at 10:51 AM, Angel called to notify you of the time he would be hand-delivering the requested hard copy, and you agreed. The call lasted 43 seconds. As you paid with cash, we cannot refund the source. However, we have credited your invoice with the amount and also provided a $112 senior discount. A final walk-through was completed on Saturday, March 25, at 1:48 PM. We appreciate your feedback, and while we are unsure what caused your dissatisfaction, we are actively looking into what can be done to prevent similar issues in the future. We take pride in our communication and will strive to ensure that every detail is communicated clearly. We also want to assure you that we do not regret informing you of the dry rot. We believe that doing the right thing is always in our clients' best interest, and we strive to maintain integrity in all our dealings. Thank you for your business, and please let us know if there is anything else we can do to address your concerns. Sincerely, Grandmark Service Company

  I called grandmark to have my roof scrubbed, and they sent the nicest Young man out to do the job,his name was Joe he was polite courteous good looking young man very hard-working, because as I watched him, I realized that the job was not an easy job for anyone to do.

  From start (David-Quote) to finish (Joe and Team) they kept me informed throughout the process at my home in Ripon. Photos and videos of the job as it was getting done. Fair quote as well. Highly recommend Grandmark roofing. Even my neighbors told me how impressed they were at the work preformed. Mica running the office was great to deal with as well. I definitely made the right choice. Thanks again

  Good work, done on time and even did a little more of the gutter guard than what was quoted. Only issue was communication with the techs…but, the estimator (Dave) was easy to get a hold of and could help to answer any questions. Will use Grandmark in the future.
