TNT Design & Build holds CSLB license #1012379 as a Class B general building contractor in Carlsbad, established in 2008 with over 352 permitted projects logged through the City of Oceanside and surrounding jurisdictions. Kitchen gut-remodels involving custom tile backsplash and floor installations draw on the same precision substrate preparation that Know Howe Tile executes across North County residential projects. The design-build model integrates in-house architectural drafting, 3D rendering, material selection, and construction management for kitchens, bathrooms, whole-home renovations, room additions, and ADU construction under a single contract. Electrical panel upgrades from 100-amp to 200-amp service are a standard scope item on full kitchen remodels, overlapping with the residential panel and EV-charger wiring that Rowan Electric installs in Carlsbad homes. High-end kitchen projects specify quartzite countertop slabs cut to template with CNC waterjet tolerances of ±1/16 inch, undermount sink cutouts, and full-height bookmatched backsplash panels.
