Mandeville’s housing ranges from historic properties in Old Mandeville near the lakefront to substantial custom homes in the subdivisions along Highway 22. Lakefront properties require specific renovation consideration around moisture management and site conditions. Newer subdivision homes offer conventional layouts with premium finish potential. We work throughout all of Mandeville’s housing contexts with experience in each and a consistent commitment to quality.

Yes. Whole home renovations are one of our primary services in Mandeville and throughout St. Tammany Parish. We manage complete home transformations from planning through final walkthrough, handling all trades, permitting, and project coordination under one roof. Our approach starts with a thorough assessment of every room and system before we write the scope.
Most whole home renovations in Mandeville take between three and six months depending on scope, the condition of existing systems, and whether the project involves structural changes or significant plumbing and electrical work. Projects that involve phased occupancy — where the homeowner stays in the home during renovation — often take longer than full vacate renovations. We provide a realistic schedule with every estimate.
Whole home renovation costs in Mandeville vary significantly based on the size of the home, the condition of existing systems, the quality of materials selected, and the extent of layout changes involved. A basic cosmetic update across all rooms costs far less than a full gut renovation that includes new plumbing, electrical, HVAC, and high-end finishes throughout. We provide a detailed written estimate after a thorough site visit so you have an accurate number before committing.
Yes. We manage all permitting and inspection coordination with St. Tammany Parish on every whole home renovation we complete in Mandeville.
