GSM Builders is the worst that can happen to your backyard renovation product. Nearly 19 months this company has been struggling to finish our pool and pavers around. At first it was only time it was upsetting us, later horrible attitude of the owners Greg. On questions when he is coming to finish we would get replies: "when we are done with other customers, you are not our only customer; he used F... word multiple times. Also no replies were his favorite thing to do. After the attitude came in extra costs: we were told to proceed with work they need 1. 6K to put retaining wall because they built the pool way too high compare to the ground. 2. Extra pay to bring electrical from the inside to outside electrical pool panel extra cost too. 3 to relocate sewer line or equipment would go on top of it. We were told about that right before equipment to be installed, just to delay process even more. After extra costs and finally finishing the pool, came in problems with finished pool. Until last second we were hoping that things will be fixed but it is not happening. 1. Firstly Pavers on back porch were put in on top of the old brick pavers and now color new pavers. GSM told us that our contract did not include removing pavers. May be it is not specified but finished product needs to look good. Now we have to pay to remover new paver, old paver and lay it again. It should have been done right first time around even if it is extra cost. 2. At signing contract we were told we will have everything automatic so we can turn on and off from the phone all pool applications. As appears, we need to buy and install extra valves to make it work...:) 3. Heater has been leaking some water from day 1. GSM kept saying it is condensation. We finally called warranty. Warranty Company came out and told us it was not set up correctly. 4. Plaster in the spa is horrible, so rough you can barely sit in it. 5. Lastly GSM left without explaining anything about the pool or equipment, now saying they do not have access to our system via aqualink while we have not changed anything in set up. Regardless how is that connected to explaining us about equipment? The owner is the master of excuses, I am sure he will write a big letter here explaining what happened, making up things like we did not pay that is why delays, or he goes by the contract when we ask to fix ugly pavers. Excuses, excuses that is the only thing he is good at. Regarding payment, the only payment we did not pay on request, the same day is last 10% deposit. We were so scared we will never see gsm again after payment. After couple days of asking to show us some proceeding in work before last payment, we had to pay every last penny of the contract anyway two month before final inspection passed. The owner basically threatened to not proceed until he gets all the money. We never thought that any contractor can be this bad!!! read more
