I agree. They touted how quick the install would be and how they only work one job at a time. That was not the truth. Mine was started in April and I was told I'd be swimming that spring. The job took until September after much additional invoicing for excavating extras. I was very patient with them in hopes the job would get done right. Well, they never properly leveled my pool. I have a pool/spa combo and it does not flow correctly because of it. I have to improvise the water level to make it work correctly. The shallow deck built into my pool shell as well as the spa actually were allowed to sink low. When I was given the word that the pool was finished I gave the ok to the concrete company to start pouring the concrete around it. Once I started walking around the patio after it dried I noticed how badly off kilter the pool shell was. When I pointed it out to the contractor his response was I should have told him before I allowed the concrete company to do their thing. I WAS TOLD THE POOL WAS FINISHED!! They are supposed to be the experts. Now if I want it fixed I have to rip up my stamped concrete patio which will cost a fortune. Also, they did not take the time and care to prepare the ground properly before setting the filter equipment. Shortly after, the plastic platforms they used have sunken into the ground and all runoff water in that area goes toward my equipment. The ground should have at least been tamped down solid. If you use Diamond Pools be prepared to supervise the job very very closely if you want it done right. In my case they did not take it upon themselves to do so. Needless to say I wasn't asked to fill out one of those customer satisfaction surveys that they bring to all their sales pitches.
