Everything was done as agreed upon. They arrived on time. Cut and removed the concrete, dug out the dirt and clay, installed the shelter, filled around it with concrete, cleaned up after.. This was all done in about 4 hours. They did not ask for payment until the job was done. They are very professional. We highly recommend them.You can't go wrong with this company.

They did a great job and I would recommend them. They were very thorough and cleaned up very well. There was mud and dirt everywhere and they cleaned it all up. We will use them in the future.

They go through the garage floor and put it underground. They were very clean and punctual. They were very professional and power washed everything before and after. It was perfect. We have recommended them and would definitely use them again.

They arrived on time and completed the work in a timely manner, Finishing the job when they said they would. They were very professional and and I highly recommend them.

This company scheduled an appointment to install my shelter at 7:00n AM on 5/27/2011. When they didn't show up I called and was told that they would check on what the problem was. When they finally called they said they could'nt get to it until the following month. If you are looking for professionals that do what they say they will do then these guys are not for you.

My neighbor had one put in a couple of years ago and that's who they went with. I looked at different companies and the reason why I liked Ground Zero is because they use the concrete truck to back fill around the shelter and the ground instead of just putting the dirt back. They scoop out all the dirt and then they put in the middle shelter into the ground. It is really cold and it was my Valentines Day present and that I live in a cooler city so that's important. (Hope I don't have to use that) They said they'll be here at 7 and they were here at 7 on the dot. They started digging and by 7 that night they were done. They worked really hard to get it in quickly and efficiently. There was no drama. Everything was fine. They kept me a deal on a winter sale. They were having a winter sale and I bought it. It's a family owned and operated business out of Oklahoma so that's important in supporting local. They were just really nice. I would use them again in the future if need be.

They subcontracted the gutters out. They were very thorough and the guy worked with us with the insurance claim. He did a lot of the footwork and we were very happy. This was the second time we have used them.

Richard and his assistant showed up at precisely the correct time. Although I failed to remember the correct day and had not cleaned out the 3rd bay of our garage Richard and his assistant helped me move everything. This caused them a delay in time and when the concrete truck arrived he had to wait about 45 minutes before he could start pouring. This was at a cost of $2.00 per minute. GroundZero absorbed this cost even though it was due to me not having the garage cleaned out. Richard had estimated that the job would take 4 hours. It took 4 1/2 hours due again to my fault. When the job was completed my garage floor and driveway was cleaner than it was before the job. The shelter itself is by far the best construction of any others we researched. All seams are double welded inside and out. The door is self locking and has (2) hand holds that are covered within for further protection. The shelter has been tested by the Wind Science and Engineering Research Center at Texas Tech University, and found to exceed FEMA standards. The company is family owned and operated. Richard who is President of the company actually did the installation. I could not be more satisfied.
