Maple Leaf Basement specializes in three core services: regular basement finishing and renovation - transforming unfinished or outdated basements into family rooms, home theatres, gyms, offices, and guest suites; legal basement apartment construction - fully permitted, OBC-compliant secondary suites that generate $1,500–$2,800/month in rental income; and complete design, drawing, and permit management - the full pre-construction planning and permit administration service that supports both. Basements are all we do, and that singular focus makes us better at it than any general contractor serving the GTA.
