Professional Building and Renovations works closely with Architect, Steve O'Neill, on all of our projects requiring building permits. Steve's many years of design knowledge and experience are an invaluable asset on our projects. We also work with Steve when completing structural repairs to homes that have been damaged by termites, see Journal of Light Construction April 2023 edition and article Repairing a Termite Damed House.
