I had a very poor experience with Preferred Garages and I recommend others to stay away from them. Below is just a few examples of the several issues I had: Poor communication: Once the contract was closed, Greg would not make himself available for phone calls. Instead, the only options to communicate with him were email and text. If I had multiple questions for him in the same message and he would only answer one, leaving the others unanswered. Multiple mistakes: There were multiple mistakes in the construction. For example, they put the door frame in the wrong place, which I had to correct them. This happened twice with two doors. Unprofessional language: When I brought up that the door frame was placed incorrectly, he blamed me for it, even though I had provided him exact diagrams. Not only that, he treated me using rude and unprofessional language. Lying about materials: An important part of this construction was to use sound proof insulation. However, Greg proceeded to install a cheaper material that was not sound proof. He claimed that the new material was just as good (which wasn't) and that the original material was not available, even though it was in stock at the nearest Home Depot and Lowes. While the building turned out OK in the end, the construction took 6 months to complete and took significant effort and frustration on my part. read more

Using this company to build my garage was one of the worst mistakes I've ever made in my life. The owners name is Greg Moss, beware of this contractor, he has been building garages for a long time and he is very smart. He knows how to work the system and you will have no leverage to hold him accountable for what he says he will do. He is a despicable person to work with and everything will be done his way even if that means you don't get what he said you would, or what you paid for. He is sometimes very good about returning phone calls but it doesn't matter because he will not address your concerns. He doesn't care. My project took 6 months and he never showed up to the job site even once, not once until the end and it was time to collect money. In regards to my project, he cut a lot of corners and pushed me around like I was garbage. He didn't provide a porta-potty for his subs, left all the trash and rotting garbage in my front yard for months which was so embarrassing to neighbors and killed my grass. The $30K driveway that they installed completely disintegrated in 16 months and he was willing to do nothing. I could tell you much, much, more. It won't matter to him because he has all the work he can get, but for your sake, run like hell from this dude. Please don't make the same mistake I made. TW read more

Over all would not advise to use these people the owner has a real attitude and like the other reviews terrible communications made a mess out of our sprinklers and just did you not read your contact we are not responsible for that all grading was god awful now will have to hire someone to redo it it also wanted 220 to be put in and all he wanted to was argue about it and said we didn't talk about he is just all about getting paid and does not care at all about the customer I would not be able to even give a one star. So sorry I went with him gave him over 100 thousand dollars for a just ok job. A 0 star rating read more

Horrible experience. Long delays, problems passing inspection, lack of communication, trash left for weeks on end. Worst experience I have ever had with a contractor. read more

Overall, cannot recommend this company. Then end product looks nice and is functional, which is the only reason it gets any stars. Everything else was pretty terrible. Communication especially was awful. I would request a status update and the response was always something like "x is next. Maybe next week." Or "not sure. waiting on y." I signed the contract in August. Construction started in September. Estimated 6-8 weeks for construction. Wasn't finished until Christmas, and I'm actually still waiting for the last of the excess materials to get picked up and it's February. The majority of it seemed to be finished in about 2 weeks. From there it was anyone's guess when or if anyone would show up to do work. Weeks would go by with no work, no communication, and then suddenly one day there would be a bunch of people in my backyard with no warning-no text, no knock on my door to alert me of their presence. They'd work for a day or two. Make a giant mess of my backyard - Mud everywhere, garbage everywhere - and then disappear again for weeks. I had to clean up so much trash, food wrappers, beverage containers, empty cigarette boxes. They also just helped themselves with use of my things and then left them wherever when they were finished. Most notably was the time I found my hose connected to the house on a day it was below freezing with a hard freeze expected that night and weekend. I was livid since I had purposefully put away the hose the day before, since I knew it was supposed to freeze and I didn't want any damage on my home. They also tore up my irrigation system to build the garage and just left sprinkler parts laying around and cut off irrigation tubes sticking out of the ground or buried wherever. When I complained about this and requested they fix it, the response was just "we don't do landscaping." So apparently they can destroy your property to get the build finished and not have to do anything to make it right because it's "not their job." I can't see how it could be that hard to cap the ends of the tubes they cut and not bury them indiscriminately, so I could at least still have a functional irrigation system and not have to worry about water leaking god knows where underground. The grand finale of this all is when I finally was able to start parking in the garage, it was an absolute mess in there. Mud was caked everywhere all over the floor. There was sawdust and rogue nails and screws all over. There were excess materials and empty boxes from the electrical work. It took me over two hours to clean it up so I could pull my car in. The fact that they considered this a "finished job" was laughable. read more

If it wasn't for Preferred Garages (Greg), I don't think I would have been able to do this garage. He worked with the city to get my garage approved and it wasn't an easy process. He also worked tirelessly with the building inspectors that weren't competent enough to know the actual guidelines. I made a few changes along the way and he had no issues with that and actually was quite helpful. Not only did he communicate with me during the process, the garage work was very well done. I would recommend them. read more

I do not recommend this company. The owner Greg Moss does not communicate any status. I signed the contract on May 30. He said the garage would be completed and driveway poured in 4 weeks. 6 weeks max. The driveway was finally poured on October 25. It took him 21 weeks to build a simple garage with no work done on the inside. I would text him asking when they would be showing up and he always responded with maybe next week. The garage permit failed during the permit application process because of lack or engineering papers and also failed the framing inspection. Thankful for the Thornton City inspectors to catch the questionable work by this company. The garage was complete but needed to be shingled. Rain was forecast for the next day so I called Greg to see when they were going to shingle. He said he didn't know. The shingles were not even ordered yet. I asked if he could put the tar paper down to protect the decking. Greg told me that rain does not hurt the wood. I bought tarps to protect the decking. Very hard to work with, do not use Preferred Garages. read more
