From the Subfloor Up: What a Major Kitchen Renovation Really Looks Like
Kitchen — March 17, 2026
When a kitchen has truly seen better days, a coat of paint won't cut it. This is the story of a complete gut renovation in Upper Marlboro, Maryland — from tearing out rotted subfloor and removing walls to the stunning finished kitchen you see today.
When a Kitchen Needs More Than a Refresh There's a difference between a kitchen that needs updating and a kitchen that needs rescuing. The Upper Marlboro home we tackled in this project fell firmly into the second category. The original kitchen had decades of wear layered on top of deeper structural problems — damaged subfloor, load-bearing walls restricting the layout, outdated electrical and plumbing, and cosmetic finishes that were long past their useful life. The homeowners had a clear vision: an open, modern kitchen that felt spacious and bright, built to last for decades.

Before any new materials go in, the structure has to be right. There's no shortcut around this — skipping subfloor repair to save money is one of the costliest mistakes a homeowner can make, because all that beautiful new flooring and cabinetry will reflect any unevenness or soft spots beneath it within a year. Step 2: Subfloor Replacement Replacing a kitchen subfloor is unglamorous work, but it is absolutely foundational — literally. In this project, we removed the damaged sections of the existing subfloor and replaced them with 3/4" tongue-and-groove plywood, properly secured to the joists and leveled throughout. We used Home Depot's premium subfloor panels, which provide a stable, flat base for tile, hardwoo…
