We purchased a new house from Seal Harbor and would not wish the same experience on anyone. Almost immediately after we signed a purchase and sale agreement and paid them a substantial deposit, they proceeded to repeatedly break the terms of the contract and their policies in too many ways to list here. In response to our attempts to get them to respect our agreements, they would send us hostile emails full of falsehoods and nonsense.
Seal Harbor attempted to force us to close on the property after giving us improper documentation that was in plain violation of our contract. When we refused, they tried - with no justification - to coerce us into paying an additional $15,000 cash deposit. Less than two business days before closing, they produced a completely inaccurate "final change order" claiming that we owed them over $11,000, to be paid before closing. That was after assuring us by email three weeks prior that we would probably (in their words) "be receiving a credit, not a bill," and after months of us trying to get a timely accounting of credits and debits, which they should have provided according to their policies.
Aside from their dishonest and deceptive business practices, they are disorganized and inept at running construction projects. We had to intervene many times to ensure the construction would meet the agreed specifications, and were still not fully successful in doing so. Any time estimates they provided were complete fiction.
Seal Harbor has remained true to character after closing: they tried to weasel out of a clear-cut warranty claim by making easily disproved excuses, then said they would send someone to fix the problem. After multiple delays and no-shows, they stopped responding to our emails until we initiated a formal complaint.
Our experience with Seal Harbor is far from unique. If you - for whatever reason - decide to take your chances with them, make sure to do some extra due diligence and speak to a few of their recent customers.
