An example of water penetrating the "3/8in seal" that is supposedly impenetrable.
Dawn F.

DO NOT TRUST OR USE THIS COMPANY! They sold us on their outdoor sealant by telling us it would take care of our problem of sealing our sand stone flagstone that covers the large pool area and patio. Our issue was that water was deteriorating the stone and bits of sand were getting all over the pool and spa bottoms. This probably wasn't a great choice of rock to use in a pool area but we bought the house as it was and were trying to find a solution without having to tear it all up and replace it. DENNY at SEAL TEAM ONE guaranteed us that his product would seal our decking and protect it from further deterioration. As we used the pool after the product was applied last Summer, we realized the sealant wasn't at all doing the job. We called back to see if we needed another coating or if something was done incorrectly during the application because he guaranteed us his product would work. It was then that he said, "Well, yes you're still having deterioration because that flagstone got waterlogged long ago and nothing is going to really seal it." Whaaaa??!! "Then why would you take our $5,000 and tell us it will work?" we asked. He then told us that his sealant is only guaranteed to protect against stains. ....stains? We never had a problem with stains. The words "stains, spills, discolor, accidents, blemishes...you name it, were NEVER MENTIONED BY EITHER PARTY. We DID NOT need stain protection. We are still trying to get our money back. He will no longer return my calls. DO NOT USE THEM!

FMJ Concrete did an amazing job on our yard! They paved a large side yard, removed pavers to…read moreinstall a sidewalk path, knocked out a brick step and replaced it with a concrete step, added a short fence with a gate, and replaced the support posts for our wooden deck - including adding concrete footers. They also built a flat bad for the air conditioner and were easy to coordinate around with the AC vendor for disconnect/reconnect. Filiberto was friendly to work with and provided a reasonable quote for the work. He gave an itemized quote so we were able to decide what portions of our goal we could achieve with the funding we had available. The final cost exactly matched the quote I received. The team showed up on-time. They were very friendly and required no supervision. The project was cleaned up perfectly when complete. We requested a quote on November 13, began the project on December 10 and did a final walk through on December 30. That was probably a week extended due to delays (with my AC vendor) in moving the AC so the concrete could be poured and the Christmas holiday. I could not be more ecstatic with the final product. We will definitely be using FMJ Concrete again in the future and I highly recommend you do as well.
