Costas Construction is okay for demolition. Stay away otherwise. He is not the contractor to hire for finish work. It cost me thousands to correct his mistakes.

Costas Contracting did an excellent job installing new windows, new roof and multiple repairs needed in two of my properties. It was done timidly and a good clean up after they were done.
Thanks
