Why Thornton

Basement Framing for Thornton’s Newer Homes

Thornton’s housing is the newest in our service area. Census estimates put close to half of its homes in 2000 or later, and the city sits in western Adams County at the north end of the metro. A newer house may still have its builder’s paperwork.

According to the Colorado Geological Survey, few areas in the Denver metro are completely free of potentially swelling soil, so newer construction is worth checking too. Plenty of Colorado basement floors are poured as floating slabs on purpose, and a wall tied to both the slab and the joists above works against that design.

→ Floating Wall Systems

Read the Builder’s Paperwork: A soils report or builder documents can show how your slab was built.

Keep the Gap Clear: No shims, blocking, or screws should bridge a floating wall’s gap.

Plan Around the Mechanicals: Keep the furnace and water heater reachable once the new rooms go up.

Questions Worth Asking First

Before any framing starts, find out what your slab was built to do and decide what each room is for. Then send a request, and expect to hear from us within one business day.
