Sent a request to Potomac Garage Solutions as other neighbors had used them previously. Jeff followed up with a phone call indicating they could provide overhead storage for 2 or 3 units that are electrical operated. He indicated he knew the houses and the units would fit with no issues. The cost of two units would be in total 1500.00. He asked for my CC # for half of the cost and the balance would be handled upon installation and adjusted if additional units could be installed. A date was set and they arrived when scheduled. I was not really informed of what the actual units that were being installed were. It turned out to be like the ones my neighbors had installed. The guys delivered two unit and started taking them out of the box. I inquired about the third unit and the guys were not aware of there being a third unit. They said they had only brought two units. When they were putting together the second unit, it was discovered that parts were missing from the box they brought. I did see them bring in the new box and unpack it so it was not a previously opened box. They indicated they would have to come back once they had the missing parts. The guy said they would be back the next day. So they installed the first unit and part of the second one. The next day I waited and finally sent a text to Jeff asking where they were as the time and come and gone and still no installers. I also was waiting here just for this purpose and put my other errands on hold. He indicated they would not be there the next day and they had to order the parts. This should have been my que that something was not right. I thought a company that sells and installs garage storage units would have an inventory of the units they could just pull another one off the shelf and install it right away. When I informed him the guy told me he would be here the next day, he indicated that he should not have told me that. He said they would call me when the unit was received by them. It was another two weeks before I received a text indicating the parts had arrived and when would I be available to have them install it. I also inquired about a smaller unit as the larger unit was not able to be installed due to its size. He said for the smaller unit it would be 350.00. I said 325.00 and he said the price was 350.00. I said ok, but was not happy and to go ahead with that. The day came and the guys showed up to finish the second unit and install the third unit. But they had to make adjustments on the third smaller unit for the cable. The one guy left and went to Home Depot to get some parts/tools to shorten the cable as it was set for the larger units. Again, a que that this was not the way it should be. He was gone for over 1 1/2 hours and the other two guys waited in my garage for him to return and they had nothing to do. When he finally came back, I asked about another unit and texted Jeff regarding it and he indicated the price for a fourth unit would be 500.00. I said what about the 350.00. He indicated that was only for that third unit and not for a fourth unit. They finally got the units installed and my account was charged for the three units of 1500.00. plus 350.00. I inquired about getting the manuals for the unis and the invoice for the job performed. Jeff never has produced either of those after my texting him twice. I did find out the units if I were to purchase them from Home Depot would have cost me in total without the installation of 689.00. So either I could install it myself or get someone, but really don't think it would have cost me 1161.00 which is the difference just for the installation. Lesson learned by me. I also had in issue with the hooks that attach the cables to the platforms came open as I was raising the unit to the ceiling, it snapped and the platform almost fell. I am glad I was there as it was happening and was able to keep things from falling and the unit was not high off the floor. I had to go to my local hardware store and purchase additional hooks and I double hooked all of the cables on all three platforms so as to not worry if the platforms would fall onto the cars or the garage door if it were opened. That cost me about 60.00 for steel hooks. I text Jeff about my having to do this and no response from Jeff. These hooks were what came with unit I will say that. The platforms indicate they can hold up to 200lbs for the larger 6' x 3' units and 100lbs. for the 2' x 3' unit. I did not have that much weight so the hooks should not have snapped open. I do like the units and the fact that I can raise and lower them without getting upon the ladder, but if I had read the reviews of others before, I would never had used Potomac Garage Solutions. I am afraid that if I need service in the future, they would not be able to provide the service nor am I able to register the units for warranty as I do not have an invoice to provide for verification. Again lesson learned. Read reviews of companies before have a job done. I was asked by my neighbors who were interested in having their garage done, but I said to go with someone else.
