Whitby runs from historic Brooklin and Port Whitby streets to newer Williamsburg and Taunton North communities. Newer basements finish cleanly into theatres, gyms and family space, while mature homes benefit from moisture-first construction.
As one of Durham's most family-driven markets, Whitby basements become playrooms, in-law suites and income units. Whatever you start with, you end with finished square footage your family uses every week, and a number your Whitby house carries at resale.
What we build in Whitby basements
Basement finishing
Theatres, bars, gyms and family spaces. Wood studs with metal tracks and moisture-resistant drywall as standard, finished to match the rest of your home.

Whitby's north end was built for basements. Williamsburg, Taunton North and the newer phases of Brooklin went up from the late 1990s through the 2010s with poured-concrete foundations, ceilings over eight feet, larger windows and, in many homes, a bathroom rough-in already in the slab. That combination lets us skip the structural questions and go straight to design: theatre or open family room, bar size, whether the guest bedroom needs a full bath or a powder room.
Pringle Creek and the streets closer to the lake in Port Whitby are older, with 1960s and 1970s stock, lower ceilings and more moisture history. Nothing there worries us, but it changes the order of work. Drainage and waterproofing come first, then the finishes.
Permits go through the Town of Whitby building department, and a basement with a new bathroom or bedroom needs one. Our licensed structural engineer prepares and stamps the drawings, and we handle the application.
Our recent Whitby project on William Davidson Street finished 1,152 square feet for $90,000 to $100,000. That is the number to hold in your head for a full-width family basement with a bathroom, done to the standard the photos on this page show. From Richmond Hill, Whitby is about 45 minutes via the 407 and the 412, which puts Kam on site for the decisions that matter, not only the final walkthrough.
Every basement is priced from the same quote sheet, line by line. Permit drawings, 3D design and the lifetime workmanship warranty are included.
