A great floor starts with what's underneath. You can buy the best hardwood in Los Angeles, but if the subfloor is uneven or damaged, that floor will squeak, gap, and fail early. You won't see the problem until it's too late. We get that. Before we install anything, we check what's under your floor and fix it right. This is the step that separates a floor that lasts from one that falls apart.

We level uneven subfloors, repair damage, and prep the surface so your new floor sits flat and tight. Concrete slab? Wood subfloor? Old, settling foundation? We handle it. Our team finds the trouble spots—dips, high points, soft areas—and corrects them before a single plank goes down. This is the work a lot of contractors skip to save time. We don't. It's the difference between a floor done right and one you'll be fixing again soon.

Picture a floor that stays flat, quiet, and solid year after year—because the base under it was done right. That's what we build. From the first inspection to the final prep, we never cut this corner. Choose I Know A Guy Flooring and start your floor on solid ground. Call today and take the first step.
